This study aimed to develop a valid and reliable instrument, the Mental Images of Scientists Questionnaire (MISQ), and use the instrument to examine Chinese students’ mental images of scientists’ characters across school levels, regions, living settings, and gender. The final version of the MISQ consisted of four constructs: scientists’ cognitive, affective, lifestyle, and job characters. The results showed that senior high school students gave higher scores for scientists’ cognitive character construct than junior high and elementary school students did. Students from eastern regions, which have a more highly developed economy, gave the highest scores on cognitive and affective character constructs of scientists. Students from western regions, which have a less developed economy, had a relatively negative impression of scientists. Students’ images of scientists’ affective, lifestyle, and job characters were positively correlated with their interests in pursuing scientific careers. Future research to explore the relationships between students’ mental images of scientists’ characters and students’ motivation to pursue science-related careers or to engage in scientific practices are recommended.

Despite advances in neuroscience, the mechanisms by which human brain resolve optical image formation through relational reasoning remain unclear, particularly its relationships with task difficulty. Therefore, this study explores the underlying brain dynamics involved in optical image formation tasks at various difficulty levels, including those with a single convex lens and a single mirror. Compared to single convex lens relational reasoning with high task difficulty, the single mirror relational reasoning exhibited significantly higher response accuracy and shorter latency. As compared to single mirror tasks, single convex tasks exhibited greater frontal midline theta augmentation and right parietal alpha suppression during phase I and earlier phase II, and augmentation of frontal midline theta, right parietal-occipital alpha, and left mu alpha suppression during late phase II. Moreover, the frontal midline theta power in late phase II predicts the likelihood of solving single convex tasks the best, while the parietal alpha power in phase I is most predictive. In addition, frontal midline theta power exhibited stronger synchronization with right parietal alpha, right occipital alpha, and mu alpha power when solving single convex tasks than single mirror tasks. In summary, having stronger brain dynamics and coordination is vital for achieving optical image formation with greater difficulty.

This study analyzed the impact of different analogical learning approaches (analogies or metaphors) integrated with different presentation modalities (pictures or texts) on middle school students’ learning performance of electricity with supporting evidence from their eye movement behaviors. Eighty ninth-grade middle school students were randomly assigned into four groups to receive four different versions of an online electricity learning program, including pictorial analogies, textual analogies, pictorial metaphors, and textual metaphors. Data regarding students’ eye movement behaviors were collected simultaneously during their online learning. All the students took a pre-test, post-test, and retention test covering their comprehension of electricity concepts. Our results revealed that the analogy group provided more mapping and integration behaviors between the analog and target concepts about electricity, resulting in gaining better performance than the metaphor group. Additionally, students receiving pictorial modality generated more mapping and integration behaviors between the analog and target concepts, resulting in a better understanding of electricity concepts than students learning with textual modality. The associated implications for analogical learning approaches and presentation modalities concerning science learning and eye movement behaviors are also discussed in the paper.

This study specifically focuses on examining whether the eye-tracking-supported metacognition would benefit science majors’ and nonscience majors’ scientific evidence-based reasoning performance. Thirty-nine science majors and forty-one nonscience majors were recruited to participate in an online scientific evidence-based reasoning task. Data regarding the students’ online learning process and eye movement behaviors were simultaneously collected. The results indicated that the science majors not only significantly outperformed the nonscience majors in terms of reasoning performance but also allocated significantly greater eye movements during their first time of processing scientific evidence-based reasoning task. Immediately after the task, the eye-tracking-supported metacognition provided each student with individualized feedback regarding their eye movement behaviors, such as their eye fixation sequence, durations, and locations. With such immediate feedback, the students were provided an opportunity to engage in self-monitoring, evaluating, and calibrating their approaches in order to revise their final answers. After the application of this eye-tracking-supported metacognition, both the science majors and the nonscience majors all made significant improvements in their scientific evidence-based reasoning performance. However, no statistically significant differences in the reasoning performance or visual attention of the science majors and nonscience majors were found. This study demonstrated that the use of eye-tracking-supported metacognition was not only able to maximize the performance of both the science majors and nonscience majors but that it also bridged the gap in performance between the two groups.

Eye movements are considered to be informative with regard to the underlying cognitive processes of human beings. Previous studies have reported that eye movements are associated with which scientific concepts are retrieved correctly. Moreover, other studies have also suggested that eye movements involve the cooperative activity of the human brain's fronto-parietal circuits. Less research has been conducted to investigate whether fronto-parietal EEG oscillations are associated with the retrieval processing of scientific concepts. Our findings in this study demonstrated that the fronto-parietal network is indeed crucial for successful memory retrieval. In short, significantly lower theta augmentation in the frontal midline and lower alpha suppression in the right parietal region were observed at the 5th eye fixation for physics concepts that were correctly retrieved than for those that were incorrectly retrieved. Moreover, the visual cortex in the occipital lobe exhibits a significantly greater theta augmentation followed by an alpha suppression following each eye fixation, while a right fronto-parietal asymmetry was also found for the successful retrieval of presentations of physics concepts. In particular, the study results showed that eye fixation-related frontal midline theta power and right parietal alpha power at the 5th eye fixation have the greatest predictive power regarding the correctness of the retrieval of physics concepts.

The 2015 Programme for International Student Assessment (PISA) has drawn a substantial amount of attention from science educators and educational policymakers because it marked the first time that PISA assessed students' ability to evaluate and design scientific inquiry using computer‐based simulations. We undertook a secondary analysis of the PISA 2015 Taiwan dataset of 7,973 students from 214 schools to identify critical issues of student learning and potentially reshape our educational system and policies. Thus, this study sought to identify potential latent clusters of students' scientific literacy performance according to a set of focus variables selected from the PISA student questionnaires. In addition, significant determinants of students' scientific literacy and resiliency were analyzed. Cluster analysis results demonstrated the presence of four clusters of high, medium, low, and inferior scientific literacy/epistemology/affective dispositions. Specifically, students in cluster 1 compared with other clusters showed that the higher the scientific literacy scores are, the more positive epistemic beliefs about science, achievement motivation, enjoyment of science, interests in broad science, science self‐efficacy, information and communications technology (ICT) interest, ICT autonomy, more learning time, more teacher supports and teacher‐directed instructions are. Regression results indicated that the most robust predictor of students' scientific literacy performance is epistemic beliefs about science, followed by learning time, interest in broad science topics, achievement motivation, inquiry‐based science teaching and learning practice, and science self‐efficacy. Decision tree model results showed that the descending order of the variables in terms of their importance in differentiating students as high‐ versus low‐performing were epistemic beliefs about science, learning time, self‐efficacy, interest in broad science, and scientific inquiry, respectively. A similar decision tree model to determine students as resilient versus non‐resilient also was found. Various interpretations of these results are discussed, as are their implications for science education research, science teaching, and science education policy.

Human memory retrieval is the core cognitive process of the human brain whenever it is processing the information. Less study has focused on exploring the neural correlates of the memory retrieval of scientific concepts when presented in word and picture modalities. Fewer studies have investigated the differences in the involved brain regions and how the brain dynamics in these regions would associate with the accuracy of the memory retrieval process. Therefore, this study specifically focused on investigating the human brain dynamics of participants when they retrieve physics concepts in word vs. pictorial modalities, and whether electroencephalogram (EEG) activities can predict the correctness of the retrieval of physics concepts. The results indicated that word modality induced a significant stronger right frontal theta augmentation than pictorial modality during the physics concepts retrieval process, whereas the picture modality induced a significantly greater right parietal alpha suppression than the word modality throughout the retrieval process spurred by the physics concept presentations. In addition, greater frontal midline theta augmentation was observed for incorrect responses than the correct responses during retrieve physics concepts. Moreover, the frontal midline theta power has greater negative predictive power for predicting the accuracy of physics concepts retrieval. In summary, the participants were more likely to retrieve physics concepts correctly if a lower amount of theta were allocated during the maintaining period from 2,000 ms through 3,500 ms before making responses. It provides insight for our future application of brain computer interface (BCI) in real-time science learning. This study implies that the lower frontal midline theta power is associated with a lower degree of cognitive control and active maintenance of representations as participants approach a correct answer.

Epilogue for the IJSME Special Issue: Metacognition for science and mathematics learning in technology-infused learning environments

Many studies have shown the positive impact of serious gaming on learning outcomes, but few have explored the relationships between game immersion and science learning. Accordingly, this study was conducted to investigate the effectiveness of learning by playing, as well as the dynamic process of game immersion experiences, and to further identify whether, and to what extent, immersion affects science learning through serious gaming by using the techniques of cluster analysis. A total of 63 seventh-grade students participated in the study, and a quasi-experimental research design was employed. The results demonstrated that the students gained a holistic understanding of the relevant scientific concepts because their performances on the scenario-based science assessment were significantly improved across serious gameplaying occasions, and the effect of learning was retained long term. Moreover, serious gaming provided students with the experience of immersion insofar as the students indicated a greater degree of immersion in the game over time. Furthermore, two core clusters presenting meaningful patterns, high gaming performance/high immersion and high science learning/low immersion, were revealed. Finally, various interpretations and implications of the obtained data are discussed. [ABSTRACT FROM AUTHOR]

Dynamic 3D representations enhanced students' performance.Dynamic 3D representations fostered students to allocate greater attention.Eye movements could predict students' 3D mental models of an atomic orbital.Low-spatial-ability students with dynamic 3D representations spent more attention. This study examined the effectiveness of the different spatial abilities of high school students who constructed their understanding of the atomic orbital concepts and mental models after learning with multimedia learning materials presented in static and dynamic modes of 3D representation. A total of 60 high school students participated in this study and were randomly assigned into static and dynamic 3D representation groups. The dependent variables included a pre-test and post-test on atomic orbital concepts, an atomic orbital mental model construction test, and students' eye-movement behaviors. Results showed that students who learned with dynamic 3D representation allocated a significantly greater amount of attention, exhibited better performance on the mental model test, and constructed more sophisticated 3D hybridizations of the orbital mental model than the students in the static 3D group. The logistic regression result indicated that the dynamic 3D representation group students' number of saccades and number of re-readings were positive predictors, while the number of fixations was the negative predictor, for developing the students' 3D mental models of an atomic orbital. High-spatial-ability students outperformed the low-spatial-ability students on the atomic orbital conceptual test and mental model construction, while both types of students allocated similar amounts of attention to the 3D representations. Our results demonstrated that low-spatial-ability students' eye movement behaviors positively correlate with their performance on the atomic orbital concept test and the mental model construction.

Video games possess many unique features that facilitate learning. Meanwhile, teaching about evolution is never an easy task due to the existence of some barriers to its learning. Virtual Age, therefore, has been developed in an attempt to harness the power of gaming to increase student understanding of biological evolution. The aim of this study was to examine whether Virtual Age is effective for learning about evolution and to further explore the interplay of student concept learning, gaming performance, and in-game behaviors. A total of 62 7th graders took part in the study, and significant findings were revealed. The students did learn by playing Virtual Age, and their long-term knowledge retention was promising. The in-game behaviors, such as times and duration of viewing the relevant information embedded in Virtual Age, were significantly related to gaming performance (game score), which subsequently influenced learning outcomes. Moreover, the results of cluster analysis indicated that three clusters of low learning outcomes/low gaming performance, high learning outcomes, and high gaming performance emerged. Overall, Virtual Age is an effective game for learning about evolution based on its sound and sophisticated design. Implications derived from the study and suggestions for future work are proposed. We examine whether Virtual Age is effective for evolution learning.We investigate situated gaming-learning interactions through Virtual Age play.Students did learn through Virtual Age play and knowledge retention was promising.Student in-game behaviors were related to gaming performance and learning outcomes.There were relations between prior domain knowledge, use of avatars, and learning.

This study investigated the effects of students’ prior science knowledge and online learning approaches (social and individual) on their learning with regard to three topics: science concepts, inquiry, and argumentation. Two science teachers and 118 students from 4 eighth-grade science classes were invited to participate in this research. Students in each class were divided into three groups according to their level of prior science knowledge; they then took either our social- or individual-based online science learning program. The results show that students in the social online argumentation group performed better in argumentation and online argumentation learning. Qualitative analysis indicated that the students’ social interactions benefited the co-construction of sound arguments and the accurate understanding of science concepts. In constructing arguments, students in the individual online argumentation group were limited to knowledge recall and self-reflection. High prior-knowledge students signific...

The purpose of this study is to explore the impact of problem solving instruction on 126 middle school students’ learning of physical science in terms of their scientific knowledge, scientific concept dependent reasoning and problem solving ability. This study used a quasi-experiment with one factorial design of instructional approaches (problem solving and traditional hands-on learning). Sixty-one students participated in problem solving while sixty-five students participated in traditional hands-on learning. Results indicate that the problem solving group significantly outperformed the traditional hands-on learning group for both immediate and retaining effect, regardless of scientific knowledge, scientific concept dependent reasoning and scientific problem solving abilities. The regression results also indicated that the scientific concept dependent reasoning test is the best predictor for scientific problem solving ability, followed by scientific knowledge itself. Our study demonstrates that students’ scientific knowledge, reasoning and problem solving all are successfully improved after receiving six weeks scientific problem solving.

The present study investigated the effects of online argumentation scaffolding on students’ argumentation involving hypothetical and theoretical biological concepts. Two types of scaffolding were developed in order to improve student argumentation: continuous scaffolding and withdraw scaffolding. A quasi-experimental design was used with four 8th-grade classes comprising a total of 124 students. Two classes (63 students) were assigned into the continuous scaffolding group, while the other two (61 students) were assigned into the withdraw scaffolding group. All the students participated in online argumentation regarding four units, including two hypothetical concepts and two theoretical concepts. Both online learning process and scientific argumentation assessment results indicated that the continuous scaffolding group performed significantly better in terms of the quality and quantity of argumentation than the withdraw scaffolding group with regard to the hypothetical biology concepts, particularly in generating rebuttal arguments. In addition, the results also showed that both the continuous group and withdraw group students had better argumentation performance with regard to the hypothetical biology concepts than the theoretical biology concepts. Taken together, the study results suggest that learning argumentation through theoretical biology concepts is more difficult than doing so through hypothetical biology concepts.

Despite decades of studies on the link between eye movements and human cognitive processes, the exact nature of the link between eye movements and computer-based assessment performance still remains unknown. To bridge this gap, the present study investigates whether human eye movement dynamics can predict computer-based assessment performance (accuracy of response) in different presentation modalities (picture vs. text). Eye-tracking system was employed to collect 63 college students' eye movement behaviors while they are engaging in the computer-based physics concept questions presented as either pictures or text. Students' responses were collected immediately after the picture or text presentations in order to determine the accuracy of responses. The results demonstrated that students' eye movement behavior can successfully predict their computer-based assessment performance. Remarkably, the mean fixation duration has the greatest power to predict the likelihood of responding the correct physics concepts successfully, followed by re-reading time in proportion. Additionally, the mean saccade distance has the least and negative power to predict the likelihood of responding the physics concepts correctly in the picture presentation. Interestingly, pictorial presentations appear to convey physics concepts more quickly and efficiently than do textual presentations. This study adds empirical evidence of a prediction model between eye movement behaviors and successful cognitive performance. Moreover, it provides insight into the modality effects on students' computer-based assessment performance through the use of eye movement behavior evidence.

This study examines the difference in effectiveness between two scientific inquiry programs—one with an emphasis on scientific reasoning and one without a scientific reasoning component—on students’ scientific concepts, scientific concept-dependent reasoning, and scientific inquiry. A mixed-method approach was used in which 115 grade 5 students were administered the scientific concept test, scientific concept-dependent reasoning test, and scientific inquiry test before, 1 week after, and 8 weeks after instruction. In addition, students’ scientific inquiry worksheets in the classroom were collected and evaluated. Results indicated that the experimental group outperformed the control group, regardless of scientific concept test, scientific concept-dependent reasoning test, and scientific inquiry test. Moreover, the classroom inquiry worksheets results demonstrated that the experimental group generated a significantly greater number of testable hypotheses, correct hypotheses, and correct evidence-based scientific explanations and a higher level of scientific reasoning than did the control group.

This study uses the Taiwan Programme for International Student Assessment (PISA) 2006 Main Survey and Taiwan PISA 2015 Field Trial survey datasets to investigate how self-evaluated values (i.e. personal and general) and cognitive factors (i.e. self-efficacy and self-concept) of two groups of Taiwanese 15-year-old students separated by 8 years of classroom-presented science instruction experience impact leisure engagement in science learning activities. To compare differences between these two groups, we verified the statistical fitness of a newly created five-factor model called the self-evaluated values and cognition, and engagement, which revealed a good model fit to both PISA datasets. Results from critical ratio for differences analyses showed a significant increase in pathway parameter strength for students’ personal value of science, and a significant decrease in pathway parameter strength for students’ science self-efficacy between the two PISA survey cycles. Examination of results and their importance for science educators, investigators, and policy-makers is also offered.

This study investigates the effect of Web-based Chemistry Problem-Solving, with the attributes of Web-searching and problem-solving scaffolds, on undergraduate students' problem-solving task performance. In addition, the nature and extent of Web-searching strategies students used and its correlation with task performance and domain knowledge also were examined. We recruited a total of 183 undergraduate students, all of whom are taking the freshman chemistry course, to participate in the study to solve three chemistry tasks across a semester. Mandated screen-capture software captured participants' on-screen Web-searching processes were recorded every five seconds. Results demonstrated that students' problem-solving performance was significantly improved from task 1 to 3, and students with more domain knowledge outperformed students with less domain knowledge. Students with higher problem-solving performance employed more existing knowledge and metacognitive Web-searching strategies; and students with lower problem-solving performance employed more cognitive Web-searching strategies. In addition, students' problem-solving performance was correlated with their domain knowledge, use of existing knowledge, and metacognitive Web-searching strategies. Moreover, students' use of existing knowledge was the major factor for predicting their problem-solving performance according to the regression model.

本研究旨在探討正向情緒及幽默對學生在科學問題解決時的成績表現、認知評估與事後情緒之影響。本研究針對國中生進行調查研究，共施測318位八年級學生，男生166 位、女生152 位。經進行t檢定及多變量變異數之統計分析後，研究結果顯示，在油醋分離之問題解決題目上，高正向情緒者在科學問題解決之成績表現、有趣程度之認知評估及事後之正向情緒，皆顯著高於低正向情緒者；在事後負向情緒上則顯著低於低正向情緒者。在鐵棒戳紙題目方面，高正向情緒者認知評估之挑戰、有趣、容易之分數，以及事後正向情緒皆顯著高於低正向情緒者。幽默版本激起之正向情緒是有比原始版本高。但幽默版本與原始版本在科學問題解決上之成績表現、認知評估與事後情緒上皆未達顯著差異。本研究可提供教師教學之參考，即如何營造正向情緒的學習氛圍及環境，來促進科學問題解決能力之學習。 This study investigates whether emotions and humor can influence science problem-solving performance, cognitive appraisal, and emotion after the event. This study conducts a survey of 318 junior high school students (166 Male and 152 Female). The statistical methods used to analyze the data are t test and multivariate analysis of variance (MANOVA). The results of this study are as follows: (1) When solving the scientific problem of Oil and Vinegar Separation, students with high positive emotions had superior science problem-solving performance, interest appraisal, and positive emotions after the event compared to students with low positive emotions; however, they experienced lower negative emotion after the event than low positive emotion students did; and (2) when solving the scientific problem of Can the Iron Bar Pierce the Paper, students with high positive emotions reported higher scores of cognitive appraisal (interest and difficulty) and positive emotion after the event, compared to students with low positive emotions. Additionally, humorous items produced more positive emotions compared to non-humorous items. However, no differences existed between the influence of humorous items and non-humorous items on science problem-solving performance, cognitive appraisal, and emotion after the event.

The purpose of this study is to examine the difference in effectiveness between two on-line scientific learning programs - one with an argumentation component and one without an argumentation component - on students' scientific argumentation ability and conceptual change. A quasi-experimental design was used in this study. Two classes of 8th grade students (the experimental group) received the on-line scientific argumentation learning program about chemical reaction, and the other two classes of 8th grade students (the control group) received the same on-line scientific learning program about chemical reaction, but without argumentation, for two weeks. All 140 students were administered the scientific conception test, conceptual change test, and argumentation test before, one week after, and eight weeks after learning. In addition, the experimental group students' on-line argumentation process was collected. Results showed that the students of the experimental group significantly outperformed the control group, regardless of scientific conceptions, conceptual change, and argumentation. Regression results indicated that hold of scientific conceptions is the best predicator for students' conceptual change, followed by argumentation ability. The quantity and quality of scientific arguments that students generated in a series of argumentation questions improved across the four topics. In addition, students also successfully changed their conceptions from pre- to post-driving questions across four topics. This clearly demonstrates that students' argumentation ability and conceptual change were both facilitated through receiving the on-line Synchronous Argumentation science learning program.

This study investigates the effects of two factors: the mode of problem‐solving instruction (i.e. Web‐based versus non‐Web‐based) and the level of academic achievement (i.e. high achievers versus low achievers) on students’ problem‐solving ability and biology achievement. A quasi‐experimental design was used, in which the experimental group received six weeks of Web‐based problem‐solving instruction in biology and the control group received non‐Web‐based problem‐solving instruction for the same content and for the same period of time. Pre‐, post‐ and retention tests of problem‐solving and biology achievement were administered before and at two different time intervals after the instruction. With the pretest scores as a covariate, the results of MANCOVA followed by protected univariate F tests suggest that Web‐based problem‐solving instruction has the potential to enhance and sustain the learner’s problem‐solving skills over an extended period of time.

This study explored the electroencephalography (EEG) dynamics during a chemistry-related decision-making task and further examined whether the correctness of the decision-making performance could be reflected by EEG activity. A total of 66 undergraduate students’ EEG were collected while they participated in a chemistry-related decision-making task in which they had to retrieve the relevant chemistry concepts in order to make correct decisions for each task item. The results showed that it was only in the anterior cingulate cortex (ACC) cluster that distinct patterns in EEG dynamics were displayed for the correct and incorrect responses. The logistic regression results indicated that ACC theta power from 300[Formula: see text]ms to 250[Formula: see text]ms before stimulus onset was the most informative factor for estimating the likelihood of making correct decisions in the chemistry-related decision-making task, while it was the ACC low beta power from 150[Formula: see text]ms to 250[Formula: see text]ms after stimulus onset. The results suggested that the ACC theta augmentation before the stimulus onset serves to actively maintain the relevant information for retrieval from long-term memory, while the ACC low beta augmentation after the stimulus onset may serve the function of mapping the encoded stimulus onto the relevant criteria that the given participant has held within his or her mind to guide the decision-making responses.

This study reports an adaptive digital learning project, Scientific Concept Construction and Reconstruction (SCCR), and examines its effects on 108 8th grade students' scientific reasoning and conceptual change through mixed methods. A one-group pre-, post-, and retention quasi-experimental design was used in the study. All students received tests for Atomic Achievement, Scientific Reasoning, and Atomic Dependent Reasoning before, 1 week after, and 8 weeks after learning. A total of 18 students, six from each class, were each interviewed for 1 hour before, immediately after, and 2 months after learning. A flow map was used to provide a sequential representation of the flow of students' scientific narrative elicited from the interviews, and to further analyze the level of scientific reasoning and conceptual change. Results show students' concepts of atoms, scientific reasoning, and conceptual change made progress, which is consistent with the interviewing results regarding the level of scientific reasoning and quantity of conceptual change. This study demonstrated that students' conceptual change and scientific reasoning could be improved through the SCCR learning project. Moreover, regression results indicated students' scientific reasoning contributed more to their conceptual change than to the concepts students held immediately after learning. It implies that scientific reasoning was pivotal for conceptual change and prompted students to make associations among new mental sets and existing hierarchical structure-based memory. 2009 Wiley Periodicals, Inc.

This study examined how middle school students constructed their understanding of the mitosis and meiosis processes at a molecular level through multimedia learning materials presented in different interaction and sensory modality modes. A two (interaction modes: animation/simulation) by two (sensory modality modes: narration/on-screen text) factorial design was employed. The dependent variables included subjects' pre-test, post-test, and retention-test scores, showing their understanding of mitosis and meiosis process at molecular level, as well as data of subjects' eye-movement behavior. Results showed the group that received animation with narration allocated a greater amount of visual attention (number of fixations, total inspection time, and mean fixation duration) than the group that received animation with on-screen text, in both pictorial area and area of interest, which is consistent with students' immediate and long-term retained learning of the processes of mitosis and meiosis. The group that received simulation with on-screen text allocated a greater amount of visual attention than the group that received simulation with narration, consistent with students' immediate and retained learning. The group that received simulation with on-screen text also allocated a greater amount of visual attention than the group that received animation with on-screen text, consistent with students' immediate and retained learning. This study adds empirical evidence of a direct correlation between the length of eye fixation behavior and the depth of learning. Moreover, it provides insight into the multimedia effect on students' cognitive process through the use of eye fixation behavior evidence.

This article reports research from a 3 year digital learning project to unite conceptual change and scientific reasoning in the learning unit of combustion. One group of students had completed the course combining conceptual change and scientific reasoning. The other group of students received conventional instruction. In addition to the quantitative data, six students from each group were interviewed to evaluate their conceptual change, correct concepts and scientific reasoning. Results indicate that the experimental group’s students significantly outperformed the conventional group on the Combustion Achievement Test (CAT), Scientific Reasoning Test (SRT) and Combustion Dependent Reasoning Test (CDRT). Moreover, the experimental group’s students use higher levels of scientific reasoning more frequently and changed their alternative concepts more successfully than did the conventional group. Furthermore, once the experimental group’s students’ successfully changed their conceptions, their concepts tended to be more stable than the conventional group’s students, even after the 6th week of learning. These results demonstrate that combining conceptual change and scientific reasoning indeed improves students’ conceptual change and scientific reasoning ability more effectively than conventional instruction.

To alleviate these difficulties of students learning atomic orbital concepts, this study developed different 3D animations to foster students to generate better learning performance and their sophisticated mental models. The study also explored students' eye movement behaviors. All 60 high school students received the pre- and post-test of atomic orbital concept test and mental model test before and immediately after learning from either static or dynamic 3D animations. The results indicated that the performances of students' mental models are influenced by different 3D animations mode. With respect to eye movements, students who received dynamic 3D animations allocated greater number of fixation, number of saccade, and longer total inspection time as well as saccade distance than those who received static 3D animations. These findings have implications for how to develop well-designed instruction to foster students' learning performance and for the relationship between eye movement behaviors with learning performance.

There is considerable disagreement among researchers about chemistry learning approach. Some have been said to demonstrate an individual advantage, some a social advantage. While there is a great deal of general literature on this field, however, the specific web-based conductive learning is relatively unexplored. We proposed a Chemistry Online Argumentation Courseware (COAC) for enhancing 10th grade students' learning with website exploring conductive components where senior high school students can easily navigate the embedded website links and create effective scientific arguments. The purpose of this paper is to report on an investigation of learners' online argumentation activity. Answers were sought to the question: how does the website exploring strategy influence students' argumentation performance on our conductive COAC. Qualitative results suggested that both Individual and Social group learners had significant improvements in their argumentation ability with the support of website exploring. This study further suggested that the benefit of website exploring argumentation-strategies instruction to the Individual group learners in the chemistry course, they improved fast enough to attain the same progress as the collaborative learners regarding argumentation-based learning. The findings of this study could serve as some general principles for teachers who would like to improve students' website learning strategy use.

The present study was to explore undergraduate students' performance and eye movement between two groups (non-science major and science major) on online scientific literacy assessments. The domain of scientific literacy in assessments consisted of identifying scientific questions, explaining phenomena scientifically, and using evidence scientifically. Eye-tracking system was synchronized to collect the indicator data of eye movement while students were engaging in cognitive processing during the assessments. The results showed that the science group students outperformed significantly than their peers in the non-science group on the assessments. Eye movement data further supported that the science group students allocated greater attention and made deeper cognitive processing at area of interest (AOI) on critical web pages compared to the non-science group ones. This study provides empirical evidence that the eye movement behaviors can give an insight into the information processing during scientific literacy online assessments.
