- Abstract
Computer-based interventions are being used more in the classroom. Student responses to these interventions often contribute to decisions making regarding important outcomes. It is important to understand the effect of these interventions within the context of the intervention as well as across related context. The current study examined the generalization of math fact fluency gains resulting from a computer-based intervention to paper-and-pencil performance. A total of 31 second grade students completed fluency drills on the computer or with paper and pencil. Pretest-posttest performance on both computer and paper and pencil for all students was evaluated using a doubly multivariate repeated measure ANOVA. Results indicated that gains achieved on the computer did not generalize to paper-and-pencil performance., (Copyright © 2012 Society for the Study of School Psychology. Published by Elsevier Ltd.

107. The Mobile Fact and Concept Textbook System (MoFaCTS) Computational Model and Scheduling System
- Author

Pavlik, Philip I. and Eglington, Luke G.
- Abstract
An intelligent textbook may be defined as an interaction layer between the text and the student, helping the student master the content in the text. The Mobile Fact and Concept Training System (MoFaCTS) is an adaptive instructional system for simple content that has been developed into an interaction layer to mediate textbook instruction and so is being transformed into the Mobile Fact and Concept Textbook System (MoFaCTS). In this paper, we document the several terms of the logistic regression model we use to track performance adaptively. We then examine the contribution of each component of our model when it is fit to 4 semesters of Anatomy and Physiology course practice data. Following this documentation of the model, we explain how it is applied in the MoFaCTS system to schedule performance by targeting practice for each item at an optimal efficiency threshold.

- Abstract
Purpose: This paper defines and assesses student learning patterns under the influence of problem-based learning (PBL) and their classification into a reasonable minimum number of classes. Study utilizes PBL implemented in an undergraduate Statistics and Operations Research course for techno-management students at a private university in India. Design/methodology/approach: Study employs an in situ experiment using a conceptual model based on learning theory. The participant's end-of-semester GPA is Performance Indicator. Integrating PBL with classroom teaching is unique instructional approach to this study. An unsupervised and supervised data mining approach to analyse PBL impact establishes research conclusions. Findings: The administration of PBL results in improved learning patterns (above-average) for students with medium attendance. PBL, Gender, Math background, Board and discipline are contributing factors to students' performance in the decision tree. PBL benefits a student of any gender with lower attendance. Research limitations/implications: This study is limited to course students from one institute and does not consider external factors. Practical implications: Researchers can apply learning patterns obtained in this paper highlighting PBL impact to study effect of every innovative pedagogical study. Classification of students based on learning behaviours can help facilitators plan remedial actions. Originality/value: 1. Clustering is used to extract student learning patterns considering dynamics of student performances over time. Then decision tree is utilized to elicit a simple process of classifying students. 2. Data mining approach overcomes limitations of statistical techniques to provide knowledge impact in presence of demographic characteristics and student attendance.

- Abstract
Recent developments in microscopy and image processing have made digital measurements on high-resolution images of fibrous materials possible. This helps to gain a better understanding of the structure and other properties of the material at micro level. In this paper SEM image segmentation based on mathematical morphology is proposed. In fact, paper models images (Whatman, Murillo, Watercolor, Newsprint paper) selected in the context of the Euro Mediterranean PaperTech Project have different distributions of fibers and fillers, caused by the presence of SiAl and CaCO3 particles. It is a microscopy challenge to make filler particles in the sheet distinguishable from the other components of the paper surface. This objectif is reached here by using switable strutural elements and mathematical morphology operators.

- Abstract
Presented are papers and programs generated as part of a Madison, Wisconsin project to develop a public school educational program for severely handicapped students. Three introductory papers deal with topics such as teacher training, litigation over questions of overinclusion and overexclusion, and what the practitioner needs from the researcher to develop public school programs for low-functioning individuals. Four language and reading skill programs are reported on the following topics: teaching pronouns, developing chart story reading skills, and improving reading comprehension. In the area of math, a developmental math skill sequence and a method for teaching students to solve addition problems are provided. Three papers on development of independent community living skills include an instructional model for developing home living skills, a family-life curriculum, and a method for teaching use of the telephone. Also included are a paper on training parents in child management and one on increasing the speech intensity of a retarded-emotionally disturbed student. (LS)

Anela Hrnjicic and Adis Alihodžic
- Abstract
Understanding the concepts related to real function is essential in learning mathematics. To determine how students understand these concepts, it is necessary to have an appropriate measurement tool. In this paper, we have created a web application using 32 items from conceptual understanding of real functions (CURF) item bank. We conducted a psychometric analysis using Rasch model on 207 first-year students. The analysis showed that CURF is a dependable and valid instrument for measuring students' CURF. The test is uni-dimensional; all items are consistent with the construct and have excellent item fit statistics. The results indicate that the items are independent of each other and unbiased towards the gender and high school background of the students.

Maryland Univ., College Park. Reading Center. and Ribovich, Jerilyn K.
- Abstract
The papers contained in this volume are the result of nine seminars conducted during 1972 and the first half of 1973. One concern that dominates many papers is the preparation of individuals for the teaching role. O'Neill reports the evaluation results of a preservice program that maximizes the use of field experiences; Duffey discusses the results of his study designed to evaluate undergraduates in social studies methods courses; Ashlock presents a rationale for the need of certification for elementary school mathematics specialists; after analyzing texts used in reading methods courses, Moretz and Davey assert the need for more consistent use of reading terminology; Amershek urges professional competence as the criterion for the selection of staff members for preschool programs. Another concern reflected in many of the papers is the nature of school programs for learners. Maley describes the impact of a reading emphasis industrial arts program; Gantt advocates a focus on the child's educational environment; Shields discusses reading in the kindergarten; and Hall and Ribovich build a rationale for teaching reading as a form of communication. Following each paper is a brief summary of participant reactions. (WR)

130. An Investigation of the Relationship between the Parents' Math Literacy Self-Efficacy and Their Math Anxieties
- Author

Akkaya, Sümeyra and Polat, Kübra
- Abstract
Mathematics anxiety can be defined as negative feelings towards mathematics and mathematical operations in general. Math anxiety is seen in many students, and even in parents. In fact, parents' own anxiety regarding mathematics may lead to their children experiencing angst over the subject as well. This can be a problem considering parents are considered one of the basic components of education and have important responsibilities to guide the education process of their children. Mathematical literacy is one of the research topics that have come into prominence in recent years due to PISA. Consequently, the purpose of this study is to determine the relationship between the parents' mathematical literacy self-efficacy and mathematics anxieties. Additionally, through examining the participation of parents in mathematic teaching during the COVID-19 pandemic, it is hoped to better understand their views and methodologies. All participants in this study are parents themselves. The study is designed with an explanatory sequential design among mixed method research designs. The grade in which the students are educated does not make any difference in the self-efficacy and anxiety perceptions of the parents regarding their mathematics literacy. Also, the parents' mathematical literacy self-efficacy and anxiety levels were high. [Paper presented at International Congress of Educational Research (13th, Hatay, Turkey, Sep 3-6, 2020).]

- Abstract
Prospective secondary mathematics teachers in Australia are typically taught by mathematics educators and mathematicians who work in different faculties and seldom collaborate--a situation that can lead to conflicting views about how to teach mathematics. This paper reports on findings from semi-structured interviews with three mathematics teacher educators in a hybrid mathematics/mathematics education department. Valsiner's zone theory is used to analyse how their beliefs, institutional context and professional learning opportunities shape their identities as MTEs. Findings reveal that the MTEs had developed similar beliefs within supportive institutional context but drew on different sources of professional learning.

Mathematics Education Research Group of Australasia (MERGA), Quane, Katherine, Chinnappan, Mohan, and Trenholm, Sven
- Abstract
Ascertaining young children's attitudes towards mathematics has its challenges. Methodologically, limitations exist regarding the type of research techniques that can be employed. The use of children's drawings as a data source has both methodological affordances and issues. The study was conducted with 106 children in Years 2 and 3 from three South Australian primary schools. This paper identifies some of the methodological affordances and issues of using children's drawings to ascertain and describe their attitudes towards mathematics. [This paper is the third in a symposium of three papers. For the first paper, "Drawings Reveal Young Students' Multiplicative Visualisation," see ED616196.

- Abstract
Bayesian Knowledge Tracing, a model used for cognitive mastery estimation, has been a hallmark of adaptive learning research and an integral component of deployed intelligent tutoring systems (ITS). In this paper, we provide a brief history of knowledge tracing model research and introduce pyBKT, an accessible and computationally efficient library of model extensions from the literature. The library provides data generation, fitting, prediction, and cross-validation routines, as well as a simple to use data helper interface to ingest typical tutor log dataset formats. We evaluate the runtime with various dataset sizes and compare to past implementations. Additionally, we conduct sanity checks of the model using experiments with simulated data to evaluate the accuracy of its EM parameter learning and use real-world data to validate its predictions, comparing pyBKT's supported model variants with results from the papers in which they were originally introduced. The library is open source and open license for the purpose of making knowledge tracing more accessible to communities of research and practice and to facilitate progress in the field through easier replication of past approaches.

The administration of A/B exams usually involves the use of items. Issues arise when the pre-establishment of a question bank is necessary and the inconsistency in the knowledge points to be tested (in the two exams) reduces the exams ‘fairness’. These are critical for a large multi-teacher course wherein the teachers are changed such that the course and examination content are altered every few years. However, a fair test with randomly participating students should still be a guaranteed subject with no item pool. Through data-driven decision-making, this study collected data related to a term test for a compulsory general course for empirical assessments, pre-processed the data and used item response theory to statistically estimate the difficulty, discrimination and lower asymptotic for each item in the two exam papers. Binary goal programing was finally used to analyze and balance the fairness of A/B exams without an item pool. As a result, pairs of associated questions in the two exam papers were optimized in terms of their overall balance in three dimensions (as the goals) through the paired exchanges of items. These exam papers guarantee their consistency (in the tested knowledge points) and also ensure the fairness of the term test (a key psychological factor that motivates continued studies). Such an application is novel as the teacher(s) did not have a pre-set question bank and could formulate the fairest strategy for the A/B exam papers. The model can be employed to address similar teaching practice issues.

Computer-based curriculum-based measurement (CBM) is a relatively common practice, but surprisingly few studies have examined the reliability of computer-based CBM. This study sought to examine the reliability of CBM administered via paper/pencil versus the computer. Twenty-one of 25 students in two third-grade classes (N = 21) participated in two generalizability studies. The primary facet of interest, format of assessment, was examined for two measures, a fact operation (fact family measure) and a more complex operation (multidigit addition). Researchers administered four alternate forms of each measure under both computer and paper/pencil conditions. Results indicated ideal reliability of measurement within all conditions and results were consistent across assessment formats for the fact operation. However, assessment format explained a large proportion of variance for the more complex skill (multidigit addition). Results indicate a need to consider the reliability of transitioning assessment from paper/pencil to computer-based response on a measure-by-measure basis. [ABSTRACT FROM AUTHOR]

The fibre characteristics of five Spondia mombin stands were studied to determine their suitability for pulp and paper production. Wood slivers obtained parallel to grain at three (3) different positions along the bole were macerated in combined identical amounts of glacial acetic acid plus hydrogen peroxide under heat at between 80-100o C. Macerated fibres were washed clean of mixture and mounted on slide for microscopic examination of fibre characteristics. Completely Randomized Design (CRD) was employed for the experiment. Data were analysed using one-way Analysis of Variance (ANOVA) while, the Duncan’s Multiple Range Test (DMRT) was used to separate means of significant differences among the treatments. Results show that significant differences existed in fibre characteristic of sampled trees, however the fibre length ranged from 0.98-1.0 mm, fibre diameter (18.22-21.47 um), lumen width (10.90-12.98 um) and cell wall thickness (3.86-4.60 um). Significant differences were also observed among the derived fibre characteristics, the Runkel ratio ranged from 0.66-8.89, elasticity coefficient (57.22-60.50 %), coefficient of rigidity (19.78-22.24 %), slenderness ratio (43.27-46.5). This implied that, the fibres of S. mombin were short and elastic which make the wood species an appropriate raw material for pulp and paper making especially when blended with other long fibre species.

- Abstract
The Indian Institute of Science is proud to host the fully in-person sixteenth iteration of the International Conference on Educational Data Mining (EDM) during July 11-14, 2023. EDM is the annual flagship conference of the International Educational Data Mining Society. The theme of this year's conference is "Educational data mining for amplifying human potential." Not all students or seekers of knowledge receive the education necessary to help them realize their full potential, be it due to a lack of resources or lack of access to high quality teaching. The dearth in high-quality educational content, teaching aids, and methodologies, and non-availability of objective feedback on how they could become better teachers, deprive our teachers from achieving their full potential. The administrators and policy makers lack tools for making optimal decisions such as optimal class sizes, class composition, and course sequencing. All these handicap the nations, particularly the economically emergent ones, who recognize the centrality of education for their growth. EDM-2023 has striven to focus on concepts, principles, and techniques mined from educational data for amplifying the potential of all the stakeholders in the education system. The spotlights of EDM-2023 include: (1) Five keynote talks by outstanding researchers of eminence; (2) A plenary Test of Time award talk and a Banquet talk; (3) Five tutorials (foundational as well as advanced); (4) Four thought provoking panels on contemporary themes; (5) Peer reviewed technical paper and poster presentations; (6) Doctoral students consortium; and (7) An enchanting cultural programme.

Gustavo Simas da Silva and Vânia Ribas Ulbricht
- Abstract
ChatGPT and Bard, two chatbots powered by Large Language Models (LLMs), are propelling the educational sector towards a new era of instructional innovation. Within this educational paradigm, the present investigation conducts a comparative analysis of these groundbreaking chatbots, scrutinizing their distinct operational characteristics and applications as depicted in current scholarly discourse. ChatGPT emerges as an exemplary tool in task-oriented textual interactions, while Bard brandishes unique features such as Text-To-Speech (TTS) functionality, which enhances accessibility and inclusive education, as well as integration with Google Workspace applications. This research critically examines their utilization in various spheres such as pedagogy, academic research, Massive Open Online Courses (MOOCs), mathematics, and software programming. Findings accentuate ChatGPT's superior efficacy in content drafting, code generation, language translation, and providing clinically precise responses, notwithstanding Bard's significant potential encapsulated in its exclusive features. Furthermore, the study traverses' crucial ethical aspects, including privacy concerns and inherent bias, underscoring the profound implications of these Artificial Intelligence (AI) technologies on literature and advocating against the indiscriminate reliance on such models.

The fiber of paper mulberry, which is mostly grown in the East Asian region, varies in both length and width—even if from the same species—depending on the country, soil, and climate where it is grown. This accounts for differences in the quality of handmade paper between domestic and imported products. Once handmade paper is manufactured as sheets, its origin cannot be determined from a morphological perspective, regardless of macroscopic and microscopic observations. Therefore, this study attempted to determine the origin of Korean and imported products using mulberry bast fiber and handmade paper from a chemometrics perspective. The inorganic components of wood are absorbed from the soil and exist in the bark of trees; thus, metal and rare-earth elements in the bast fibers and handmade papers were quantitatively analyzed using inductively coupled plasma-atomic emission spectroscopy/mass spectrometry (ICP-AES/MS). Following this, a prediction model of their origin was constructed by applying multivariate statistical analysis, i.e., a partial least squares-discriminant analysis (PLS-DA) loading plot was constructed, which helped in identifying the discrimination factors resulting from their origin. According to the ICP-AES results, Pb was only detected in the Gyeongbuk Mungyeong dak sample of the Korean bast fibers. The Chinese bast fiber sample had high contents of Ca, and B and Zn were detected only in the Chinese bast fiber samples. Bast fiber samples from China, Japan, and Thailand showed relatively high contents of Al, Ca, and Na. Meanwhile, Cu and Zn were detected in the handmade paper manufactured from the imported materials. According to the ICP-MS results, among the Korean handmade papers, the products from Gyeongbuk Mungyeong, Andong, and Chungbuk Goesan exhibited a high U content and that from Gapyeong had high Sc, Rb, Sr, and Ba contents. Thus, the elemental analysis employed in this study effectively identified the origin of the papers. The origin prediction by PLS-DA for the domestic and imported products revealed an accuracy of 86.4% and 72.7% for ICP-AES and ICP-MS methods, respectively, which is deemed acceptable to assess the origin. We believe this method significantly contributes to determining the origin of paper mulberry bast fiber and handmade paper manufactured in East Asia.

144. A Study of the I Don't Know Response in Multiple-Choice Tests. Iowa Testing Programs Occasional Papers, No. 5.

- Abstract
Multiple-choice standardized achievement tests of English vocabulary and reading comprehension and of mathematics were administered to samples of 592 grade eight students and 615 grade five students. Two forms of each test unit were prepared. The control groups took forms containing items with four responses, while the experimental groups took forms which had an additional response of I don't know. A few fictitious vocabulary items having no right answers were included in each of the English test units. In grade eight tests the mean scores of the control groups were higher. For the grade five samples there were no differences in mathematics; and differences in English (the control group obtaining higher scores) were found only for low ability students. Item discrimination indices obtained from the two forms did not show any significant differences. There was a negative linear relationship between percentage choosing the I don't know response and percentage correct. In general, lower ability students used the response more often than those with higher ability excePt in the case of the fictitious items. Sex differences were also found to be a factor in the use of the I don't know response. (Author/MV)

- Abstract
In 1976, New Jersey public law established uniform statewide minimum standards in the basic communication and computational skills for publicly educated students in the state. To implement the law for the year 1976-77, the New Jersey Educational Assessment Program administered tests to all fourth, seventh, and tenth grade students. These tests were used as the indicator of minimum basic skills proficiency. Students who did not correctly answer at least 65% of the test items did not satisfy the minimum proficiency requirement in that subject. Statewide, 90.4% of the fourth grade students met or exceeded the minimum standard on the reading test. In fourth grade mathematics, 72.1% of the students surpassed the minimum standard. In seventh grade, 74.2% of the students exceeded the statewide proficiency level in reading, while 60.4% did so in mathematics. Tenth grade results indicated that 77% of the students met the statewide criterion in reading, while 74% did so in mathematics. More students from higher socioeconomis status districts surpassed the minimum proficiency level than did students from lower socioeconomic categories. Also, more students from suburban and regional school districts exceeded the minimum level than did students from urban and rural districts. Behavioral objectives for reading and mathematics in the three grade levels are appended. (Author/MV)

146. High School Students' Perceptions of Social Studies. Occasional Paper No. 6.

- Abstract
Students in eight urban and three suburban high schools were asked for their perceptions of social studies, mathematics, and English. Although most students thought that learning all three subjects was important, they believed that learning social studies was less important than learning mathematics and English. The majority thought that their grade in social studies was more important than learning the subject. The students felt that their parents, counselors, and friends supported these views. Fewer than one-third of the urban students were high on measures of articulation between social studies and future occupations. Social studies teachers were generally perceived as little different from other teachers on affective measures and only slightly higher as interested in students as people. Social studies was perceived as being easier than mathematics, a finding which tends to be reflected in students' grades. Problem areas for teachers of social studies are noted, and suggestions for dealing with them are offered. (Author/ND)

- Abstract
Results of the second year of the New Jersey Minimum Basic Skills Tests in reading and mathematics, mandated by the New Jersey Public School Education Act of 1975, are summarized. Approximately 397,000 students in grades three, six, nine, and eleven were tested. Results of the tests showed that a smaller percentage of sixth-grade students met statewide standards than any other tested grade, confirming previous state and national findings of decreased performance in the intermediate grades. Other findings showed relationships between student achievement and socioeconomic status, type of community in which the school district is located, and region of the state. Tables summarizing results are included, along with appendices outlining required minimum competencies for each grade, and the procedures used to determine cutting scores. (MH)

148. Differences Between Teachers' Attitudinal Self-Ratings and Their Principals' Teacher Ideal on a Mathematics Inventory. Research Paper No. 14.

- Abstract
One hundred forty-eight secondary school principals were chosen at random and asked to select one teacher at random from the mathematics faculty of their schools. Both were administered the Mathematics Inventory for Teachers, an instrument designed to measure attitudes toward mathematics as a subject and toward its teaching. The principals were asked to respond as they believed an ideal mathematics teacher would, while the teachers were asked to express their own beliefs and opinions. The results were factor analyzed, and the principals and teachers differed in two of the eight factors. It appears that teachers are not as responsive to student needs as their principals would have them be. The principals would have their teachers give more attention to students who are having difficulty learning the subject. In addition, the principals' responses showed a more narrow, conservative conception of the function of mathematics instruction while the teachers were more cognizant of the need for higher order outcomes in mathematics.

- Abstract
The derivation and analysis presented in this report allow the experimenter to perform multifactor contrasts on correlation coefficients for several populations in an experimental design. Cells of the design constitute independent groups of subjects on which two measures have been taken and correlated. Measures need not be identical for each group. An example is given in which the dependent variable represents the correlation between attitude and achievement for six secondary school science classes stratified by ability (three levels) and grade level (two levels). An overall relationship was observed between science attitude and knowledge of science for junior and senior high school students of science. No difference due to achievement was found, but the grade difference was significant. (Author/BB)

- Abstract
A staff development needs assessment survey was conducted by the Adult Literacy Resource Institute, in cooperation with other Boston-area programs providing basic education services for adults, to gather information on what users and potential users of the institute wanted in the areas of inservice teacher education, training, and staff development activities for the coming years. Questionnaires were sent individually to 89 staff people of programs within the Boston Adult Literacy Initiative, and to people at 67 other programs (with an unknown number of total staff) doing basic education for adults. These recipients, in turn, were asked to distribute copies of the questionnaire to the staff at their programs. A total of l89 questionnaires were returned, 30 percent from initiative program questionnaires were returned, 30 percent from initiative program staff and 70 percent from other program staff. The rank order of categories of topic areas for inservice training chosen by the respondents were: (1) general basic education for adults (47%); (2) program administration (44%); (3) counseling (36%); (4) teaching English as a Second Language (33%); (5) teaching reading (32%); (6) teaching writing (3l%); (7) teaching in a credential program (20%); (8) teaching math (l6%); and (9) others (6%).
