Dyslexia is a type of Specific Learning Disability (SLD) that affects the educational development of a student, as it is the reason of difficulties not only in writing or reading but also in other disciplines like Mathematics. Research has proven that Information and Communication Technologies (ICT) can have a positive effect to the educational development of a dyslexic student. In this paper, twenty 6 th -grade primary-school students were observed while using computers during exams - ten with Dyslexia and ten with no SLDs. All students were called to solve a digital test and a paper test that were including some basic mathematic operations. The researcher recorded and examined the differences between the results from the two tests. Descriptive and deductive statistical analysis showed that students had better results when examined via a computer compared to a traditional written examination. [ABSTRACT FROM AUTHOR]

The article explores curvature with paper models. It states that to study both Euclidean and non-Euclidean geometries discovered by Janos Bolyai, Nikolai Lobachevsky and Bernhard Riemann as curved surfaces, a concept of curvature dating to Carl Friendrich Gauss is used by differential geometers. It examines how the curvature of curves and surfaces is related to the angles of polygons or polygonal curves and solid angles at the vertices of polyhedra. Examples of paper models that use Descartes' version of curvature to explore hyperbolic and elliptic figures in a precise and accessible way are presented.

This paper reports on the development and use of a Blueprint for Rural Mathematics (herein referred to as the Blueprint) in a study of middle-primary mathematics teaching. The study presented a counter-narrative to the deficit discourse around rural education outcomes through an emic perspective of middle-primary mathematics on the Yorke Peninsula, a rural district in southern Australia. This study defined 'rural' as a sociological and geographical phenomenon. It takes a sociological stance acknowledging the situatedness of the rural and the social and cultural uniqueness of the people and their communities. Geographically, the rural locations in this study were those distanced from, and outside the commuting zone of, large urban areas and major cities. This study claimed that rural schools of Yorke Peninsula are unresearched, undertheorised and underestimated in their teaching of mathematics. Hence, very little was known about the experiences of the Yorke Peninsula teachers or the pedagogical practices they employed in their mathematics teaching. Yorke Peninsula people have an identity of deficit imposed on them with no opportunity to negotiate it. In understanding and addressing the accuracy of this pervasive negative framing, this study investigated Yorke Peninsula teachers of mathematics. It concluded that the rural social space, the identity of its members, and teacher pedagogy are essential considerations in mathematics teaching. The Blueprint provides a framework to explore these key components of rural education. [ABSTRACT FROM AUTHOR]

CRITICAL thinking ,MATHEMATICS ,ENGINEERING education - Abstract
Purpose: The paper aims to examine the casual role of higher-order thinking skills as a mediator in the relationship between students' strength in mathematics and achievement in electrical and electronic engineering education. Design/Methodology/Approach: The study adopted a quantitative research design where random cluster sampling was used to select a total of 488 final-year students from four technical universities in Ghana. Mathematics achievement tests were used to gather data on students' higher-order thinking skills and competence in five areas of mathematics. Also, their examination results were collected from their respective universities. Mediation analysis was done using AMOS 26. Finding: The study revealed that the positive effect of students' strengths in the five selected mathematics topics on their performance in electrical and electronic engineering education is mediated by their higher-order thinking skills. Conclusion: The research concludes that there is a partial mediation in the relationship between students' strength in mathematics and achievement in electrical and electronic engineering education by higher-order thinking skills. Research Limitations: It is recommended that further researchers carry out similar research with more mathematics indicators to explain more variations in achievement in electrical and electronic engineering education. Practical Implication: Engineering mathematics curriculum developers should stress the need for mathematics, especially algebra, for the development of higher-order thinking skills to facilitate problem-solving in electrical and electronic engineering education and practice. Contribution to Literature: This study highlights the relationship between the understanding of the concepts of specific mathematics topics, higher-order thinking skills, and achievement in electrical and electronic engineering education.

LANGUAGE models ,MACHINE learning ,CHATGPT ,MATHEMATICS ,DETECTIVES - Abstract
Written answers to open-ended questions can have a higher long-term effect on learning than multiple-choice questions. However, it is critical that teachers immediately review the answers, and ask to redo those that are incoherent. This can be a difficult task and can be time-consuming for teachers. A possible solution is to automate the detection of incoherent answers. One option is to automate the review with Large Language Models (LLM). They have a powerful discursive ability that can be used to explain decisions. In this paper, we analyze the responses of fourth graders in mathematics using three LLMs: GPT-3, BLOOM, and YOU. We used them with zero, one, two, three and four shots. We compared their performance with the results of various classifiers trained with Machine Learning (ML). We found that LLMs perform worse than MLs in detecting incoherent answers. The difficulty seems to reside in recursive questions that contain both questions and answers, and in responses from students with typical fourth-grader misspellings. Upon closer examination, we have found that the ChatGPT model faces the same challenges. [ABSTRACT FROM AUTHOR]

LIMITED English-proficient students ,TEACHER development ,FOREIGN language education ,MATHEMATICS ,RESEARCH questions - Abstract
Due to rapid immigration, many children worldwide are learning mathematics in a second or additional language. This language diversity can be challenging for both teachers and students and carries profound implications for mathematics educators. Research shows that teachers use various ways to support English Language Learners. Research on multilingualism in mathematics classrooms has often focused on qualitative research. This meta-analysis aims to explore the statistically effective successful teaching practices from the studies using quantitative or mixed-method research approaches and aims to inform the research field in a cumulative manner. The specific research question that guided this meta-analysis is: What is the evidence regarding successful teaching of mathematics for Year 1–10 English Language Learners from 2009–2019 in countries where curricula are delivered predominantly in English? Four successful intervention categories were identified: Dual Language Programmes, Curriculum integration, Teacher Professional Development, and Cognitively Focused Interventions. The paper concludes with recommendations for practice and further research in this area. [ABSTRACT FROM AUTHOR]

As part of a longitudinal study focused on mathematical play, we (Melissa, Amy, and Anita) are often faced with questions about what counts as play and what mathematics (and other learning) we see in play, and whose play is most likely to be seen or dismissed. Rather than discuss our findings from classroom videos of kindergarten children engaged in mathematical play, we asked scholars who bring different lenses to research on play, young children, and teaching and learning mathematics to look at some of our data and provide their perspectives. In this session, we will share video and discuss with our panel (Nathaniel, Naomi, and Tran) various ways to interpret that video. This paper provides background on the potential of mathematical play and the details of the study that generated data for analysis. We conclude with a copy of a transcript that is associated with a video we will watch during the plenary with hopes that participants will watch prior to the session and come with their own questions/perspectives.

MATHEMATICS ,COMPUTER programming ,PROBIT analysis ,BIOLOGICAL assay ,REGRESSION analysis - Abstract
Using the probit analysis technique, mathematical algorithm and MATLAB computer program have been implemented in this paper to calculate both the Log-Dose (LD) and the Effective-Dose (ED) for any given percent. The probit analysis uses a successive weighted simple linear regression of experimental or row data. The kind of row data obtained from the bioassays should be generally in percent response (mortality or affected) at the corresponding doses (or concentrations). The response should be always in binomial form (e.g. death/no death) and the relationship between the response and the various doses or concentrations is always sigmoid or non-linear. The probit analysis here acts as a transformation from sigmoid or non-linear relationship to linear one and then uses a successive weighted simple linear regression on the linear relationship of the observed data. It is necessarily to note that, the probit analysis always assumes that the relationship between number responding (not proportion response) and dose (or concentration) should be normally distributed. Two simple examples are explained in this paper to prove the validity and the consistency of both the proposed mathematical methodology and the concerning computer program. [ABSTRACT FROM AUTHOR]

Artificial intelligence (AI) has permeated all human activities, bringing about significant changes and creating new scientific and ethical challenges. The field of education could not be an exception to this development. OpenAI's unveiling of ChatGPT, their large language model (LLM), has sparked significant interest in the potential applications of this technology in education. This paper aims to contribute to the ongoing discussion on the role of AI in education and its potential implications for the future of learning by exploring how LLMs could be utilized in the teaching of mathematics in higher education and how they compare to the currently widely used computer algebra systems (CAS) and other mathematical tools. It argues that these innovative tools have the potential to provide functional and pedagogical opportunities that may influence changes in curriculum and assessment approaches. [ABSTRACT FROM AUTHOR]

Distance learning is very challenging for both teachers and students. Technology can help educators in combined teaching, which means combining traditional educational methods with active learning. The Halomda educational platform provides improving students' active learning due to better students' engagement. This enhances students' performance as well as the ability to solve mathematics problems. In this paper, we share our experience of how using the Halomda system for combined teaching in the "differential equations" course significantly improves student learning outcomes.

Understanding children's attitudes towards mathematics provides insights into their lived mathematical experience and engagement. Despite the considerable amount of research into students' attitudes toward mathematics, limited research has been conducted into young children's attitudes toward mathematics (YCATM). Within this limited research, investigating YCATM has certain challenges. From a methodological perspective, limitations exist regarding the type of research techniques that can be employed to study the nuances of the issue. The foci of this paper are to present and evaluate a methodological approach that used children's drawings (N = 106) and interview responses as the primary sources of data. Findings indicate that the strategy of "Draw yourself doing mathematics", when used with other research methods, generated rich attitudinal data in the form of personal stories about YCATM.

Steganography is used to hide the occurrence of communication. Discovering and rendering useless such covert message is an art of steganalysis. The importance of techniques that can reliably detect the presence of secret messages in images is increasing as images can hide a large amount of malicious code that could be activated by a small Trojan horse type of virus and also for tracking criminal activities over Internet. This paper presents an improved blind steganalysis technique. The proposed algorithm reduces the initial-bias, and estimates the LSB embedding message ratios by constructing equations with the statistics of difference image histogram. Experimental results show that this algorithm is more accurate and reliable than the conventional difference image histogram method. It outperforms other powerful steganalysis approaches for embedded ratio greater than 40% and comparable with RS steganalysis technique for shorter hidden message length. [ABSTRACT FROM AUTHOR]

This paper reports on a large clinical study with 193 children (Grades 3-6) who interacted with 12 digital math games during clinical interviews. Children completed a pretest interacted with the digital math games, completed a posttest, and answered questions about their interactions with the games. During the interviews, researchers used two video perspectives to capture children's interactions and onscreen gestures. Mixed methods were employed to analyze pretest and posttest data and to examine how the design features in each digital game afforded learning opportunities for children. The resuits showed that children exhibited different levels of awareness of the design features. some features helped or hindered different children, and children who were able to connect the digital games with the mathematics in the games exhibited higher learning gains.

GAMIFICATION ,MATHEMATICS teachers ,CONCEPT learning - Abstract
Our paper advocates the preparation of future mathematics teachers for the use of game-based learning and gamification technologies. For this purpose, we created a university course that is dedicated to familiarizing the students with basic concepts of game-based learning and gamification and to conveying direct experience with their use. We support the concept and activities in this course by the positive results of the research on the opinions of 115 students. We hope that the positive results and our description of the course will be an inspiration for the broader incorporation of game-based learning and gamification technologies into the training of future mathematics teachers. Limitations of our research are the research sample, we investigated students' reactions only at the author's home university. Therefore, in the future, the research could be done with a broader sample and studying more in detail the students' beliefs related to game-based learning and gamification before and after the course to get a better view of their development.

AUTONOMOUS vehicles ,LANE changing ,INTELLIGENT transportation systems ,MATHEMATICS - Abstract
In the process of autonomous vehicle motion planning and to create comfort for vehicle occupants, factors that must be considered are the vehicle's safety features and the road's slipperiness and smoothness. In this paper, we build a mathematical model based on the combination of a genetic algorithm and a neural network to offer lane‐change solutions of autonomous vehicles, focusing on human vehicle control skills. Traditional moving planning methods often use vehicle kinematic and dynamic constraints when creating lane‐change trajectories for autonomous vehicles. When comparing this generated trajectory with a man‐generated moving trajectory, however, there is in fact a significant difference. Therefore, to draw the optimal factors from the actual driver's lane‐change operations, the solution in this paper builds the training data set for the moving planning process with lane change operation by humans with optimal elements. The simulation results are performed in a MATLAB simulation environment to demonstrate that the proposed solution operates effectively with optimal points such as operator maneuvers and improved comfort for passengers as well as creating a smooth and slippery lane‐change trajectory.

Many studies use instructional designs that include two or more artifacts (digital manipulatives, tables, graphs) to support students' development of reasoning about covarying quantities. While students' forms of covariational reasoning and the designs are often the focus of these studies, the way students' interactions and transitions between artifacts shape their actions and thinking is often neglected. By examining the transitions that students make between artifacts as they construct and reorganize their reasoning, our study aimed to justify claims made by various studies about the nature of the synergy of artifacts. In this paper, we present data from a design experiment with a pair of sixth-grade students to discuss how their transitions between artifacts provided a constructive space for them to reason about covarying quantities in graphs.

30. The matter of math: Guiding the blind to touch the Pythagorean theorem.

Due, Brian L.
- Abstract
Science teaching relies heavily on visual illustrations and visually organized assignments as methods of teaching and proving concepts like the Pythagorean theorem. As Visually Impaired Persons (VIPs) cannot see, they derive no benefit from the use of such illustrations alone. Often, material objects are used to help VIPs understand mathematical concepts by means of tactile and haptic perception. In this paper, I will show the practices employed in the pursuit of transforming a visually available material object into something of specific scientific relevance for tactile and haptic exploration. This article thus emphasizes the matter – in the original sense of materiality – of math. Based on video-recorded data, this paper provides an in-depth interactional analysis of a single case in which a VIP engages in a mathematics learning situation with an assistant. This research is based on and contributes to ethnomethodology and conversation analysis by critically examining how objects are used to teach VIPs in math classes. The research has implications for a broadened understanding of how learning mathematics is not just a matter of logics, verbal descriptions or the visual analysis of charts and diagrams, but can also inherently involve the tangible materiality of mathematical representations.

The objective of this paper is not to present all of the findings related to the posed question, but to focus on discussing the methodology employed (i.e. Foucauldian Discourse Analysis), which is relatively novel for analyzing textbooks in mathematics education. One finding will be presented to highlight how the methodology employed can contribute to the field helping to uncover patterns not found using well established deductive frameworks. This methodological discussion is meant to provide an example of how using different methodologies can help to investigate issues in the field and problematize taken for granted norms against a new horizon to embrace the sociopolitical turn.

This paper aims at using a Use-Modify-Create approach to explore students' mathematical problem solving by means of computational thinking (CT) and programming activities. The data collection method is participant observation, in which the researcher also has the role as teacher, guiding the group activities. In our study, two groups of students at the undergraduate level solving a mathematical task. The main finding of the study shows that the progression through the Use-Modify-Create continuum did not work as expected and that the connections between mathematical thinking, computational thinking, and programming proved difficult for the students. Conclusions so far are drawn from the study to promote mathematical problem solving by means of computational thinking and programming in a Use-Modify-Create context. [ABSTRACT FROM AUTHOR]

So far, many ways have been provided to solve Multiple-Criteria Decision-Making(MCDM)problems with interval numbers. Most of these methods rank the alternatives according to two criteria, that is, being close to the Positive Ideal Solution (PIS)and far away from the Negative Ideal Solution(NIS). In this paper, a method is presented for solving MCDM problems with interval numbers, such that being close to PIS and being away from NIS have the same effect in alternative ranking. In the proposed method, the first PIS and NIS are determined as interval numbers and distance of each alternative from PIS and NIS is calculated by extension of Euclidean distance.

Northern Norway's population comprises many different cultural groups. According to the Norwegian Education Act, education must give students insight into and a firm foundation in history and culture. This paper aims to present a proposal for how to start working with the creation of local rural mathematics curricula for which Sámi culture in particular, and Northern Norwegian culture in general, is the basis and foundation. It examines three activities that are examples of intangible cultural heritage from different non-urban Northern Norwegian cultures: i) Sámi traditional measuring, ii) fishermen's traditional navigation at sea and iii) ruvden (a Sámi way of braiding). The activities are analysed with respect to the framework cultural symmetry, which was developed in research in Māori mathematics education. The analysis shows that the three activities are of great significance to local cultural reasoning to such an extent that they should be included in local rural mathematics education. Each of the three activities provides opportunities for developing a culture-based mathematics teaching that values the language and culture in which the activities are embedded. We conclude that cultural symmetry seems to function as a tool for developing a Sámi mathematics curriculum. [ABSTRACT FROM AUTHOR]

DILEMMA ,TEACHER development ,MATHEMATICS education ,MATHEMATICS - Abstract
The research reported in this paper analyses teaching dilemmas experienced by four in-service teachers in the context of a reform-oriented teaching approach for primary mathematics called Developmental Education in Mathematics (DEM). The findings exemplify three teaching dilemmas: Whether to tell students how to solve a challenging task; what to do when students are bored with an important task; and trying to keep the pace of the lesson while supporting all students in the classroom. Importantly, the origins of these dilemmas were found to lie in internal tensions between the components of the DEM system, which the teachers had implemented. Finally, the implications for development of curricular material, implementation of reform-oriented teaching approaches, and the professional development of teachers are discussed.

One essential goal of mathematics teaching is to develop the habit of mind and the ability to look for and recognize structures, to probe into and act upon structures, and to reason and justify in terms of general structures. Framed by the five practices for orchestrating productive mathematics discussions (Smith & Stein, 2011), this paper uses the Horse Rider problem as an example to illustrate how teachers can nurture student structural thinking through careful sequencing of mathematical tasks.

In this paper, we address the weighted multi-objective re-entrant owshop scheduling problem considering release dates in order to minimize makespan, total completion time, total tardiness, maximum idle time, and number of tardy jobs. Each job is taken into account with deterministic processing times, and release dates. The flow-shop comprised of two workshops in whose jobs are entered to the main workshop and after the first part of the processing, they are transferred to the second workshop and after this stage, the jobs are returned to the main workshop for the last part of the processing. We model the problem by a new mixed integer programming based on formulating sum of idle time as a new concept. Moreover, a hybrid evolutionary algorithm is proposed based on some dispatching rules, ant colony optimization, and genetic algorithm. The performance of the proposed algorithm on some test instances is compared to the mixed integer linear programming model as well as the state-of-the-art algorithms called genetic algorithm, tabu search, bio-geography based optimization, and artificial bee colony. The computational experiments show that our proposed approach outperforms other algorithms and the results indicate efficiency and capability of the proposed algorithm in comparison with the traditional algorithms.

This paper reports on a design oriented study conducted in close collaboration between two researchers and three preschool teachers. Within this study, a play-based interview script was designed in accordance with theoretically driven principles. Based on this script, the preschool teachers conducted interviews with children from three preschools five times over four semesters. The focus of this paper is methodological, aiming to show how sensitive divergence in these play-based interviews lead to a strengthened research quality. Of importance is that this quality improving divergence would not have been realized without the close collaboration between researchers and preschool teachers. [ABSTRACT FROM AUTHOR]

Researchers have been paying attention to the convergence of technologies for it can result in improving human behaviour, including student's learning and teacher's instruction. The present paper intends to describe the different types of convergence of technologies in the classroom in general and the mathematics classroom in particular, focusing on the convergence of two types of them: convergence of the learner with the technological tools and convergence of the teacher with those tools. This focus is concerned with two instrumental frameworks: the instrumental genesis and the instrumental orchestration. The paper discusses the foundations of these two theoretical frameworks, the components of the frameworks and their educational uses as tools for analysing learners' and teachers' convergences with technological tools. Researchers assert that the two frameworks have contributed to the understanding of convergence of the learner and the teacher with technological tools, pointing, at the same time, at the need to extend these frameworks or combine them with other frameworks in order to understand the different aspects of this convergence.

In this paper, we investigate adolescent students' ethical mathematics awareness as they reason through interview tasks that provoke them to make a decision based upon the results of data analytics. Drawing on multiple resources, including ethical principles from numerous STEM and business disciplines, we introduce an analytic framework for documenting the ethical mathematics awareness of adolescent students. Our findings indicate that 1) students justify their decision using a variety of ethical principles, and 2) half the students' decisions benefitted their hypothetical employer and half protected society. We conclude the paper with a discussion of implications for designing future instruction to support students' growth in ethical mathematics awareness. [ABSTRACT FROM AUTHOR]

The research described in this paper addresses the question of how school mathematics and mathematics teacher education can be reframed through critical and culturally responsive pedagogies. By analysing the perspectives offered through the research fields of Ethnomathematics (EM), Critical Mathematics (CM), Indigenous Education (IE), Language Diversity (LD) and Equity-based (E-b) approaches, the research works toward a new (disruptive) form of culturally responsive pedagogy (CRdP). As discussed here, CRdP is pedagogically informed by the EM-CM-IE-LD-E-b collective; it is theoretically informed by Nancy Fraser's three-dimensional approach to social justice and participatory parity; and it is methodologically informed by discourse analysis. That is, this paper explores the methodological innovation involved in operationalizing a form of discourse analysis which draws on Nancy Fraser's three-dimensional framework for social justice (distribution, recognition, and representation) to create a Fraser-framed lens through which to view scholarly texts in mathematics/teacher education. While the research is motivated by pedagogical concerns, and on tracing the dialogue between theory/methodology and practice/pedagogy, these concerns are located in the social, political, cultural, and economic insights that the pedagogic actions of CRdP offer to the fields of mathematics (and) teacher education.

In this paper, we explore the ways in which learning more about research on students' experiences in mathematics classrooms has the potential to transform the work we do with teachers in teacher preparation, professional development, and research settings. We focus in particular on questions of student access to and participation in mathematics and highlight studies of the racialized and gendered experiences of students and the connections between these experiences and broader narratives about race, gender, and ability/disability. We conclude with questions and possibilities raised by these studies for our individual and collective efforts to support and understand teacher learning and changes in teacher practice.

Language is organic, innate and ubiquitous. It is the skill that connects everything. Humans try to explore and express themselves through language. The nature and components of language have been humans' preoccupation for a long time. As a corollary, mathematics is also a medium through which humans try to make sense of their world and also express themselves. Humans have remained fascinated by the shapes in nature, and they constantly try to explore and express the world in mathematics. I think that both language and mathematics are inherent behaviors that humans possess and exhibit. As I tried to learn mathematics, I was inevitably struck by the features that overlap and run parallel in both the subjects - mathematics and language. This paper is more about my little understanding of both the subjects. [ABSTRACT FROM AUTHOR]

The importance of computational thinking (CT) as a 21st-century skill for future generations has been a key consideration in the reforms of many national and regional educational systems. Much attention has been paid to integrating CT into the traditional subject classrooms. This paper describes a scoping review of learning tools for integrating CT and mathematics in current empirical studies published from 2015 to 2021. The review showed that most of the studies implemented CT-intensive Math-connected integration. Five major types of CT tools had been identified, i.e., digital tangibles, apps and games, programming languages, formative or summative assessments, and other technological tools. In many instances, the tools also provide functions of assessment of CT skills. The most assessed CT competencies were including algorithms and algorithmic thinking, abstraction, testing and debugging, loops, and sequences. Geometry and Measurement was the most assessed mathematics topic. Our scoping review is beneficial in the investigation of the literature on CT and mathematics education, as well as guides those who are interested in developing curriculum, programs, or assessments that involve the integration of CT and mathematics.

CAREER development ,MATHEMATICS ,MATHEMATICS education ,TEACHERS - Abstract
In response to urgent calls for teaching that is culturally affirming, scholars have developed a myriad of images of culturally sustaining (and related) pedagogies (CSPs). However, for maths teachers, CSPs remain elusive, in part because these images are typically content-neutral and their applicability to practice opaque. In this paper, I synthesize research to help conceptualize and clarify what CSPs may look like specifically in mathematics classrooms. I offer a framework for CSPs in mathematics comprised of four dimensions: (1) anti-assimilationism, (2) strengths-based teaching, (3) power and justice, and (4) affirming identities.

Airy and Bessel functions are one of the most popular and important special functions in various branches of physics, mathematics, and engineering. An observation to their behavior for the real argument suggest that they are related. This relation was studied earlier, but were accompanied by a number of assumptions, approximations, and sometimes even misconceptions. This motivated us to develop a fresh and transparent method to establish these relations. As the continuation of our study of the two papers published in resonance already, here we have used the general asymptotic series and the convergent series of these functions and thereby developed two new methods which throw light on the subtle interrelationships between these functions. Numerical evidences of our claims are provided for better clarity and understanding. [ABSTRACT FROM AUTHOR]

Integral Calculus II is a second-year undergraduate course offered by the Department of Pure and Applied Mathematics at Maseno University. It is one of the 20 foundational courses with a high enrolment of about 800 students drawn from the school of Mathematics, Education, Science, and Business. Because of the large number of enrollments in these foundational courses, and the small number of teaching staff, instructors face challenges in providing immediate personalized feedback that can guide learning. Systems for Teaching and Assessment which use Computer Algebra Kernerl, STACK, a computer-aided assessment plug-in that provides a sophisticated assessment in mathematics-related disciplines, was used to deploy Continuous Assessment Tests (CAT) in the course for 370 students. This paper reports on the findings of the course based on a comparison between student test scores in STACK and in the final course exam. [ABSTRACT FROM AUTHOR]
