Dyer, Elizabeth B.; Parr, Erika David; Machaka, Nessrine; Krist, Christina – North American Chapter of the International Group for the Psychology of Mathematics Education, 2021
This study examines how joint exploration is established and maintained among students and the teacher in secondary mathematics classrooms. We use the theoretical perspective of positioning to conceptualize joint exploration as involving the negotiation and coordination among participants to position students with epistemic agency and authority.…

von Davier, Matthias; Tyack, Lillian; Khorramdel, Lale – Educational and Psychological Measurement, 2023
Automated scoring of free drawings or images as responses has yet to be used in large-scale assessments of student achievement. In this study, we propose artificial neural networks to classify these types of graphical responses from a TIMSS 2019 item. We are comparing classification accuracy of convolutional and feed-forward approaches. Our…

Jayashanka, Rangana; Hettiarachchi, E.; Hewagamage, K. P. – Electronic Journal of e-Learning, 2022
During the COVID-19 pandemic period, all the Sri Lankan universities delivered lectures in fully online mode using Virtual Learning Environments. In fully online mode, students cannot track their performance level, their progress in the course, and their performances compared to the rest of the class. This paper presents research work conducted at…

Li, Jiawei; Supraja, S.; Qiu, Wei; Khong, Andy W. H. – International Educational Data Mining Society, 2022
Academic grades in assessments are predicted to determine if a student is at risk of failing a course. Sequential models or graph neural networks that have been employed for grade prediction do not consider relationships between course descriptions. We propose the use of text mining to extract semantic, syntactic, and frequency-based features from…

Janney, Benjamin A.; Sobotka, Alex J.; Kidd, Aaron E. – Clearing House: A Journal of Educational Strategies, Issues and Ideas, 2022
Despite holding wide-ranging experiences with constant velocity and non-zero acceleration, students wrestling with physical science concepts struggle to demarcate the two distinct characteristics of motion. In fact, this prior experience and loose familiarity with associated terminology often act as an obstacle toward a deep and robust…

Langendorf, Ronja; Schneider, Susanne; Klein, Pascal – Physical Review Physics Education Research, 2022
The Hertzsprung-Russell diagram (HRD) is a fundamental representation in stellar physics. It contains information about key properties of stars and allows inferences about stellar evolution. The use of the HRD is an important disciplinary activity in astrophysics. For example, it is particularly important to have a graphical understanding of the…

Roncevic, Tamara N.; Cuk, Željka Ð.; Rodic, Dušica D.; Segedinac, Mirjana D.; Horvat, Saša A. – Journal of Baltic Science Education, 2019
This research considered students' abilities to read images about dispersed systems, taken from the chemistry textbook. 103 high school students (37 males, 63 females, and 3 unknown) from the school "Svetozar Markovic" in Novi Sad, Republic of Serbia, were included as the research participants. Students' abilities to suggest the titles…

Yan, Yaw Kai; Subramaniam, R. – Chemistry Education Research and Practice, 2018
This study focused on grade 12 students' understanding of reaction kinetics. A 4-tier diagnostic instrument was developed for this purpose and administered to 137 students in the main study. Findings showed that reaction kinetics is a difficult topic for these students, with a total of 25 alternative conceptions (ACs) being uncovered. Except for…

Novak, Igor – Journal of Chemical Education, 2018
Chemical equilibrium is one of the most important concepts in chemistry. The changes in properties of the chemical system at equilibrium induced by variations in pressure, volume, temperature, and concentration are always included in classroom teaching and discussions. This work introduces a novel, geometrical approach to understanding the…

Johnson, Heather Lynn; McClintock, Evan – Educational Studies in Mathematics, 2018
In this design experiment study, we investigated the problem: What conditions might foster students' discernment of a critical aspect--variation in unidirectional change (e.g., discerning a "decreasing" increase)? At a public middle school in a large US city, we led a sequence of three days of whole class lessons, followed by task-based,…

Balasubramaniam, Dharini; Hinrichs, Uta; Noreika, Martynas; Macindoe, Alasdair – New Directions in the Teaching of Physical Sciences, 2018
Traditional module delivery in higher education often follows a linear structure, which is not always conducive to understanding concepts and the many possible relationships between them. In this paper we introduce an online visual interactive learning resource called ViLO designed to address this problem. We describe the principles guiding the…

Prieto, L. P.; Sharma, K.; Kidzinski, L.; Rodríguez-Triana, M. J.; Dillenbourg, P. – Journal of Computer Assisted Learning, 2018
The pedagogical modelling of everyday classroom practice is an interesting kind of evidence, both for educational research and teachers' own professional development. This paper explores the usage of wearable sensors and machine learning techniques to automatically extract orchestration graphs (teaching activities and their social plane over time)…

Cooper, Linda L. – Journal of Statistics Education, 2018
Everyday encounters with graphical representations include a variety of graphs that superficially appear similar due to their use of bars. This article examines students' conceptions and misconceptions regarding the interpretation of variability in histograms, bar graphs, and value bar charts. A multiple choice assessment with brief written…
