Cano, Junar S. – International Society for Technology, Education, and Science, 2021
The essence of Genetics lies in the understanding of the concepts of Central Dogma of Molecular Biology. Although these ideas are fundamental to the field, they are notoriously difficult to understand and visualize. While simulation-based instructional materials are found to improve the teaching-learning process in science education, little has…

Khali, Muhammad; Khalil, Umair; ul Haq, Zahoor – International Electronic Journal of Mathematics Education, 2019
One of the reasons to use technology in education is to visualize and explore the insight of mathematics with optimum possibilities. Geogebra gives visual meaning to symbolic ideas along with optimum dynamic possibilities. The purpose of this experimental study was to know about the potential effect of dynamic geometry software on diverse…

Dori, Yehudit Judy; Kaberman, Zvia – Instructional Science: An International Journal of the Learning Sciences, 2012
Much knowledge in chemistry exists at a molecular level, inaccessible to direct perception. Chemistry instruction should therefore include multiple visual representations, such as molecular models and symbols. This study describes the implementation and assessment of a learning unit designed for 12th grade chemistry honors students. The organic…

Stott, Angela; Case, Jennifer M. – African Journal of Research in Mathematics, Science and Technology Education, 2014
Electronic tutors able to respond appropriately to a user's input have been shown to be effective in improving learning in a number of contexts. This study extends this research into the context of conceptual change during in-service science teacher workshops. Quantitative data were collected from 1,049 South African grade 12 physical sciences…

Widder, Mirela; Gorsky, Paul – Journal of Computers in Mathematics and Science Teaching, 2013
In schools, learning spatial geometry is usually dependent upon a student's ability to visualize three dimensional geometric configurations from two dimensional drawings. Such a process, however, often creates visual obstacles which are unique to spatial geometry. Useful software programs which realistically depict three dimensional geometric…

Ross, John A.; Bruce, Catherine D.; Sibbald, Timothy M. – Teaching Mathematics and Its Applications: An International Journal of the IMA, 2011
Studies incorporating technology into the teaching of trigonometry, although sparse, have demonstrated positive effects on student achievement. The optimal sequence for integrating technology with teacher-led mathematics instruction has not been determined. Our research investigated whether technology has a greater impact on student achievement…

Gerny, Marianne; Alpers, Burkhard – International Journal of Computers for Mathematical Learning, 2004
In this article we describe a mathematical microworld for investigating car motion on a racing course and its use with a group of grade 12 students. The microworld is concerned with the mathematical construction of courses and functions which describe car motion. It is implemented in the computer algebra system, Maple[R], which provides the means…
