The purpose of the study was to compare the effectiveness of visualization of natural phenomena via computer simulation and manipulations of concrete objects, in a physics laboratory, on the development of students’ inquiry skills in mechanics. A quasi-experimental method that employed the 2 Learning Tools x 2 Time of learning split-plot factorial design was applied in the study. The sample consisted of 54 Grade 11 students from two physics classes of the university preparation section in the Ottawa-Catholic School Board. One class was assigned to interactive computer simulations (treatment) and the other to concrete objects in physics laboratory (control) as learning tools. Both tools were embedded in the general framework of the guided-inquiry cycle approach. The results showed that the interaction effect of the Learning Tools x Time of learning was not statistically significant. However, the results also showed a significant effect on the development of students’ inquiry skills (indicated by the pre- and post-inquiry skills test) regardless of the type of learning tool they had used. The findings suggested that these two strategies are effective in developing students’ inquiry skills in mechanics.

In this study, the use of robotics was explored in a Grade 12 Technical Sciences class, to further understand it as an emerging pedagogy that allows learners to apply creative thinking and produce innovative solutions to problems in Newton’s Second law of motion. The study's conceptual framework was underpinned by constructivism, constructionism and the Cognitive Refinement Instructional Approach (CRIA), which supports the notion that through assimilation and accommodation, Lego Mindstorms robotics tools can be used as manipulatives to develop new knowledge. The learners participating in this mixed-method procedure of enquiry were randomly assigned to an experimental group (n = 21) that took part in the robotics intervention and a control group (n = 21) that continued with conventional extra classes. It was evident in the qualitative results that learner’s knowledge improved regarding the concepts of acceleration and net force, but misconceptions persisted in the concepts of frictional force and tension force. In the analysis of the quantitative results, the independent-samples t-test showed that there was a significant difference in the post-test scores between the control group (M= 3.19, SD= 1.16) and experimental group (M=4.57, SD= 1.43); t(40)= 3.42, p = 0.001. The study found that robotics does have a significant effect on the academic test scores of Technical Sciences learners than the traditional intervention in Newton’s Second Law. The scientific merit and significance of this study will contribute to teaching methods and learning of science in the technical-academic schooling stream. / Dissertation (MEd)--University of Pretoria, 2021. / Science, Mathematics and Technology Education / MEd / Unrestricted

No / Online games require small data of 3D models for low storage costs, quick transmission over the Internet, and efficient geometric processing to achieve real-time performance, and new techniques of facial blendshapes to create natural facial animation. Current geometric modelling and animation techniques involve big data of geometric models and widely applied facial animation using linear interpolation cannot generate natural facial animation and create special facial animation effects. In this paper, we propose a new approach to integrate the strengths of ODE (ordinary differential equation) sweeping surfaces and Newton's second law-based facial blendshapes to create 3D models and their animation with small data, high efficiency, and ability to create special facial effects.
