This research aimed to provide solutions for secondary school teachers on physics who were incapable of designing decent stem education for their own learning activity contexts, and experts did not agree that it did not conform to the concept of STEM Education. It was, then, to develop steps on physics STEM Education learning system activity in secondary school education for further...
Students always bring intuitive ideas about physics into classes, which can impact how they learn and how successful they are. To examine what Cambodian students think about projectile motion, we have developed seven open-ended questions and applied to grade 11 before (N=124) and after (N=131) conventional classes. Results revealed several consistent misconceptions, for instance, many students...
With and without physical context, we explored 59 undergraduate students’conceptual and procedural understanding of vector components using both open ended problems and multiple choice items designed based on research instruments used in physics education research. The results showed that a number of students produced errors and revealed alternative conceptions especially when asking to draw...
In higher education, lecturing has been found as the most prevalent teaching format for large classes. Generally, this format tends not to give the effective learning outcomes. Therefore, to support student learning in the large lecture classes, we developed guided notes containing quotations, blank spaces, pictures, and problems. A guided note taking strategy was selected and has been used in...
The objectives of this study were to develop and assess student understanding of measurement and uncertainty. A test has been adapted and translated from the Laboratory Data Analysis Instrument (LDAI) test, consists 20 questions focused on three topics including measures of central tendency, experimental errors and uncertainties, and fitting regression lines. The test were evaluated its...
This research focuses on simulation of the radiation attenuation using a Monte Carlo program called GEANT4. In the simulation, properties and geometries of the shielding system, which are the thickness, shape and element of the shielding material, can be varied. The radiation in gamma rays regime is considered to be emitted from the isotropic radioactive sources that are Cs-137, Co-60 and...
