Internal Visualization challenges concerning sub-microscopic particles in chemistry often result in some difficulties in learning the change of state of matter. Therefore, this study aims at developing an augmented reality ProCAR module that utilizes a project-based learning approach to facilitate learning changes of matter. This study employs ADDIE (Analysis, Design, Development, Implementation and Evaluation) instructional design model. The quality of the module was evaluated by a group of 5 Chemistry teacher-educator experts of Universiti Teknologi Malaysia to identify the suitability of the module. Inter-rater reliability (IRR) percentages were determined and the feedback was analyzed based on thematic analysis. The result shows that 100% of its learning objectives, Content, Usability, and Assessment and 75% of its performances were good and reliable all having IRR value 75% and above. Such revealed that AR Module is potentially effective for the teaching phase change to Secondary school students. Recommendations for future studies were highlighted
<p class="0abstract">Chemistry is branch of science that is different because of chemical representations. The chemical representation made students assumed that chemistry is difficult. Students must master chemical representation to be able understand chemistry deeply. Besides, science process skills are crucial skills in learning chemistry, however, the students’ science process skills are rare to be involved. Chemical representation and science process skills have relationship each other. Nowadays, it was still difficult to find module could be used either face-to-face learning or online learning. Therefore, this study aimed to develop valid module integrated chemical representation and science process skills, and can be used in face-to-face learning and online learning (dual mode module) and to investigate teachers’ response about module. The research design used was ADDIE, data collected by using online validation form that was given to 6 validators to assess module based on suitability content, potential effectiveness, and overall satisfaction. To investigate chemistry teachers’ response to module, the online questionnaire given to teachers and it was further analyzed using percentage and compare to criteria of validity and criteria of response user. Th result found that module developed is valid with suitability content is 90.7%, potential effectiveness is 92%, and overall satisfaction is 92.5%. The chemistry teachers’ response showed that this module is very good criteria (92.36%). Therefore, dual mode module hopefully would be used in learning chemistry as media in face-to-face learning and online learning and also support chemical representation and science process skills among students. </p>
<span lang="EN-US">The Aborigines of Malaysia portray limited knowledge of domestic wastes conversion into homemade fertilizer for crops which is also needed to facilitate proper home hygiene. Therefore, this study developed a Home fertilizer teaching module that applies 5E model to educate the knowledge deficient Aborigine People. The study used a qualitative research approach through the collection of open-ended data and analyzed based on themes. The research procedure was divided into: i) Development of the Home fertilizer module; and ii) Validation of the Home fertilizer module. Validation of the module was done by eight experts in teaching science and mathematics who were selected based on the purposive sampling technique according to the study aim. An open-ended questionnaire that contains ten items about the suitability of the module to be implemented among the Aborigines community, the content of the module, and involvement of STEM learning was the instrument of the study. Results showed that the content of the module is easy to understand with a clear objective and also stimulates science, technology, engineering, and mathematics (STEM) learning. Also, the module was considered a sanitary STEM module that is suitable for educating the Aborigine people on domestic waste conversion into homemade fertilizer and maintaining a cleaner environment. </span>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
