Abstract
<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>
Highlights
1.1 BackgroundChemistry is one branch of science that is related to substances which included composition, structure, properties, changes, energy, and dynamics [1]
The module is learning media that can be used by students independently with or without teacher guidance and by using module students are able to arrange their learning, it will help teachers to assess the level of content that must be mastered by students [39]
Dual mode module is developed to solve problem existed in learning chemistry especially on topic rate of reaction
Summary
1.1 BackgroundChemistry is one branch of science that is related to substances which included composition, structure, properties, changes, energy, and dynamics [1]. Macroscopic, and symbolic [2]. The three aspects are related to each other like a triangle in which chemical iJIM ‒ Vol 15, No 18, 2021 phenomena can be seen through these levels. In terms of macroscopic level, the chemical phenomena are shown through the experiment or in other words it includes the things that can be clearly seen with naked eyes. In terms of microscopic, it shows phenomena that cannot be observed by naked eyes, it needs tools to see what happens in terms of particles such as the interaction between particles, the chemical bond, and to know the movement of particles. The integration of microscopic, macroscopic, and symbolic representations causes difficulty to teachers in conducting learning and teaching chemistry because the teachers need to fully visualize and conceptualize it
