Abstract

Development of Grade 10^th Students’ Application Abilities about Chemical ReactionUsing Context-based Learning

This research aimed to study grade 10^thstudents’ application abilities about chemical reaction using context-based learning (CBL). Studied group was 30 grade 10^thstudents in science and mathematics program. The research was conducted by using 6 plans of context-based learning in chemical reactions lessons. After learning with these plans, students were assessed by the test for application abilities consisting of 5 open-ended questions, which cover 5 types of application abilities. The results have shown that all of the students can determine examples of the chemical concepts from their everyday life (type 1). Secondly, 93.33% of the students have the ability to understand principles of science and technologies in chemistry about chemical reactions (type 3). Thirdly, 86.67% of the students have the ability to use concepts and science process skills of chemical reactions to solve problems (type 2). The types which the lowest percent of the hold by students are the ability to understand and evaluate news related to the advancement of science in chemical reactions from mass media (type 4), and the ability to make a decision about health, nutrition and lifestyle based on science knowledge, understandings and concepts rather than based on word of mount or tempers (type 5) in which 80% of the students showing to have each ability type.
