Development of grade-11 Studentsu understanding about rate of reaction and attitude toward learning chemistry by using context-based learning activities (Thai)

Abstract

The purpose of this research was to investigate grade-11 studentsû understanding about rate
of reaction and attitude toward learning chemistry by using context-based learning activities. It was
a case study of forty one students from a school under the office of Nonthaburi Educational Zone
2 after learning through context-based learning lesson plans in the first semester of the 2009 academic 
year. The results showed that the students who learned through context-based learning activities had
more understanding about rate of reaction. The percentage of studentsû correct understanding about rate
of reaction on pre-test and post-test increased from 27.94 % to 66.57 %, respectively. Moreover,
most of the students held an attitude toward learning chemistry at a high level. Students explained
that they favored context-based learning because it had variety, had novelty, was hands-on and used
various learning media.
