Development of instructional package with video clips on problem solving steps in mathematics of sixth-grade students in Bhutan

This study developed an instructional package with video clips on problem solving steps in mathematics for sixth-grade students in Bhutan. The instructional package composed of four components: content, lesson process, video, and evaluation. The purposive sampling technique was used for selecting 28 sixth-grade students of Khamdang Lower Secondary School, Trashi Yangtse, eastern Bhutan to study Unit 4: measurement. The success of the instructional package depended on the students' academic achievement and their satisfaction. To measure these, achievement tests were administered before (pre-test) and after (post-test) the experimental phase, and a satisfaction questionnaire was administered one time, after the experimental phase. The achievement test was analyzed using the paired sample t-test, and it revealed that achievement test was statistically significant p(0.000)<0.05. Student satisfaction questionnaire data were analyzed using descriptive statistics (mean and standard deviation) and showed that their satisfaction level was very high. Thus the current study concluded that the instructional package was successful and can be a reliable resource.
