Improving Students? Science Process Skill and Achievement through Experiential Learning: Biodiesel Production

This study aimed to investigate students learning achievement and retention biodiesel production by using experiential learning These experiments included biodiesel production by using CaO catalyst. Twenty eight students at electric programme, during the fourth academic semester of 2012 were purposively selected as participants. The data collected, included students learning achievement test scores of, learning retention scores 30 days after the implementation, and a survey of student satisfaction in learning experiential learning were analyzed. Pretest-posttest control group design was adopted for this study with two classrooms. Control group was taught by traditional lecture supplemented with readings on aggressive behavior of and other while experimental group was experienced with an intervention with the same period of time (three hours), and with the same contents and the same learning objectives as control group. Experimental skills test, students group poster, questionaire, semi-structured interview, and classroom observation were used to gather data. The results revealed that students experiencing an intervention gained better both aggressive behavior understanding and experimental skills than the tradition
