Abstract

This study aimed to investigate students’ learning achievement and retention of acid base volumetric titration by using four inquiry-based learning These experiments included: 1) acidimetri 2) alkalimetri, 3) complexometri, 4) argentometri. Twenty eight students at Open University of Banjarmasin during the first academic semester of 2012 were purposively selected as participants. The data collected, included students’ learning achievement test scores of acid base titration, learning retention scores 30 days after the implementation, and a survey of student satisfaction in learning inquiry-based 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 animals 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, questionnaire, 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.
