The analysis of student's laboratory work skill on chemical equilibrium topic

Abstract

Assessing the student's performance during practicum is important to measure the student's skill during practices. This study aims to analyze student's scientific skills during the Chemical Equilibrium practicum. For this research, researchers used one shot case study design of experimental methods. The data were obtained through the description of students activities during the practical training and the analysis of performance assessment. The result showed that 100% of the students are well-skilled at using spray bottles, dropping plates, reading the universally-indicated pH trajectory, and cleaning the equipment. 93,75% of the students excelled the skills of using pipettes, measuring the volume of the solution, and stirring the solution. The students are less-skilled at shifting the solution and diluting the solution, with only 68,75% of the students passed the expected activities. The skill of choosing and disposing the waste of the practical training has the lowest number of students excelled, with only 50% of them passed the expected standard. The student's scientific skill needs an upgrade especially on the skill of choosing and disposing the waste.
