Development of generic science skills on determination of mineral chloride levels in packed drink using inquiry guided laboratory

Abstract

This study aims to describe learning activities, to analyze students ‘ability to complete worksheets, and to analyze students’ generic science skills during the determination of based mineral water chloride content.The Mohr method is an argentometric titration that can be applied to the determination of the mineral water chloride content. Inquiry Guided Laboratory can be used as an alternative learning model to develop generic science skills of students. IGL adopt learning cycle stages consisting of orientation, exploration, concept discovery, application and finality. Subjects of this study are 57 student of Chemistry Analytical students. The research design used is classroom research. The research instrument consisted of instructional learning observation sheet, psychomotor assessment sheet, worksheet, and report and presentation report sheet that emphasized on generic science skill assessment. The result of the research shows that the learning is done very well, with the average of the implementation percentage is 88,27%. The students’ ability to complete the worksheet earns an average of 87.92. Generic science skills developed through learning scored an average of 88.1. The generic science skills generator developed scores above 80, only symbolic language indicators scored 76.6. It shows that inquiry guided laboratory can developed generic science skill on determination of mineral chloride levels in packed drink.
