The effectiveness of guided inquiry-based student worksheets on students’ generic science skills

The generic skill of chemistry is the ability to think and act according to the chemistry obtained. The purpose of this study was to determine the effectiveness of guided inquiry-based student worksheets on students' generic science skills. The effectiveness of learning outcomes is seen in the acquisition of the N-Gain value of learning outcomes. The approach used experiment was using one group pretest-posttest design. The sample consisted of 62 students year eleven from two secondary schools in Banda Aceh, Indonesia. The data were collected through generic science skill observation sheets and learning results test. The results showed that generic science skills of the first school were developed on indicators of direct and indirect observation, logical consistency and logical inference. As for the second school were developed on direct observation indicators, logical consistency, and logic inference. Both schools had generic science skills indicators with good criteria. The value of N-gain learning outcomes of the first school was 0.54 and the second school was 0.47 with the medium category and t-test results were significantly different. Thus, the guided inquiry-based student worksheets effectively could be used as an alternative teaching material on acid-base material practice.
