Abstract

This study aims to produce discovery learning-based worksheets on chemical equilibrium material through expert judgment. The method in this study is Research & Development (R&D) with a Four-D development model which is limited to the Develop stage, based on a feasibility test. The subject of this research is student worksheets (LKPD) based on discovery learning on chemical equilibrium material for class XI students of SMA Negeri 1 Kuala Mandor B. Data collection techniques used are measurement techniques and direct communication techniques. The data collection tool is in the form of a LKPD feasibility assessment sheet. The feasibility test was carried out based on the material aspect, namely 92% with a very feasible category, the language aspect was 95.2% with a very feasible category and the design aspect was 95% with a very feasible category. Thus, it can be concluded that the worksheets based on discovery learning on chemical equilibrium materials developed are feasible. for use in learning.

Abstract

The inquiry ability is an ability to obtain information through observation or experimentation to solve a problem by using critical and logical thinking skills which include several stages, namely the stages of formulating problems, formulating hypotheses, analyzing data, and concluding. This study aimed to determine student’s ability to inquire about the salt hydrolysis material at SMAN 8 Pontianak. The type of research used is descriptive research using the case study method. The research subjects were 20 students of class XI science at SMAN 8 Pontianak. The instrument used is an inquiry-ability test in the form of 4 essay questions and interview guidelines as a supporting instrument. The results showed that the average ability to inquire of students was included in the good category. The results of the analysis on each aspect stated that the average student inquiry ability in the aspect of formulating problems obtained a value of 80.6% and was classified as a good category. The aspect of formulating a hypothesis has an average value of 73% with a good category. The aspect of analyzing the data has a value of 55.8% with a fairly good category. While the aspect of formulating conclusions has a value of  60.6% with a fairly good category.
