Abstract

Learning tools have been developed through lesson plans, worksheets based on learning-guided discovery, and assessment instruments to improve critical thinking skills on the sub-subject factors that affect the reaction rate. The stages carried out in the production process of the two types of learning devices are defining, planning, and development, which are the three stages of the four stages of the 4D model. Two lecturers and one teacher validate the quality of the developed learning tools. Based on the results of data analysis, the lesson plan as a whole has good quality, the student worksheet is in the very good category, and the instrument for assessing students' chemical critical thinking skills has a high category of validity. Based on the integration of learning model guided discovery, the lesson plan and student worksheet have very good quality, and the integration of critical thinking skills in the assessment instrument is very good.

Abstract

Characteristic of Chemistry learning which is integrated with etnochemistry is the existing of local culture wisdom aspects as a learning media, as a learning source, or as a learning method to comprehend chemistry concepts. This descriptive research aims to analyse the relevance of local culture wisdom with Analytical Chemistry subject which is integrated with etnochemistry in production of salt in order to develop learning instruments based on Problem Based Learning (PBL) learning method. The objects of the research are local culture wisdom in production of table salt (in Pijot village, Sub-district of Keruak, Distric of East Lombok, West Nusa Tenggara Province, Indonesia) and Analytical Chemistry subject. Data is collected from documents and interview and then being analysed descriptively. The results showed that (1) There is a relevancy of local culture wisdom element in production of salt with any topic in Analytical Chemistry subject, (2) Lecture instruments of Analytical Chemistry subject which is integrated with etnochemistry could be developed by including sea water, salt, and bittern water as learning media in class lecture and in practical work in laboratory, and salt crystallization process as learning source, (3) Lecture instruments of Analytical Chemistry subject which is integrated with etnochemistry based on PBL method could be developed by including real problem in society as a way to improve quality of salt so it appropriate with SNI standard. (SNI = Standar Nasional Indonesia: Indonesia National Standard).
