Abstract

Chemical concepts are tiered from simple to complex. If misconceptions occur in simple concepts, they can cause misconceptions in complex concepts. The four-tier instrument is a tool for detecting misconceptions. This research aims to develop and describe the validity and reliability of a four-tier instrument on junior secondary-level chemistry concepts. This development research consists of 6 procedures: (1) concept mapping, (2) testing, (3) defining unscientific concepts, (4) developing four-tier instrument prototypes, (5) validating four-tier instrument prototypes, and (6) finalization of four-tier instruments. The developed four-tier instrument consists of 27 questions that measure chemistry concepts at the junior intermediate level. The instrument received an expert validation score of 92.81% with very valid criteria. The test results on 30 samples showed a reliability value based on a Cronbach alpha score of 0.713 with good criteria. The four-tier instrument on lower secondary level chemistry concepts meets the validity and reliability requirements so that it can be used to diagnose misconceptions on lower secondary level chemistry concepts.

Abstract

This research aims to describe the skills of opening and closing lessons when prospective science teacher students practice teaching. This experiment is included in single subject research which is analyzed descriptively-quantitatively for students who will become science teachers and take microteaching courses. A teaching skills assessment rubric was used to obtain data for this research. The results of the study show that 1) the skill of opening lessons for prospective science teacher students is in the good category for each activity, namely the lesson begins with greetings then prepares students to learn, conducts apperception and explores students' initial knowledge, and communicates learning objectives. 2) skills in closing science teacher candidate students' lessons in a good category in reflecting and concluding learning material, giving follow-up directions regarding assignments or learning material for the next meeting, and ending the lesson by giving greetings and the like.
