Succeed or failed: Diagnostic of student's ability to passed basic learning material on liquid pressure, respiratory system and its application based on integrated sciences test in school

Abstract

This research performed to analyze student's ability to mastering the liquid pressure and body breathing system materials on integrated science learning. Both of the materials in integrated learning include blood pressure, diffusion of respiratory events, osmotic pressure, fluid pressure at a different depth, buoyancy, and capillarity expressed in a specific test. The study covered 144 students in the Integrated Islamic Junior High School. We organized a student's ability assessment based on midterm semester exam conducted in March 2018. Data analysis applied by Rasch modeling. The results of this study indicated that students have difficulty in understanding the pressure on liquids, notably in bringing water process from root to leaf (capillarity on plants). Conversely, students are qualified to figure out the operation of the mucous membrane in the nasal cavity in the body respiratory system. Other interesting points discussed in this article are quality of the test related to measure students' ability and traces of student misconceptions in learning materials on integrated science. It is prerequisite for teachers to promote the quality of learning in the integrated science, and to develop a quality test for student in the future.
