Abstract

This research described a competence levels of students on learning natural sciencesin elementary school. Specifically, we measure student’s capacity in understanding of energyand weather concepts. This research involved 64 students on elementary school. The data takesfrom class promotion test with consisting multiple choice questions (MCQ) and Essay Test. Dataanalysis was produced using the Partial Credit Model (PCM) Rasch measurement. The RaschPCM specifies that each item has its own scale rating structure, so the two test types can beanalysed simultaneously. The results showed that in general the students had difficulty toconcluding the observation that the motion of the object was influenced by its shape and size;and pointed out of the relation between cloud and weather conditions. On the separate part,students clearly realize how to conserve the energy in everyday life; and interpret the effects ofweather for human life. Furthermore, the MCQ test is problematic than the Essay Test forstudents. The average male student has better ability than the female students to comprehend thelearning materials.
