ANALISIS KEPERLUAN PENGGUNAAN KERANGKA TIGA ARAS PEMBELAJARAN KIMIA DALAM PENGAJARAN MODEL ATOM BOHR

Abstract

This paper discusses a needs analysis conducted to consider the use of the three learning levels of chemistry (macroscopic, submicroscopic and symbolic) for teaching the topic Bohr’s Atomic Model (BAM). This study consists of two parts; (1) to identify the comparative and normative needs of students on the topic, (2) to characterize the teaching and learning of BAM according to three learning levels of chemistry based on analysis of relevant course documents. The second part will determine whether the current instruction can be improved by using the three learning levels of chemistry. This study involved 59 students from a one-year matriculation program at a matriculation college. Normative need was determined using the Achievement Test in BAM. It was found that the level of students’ achievement is moderate and low. Therefore, there is a need to improve the students’ achievement to a higher level. Document analysis showed that teaching and learning in tutorial classes do not show characteristics of the three learning levels of chemistry and emphasis was mainly on the symbolic and submicroscopic levels. This makes the topic Bohr’s Atomic Model difficult to understand and encourages rote learning. In summary, steps to improve the teaching and learning of this topic are proposed.
