Probing for Students’ Understanding in Chemistry: Using Multiple Approaches (Part Four: two-tier diagnostic test)

1. Two-tier Diagnostic Test
The other approach can be used to investigate students’ understanding is two-tier diagnostic test which was developed by David F. Treagust. This approach is powerful to encourage students’ analytical thinking on understanding the concepts. In addition, there are varied format of this instrument (Mann & Treagust, 1998), but basically the first tier [...]

The Role of Constructivism in Teaching and Learning Chemistry

Introduction

Constructivism is one of theory of learning which well developed in the recent year and becomes most significant and dominant perspective in science education (Taber, 2006). According to Bodner (1986), constructivist model focus on constructing the knowledge in the learners’ mind. Every student has different experiences, therefore teacher has to be aware that knowledge [...]
