Effectiveness of Activities based on 5E Model of Constructivist Approach on Tenth-Grade Students� Understanding of Covalent and Ionic Compounds

Dr. Uzma Siddiqui

Abstract :

<p>&lt;p&gt;&amp;nbsp;This paper investigated the effects of teaching one of the most fundamental concepts of Chemistry &amp;lsquo;Covalent and Ionic Compounds&amp;rsquo; using Traditional Instruction (TI) and 5E Model of Constructivist Approach (MCA) on students&amp;rsquo; achievement in Chemistry. A total of 60 tenth-grade students participated in this pretest-posttest control group quasi-experimental study. Control Group (n = 30) was taught by TI, whereas the two Experimental Groups EG (n = 30) was subjected to MCA. An analysis of covariance on Chemistry achievement posttest scores with students&amp;rsquo; pretest scores as the covariate showed that MCA was more effective in enhancing the students&amp;rsquo; achievement in Chemistry than TI. It is, therefore, suggested 5E model is a good supplementary method of teaching Chemistry.&lt;/p&gt;</p>
