REVIEW: DIAGNOSTIC TEST AS FORMATIVE TEST IN CHEMICAL LEARNING
The author's article aims to determine the effect of using a diagnostic test as a formative test in improving learning outcomes in chemical materials. The method used is the meta-analysis method by comparing information through several studies of uniform research literature. Students have different learning ability, so the role of the teacher as a facilitator is indispensable. Teachers must know the initial ability of students individually through early assessment activities so that teachers know the ability of students. The information obtained from students can be used as a reference in improving the learning process. The involvement of diagnostic tests as a formative test in chemistry learning is used as early consideration knowledge for the formation of heterogeneous groups, emphasis in learning, and determination of difficulty learning students that can improve student learning outcomes. The use of diagnostic tests as a formative test in chemistry learning can provide an accurate diagnosis of learning difficulties. Based on the analysis of 3 literature, diagnostic tests can improve student learning outcomes through the formation of heterogeneous groups. Learning planning with diagnostic tests as a consideration in the group formation learning resulted in the lowest increase of 26.85% and the highest increase of 38.9%. The comparison increase in student learning outcomes can be observed through the percentage of completeness results before and after the diagnostic test is carried out, which is then carried out by paired statistical tests. Student learning outcomes are seen from the percentage of learning completeness before and after using a diagnostic test which is then processed using a paired sample type statistical test. The test resulted in a significant increase in learning outcomes of 32.583%. This shows that student learning outcomes have increased after using diagnostic tests as a formative test in chemistry learning.
