Abstract

This study reports on the implementing a four-tier test diagnostic instrument on magnetism concept, which has not been defined in the literature. It is an improved understanding of the two-tier test matters. The four-tier diagnostic test was focused on electricity concept. It was measured to 20 elementary school students. They were correctly trained on the preceding topics. The substantial corporate of the respondents was established to have an unfortunate kind and misconceptions of the subjects tested. We have already described that the test was able to investigate and categorize students into student conception of electricity concepts. Research result with four tier tests showed scientific conception 9 %, which was likely to have misconceptions 64 %, and the students were lack of knowledge the concept of 25 %, and had an error amounted to 2 %. The elementary school students’ inclined to be unwell aware among what they diagnosed and what they do not diagnosed. It might be determined that a Four-Tier Diagnostic Test which has previously been established be able to assess elementary school students’ conception on electricity concept.

Abstract

This study aims to improve primary students’ mathematical connections and habits of mind abilities by using REACTstrategy. This research is a quasi-experimental study conducted in 003 Peranapelementary schoolin the even semester of 2017/2018. The subjects of this study were class V students. Based on the results of data analysis and findings obtained in the study, it can be concluded that there are significant differences in abilities improvement between classes that use REACT strategies and general learning with the influence of 52%. This is proved by an enhancement of students’ mathematical connections ability in the experimental class,by the average of initial testis 54.96 to 79.13 and in the final test with an average enhancement of 0.54 included in the medium category. Whereas the control class has an enhancement in the average of initial test from 55.67 to 64.33, and in the final test with the mean of 0.05.Meanwhile, students habits of mind abilities which include self-regulation, critical thinking, and creative thinking ability can appear in the experimental and control class even though these abilities do not appear in all students.
