Developing Two-Tier Diagnostic Instrument to Determine Misconceptions on Socioscientific Issues

Abstract

Socioscientific issues, which we encounter more and more frequently, will gain much more importance in the coming years. Socioscientific issues have many topics that individuals will experience decision-making processes in the future. Adequate knowledge of the concepts lies at the basis of the decision-making process. The aim of this study is to develop a two-tier diagnostic test to identify misconceptions in socioscientific issues and to study the validity and reliability of this test. In this scale, which was developed in the mixed method, there are questions about energy resources, global warming, genetic engineering and cloning. In order to develop the two-tier test, a process consisting of three basic stages was carried out: determining the content, obtaining information about students' misunderstandings, and developing the diagnostic test. The data of the study were collected from eighth and ninth grade students. In order to determine the final version of the scale; the reliability, difficulty and discrimination values were analyzed with the data of 385 students. A test-retest application was also made with the participation of 55 students. The KR-20 value of the 30-item two-tier socioscientific issues concept test developed is 0.85, the average difficulty value is 0.46987, the average discrimination value is 0.497364, and the Pearson Correlation coefficient for test-retest reliability was 0.776. As a result of the study, a valid and reliable two-tier diagnostic test consisting of 30 items that can be used to identify misconceptions in socioscientific issues has been developed
