The Correlation of Isomorphic, Open-Ended, and Conventional Score on the Ability to Solve Kinematics Graph Questions

Abstract

isomorphic and conventional to open-ended can reflect students' learning difficulties on kinematic's graphs. This study used a quantitative descriptive form of survey research. The respondents were twenty-nine senior high school students from Semarang. The instruments were adopted from the Test of Understanding Graphs-Kinematic (TUG-K) by Robert J.Beichner (1994). There were nine questions used from the TUG-K with open-ended questions that have been validated. The results show that students have difficulties learning about kinematic's graphs, and there is no relation between open-ended scores and the other two scores. Nonetheless, judging from the correlation coefficient, the correlation between open-ended and conventional tasks is 0.075, which means low correlation, while for isomorphic score and open-ended score in the amount of 0.109 is higher than the correlation of traditional and open-ended. This correlation is insignificant. However, the closest correlation direction to the open-ended test is isomorphic compared to the conventional one. Therefore, it is concluded that isomorphic assessment is more useful than traditional review in kinematic graphics.

Rapid Artificial Diagnostic Test in Intelligent Teacher Assistant System (ITAS) to Identify Misconceptions on Kinematics

“…One of the diagnostic tests that can identify students' misconceptions is the four-tier diagnostic test [4]. This test consists of the first level for knowledge questions in the form of multiple choice with answer choices, the second level contains the confidence of the answers at the first level, the third level contains the reasons for the answers at the first level, and the fourth level contains the level of confidence, on the reasons for the answers at the third level [5]. The four-tier test can assess misconceptions with a low error rate and cover the lack of knowledge because it can hold all the advantages of the three-tier test [6].…”
