Abstract

Referring to the results of an international survey, one of which is PISA, the achievements of Indonesian students are still below the global average score. The main problem that is the causative factor is that students need to be used to solving similar problems. The issues used in PISA questions are familiar to only some students in Indonesia. This study aimed to develop PISA model mathematical problems with valid and reliable local contexts and potential impacts. The type of research conducted is development research using the ADDIE model with the stages of analysis, design, development, and evaluation. The test subjects were fifth-grade elementary school students in Bengkulu and South Sumatra provinces. The research instruments were product development validity sheets, legibility sheets, and student response questionnaires. Data analysis consisted of validity analysis using the Aiken Index and reliability with Cronbach Alpha. The study results show that PISA model mathematical questions with the regional context meet the validity, reliability, and potential impact criteria. The results of the implementation test showed that 11 students (27.50%) were in the low category, 32 students (55.00%), and 7 students (17.50%) were in the high category.

Abstract

The achievement of high school graduates' competence is continuously improved by the government in Indonesia, one of which is by implementing the Minimum Competence Assessment. The main problem in its application is the limitations of similar problem models provided in classroom learning so that students are not accustomed to solving them. The purpose of this research is to produce mathematical reasoning questions using the Minimum Competence Assessment model for junior high school students that are valid, reliable, and have a potential impact. This research is development research with two stages of developing Tessmer’s model, namely: (1) Preliminary and (2) formative evaluation stage, which consists of self-evaluation, prototyping (expert reviews and small group), and field tests. The trial subjects of this study were 25 students of class VIII Bengkulu state junior high school 7 in Bengkulu City. The results of the study obtained questions that met valid criteria with an Aiken index each of which was more than 0.5. The questions meet reliable criteria with a count of more than 0.6 and are in the high category. The questions have a potential impact with sufficient students' selection abilities on average and students giving a good response of more than 50.00%. The suggestion from the research is that the teacher encourages choosing a real context to present the problem in mathematics learning.Keywords: development research, instrument test, mathematical reasoning, minimum competence assessment.DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1515-1526
