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.","PeriodicalId":32098,"journal":{"name":"Jurnal Gantang","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48106885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to create a learning device based on guided discovery to enhance students' valid, practical, and effective problem-solving skills. The developed instructional devices are presented as lesson plans and worksheets for high school math students. This development study uses the Plomp model in three phases: pre-production, prototyping, and evaluation. The research subjects are 7th-grade students of SMPN 2 Northern Rao. Experts conduct verification in mathematics education, educational technology, and the Indonesian Language. The practicality of the teaching aid is evident in the results of practicality surveys in teaching practice and questions from students and teachers. Efficiency can be seen in student learning outcomes. The Data Analysis Result Guided Discovery Learning Device is effective because it meets valid criteria in terms of content and design, is practical in terms of implementation, simplicity, and turnaround time, and can improve learning outcomes.
