The study follows the Plomp development model, covering preliminary research, prototyping, and assessment. Instruments assess validity and practicality through lesson plan and worksheet appraisal, teacher and student response questionnaires, learning implementation observations, and critical thinking tests. Results indicate validity with average scores of 3.52, very practical implementation (83.21%) and responses (80% teacher, 88.17% student), and effectiveness via 75.57% student learning completeness.","cbCaiuKyihfAy6Z0","https://ap.wps.com/l/cbCaiuKyihfAy6Z0","pdf",202964,1,7,"English","en","# Abstract\n# Introduction\n# Method","[{\"question\":\"What is the purpose of the study?\",\"answer\":\"To produce mathematics learning tools that are valid, practical, and effective for improving VII middle school students’ mathematical critical thinking ability.\"},{\"question\":\"What development model and learning content does the research use?\",\"answer\":\"The study applies the Plomp model (preliminary research, prototyping, assessment) and the learning tools contain material on flat-sided shapes.\"},{\"question\":\"How is validity, practicality, and effectiveness determined?\",\"answer\":\"Validity and practicality use assessment criteria such as average scores above 3.40 and implementation percentage at least 70%.
