Abstract

This study aims to describe the validity, practicality, and effectiveness of POE (Predict-Observe-Explain) oriented learning devices in the form of Lesson Plans (RPP), Student Worksheets (LKPD), Pre-Test & Post-Test Questions. This research uses (R&D), which consists of material analysis, literature study, design of learning devices, validation of learning devices, revision of learning devices, limited scale trials, and producing learning devices that meet the criteria of validity, practicality, and effectiveness. This study involved 15 students at SMAN 1 Gorontalo. The results show that the POE-oriented learning devices (Lesson Plan, Student Worksheet, Questions) obtained the percentage of validation results from 2 expert validators, namely 91.6% Lesson Plan, 93.3% Student Worksheet, and 91.6% Questions & from the practitioner validators obtained a percentage of 97.2% Lesson Plan, 96.6% Student Worksheet and 100% Questions with very valid criteria. The practicality of learning devices from the results of the implementation of learning is 98.16% in the very good category, the student activity is 89.2%, and the student response questionnaire reaches 87.29% in the very good category. The effectiveness of POE learning devices from the results of pre-test & post-test data analysis conducted during learning using the N-Gain test with an average score of 0,85 is in high criteria. Based on the result, it can be concluded that the development of POE-oriented learning devices on environmental change material is appropriate for classroom learning

开发预测-观察-解释型学习装置，提高学生解决环境变化材料问题的能力

本研究旨在以教案(RPP)、学生作业表(LKPD)、测试前与测试后问题的形式，描述POE(预测-观察-解释)导向学习装置的效度、实用性与有效性。本研究采用(R&D)方法，包括资料分析、文献研究、学习装置设计、学习装置验证、学习装置修订、有限规模试验、生产符合效度、实用性和有效性标准的学习装置。这项研究涉及了sman1 Gorontalo的15名学生。结果表明，面向poe的学习装置(Lesson Plan, Student Worksheet, Questions)从2位专家验证者处获得了91.6%的Lesson Plan, 93.3%的Student Worksheet和91.6%的Questions的验证结果，从实践者验证者处获得了97.2%的Lesson Plan, 96.6%的Student Worksheet和100%的Questions，并且具有非常有效的标准。从实施学习的结果来看，学习装置的实用性在非常好的类别中为98.16%，学生活跃度为89.2%，学生回答问卷在非常好的类别中达到87.29%。通过N-Gain测试在学习过程中进行的测试前和测试后数据分析结果，POE学习设备的有效性处于高水平，平均得分为0.85。基于研究结果，可以得出开发环境变化材料的面向poe学习装置适合课堂学习的结论
