Abstract

ABSTRAK Penelitian ini bertujuan untuk mengembangkan instrumen tes keterampilan pemecahan masalah peserta didik yang valid dan reliabel pada konsep usaha dan energi. Penelitian ini dilakukan dengan model pengembangan 4D yang terdiri dari tahap define, design, develop, dan disseminate. Hasil uji validasi oleh ahli dan praktisi ditinjau dari aspek materi, aspek konstruksi, dan aspek bahasa. Berdasarkan hasil uji validasi ahli diperoleh presentase skor 94.23% untuk aspek materi, 89.00% untuk aspek konstruksi, 80.00% untuk aspek bahasa dan berdasarkan uji validasi praktisi di peroleh presentase skor 97.95% untuk aspek materi, 96.00% untuk aspek konstruksi, 92.50% untuk aspek bahasa serta dinyatakan valid pada uji validasi empiris dengan reliabilitas 0,839805 kategori tinggi pada uji terbatas. Berdasarkan hasil penelitian tersebut, dapat disimpulkan instrumen tes yang dikembangkan telah valid dan reliabel.

This research was conducted with a 4D development model which consisted of define, design, develop, and disseminate. Validation tests by experts and practitioners were in terms of material aspects, construction aspects, and language aspects. Based on the results of expert validation tests, the percentage score of 94.23% was obtained for material aspects, 89.00% for construction aspects, 80.00% for language aspects and based on practitioners' validation test the scores were 97.95% for material aspects, 96.00% for construction aspects, 92.50% for aspects language and stated as valid in the empirical validation test with a reliability of 0.839805 in high category on the limited test. So it could be concluded that the test instrument was valid and reliable. Keywords: Test instruments, Problem Solving Skills, Work and Energy

高中阶段对企业和能源概念的问题解决技能测试

本研究旨在开发有效的学习者问题解决技能测试工具，以确定企业和能源概念。该研究采用了由定义阶段、设计、设计和分歧组成的4D开发模型。专家和实践者对物质、建筑和语言方面的测试结果进行了权衡。根据专家的验证试验结果的百分比分数94。23%的物质方面,89 . 00%建筑方面,80 . 00%为语言和基于从业者在验证测试得到的百分比方面得分97。95%的物质方面,96。00%建筑方面,50% 92。为了有效的语言和表达方面的实证验证试验最终用更高的有限测试0.839805类别的可靠性。根据这项研究，可以推断开发的测试仪器是有效的和可靠的。关键字:测试仪器、问题解决技能、努力(工作)和能源假设，这项研究的工具对学生有效并值得信赖，因为问题解决了工作和能源的概念。这项研究涉及的是一种基于定义、设计、设计和分歧的4D开发模型。专家和实践的验证是基于aspects、构造助推和语言助推的。改编自the results of专家validation测试,94之percentage得分。23%获得属于aspects, 89 . 00%为建筑材料aspects, 80 . 00% for language aspects和改编自practitioners“validation测试得分了95%是97。for aspects, 96 . 00%为建筑材料为aspects language和stated aspects, 92。50%的有效美国《empirical validation test with a的可靠性高类别里的0。839805 on the limited)测试。所以可以确定这些仪器是有效和可靠的。关键字:仪器测试，焊接技能问题，工作和能量
