摘要

一些研究表明,学生对科学过程技能的掌握程度仍然很低,这是由于使用了不适当的学习方法,使学生不能最佳地理解应用科学过程的技能。因此,教育工作者需要使用一种能够训练学生掌握科学过程技能的方法。一种应用科学工作原理的方法是STEM方法。STEM方法在学习中的整合可以支持对科学过程技能的掌握。本研究旨在开发基于stem的生态材料模块,以提高学生的科学处理技能。本研究的开发研究(R&D)方法采用四维模型。模块效度测试用于评估开发的模块,使用来自媒体和材料专家的验证问卷形式的工具进行测量。数据分析技术使用定量方法,即计算李克特量表的百分比值。经过两位专家验证者的测试,该模块的序列效度分别为97%和98%。教师和学生的实用性测试结果分别为81%和93.71%,表明该模块具有很强的实用性。模块有效性测试分析,N-gain得分为0.76,标准较高,即科学处理技能提高。因此,开发的基于stem的生态系统模块是有效的、实用的和有效的,并且易于理解生态系统材料,增加了解决环境问题的敏感性,成为提高学生科学过程技能的一种努力。

STEM Based Ecosystem Module: An Effort to Improve Students’ Science Process Skill
Students' mastery of science process skills is still low, as illustrated in several studies caused by the use of inappropriate learning methods so that students do not understand the skills of applying science processes optimally. Therefore, educators need to use an approach that is able to train the mastery of science process skills. One approach that applies scientific work principles is the STEM approach. The integration of the STEM approach in learning can support mastery of science process skills. This study aims to develop the STEM-based modules on ecosystem material in order to improve students' science process skills. The development research (R&D) method in this study uses 4D models. A module validity test is used to evaluate the developed module, which is measured using an instrument in the form of a validation questionnaire from media and material experts. Data analysis techniques use quantitative methods, namely calculating the percentage value of the Likert scale. The module is very valid, according to the testing of two expert validators, with sequential validity percentages of 97% and 98%. The results of the practicability test for educator and student responses are 81% and 93.71%, respectively, indicating that the module is very practical. The analysis of the effectiveness test of the module obtained an N-gain score of 0.76 with high criteria or it was said that science process skills increased. Thus, the developed STEM-based ecosystem module is valid, practical and effective, and makes it easy to understand ecosystem material, increases sensitivity to solving environmental problems and becomes an effort to improve students' science process skills.
