摘要

酸碱材料在酸碱强度的概念和pH值的计算上存在困难。测试结果显示,68名学生中有87%的人低于KKM。使用基于本地智慧的LKPD学习可以使学生更容易理解材料并提高学习效果。STEAM方法可以训练学生将他们的知识应用到设计中,作为利用技术解决环境问题的一种形式。本研究的目的是确定LKPD的有效性。使用的研究类型是实地研究,使用的设计是前测后测对照组设计。数据收集技术,即访谈,文件,问卷调查和测试问题,然后使用N-Gain测试进行分析。研究结果表明,采用STEAM方法的基于局部智慧的LKPD在学习成果方面的有效性显示出N-Gain值为0.3,其标准为“中等”,即学生体验到理解的增加。从平均方面看,学生情感评价为“很好”,学生精神运动评价为“好”。小规模实验结果表明,开发的LKPD适用于酸碱类化学学习,能有效提高学生的理解能力。

Efektivitas Lembar Kerja Peserta Didik (LKPD) Berbasis Kearifan Lokal dengan Pendekatan STEAM pada Materi Asam Basa
Acid base material has difficulties in the concept of acid base strength and pH calculations. The test scores for acid-base material showed that 87% of the 68 students were below the KKM. Learning using LKPD based on local wisdom can make it easier for students to understand the material and improve learning outcomes. The STEAM approach can train students to apply their knowledge in making designs as a form of solving environmental problems by utilizing technology. The purpose of this study is to determine the effectiveness of LKPD. The type of research used is field research with the design used is the pretest posttest control group design. The sources in this study came from ten students of class XI IPA MAN Insan Cendekia Paser who were selected by simple random sampling. Data collection techniques, namely interviews, documentation, questionnaires and test questions, were then analyzed using the N-Gain test. The results of the study show the effectiveness of local wisdom-based LKPD with the STEAM approach in terms of learning outcomes showing an N-Gain value of 0.3 with the criteria of "moderate" meaning that students experience an increase in understanding. Judging from the average aspect of the affective assessment of students "very good" and psychomotor assessment of students "good". The results of research on a small scale prove that the developed LKPD is suitable for use in chemistry learning on acid-base material and can be effective in increasing students' understanding.

期刊介绍: Orbital: The Electronic Journal of Chemistry is a quarterly scientific journal published by the Institute of Chemistry of the Universidade Federal de Mato Grosso do Sul, Brazil. Original contributions (in English) are welcome, which focus on all areas of Chemistry and their interfaces with Pharmacy, Biology, and Physics. Neither authors nor readers have to pay fees. The journal has an editorial team of scientists drawn from regions throughout Brazil and world, ensuring high standards for the texts published. The following categories are available for contributions: 1. Full papers 2. Reviews 3. Papers on Education 4. History of Chemistry 5. Short communications 6. Technical notes 7. Letters to the Editor The Orbital journal also publishes a number of special issues in addition to the regular ones. The central objectives of Orbital are threefold: (i) to provide the general scientific community (at regional, Brazilian, and worldwide levels) with a formal channel for the communication and dissemination of the Chemistry-related literature output by publishing original papers based on solid research and by reporting contributions which further knowledge in the field; (ii) to provide the community with open, free access to the full content of the journal, and (iii) to constitute a valuable channel for the dissemination of Chemistry-related investigations.
