Abstract

ABSTRACTThis study aims to generate and measure the value of the validity and practicality of the E-LKPD buffer solution. E-LKPD is prepared based on a guided inquiry model. The type of research used is Research and Development using the plomp development model. The research instrument was a content and construct validity sheet as well as a practicality questionnaire. The E-LKPD was validated by 2 chemistry lecturers at Padang State University and 1 chemistry teacher, as well as a practicality test (field test) through 15 students of class XI SMAN 4 Padang. The results of the study found that the guided inquiry-based worksheets had a high level of category validity (V=0.91) and the practicality level of students with a very practical category on the score (NP=90%). This research is recommended for further research in terms of testing the effectiveness of the products that have been developed.Keywords: Guided Inquiry, E-LKPD, Buffer Solution, Plomp ABSTRAKPenelitian ini bertujuan untuk menghasilkan serta mengukur nilai validitas dan praktikalitasE-LKPD larutan penyangga.

Abstract

design stages, this research only focuses on the development stage, namely the validity and practicality tests. The research instruments used were validation questionnaires and practicality questionnaires for teachers and students. The validity test was carried out by 5 expert teams and the practicality test was carried out on two chemistry teachers and 34 phase F students. The results of construct and content validity tests were obtained at 0.89 and 0.93 with valid categories. The results of the module's practicality test conducted by teachers and students amounted to 92.92% and 87.45% with a very practical category. The results showed that a valid and practical PBL-based reaction rate module integrated with SSI was produced for phase F students.

Abstract

This study aimed to develop Science, Technology, and Society (STS)-based student worksheets (LKPD) on the topic of substances and their changes and to examine their effectiveness in improving the motivation and learning outcomes of tenth-grade students at SMKN 1 Timpeh. This development research employed the Plomp Model, which consists of Preliminary Research, Prototyping Phase, and Assessment Phase. The participants were 32 tenth-grade students, comprising 21 students in the experimental class and 11 students in the control class. The instruments included validation sheets, practicality questionnaires, a learning motivation questionnaire, and a learning outcomes test. The data were analyzed using descriptive and inferential statistics. The results indicated that the worksheets were valid, with Aiken’s V scores of 0.86 for content, 0.90 for presentation, 0.88 for language, and 0.88 for contextual aspects, with an average of 0.88. The worksheets were also very practical, with teacher and student practicality scores of 93%. In the Assessment Phase, the experimental class showed significantly higher motivation and learning outcomes than the control class (p = 0.012). Therefore, the developed worksheets are valid, practical, and effective for chemistry learning.
