Development of Mathematical Student Worksheets Based on Scientific Approaches and PQ4R Learning Strategies on Associated Materials

Abstract

Purpose of the study: The purpose of this study was to produce math worksheets based on a scientific approach and PQ4R learning strategies on set material in class VII SMP and to find out whether worksheets based on scientific approaches and PQ4R learning strategies on set material for class VII SMP meet the valid, practical and effective criteria.
 Methodology: This type of research is development research with the ADDIE development model. This study designed worksheets, gave tests to find out student learning outcomes, and gave questionnaires to find out the results of student responses. The instruments used in this study were material and design expert assessment sheets of worksheets, teacher and student response questionnaires and observation sheets, learning achievement tests, and student response questionnaires in use trials.
 Main Findings: The process of developing student worksheets that have been carried out is followed by the validation stage carried out by material experts, obtaining a score of 95 in the "Good" category and design experts obtaining a score of 43 in the "Very Good" category. The individual trial phase scored 68 in the "Very Good" category.
 Novelty/Originality of this study: From the analysis results, student responses reached 90.63% with very positive responses, and the learning outcomes test obtained 86.49% of student scores reaching the minimum completeness criteria. This means the worksheet is valid, practical, and effective for learning mathematics in junior high schools, especially in learning sets.

The Relevance Of Ki Hajar Dewantara's Educational Basis "Education That Independent Students" In Differentiation Learning In The Independent Curriculum

“…Ki Hajar Dewantara emphasized the importance of respecting each student as a unique individual and having different potential. In the Merdeka Curriculum, the differentiated learning approach allows teachers to treat each student inclusively and recognize their diversity and uniqueness [28]. Teachers identify each student's needs, interests, and ability levels, and then adapt learning strategies to meet those needs.…”

“…The differentiated learning approach allows space for each student to participate actively in setting learning goals, exploring their interests, and developing skills relevant to their needs. By allowing students to have control over their own learning process, this concept provides an opportunity for them to feel more involved and responsible for their academic and personal development [28]. The differentiated learning approach also allows for increased collaboration between teachers, students and other stakeholders in the learning process.…”

The The Development of Electronic Students’ Worksheets (E-LKPD) Based on Argument Driven Inquiry Learning Model to Improve Scientific Argumentation Skills

“…Technology allows teachers and education providers to always innovate teaching materials so that learning takes place more effectively [15].Teaching materials that were originally printed can be designed using digital media to become electronic teaching materials. Electronic student worksheets can contain more effective pictures, animations and videos, so that students do not feel bored [16].This research utilizes the Canva application in the media development process.…”

Applying the Rasch Model to Assess Retention and Transfer Test Instruments in Science Education on Additive and Addictive Substances

“…In an effort to improve the quality of measuring student performance in science material on additives and addictive substances, an evaluation instrument is needed that can provide valid and reliable results. Evaluation is an assessment action that aims to measure the level of success of a learning process [7], [8]. In measurement, there is a comparison between a prediction and a certain standard.…”
