Abstract

The purpose of this study is to determine the validity of guided note taking (GNT)-based handouts on mechanical wave materials. This research is a type of Research and Development (R&D) development research using a 4D development model consisting of four stages, namely: the defining stage (define), the design stage (design), the development stage (develop), and the dissemination stage (disseminate). The instrument used is a handout validity questionnaire. Validity assessments are carried out by media, language, and material experts. The results of the validity of media experts were 0.86 with a very valid category, the validity of linguists was 0.87 with a very valid category and the validity of material experts was 0.9 with a very valid category, while the validity of all experts was 0.87 with a very valid category. From the results of research that has been done, it was found that handouts based on guided note taking are feasible to be used to increase students' interest in learning. So it can be concluded that handouts based on guided note taking (GNT) on the resulting mechanical wave material are good and valid and can be used in learning.

Abstract

This literature review aims to examine the effectiveness of Problem-Based Learning (PBL)-based Student Worksheets (LKPD) in enhancing students’ problem-solving abilities and collaboration skills. The review includes 50 articles obtained through the Publish or Perish application and indexed in SINTA 2–4, published between 2015 and 2025, covering various educational levels and fields of study. A qualitative descriptive analysis was employed to identify research patterns, characteristics of LKPD development, and the impact of PBL implementation on 21st-century skills. The findings indicate that PBL-based LKPD consistently received high ratings in terms of validity, practicality, and effectiveness. Most studies reported that PBL-based LKPD is highly feasible for use, based on evaluations by material, language, and media experts. The implementation of PBL syntax comprising problem identification, investigation, information analysis, group discussion, and solution formulation was proven effective in improving students’ critical thinking, problem-solving, and collaboration abilities. The use of authentic problems relevant to real-world contexts also promoted active, participatory, and student-centered learning, aligned with the principles of the Merdeka Curriculum. Overall, this review confirms that PBL-based LKPD is an innovative and relevant instructional tool for developing 21st-century competencies and enhancing the quality of learning in modern educational settings
