Abstract

Vocabulary mastery is the initial stage in teaching elementary school studentsto understand basic Indonesian language mastery. Improving vocabularymastery in elementary school students can be done by using specific media, oneof which is the use of spelling puzzle media. This research aims to improvestudents' understanding of vocabulary through the use of spelling puzzle media.The type of research used in this research is the experimental method. Theresearch design will use one sample pretest-posttest researchdesign. The sampleused in this research was 20 grade 1 elementary school students. The results ofthe research show that there has been an increase in student learningcompleteness, where after implementing the posttest, student completeness was95%, after previously giving the pretest, the percentage of student completiononly reached 30%. This shows that the use of spelling puzzle media canincrease students' learning completeness related to elementary school levelstudents' vocabulary understanding in Indonesian language subject content.

Abstract

This study is motivated by the low learning outcomes of students. The low learning outcomes are influenced by a lack of understanding of the learning material, which is caused by students' passive involvement in the learning process, such as lack of concentration, limited active participation, and an inability to relate the learning material to everyday life. The aim of this research is to improve learning outcomes by using the Discovery Learning model. This research is a quantitative study. The research method used is an experimental method, with the experimental design being a Pre-Experimental Design, specifically the One-Group Pretest-Posttest Design. This research was conducted at SD Negeri 2 Lamcot Aceh Besar. The population of the study consisted of all third-grade students at SD Negeri 2 Lamcot Aceh Besar, and the data were collected using Purposive Sampling. The sample consisted of 21 students selected from class III-A. Based on the results of the study, there was a significant improvement in students' learning outcomes before and after the intervention. The average pretest score was 53%, and after the treatment, the average posttest score increased to 83%. The conclusion drawn from this study is that the implementation of the Discovery Learning model can improve students' learning outcomes. Therefore, the use of the Discovery Learning model can be considered as one of the effective teaching methods to be applied in Mathematics learning.

Abstract

The Low Critical Thinking Skills of Fourth Grade Students at SDIT Nurul Ishlah and the Lack of Effective Learning Media and Teaching Aids are the Background of This Research. The purpose of this research is to measure the validity, analyze the practicality, and determine the effectiveness of science teaching aids made from recycled materials in improving students' critical thinking skills. The method used is Research and Development (R&D) with the ADDIE development model, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. The results of the research indicate that the science teaching aids made from recycled materials were assessed as highly valid, with a percentage of 95.56% from media experts and 97.78% from material experts. In terms of practicality, the teaching aids were considered very practical, with a 94% rating from teachers. The effectiveness test using the One Sample T-Test produced a p-value of 0.05, indicating that these teaching aids are effective in improving students' critical thinking skills. Furthermore, the N-Gain test showed a score of 72.42%, indicating a high level of improvement in students' critical thinking skills. Overall, the science teaching aids made from recycled materials have been proven to be highly valid, practical, and effective in supporting the learning process and enhancing students' critical thinking skills.
