This study analyzes the effectiveness of digital educational games, particularly the “Who Am I?” game on the Wordwall platform, in enhancing students’ knowledge of Indonesian language learning. The research is motivated by the need for junior high school teachers to design engaging learning methods that can foster enthusiasm among adolescents. Educational games are viewed as innovative media that present concepts in a simple yet enjoyable way, making lessons more interactive and accessible. Using a descriptive quantitative approach, the study involved 30 eighth-grade students at SMP Negeri 38 Surabaya. Data collection included pre-tests and post-tests to quantitatively measure learning outcomes, as well as questionnaires to capture student responses. Findings indicate a notable improvement in student achievement after the application of the “Who Am I?” game. The average pre-test score was 71.33, which rose to 91.00 on the post-test, showing an increase of 19.67 points. Results of a paired t-test confirmed that the difference was statistically significant, demonstrating that the improvement was due to the intervention. Additionally, questionnaire results showed that students felt more motivated, engaged, and able to understand the material more effectively through this game. Overall, the “Who Am I?” game on Wordwall proved to be an effective learning tool, and its use is recommended for teachers seeking to implement game-based strategies in classroom instruction.

This research is motivated by the fact that effective sentences in historical articles can be a path to progressive learning. The article “Sejarah Dunia” (World History), October 2024 edition on sejarahkita.com, was chosen as the object of research because of its relevance as a medium that can provide historical information in a clear and interesting way. Therefore, this study aims to analyze the effectiveness of sentences in articles that are directed at history education, which not only focus on facts but also on the development of critical thinking skills. The method used is descriptive qualitative with listening and recording techniques. The author analyzes the sentence structure, word choice, coherence between sentences, and the chronological flow of the article using distributional and matching methods. The collected data will be tabulated to identify syntactic errors, accuracy of diction, and spelling. The findings show that the article contains a number of shortcomings in sentence structure, where the message conveyed is less clear. However, in some ways, the article also succeeds in conveying an informative and relevant history. This study will provide benefits and insights into effective sentences in historical articles to provide a basis for readers to understand various suggestions and models for progressive learning oriented towards critical thinking. In addition, this study also provides added value by preserving historical values through an easy and interesting presentation.

Opinion is a person's opinion or thought regarding a problem that is currently occurring in society. An opinion must pay attention to the effectiveness of the sentence so that the reader can capture its contents. Therefore, this study will focus on the effectiveness of a sentence in a collection of opinions. This study was conducted to describe the effectiveness of sentences in a collection of opinions as critical reading teaching materials. This type of study is qualitative with a descriptive method; the technique for collecting data is using the listening and note-taking technique. The results of this study indicate that there are still several sentences that are not effective, so that readers have difficulty capturing their contents properly. Effective sentences meet requirements such as the economy of words, commensurate structure, logical language, and careful reasoning. Meanwhile, ineffective sentences occur because the structure of the sentence does not show unity, is wasteful of words or long-winded explanations, and lacks clarity in conveying information. The benefits of this study, in practice, are that it makes it easier for readers to determine the effectiveness of sentences in a collection of opinions. This study took data in the form of ineffective sentences contained in a collection of opinions for statistical literacy, the November 2024 edition of critical reading teaching materials for high school students.

This study aims to analyze the skills of understanding Arabic letters and reports at Madrasah Nurul Istifadah and identify factors that influence students' understanding, the learning methods used, and the effectiveness of the strategies applied. Understanding skills in this context include the ability to recognize text structure, analyze content, and interpret formal language styles. The study used a qualitative descriptive approach with data collection methods in the form of observation, interviews, and documentation. The results of the study showed that group discussion strategies and repeated reading with gradual understanding proved effective in improving students' understanding of Arabic letters and reports. This strategy not only improves students' linguistic abilities, but also encourages cooperation, self-confidence, and critical thinking skills. This study is expected to contribute to the development of more contextual and effective Arabic language learning methods, especially in understanding formal texts.

This study aims to describe and analyze various forms of lexical errors found in the observation report texts in Indonesian language textbooks for eighth-grade junior high school students, as well as identify inappropriate diction based on categories such as connotative, denotative, formal, informal, general, specific, and borrowed foreign words. The research utilized a qualitative descriptive linguistic analysis of three authentic and representative observation report texts. The findings indicate numerous lexical errors, including the use of foreign terms without equivalents, redundant synonyms, and words inappropriate for formal or scientific contexts. These errors potentially reduce communication effectiveness, disrupt message clarity, and affect language correctness within the texts. If left uncorrected, such errors may cause ambiguities and hinder students’ comprehension of the reports objectively and accurately. Suggested corrections include selecting precise, specific words aligned with Indonesian language norms and employing neutral, objective language to facilitate student understanding and strengthen the educational value of the textbook. These findings provide valuable references for developing quality teaching materials and enhancing teachers’ and authors’ competencies in crafting effective, standards-compliant texts. This research is expected to offer practical and theoretical benefits, ultimately improving the overall language learning process in educational settings.

Mathematical Problem-Solving Ability (KPMM) is one of the essential skills that must be developed, as it trains students to formulate appropriate solution strategies, understand the meaning of each step, and cultivate systematic thinking habits. One of the tools that can be utilized to support the development of KPMM is the use of Student Worksheets (LKPD). Various studies have demonstrated the effectiveness of using LKPD in improving students' KPMM; however, comprehensive reviews that specifically examine the effectiveness of LKPD based on educational level and the form of LKPD used are still limited. Therefore, this study aims to analyze and synthesize previous research findings on the effectiveness of LKPD in supporting students’ KPMM in terms of educational level and LKPD format through a meta-analysis method. The population and sample of this study consist of journal articles and national conference proceedings selected according to PRISMA guidelines. The results of the meta-analysis show that the use of LKPD has a very strong influence on enhancing students' KPMM, with an effect size of 2.123. Based on educational level, LKPD is proven to be more effective when used at the junior high school level (SMP) compared to the senior high school level (SMA), while in terms of format, digital LKPD is more effective than printed LKPD in supporting students' KPMM.
