2024-09-14T01:56:00+00:00

Chemistry practicum learning requires a comprehensive approach, which improves understanding of concepts and develops various essential skills needed in the professional and academic world. This research aims to develop a Guided Inquiry-Scientific Laboratory-based Health Chemistry module and conduct empirical feasibility tests. This module is designed with a guided inquiry approach integrated with scientific methods in laboratory activities. The practicum module was developed for second-grade vocational school students in health expertise with material covering colloids, hydrocarbons, polymers, biomolecules, and chemical separation. This development research uses the Borg and Gall model, which consists of planning, organizing, implementing, assessing, and analyzing data. This research was only carried out to the validation stage by material experts, media experts, peer reviewers, and reviewers (five Health Vocational School teachers). The assessment carried out by the reviewer includes eight assessment aspects with 30 assessment indicators. Data was collected through questionnaires, observations, and interviews. Data analysis was carried out descriptively, quantitatively, and qualitatively, guided by ideal assessment criteria to determine the quality of the practicum module. The research results show that the Guided Inquiry-Scientific Laboratory (GISL) based Health Chemistry practicum module that has been developed has a score of 132.52 with an ideal percentage of 88.3467% in the very good (SB) category. This indicates that this module is suitable for use in health chemistry practicum learning, and it is hoped that this research can be continued at the next stage.

Systematic Literature Review: Mathematical Literacy Skills in Terms of Mathematics Learning Motivation

2024-06-30T11:31:18+00:00

Mathematical literacy and motivation to learn mathematics are two important aspects of education. Mathematical literacy enables students to understand and apply mathematical concepts in everyday life, as well as think logically and solve problems. Mathematics learning motivation influences students' effort and perseverance in learning the material, improving academic interest and performance. The combination of the two is essential for educational success and the development of critical thinking skills required in the modern world. The objectives of research generally cover the following aspects Measuring Mathematics Literacy Level, Assessing Mathematics Learning Motivation, Identifying the Relationship between Mathematics Literacy and Learning Motivation, Recognizing Barriers and Challenges, Developing Effective Learning Strategies. This research uses the SLR (Systematic Literature Review) method by reviewing 16 articles. Data collection in this study was carried out by reviewing all articles related to Mathematical Literacy Ability, Learning Motivation, Mathematical Literacy Ability in terms of Learning Motivation published from 2019 to 2023. Based on the results of the study, it was found that motivation to learn mathematics plays an important role in students' mathematical literacy skills. Students with low motivation tend to learn by force, so their mathematical literacy skills are low because they tend to do problems procedurally without in-depth analysis. The implication is the need for motivational strategies, curriculum design, teacher training, literacy programs, and parental involvement.
