Abstract

A survey and exploratory study were conducted to analyze Lake Tempe as a resource for contextual learning (CTL). The first phase of the study included exploring the lake’s potential through interviews with the people who live in the lake’s coastal region. Quadrat transects were done to identify aquatic plants around the lake. A feasibility analysis was conducted to see the lake’s potential as a learning resource. Field data were collected and compared to the environmental biology (EB) curriculum, responses, and learning outcome. The data were analyzed descriptively and tested using a paired-sample t-test. The results showed differences in the three stations’ physicochemical parameters and decreased quality of the water. It was found that anthropogenic activity had a significant contribution to the lake’s pollution. Nine species of six aquatic plant families were found in the lake. The survey revealed that the lake was feasible as a learning resource with criteria easy to access, safety, time efficiency, costs, and the material's suitability for EB courses. The t-test showed a difference in the students’ scores between before and after exploration practices. These findings suggest that Lake Tempe can serve as a resource for CTL in EB courses.

Abstract

This study aimed to analyze the effect of conventional, Problem-Based Learning (PBL), Numbered-Head Together (NHT), and integrated PBL-NHT learning models on the low- and high-ability students’ critical thinking. This quasi-experimental study used a pretest-post-test nonequivalent control group design with a four-by-two factorial pattern. The analysis results showed that learners’ critical thinking was impacted by learning models implemented in the classroom and influenced by the interaction between the learning models and learners’ academic abilities. There was no difference in critical thinking among low-ability students who were taught with PBL, conventional, and integrated PBL-NHT, but a difference was found in students taught using NHT. There was no difference in critical thinking between high-ability students taught with conventional and NHT instruction, but there was a difference between students taught with PBL and integrated PBL-NHT instruction. To foster critical thinking, pupils with low academic ability should be taught using NHT, whereas those with high academic ability should be taught using PBL or an integrated PBL-NHT approach.

Abstract

Mathematics teachers in integrated Islamic schools in Maluku are having problems implementing the integration of Islam into mathematics learning. This study aims to develop a learning model based on Islamic Integrated Information Communication Technology (IICT) to help teachers increase creativity in mathematical problem solving and students' environmental awareness. The main output of this research is an ICT-based active learning model that integrates Islamic sciences into mathematics learning to support the development of creativity skills in solving mathematical problems and students' environmental awareness at an early age. The development of the learning model in this study is a combination of the Plomp (2013), Dick & Carey (2015), and Joyce et al. (2009). Plomp's model was used for the research and model development phase, Dick & Carey for instructional design, and Joyce et al. for the model's contents. The resulting model is an adaptation of the hierarchical and procedural combination of the three developments. The research subjects are mathematics teachers and students. The data analysis technique used is the analysis of the instrument's validity, the IICT model, the practicality, and the effectiveness of the IICT model. Based on expert validation and testing results, the resulting model meets the needs of mathematics teachers and students of SMP/MTs in an integrated Islamic school environment. The results showed that the IICT learning model was qualified to help teachers integrate Islam in mathematics learning, increase creativity in solving math problems, and students' environmental awareness.

Abstract

The phenomenon today in schools is that teachers rarely build student arguments but only accept students' answers. However, teacher activities that always make students 'arguments and support each solution and defend students' arguments without long debates are relevant and exciting to study. This study aims to explain and explore the promotion of mathematics teacher reasoning in tasks in the classroom. The author surveyed teachers who teach mathematics at the junior high level. This research is a qualitative descriptive study with an experimental research design, which begins with a survey of teachers who teach mathematics at the junior high school level in Maluku Province. First, the authors conducted initial observations for one month in several junior high schools in Maluku Province with the guide of the observation instrument for the promotion of teacher reasoning in learning. Second, the writer states that there are three groups of attractive teachers who can promote mathematical reasoning in each of their teachings based on indicators of teachers' mathematical reasoning. Third, the writer created the same math problems for the three teachers and observed how they built students' reasoning and evaluated their thinking efficiently. Finally, the results and surveys were carried out by triangulation with direct trials on seven classes at the junior high level. The results show how teacher actions promoting mathematical reasoning give generalizations or justifications. Teacher actions supporting precise rationale are discussed in more detail in this article.

Abstract

Eco-enzyme is a liquid produced from the fermentation of non-fat organic matter as an environmentally friendly antiseptic with no harmful residues to the environment. Organic materials commonly used in the manufacture of eco-enzymes include vegetables and fruit wastes. Therefore, this study aims to produce eco-enzymes from organic wastes in the form of nutmeg, clove, and eucalyptus leaves. A laboratory experiment with a post-test-only control group design was carried out for 7 months from March to September 2021. The variable X includes the type of plant waste from which the eco-enzyme was obtained namely nutmeg flesh (BP), nutmeg leaf (DP), eucalyptus leaf (DK), clove leaf (DC), liquid antiseptic (Ae), and gel antiseptic (Ai), while variable Y was the level of E. coli and S. aureus (mm) growth inhibition. The results showed that different plant wastes' eco-enzymes also had distinctive colors, where DP and DK were brown, BP was reddish-brown, while DC appeared blackish-brown and clear. These differences occur due to variations in the chemical composition of each material used. Furthermore, the acidic aroma from each eco-enzyme was derived from the decomposition of alcohol compounds into acetic acid during aerobic respiration. The aroma was distinctively different depending on the type of plant waste used. Eco-enzymes and commercial antiseptics also have different abilities to inhibit E. coli and S. aureus growth with the highest inhibition found in eco-enzymes made from eucalyptus leaf waste. Keywords: Antiseptic, Cloves, Nutmeg, Eucalyptus
