Abstract

This article examines how in an educational setting communication skills can enhance critical thinking abilities through guided inquiry. Human resources (HR) must be improved in light of the Industrial Revolution 4.0, but obstacles to learning include low student engagement, a lack of enthusiasm, and a lack of critical thinking abilities. Although communication skills are frequently a barrier, guided inquiry is recognized as a learning model capable of advancing students' critical thinking abilities. The activity steps in guided inquiry are covered in this article, along with pertinent communication skills such as explanation of delivery, material mastery, group interaction, and responding. It is highlighted how critical thinking abilities and communication skills are linked in 21st-century learning. It is widely acknowledged that effective verbal, written, and listening communication skills are essential for guided inquiry. Source triangulation was employed as a qualitative research method with a post-positivism approach to gather data. The article emphasizes how communication skills help students develop their critical thinking abilities by enabling them to assess and connect information to a wider context in addition to gathering and analyzing it. The conclusion highlights the need of communication abilities

Abstract

This research aims to determine the effect of e-book teaching materials on Temperature and Heat Science materials packaged with the STEM-PjBL approach in increasing students' learning motivation and creative thinking abilities. This research uses a quasi-experimental quantitative research method with a one group pretest-posttest design. The subjects in this research were 32 students in class VII C of SMP Negeri 5 Depok. The results of the research that has been carried out show the high learning motivation of students. For each indicator the conformity point is above 50%, so in this case it can be stated that students' opinions are more interested in using STEM-PjBL based science e-books. Meanwhile, students' creative thinking abilities show N-Gain values ​​in each aspect, namely fluency of 0.45, flexibility of 0.38, novelty of 0.61, and usefulness of 0.62. The average N-Gain for creative thinking ability is 0.52 in the "Medium" category. In this way, STEM-PjBL based science e-books can create learning motivation and creative thinking abilities in students

Abstract

The process of learning interactions between living things and the environment requires direct observation by students, but in reality the school is located in the city center with a less than optimal surrounding environment. The availability of learning media for this material has not been widely developed by students. The research aims to produce aquascape media that is suitable as an aid in learning interactions between living things and the environment to improve students' mastery of concepts and communication skills. The research uses a 4D development model which includes Define, Design, Develop, and Dessiminate. The test subjects were taken using a cluster random sampling technique and a sample of 66 students at SMPN 12 Yogyakarta was obtained, consisting of experimental and control classes. The field test used quasi-experimental research with a nonequivalent control group design. The feasibility, teacher practicality, and effectiveness of assessing aquascape media as an aid in learning interactions between living creatures and the developed environment are included in very good and practical.

Abstract

This study aims to evaluate the effectiveness of three types of zeolite, namely fresh zeolite, saturated zeolite, and zeolite activated using 0.5 M sulfuric acid in adsorbing iron metal ions (Fe³⁺) from simulated wastewater solutions. This study also aims to understand the effect of variations in contact time (1 to 5 days) on the adsorption efficiency of Fe³⁺ ions, as well as to prove whether the activation process is able to regenerate the adsorption capacity of saturated zeolites. The method used is a laboratory-scale batch method, where each type of zeolite is immersed in a 10 ppm FeCl₃ solution for 1 to 5 days. Each treatment was carried out on 15 samples, and the Fe³⁺ ion content after the adsorption process was measured using an Atomic Absorption Spectrophotometer (AAS). Zeolite activation was carried out by immersing saturated zeolite in 0.5 M H₂SO₄ for 24 hours, followed by washing to neutral pH and drying at 200°C.  The results showed that the average efficiency of activated zeolite reached 99.15%, which is only 0.4% smaller than the average adsorption efficiency of fresh zeolite which is 99.55%. Saturated zeolite without activation showed a significant decrease in performance with an average efficiency of only 61.852%. Based on the results of the ANOVA test showing a p-value of 0.001 which is smaller than the p-value of 0.005 in the table, there is a difference in adsorption between activated zeolite and fresh zeolite with saturated zeolite. This indicates that acid activation of zeolite can effectively regenerate the adsorption capacity and extend the service life of zeolite in chemical waste treatment.

Abstract

Chemistry education is often considered difficult because many concepts are abstract. Therefore, local wisdom-based learning media are needed to make learning more contextual and relevant to students’ experiences. This study aimed to map research trends on the integration of local wisdom into chemistry learning media using a Systematic Literature Review. Articles were collected from Scopus and Google Scholar (2015-2025), limited to empirical studies. Of the 515 initially identified articles, 24 met the inclusion criteria and were analyzed. The findings show that studies were dominated by the development of modules and e-modules (25%), mainly for high school students (88%), with acid-base chemistry being the most frequently studied topic (29.17%). Research variables focused on media feasibility (70.83%), while affective aspects, chemistry literacy, immersive digital media, and broader regional representation of local wisdom remain limited. This study provides research trend mapping and directions for developing more innovative and contextual chemistry learning media.

Abstract

The achievement of environmental literacy of students in Indonesia still faces various problems. Even though environmental literacy is one of the important literacy for students to have. This study aims to determine the profile of environmental literacy among junior high school students and the need for integrated science teaching materials based on problem based learning (PBL) at Rawa Bento. The population of this study consists of junior high school students from six schools in Kerinci Regency. The research sample includes 90 students selected using a purposive random sampling technique. Data collection is conducted through instruments such as tests to measure environmental literacy and student response questionnaires to determine the need for integrated science teaching materials based on PBL at Rawa Bento. The data in the study are analyzed using quantitative descriptive analysis techniques. The research findings are as follows: 1) the majority of students have low to moderate levels of environmental literacy. 38.9% of students still have a low level of environmental literacy, 54.4% fall into the moderate category, and only 6.7% are in the high category; 2) the lowest ability of students is in analyzing the impacts resulting from environmental issues; 3) there is a need for the development of integrated electronic teaching materials based on PBL at Rawa Bento to enhance students' environmental literacy. Based on the results of the study, it can be concluded that the environmental literacy of students from six schools in Kerinci Regency is in the medium category
