Abstract

Digital inequality and the pandemic have exacerbated the learning crisis, caused some learning loss, also fostered students’ individualistic attitude, which resulted in poor collaboration skills. Furthermore, the models and approaches in the teaching material activities have not reflected the stages that encouraged the practice to enhance collaboration skills. Meanwhile, collaboration skills can be trained and developed by selecting the right teaching materials that are integrated with appropriate learning models. The development of PjBL-STEAM-based E-Module is believed to be able to improve students' collaboration skills. This study used a quasi-experimental design with basic random sampling. There were two study groups: the experimental and the control groups. The instruments used in this study were a self-assessment questionnaire measuring students’ collaboration skills and teachers’ observation sheets that aligned with the collaboration skill indicators. ANCOVA test was used to analyze the data. The findings showed that the E-Module has no significant effect on students' collaboration skills (α=0,213), while the covariates indicated some factors that significantly affect the improvement of students’ collaboration skills (α=0,004). The validation results of the PjBL-STEAM-based E-Module suggested that it is highly valuable to implement in the teaching and learning process.

Abstract

E-module is considered as an effective learning media to create an interactive learning environment. In spite of that it is rare to find the research that examines the development of e-module based on Problem-Based Learning model that integrates Socio-Scientific Issues on argumentation skills to students. This research aims to develop students’ argumentation skills through problem-based e-module with socio-scientific issues topics. The researcher used pre-experimental method with one-group-pretest-posttest design. The e-module was implemented to 36 students of Biology Education, State University of Malang, for the 2nd-year from November to December 2022. The research sample was selected by non-random sampling. The research samples were selected by non-random sampling. The research data were collected by opened-ended questions to assess the students’ argumentation skills and categorized based on the argumentation skills rubric. The data were analyzed based on the increase of pre-test and post-test scores by using Normalized Gain (N-Gain). The result of the N-Gain calculation showed a score of 0.46 which means the students’ argumentation skills developed in the moderate category after the implementation of using problem-based e-module with socio-scientific issues topics. The problem-based e-module with socio-scientific issues topics can train students to identify the problems, analyze data and evidence to give problem-solving solutions packaged of complex argumentation.

Abstract

It is important to carry out exploration of pteridophyte biodiversity in Ijen Crater Nature Preserve because with extreme natural conditions, we expected to get potential species for medicine purpose. In addition, knowing the diversity and abundance of a species becomes a conservation consideration. We found only one species of the genus Dicranopteris, i.e. Dicranopteris linearis (Burm. F) Underw. with low abundance (4-10 individuals per cluster) and only found in one location. This shows that this species needs attention due to its rarity in the area and further phytochemical analysis is needed to determine its potential as a drug.

Abstract

Serangga tanah merupakan salah satu bagian dari ekosistem hutan. Kehadiran serangga tanah dalam ekosistem hutan berperan dalam proses dekomposisi. Semakin tinggi keanekaragaman serangga tanah, maka semakin besar pula peranannya bagi ekosistem hutan. Kehadiran serangga tanah dapat berkurang dikarenakan oleh beberapa gangguan salah satunya kebakaran hutan. Kebakaran hutan menyebabkan dampak seperti berkurangnya keanekaragaman hayati. Tujuan dalam penelitian ini adalah untuk membandingkan keanekaragaman serangga tanah (epifauna) berdasarkan perbedaan lahan yaitu lahan bekas kebakaran, lahan transisi, dan lahan tidak terbakar pada salah satu kawasan Taman Nasional Baluran. Penentuan lokasi plot sampling dilakukan dengan metode line transek berdasarkan kemiringan lahan pada lokasi tersebut. Setiap lahan masing-masing terdapat enam line transek. Setiap 10 meter dalam garis transek dipasang Pitfall trap sehingga terpasang 120 plot. Serangga tanah yang terjebak kemudian akan diidentifikasi menggunakan bantuan mikroskop komputer dan dicocokkan dengan buku identifikasi serangga. Serangga tanah yang telah teridentifikasi dihitung jumlah individu per-plot dan dianalisis dengan menghitung indeks keanekaragaman (H’), indeks kemerataan (E), indeks kekayaan (R), dan indeks nilai penting (INP) yang selanjutnya dilakukan analisis ANAVA menggunakan bantuan program pengolah data. Hasil analisis menunjukkan bahwa nilai H’, E, dan R serangga tanah pada setiap lahan berbeda tetapi tidak berbeda pada tiap kemiringan. Nilai INP tertinggi pada ketiga lahan di miliki oleh Oecophylla smaragdina.

Abstract

Metacognitive skills are important because they help people develop an understanding of effective strategies. This skill also helps improve one's critical thinking and creative thinking so as to be able to overcome problems in everyday life. The purpose of this research is to train students' metacognitive skills through biology learning using the EAQD-PC learning model (acronym of exploring, analyzing, questioning, defining-peer coaching) which is integrated learning journals (LJ). This research was conducted at the University of Muhammadiyah Bone, South Sulawesi, Indonesia. Using a quantitative research design, 43 students were taught by EAQD-PC-LJ. Metacognitive skills were tested with an essay test three times. Previous essay tests were validated by expert raters and tested on previous batches of students to measure empirical validity and reliability. All tests are valid and reliable. The results of the treatment showed an improvement in students' metacognitive skills through three tests. The findings of this study prove that EAQD-PC-LJ is effectively used to improve students' metacognitive skills through the learning process. Learning journals have an important role as a tool to train students' mastery of concepts and knowledge.
