Educators continue to encounter challenges in designing effective instructional tools, particularly in selecting learning models that actively engage students. This study aims to develop Predict-Observe-Explain (POE)-oriented learning tools for ecology and biodiversity topics that meet validity standards. The research employs the ADDIE development model—comprising Analysis, Design, Development, Implementation, and Evaluation phases. Validity assessments conducted by two expert validators resulted in scores of 93.75% for the Lesson Plan (RPP) and 87.5% for the Student Worksheet (LKPD), both classified as "very valid." These results indicate that the developed POE-based learning tools are highly suitable for use in science instruction at SMP Negeri 7 Gorontalo. By incorporating the POE model, the tools are designed to enhance students’ conceptual understanding and foster active, inquiry-based learning.

This study aims to characterize several Rubiaceae species found at the university, located in Banjarmasin. Based on research by Stebbins & Khush (1961), the findings revealed that the only type of stomata observed across eight Rubiaceae species was of the parasitic variety. The species studied include Ashoka (Ixora paludosa L.) sp. 1, sp. 2, sp. 3, and sp. 4; Noni (Morinda citrifolia L.); Nusa Indah (Mussaebda frobodosa); Plate Glass (Gardenia augusta); and Coffee (Coffea sp.).

Science literacy is a vital competency that equips students to address the challenges of the 21st century. To foster science literacy, effective teaching materials that support active learning are essential. This study aimed to assess the design and feasibility of a Problem-Based Learning (PBL) integrated Biology Learning Activity Sheet (LKPD) with the Unity of Sciences framework to enhance science literacy skills among Grade XI science students. The research applied a Research and Development (R&D) approach using the 4D model, consisting of the stages: Define, Design, Develop, and Disseminate. The LKPD was developed based on PBL principles and integrated with the Unity of Sciences framework, utilizing the Canva application for design. Validation results showed that media validators rated the LKPD at 77% (feasible), material validators at 92% (very feasible), learning methodology validators at 96% (very feasible), Unity of Sciences integration validators at 92% (very feasible), and the science literacy validators found that 30 literacy questions were valid. Additionally, biology teachers rated the LKPD at 88% (very feasible), and student responses also indicated a rating of 88% (very feasible). Based on these findings, the PBL-based Biology LKPD integrated with Unity of Sciences to promote science literacy skills is deemed highly feasible by expert validators, biology teachers at SMA Al-Muhadjirin, and students.

This study aims to analyze teachers’ needs in developing project-based learning (PjBL) modules to address students’ learning requirements on the topic of viruses. The research was conducted at SMA Negeri 1 Indralaya Selatan, SMA Negeri 1 Indralaya, SMA Negeri 1 Indralaya Utara, and SMA Negeri 1 Tanjung Raja. Data were collected through documentation and interviews, and analyzed using a descriptive qualitative approach. The findings reveal that the application of PjBL in teaching virus-related material remains suboptimal. Teachers face several challenges, including: (1) difficulties in understanding and designing teaching modules; (2) uncertainty in selecting appropriate learning models; and (3) continued reliance on manually created, non-digital modules. From the students’ perspective, challenges include: (1) being required to study independently with minimal support; (2) limited engagement in practical or hands-on activities; and (3) low motivation due to the predominance of lecture-based instruction. In light of these findings, the study suggests the development of electronic project-based teaching modules using the Kodular application as a solution to enhance students’ critical thinking skills and provide more meaningful and engaging learning experiences.

Teacher interviews revealed a lack of student enthusiasm during lessons, particularly on the topic of the human circulatory system. The media commonly used—student worksheets (LKPD) and textbooks—were considered somewhat helpful but insufficiently engaging due to their monotonous nature. Teachers also expressed the need for electronic learning media to diversify instructional methods. In response, this study developed an educational game using the Baamboozle webtool, selected for its ease of use and interactivity. The objectives of this study were to evaluate the validity of the educational game and assess student responses to its use. A Research and Development (R&D) approach was employed, following the Research-Development-Research (R-D-R) model. Data were collected through expert validation and student response questionnaires. Validation results showed high levels of validity across media design (98.18%), content (93.33%), and language (88%), all categorized as “very valid.” Student responses were also highly positive, with an average score of 92.47%. These findings indicate that the Baamboozle webtool-based educational game on the human circulatory system is highly valid and well-received by students, suggesting its effectiveness as a digital learning medium.

Growing awareness of environmental sustainability has emerged as a significant challenge in the modern era, particularly for the younger generation as agents of change. Education plays a vital role in fostering environmental literacy to develop individuals who are both knowledgeable and environmentally conscious. This study aims to analyze students’ ecological knowledge and environmental care attitudes in biology learning at SMA Muhammadiyah 2 Bandar Lampung. The research employed a descriptive quantitative method, with a sample of 65 students selected through purposive sampling from a population of 212. Data were collected using questionnaires and tests developed based on indicators of ecological knowledge and environmental care. The results indicate that students’ ecological knowledge falls into the “good” category, with a score of 66.15%, reflecting a satisfactory understanding of ecosystems, biodiversity, and environmental threats. Similarly, students’ environmental care attitudes also fall into the “good” category, with a score of 67.33%, demonstrating awareness and commitment to environmental preservation.

Pteridophyta is one of the plants that has many benefits, both in terms of ecology, economy, and pharmacology. However, Pteridophyta still gets less attention when compared to other types of plants. Therefore, it is necessary to carry out an inventory study of the Pteridophyta species on the banks of Kembang River, Aranio Village, Banjar Regency. This study aims to describe the types of ferns (Pteridophyta) on the banks of Kembang River, Aranio Village, Banjar Regency. The sampling method used is the total exploration method by walking along the right and left banks of the river that can be passed on foot. In addition, environmental parameters were also measured, including light intensity, wind speed, soil pH, soil temperature, soil moisture, air humidity, altitude, and air temperature. Based on the results of the study, the ferns found were 6 families with 12 species, both terrestrial and epiphytic. The types of ferns found are Pteris vittata, Pteris ensiformis, Pityrogramma calomelanos, Adiantum lunulatum, Dryopteris marginalis, Pleocnemia conjugata, Christella dentata, Lygodium circinatum, Selaginella willdenowii, Tectaria polymorpha, Pyrrosia piloselloides, and Drynaria quercifolia.

Interview observations were carried out at SMA Negeri 6 Balikpapan and it was discovered that the learning model used still used the conventional model. This is the reason for carrying out this research which aims to find out how student learning outcomes are influenced by the problem-based learning (PBL) model which is assisted by the quizizz application. This study was conducted at SMA Negeri 6 Balikpapan, East Kalimantan, for one month, from April 22 to May 16 2024. The research sample included 32 students, one from each class, because a purposive sampling technique was used. Interviews, observations, tests, and documentation are data collection methods. The research results show that the t table value (2,576) exceeds the calculated t value (1,671) with a significance level of 0.05. The application of the Problem-Based learning model assisted by Quizzizz was able to improve the learning outcomes of Biology students in Class X of SMA Negeri 6 Balikpapan.

n the biology learning process, teachers have used various media and teaching materials such as printed books and student worksheets, supported by teaching media in the form of PowerPoint presentations. The books provided by the school library do not match the number of students, so students cannot take books home to study at home. This research aims to produce a video-based E-Module with material on environmental changes in Phase E that is valid and practical for senior high school Phase E students. This research is an R&D (Research and Development) research using a 4D model which consists of four stages, namely the definition stage, planning stage, development stage, and dissemination stage. This research was carried out to the stage of developing validation tests and practicality tests with descriptive quantitative data analysis and validation tests carried out by 1 Biology teacher, 1 material expert lecturer, 1 media expert, and 1 strategy lecturer. The practicality test will be carried out by 1 biology teacher and 30 students in Phase E senior high school. The research results showed that the validation value carried out by the validator on the e-module was very valid (90.8%), with the practicality test carried out by the Biology teacher on the e-module developed being very practical (91.6%) and by 30 people. Phase E students are very practical (84.3%). From the results of validation tests and practicality tests, it was concluded that the video-based e-module on environmental change material in Phase E senior high school was valid and practical.
