Connecting student interests and questions with science learning goals through project-based storylines

In this conceptual paper, we describe the approach in storylines that builds on principles of project-based learning and focuses on supports for making science learning coherent from the students’ perspective. In storylines, students see their science work as addressing questions and problems their class has identified. We present design principles that guide the teaching and enactment of storyline units and explore the connections of these principles to ideas of project-based science. We illustrate how these design strategies are reflected in a high school biology unit co-developed by teachers and researchers. We present student artifacts that document the agency students take on in this work. We then summarize results from earlier studies examining students’ learning and perceptions of coherence of their learning experiences.

Bimbingan Teknis Penyusunan Bahan Ajar Biologi Berbasis Potensi Lokal Pada MGMP IPA-Biologi Kabupaten Hulu Sungai Tengah

Keberadaan potensi lokal perlu digali sebagai bahan ajar agar proses pembelajaran lebih kontekstual dan bermakna. Keterbatasan pengetahuan guru yang tergabung dalam MGMP guru biologi SMA dan SMP se-Kabupaten Hulu Sungai Tengah memerlukan bimbingan teknis penyusunan bahan ajar biologi berbasis potensi lokal. Kegiatan ini bertujuan memberi bekal dan bimbingan kepada guru-guru biologi sekolah menengah dalam menyusun bahan ajar berbasis potensi lokal. Kegiatan ini dilaksanakan melalui metode ceramah, diskusi, workshop dan konsultasi daring serta penugasan mandiri. Berdasarkan kegiatan yang telah diselenggarakan, diketahui bahwa guru menunjukan antusiasme yang tinggi, sebagaimana terlihat dari proses tanya jawab dan diskusi yang berlangsung sangat dinamis. Banyak guru yang menyampaikan potensi lokal daerah, serta meminta saran dan masukan terkait bahan ajar apa yang dapat dikembangkan. Berdasarkan data yang masuk, terdapat 14 orang guru dari 20 peserta yang sudah mengajukan format pengembangan bahan ajarnya. Dari data 70% peserta yang telah mengajukan format pengembangan bahan ajar ini, menunjukkan peserta telah mendapatkan bekal pengetahuan dan memiliki motivasi tinggi untuk menyusun bahan ajar berbasis potensi lokal sebagai perangkat pembelajaran. Di wilayah Kabupaten Hulu Sungai Tengah memiliki berbagai jenis flora dan fauna, baik yang terdapat di perairan (sungai dan rawa) maupun di daratan. Potensi lokal ini dapat dikembangkan untuk penyusunan bahan ajar Biologi. The existence of local potential needs to be explored as teaching materials so that the learning process is more contextual and meaningful. The limited knowledge of teachers who are members of the MGMP for biology teachers in SMA and SMP in Hulu Sungai Tengah Regency requires technical guidance in preparing biology teaching materials based on local potential. This activity aims to provide provision and guidance to high school biology teachers in preparing teaching materials based on local potential. This activity is carried out through lectures, discussions, workshops, online consultations, and independent assignments. Based on the activities that have been held, it is known that the teacher shows high enthusiasm, as can be seen from the very dynamic question and answer process and discussion. Many teachers convey the local potential of the area and ask for suggestions and input regarding what teaching materials can be developed. Based on the incoming data, 14 teachers from 20 participants have submitted the format for developing their teaching materials. The data of 70% of participants who have proposed this format for developing teaching materials shows that participants have gained knowledge and have high motivation to develop teaching materials based on local potential as learning tools. The Hulu Sungai Tengah Regency has flora and fauna, both found in waters (rivers and swamps) and on land. This local potential can be developed for the preparation of Biology teaching materials.

PENGEMBANGAN MODUL BIOLOGI SMA KELAS X BERBASIS ETNOBOTANI MASYARAKAT KEDIRI DAN SEKITARNYA UNTUK MENINGKATKAN HASIL BELAJAR SISWA

The purpose of this study is to produce high school biology modules based on the ethnobotany of the people in Kediri and its surroundings to improve student learning outcomes. The development research used the Borg and Gall model which was tested on students of SMAN 1 Plemahan. Based on the results of the material expert validator's assessment, the percentage is 98.82%; according to development experts by 80%; according to media experts by 88%; and according to user experts the percentage is 95.25%. The results of the four expert validators are each at a very valid level. The results of the practicality test are 97.5% and interpreted in the very practical category. The results of the effectiveness test have an average N-gain of 0.58 with moderate criteria in the category of quite effective for improving student learning outcomes.

PENGARUH PERENDAMAN JENIS BUAH TERHADAP PENURUNAN KADAR KADMIUM (Cd) PADA UDANG VANNAME (Litopenaeus vannamei) TAMBAK INTENSIF DEKAT DAN JAUH MANGROVE

Vanname shrimp (Litopenaeusvannamei) has filter feeder properties that can filter all the food contained in the sediment. Cd is a type of metal that will settle in the sediment. Cd can accumulate in the shrimp body and endanger human health if consumed. The objectives of study were 1) to determine the effect of immersion of fruits on the reduction of Cd levels, 2) to determine which types of fruits were more appropriate to reduce Cd levels in Vanname Shrimp in remote and intensive ponds. near mangroves and 3) to make posters as learning media for class X high school on environmental pollution. The research was conducted using the CRBD method (completely randomized block design) and analyzed with a one-way anova test to determine the effect of fruits on the reduction of Cd levels. The research was conducted in April 2020 in Pasir Sakti, East Lampung and analyzed at the Chemical Analytical Laboratory of the Muhammadiyah University of Malang. The results showed that soaking vanname shrimp using fruits had the effect of reducing Cd levels in shrimp meat. The type of fruits that gave the best reduction effect was Citrus aurantiifolia which was able to reduce the Cd to 270.87 ppb or decreased by 46.28% for intensive pond shrimp near mangroves, and able to reduce the Cd to 521.4 ppb or decreased by 44.62% for intensive mangroves distant pond. This research produces learning resources in the form of posters that are suitable for use in class X high school biology learning environmental pollution material.

Kelayakan Buku Panduan Lapangan “Keanekaragaman Pohon di Lingkungan Kampus Universitas Lambung Mangkurat” sebagai Sumber Belajar Mandiri Konsep Keanekaragaman Hayati

The environment is a natural laboratory that presents unique phenomena that humans must study. Plants in the surrounding environment can be used as learning resources and media to bring students closer to their learning objects. Learning by utilizing objects in the surrounding environment can help the learning process. The diversity of tree in the Lambung Mangkurat University campus can be used as a source of learning and support learning based on the concept of diversity. One of the learning media that can be developed is a field guide book to guide users when learning independently in the environment. This study aims to describe the validity of the results of the development of a field guide "diversity of trees in the Lambung Mangkurat University campus". The feasibility of the field guide book was obtained from two experts and one high school biology teacher. The results of the validator's input and suggestions become material for correction and revision of learning products. The results of the field guide book validation show that the product is very valid and theoretically or procedurally feasible to be used for implementation at a later stage.
