Abstract

Differentiated learning refers to educational schemes and materials individually developed about the varied needs of each student to improve knowledge understanding as individuals, as well as participation involvement. The study applied differentiated learning in the metal inorganic chemistry class of chemistry education to address student understanding variability. These strategies and their effect on student performance were studied through observations, surveys, and interviews in a mixed-method design. The findings portrayed that the application of differentiated learning helps boost the student's performance in understanding the concepts inorganic chemistry of metals. Additionally, the students showed higher satisfactions and engagements when the instructor incorporated different teaching modes, materials (videos, presentation materials, and books), and practical use of examples. Group discussion and collaborative learning among the students helped them better understanding and retention of the knowledge of metal inorganic chemistry

Abstract

Lesson Study is an approach to improving the quality of learning carried out by teachers collaboratively, with the main steps of designing learning to achieve goals, implementing learning, observing the implementation of the learning, and reflecting to discuss the learning studied and improve it and plan the next lesson. The main focus of implementing lesson study is student activities in class, with the assumption that student activities are related to teacher activities while teaching in class. In implementing PPL Education at UNTAD, the implementation of Lesson Study is integrated with the implementation of clinical supervision. The aim is to improve the quality of student learning outcomes and learning products. However, what is still experienced by the world of education today is that more than 50% of teachers do not understand and pay less attention to achieving and improving pedagogical and professional competence, including in schools in Palu City. To teach teachers to implement LS, it is not enough if teachers are introduced to what and how to implement it, but they also need to be introduced to why, what the long-term and short-term goals of implementation are. Teachers also need to be introduced to what the requirements are, what the difficulties and obstacles are in implementation, and that the main requirement for implementation is a commitment to benefit the nation's children. One of the critical characteristics of intelligent humans is that they not only know something but also how to respond and act on it.AbstrakLesson Study merupakan suatu pendekatan peningkatan kualitas pembelajaran yang dilaksanakan oleh guru secara kolaboratif, dengan langkah-langkah pokok merancang pembelajaran untuk mencapai tujuan, melaksanakan pembelajaran, mengamati pelaksanaan pembelajaran tersebut, serta melakukan refleksi untuk mendisukusikan pembelajaran yang dikaji tersebut dan menyempurkannya dan merencanakan pembelajaran berikutnya. Fokus utama pelaksanaan Lesson Study adalah aktivitas siswa di kelas, dengan asumsi bahwa aktivitas siswa tersebut terkait dengan aktivitas guru selama mengajar di kelas. Dalam penyelenggaraan PPL Kependidikan di UNTAD, penerapan Lesson Study diintegrasikan dengan penerapan supervisi klinis. Tujuannya untuk meningkatkan kualitas hasil belajar dan produk belajar siswa. Namun yang masih dialami oleh dunia pendidikan sampai saat ini adalah lebih besar 50% guru yang kurang memahami dan kurang memperhatikan pencapaian dan peningkatan kompetensi pedagogik dan professional, termasuk di sekolah-sekolah yang ada di Kota Palu. Untuk membelajarkan guru melaksanakan LS tidak cukup bila guru dikenalkan pada apa dan bagaimana melaksanakannya, tetapi juga perlu dikenalkan mengapa, apa tujuan jangka panjang dan jangka pendek pelaksanaan. Guru juga perlu dikenalkan pada apa persyaratannya, apa kesulitan dan hambatan pelaksanannya, dan bahwa persyaratan utama pelaksanannya adalah adanya komitmen untuk memaslahatkan anak bangsa. Salah satu ciri kritis manusia cerdas yakni tidak hanya mengetahui sesuatu tetapi juga bagaimana menanggapi dan menindaklanjutinya.

Abstract

The quality of measurement in educational research is highly dependent on the validity and reliability of the instruments used. However, in practice, many numeracy literacy and problem-solving instruments have not undergone adequate psychometric testing, particularly those that use cultural contexts as question stimuli. This study aims to develop and evaluate instruments for numeracy literacy and problem-solving in sequences and series, grounded in cultural context/local wisdom, using a research and development approach and Rasch modeling. The instrument's content validity was assessed through expert review by learning evaluation experts, mathematics education lecturers, and cultural experts (traditional councils). The analysis was conducted using the average validator score, Aiken's V coefficient, and percentage agreement to ensure the appropriateness of the substance, clarity of language, instrument appearance, and the appropriate integration of cultural context. Empirical trials were conducted in small groups with 71 high school students in grade X with 15-17 years in three regions in Indonesia: Palu City, Donggala Regency, and Sigi Regency, who were selected purposively. The test data were analyzed using Rasch modeling to evaluate item suitability, difficulty level, reliability, separation index, unidimensionality, and potential bias through DIF analysis. The analysis results showed that the developed instrument had very high content validity, strong person and item reliability, and that most items fit the Rasch model. However, the distribution of item difficulty did not fully cover the extreme range of respondents' abilities, and indications of DIF were found in some items in one area, indicating the need for further refinement. Thus, the developed numeracy literacy and problem-solving instrument was deemed suitable based on initial findings at the development stage; however, it still requires further revision and testing before being widely used in a more diverse population. Keywords: numeracy literacy, problem-solving, rasch model, reliability, validity.

Abstract

Within the ever-evolving scene of instruction, the usage of differentiated learning, an approach planned to cater to assorted student’s needs, has picked up unmistakable quality. This article investigates the challenges experienced by science teachers as they explore the complexities of joining differentiated learning procedures into their classrooms in junior high schools in Palu, Central Sulawesi-Indonesia. A mixed-methods investigative plan, comprising overviews and interviews, was utilized to explore the encounters of science teachers. The quantitative stage uncovered that whereas a critical parcel of teachers grasped differentiated learning, they experienced challenges such as time limitations (80%), substance adjustment (50%), constraints to fitting educating assets (20%), students’ resistance (30%), and inadequately proficient improvement (20%). The subjective stage gives in-depth experiences into these challenges, highlighting the requirement for imaginative procedures, progressing back, and asset accessibility to overcome them. The consideration underscores the significance of tending to these challenges to cultivate a more comprehensive and locks-in science teaching-learning environment that benefits both teachers and students

Abstract

Pencemaran logam berat seperti timbal (Pb) dalam perairan dapat menimbulkan dampak serius terhadap lingkungan dan kesehatan manusia. Salah satu metode yang efektif untuk mengurangi pencemaran logam berat adalah adsorpsi menggunakan biochar berbasis biomassa limbah organik. Kulit terong belanda Solanum betaceum berpotensi dimanfaatkan sebagai bahan baku biochar karena mengandung selulosa, hemiselulosa, dan lignin. Penelitian ini bertujuan untuk menganalisis kemampuan adsorpsi biochar kulit terong belanda terhadap ion Pb serta mengoptimasi kondisi adsorpsi menggunakan metode Taguchi L9. Biochar dibuat melalui proses pirolisis pada suhu 350°C, 400°C, dan 450°C, kemudian dikarakterisasi melalui analisis kadar air, kadar abu, bilangan iodin, dan morfologi permukaan menggunakan SEM-EDS. Proses adsorpsi dilakukan dengan variasi pH, waktu kontak, dan konsentrasi Pb. Hasil penelitian menunjukkan bahwa biochar memiliki kadar air dan kadar abu yang memenuhi standar SNI, dengan nilai bilangan iodin sebesar 761,4 mg/g yang menunjukkan kemampuan adsorpsi yang baik. Kondisi optimum adsorpsi diperoleh pada pH 4, waktu kontak 120 menit, dan konsentrasi Pb 100 ppm dengan konsentrasi Pb akhir <0,03 ppm. Biochar kulit terong belanda terbukti efektif menurunkan konsentrasi Pb hingga di bawah baku mutu air sehingga berpotensi diaplikasikan sebagai adsorben yang ekonomis, ramah lingkungan, dan berkelanjutan dalam pengolahan limbah logam berat.

Abstract

Pencemaran logam berat, khususnya kadmium (Cd), merupakan masalah lingkungan yang serius karena bersifat toksik, persisten, dan dapat terakumulasi dalam rantai makanan. Penelitian ini bertujuan untuk mengevaluasi kemampuan biochar cangkang pinang (Areca catechu L.) sebagai adsorben ion Cd²⁺ serta menentukan kondisi optimum adsorpsi menggunakan metode Taguchi. Biochar dibuat melalui proses pirolisis dan digunakan untuk mengadsorpsi Cd dengan variasi massa biochar, pH larutan, dan konsentrasi awal Cd. Metode Taguchi diterapkan untuk menganalisis pengaruh parameter dan menentukan kondisi optimum berdasarkan rasio Signal-to-Noise (S/N). Hasil penelitian menunjukkan bahwa biochar cangkang pinang mampu mengadsorpsi Cd secara efektif dengan efisiensi adsorpsi maksimum sebesar 96,98% dan kapasitas adsorpsi 11,64 mg/g pada pH 3, massa biochar 0,25 g, dan konsentrasi awal Cd 100 ppm. Optimasi Taguchi menghasilkan kondisi terbaik pada massa biochar 1,00 g, pH 4, dan konsentrasi awal 50 ppm. Hasil ini menunjukkan bahwa biochar cangkang pinang berpotensi sebagai adsorben ramah lingkungan untuk pengolahan limbah yang mengandung Cd.

Abstract

Konsep terapung dan tenggelam merupakan bagian penting dalam kajian fluida statis yang berkaitan dengan massa jenis, gaya apung, dan hubungan antara berat benda dengan gaya yang bekerja dalam fluida. Meskipun konsep ini sering dijumpai dalam kehidupan sehari-hari, banyak pebelajar masih mengalami miskonsepsi dalam memahaminya. Penelitian ini bertujuan untuk mengidentifikasi bentuk miskonsepsi pebelajar tentang konsep terapung dan tenggelam, mendeskripsikan sumber-sumber miskonsepsi, serta menentukan sumber miskonsepsi yang paling dominan. Penelitian ini menggunakan metode kuantitatif deskriptif dengan subjek penelitian sebanyak 33 pebelajar PGSD Semester 3. Instrumen penelitian berupa tes diagnostik three-tier test yang terdiri atas pertanyaan konseptual, alasan pemilihan jawaban, dan identifikasi sumber miskonsepsi. Data dianalisis dengan mengklasifikasikan jawaban pebelajar ke dalam kategori Scientific, Misconception, Negative False, dan Not Know, kemudian menghitung persentase masing-masing kategori. Hasil penelitian menunjukkan bahwa masih terdapat miskonsepsi pebelajar pada konsep terapung, melayang, dan tenggelam dengan persentase sebesar 12,77%. Miskonsepsi yang muncul umumnya berkaitan dengan pemahaman yang tidak tepat mengenai hubungan antara massa jenis, gaya apung, dan berat benda. Analisis sumber miskonsepsi menunjukkan bahwa faktor yang paling dominan adalah penggunaan intuisi atau dugaan pebelajar dalam menjelaskan fenomena tersebut. Temuan ini menunjukkan pentingnya strategi pembelajaran yang dapat membantu pebelajar merekonstruksi pemahaman konsep secara ilmiah.
