Many studies have demonstrated the effectiveness of formative science assessments, which were utilized in education in many industrialized nations as recently as two decades ago. The adoption of formative assessment procedures in Indonesia has, however, fallen short of expectations due to a number of factors, including the teachers' lack of understanding, preconceptions, and various challenges. Using an exploratory descriptive qualitative methodology, this study aimed to establish how teachers understand and perceive formative assessment, as well as the various implementation issues they experience in the classroom. Chi-square analysis was utilized to determine the correlations between the ordinal variables. The data were gathered through an online survey followed by interviews with five teachers possessing various profiles. It was determined that teachers' conceptual understanding and perceptions of formative assessment fell into the "fairly good" category, demonstrating that they had a clear understanding of the concept and favorable perceptions of it. There was significant evidence of the relationship between training and comprehension and between comprehension and the frequency of applying formative assessments in science learning. However, the teachers admitted that they had not regularly used formative assessments in the classroom. The biggest challenges, according to teachers, were too many students, a lack of time, a lack of practical knowledge, and insufficient or inappropriate training.

This research was applied to the project learning model of supporting learning materials at high school SMAN 3 Jambi City. The learning model in the 2013 curriculum must fulfill the five steps scientific approach namely Observing, Asking, Experimenting, Collecting data, and Communicating, which is the goal of a learning model like this to make students understand learning well, educational design-based research that adopts the substance of the formative evaluation type with the characteristics of substance experts in procedural assessment, one-on-one evaluation, small group evaluation and field presentation. The concept of formative evaluation can be integrated with research and development method. The Project Based Learning (PjBL) model in Buffer Solution was using a development process type with a hybrid theory-based approach and directing eight-step practice. The theoretical steps are identifying data sources, collecting data and analyzing data, while the practical steps are generating model ideas, describing models, validating concepts and practitioners and formulating recommendations for testing models. The product was validated by a team of experts which includes practitioner validation to see the practicality of using the product being developed. A small group test was carried out to see the application of the product being developed. The results showed that learning chemistry using the PjBL model could increase the activity and results of students' chemistry learning on the concept of buffer solutions. The increase in student chemistry learning outcomes in the buffer solution concept can also be observed based on the value in general of the learning outcomes obtained by students in cycle I of 68.09 increased to 74.81 in cycle II and % completion in the classical way from 39.39 percent increased to 87.88 percent and this fulfills the marker of success is classical completeness reaching 85 percent with Minimum Completeness Criteria of 70.

Multidimensional Impact: Environmental Degradation in Nigeria

2023-02-01T01:33:11+00:00

Over the years, the Nigerian government has not given the necessary attention to environmental problems. As a result, environmental resources have suffered the consequences for decades and this remains one of the most complex problems in Nigeria. This study aims to describe the multidimensional impact of environmental degradation in Nigeria. This research was conducted qualitatively using a descriptive research design. The data analysed in this study were obtained from secondary sources in the form of books and scientific journals that were published and were relevant to the topic discussed. This study shows that environmental degradation is a major problem that must be addressed by all levels of Nigerian society. This study presents several recommendations that can be implemented to improve environmental management in Nigeria.

Technological Pedagogical Content Knowledge (TPACK): Survey Persepsi pada Mahasiswa Calon Guru IPA

2023-03-06T12:30:09+00:00

Technological Pedagogical Content Knowledge (TPACK) refers to a combination of three crucial elements: pedagogical knowledge, content knowledge, and the integration of technology used by teachers in the learning. TPACK knowledge is needed to improve the quality of pre-service science teachers. This study aims to describe the perceptions of pre-service science teachers regarding TPACK knowledge. This research was survey research using a quantitative descriptive method involving 60 students at Universitas Tidar. Data were collected using a self-assessment questionnaire containing 31 items that include 7 (seven) TPACK indicators, namely Content Knowledge (CK), Pedagogical Knowledge (PK), Technological Knowledge (TK), Technological Content Knowledge (TCK), Pedagogical Content Knowledge (PCK), Technological Pedagogical Knowledge (TPK), and Technological Pedagogical Content Knowledge (TPACK). Data were analyzed within 3 (three) stages, i.e. data reduction, data display, and drawing conclusions. Furthermore, the data were converted into qualitative assessment criteria to describe the perceptions of pre-service science teachers. The results showed that the TPACK knowledge of pre-service science teachers was categorized as good. The findings are expected to be a reference in improving the education program.

Pengembangan Media Pembelajaran Mobile Learning Berbasis Android Pada Pembelajaran IPA di Kelas VIII SMP/MTs Tema Makananku Kesehatanku

2023-02-10T01:18:48+00:00

This research was conducted because of the difficulties experienced by students in learning, especially in the use of learning resources, teaching materials, or learning tools in the classroom. The conclusion of the interview with the resource person, namely the eighth grade science teacher, was that the learning resources available at school, especially for natural science learning, are still very minimal. Student books, student worksheets, and power points are still often used by teachers to deliver learning materials. WhatsApp is one of the technological intermediaries that students must use to learn independently during pandemic conditions, so students do not understand the material presented, especially science. This affects the process, objectives, and learning outcomes of students. In addition, the delivery of learning materials has not been integrated, so it takes a long time to develop one basic competency. The purpose of this study is to determine the validity of android-based mobile learning media for science learning in grade 8 (grade eight) junior high school or MTs with the theme of "my food, my health." The Borg and Gall R&D model was adapted by Sugiyono and modified by the author into five stages, including potential and problems, collecting data, designing products, validating product designs, and improving final product designs. Based on the results of data analysis, the expert validation score is included in the "very valid" category and can be used in science learning, with a percentage of findings of 84% from the results of material validation, 84.8 percent from media validation, and 86.6 percent from teacher assessment.
