Abstract

Students’ beliefs toward conspiracy theory (CT) of COVID-19 can be the indication of science education quality. However, a validated instrument to measure the level of students’ acceptance on the CT about COVID-19 still remains unexplored. This study aimed to evaluate the questionnaire of CT about COVID-19. The questionnaire consisted of 14 items and delivered online to the 400 students of Biology education in Indonesia. The data was analyzed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). All items have standard deviation between 1.60 and 2.63, but one item was revealed to have insignificant correlation. The EFA result indicated that the other 13 items had loading factor 0.5 and were categorized into three dimensions. The third dimension was eliminated after the administration of CFA due to only one item in the dimension (λ>0.5). There were three items in the first dimension and two items in the second dimension resulted in λ<0.5. The correlated model from CFA disclosed good values of goodness of fit (GOF), χ2/df=2.527, root mean square error of approximation (RMSEA) standardized root mean square residual (SRMR)=0.014, comparative fit index (CFI)=0.964, goodness-of-fit index (GFI)=0.969, adjusted goodness of fit (AGFI)=0.940, Tucker-Lewis index (TLI)=0.947, and normed fit index (NFI)=0.943. Therefore, the questionnaire is strongly recommended to measure the level of students’ beliefs toward the CT of COVID-19.

Abstract

Apart from the importance of scientific literacy for the pre-service teachers as the key to success in becoming a teacher who can teach and make literate students, not many studies have revealed the contributing factors, especially the learning experience students. This study aims to measure the level of scientific literacy skills of pre-service students and contributed factors. One hundred and five students at state Islamic universities in Indonesia participated in this study. The data were collected in three stages. First, the level of scientific literacy skills using the Test of Scientific Literacy (TOSLS). Two students with the highest and lowest abilities in each batch were interviewed. Finally, the semester learning plan (RPS) and practicum instructions are reviewed. The mean was used to describe the level of scientific literacy skills, and one-way ANOVA to test differences in skill between the four groups based on the spent year in university. Data obtained from interviews and analysis were analyzed using content analysis techniques. As a result, pre-service biology teachers have a "medium" level of scientific literacy skills. There was a difference between the four groups with the highest and most significantly different fourth-year students. The primary cause of scientific literacy skills is the student learning experience in terms of learning strategies, assignments, evaluations, and practicums activities that are obtained by pre-service biology teachers. The results suggest the following implications for teaching: faculties must identify scientific literacy skills and carry out learning with learning strategies, assignments, evaluations, and practicum activities that support the growth of scientific literacy abilities of a pre-service biology teacher.

Abstract

Indonesia, as a mega biodiversity country, has various types of wild plants. Sempolan Village, part of Jember Regency, has fertile land to support the growth of a wild plant. This research investigates wild plants used as food sources by indigenous peoples in Plalangan, Sempolan Village. This study also conducts data on how wild plants were cooked, served, and enriched by nutrition notice. The method is qualitative descriptive analysis obtained from observation, interview, documentation, and literature study. So, research results found 26 species and grouped them into 19 families. In addition, the locality of these species is in yards, fields, and roadsides. The habitus identified is an herb (77%), tree (11%), shrub (8%), and liana (4%). Those foods categorize into 1) carbohydrates sources, 2) vegetables, and 3) fresh fruits. The carbohydrate sources mostly served as a side dish, compote, and flour by stewing and frying. The vegetables include 18 species served as complements of the main menu, which cooked for soup, curry, stir fry, ointment, and pothok. Fresh fruits comprise of 4 species were directly consume or make a salad. Furthermore, all food resources contain essential nutrients like vitamins, macro and micro minerals, and phytochemicals that are important for society's growth and healthy lives. Finally, Information on wild plants as a food source will increase food diversification as well as dishes.

Abstract

Penelitian ini dilakukan dengan tujuan untuk meninjau efek pembelajaran inkuiri terbimbing pada keterampilan proses sains peserta didik dalam pembelajaran sains. Metode penelitian yang digunakan yaitu kuantitatif meta-analisis dengan sampel terpilih sebanyak 13 artikel pada jurnal terakreditasi nasional. Pemilihan artikel didasarkan pada beberapa kriteria kelayakan: (1) harus memiliki nilai mean dan standar deviasi; (2) subjek siswa SD, SMP, dan SMA; (3) pelaksanaan pada pembelajaran sains. Variabel meta-analisis yang digunakan adalah jenjang sekolah (SD, SMP, dan SMA) dan mata pelajaran (IPA, Fisika, dan Biologi). Hasil meta-analisis menunjukkan bahwa penggunaan inkuiri terbimbing paling berpengaruh terhadap keterampilan proses sains peserta didik pada jenjang SMA, sedangkan dari subjek mata pelajaran inkuiri terbimbing memiliki pengaruh terbesar pada keterampilan proses sains di mata pelajaran fisika. Namun baik dari jenjang pendidikan maupun mata pelajaran keseluruhannya menunjukan pengaruh yang positif dari inkuiri terbimbing terhadap keterampilan proses sains. Hasil penelitian dapat diterapkan pada pembelajaran dengan permasalahan serupa yaitu terkait keterampilan proses sains peserta didik.
