A Thematic Review on Exploring Ethnoscience in Science Education: A Case in Indonesia

This study aims to review the ethnoscience studies in science education in Indonesia thematically. From 2010 to 2020, the databases contained 71 relevant articles of ethnoscience studies. These studies belonged to the content analysis theme parameters of method/design, sample, data collection, data analysis, topic, result, recommendation, and location. The results indicated that most of the ethnoscience studies explored the effect of integrating ethnoscience with the lessons to investigate students’ achievement and attitudes towards science. Correspondingly, the investigated studies mostly used Research and Development (R D) and experimental research design. The preferred data collecting techniques were tests (multiple-choice/description), questionnaires, and observation. Moreover, seventh and eighth graders of junior high school commonly employed the argumentation activities in physics, chemistry, biology, and basic concept of science topics. This study suggests the teachers employ different methods (e.g., ethnoscience) to improve concept understanding, problem-solving skills, critical thinking skills, and motivation in learning science from the primary school level. Furthermore, resources from cultural activities in Indonesia are beneficial for integrating ethnoscience in learning.

Self-evaluation and observation: A proposal to promote CLIL teacher training at Infant Education

The Bilingual Program of the Community of Madrid (BPCM), Spain, started offering Content and Language Integrated Learning (CLIL), in English, at Primary Education in 2004, at Secondary in 2010, and at Infant Education (3–6-year-old students) in 2017. This approach requires multiskilled practitioners, highly trained in the CLIL methodological principles, to ensure the planning and delivery of effective lessons. However, CLIL teacher training is deficient and needs to be boosted through alternative proposals. This work analyses the potential of a checklist for self-evaluation and observation of CLIL teachers at Infant Education. It is an exploratory research that presents a case study in two Infant Education classrooms in which CLIL is taught by the same teacher. The data collection includes linguistic data collecting techniques such as the checklist for the observer and for the teacher, an observation protocol, transcripts of the interviews, among others. Results from the qualitative analysis of the Infant teacher self-evaluation and the observer showed that a never-ending-teacher-development-awareness to promote teachers to manage their experience adequately was stimulated, and it was likely to open the door to innovation in educational trends (CLIL) in order to offer a solid respond for their professional needs. It also proved to identify the actual CLIL training needs of the Infant teacher and unveiled her thoughts and practice in her bilingual classes. Therefore, it can be concluded that the self-evaluation checklist can be a useful instrument likely to shed some light on the complex phenomenon of in-service CLIL teacher training.

A simple, low-cost device for collecting mushroom-dwelling Scaphidiinae (Coleoptera, Staphylinidae)

The shining fungus beetles (Coleoptera: Staphylinidae: Scaphidiinae) comprise more than 1800 described species, which are usually small (≅0.84–14.30 mm long) (Tang et al. 2014 ; Löbl & Ogawa 2016) and found on bracket and resupinate fungi, mushrooms and slime molds (Newton 1984; Löbl & Leschen 2003; Löbl 2018). They are known to be diverse in forests of tropical and subtropical regions, which contrast to the low number of species currently known from Brazil: only 34 species and two subspecies from seven genera (Löbl 2018; von Groll & Lopes-Andrade, 2021). Any active search for Scaphidiinae in the Brazilian Atlantic forest reveals a considerable abundance and diverse of these organisms (pers. obs.), but they disperse rapidly if disturbed, and the success of field collections relies on the collectors’ skills, luck and collecting techniques and devices. The most common methods and devices for collecting shinning fungus beetles are sifting leaf litter, rotten wood and fungi, flight intercept (FIT) and V-flight intercept (V-FIT) traps, aspirators, sweeping, and hand collecting (Löbl & Leschen 2003; Tang et al. 2014; Löbl et al. 2021). Hand collecting is considered the best method, because the host fungi and larvae can be collected together to make associations (Löbl & Leschen 2003).

The Potential of Jenderal Soedirman's Short Film as Learning Media in National Events of the Colonial Period’s Material for Fifth Graders: A Semiotics Analysis

The stories of Jenderal Soedirman, one of the national instrumental figures in seizing Indonesia's independence from the invaders, have been visualized in many films. Films containing events about the struggle for independence need to be studied, understood and remembered so that the values of nationalism are embedded. This film has the potential to be used as a learning media in packaging stories into interesting and meaningful learning for elementary school students. This leads researchers to analyze Jenderal Soedirman’s short film as learning media on the IPS national events of the time colonization of 5th graders of elementary school. This study used a qualitative approach in observing an individual behavior and to describe the data of research’s findings in detail and moderation. The research method used was Roland Barthes’s semiotic analysis that focused on signs and symbols as markers interpreted by denotation, connotation and myth on the film. The data collecting techniques used were observation, student's journal, questionnaires and documentation. Based on research and discussion of semiotic analysis of Jenderal Soedirman’s short film as learning media on three meanings, it is evident that researchers can better understand the hidden meaning contained in the film. The researchers deeply identify the figure of Jenderal Soedirman, the myth believed by the Indonesian freedom people during his struggle and this film potential to be used as a learning media because it increases students’ learning motivation by a score of 3,00 earned in a reasonably good category.
