Pre-service Science Teachers’ Competence and Confidence in Scientific Inquiry

The quality of science learning has a very important role in science education. The quality of science learning is largely determined by the quality of science teachers. Inquiry-based science learning is becoming a model that must be developed today. In order for inquiry-based learning to be carried out properly, science teachers must have adequate inquiry competencies. Teachers must also have adequate confidence in conducting inquiry-based learning with students in the classroom. The objective of this study was to examine students’ competence and confidence in scientific inquiry. 42 pre-service science teachers were involved in this study. Data collected were analyzed using Rasch modeling. The results of data analysis show that mean of the Rasch score for students’ competence (1.76 Logits; SD = 1.20) is higher than the mean of the Rasch score for students’ confidence (1. 41 Logits; SD = 1.01). These results show that although students feel competent to do inquiry, they do not yet fully have the confidence to carry out inquiry learning with students in classroom activities. Implications for a science teacher and pre-service science education based on these results are discussed.

Persepsi Pendidik terhadap Pembelajaran IPA secara Terpadu di SMP/MTs Kota Banda Aceh

Based on the Curriculum 2013, science learning in junior high schools is provided in an integrated way. However, the quality of science learning in fact is not encouraging. This is evidenced by science learning achievement in Indonesia is categorized as still low based on National Examination. The recent studies found that teachers conducted integrated science matter separately. This approach requires the ability of teachers, whereas not all science teachers in SMP/MTs are prepared from science education. This research was conducted in Banda Aceh. The research objective is to identify the teacher's perspective regarding integrated science based on teacher knowledge. This research uses descriptive qualitative research with questionnaire and semi-structured interviews. Data collection was carried out by proportional stratified random sampling. Respondents in questionnaire filling were 105 science teachers and in the interview were 21 people. The data analysis techniques are data collection, data reduction, data display, and conclusion drawing. The results showed that based on the teacher's perspective on integrated science, there is a high awareness of creating an effective teaching and learning environment for students regardless of the out of scientific field that is not linear according to sarjana pendidikan IPA. Subject matter of teachers is relevant to understand the concepts in integrated science which are interconnected with each other which continues to be strengthened for professional development.

Penyusunan Spesimen Awetan Tumbuhan dan Hewan Di SMPN 20 Mataram

Abstract: The Biology Science Practicum has a role in improving the quality of science learning, especially Biology material, as well as improving science process skills and students' understanding of science concepts. The Biology Science Practicum requires the availability of plant and animal specimens as the main object of observation, but this is not widely available in the Science Laboratory of SMPN 20 Mataram, thus causing the Biology Science practicum not to be carried out properly. The purpose of this community service is to increase the understanding and skills of teachers to make specimens of preserved plants and animals. The method of implementing community service was to provide training for teachers to make specimens of preserved plants and animals which was conducted in September 2020. The training was guided by lecturers, education staff (laboratory assistants), and students. Questionnaires were given to training participants to evaluate the effectiveness of community service programs. The result of the training was that there were twenty teachers who came from science teachers and other subjects involved in training in making insectariums, herbariums, Mollusca shell preserves, and animal wet preserves, and participants responded that the training had increased the knowledge and skills of teachers in making plant specimens and animal. The conclusion is that the training carried out by providing samples of preserved specimens of living things, demonstrations and assistance in making preserved specimens have an impact on increasing participants' understanding and skills in making preserved specimens of plants and animals. Keywords: Dry and wet preservation of living things; Herbarium; insectarium; Biology practicum; Plant and animal specimens.
