According to the results, the STEM application was effective on the scientific process skills of the prospective teachers in the experiment group in comparison to those in the control group; however, it was not effective on their levels of orientation towards STEM education. The prospective teachers stated that Algodoo is a good tool for integration of STEM disciplines.

Models and the Nature of Science: What Mediates Their Implementation in Portuguese Biology and Geology Classes?

Currently, it is considered fundamental to improve students’ views of the nature of science (NOS) in science classes. In addition, models are also important in science education, not only as contributors for students to develop their views of the NOS, but also for them to develop conceptual knowledge, as well as inquiry skills. Teachers greatly influence students’ learning experience. With the aim to improve prospective science teachers’ views of the NOS and about models, and to better understand the factors that mediate the translation of their views into their classroom practices, a research project was conducted. An intervention programme was applied, and prospective science teachers’ classes were observed. Data were collected, encompassing a diverse set of data sources: (i) questionnaires and interviews (given to prospective science teachers before and after the intervention programme); (ii) prospective science teachers’ lesson plans and portfolios: (iii) videotapes and observations of the classroom instruction; (iv) and, lastly, final interviews were given to both prospective science teachers and their school supervisors. Although prospective science teachers have improved their views regarding the NOS and models, they taught about the NOS and used models in very different ways. Some factors that mediate the translation of teachers’ views and some educational implications will be discussed.

POTENSI INTEGRASI KEARIFAN LOKAL DAYAK DALAM PEMBELAJARAN ILMU PENGETAHUAN ALAM DI SEKOLAH DASAR KOTA PALANGKA RAYA

The focus of the study was to identify the nature of worldview held by candidate science teacher, and explores the relationship, if any, between their worldview and their conception of nature of science. In addition, the implication of this relationship for science teaching and learning are discussed. Participants were 30 Dayak prospective science teachers. Their conception of nature f science and their worldview specific to humans’ relationship with the natural world were assessed using a questionnaire in conjunction with follow up interviews. The results show that 70% of the participant, irrespective to their cultural backgrounds, hold the nature centric worldview, while 30% of them have the anthropocentric worldview. And the interview result confirm that participants possessed narrow view about the nature of science, where they described science as based on facts only, core on observation, no creativity and tentative due to the change of facts. The study suggests the need to for incorporating sociocultural perspectives and nature of science in the curriculum.

Determination of Prospective Science Teachers' Level of Knowledge about Thermodynamics and Their Reasoning with Daily Life Examples

The aim of this study was to determine the relationship between environmental problems and thermodynamics of prospective science teachers. The study was conducted with the case study method. The sample consists of 74 senior prospective science teachers studying in Science Teaching Department in the faculty of education of a state university in Turkey in spring semester of 2018-2019 academic year. The first part of the data collection tool consisted of four open-ended questions and it was the form in which the prospective science teachers were asked to explain the laws of thermodynamics. In the second part of the data collection tool, there were eleven open-ended questions which were expected to be explained by the laws of thermodynamics of the given environmental problems. As a result of the study, prospective science teachers were found to have difficulty applying any laws of thermodynamics to a daily event or environmental problem.

Determination of the Opinions of Prospective Science Teachers About Biology Lessons Taught Through Distance Education

This paper aims to determine the opinions of prospective teachers about biology lessons conducted through distance education during the pandemic. In the study, the focus group study technique was applied as one of the qualitative research methods. 15 prospective teachers from the Department of Science Education, studying in the 2nd, 3 rd, and 4th -grades in Siirt University, participated in this study. Questions were presented to the prospective teachers in the form of a semi-structured form and interviews were conducted separately for each grade and recorded. The data collected were analyzed via content analysis. Based on the findings of the study, the prospective teachers stated that they had internet-related and technical problems and they also failed to follow biology lessons due to their unsuitable home environment and ineffective communication processes. It was understood that the vast majority of prospective teachers preferred face-to-face evaluation rather than e-evaluation. To make biology lessons more efficient, it was recommended that prospective teachers should be obliged to attend classes, YouTube videos and animations should be added, classroom or laboratory lessons should be organized, WhatsApp groups should be created and question section should be added through these groups, and lessons should be synchronous rather than asynchronous.

ANALYSIS OF STUDENTS' ABILITY TO IDENTIFY SYMBOLIC REPRESENTATIONS IN CHEMISTRY

To describe the behavior of matter and energy, chemists classify them in three distinct domains: macroscopic, microscopic, and symbolic. The ability to use these three representations is the basis for understanding concepts in chemistry. This study aims to analyze students' ability to identify symbolic representations in chemistry. The research design uses a one shot case study. The subjects of this study were students of prospective science teachers as many as 85 students. Data collection techniques using tests and rubrics. The results showed that of the ten symbolic representation statements, only three statements achieved the highest percentage of correct answers, namely statements about writing ionization reactions and writing electron symbols. There are two statements where almost 90 percent of students answered incorrectly. The statement is about reversible or irreversible reaction equations and exothermic reaction equations. From this research, it can be concluded that students' ability to identify symbolic representations in chemistry still needs to be improved, because the average score is still low.

Integration of IBL and CLIL in Preparing Prospective Teachers for Teaching Natural Sciences in Multilingual Environment

Introduction. The relevance of the problem of preparing prospective teachers of natural sciences for teaching in several languages is determined by the social need of society. Insufficient practical training of young specialists requires the search for effective methods to help solve the problem. The aim of the research was to study the impact of the integration of IBL and CLIL methods on the quality of prospective teachers’ preparation to teach science subjects (taking Chemistry as an example) in English. The integration of CLIL and IBL methods is proposed to prepare prospective teachers of natural sciences for teaching in English which serves as a foreign language in a multilingual environment. Materials and Methods.Using the methods of pedagogical experiment, observation, testing, analysis of lesson recordings, descriptive and mathematical statistics, prospective science teachers’ speech acts as indicators of effective training were analyzed during the period of pedagogical apprenticeship. The research was carried out before and after learning in two groups of students studying with application of the CLIL method (control group) and the integration of IBL and CLIL (experimental group). Results. Obtained results demonstrate the non-random pattern of the changes between the two groups of students. Experimental students expressed more directives. A significant increase was observed in high-level questions at the stages of lessons with the organization of independent student research. The types of directive acts have become more diverse than in the control group. The integration of the CLIL and IBL methods had a positive effect on the growth of indicators of the quality of student preparation. Discussion and Conclusion. The presented results can be used to prepare prospective science teachers for teaching subjects in any second language. The results will be relevant for university lecturers in European and CIS countries who are looking for effective ways to train multilingual teachers.
