Perceptions of Pre-service Science Teachers in Indonesia about the Greenhouse Effect (GHE)

Tackling climate change is one of the Sustainable Development Goals (SDGs) and concerns the world community. The greenhouse effect (GHE) is the primary source of global warming and influences climate change. This exploratory research aims to explore the perceptions of pre-service science teachers in Indonesia about the GHE. The study's participants were 265 Indonesian pre-service science teachers. Research data was collected through a questionnaire. The questionnaire consists of three open questions and 36 statements with multiple-choice responses. The open-ended inquiry is coded, and the resume is shown as a mind map. The remaining questionnaire results were examined using descriptive statistics. Based on the analysis results, it can be concluded that most prospective teachers have not been able to describe the process of GHE in detail, and there are still several misperceptions. Prospective teachers must have the correct perception of the topics they will teach their students in the future, so the implications of this research are recommendations for institutions and teaching lecturers in teacher education to discuss GHE topics in more detail and ensure there are no misperceptions.

Determining pre-service science teachers’ perceptions of science, nature of science, and the relationship between them

Besides being a necessity for science education, understanding the nature of science and the concept of science also facilitates individuals’ daily lives and affects their decisions as conscious citizens. This study aims to determine the pre-service science teachers' perceptions of science and their views on the nature of science and the relationship between them. The study was carried out with prospective science teachers from different undergraduate levels. Perception of Science Questionnaire and Views on Nature of Science Questionnaire were used as data collection tools. The views on the nature of science were coded as unacceptable, partially acceptable and acceptable and statistical analyses were carried out accordingly. Pre-service science teachers’ views on the nature of science were found to be unacceptable and partially acceptable. Nature of science views generally showed a positive tendency throughout the undergraduate education. The metaphors obtained from the concept of science were analyzed by content analysis. The metaphors obtained were categorized as dynamic, guiding, cumulative, requirement andinfinite. According to the results, the perceptions of pre-service science teachers were positive, but also showed some deficiencies and misconceptions. Finally, pre-service science teachers’ choice of metaphors, although not statistically significant, differed according to their grade level. No statistically significant relationship was found between pre-service science teachers' views on nature of science and their perceptions of science.

Analysis of Environmental Risk Perceptions and Scores of Preservice Science Teachers in Terms of Some Variables

This research aims to determine the environmental risk perceptions of preservice science teachers (PSTs) and compare their risk scores in relation to different variables. The research participant group consisted of PSTs (N = 205) from the Faculty of Education in the Department of Science Education at Bolu Abant İzzet Baysal University in Turkey. The environmental risk perception scale (ERPS) was used as a data collection tool and the environmental risk perception interview form (ERPIF) was used during the interviews. A survey model was used in the research. An enriched design in which quantitative and qualitative analyses were used together was included. Quantitative results from the research show “radiation,” “factory waste,” and “hazardous (chemical) waste,” as environmental problems that PSTs consider the riskiest. The least risky environmental problems were “overgrazing of animals in meadows and pastures,” “commercial fishing,” and “open mining.” According to the qualitative interview results, “air pollution” and “factory waste” were seen as the riskiest environmental problems, while “environmental waste” was considered the least risky environmental problem. In addition, while the females had a higher environmental risk perception than the males, there was a significant difference between the 3rd and 4th levels with 4th level PSTs favoring a higher environmental risk perception. There was no significant difference between the environmental risk perception scores of the PSTs depending on whether they took an environmental course or not; neither was there any significant difference issuing from the educational status of PSTs’ parents.

The Perceptions of Pre-Service Science Teachers and Science Teachers about Climate Change

<p>The global climate phenomenon in the context of climate change is the impact of both the dynamic complex climate system and human behaviors that affect environmental sustainability. Human is an important component that should be considered in science teaching that is believed to improve human attitudes towards the environmental sustainability. The research aims to investigate the perceptions of pre-service science teachers and science teachers in South Sumatra who teach climate change and global warming. The data were collected from 17 science teachers and 53 pre-service science teachers from April to August 2016. The instruments were 17 modified questions which were developed from Pruneau’s framework. There are three linear perceptions regarding climate change. First, greenhouse effect causes global warming and global warming causes climate change. Second, ozone leakage causes global warming and global warming causes acid rain. Third, greenhouse effect causes ozone leakage and ozone leakage causes global warming; then it causes climate change and other climatic phenomena. Both pre-service science teachers and science teachers argue that climate change is caused by global warming. Actually, climate change is not only global warming but also global cooling. Those phenomena occur because of interactions among climate system components. They do not believe that education is able to change human attitudes in saving environmental sustainability from global climate change disasters. They believe that media give stronger effects than teachers in shaping those perceptions. Factually, most of wrong perceptions come from media.<br /><br /><br /><br /></p>

Determining the perceptions of pre-service science teachers regarding environmental problems through word association

In this study, Word Association Test (WAT) was administered to 123 people in order to determine the perceptions of pre-service science teachers regarding environmental problems. “Environmental Problems” was given as a key word to the pre-service teachers, and they were asked to write what came to their minds on WAT and make one sentence about this concept. The responses concerning the key word were examined under six themes: “causes”, “effects”, “types”, “measures”, “worry/pessimism”, and “other”. The pre-service teachers were seen to have stronger cognitive structures about the causes of environmental problems in comparison to other themes. Most participants confused the concepts of environmental problem and environmental pollution. They mostly focused on the effects of environmental problems on human beings and had worry and pessimism. Emphases laid by the pre-service teachers on environmental awareness, consciousness, and love in regard to the measures that can be taken against environmental problems demonstrate that they think education is important for the solution of environmental problems. The research results reveal that perceptions regarding environmental problems are not adequate among the pre-service science teachers. This lack of perception among the pre-service science teachers, who are to play an important part in raising environmental awareness, can be eliminated only through an effective environmental education. Keywords: Perception of Environmental Problems, Environmental Education, Science, Word Association, Pre-Service Teachers

Perceptions and Competence of Turkish Pre-service Science Teachers with regard to Entrepreneurship

The aim of this study is both to determine the perceptions of pre-service science teachers towards the concepts of entrepreneurship and entrepreneurial characteristics and to investigate the perceptions of pre-service science teachers regarding transferring the entrepreneurial characteristics to students. This study is designed as a qualitative study and a phenomenological research approach is used. A total of 12 pre-service science teachers from grades 5 to 8 participated in the study. Data were gathered through the use of semi-structured interviews. The data were evaluated through both descriptive and content analysis. The results show that the perceptions of the 12 pre-service science teachers indicated a limited and inadequate understanding of the concept of entrepreneurship, based on their interviews. From these results, it can be said that there is a need to develop educational content in such a way as to increase pre-service science teachers’ knowledge and experience with regard to entrepreneurship in science teacher training.

Development of a TPACK Self-efficacy Scale for Preservice Science Teachers

Today, it is of great importance that teachers have pedagogical and technological knowledge in addition to content knowledge. For this reason, the present study aims to develop a TPACK self-efficacy scale for preservice science teachers by following the theoretical framework of technological pedagogical and content knowledge (TPACK), as suggested by Koehler and Mishra (2006). The scale consists of seven subscales, which are technology knowledge (TK), pedagogy knowledge (PK), content knowledge (CK), technological pedagogical knowledge (TPK), technological content knowledge (TCK), pedagogical content knowledge (PCK), and technological pedagogical content knowledge (TPCK) with a total of 55 items. A total of 467 preservice science teachers from four different universities in Turkey participated in the study. The Cronbach's alpha reliability coefficient of the scale was calculated as 0.969. Following the modification suggestions, confirmatory factor analyses showed that the model fit the scale adequately. The study found significant differences between the bottom and top groups; this shows the sufficiency of the items’ discriminatory powers. As the result of these analyses, it was found out that the scale had the necessary properties required for measuring the TPACK self-efficacy perceptions of preservice science teachers.

Percepción del profesorado de ciencias de educación primaria en formación acerca de las etapas y acciones necesarias para realizar una indagación escolar

En este trabajo se examinan las respuestas de 35 maestros de Primaria en formación a una actividad dirigida al reconocimiento de las etapas de una indagación científica y de las acciones necesarias para afrontarlas. Para ello, se diseña un ejemplo de indagación en el que se describe el proceso de resolución seguido para explicar la diferencia de precio de tres marcas de jamón. Los resultados muestran que el desempeño en la identificación de las etapas es más adecuado que en la de las acciones. Mientras que el número mínimo de participantes que identifica una etapa es de 16, hay acciones, como la recogida de datos, que solo es identificada por uno. Una implicación derivada de este estudio es la necesidad de reflexionar, durante la formación inicial del profesorado, sobre cómo se genera y evoluciona el conocimiento científico.

Investigating Perceptions of Pre-service Science Teachers towards Laboratories by Using Phenomenological Pattern

Abstract scientific concepts are made clear thanks to laboratory practices and skills related to scientific thought are developed. In this regard, laboratories distinguish themselves from classes, which are the most special areas of educational environments, with both their materials and differences in use and management. The research objective is to detect perceptions of pre-service science teachers, who have been receiving education in the Department of Science Education in the Faculty of Education, on laboratory environments used by pre-service science teachers. This research consists of three laboratory environments used by pre-service science teachers in courses of General Physics Laboratory, General Chemistry Laboratory and General Biology Laboratory within the context of Science Education training program in the Faculty of Education. Pre-service science teachers were asked to express their opinions on laboratory in a cause and effect relationship by describing them via metaphor within the context of this study. It was detected at the end of research that pre-service science teachers define their perceptions on laboratory by using various metaphors. In this respect, perceptions of pre-service science teachers on General Physics Laboratory can be interpreted as that science can be measured and absolute outcome is achieved; their perceptions on General Chemistry Laboratory can be interpreted as that science is experimental, practical and synthesis; their perceptions on General Biology Laboratory can be interpreted as that science is real life.
