The object of this study is to determine the conceptual understanding that prospective Science teachers have relating "de Broglie: Matter waves" and to investigate the effect of the instruction performed, on the conceptual understanding. This study was performed at a state university located in the western part of Turkey, with the Faculty of Education-Science Teaching students (2nd year / 48 individual) in the academic year of 2010-2011. The study was planned as a single group pretest-posttest design. A two-step question was used in the study, prior to and after the instruction. Lessons were conducted using the 7E learning model in the instruction process. When all these results are evaluated, it can be said that the conceptual understanding of the prospective teachers regarding "de Broglie; matter waves" has been taken place. In general, when all the sections are examined, it has been observed that the prospective teachers have more alternative concepts prior to the instruction and more scientific concepts after the instruction.  In this process, besides instruction, the prospective teachers have not taken any place in a different application regarding the basic concepts of quantum physics. Therefore, it has been determined that the 7E learning model used in the research and the activities included in the 7E learning model are effective in conceptual understanding.

The aim of this study is to determine the problem solving skills and science process skills of six year-old children who attended kindergarten and whether or not there is a difference in problem solving skills and science process skills of children receiving and not receiving the education with GEMS program. In the study using the experimental model with pre-test, post-test and control group, the sample group consisted of a total of 25 children including 11 children in experimental group and 14 children in control group who attended the preschool education. The “GEMS Program” was applied throughout a school year after applying pre-test to the children in the experimental group. In the scope of the study, “General Information Form” to obtain the data about the children and their families, “Parental Evaluation Form” including the evaluation of the parents about their children, “Problem Solving Scale in Science Education (PSSSE)” to determine the problem solving skills of the children and “Science Processes Observation Form (SPOF)” to measure the science process skills of the children were used. According to the results of the study, while a statistically significant difference was observed between the Problem Solving Scale in Science Education mean scores of the children in the experimental group who participated in the GEMS Education Program and of the children in control group, no statistically significant difference was observed between the mean scores obtained by the children in the experimental group from Science Processes Observation Form and the mean scores of the children in the control group.

The aim of this research is to evaluate the constructivist learning environments of physical education and sport teacher candidates. For this purpose, 928 students (523 male, 405 female) selected by the appropriate sampling method from the Physical Education and Sport Teaching Department of 17 universities consisted the sample of the research. In the study; "Constructivist Learning Environments Evaluation Scale" developed by Arkun and Askar (2010) was used in order to reveal the opinions of the students about the constructivist learning environment. The scale consists of 7 Likert type, 6 sub dimensions and 28 items. The Cronbach alpha reliability coefficient for this study was found to be .93. The lowest score that can be taken from the scale is 28 and the highest score is 196. Kruskal Wallis Variance Analysis and Mann Whitney U test were used because the obtained data did not show normal distribution (Kolmogorov-Smirnov), and the significance level was taken as 0.05. As a result of the research, the constructivist learning environments of 17th universities 3rd and 4th grade teacher candidates were evaluated in terms of age, gender and grade variables. According to this, there was no significant difference when the average scores of constructivist learning environments were compared in terms of age and class levels of physical education and sports teacher candidates. In comparison with gender, female teacher candidates were found to have a more constructive learning environment.

The purpose of this study was to investigate the meanings assigned by pre-service teachers to the wastepaper basket and waste (crumpled) papers in their drawings of a scientist. The study was carried out with 220 pre-service teachers during the 2015-2016 academic years. A phenomenological research method was used. First, the pre-service teachers were administered the ‘Draw-A-Scientist Test’ in order to identify their images of a scientist and then they were asked to describe and explain the scientist they drew. And a semi-structured interview was performed with the 34 pre-service teachers who included a wastepaper basket and waste paper in their drawings in order to identify the meanings assigned to the wastepaper and wastepaper basket by these teachers. The data were analysed by using content analysis. The results of the analysis showed that with these figures the pre-service teachers revealed their belief that when scientists conduct research, they follow a confirmatory experimental process in a similar manner to the way school science experiments. Based on these results, it can be suggested in the analysis of the drawings that waste paper and wastepaper baskets can be regarded as indicators of the stereotypical image of scientists and of the scientific method they use.

The inorganic chemistry is one of the essential courses in the education of pre-service chemistry teachers. This study investigates the differences between the adopted learning approaches and achievements of Turkish pre-service chemistry teachers' who received the inorganic chemistry course from the same lecturer. The purposes of this study are to explore the relationship between the inorganic chemistry achievements and the adopted learning approaches of pre-service chemistry teachers and to examine the effect of their learning approaches on their inorganic chemistry achievements. This study was conducted with 127 pre-service chemistry teachers from the Department of Chemistry Education at one of the public university in Turkey. “The Study Process Questionnaire” and “The Inorganic Chemistry Achievement Exams” were used as the data collection tools. The descriptive statistics and chi-square test were used for the data analysis. The results of the study displayed that (1) there is a significant relationship between the pre-service chemistry teachers’ inorganic chemistry achievement and their learning approach; (2) their learning approach has 34 % effect on their inorganic chemistry achievements according to Somers'd value.

This study aims to analyse opinions of social studies prospective teachers towards out-of-school learning. It was conducted with 12 prospective teachers who were at their final year at Kafkas University Education Faculty, Social Studies Teaching Department. In this qualitative study, phenomenological design was adopted, and the data was collected with semi-structured interview form which was developed by the researcher. To explain qualitative data and to find relationships, explanatory and inferential codes during analysis were adopted. Based on the results obtained from this study, prospective teachers expressed that they had inadequate knowledge about out-of-school learning, and out-of-school learning may present advantageous to learning process such as learning with doing-experiencing, permanence of subjects, and materialisation of information. Additionally, regarding out-of-school learning, prospective teachers expressed that there may be problems with time and incorrect learning practices. Recommendations were presented for these results.

This study was designed as a case study. Participants were 12 senior pre-service science teachers (PSTs), who took theoretical and practical courses about STEM education and socio-scientific issues (SSIs) during their education at a state university. For the study, in the first 4 weeks, theoretical courses on SSIs and STEM education were carried out. Afterwards, PSTs were asked to choose a SSI and configure this issue as a problem statement to perform a STEM activity. Participants were given a total of 3 weeks to determine the issue and prepare the STEM activity, and the researchers of the study gave systematic feedback during this period. Then, starting from the fifth week of the study, groups started to implement their STEM activities in the class, where their peers were assigned as their students. The activity plans they prepare, the field notes taken by the researchers during the implementation of the activities and the semi-structured interviews about the opinions of the PSTs on the use of SSI in STEM education were the data sources of the study. Findings revealed that PSTs found establishing STEM problem situations over SSIs suitable since they provide features such as conformity to real life, having multiple criteria and providing compatibility with other disciplines. Moreover, after their practices, they pointed out that the activities enabled both the teaching of the SSI and the integrated teaching to be carried out. As a conclusion, it is recommended to use socio-scientific problem situations to perform STEM education.

Recent science education standards emphasize the importance of the instruction of nature of science (NOS) concepts at all levels of schooling from pre-K to K-12. Delivering a proper NOS education to students is excessively dependent on their teachers with an adequate understanding of NOS concepts. The present study investigated the science conceptions of preschool and elementary teacher candidates. The data collected from a total of 506 prospective teachers were analyzed with respect to the following demographic variables: majors, genders, grade levels, high schools and GPAs of teacher candidates. “Student Understanding of Science and Scientific Inquiry (SUSSI)” developed originally by Liang et al. (2008) was the instrument used to collect data in this study. The data analyses were conducted using MANOVA and Pearson Correlation Coefficient. The corresponding mean scores of the teacher candidates in specific aspects of NOS ranged from “poor” to “informed” conceptions of science. All but one of the demographic variables yielded statistically insignificant results on the NOS conceptions of teacher candidates. The majors of the teacher candidates were detected as a significant variable influencing the conceptions of the teacher candidates. The results of the study were discussed in reference with the relevant literature.

In this research, After I have realized some technological applications in the course of general physics laboratory II of the science teacher program, this research aims to examine the effects of the students' attitudes towards technology and the information of the communication technology (ICT) with the mixed method. For this application, after the introduction of Arduino was done, it was used as a measuring instrument in the laboratory; it also used the Fritzing program for circuit diagrams and the e-support system for sending poster studies. The research was carried out with the 50 first-year students of the department of science education at Kocaeli University. In this study, the attitude scales toward technology and ICT were used to collect the quantitative data, and a semi-structured interview form was used to collect the qualitative data. For the quantitative analyses in the study, “t-Test for Dependent Groups” and “A Two-Way ANOVA was used for Complex Measurements”, for the qualitative analyses, “Descriptive Analysis” was used. The two analyses were combined according to the mixed method research model and interpreted. The results of the research showed that technological applications in the physics of the laboratory such as using arduino, fritzing program, and poster studies have a significant effect on the attitudes of students in the study group toward technology and ICT, and it was supported by the qualitative research.

The purpose of this research is to evaluate the effectiveness of the activities, which are prepared by teaching techniques that support scientific creativity, on the scientific creativity levels of prospective pre-school teachers. In the research, combined design is used, which is one of the mixed research approaches. The study group of the research included a total of 46 prospective pre-school teachers who have studied in the Education Faculty of Kafkas University in 2016-2017 academic year. The applications were carried out in the "science education" which is one of the third-grade 5th-semester courses of the pre-primary education program. The application process was completed in 4 hours a week for a total of 40 hours. In the analysis of the quantitative data collected by Scientific Creativity Test, percentage calculation and t-test were used. Explanatory and inferential codes were used in the analysis of qualitative data obtained from the in-class observations. As a result of the research, it was seen that the course activities in which different techniques were used positively influenced the scientific creativity levels of the prospective teachers. Prospective teachers' level of skills involved in creative trait, creative process, and creative product sub-dimensions also developed. It has been suggested in the direction of these results that different techniques should be used together to develop scientific creativity.

Teacher education programs are often accused of failing to prepare preservice teachers for real life classroom situations. In the case of research on classroom management, the focal point is often classroom teachers and their educational and behavioral goals rather than students’ experiences. This study aims to explore the perspectives of preservice teachers on their attitudes and behaviors in the university classrooms. For this purpose, 40 preservice teachers, who studied in the Early Childhood Education department at a state university in Turkey, were selected. The interview was chosen as the data collection method. The interview questions were based on the questions that Cothran, Kulinna and Garrahy (2003) used in their study with the secondary physical education students. The collected data were analyzed by the constant comparison method (Glaser & Strauss, 1967) and common themes were constructed through the analytic induction method (LeCompte & Preissle, 1993). In this study, the findings indicated that incompatible behaviors served different functions in teacher education classrooms. The preservice teachers perceived punitive teacher responses to students’ negative behaviors as compelling, ineffective and mostly humiliating practices. The preservice teachers provided three main elements that affect their attitudes, behaviors and experiences in a teacher education classroom. These elements were related to students, teachers, and the context of the classroom. The preservice teachers perceived their positive or negative behaviors mostly as reactions to the behavior of the teacher and the classroom environment.

Currently, it is taken for granted that teachers have to take into account the conceptions in order to achieve some efficient learning, the latter are generally resistant and may hinder the learning. Studies have shown that learning amounts to make conceptions evolve which play a determining role in the appropriation of scientific concepts such as neurotransmission, which is the subject of our study. This concept is present in the Life Science syllabus as early as high school. The aim of this study is to assess the impact of an interactive approach on the evolution of students' conceptions of neurotransmission. For this purpose, a questionnaire was administered to the first two years’ students (second year) in the Life Sciences stream at Dhar El Mahraz Faculty of Science in Fez during the academic year 2016-2017. This questionnaire was in the form of a pre-test and a post-test on learning/teaching of neurotransmission. The results of the study showed that the approach which was adopted had a positive effect on the evolution of the students' conceptions of neurotransmission in that it apparently contributed to a conceptual change for them.

The aim of this study is to present pre-service biology teachers with reading texts about the research of Van Helmont and Joseph Priestley relate to the subject of photosynthesis, for their familiarization with the processual and contextual aspects of science and their understanding of the nature of science, and to reveal the extent to which these texts contribute to the teacher candidates. The study was carried out by “action research method”.  The sample consisted of 66 biology pre-service teachers studying at Karadeniz Technical University between the years of 2016 to 2018. In this study, two separate reading texts were prepared in order to increase pre-service teachers’ processual and contextual understanding, and after the teacher candidates had read the texts, they were asked to answer the related questions. Percentage and frequency values were determined by grouping the answers as “correct, partially correct, incorrect and unanswered”. The fact that in this study, only 47% of the pre-service teachers were able to form a correct hypothesis means that their skills in this regard are in need of development. Candidates experienced some difficulty in interpreting statements that were not given explicitly in the text. The candidates' level of critical thinking is at a good level. It has been determined that they have post-modern view as epistemological belief. There is a need for designing instructional materials covering conceptual, processual, contextual dimensions of science in different subjects at university level and presenting them to biology teachers in book format.

The industrial revolution era 4.0 has now become a major topic in every country. Various sectors respond quickly to this problem, including education. In response to this, there are several aspects of skills that students must master. One of them is problem-solving skills. One of the aspects that influence the students’ problem-solving skills is the context and problem-based learning model. The purpose of this study is to describe the effect of the model on students' skills to solve physics problems. The research method used is a quasi-experimental research design with non-equivalent control group design. The data analysis technique used Independent Sample T-Test by PASW 18 with a significance 5%. Based on the results of the Independent Sample T-Test can be concluded that there is an effect on the model that was applied with a significant gain of 0,00. The results showed that the context and problem-based learning (C-PBL) model affected the physics problem-solving skills. The C-PBL model is able to improve the students’ physics problem-solving skills, communication skills, the students’ confidence in learning, as well as improving students’ understanding of physics lessons conceptually.

The empowerment of metacognitive skills has an important role in increasing the capacity of critical thinking and active control of students' cognitive processes in learning. Metacognitive skills can be enhanced through the implementation of learning strategies involving higher-order thinking. The RQA, ADI, RQA integrated with ADI are constructivistic learning strategies that can accommodate these skills. The researches specifically examining the correlation between metacognitive skills and critical thinking skills at the implementation of RQA, ADI, and RQA integrated with ADI learning strategies are still rarely found. This research is a correlational research, aiming at revealing the correlation between metacognitive skills and critical thinking skills. The data of metacognitive skills and critical thinking skills are collected by using a valid and reliable essay test. The samples of this research are the fourth semester (IV) biology education students programming Animal Physiology course in the 2016/2017 academic year consisting of 109 students. The results of this research show that (1) there was a significant correlation between metacognitive skills and critical thinking skills at the implementation of the four learning strategies, (2) the regression equations analyzed using Anova obtain regression lines (not coincide), and non parallel regression lines (intersected); meaning that there is a difference in the increase rate and magnitude of the critical thinking skills influenced by the four learning strategies. It is expected that the teachers and the lecturers always strive to improve the quality of the learning process through the implementation of active and constructive learning strategies.
