plant conception preschool and primary school pupils mental model drawings...
Children from southern and northern Brazil have a basic knowledge of plants, which they observe during their everyday life. Children ages between 3 to 10 years old (kindergarten & primary school), but the majority of them in the age group of 4-5 (total 145) were asked to draw what they think is a plant (total sample=332). Afterwards, a equal number of boys and girls randomly chosen were interviewed individually (mix ability) to list plants they said they knew and where they had seen them. Then they were asked to give exemplars of the local plants which they had seen. These data from the exploratory study show that pupils are in touch with their environment and recognize plants that are part of it. The everyday experiences of these children in school and out of school, at home and in leisure activities with family and friends, contribute to their knowledge about plants and such knowledge is complemented in the preschool and primary school classes by appropriate teaching. Educational implications of these findings are discussed.

The purpose of the research is to evaluate pre-service preschool teachers' knowledge about environment by analyzing their drawings about it. 70 first grade, 99 second grade, 56 third grade and 44 fourth grade, with a total of 269 students have been evaluated in this research. This qualitative research was made with social structuralism vision. The data used in this research were gathered by draw and tell conversation technique, where pre-service teachers were asked to draw the first thing when they think about environment and explain it. When analyzing the data, both qualitative and quantitative techniques were used. After analyzing collected data, it is seen that most used object in drawings are tree, human, house and sun, respectively. 4 themes and 12 sub-categories under these themes are detected by pre-service teachers' drawings. The most drawn theme by pre-service teachers is Theme 3: a place which affected/designed by third persons, while the least drawn is Theme 4: a place where humans, animals and plants lives together. 10 categories have seen after analyzing explanations of the drawing. Most explanation seen in the places that supports human life category. Independent variables of the research (sex and grade level) and themes and explanations of the drawings are statically and meaningfully related to each other. The most significant result of this research is that pre-service preschool teachers have human-centric system of thought about environment.

instructional readers’ theatre technique history teaching reading skill...
In this article, a teaching strategy which not only blends yesterday and today in a meaningful way but also powerfully integrates literacy and history will be examined. Firstly Readers’ Theatre as a technique will be introduced. Secondly, the usage guidelines of Readers’ Theatre will be presented. Finally the opinions of secondary school students about Readers’ Theatre as an instructional component in history teaching will be discussed. The research was conducted on 72 11th grade students from Deneme Secondary School in Çankaya district in Ankara in the spring term of 2013-2014 school years. For the purpose of the study, students were taught by using Readers’ Theatre technique in history lessons for four weeks and at the end of this implementation, the semi-structured interviews were held to determine the opinions of students about Readers’ Theatre technique. The themes were formed by making content analyze to the collected data. It is concluded that the students mainly have described Readers’ Theatre as “theatre”. They have found Readers’ Theatre useful in many respects as they outline the positive effect of the technique on their reading and obtaining historical information. They like most the cooperation with their peers and acting. The vast majority of students have not mentioned any dislikes and a few of them have difficulties to follow the script. Finally, the answers of the majority of the students on the implementation of Readers’ Theatre again are “positive” and their suggestions for better implementation are “on stage”, “the same way” and “using visuals”.

Advanced Science Students’ Understandings on Nature of Science in Finland
nature of science scientific literacy advanced students epistemological thinking...
Majority of NOS studies comprise of determination or assessment studies conducted with ordinary students. In order to gain further understanding on variation in NOS understandings among the students, there should be different research attempts focusing on unconventional students such as academically advanced students. The purpose of this study is to determine epistemological understanding of Finnish academically advanced science students concerning aspects of NOS. The study was a case study (N=39) conducted with qualitative perspective. Questionnaires on the students’ attitude toward science and motivation toward science learning plus a form for the teacher’s ideas and VNOS-C, were used as diagnostic tools and data collection instruments. The study revealed that the majority of the students were found to be naïve in aspects such as “empirical basis of science”, “observation and inference”, “subjectivity of scientists”, “social and cultural embeddedness”, “creativity in science”, “theories and laws” and “tentativeness”.

A Reflection on Distorted Views of Science and Technology in Science Textbooks as Obstacles to the Improvement of Students’ Scientific Literacy
scientific literacy knowing about science science inquiry technology society environment textbooks conceptions...
Scientific literacy has been increasingly considered a major goal of science education. While textbooks remain the most widespread tools for pursuing this goal within classrooms, they have been slow to adapt to the most recent epistemological paradigms, often still conveying distorted views of science and technology. Accordingly, we present herein a theoretical framework specifically intended to highlight the potential of textbooks to promote students’ scientific literacy. It is additionally argued that, often, the misconceptions conveyed by textbooks represent obstacles to the acquisition of a fair image of science and, therefore, to the acquisition of scientific literacy. Finally, a textbook analysis is suggested.

Influence of Gender and Knowledge on Secondary School Students’ Scientific Creativity Skills in Nakuru District, Kenya
influence gender knowledge scientific creativity...
The purpose of this study was to investigate the influence of gender and knowledge on scientific creativity among form three biology students (third year in secondary school cycle) in Nakuru district in Kenya. The cross- sectional survey research was employed. A sample of eight schools with a total of 363 students was selected from the population using stratified sampling technique. Two instruments, namely, Biology Achievement Test (BAT) and Biology Scientific Creativity Test (BSCT) were used to collect data. The psychological definitions of creativity tested are sensitivity, recognition, flexibility and planning. The mapping of these psychological definitions of creativity onto scientific meanings is explained using the model that guided construction of items in BSCT. Data analysis was done using quantitative methods. The findings of this study indicate that the form three biology students who participated in the study had a low level of scientific creativity. Secondly, the level of scientific creativity is knowledge and gender dependent. The findings may help teachers and other stake holders in education in inculcating creativity skills amongst science students.

Scientific Creativity: The Missing Ingredient in Slovenian Science Education
creativity education elementary education secondary education innovation strategies...
Creativity is regarded as one of the cornerstones for economic and social progress in every society. There are two possible ways to get creative people to work for an enterprise or community. The first is by attracting creative employees by good working conditions – a solution for those who can afford such an approach. For communities that are not so rich, the only solution is to foster creativity by education and by helping small and medium enterprises to create products based on creative ideas and innovations. In Slovenia, proposals for nourishing creativity and innovations emerge from the government thus forgetting that creativity does not start at University or on the first day of employment. To increase creativity, immediate action should be taken throughout the educational system, recognizing that society needs not only creative artists but scientists, economists and engineers as well. Through the analysis of the legislation, syllabi and textbooks, it can be recognized that they do not promote or even allow creativity in science education; even more, they can be regarded as creativity killers. In such a way key documents and teaching resources are placing creative science teachers in the position of guerrillas in a battle against prevailing teaching methods influenced by highstakes external exams or measurable outcomes. To improve science creativity, the legislation should be changed to give creativity appropriate value, and teachers must be educated to use methods that increase creativity in students, with the aim of producing open minds that will be able to work in a creative way.

self-efficacy history education pedagogical formation program pre-service teachers...
The purpose of the present study is to investigate pre-service history teachers’ perceived self-efficacy and the effect of pedagogical formation training on this perception. The study is based on a one-group pretest-posttest research design, which is a type of pre-experimental design. For the purpose of the study, in the first week of the formation training, the “Teachers’ Sense of Efficacy Scale” developed by Tschannen-Moran and Hoy and adapted to Turkish by Capa, Cakiroglu and Sarikaya was administered as a pre-test to a group of 178 pre-service history teachers who underwent pedagogical formation training in 2016-2017 academic year in two different universities in Turkey. The same scale was administered again as a post-test at the end of the 28-week training. The study has found out that the pedagogical formation training did not make a significant difference in pre-service history teachers’ perceived self-efficacy except for the classroom management subscale, in which the self-efficacy scores of pre-service history teachers decreased after the pedagogical formation training.

The purpose of this study was to investigate the effect of lessons conducted in out-of-school learning settings on 5th graders science achievement within the scope of a guidance material that was prepared to be used in out-of-school learning settings in accordance with the “Let’s Solve the Riddle of Our Body” chapter objectives. The pretest / posttest equalized control group design, which is one of the quasi-experimental designs, was used in this study. The sample of this study was composed of a total of 31 5th grade students (15 were in experimental group, 16 were in control group) that were selected from secondary schools in the first semester of the 2015-2016 academic year in Tokat Province. Let’s Solve the Riddle of Our Body Chapter Achievement Test (LeSROBAT) was administered before and after the implementation of the guidance material to measure the students’ achievements and retention. The lessons were conducted as suggested by the current curriculum in the control group. The data were analyzed using independent samples t-test and covariance analysis (ANCOVA). As a result of the analyses, it was found that the LeSROBAT post-test scores of experimental group were significantly higher than the control group. Within this context, it was concluded that the out-of-school learning settings positively contributed to academic achievement and the guidance material that was developed within the scope of this study was effective. The results of retention test analyses didn’t reveal any significant difference between the posttest and retention test scores of experimental and control groups. When the LeSROBAT retention test scores were examined, it was observed that the scores of experimental group was higher than the control group.
Teacher-Students´ Interaction in Comparison of Teacher´s Self-perception and Students´ Point of View
interaction of teacher and students questionnaire on teacher interaction slovak students teacher of biology...
Building a teacher-student relationship is important for creating trust, mutual understanding and respect. The interaction of teacher and students can be found using the 48-item Questionnaire on Teacher Interaction. The result is the Model for Interpersonal Teacher Behavior, consisting of four dimensions, which are further divided into eight sectors to evaluate the teacher. The main goal of our study was to show how the teacher and students perceive the environment of the class, whether their views match, and whether it is a statistical significant dependence among different sectors of the model teacher-students interaction. The sample size consisted of 63 Slovak students of 12th grade and their teacher of biology. Our results have shown that the teacher has evaluated herself similarly to the students, but without a statistical significant difference. In monitoring of the relationship of scales in the whole group of respondents, in the group of male and female respondents we showed statistically significant differences between the sectors. Using of Questionnaire on Teacher Interaction can help mutual knowing of students and teachers and the creation of positive relationships.
Defining the Relationship between the Perceptions and the Misconceptions about Photosynthesis Topic of the Preservice Science Teachers
perception photosynthesis misconception preservice science teachers...
The aim of the research is to determine the perceptions of the preservice science teachers about the photosynthesis and to reveal the relation between these perceptions and the misconceptions of the existing concepts. In the research, field scanning method was used as a descriptive research method. The sample of the research is composed of 355 preservice science teachers trained in different universities. For the selection of the sample, purposeful sample selection was used and attention was paid to the fact that the preservice science teachers had taken the General Biology-I and General Biology-II courses at the undergraduate level in the determination of the class level to be included in the study. The "Photosynthesis Concept Achievement Test" (PCAT) developed by the researcher and composed of 4 questions was used as a data collection tool. Quantitative data obtained from the study were analyzed using SPSS.20 package program while content analysis was performed in the analysis of qualitative data. As a result of the research, it was determined that the preservice science teachers' perceptions of photosynthesis were in the direction of chemical and biological approaches and that the teacher candidates preferred the chemical approach rather than the biological approach. However, preservice science teachers who prefer the chemical approach have reached the conclusion that they are in much more misconception than the biologically approaching teacher candidates.
The Effects of Biology Laboratory Practices Supported with Self-regulated Learning Strategies on Students' Self-directed Learning Readiness and Their Attitudes towards Science Experiments
biology laboratory self-regulated learning strategies self-directed learning readiness attitude...
Self-regulation is an active and constructive process in which students regulate and observe their own behaviour, motivations and cognition by setting their own goals during their learning process. In this study, the aim is to investigate the effects of biology laboratory practices that are supported by self-regulated learning strategies on students’ readiness for self-directed learning and their attitudes towards science experiments in laboratory settings. This study, which was undertaken as a quasi-experimental study in accordance with the pretest-posttest design with a control group, was implemented. Second year students who studied science teaching in the faculty of education at a state university in Konya in the academic year of 2018-2019 made up the sample of this study. There were two groups in the study which were “The Control Group” and “The Experimental Group”. In order to measure the students’ self-directed learning readiness levels, “Scale of Self-Directed Learning Readiness in Laboratory” was used and to measure attitudes towards science experiments “Scale of Attitudes towards Science Experiments” was utilized. Both scales were implemented as pre-tests before the study and as post-tests after the completion of the implementation process. The analysis of the data was conducted via SPSS 18. Independent samples t test was conducted to understand whether biology laboratory practices supported with self-regulated learning strategies have any effect on students’ readiness for self-directed learning and their attitudes towards science experiments in laboratories. According to the findings of the study, biology laboratory practices supported with self-regulated learning strategies were observed to make a significant difference in favour of the experimental group considering their self-directed learning readiness and their attitudes towards science experiments.

This study aims to evaluate the academic outcomes of the flipped classroom approach in the teaching of students who are deaf or hard of hearing (DHH). Furthermore, it aims to activate the role of the teacher through encouraging both teachers and students to engage in active learning styles, while acknowledging individual differences. Participants consisted of 12 female undergraduates with hearing disabilities in a 251 CI course (applications of ICT in teaching and learning) at the College of Education, King Saud University. The study was applied throughout a semester on the contents of the course. The content material and pre-class assigned work (e.g. instructional videos and tasks) were delivered through Blackboard (learning management system), while active learning activities were carried out in class. Using mixed methods, students’ perceptions of their new learning environment were explored through a post-term questionnaire distributed at the end of the semester, in addition to writing a reflective report. Furthermore, participants were requested to write a reflective journal at the end of each lecture. Results indicated the effectiveness of the flipped classroom strategy for students. Moreover, the data indicate a positive impact on students' content learning and improved skills (e.g. collaboration and interaction). The content material which was developed for the specific course (251 CI) could be utilized for the remaining students enrolled in this course. The researcher recommends using the flipped classroom teaching strategy for courses in higher education, as the methodology can be extended and implemented through following a similar framework applied in this study.
Evaluation of Pre-service Science Teachers’ Argumentation Skills, Knowledge Levels and Attitudes Regarding Organ Transplantation and Donation
pre-service teacher attitude argumentation skill knowledge level organ transplantation organ donation...
The purpose of this study was to evaluate pre-service science teachers’ argumentation skills, attitudes and knowledge levels regarding organ transplantation and donation (OTD). Teachers play a fundamental role in providing information to children/adolescents and could influence their attitudes. Organ transplantation is a life-saving hope for many people, but shortage of organs for transplantation is a universal problem. Having a positive attitude and true knowledge are essential for teachers that affect students’ future attitude toward this topic. The research method was descriptive and cross-sectional. The sample of research was 472 pre-service science teachers, who were sampled by using convenient sampling method and are students of Science Education Department at four different public universities. Data collection instruments were developed by researchers as valid and reliable questionnaire in order to determine the attitudes, knowledge levels and argumentation skills of pre-service teachers regarding OTD. Results observed that the pre-service science teachers' argumentation skills in a socio-scientific subject such as OTD were at a very low level, their attitudes were at a moderate level, and their knowledge level was above the average. Results of the study have shown that graduated high school type and grade level have played important roles in the positive attitudes, high argumentation skills and high knowledge level about organ donation. No significant difference was found in the attitudes and knowledge level of pre-service science teachers toward OTD in terms of gender. The gender only affected the ability of argumentation.
The Impact of an Interactive Approach on the Evolution of Moroccan University Students’ Conceptions of Neurotransmission
initial conceptions neurotransmission interactive approach conceptual change evolution...
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.
Understanding the Processual and Contextual Aspects of Science by Means of the History of Photosynthesis
history of science photosynthesis aspects of science...
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.

environmental learning higher order thinking skills hots-aep students...
Environmental learning in the 21st century requires students to have Higher Order Thinking Skills (HOTS). The purpose of this study was to measure HOTS students using Higher Order Thinking Skills Assessment based on Environmental Problem (HOTS-AEP). The research method used in this study was descriptive method with a total sample of 248 students consisting of Elementary School (ES), Junior High School (JHS), Bachelor Program (BP), and Master Program (MP). The results showed that students overall have a very low HOTS category. HOTS scores scale of 0-100 on ES (22.3) are still higher than JHS (20.2). Whereas at the university level, BP scores (19.9) are lower than MP (21.4). This showed that learning must be oriented towards increasing HOTS through various media development learning, learning materials, learning models, and strategies. This study concludes that the HOTS score of students was still very low and needs to be improved.

The study aims to promote relevant and effective environmental education (EE) through extracurricular clubs. For this, we studied the state of play of environmental activities (EA) carried out by 48 environmental clubs belonging to urban and rural areas of the Regional Academy of Education Fez-Meknes, Morocco. These extracurricular environmental clubs remain so far without formal environmental education programs. In this study, we identified the bulk of programs offered by extracurricular environment clubs, including types of scheduled activities and percentages of achievement and student beneficiaries in urban and rural settings. In addition, we have identified the main barriers to achieving certain environmental activities. The significant correlations detected between some of the variables studied allowed us to better explain the achievements and the weaknesses of these clubs. Finally, we have made recommendations to promote relevant and effective extracurricular environmental education.
