distributed leadership distributed leadership scale validity and reliability...
The purpose of this study was to adapt “Distributed Leadership Scale” originally developed by Davis into Turkish Language. A total of 386 participants including teachers employed in high schools in Tokat participated in the study. Explanatory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were performed to test the structural validity of the scale. EFA results illustrated that adapted scale consisted of seven factors. In the light of the original scale form, these factors were named as “School Organization”, “School Vision”, “School Culture”, “Instructional Program”, “Artifacts”, “Teacher Leadership”, “Principal Leadership”. The scale consisted of 34 items and reliability coefficients for the subscales from .75 and .92. Results finally revealed that Distributed Leadership Scale-Turkish Adapted Form is a valid and reliable measurement tool to be used in describing the distributed leadership behaviors in schools.

Concepts of Plants Held by Young Brazilian Children: An Exploratory Study
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.

Learning Mathematics in English at Basic Schools in Ghana: A Benefit or Hindrance?
mathematics proficiency english language student culture language of learning and teaching...
Facilitating effective mathematics learning and higher mathematics achievement have long been recognized as a key to the scientific and technological advancement of the African continent. While the central role that language proficiency plays in mathematics teaching and learning has received an overwhelming research attention in the literature over the past two decades, this is not the case among African policy-makers and political leaders. Drawing mainly from our professional experiences as mathematics educators and from the international research literature, our primary intent in this paper is to answer this question: How does the learning of mathematics in English at the basic school level help or hinder students’ mathematical proficiency? To answer this question, the paper is organized as follows. The first part, the introduction, gives a brief overview of the language of learning and teaching in Africa. The second part describes the method and conceptual framework undergirding the research. In the third section, we have analyzed the effects of mathematics learning and teaching through English for basic students whose mother tongue is a Ghanaian language. The conclusion offers four recommendations for developing and improving the mathematics proficiency of students in basic schools.

Farm Education and The Effect of a Farm Visit on Children’s Conception of Agriculture
agriculture farm visit media conception intervention drawings interviews...
Personal connections to agriculture have decreased considerably in Finland during the last few decades due to struc-tural changes in agriculture. In this study, we will elucidate the understanding and conception of agriculture amongst urban pupils who have grown up during the 21st century. The research strategy consists of intervention in form of a farm visit, with pre- and post-assessment. The methods for collecting data were drawings for gaining a diversified un-derstanding of how pupils understand, experience and conceptualise agriculture. The drawings were analysed by visual content analysis. In addition, interviews, analysed by inductive content analysis method, were used to clarify the re-sults. Qualities of farms as authentic learning environments are defined and studied The study revealed that many pupils had irrational conceptions of agriculture before the farm visit (38 %), but decreased significantly after the visit. One of the explaining factors for these irrational conceptions was considered to be the influence of media sources. Farms as educational learning environments were able to correct pupils’ false conceptions. A realistic image of agriculture is of significant value for becoming an aware and responsible consumer as well as choosing a career in agriculture.

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”.

The major purpose of the study was to investigate factors which contribute to the decline in students’ academic performance in junior secondary schools in Botswana since 2010. The study was mainly quantitative and used the positivist inquiry paradigm. The study employed critical theory for its theoretical framework. Questionnaires were used to gather data from two hundred participants. Some documents were analyzed to supplement the information collected through the questionnaire. Data were analysed using the computer package known as Statistical Package for the Social Sciences (SPSS) version 15. The findings of the study showed that there were several factors that can contribute toward students’ low academic performance ranging from low staff morale to students unpreparedness for the examinations. The study, therefore, recommends that high teacher’s morale, availability of resources and parental involvement are critical for the attainment of high quality education in Botswana secondary schools. Furthermore, the findings of the study have implications for research and practice.

Motivation is an inner force that activates and provides direction to our thought, feelings and actions. Two main characteristics of motivation are goal directed behavior and persistence. Motivated people persistently work for the goal until it is achieved. This paper explores the nature of motivation in the context of learning and seeks to relate it to self-efficacy, self- concept, confidence and self-esteem. Motivation is presented as a ‘second order’ variable be- ing very much dependent on attitudes as well as perceived goals, needs and value. Ways of assessing motivation are considered and the typical use of questionnaire approaches is criticized heavily. These can measure what a person perceives but the perceptions may or may not correspond to reality. Indeed, the entire mathematical basis of data handling with questionnaires is questioned. A typical questionnaire is then used with a large sample of 600 1st and 2nd year science intermediate students, drawn from the province of the Punjab in Pakistan and the data obtained examined statistically. Correlations between the responses patterns in all 30 Likert-type questions were examined using Kendall’s tau-b while Principal Components Analysis, using varimax rotation, looked at the questionnaire overall as well as sub-groups of questions. Correlation values were found to be very low, suggesting no factor structure and, indeed, the factor analysis showed that there is no factor structure with the questionnaire used with this large population. Chi-Square, as a ‘contingency test’, was applied to compare the distributions of responses, gender separated. Gender differences were found only in a minority of questions. It is argued that motivation is highly multi-variate and that no simple factor structure is to be expected. It is also argued that, with ordinal data, following no prescribed pattern of distribution, only non-parametric statistics are appropriate. The traditional approaches are statistically incorrect and, as a result, will often miss key insights.

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.

The major purpose of this study was to explore the social studies teachers’ perceptions and understandings of citizenship education in primary schools in Botswana. The study adopted a post colonial lens by using the notions of the pedagogy of imperialism and contrapuntal criticism to interrogate the teachers’ perceptions of citizenship education. The study was qualitative in nature and employed the naturalistic inquiry paradigm. Qualitative methods were used to collect data. Data were analyzed using grounded theory through the constant comparative technique. The findings of the study revealed that social studies teachers perceived teaching about Botswana as citizenship education. The paradox lies in the teachers’ view that knowledge about Botswana’s cultures, histories and politics constitutes citizenship education. Therefore, the study recommends that citizenship education be re-imagined to take into account both the local and global trends on citizenship education. Furthermore, teachers have to be cognizant of the politics of mainstream academic knowledge and work towards knowledge construction devoid of imperialist ideologies.

Pupils’ Beliefs in Cultural Interpretations of ’Heat’ associated with Anger: A Comparative Study of Ten Ethnic Communities in Kenya
science culture beliefs...
Emerging evidence indicates that culture influences pupils learning of science. However, the influence of culture on science learning is usually not considered when developing science curricular for both primary and secondary schools. This study investigated the extent to which primary and secondary school pupils believe in cultural interpretations of the physical phenomenon of ‘heat’ associated with anger and the influence of education level, ethnic communities and gender on cultural beliefs. Cross-sectional survey research design was used. The target population was Standard Seven, Form one and Form Three pupils in ten districts selected from Nyanza, Rift Valley, Central, Eastern and Coast Provinces in Kenya. The ten districts were selected purposively to represent 10 different ethnic communities from the five provinces. A total of 2837 secondary and 625 primary school pupils participated. The pupils were drawn from 15 primary and 31 secondary schools .A questionnaire was used to gather information from pupils. Both qualitative and quantitative techniques were used in analyzing data. Hypotheses were tested using the chi square ( X 2) statistic at α = 0.05 level of significance. Some of the results obtained give statistically significant relationship between pupils’ beliefs in cultural interpretations of scientific phenomenon of heat associated with anger and the communities where they come from. This implies that such beliefs are confined to specific communities studied. There appears to be no significant association between pupils’ beliefs in cultural interpretations of the scientific phenomenon of heat and level of education in some of the communities. The implication is that education reduces beliefs in cultural interpretations in such communities but does not eradicate such beliefs. There was also no statistically significant association between pupils’ beliefs in cultural interpretations of the scientific phenomenon of heat and gender, implying that both boys and girls equally believe in cultural interpretations. The findings from this study inform curriculum developers of some of the cultural beliefs that are likely to influence the learning of science. It is recommended that teachers discuss cultural interpretations of scientific concepts before introducing them in their lessons.

An Event-Related Potentials Study of Mental Rotation in Identifying Chemical Structural Formulas
chemical structural formulas event-related potentials mental rotation rotation-related negativity...
The purpose of this study was to investigate how mental rotation strategies affect the identification of chemical structural formulas. This study conducted event-related potentials (ERPs) experiments. In addition to the data collected in the ERPs, a Chemical Structure Conceptual Questionnaire and interviews were also administered for data collection. Eighteen university students majoring in chemistry were recruited. In the ERP experiments, the participants were required to identify 2D figures, 2D chemical structural formulas, 3D objects and 3D chemical structural formulas. The contours of 2D figures are similar to those of 2D chemical structural formulas, but they contain no content knowledge. Likewise, the contours of 3D objects are similar to 3D chemical structural formulas without content knowledge. The results showed that all students used similar strategies of mental rotation in identifying 2D figures, 3D objects and 3D chemical structural formulas. However, the high-achieving students used different strategies in identifying 2D figures and chemical structural formulas, while the low-achieving students tended to use similar strategies of mental rotation in identifying both 2D figures and chemical structural formulas. The results indicate that some of the difficulties in identifying 2D chemical structural formulas that students encounter are due to their inappropriate strategies of mental rotation.

lesson study techno-pedagogical competencies secondary school mathematics teachers fractal geometry...
Technological Pedagogical Content Knowledge (TPACK) is a model that explains how teachers use technology more effectively in the context of technological, pedagogical, and content knowledge. Teachers' TPACK competencies play great importance in this regard. Lesson study has also been playing significant roles in the development of teachers' professional trainings. When the researches on TPACK and lesson study have been analyzed, the research is expected to provide significant contributions to the literature. This study aims to present reflections from a lesson study practice that carried out to urge techno-pedagogical competencies of the secondary school mathematics teachers and to reveal the development of teachers’ progress. The study used case study method, and it was conducted with three in-service teachers. The research data were collected through semi-structured interviews, voice recorder, and observation notes. To analyze the collected data, descriptive analysis method was used. The results have revealed that teachers have made much more progress in designing, implementing, and problem solving in terms of TPACK competencies. It has also been determined that teachers’ development of openness to the innovations was limited. This limitation appeared to emerge as a result of teachers’ time anxiety and insufficient knowledge regarding the use of technology.

In order to reflect the integration of the teachers’ content knowledge, pedagogical knowledge, and technology usage skills to the class context and to provide the expected outputs for the program's purposes, it is needed to be revealed the different dimensions of Technological Pedagogical Content Knowledge (TPACK). In this study, it was aimed to investigate the teacher training programmes related to pre-service science teachers’ TPACK. This study was designed as a cross-sectional study. In the 2015-2016 academic year, a total of 269 pre-service teachers (73 of them from 1st grade, 73 of them from 2nd grade, 87 of them from 3rd and 36 of them from 4th grade students) attending Science Education Department participated in this study. As a data collection tool, 7 subscales of “Technological Pedagogical Content Knowledge Scale of Pre-Service Teachers”; namely, technology knowledge, pedagogical knowledge, content knowledge, technological pedagogical knowledge, technological content knowledge, pedagogical content knowledge, and technological pedagogical content knowledge were used. According to the results, as the class level of pre-service teacher increases, their level of technological pedagogical content knowledge increases as well. Moreover, there is a significant difference on behalf of pre-service teachers at the 1st grade in all dimensions of technological pedagogical content knowledge scale.

The aim of this study is to reveal the benefits gained from “Special Training Methods II” course and the problems prospective mathematics teachers encountered with it. The case study method was used in the study. The participants in the study were 34 prospective mathematics teachers studying at a Primary School Mathematics Education Department. The data collection tools were a form composed of open-ended questions and semi-structured interviews. Descriptive analysis of the quantitative data was carried out. In the “Special Teaching Methods II” course, beginning in the spring term of the 2015-2016 academic year, teaching activities on “multiple intelligences”, “discovery”, “group work”, “problem-solving”, “history of mathematics” and “computer-assisted teaching” were developed and implemented. It was concluded that these activities helped students like mathematics more, understand the importance of helping each other and cooperation and have more enjoyable lessons, as well as aiding their cognitive, social and emotional development. It was also found that through these activities participants improved their belief in themselves and increased their confidence regarding teaching mathematics. The participants also faced with some difficulties during the application process. They mostly mentioned that preparing worksheets was time-consuming, finding a school to perform the activity was hard and students were reluctant.

Effective school administrators and teachers are those who provide the least restrictive learning environments for all students. The main goal of this study was to analyze the effects of inclusive science education on the general education population of middle school students’ scientific conceptual understandings. The study was designed as a quasi-experimental model and conducted in a middle school in a large urban school district in Midwestern US. Approximately 4% of students in the school were receiving special education services. The participants in the study were selected through non-random selection. The participants of this study included 20 students without disabilities in each classroom with a total number of 120 students from a total of six different middle school classrooms. The study included two classrooms (one inclusive and one non-inclusive) for each grade level (6, 7, and 8). The conceptual change of students without disabilities was measured using the Density Assessment, which included 20 multiple choice questions. SPSS program was used for data analyses. Paired samples t-test and a multivariate group analysis test were conducted to investigate significant differences on students’ conceptual understandings. The findings showed that the effect of inclusive education was significant and positive on the conceptual understanding of students without disabilities in inclusive science classrooms.

The study investigated differences in students’ reported overall test anxiety before, during, or after test taking among two school-levels and gender. Differences among three test anxiety components (thoughts, off-task behaviors, and autonomic reactions) were also examined. Participants were 725 primary (349 females, 376 males) and 375 middle (180 females, 195 males) school students from a metropolitan city in Turkey. Turkish students’ reported overall test anxiety declined from primary to middle school, with females showing higher test anxiety throughout school years. Whereas students rated thoughts high, autonomic reactions were rated low; followed by off-task behaviors. Female and male students did not differ in thoughts and autonomic reactions. School-level differences were found in off-task behaviors and autonomic reactions. The pattern of Turkish students’ overall test anxiety derived as a combination of thoughts, off-task behaviors, and autonomic reactions was discussed, and educational implications were offered.

This study examines the subjects and concepts in biology perceived to be difficult to learn and teach by 759 pre-service biology teachers registered in the pedagogical formation program at Uludag University Faculty of Education in the academic year of 2005-2016, as well as the associations that word “biology” first calls to their mind. The study was designed as a survey model, and a questionnaire of three scaled questions was used as a data collection tool. The data were classified into 10 different categories based on different branches of biology: Anatomy-Morphology, Biotechnology, Ecology, Evolution, Physiology, Genetics, Histology, Cytology, Systematics and Reproduction and Development. Following the classification, the data were analyzed using frequency and percentages. The subjects and concepts perceived to be difficult to learn by the pre-service teachers are respectively as follows: photosynthesis and its stages, genetics, circulatory system, aerobic respiration, respiratory system, anaerobic respiration, protein synthesis, phanerogams, DNA structure and function, cryptogams, mitosis, plant systematics, endocrine system, meiosis, ETC, urinary system, plant physiology, taxonomy, evolution and digestive system. The subjects and concepts perceived to be difficult to teach by the pre-service teachers are respectively as follows: photosynthesis and its stages, protein synthesis, circulatory system, endocrine system, meiosis, plant systematics, evolution, mitosis, reproduction, genetic crossing over problems, Latinization of names, urinary system, genetics, ecology, aerobic respiration, DNA structure and function, plant tissues, glycolysis and anaerobic respiration. These findings confirm the need for developing undergraduate programs in biology and promoting the research culture at the secondary education level.
