The Development of Mathematical Knowledge for Teaching of Mathematics Teachers in Lesson Analysis Process
mathematics teacher lesson analysis mathematical knowledge for teaching...
This study aims to explore the role of lesson analysis in the development of mathematical knowledge for teaching. For this purpose, a graduate course based on lesson analysis was designed for novice mathematics teachers. Throughout the course the teachers watched videos of group-mates and discussed the issues they identified in terms of student-teacher relationship for a student centered instruction. Analysis over the video made teachers notice points and came to realize the thoughts of students; they had otherwise missed at the classroom. They achieved improvements regarding the awareness of the need to identify the cases presenting the most difficulty to the students in terms of teaching, and the necessity to take precautions regarding such points, to learn about the reason of the difficulty, and to pay attention to the statements by the students. Therefore, it is possible to note that the teachers improved themselves in terms of student’ knowledge with respect to the mathematical knowledge for teaching.

inquiry preschool science stem-education...
This study tested and integrated the effects of an inquiry-based didactic method for preschool science in a real practical classroom setting. Four preschool classrooms participated in the experiment (N = 57) and the children were 4–6 years old. In order to assess children’s attention for causal events and their understanding at the level of scientific reasoning skills, we designed a simple task in which a need for information gain was created. Compared to controls, children in the post-test showed significant learning gains in the development of the so-called control of variables strategy. Indeed, they executed more informative and less uninformative explorations during their spontaneous play. Furthermore, the importance of such programmes was discussed in the field of STEM education.

7e learning cycle science teaching meta-analysis...
This article reports the results of a meta-analysis of the effectiveness of 7E learning cycle in science teaching. Totally 35 different effect sizes from 24 experimental studies, comprising 2918 students were included in the meta-analysis. The results confirmed that 7E learning cycle have a positive effect on students’ achievement. The overall effect size (Hedges’s g) value obtained from independent studies was calculated as 1.245 (% 95 CI, SE = .148) between confidence intervals 956 and 1.534 according to the random effects model. Among all effect sizes 32 had a positive effect whereas 3 of them had negative effect. A number of sub-group analyses (school level, type of publication, subject matter and duration) were conducted. The effect of 7E was not significant for school level, type of publication and duration. However, regarding the subject matter a significant difference was observed. The high effect size calculated in this meta-analysis implies that the 7E learning cycle is a useful strategy that should be included in science curriculums.

This study provides a framework for the production of Hypermedia Instructional package. It also assessed the effectiveness of hypermedia instructional mode of delivery on students’ performance in Chemistry. This is with a view of improving the learning of Chemistry which may eventually help to improve students’ performance. The developmental study employed a pre-test, post-test control group design. The research sample consisted of 60 private secondary school students in Osun State with an enrolment of 30 students from each of the two schools selected. The students were thereafter assigned to experimental and control groups. The stimulus material used for the experimental group was the Hypermedia Instructional Package, while the Control group received instruction with similar content through the conventional method. The test instrument used was Hypermedia Learning Achievement Test (HLAT). Content and face validity of the instrument used was carried out by experts in the area of tests and measurement. The Cronbach’s alpha reliability coefficient for the HLAT gave a value of 0.72. Data collected were analyzed using descriptive and inferential statistics. Results obtained showed that students exposed to the Hypermedia Instructional Package (HIP) performed significantly better than those exposed to the conventional teaching method (t = 5.458, df = 58, p < 0.05). Results also revealed a significant difference in the retention ability of students in Chemistry between those exposed to the package and those that were not (t= 6.842, df=58, p<0.05). The study concluded that the use of HIP was an intervention which improved students’ performance retention and attitude towards Chemistry.

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.

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.

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.

Consolidation of Science Education in Ethnically Divided Postwar Bosnia and Herzegovina
consolidation science education bosnia and herzegovina...
Because of war and civil war on the territory of Bosnia and Herzegovina, education in ethnically divided country has become fragmented. Because of postwar divisions thirteen different ministries of education or similar bodies are responsible for education, resulting in inefficiency and low quality. To overcome differences, a committee of experts has prepared an outcome-based common core curriculum for science education from preschool to the upper secondary school level. Since the working group comprised representatives from all major entities, ethnic and religious groups, and school levels, as well as teachers from Biology, Chemistry, Geography and Physics, a positive outcome for the consolidation of science education can be expected.

What Do Teachers Do When They Say They Are Doing Learning Rounds? Scotland’s Experience of Instructional Rounds
instructional rounds learning rounds collaborative professional development...
This paper reports on research into the practice of learning rounds in Scotland. Learning rounds are a form of collaborative professional development for teachers based on the instructional rounds practice developed in the USA. In recent years learning rounds have gained high profile official support within education in Scotland. The research finds that what teachers in Scotland do when they say they are do-ing learning rounds varies widely from school to school and deviates significantly from the practice of instructional rounds. The implications of this for who is learning what in the practice of learning rounds is considered. The wider implications of the Scottish experience for the development of in-structional rounds practice in other countries is also considered as are the implications for promoting collaborative professional development practice more generally.

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”.

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.

This study examines the effect of project based learning on 8th grade students’ statistical literacy levels. A performance test was developed for this aim. Quasi-experimental research model was used in this article. In this context, the statistics were taught with traditional method in the control group and it was taught using project based learning in the intervention group. Statistics was given for four weeks according to pro ject based learning at intervention group. The performance test was applied to total 70 students as pre and post-test. Participants are from two different classes of a middle school in Trabzon. The data were analysed using Rasch measurement techniques. This measurement allowed both students’ performance and item difficulties to be measured using the same metric and placed on the same scale. All raw scores converted linear score in order to obtain equal interval scale. Acquired linear scores were compared. In the analysis of gained datum covariance analysis are used. According to gained results in pre-processing application there isn’t substantial difference between the achievements of intervention group and control group; but after processing between the achievements of intervention group and control group there is a substantial difference statistically in favor of intervention group. The results of the study revealed that the project based learning increased students’ statistical literacy levels in the intervention group.

statistical literacy attitude project based learning statistics education...
This study investigates the effect of the project based learning approach on 8th students’ attitude towards statistics. With this aim, an attitude scale towards statistics was developed. Quasi experimental research model was used in this study. Following this model in the control group the traditional method was applied to teach statistics wheras in the intervention group project based learning approach was followed. The attitude scale towards statistics was applied as pre-test and post-tests to 70 students studying at two different 8th grade classes of a middle school in Trabzon during the 2011–2012 Academic Year. The results of the study revealed that the project based learning increased students’ attitude towards statistics in the intervention group. Therefore, the use of project based learning approach during statistics course in mathematics classes is recommended.

Measuring Teaching Best Practice in the Induction Years: Development and Validation of an Item-Level Assessment
teacher induction development assessment rasch modeling teaching internship teacher attrition...
Schools and teacher induction programs around the world routinely assess teaching best practice to inform accreditation, tenure/promotion, and professional development decisions. Routine assessment is also necessary to ensure that teachers entering the profession get the assistance they need to develop and succeed. We introduce the Item-Level Assessment of Teaching practice (I-LAST) as a flexible framework-based approach for quantitative evaluation of teaching best practice in the induction stages. We based the I-LAST on a novel framework for teaching best practice, and used Fuller’s scale as a framework for understanding the potential of the I-LAST in providing longitudinal measures for growth. Using the context of a year-long teacher induction program in the Midwestern United States, we collected data through an online survey from 46 teaching supervisors who were asked to evaluate their interns. We used the Rasch partial credit model as a criterion for construct validity, and measured dimensionality and reliability from both Rasch and classical frameworks. The I-LAST was found to be a unidimensional, valid, and reliable measure for teaching best practice. It demonstrated the ability to provide reliable scores for specific sub-dimensions of best practice, including those which manifest at various stages along Fuller’s scale. Potential uses of the I-LAST to advance understanding of the role of teacher induction programs in fostering productive growth in new teachers is discussed.

Effect of Web Assisted Education Supported by Six Thinking Hats on Students’ Academic Achievement in Science and Technology Classes
six thinking hats technique web-assisted education achievement attitude...
Advances in computer technologies and adoption of related methods and techniques in education have developed parallel to each other. This study focuses on the need to utilize more than one teaching method and technique in education rather than focusing on a single teaching method. By using the pre-test post-test and control group semi-experimental researchmodel, this study examined the effects of the web-assisted education method supported by six thinking hats technique on student achievement, on students’ attitudes towards science and their attitudes towards the use of computers in science classes. The working group of the study was composed of 7th graders in a state secondary school in the 2013-2014 academic year. A working group consists of two randomly selected classes assigned as the experimental and control groups. The working group comprised of 50 students with 25 experimental and 25 control group students. Paired samples t-test, independent samples t-test and ANOVA techniques were used in analyzing the data collected via data collection tools to compare the experimental and control groups. The results showed that web-assisted education materials prepared with the use of the six thinking hats technique increased student attitudes towards science and computers. Students’ attitudes towards computers were similar based on the variables of owning a computer and gender. Paternal education levels had no significant effects on student attitudes towards computers and their academic achievement.

The study investigated the perception of teachers of agriculture about Supervised Agricultural Experience Programmes (SAEP) in secondary schools in Ekiti and Ondo States. The population used for the study consisted of 520 teachers of agricultural science in all the secondary schools in Ekiti and Ondo States. The sample used for this study was 136 teachers of agricultural science drawn through a proportionate stratified sampling technique to pick four(4) teachers from each of the 34 Local Government of the two states. The Instrument used was a structured questionnaire to investigate the extend to which the teachers agreed on disagree with statemenst regarding SAEP. The questionnaire were test and re-tested yielding a reliability co-efficient of 89. (Cronbach alpha). The data for the study were analyzed using mean, standard deviation t-test and two tailed probability statistics. The probability level was set at P<0.05. Thirty eight items were generated for the study. The study found out among others that the teaching of agriculture needs improvement; that though SEAP related contents are in the agricultural science curriculum the teaching and learning of agriculture are not vocationally oriented in Ekiti and Ondo States. It was recommended among others that agricultural programmes in all schools should include supervised agricultural experience programmes, while the State School Boards in collaboration with relevant Ministries should conduct informational workshop and orientation on SAEP for educational planners, administrator and teachers of agriculture in Nigeria.

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.
