The Effect of Critical Thinking Disposition on Entrepreneurship Levels: A Study on Future Teachers

AbstractThe aim of this research is to study the relations between Critical Thinking Dispositions and entrepreneurship levels of future teachers and to evaluate them in terms of some demographic variables. Relational scanning model weree used in this study. The California Critical Thinking Disposition Inventory (CCTDI) developed by Facione, Facione &Giancarlo (1998) and adapted to Turkish by Kökdemir (2003), Entrepreneurship Scale (ES) developed by Yılmaz & Sünbül (2009) were used as the data collection tool. The sample of this study is formed by 548 pre-services from Science, elementary school, mathematics, social studies Education, Department of Faculty of Education. In order to analyze the data, ANOVA, independent group t-test, Pearson correlation coefficient analysis, regression analysis were used. Between scales has been found a positive correlation. It has been seen that critical thinking dispositions have a significant effect on entrepreneurship levels. There are statistically significant differences on gender, high school and department variables in terms of CCTDI. Also, statistically significant differences were determined on grades in terms of ES

Instructional curriculum based on cooperative learning related to the structure of matter and its properties: Learning achievement, motivation and attitude

In this study we aimed to analyse the effects of the Instructional Curriculum based on Cooperative Learning (ICBCL) prepared for the subjects, the orders of electrons and chemical properties, chemical bonds, compounds and their formulas, and mixtures on 7th grade learners’ learning achievements, motivations to learn science, and their attitudes towards learning science. Pre- and post-test quasi experimental design was used in this study in which the participants, 89 7th grade learners were attending a public secondary school in Istanbul, Turkey during the 2013–2014 academic year. The Diagnostic Test for the Structure of Matter and its Properties (DTSMP), developed by the researchers, the Motivation Scale to Learning Science (MSTLS), developed by Dede and Yaman (2008), and the Attitude Scale Towards Science Lesson (ASTSL), developed by Biçer (2011) were used as data collection instruments. SPSS 16 and Lertap 5 were used for data analysis. As a result of the post-tests, learners from the experimental group achieved significantly higher mean scores than learners from the control group. This reflected that ICBCL was highly effective on increasing learners’ achievement levels by preventing possible misconceptions, developing motivation, and positive attitudes compared to the current Science Teaching Curriculum (STC).Keywords: attitudes towards science; cooperative learning; instructional curriculum; motivation to learn science; science educatio

Investigation of the Relationship between Study Approaches and Self-regulated Learning Skills of Teacher Candidates

AbstractThis study aims the investigating the relationship between study process and their self-regulated learning skills of teacher candidates. This research is designed as relational scanning model. In the study, 2 scales are used as tool of data collection: Self-regulating Learning skills (SRLS) Scale, developed by Turan (2009), Study Process Questionnaire (SPQ) revised by Biggs, Kember & Leung (2001), adapted in Turkish by Yılmaz & Orhan (2011a). 272 Teacher candidates from Turkish, Science, social studies, elementary school, mathematics, psychological counseling-guidance education forms the sample of the study. In order to analyze the data, SPSS 16.00, ANOVA, independent t-test, Pearson correlation coefficient techniques are used. At the end of the study, between SRLS scale with profound approach factor of SPQ has a positive relation and with superficial approach factor of SPQ has a negative relation. The significant differences weren’t found between the graduated secondary schools with scales; but according to gender and to the department, significant differences were found between SRLS scale with superficial approach factor of SPQ

The Investigation of Pre-service Science Teachers’ Opinions on Some of the Biology and Biotechnology Concepts

Today, it is seen rapid progress in some areas such as biotechnology. Since determination of the DNA structure, advances in biology, biotechnology and genetic engineering have emerged very fast and on such a great scale that teachers should be able to adapt to new developments. Teacher education has an important task to prepare students for their coming professions. The objective of this study was to find out pre-service science teachers’ conceptions on biology, biotechnology, genetically modified (GM) food and their ideas on teaching and assessment strategies to help their students’ understanding of these technologies. The participants were 150 pre-service science teacher in Turkey. A questionnaire contains eight closed-ended and four open-ended items were used to determine pre-service science teachers’ perceptions of biology and biotechnology issues. Quantitative and qualitative methodologies were used to analyze data. As a result of this research, it was observed that pre-service science teachers does not have sufficient knowledge or their information that is contradictory. DOI: 10.5901/jesr.2016.v6n1p

Determination of the epistemological and ontological beliefs of secondary school students: Determination of the epistemological and ontological beliefs

The purpose of this study is to determine the epistemological and ontological beliefs of secondary school students concerning some demographic variables. Relational screening model was used in the study. Epistemological Opinion Scale and Ontological Opinion Scale developed by Ünal-Çoban and Ergin (2008; 2010) were used as the data collection tools. SPSS 21.0 program was used to analyze the data. The sample of this study is formed with students enrolled at the 6th, 7th and 8th grades in state secondary schools in Turkey. As a result; it was observed in this study that the epistemological and ontological beliefs of students are at moderate levels. Epistemological and ontological beliefs have been found to be effective in some variables

Study on Optimum Extraction Conditions for Olive Leaf Extracts Rich in Polyphenol and Flavonoid

Ultrasound-assisted extraction (UAE) of polyphenols and flavonoids from olive leaves was investigated. The effects of temperature (27?37°C), solvent concentration (10?70% ethanol (EtOH), v/v) and time (30?60 min) were determined by both experimental and Response Surface Methodology (RSM) techniques. Free radical scavenging activity for the antioxidant capacity was tested by 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical. For total phenolic content (TPC), 43.8252 mg-GAE/g dried leaf was predicted at the optimum conditions (34.18°C, 43.61% (v/v) of EtOH, and 59.99 min). In case of total flavonoid content (TFC), 31.9920 mg-CE/g dried leaf was calculated at the optimum conditions (34.44°C, 70% (v/v) of EtOH, and 60 min). © , Copyright © Taylor & Francis Group, LLC
