In addition, how different moderator variables affect reliability coefficients was examined. A number of criteria have been set to determine the studies to be included in meta-analysis. Of 95 Cronbach’s Alpha coefficients obtained from 92 studies that were selected according to criteria were included in the meta-analysis. In the data analysis, reliability generalization based on meta-analysis was used. The effect of moderator variables on variability in reliability estimations as effect size was examined by Analog ANOVA. As a result of the research, it was found that the mean alpha was .81 for overall studies; .76 for the short form and .87 for the long form of OHS. In addition, it was concluded that number of items had a statistically significant effect on the reliability estimation in terms of heterogeneity of t...

The study group consists of 624 biology, physics and chemistry teachers working in secondary schools in Antalya, Denizli, Burdur and Ankara. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were conducted in order to determine its structural validity. Cronbach-alpha and stratified-alpha coefficient values were calculated for the reliability of the sub-dimensions and the whole of the scale, respectively. In EFA, Kaiser-Meyer-Olkin (KMO) value was found to be 0.92 and the Bartlett Test result (912 91 = 6519.27, p <.00) was found significant. In addition, in original scale, a two-factor structure was found. This two factors solution explains 59.192% of the total variance. In CFA, factor structure of the scale was tested for two-factor solution as it was designed. According to the findings, it was found that the scale, containing ...

The aim of this study is to determine awareness, exposure, and knowledge levels of science (physics, chemistry and biology) teachers about nanoscience and nanotechnology. Teachers (N=624) from secondary schools in Turkey comprised the working group. Descriptive methods were used in data analyses. Awareness and exposure subscales were adopted from the Nanotechnology Awareness Instrument developed by Dyehouse et al. (2008), and the knowledge subscale, developed by the authors, was added to the Turkish version. Differences among or between the teachers’ awareness, exposure, and knowledge levels regarding nanoscience and nanotechnology were determined. No significant differences were found in levels of awareness, exposure, and knowledge of teachers in terms of subject specialisation and educational levels; however, some significant differences were found in gender, tenure, grade and type of school, in-service t...

Blended instruction has been created using a combination of face-to-face instruction with web-based learning management system. This is a descriptive study. This study was conducted on students of Mathematics-I course at a military vocational college. Courses have been conducted in the classroom setting and MS Power Point presentations, lecture notes, and quizzes were presented to the students via the intranet. Optional online quizzes based unit with multiplechoice question item pool was provided for the benefit of students. In the end of the semester Online Quiz Evaluation Form was applied to students to determine their opinions on online quizzes. 103 students have filled out the form. Data was analyzed using frequency, mean and ttest. In general it has been found that students are undecided about online quizzes. According to findings of this study, stu...

The two main views concerning appropriate level to teach nanoscience and nanotechnology (NSNT): The first favors teaching in higher education; the second recommends familiarizing and teaching in all grade levels. Aim of this study is to determine the opinions about NSNT education and to propose NSNT education for biology curriculum using the current status. A teacher interview form was used for data collection and applied to 121 biology teachers. Data collected via questionnaires were analyzed through quantitative descriptive analysis. Biology teachers’ opinions of NSNT education focused on definition, awareness, importance and developments, benefits, applications, risks and ethical issues. Participants presented view of integrating nanotechnology topics into the curriculum and expected a positive impact on students’ career pr...

In addition, it was concluded that number of items had a statistically significant effect on the reliability estimation in terms of heterogeneity of true effect sizes, and sample type had a statistically significant effect on the reliability estimation for OHS (long-form). But sample type had no effect on the reliability estimation for OHS-S (short-form), and field of study had no effect for both short and long form reliability estimates.

Harmanlanmış öğretim, yüz yüze öğretim ile web tabanlı öğrenme yönetim sisteminin birlikte kullanılmasıyla oluşturulmuştur. Betimsel yöntem desenindeki çalışma bir meslek yüksekokulunda Matematik-I dersini alan 204 öğrenci üzerinde gerçekleştirilmiştir. Dersler sınıf ortamında yürütülmüş ve intranet üzerinden öğrencilere powerpoint (ppt) sunuları, ders notları ve quizler sunulmuştur. Çevrimiçi quizler ile ünite bazlı toplam 126 maddelik çoktan seçmeli test maddesi havuzundan öğrencilerin yararlanmaları sağlanmıştır. Dönem sonunda öğrencilerin çevrimiçi quizler hakkındaki görüşlerini belirlemek amacıyla Çevrimiçi Quiz Değerlendirme Formu kullanılmıştır. Hazırlanan form, 103 öğrenci tarafından cevaplanmıştır. Verilerin analizinde frekans, ortalama ve t testi kullanılmıştır. Öğrencilerin genel olarak çevrimiçi quiz konusunda kararsız kaldıkları belirlenmiştir. Bilgisayar sahibi olan öğrencilerin bilgisayar sahibi olmayanlara göre, evinde internet bağlantısı olan öğrencilerin evinde internet bağlantısı olmayan öğrencilere göre ve daha önce web tabanlı sınav deneyimi olan öğrencilerin, web tabanlı sınav konusunda herhangi bir deneyimi olmayan öğrencilere göre çevrimiçi quizler konusunda daha olumlu oldukları bulunmuştur. Çevrimiçi quiz uygulamasının soru bankasının oluşturulmasının özellikle Matematik dersi için oldukça zaman alıcı olduğu belirlenmiştir. Uygulamanın en önemli avantajları öğrenci quizlerini okumak için gereken zamanın azalması ve kaynakların etkin kullanılmasıdır.
