ABSTRACT
With increasing global requirements for the use of technological tools and resources in K-12 settings, there is a need to examine the technological pedagogical content knowledge (TPACK) levels of mathematics teachers because technology use in class may enhance students’ engagement and motivation in learning mathematics. Hence, the purpose of this study was to develop and validate a TPACK scale to be used in investigating mathematics teachers’ knowledge levels in TPACK components, and investigate if mathematics teachers’ TPACK levels differed in terms of gender, teaching experience and level of school. This study is based on survey research design. Data were collected from 202 mathematics teachers in the spring semester of 2016-2017 academic year. MANOVA was used for data analysis. As a result of exploratory and confirmatory factor analysis, the TPACK instrument was developed as a valid and reliable 39-item 5-point Likert scale consisting of six scales: 1. Technological Knowledge, 2. Pedagogical Knowledge, 3. Content Knowledge, 4. Technological Content Knowledge, 5. Pedagogical Content Knowledge and 6. TPACK. The results also revealed that there were significant differences between gender and technological knowledge domain in favor of male teachers. However, it was found that teaching experience and level of school had no significant effect on TPACK domains.

ABSTRACT
This study aims to develop a reliable and valid scale to identify the levels of media users’ media literacy skills. The scale development process was carried out in nine steps as recommended in the literature. Before the scale was administered, the items were reviewed by field experts and language experts and a pilot study was carried out. Responses from 322 pre-service teachers, selected via purposeful sampling, were included in the analysis. Item discrimination was tested via item-total correlation and it indicated that none of the items were below .30. In the confirmatory factor analysis, it was found out that the scale and the theoretical model showed a fit between good and acceptable. Convergent validity, divergent validity and 27% upper-lower group means were also examined. As for the internal consistency, Cronbach’s alpha value of the scale was calculated as .919 and alpha values of the factors were calculated as .768, .833, .720 and .838 respectively. The results revealed that Media Literacy Skills Scale, which consists of 45 items gathered under the four main factors of ‘access, analyze, evaluate and communicate’, is a reliable and valid measurement instrument. This up-to-date scale covers all main skills of media literacy and it consists of a sufficient number of questions to obtain rich data and ensure measurement precision. In addition, it covers new media as well as mass media and this

ABSTRACT
The use of emerging technologies shape learners’ knowledge creation and transformation processes. In this regard, this study aimed to develop a scale to investigate 8th graders’ competencies regarding the educational technology standards based on ISTE-NETS. After a review of relevant literature, an item pool was prepared. The pool was improved through expert opinions and pilot implementations. The items were administered to 620 Turkish students from six different cities for the exploratory factor analysis (EFA). A four-factor structure with a total of 21 items emerged and explained 51 percent of the total variance. Factors were named technical proficiency, creativity, digital citizenship and participation, and innovativeness. Each factor had acceptable internal consistency coefficients. For the confirmatory factor analysis (CFA), the scale was administered to 210 new participants from a different city in Turkey. A few modification indices led to acceptable fit values. Thus, the suggested factor structure was considered plausible. Implications of the study were provided, followed by the recommendations for further research.

ABSTRACT
The present study aimed at developing a scale for diagnosing instructional strategies to be used to determine the instructional strategies applied in the instructional process. In the process of the scale development, first the related literature was reviewed. Following this, field experts were asked for their views, and the instructional activities to be carried out in the instructional process were identified. Afterwards, considering the similar and different features of the instructional activities, they were grouped by associating them with instructional strategies. The draft scale, which made up of a total of 291 items in the beginning, was exposed to a four-phase application process prior to the actual application. At the end of this process, it was transformed into a 70-item scale applied to 614 home teachers and field teachers. For the content validity of the scale, field experts were asked for their views. Data collected were analyzed with the methods of principle components analysis and exploratory factor analysis. As a result of the exploratory factor analysis conducted to determine the construct validity of the scale, the factor load of each item in the scale was found over .30. In order to determine the factors involving the items in the scale, the orthogonal rotation was applied with the Varimax technique to the data collected. The scale included two sub-scales. The rate of the factors in the sub-scale of meeting the total variance was 43% for the sub-scale of focus strategies and 62% for the sub-scale of process strategies. The value obtained by testing the internal consistency for the whole scale was found as α=.964. With respect to the item-whole scale correlational consistency, the items in the scale ranged between.406 and .816. The findings obtained in the process of developing this five-point Likert-type scale demonstrated that the scale could be used successfully in determining the nature of instructional strategies applied in the instructional process.

ABSTRACT
The purpose of this study was to develop a scale which could be used to evaluate instructional website designs from the perspective of visual perception theories. For this purpose, a scale of 50 items was developed based on the literature and expert opinions. Visual perception theories such as Gestalt Theory, Brunswick’s Probabilistic Functionalism, Neuropsychological Theory, Theory of Direct Perception and Ecological Optics, Constructivist Visual Perception Theory and Computational Approach to Visual Perception provided a basis for the development of scale items; also a focus group discussion was employed. 196 students from the Computer Education and Instructional Technologies (CEIT) Department filled the scale. The exploratory factor analysis (EFA) was applied along with the principal component method on data. Following the factor analysis, a single factor scale was developed. The loading of each item in the scale was found to be over .30. The internal consistency coefficient of the overall scale was high (α=.961). The corrected item-total correlation coefficient of the items was .301 and over. Through factor analysis, it was revealed that the scale had a single-factor structure with an explained variance of 35%. At the end of the study, several recommendations were presented for future studies.
