Uyan, Umut
Knowledge sharing has become the critical success factor for effective knowledge management since it bridges the gap between knowledge creation and utilisation. So far, socio-psychological factors have yet to attract the attention of scholars despite numerous barriers impeding the flow of knowledge. The current study is, therefore, designed to develop a self-reporting measurement instrument that uncovers hidden sharing barriers triggered by negative outcome expectations. To test the psychometric properties of the newly designed instrument, a stepwise procedure was applied. The findings indicate that the instrument aimed at developing is a multidimensional construct consisting of 13 items and four dimensions (assumption of being ignored, assumption of not meeting expectations, assumption of being non-sense and assumption of conflict avoidance). The results of this study provide preliminary evidence for the reliability and validity of the 13-item negative outcome expectation scales as a measure of hidden assumptions towards knowledge sharing.

Ilhan, Aziz; Tutak, Tayfun
The aim of this study is to develop a valid and reliable measurement tool that measures mathematical visualization perceptions for mathematics teacher candidates. Therefore, the type of study is a survey research. Research was carried out with 462 (336 Female, 125 Male) mathematics teacher candidates from a university located in the Eastern Anatolia region Turkey in 2018-2019 spring season. Exploratory and confirmatory factor analyzes were performed for the analysis of research data. In the process of development of Mathematical Visualization Perception Scale (MVPS); the preparation of the pool of material, testing of the validity of the scope and appearance, conducting the trial application, ensuring the construction validity, calculating the reliability and establishing the final scale were followed. As a result of the exploratory factor analysis, a valid and reliable 5-point Likert-type scale consisting of 42 items, with 6 factors [Additional Drawing (AD), Spatial Thinking (ST), Direction Concept (DC), Relation with Daily Life (RDL), Transition from Algebra to Geometry (TAG) and Transition from Geometry to Algebra (TGA)] was created. Cronbach Alpha internal stability coefficient of these factors was calculated as 0.938. The factor structure of the scale was also confirmed by confirmatory factor analysis. As a result of the findings obtained, it was suggested to the researchers who will study in the related field to evaluate mathematical visualization perceptions of mathematics teacher candidates by using related scale with different sample groups or different variables.
