Reliability is a characteristic of scores, not tests or measurement instruments. One of the methods to estimate the reliability of the scores on a test or measurement instrument is Cronbach’s coefficient alpha method. In other words, Cronbach’s alpha is an estimate of the score reliability based on the internal consistency among the [item] scores. In addition to this, Cronbach’s coefficient alpha should not be interpreted as a measure of the test’s or the measurement instrument’s unidimensionality or taken as an index of the homogeneity of a measurement instrument. Briefly, Cronbach’s alpha is not a measure of unidimensionality or homogeneity.

The purpose of this study is to determine whether the knowledge structure of first level elementary school students for the ''light'' concept can be explained by "knowledge-as-theory perspective" or "knowledge-in-pieces perspective" and to contribute to the development of new teaching and learning techniques. In this research, clinical interview method was used. This method is a qualitative research method which aims to reveal what lies coginively behind the individual's explanations. In this study 21 fifth-grade students were selected and interviewed as participants. Students with similar level of success and Socio-ecomomic status, were choosen. A dark room was prepared in the same school where experimental activities were held and a set of clinical interviews were arranged. It was concluded that the knowledge structures about light concepts of students are suitable for "knowledge-in-pieces perspective" in theoretical concepts and "knowledge-as-theory perspective" for descriptive concepts.

In this study,it was aimed to evaluate the attitudes of elementary mathematics teacher candidates against the profession of teaching in terms of different variables. “Attitude Scale related to the Teaching” and “Personal Information Form”, which are developed by Erkuş, Şanlı, Bağlı ve Güven (2000, 27-33) as a data collection tool and author in order to collect information about students, respectively, have been used in this study in which used the scanning method. Cronbach’s alpha reliability coefficient of scale is 0.99. The data of this study have been obtained by applying “Attitude Scale related to the Teaching” to the total of 158 students who attend to the first, second, third and fourth classes of the department of elementary mathematics teaching of Education Faculty of Muş Alparslan University in spring semester of 2013 year. The data obtained with attitude scale have been analyzed in SPSS17.0 package program. The independent sample t-test and one-way variance analysis techniques have been used in the analyzing of data. At the result of study, it has never been detected a significance differences in the students’ attitudes towards teaching profession in term of some variables such as “gender”, “class level”, parents’ education level and “the kind of graduated high school”. Also, another important result obtained from this study is that of the students’ attitudes towards teaching profession is appropriate level and being positive.

The purpose of this study is to evaluate the feelings and thoughts of students about a web-based, circle-approach to learning about the subject of motion in Physics lessons. Study was carried out on 25 students by qualitative research method in the fall semester of 2009-2010 academic year at 85. Yıl Milli Egemenlik Anatolian High School which is located within the centrum of Diyarbakır. As a means of collecting data, interview forms with open ended questions were used which were depeloped by the researchers so that students could express their opinions about Web Based Learning Circle. According to the research results, in general, all the activities used during the lesson and teaching-learning environment were found useful by the students however, most of the students refered to the university entrance exams as “the exam which determines the rest of our lives” students stated that to prepare for this exam, having Phsysics lessons with Web-based, Learning Circle Approach was not helpful for them. In the light of the findings obtained, suggestions have been made.
