The aim of this study is to examine the effect on the success of the students “Bisector and Median correspond at a point in a triangle” findings stated within Geometry course curriculum by using computer assisted teaching program Dynamic Geometer’s Sketchpad. During this study quasi experimental design was used on preliminary and posttest groups. This research was conducted on twenty five 10th grade students studying Computer Information Systems (CIS) at Technical and Vocational High School. “A Success Test” consisting of 12 questions which had been previously formed through the observations of specialized teachers was used as preliminary and posttests. Each group was chosen without any meaningful difference between preliminary test results gathered. Two groups were formed due to preliminary test results: an experiment group T-10 class (13 students) and a control group A-10A (12 students). It was targeted to access findings developed by Dynamic Geometer’s Sketchpad programmed in the experiment group but the control group wasn’t intervened. An independent sample t-test on pair comparison was used among different groups paired samples t-test was used on pair comparison among same groups. Findings achieved during the study revealed that Dynamic Geometer’s Sketchpad was more effective on students’ success than traditional teaching methods. A meaningful difference on behalf of the experiment group was determined within the independent sample t-test conducted on final test results. [t(23)=3.176, p< .05]. These findings indicate that Dynamic Geometer’s Sketchpad software used in the experiment group is more effective on students’ success compared to traditional teaching methods used in control group.

The purpose of this study is to compare the effectiveness of using a dynamic software or tools (compass, straightedge) for geometric drawings in lines and angles on the achievement of pre-service mathematics teachers and to bring out the opinions of pre-service mathematics teachers on using compass-straightedge or a dynamic software for teaching geometry. The data in this study which conducted with 55 pre-service teachers, 24 for the first experimental group and 31 for the second experimental group, has been gathered by focused group interviews and achievement test. Based on the analysis of the study data, there is not a significant difference determined on the achievement level of the group 1 teachers who use a dynamic software and the group 2 teachers who use compass-straightedge. In addition, it is determined that using compass-straightedge or a dynamic software has positive impact on pre-service teachers’ achievement. The vast majority of the group 1 teachers have supported the use of a dynamic software in terms of “effective in complicated drawing”, “saving of time” and “comprehending terms more effectively. The vast majority of the group 2 teachers have supported the use of compass-straightedge in terms of “making drawing easier”, “retention in learning” and “having more fun”.

This study aims to investigate the effect of blended learning on students’ achievement for the topic of quadratic equation in mathematics education. The sample of the study consists from 34 student of tenth class of Oğuzeli Multi Programming High School of Gaziantep city at the 2012-2013 Education and training term. 10 questioned exam were used for pre-test and 10 questioned another test were used for post-test as data collecting tool. Arithmetic average, independent-samples t-test and paired-samples t-test were used to analyze the data. The findings of this study showed that there is a significant increase in students' achievement scores in instructional applications of the face to face learning approach. Likely there is also a significant increase in students' achievement scores in instructional applications of the blended learning approach. However there is not any statistically significant difference in achievement scores of students between the face to face and blended learning groups.

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.
