The Effect of Mathematics Instruction through Computer Algebra Systems on the Academic Achievements of Secondary Education Students: Turkey Example
The purpose of this study is to determine the effect of the mathematics teaching, which is carried out by mathematics teachers through computer algebra systems, on the achievement of students. A hundred and forty five 10th grade students have taken part in the study as participants. In the research where quantitative research methods were used, quasi-experimental design was used. In the study, class implementations were carried out by three mathematics teachers who had in-service training about the integration of the computer algebra systems to the learning-teaching environments beforehand. In the implementations at issue, teachers carried out computer-assisted instructions about parabola through Mathematical software in experimental groups. In control groups, they carried out the lessons by using information and communication technologies at a baseline level using traditional teaching method. In the research, students' mathematics report grades and also parabola achievement tests, which were used as the pretest and the posttest, were used as data collection tool. The data obtained from the research were analyzed through Mann-Whitney U and Wilcoxon signed ranks tests. Besides, the effect size of the obtained data was calculated. As a result of the research, it was seen that the achievement of the experimental group, whose lessons were carried out with computer algebra systems by providing technology integration at transformation level, are higher than the achievement of the control group, whose lessons were carried out with the traditional teaching method by providing technology integration at replacement level. Besides, as the calculated effects size is considered, it is understood that computer algebra systems have a strong effect in the occurrence of the differences between the two groups
Teaching Probability to Pre-Service Teachers with Argumentation Based Science Learning Approach
The aim of this study is to explore the effects of the argumentation based science learning (ABSL) approach on the teaching probability to pre-service teachers. The sample of the study included 41 students studying at the Department of Elementary School Mathematics Education in a public university during the 2014-2015 academic years. The study is a quasi-experimental study. The experimental group consisted of 20 students, and the control group consisted of 21 pre-service teachers. While the teaching probability argumentation based science learning approach was applied to the teacher candidates in the experimental group, traditional methods were applied to the control group. As a data collection tool, the Probability Achievement Test with 15 open-ended questions, which was prepared by the researcher himself, was used. As a result of the application, statistical significant differences were found between the probability successes of the experimental group and control group in favor of the experimental group.

HIGH SCHOOL MATHEMATICS TEACHERS’ VIEWS ON COMPUTER-ASSISTED MATHEMATICS INSTRUCTION THROUGH COMPUTER ALGEBRA SYSTEMS IN TURKEY
In this paper, high school mathematics teachers’ views on computer-assisted mathematics instruction and on computer algebra systems (CAS) were explored in two stages, before and after they were trained on it. This study is based on the case study model of the qualitative research method. Semi-structured interview forms constitute the data of the study. Some codes and themes were established with the descriptive and content analyses of the data. The results show that teachers had positive opinions about computer-assisted mathematics instruction before they were trained, yet a majority of them was not able to use it in their classes for several reasons. However, it is seen that none of the teachers except for one knew about computer algebra systems (CAS). It is understood after the training that all the teachers wanted to use computer-assisted mathematics instruction in their classes, and thus they needed to use Mathematica, which is a computer algebra system, during the process. Likewise, while most of the teachers did not want their students to interact with computers or tablets in their classes before the computer-assisted mathematics instruction training, almost all of them had a favorable opinion of it after the training.

Transfer of Mathematical Knowledge: Series
The aim of this study is to explain students’ ability to transfer their knowledge about mathematical series to the problems that they encounter. The data of the study were obtained by using two different tests, namely “Problem Solving Test (PST)” and “Series Character Identification Test (SCT)” which were developed by the researchers. The study was conducted to third- grade students from department of elementary school mathematics education in the 2009-2010 academic year. In view of the analysis of the data, it was observed that the students experienced no difficulty in the SCT which required procedural knowledge. They experienced difficulty in the PST which required skill to transfer their knowledge about the series to the circumstances that they encounter. According to these results, it was determined that the students experienced difficulty in transforming real life problems to series and interpreting these problems
