The aim of this study was to investigate the effects of activity based learning on sixth grade students' mathematics achievement in comparison to traditional learning, and determine their attitudes towards activities. Experimental research design with pretestposttest control group was applied in the study. The participants, which included 78 sixth grade students, were previously divided into two groups by random assignment. One group received traditional learning and the other group received activity based learning. The study was carried out for four weeks on the mathematics subject of "integers". For collecting data the mathematics success test and the Likert type attitudes towards mathematics activities scale were used as pretest and posttest. As a result, the academic achievement for both groups were positive increased. On the other hand, while the attitudes towards activities of students' in the experiment group decreased significantly, they increased in the control group.

The purpose of this study is to examine the sub-dimensions of approach towards research of college students, according to the variables of gender, class, taking a scientific research class or not, and studying in an associate or undergraduate program. The sample of this study is composed of 250 associate degree and 403 undergraduate degree students which have been selected with a suitable sampling method for this study which was carried out with universal screening method. A suitable sampling method has been selected for the easily reachable and applicable individuals being available, as for the constraints of time, money and manpower. The reason of including these students into the research group is the inclusion of a scientific research methods class in their curriculum. As the data collection tool, approach scale towards research which was developed by Çelik, Gazioğlu and Pesen (2012) was selected. For the analysis of the data, independent sampling t-test, oneway variance analysis, normality and Levene test were applied. According to the results obtained from the study, a significant difference was found in the sub-dimensions of interest, importance and motivation which are part of the sub-dimension of approach towards research as a subject of the study, for gender difference. However there has been no significant difference in subdimensions of usefulness and anxiety. Also, no significant difference was detected for the sub-dimensions of interest, importance and motivation when compared for the class variable and the variable of having a scientific research class or not. When compared for the associate/undergraduate degrees, there has been a significant difference for the sub-dimensions of the study which are importance, motivation and anxiety, however, no significant difference has been found for sub-dimensions of interest and usefulness. Considering the approach of the college students towards research, we might say that additional optional classes could be added into the curriculum, together with the research methods class.

The aim of the study was to determine the impact of project-based learning on academic achievements of vocational school of higher education students and to investigate their views on the topic. In the study, a mixed descriptive design where qualitative and quantitative data were both collected and analyzed. The quantitative part was conducted with relational screening method and the qualitative part was conducted with descriptive analysis method. The study group included 13 freshmen students attending the vocational school of higher education, building inspection program in a university located in Eastern Anatolia region in Turkey during the 2016-2017 academic year spring semester and selected with convenience sampling method. The study was conducted during the 14 weeks long period where the related programming course was instructed. In the study, quantitative data were collected with an achievement test that measured the academic achievements of the students in AutoCAD programming course. The qualitative data were collected with a structured interview form designed to collect the student views on the related course. Quantitative data were analyzed with the t-test and the descriptive analysis method was used to analyze the qualitative data. In conclusion, it was determined that project-based learning had a positive impact on academic achievement. Furthermore, students expressed that they achieved meaningful learning as a result of the project-based learning application and the method was adequate for the instruction process, improved their interest in the course and related the content with daily life.

The aim of this study is to investigate the attitudes of prospective mathematics teachers towards mobile learning based on different variables and examine their opinions on this subject. This study used an exploratory design, which is a mixed design involving the analysis of qualitative and quantitative data collected together. The participants, which consisted of 181 prospective teachers, were selected by convenient sampling. The study was performed with a mixed method in which both qualitative and quantitative data were collected and analyzed together. The quantitative data of this study were collected by a mobile learning attitude scale, while the qualitative data were collected via a structured interview form. Independent samples t-test was used to analyze the quantitative data, while content analysis was used on the qualitative data. As a result of the study, it was found that the attitudes of the prospective teachers towards mobile learning were on a medium-level both in the general total and sub-factor (freedom, advantages, practicality and limitations) scores, and the attitudes of the male participants were higher than those of the female participants. On the other hand, it was found that the prospective mathematics teachers had positive views on mobile learning, most stated that this type of learning has advantages and disadvantages and it may be used in extracurricular environments and increases course success, but it is not economical.
