    Students' success in English vocabulary acquisition through multimedia annotations sent via whatsapp
    (Anadolu Universitesi, 2019) Cetinkaya, Levent; Sutcu, Selim Soner
    The purpose of this study is to determine the effects of the multimedia annotations which were sent through instant messaging application WhatsApp on students' success in English vocabulary acquisition together with their opinions on the educational use of WhatsApp and the multimedia annotations. In the study, mixed method model, which combines both quantitative and qualitative data, was employed. Results of the variance analysis of the quatitative data indicated that the multimedia annotations sent through WhatsApp yielded a meaningful increase in students' vocabulary acquisition. Multiple comparison test to identify the reason of this increase revealed that 'Text+Picture+Audio' and 'Text+Picture' multimedia annotations increased students' vocabulary acquisition meaningfully when compared to other learning multimedia annotations. Although 'Text+Audio' multimedia annotation contributed to the success of students more than the students who received only 'texts', it wasn't found meaningful. In the qualitative aspect of the study, students expressed their willingness to go on the treatment. They stated that similar researches in their other courses could be useful. They also added that they could learn unconsciously and expressed positive opinions towards the use of the pictures and audio annotations in particular. However, a few students reacted negatively againts the irrelevant posts and stated that the posts occupied a lot of space on their phones. © Anadolu Universitesi.

    (Turkish Education Assoc, 2019) Cetinkaya, Levent
    The purpose of this study is to determine the effects of problem based mathematics teaching through mobile based applications which are used as assistive technology. It has been designed in a mixed method model that integrates research results. The participants of the experimental group were chosen from the students who continue to take mathematics courses within the traditional curriculum and were included in the process of problem based learning via mobile applications. Quantitative dimension of the study was designed using quasi-experimental design with pretest-posttest control group and it was seen that the success of the students in two different environments showed significant difference before and after the experiment. In other words, it has been found that the common effects of successive measurement factors on the success of different learning environments are significant. Within the light of these findings, it has been determined that both learning environments have different effects in increasing the success of the students and that the environment created for the experimental group is more effective in increase of the success. As a result of the qualitative analysis of the data collected by the researcher through the open-ended questionnaire, it was seen that the students reported positive opinions towards the environment (mobile technology, WhatsApp or virtual stock exchange application) and problem based teaching process. Based on these results, it can be asserted that the problem based learning process in which mobile based applications are used as an assistive technology is effective both in the increase of students' success in maths and their positive attitudes.

    (Anadolu University, Faculty of Communication Sciences, 2019) Cetinkaya, Levent
    This study aimed to investigate the relationship between parental psychological and behavioral control which the adolescents perceived from their parents and internet addiction. It employed relational survey model and was carried out with the participation of a total of 356 students (female=205, male=151) aged 14-18. Correlation and regression analyses were utilized to determine the level and direction of the relationship between their perceived parental psychological and behavioral control, and internet addiction. The results yielded a positive, medium-level and meaningful relation between them. It was found that parental psychological control explained nearly 18% of the total variance in internet addiction and mothers are perceived as significantly more psychologically controlling in internet addiction than fathers. Also, the relationship between parental behavioral control and the level of adolescents’ internet addiction was found negative and non-significant. Consequently, it was noted that perceived parental psychological control was effective in adolescents’ internet addiction tendencies, whereas behavioral control did not produce such effect. © 2019, Anadolu University, Faculty of Communication Sciences.
