This study investigated the effect of using the technical visual arts lessons' material on visualization skills and attitudes. For this purpose, an augmented reality application called BTRS was designed. The application was created using Unity3D, 3Ds Max, and Vuforia programs. The study was conducted for eight weeks, with a total of 33 students (26 boys and seven girls) attending a vocational and technical high school. The study was designed based on Creswell's sequential explanatory design. While a semi-experimental method with a pretest-posttest control group was conducted for the quantitative part of the study, semi-structured interviews were used for the qualitative component. "Lappan Spatial Visualization Skill Scale," "Purdue Spatial Skill Scale," "AR Attitude Scale," and semi-structured interview form were used at the beginning and the end of the application. The Mann-Whitney U, paired-samples t-test, and the Wilcoxon signed-rank test were used for quantitative data. Qualitative data were analyzed by the descriptive analysis method. The study results indicated that the Augmented Reality Application did not significantly affect the achievement of the students and their spatial visualization skills. However, it has been observed that students' excitement and curiosity increased. The students reported that the material was enjoyable, fun, attractive, remarkable, helpful, easy to use, understandable, and persistent. Rotating, zooming, and moving interactive digital models and buttons in the real world have attracted the students. The experimental group described abstract concepts and required spatial thinking skills to be more explicit and more practical.

This study examines the effect of using a personal response system (PRS) on students' academic performance and attitude towards science and technology. The study is conducted during the spring semester of the 2018-2019 academic year in a secondary school in northwestern Turkey. The study is designed as a pre-test and post-test control group design, with 21 in the control group and 23 in the experimental group. The Science Achievement Scale and the PRS Attitude Scale were administered to 92 students in the pilot study during the scale development process. The study is conducted on one unit in the course syllabus called "The World of living things and indispensable part of our lives: electricity." The researcher worked with the group two hours a week for six weeks. Every week after the lecture, the class teacher made their students solve multiple-choice questions with PRS in the experimental group and paper-based in the control group. The quantitative section of this study included three tools: the Achievement Test, the Attitude Toward Science Scale, and the Attitude Toward PRS Scale. Although results showed no difference in achievement between pre-test and post-test scores in both groups, the experimental group showed a promising difference in their attitudes toward science. In addition, boys were more positive about PRS than girls based on the PRS attitude scale. The qualitative component involved focus group discussion with a random sample of six surveyed students and an interview with the class teacher. Students provided positive feedback regarding the use of PRS. They appreciated peer discussions that instructors facilitated while using PRS. The teacher was likewise enthusiastic about implementing PRS in his class.

Nomophobia, a type of technological addiction defined as the fear of being deprived of a smartphone, is quite prevalent in young individuals with the widespread use of mobile phones. This study aims to determine the nomophobia level of secondary school 8th-grade students. The effect of nomophobia on academic achievement was investigated by comparing the detected nomophobia levels of the students and the High School Entrance Exam (LGS) scores. These effects on LGS scores were determined by gender, parental attitude, parental education level, smartphone usage purpose, daily smartphone checking frequency, whether or not to carry a charger, areas where the smartphone is mostly used, and checking the smartphone before going to sleep. For this purpose, a correlational survey model was used in the study. The "Personal Information Form" and "Nomophobia Scale" were applied during the 2019-2020 academic year. According to the results of the research, nomophobia in secondary school students differs according to gender, the purpose of using a smartphone, the areas where the smartphone is mostly used, whether or not to carry a charger or not, whether or not to have a smartphone with them before going to sleep; while parental attitude, parental education level, daily smartphone checking frequency doesn't differ their nomophobia. It was determined that the students had moderate nomophobia levels, and the nomophobia sub-factor scores differed according to students' LGS scores.
