Erol, Mustafa; Oğur, Mehmet
This study reports an Arduino based STEM education material that resolves large angle pendulum, alternatively anharmonic oscillator, both experimentally and theoretically, particularly focuses on the time dependence of the instantaneous displacement angles. Instantaneous time dependence of the angles is experimentally measured by using Arduino Nano microprocessor connected to a gyro sensor and a bluetooth transmitter/receiver structured as a STEM education material. Theoretical resolution of the large angle pendulum is also accomplished by considering the approximate solution taking into account the relevant frictional effects. The theoretical and experimental resolutions are managed for the initial angles of θ0 = 1.40 rad and θ0 = 2.61 rad, specifically focusing on the angular frequencies, frictional effects and anharmonicity of the motion. The relative errors concerning the angular frequency are found to be % 15.2 and % 6.5 for θ0 = 2.61 rad and θ0 = 1.40 rad, respectively. The exponential decrease due to the frictional effects are in perfect agreement with each other and providing a friction coefficient of γ = 0.015kg ms−1 for both experimental and theoretical results. The anharmonicity of the pendulum is also illustrated by comparing the experimental plots and relevant theoretical plots for the small angle approximations. This work offers a prototype teaching material which can create an education environment where students can feel dynamic and encompass the acquisitions of Science Technology Engineering and Mathematics.

Aydın, İ. Seçkin
The purpose of this study is to evaluate the self-efficacy perceptions and writing anxiety of the Turkish language teacher candidates that receive training for learning and teaching language in a processual context. The research has been carried out with a total of 113 teacher candidates that study at the Department of Turkish Language in the first (n= 56) and third (n= 57) grades. The reason is that the first graders are beginner and they receive Written Expression classes; and the third graders receive Writing Education classes. The data from both grades have been collected by using the Writing Self-efficacy Perception Scale (WSPS) and the Writing Anxiety Scale (WAS) at the beginning and at the end of the term. The collected data have been analyzed both in respective class levels and by comparing to the other class level. The result of the research shows that the writing anxiety has decreased and the writing self-efficacy perception has increased in the first grader candidates. Whereas in the third grader candidates, the writing anxiety has increased and the writing self-efficacy perception has decreased. This has been interpreted as the professional awareness of the candidates increases depending on the grade level. Another result of the research is that the revision and editing (RE) factor in the writing process is higher in the female candidates than the male candidates. The findings obtained in the research bear a resemblance to the literature in some aspects, and differ from the literature in some aspects.

The aim of this research is to identify perceived efficacy of a group of preservice teachers regarding selection of teaching methods and techniques. It seems important for preservice teachers to benefit from teaching methods and techniques in terms of learning processes in different subjects as they practice their profession. As this is a descriptive study, the survey model was used. Data were collected with Preservice Teachers’ Perceived Self-Efficacy in Selection of Teaching Methods and Techniques Scale, developed by Durdukoca et al. (2017). The study sample comprised of 321 fourth-year students in departments of Primary Teacher Education, Turkish Teacher Education, Social Sciences Teacher Education and Preschool Teacher Education in Buca Faculty of Education at Dokuz Eylül University during Spring Semester of the academic year of 2017-2018. Obtained data were analyzed with SPSS 22, ANOVA and t-test. Data analysis showed that the preservice teachers had high perceived self-efficacy in selection of teaching methods and techniques and that there was a significant difference between the participants from different departments.
