3 Data Analysis
The articles reached within the context of the study (publication year, physics subject titles, research titles,
research methods, research models, data collection instruments, sampling type and size, data analysis
techniques and numbers, number of authors, number of sources used) are evaluated under ten basic titles and
then their descriptive analyses are performed. With the aim of establishing a common language for classifying
the studies that will be carried out in the field of physics education in future years, the previous studies were
analyzed and the titles used by Kayhan and Koca (2004) were rearranged. If a study contains two or more
dimensions, each dimension is dealt with separately for the so-called characteristic. While evaluating the
sampling, for example, if both teachers and students are used, the so-called study is coded in two different
categories. The evaluated studies are coded by getting separated into subtitles under ten basic titles and the data
gathered were analysed through the use of Microsoft excel 2013. The results are descriptively presented with
the tables of percentage and frequency as well as graphics.
