In the research, the effect of engineering design-based STEM activities on the school belonging to seventh-grade refugee students was examined. A mixed-method was used in the research. The research sample consists of 32 Syrian refugee students studying in the 7th grade in the fall semester of the 2019-2020 academic year. The study lasted for ten weeks, with two lessons per week. In addition, the "School Attachment Scale for Children and Adolescents" was used as a quantitative data collection tool. On the other hand, qualitative data collection tools were used as "STEM Education Reflective Diary Form, STEM Education Interview Form, and Teacher Interview Form," which were prepared based on quantitative scale items. Statistical methods were used to analyze the quantitative data obtained in the research, and content analysis was used in the qualitative data analysis. The quantitative data showed a significant difference between the pre-test and post-test scores. As a result, It was concluded that the engineering design-based STEM activities carried out contributed positively to the individual and social development of Syrian refugee students; their positive attitudes towards the lesson and the teacher impacted their sense of belonging to the school.

The aim of this study is to develop a scale that will determine whether there is a significant difference in the cognitive, affective and behavioral attitudes of healthcare staff towards radiation and its effects on the variables of the profession, gender, service year, institution and department they work. Using the radiation-emitting devices consciously by healthcare staff will fairly reduce unnecessary radiation for patients. In this context, creating a positive attitude among the healthcare staff about radiation will positively affect public health. In this study, a Likert-type scale consisting of 18 items was developed to measure the attitude of healthcare staff towards radiation. The scale prepared in line with the purpose of the study was shared on-line on the web page of the All Radiology Technicians and Technicians Association and scale data were collected from 115 volunteer participants working as healthcare staff. The validity, reliability, and factor analyses of the scale of the collected data were analyzed with the statistical program. The developed scale had four factors and the 1st factor was determined as "The Radiation Knowledge of the Practitioner"; the 2nd factor as "Radiation Sensitivity of the Practitioner"; the 3rd as "Practitioner's Sensitivity to the Patient" and the 4th as "Practitioner's Informing the Patient". It is observed that the four-factored structure of the scale explained 64.5% of the total variance and the Cronbach's Alpha coefficient applied for the reliability of the whole scale was found as 0.914.
