New technologies have been widely used in educational environments, as in every field. Web tools attract attention to make learning processes more efficient and to make students active. The microteaching method offers pre-service teachers the opportunity to apply new teaching. The purpose of this research is to determine the pre-service teachers' perception of web tools in micro-teaching and to analyze them according to various variables. The research was designed in a quasi-experimental design model. 75 pre-service teachers studying at the faculty of education participated in the research. Teachers' perceptions towards using web 2.0 tools in lectures scale was used as a data collection tool. As a result of the research, it was determined that micro teaching applications had a significant effect on the pre-service teachers' perception of web tools competence. Pre-service teachers stated that the use of web tools while teaching is beneficial in terms of drawing attention to the lesson and attracting the attention of the students.

This study aimed to develop an instrument to measure the perception of high school students regarding the relationship between chemistry and daily life and to determine the validity and reliability levels of the developed measurement tool. The data were collected from 7308 high school students from 59 provinces in Turkey. After the exploratory factor analysis was carried out to get an idea about the structure of the Perception Scale for Chemistry and Daily Life Relationship, the structure obtained was checked by confirmatory factor analysis. Originally consisting of 35 items, the load factor of the scale was decreased to 26 items following the removal of 9 items which were understood to be at a low level in item-total correlation and reliability. The Perception Scale for Chemistry and Daily Life Relationship consisted of 26 items and four factors: Awareness, Development, Interest, and Consciousness. These findings concluded that the scale obtained was valid and reliable in determining student perceptions about the relationship between chemistry and daily life. Teacher educators and chemistry teachers can use the instrument to determine high school students' perceptions of the relationship between chemistry and daily life. In this way, it may contribute to training students with potential for chemistry-related professions by implementing appropriate ways.
