a b s t r a c tThe purpose of this study was to determine the opinions of secondary school students in Turkey regarding renewable energy resources. To this end, a 26-item questionnaire, developed by Kılınç et al. [1], was administered to a total of 445 students in seventh and eighth grades. In addition, three open-ended questions were asked of the students in order to determine their level of knowledge regarding renewable energy resources and power stations. The study data were analyzed using the SPSS statistical package program. The study results revealed that most students first heard about the concept of renewable energy when they were in secondary school (55.7%) and elementary school (24.5%). In addition, the students generally knew about renewable energy sources and their importance, although they lacked knowledge about certain aspects of renewable energy. Furthermore, the students were, in general, of the opinion that electricity from renewable energy resources is cheap, reliable, and fully replenishable; that power stations producing electricity from these energy sources are generally safe and harmless to living organisms; and that their use does not contribute to global warming.
The aim of this research is to examine the awareness of science teacher candidates on recycling. Total 315 teacher candidates studying at first, second, third and fourth grade at the Department of Science Education have participated in the research. An awareness test that comprises of 5 open-ended questions has been implemented to the teacher candidates. It has been determined that the teacher candidates heard about the concept of recycling mostly through school, media and their families. It has also been determined that the teacher candidates are evaluating the recyclable material within the scope of packaging wastes. It has also been determined that despite almost all teacher candidates have the sufficient awareness concerning the meaning, necessity, purpose of recycling, they do not have the sufficient awareness about the recyclable materials. However, it is striking that the teacher candidates have not mentioned metal and composite packaging wastes. Yet, a few teacher candidate is aware of the meanings of the signs besides recycling and recovery signs that are on the packages. It is believed that the reasons behind the limited recycling awareness are lack of knowledge and interest and lack of importance about recycling on media and in education theoretically and practically.
As a chemistry education game, Ion Hunters was developed for university-level students to practice naming anions and cations and writing the formulas for ions that are frequently encountered in chemistry lessons. This game, which is played by two students at a time, is an effective tool for teaching about ions and makes the lesson more enjoyable by providing an opportunity for students to associate a chemistry topic with having fun. When the game is completed, the analysis sheet is used to determine which student has written the highest number of correct answers on the answer sheets; this student becomes the winner of the game.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
