The participant group constitutes 67 Pre-service students at a university in Black Sea Region of Turkey. Ten key concepts in General Biology course were given as a stimulating word and a mind map was established by using the frequency values of valid response words. The results showed that the total number of different response words for the key word {\textquotedblleft}enzyme{\textquotedblright} is the highest with {\textquotedblleft}cell{\textquotedblright} and {\textquotedblleft}energy{\textquotedblright} being higher than others and for the key word {\textquotedblleft}photosynthesis{\textquotedblright} is the lowest. The mind map also showed that they based their cognitive perceptions of the biological energy mechanism mostly on scientific concepts that are emphasized in the lessons and are academically acknowledged and included in the concepts used in everyday life at the least. However, they were not able to see the key concept {\textquotedblleft}enzymes{\textquotedblright} as a part of branched network and they had also problems regarding the respiratory event in the plants as well as realization process of photosynthesis in the cellular level. Implications of the results in terms of understanding the subject of biological energy metabolism are also discussed.}, keywords = {biological energy metabolism, cognitive structure, mind map, Pre-Service Science Teacher, word association test}, issn = {1648-3898}, doi = {https://doi.org/10.33225/jbse/18.17.462}, url = {http://oaji.net/articles/2017/987-1529509067.pdf}, author = {Ye{\c s}im Yener and Mehmet Bahar and Naciye Somuncu Demir and Mustafa Y{\i}lmaz and D{\"u}ndar Yener} } @article {340, title = {A CROSS-CULTURAL STUDY ON FRESHMEN{\textquoteright}S KNOWLEDGE OF GENETICS, EVOLUTION, AND THE NATURE OF SCIENCE}, journal = {Journal of Baltic Science Education}, volume = {13}, year = {2014}, month = {February/2014}, pages = {Continuous}, type = {Original article}, chapter = {6-18}, abstract = {The purpose of this study was to measure the freshmen{\textquoteright}s level of knowledge about genetics, evolution, human evolution, the nature of science, and opinions on evolution and the presence of non-scientific explanations among Czech, Slovakian, Slovenian and Turkish students. Determination of prior knowledge and pre-conceptions about these issues is important because they are filters to learning other related concepts. The results are going to be a starting point for developing teaching strategies concerning Darwinian evolution and preparing prospective science teachers for working with students in national and international contexts.

The findings can be summarized as follows: knowledge especially that of the nature of science at the freshmen level was seriously flawed. Non-scientific explanations were present in high percentages. Both were regarded as barriers towards scientific reasoning and acceptance of general human evolution especially for students expressing orthodox religious beliefs. }, keywords = {human evolution, nature of science, non-scientific explanations}, issn = {1648-3898}, doi = {https://doi.org/10.33225/jbse/14.13.06}, url = {http://oaji.net/articles/2015/987-1437062033.pdf}, author = {Andrej {\v S}orgo and Muhammet Usak and Milan Kubiatko and Jana Fan{\v c}ovi{\v c}ova and Pavol Prokop and Miro Puhek and Jiri Skoda and Mehmet Bahar} } @article {152, title = {SCIENCE STUDENT TEACHERS{\textquoteright} IDEAS OF THE HEART}, journal = {Journal of Baltic Science Education}, volume = {7}, year = {2008}, month = {August/2008}, type = {Original article}, chapter = {78-85}, abstract = {The purpose of this study was to find out the level of science student teachers{\textquoteright} understanding about the internal structure of the heart.
