This study aimed to identify the difficulties that information technology student teachers have in teaching concepts. This qualitative study was carried out with 12 student teachers. The student teachers were fourth-year students enrolled in the Special Teaching Methods II course in the spring semester of the 2010-2011 academic year. The research data were obtained from three types of data resources: lesson videos, lesson plans and reflection reports written by student teachers. The lesson videos, lesson plans and reflection reports were subjected to a descriptive analysis process. In the study, it was determined that some student teachers could not distinguish concept knowledge, had misconceptions and difficulty determining conceptual features and used incomplete or incorrect concept definitions. Moreover, the student teachers did not use examples and analogies effectively during teaching.

Twenty-six years have passed since computers entered the Turkish Education System. Studies regarding the evaluation of the integration process reveal that the technology use has not yet been reflected into classroom activities sufficiently. This article aims to evaluate studies conducted from the beginning of the process to determine problems with regard to the integration process, especially by focusing on the elementary education. The article carefully examined the relevant literature, short-term action plans, circulars, regulations, project documents, and research studies. It appears that all the investments and projects carried out so far regarding the generalization of the use of ICT in education have remained mostly at macro level. More concrete policies and practices taking all the dimensions into consideration were put into practice only in the last period of the technology integration process. There are still problems at present situation particularly in the dimensions of infrastructure, teacher education, instructional materials, and software. Micro-level studies, which are carried out at the level of individual school, should be supported. Then, there will be better chances to convert the results of studies into policies for effective reform.
