Different representations of patterns have positive effects on the formation of the basis of algebra. Hence, it is important to investigate the strategies about pattern generalization for students' future learning about algebra. Thus, this study aims to define the generalizations about linear and quadratic patterns and also comparing the generalization strategies of 6th - 8th grades. The sample consisted of 18 students at 6th, 7th and 8th grades. The data collection tool has 4 problems and the collected data is classified through the generalization strategies in the related literature. The findings illustrate those at all linear and quadratic patterns, the variety and the correct generalization abilities are increasing due to the increasing of students' grades. Generally, most of the students used recursive or additive strategies, but only a few number of students used explicit strategies.

Determining the reflections of technology integration applications that are to be performed in our schools is important to light the way of first steps of integration. in this research, the effect of a web-based instruction environment used by 31 different teachers in a high school to school culture is set forth, The school culture is analyzed within the frame of thoughts and relations of teachers and directors and the spread of these applications that are new for the school Case study methodology has been applied in this study; the qualitative and quantitative data have Peen assessed together. The qualitative data of the study include the interviews with teachers, in-class observations, interviews with school directors; the quantitative data are obtained from the surveys applied on teachers. In addition to this, the records obtained from web-based instruction environment have been also used tor interpreting other data At the end of the study, positive changes have been detected over the thoughts and relations of teachers and directors. Moreover, during this research, even though there have been some exceptions, spread of web based instruction activities among teachers has taken Mace in parallel with the general technology diffusion theory. As a result we may say that thanks to this research, a culture based on the changes on the teachers and directors and school, usage of technology has started to be formed. Within this direction, the directors, teachers who are the important elements of school. culture for technology integration have made suggestions for the applications to he applied in school.
