A large amount of the water requirement of Konya City is supplied from groundwater. The quality of this groundwater was determined by taking samples from 177 of the wells within the study area. The purposes of this investigation were (1) to provide an overview of present groundwater quality and (2) to determine spatial distribution of groundwater quality parameters such as pH, electrical conductivity, Cl − , SO4 − 2, hardness, and NO3 − concentrations, and (3) to map groundwater quality in the study area by using GIS and Geostatistics techniques. ArcGIS 9.0 and ArcGIS Geostatistical Analyst were used for generation of various thematic maps and ArcGIS Spatial Analyst to produce the final groundwater quality map. An interpolation technique, ordinary kriging, was used to obtain the spatial distribution of groundwater quality parameters. The final map shows that the southwest of the city has optimum groundwater quality, and, in general, the groundwater quality decreases south to north of the city; 5.03% (21.51 km2) of the total study area is classified to be at the optimum groundwater quality level.

During the final marking period of 7th and 9th grades, students completed questionnaires assessing their academic self-concept and perceptions of the motivational context created by teachers, peers, and their economic opportunity structure. Achievement and discipline data were also collected at both time points. Ninth graders provided data on their motivation (effort and valuing of education) and future academic plans. Students reported more positive motivational contexts in 9th grade versus 7th grade, particularly with respect to teachers. Seventh-grade contextual variables were associated with 9th-grade motivation and adjustment. Discriminant function analyses found that 7th-grade variables discriminated between least adjusted and better adjusted high school students. Students'7th-grade discipline referrals, doubts about the economic value of education, and negative expectations of peers and teachers were the best discriminators between less and more adjusted 9th graders.
