The book was to examine land management in Wa Municipality. Case study research design was employed for the study. Purposive sampling technique was employed to sample 20 government officials and 60 traditional leaders for the study. Both the primary and secondary data were used. Questionnaires and interview guides were used to collect data from respondents. The findings revealed that majority of the respondents agreed that Tindanbas, chiefs, individuals and family heads are stakeholders in land management. It also showed that stakeholders were responsible for the selling of land, settling of land disputes and preserving the land for future generation. The findings further revealed that the government officials agreed that vested lands should be managed by government officials. On the contrary, all the traditional leaders are of the view that all traditional lands should be managed by traditional authorities. The study further again revealed that multiple land sales, conflict between modernity and traditional authorities, use of non-permanent boundaries and corruption are the major challenges facing land management.
The target population included 392 school teenage mothers drawn from 144 public secondary within Uasin-Gishu County. Stratified random sampling technique was used to select the public secondary schools while the purposive sampling technique was used to select the respondents of the study. Data was analyzed by use of descriptive and inferential statistics. The major findings from the study showed that teenage motherhood negatively affected academic performance due inability to raise funds to feed themselves and their children. Constant absenteeism and lack of adequate time to accomplish school tasks due to divided attention led to repeating of classes which in turn affected their self-esteem and confidence. It was also established from this study that most schools had strategies in place to enhance mother return to school policy which included a no-abortion policy and guidance and counseling services. Conclusions arising from the findings are as follows: Most of the teenage mothers are not able to attend school five days a week; majority of the respondents have repeated classes involuntary and their self-esteem is low due to hurdles they face in their schooling.

The main objective of the study is to assess the communicative grammar teaching methods used by teachers in relation to the theory of communicative language teaching. Yirga Cheffe, Dilla, Cheleleketu and Gedeb Preparatory schools were selected as a study area. To select the subjects from students, systematic sampling technique was used. As to the teachers, all teachers who taught English in grade 11 were included in the study. The result of the study indicated that the teachers were teaching grammar deductively to explain the rules in the form of summary. The data also showed that the teachers were not frequently incorporating different grammar teaching techniques to contextualize the grammar lessons. In these schools, the de-contextualized and isolated nature of the tasks and lack of skill in some teachers were found to be the major hindering factors in implementing communicative grammar teaching. As a result, based on the result of the study, it is concluded that the teachers teach grammar explicitly. Finally, some recommendations were forwarded based on the main findings of the study.
