A case study using a phenomenological approach was carried out to determine how effective and enduring learning is for two diverse groups of grade 9 natural science learners when delivered through a collaborative co-teaching approach involving a high school science teacher and a special needs teacher. Even though the findings of this research indicate that the co-taught sessions did not significantly affect the learners’ test results, the majority of the learners reported very positive perceptions of co-teaching. From the findings the main benefits for the learners included an improvement in their understanding of learning styles and associated study skills, increased contact time with the teachers, and the benefit of another teacher’s expertise in the classroom. The researcher found the co-teaching approach yielded a clearer focus on the individual learning styles, new strategies for differentiation, and a positive teaching experience. / Science and Technology Education / M.

This study investigated the cognition of Form III English language teachers and evaluated their preparedness in implementing the revised English language curriculum. The study investigated teachers’ understanding of the integrated curriculum; described the relationship between teachers’ implementation strategies and curriculum requirements; established the effect of cognition on the process of implementation and determined challenges of implementation. A descriptive survey design was used in Eldoret East Sub-County in Kenya. Data was collected using a questionnaire and in-depth interviews, student focus group interviews, observation in Form III language classrooms, document analysis and journal entries. Data analysis was done by use of frequency and descriptive statistics. Qualitative analysis involved transcriptions of interviews and filed notes which were coded, categorized and patterns and themes identified. The study established that (1) teachers had varied cognition of the integrated curriculum (2) teachers showed integration at varying levels (3) more than 50% of the teachers still believe that English language and literature should be taught separately. (4) Teachers who had a better cognition of integration made more effort in the preparation and actual implementation of the integrated lessons. However, some teachers who did not seem to have any problem with conceptualizing integration still fell short of implementing it with fidelity (5) the practice of concentrating teaching on examination areas is still entrenched in teachers’ beliefs. Factors that were established to affect curriculum implementation efforts include: lack of appropriate Teacher Professional Development (TPD), content overload and complexity, non-suitable learner characteristics, inadequate directions in course books on integration and inappropriate pre-service training. The study recommends involvement of teachers in the development of curriculum innovations, organized Continuous TPD, development of materials that support teachers in their implementation and review of assessment procedures. This study has contributed to the dearth of literature in the area of teacher cognition of English language in Kenya. It has also provided insights to stakeholders in the field of curriculum on implementation issues that are pertinent which may lead to more fitting implementation in the future. This may help in suggesting necessary improvements to curriculum implementation such as material development, programme review at teacher colleges and universities and enhanced professional development training for teachers. The findings thus have a potential to inform and improve practice when stakeholders consider ways to improve the implementation of the curriculum in language classrooms in Kenya. / Curriculum and Instructional Studies / D.

This study aimed at identifying the models that best explain the student-related factors that contribute to the academic performance of students in the university. Students' final high school grade, English Language proficiency, self-regulatory learning strategies and extrinsic goal orientation are observed to generally have direct effects on the academic performance of the students in the university, while attitudes, intrinsic goal orientations, personality traits and age have indirect effects. Student mentors need to understand the factors that contribute to the academic performance of undergraduate students. Further research is also deemed necessary in other universities in Kenya in order to establish whether similar results would be obtained. / Educational Studies / D. Ed. (Philosophy of Education)

This study explored language practices of trilingual undergraduate students of mathematics as they made sense of an algebraic task. Specifically, the study set out to explore whether, how and why trilingual undergraduate students used language(s) to make sense of mathematics. In this study a trilingual speaker is viewed as an individual proficient in three languages and whose proficiency in the languages is not necessarily equal. The speaker uses the three languages either separately or by switching between any two in ways that are determined by his/her communication needs. Exploring language practices helped me to understand how students position themselves as they engage with a mathematics task using mathematical Discourses (capital D) in relation to their trilingual language facility. This facility involves the use of either the language of learning and teaching (LoLT) (English) or the switching between two or three of the languages they know. These languages were home languages, including Kiswahili of the students. In tertiary institutions, English is the LoLT while the home languages are neither taught nor used in the classroom. The study used a qualitative inquiry process, specifically a case study approach. It was conducted at a public university in Kenya with a focus on first-year engineering students with mathematics in their programme. Data were collected using a students‟ questionnaire, and clinical and reflective interviews. A structured questionnaire was used to gather the baseline data, which was used for the selection of 15 interview participants. The clinical interviews provided information on language use as the students engaged with the task, explaining each step of the process, while the aim of the reflective interviews was to identify, ascertain and confirm various actions and different languages and language practices that were not apparent during the clinical interview. The interviews were transcribed and 11 paired transcripts were selected for analysis. The data were analysed using the methods of Discourse analysis (Gee, 2005). This analysis explored how students used language in tandem with non-language “stuff” in a single language or when switching between any two languages and how and why each was used. The focus was on the activities and identities they enacted through their interpretation of the given task and in part of the solution process. The findings revealed that when students engaged with mathematics, they drew on the LoLT only, or switched between the LoLT and their home languages or between the LoLT, home languages and Kiswahili. Those who switched did so when they were faced with interpretation challenges, when there was need to emphasise a point and due to habitual practices of switching. They commonly switched silently and communicated verbally in the LoLT. The purpose for code switching was to gain understanding of the task. On the other hand, a trilingual student is likely to remain in the LoLT because content has been taught and tasks presented in the LoLT. The key contribution of this study is its focus on the trilingual language context of undergraduate students of mathematics, an area that has not been researched up to now. Furthermore, this study has added to scholarly work in this discipline by establishing that code switching is not the preserve of students who are learning the LoLT; rather, it is a reality for trilingual students who are competent in the LoLT when they engage with mathematics. / Mathematics Education / D.
