Evaluation of the Effectiveness of Teacher Performance Appraisal on Professional Documentation in Public Secondary Schools in Gatanga Sub-County, Murang’a County, Kenya

Despite the importance of teacher, appraisal some contend that because of the way it is implemented, it falls short of expectations for stimulating curriculum implementation, which eventually shows up as low education performance. This study aimed at assessing how well teachers' appraisals on preparation of professional documentation affected the way the curriculum is implemented in public secondary schools in Kenya's Gatanga Sub-County and how documentation affects curriculum implementation in public secondary schools in Gatanga Sub-County. The research was directed by cognitive learning theories and documents used in the Gatanga Sub-County's public secondary schools' curriculum implementation. Taylor's Performance Monitoring Theory and cognitive theories of learning served as the study's guiding principles. The study used a contemporaneous triangulation research design with a mixed methodologies approach. 2282 (Krejcie and Morgan, 1970) respondents—42 principals, 811 teachers, 420 BOM members, 1008 PA Representatives, and one education officer in the Sub-County—was the study's target group. The researcher sampled 375 respondents—42 principals, 811 teachers, 42 BOM chairmen, 88 PA representatives, and one education officer—using the purposive sampling approach. The primary means of gathering data for the project was organized into teacher questionnaires and principal and Sub-County Education officer interview guides. The research instruments' piloting was in the nearby Kiambu County, 10% of the sample size was used for the research instruments' pilot study. The split-half approach was used to assess the instruments' reliability; if a correlation coefficient (r) of 0.78 is found, it was considered that the instruments are reliable. To assess the clarity of the research tool questions, content validity was assessed by supervisors and experts. The audit trail, which looks at the facts, processes, choices, and final product documentation, will show credibility and dependability. Descriptive statistics was used to analyze the quantitative data and display the results in tables; coefficient correlation was used to provide the inferential statistics, and themes and subthemes was used to analyze the qualitative data. Qualitative data was analyzed according to themes and sub-themes and presented narratively, while quantitative data was analyzed using descriptive statistics and shown in tables. Inferential statistics was provided through coefficient correlation.
