In order to achieve the purpose of the study three specific objectives were developed under this study: Firstly, evaluating teachers’ views towards the preparation and use of lesson plans. Secondly, assessing teachers’ knowledge base towards lesson plans preparation and use and thirdly, assessing the practicability of the prepared lesson plans in teaching and learning process. The study location was Igunga District of Tabora Region. The study employed a sample of 111 respondents among them 60 were teachers from four purposely selected primary schools, 40 were pupils and 11 were key respondents under the following ratio; four head teachers, five school quality assurance officers, one district academic officer and one ward educational coordinator. The data were collected using Interviews, Questionnaires, documentary review and observation were methods used during data collection Through teachers’ views, the findings revealed that there were negative attitudes, low knowledge base and little supportive environment towards the preparation and use of lesson plans to teachers from all primary schools which were included in the study. On top of that negative attitudes and low knowledge base towards the preparation and use of lesson plans to teachers seemed to have a direct proportion with low academic performance to pupils. The study recommends that educational leaders at school, district, and national level should ensure effective preparation and use of lesson plans to teachers through facilitating them with all necessary tools during the preparation of lesson plans, provision of frequent and sustainable training on preparation and use of lesson plans, as well as insisting and motivating teachers to prepare and use lesson plans effectively. On top of that the government should develop effective strategies which will ensure effective training on preparation and use of lesson plans in teachers’ collages.
