Abstract:
Information in biology plays a principal part in most angles of human life. Inspite of this critical part there's a concern for low achievement in biology in examination at secondary school level. The low accomplishment has been faulted on unseemly instructional procedures used by the teachers. Teachers are looking for teaching procedures that would address students’ accomplishment and inspiration towards learning sciences and especially biology. The reason for this investigation therefore was to determine the impact of the use of Advance Organizers on the students’ achievement and motivation towards the learning of biology in secondary school education in Kitui county. The investigation embraced Quasi-Experimental research design and in specific Solomon’s Four Non-Equivalent Control Group Research Design. The target population was 3260 form three students in Kitui Central Sub County. The accessible population was 252 form three students from four girls’ schools and four boys’ schools in Kitui Central Sub County. Purposeful sampling technique and simple random sampling was utilized to choose and assign schools in experimental and control groups respectfully. The research utilized Biology Achievement Test (BAT) and Students Motivation Questionnaire as tools for information collection. Legitimacy of the instruments was achieved through authorization from the Department of Education of South Eastern College Kenya. The instruments were piloted in a school within the neighbouring sub counties with comparable characteristics as examined schools. The reliability coefficient was assessed utilizing Cranach’s coefficient alpha and K.R 21 Formula. A reliability coefficient of 0.81 was obtained. Descriptive statistics (means and standard deviation) and inferential statistics (one-way ANOVA and t-test) were utilized to analyse the information. Hypothesis were tried at α=0.0 level of significance. Results of this research uncovers that the utilization of Advance Organizers altogether improves the achievement and motivation of students to learn sciences biology in particular. The researcher prescribes broad utilization of Development Organizers be communicated to directors, instructors and learner instructors of all grades and disciplines through on-going steady proficient improvement exercises.
