Improvisation are materials that are used in absent of the original or ideal object to bring about the same learning effect that the standard material would have brought (ahmed 2008). it seems to be the opposite of teaching, which requires proper planning and advance thinking. Moreover, the students of G.S kabarondo B require the improvisation in other to increase performing especial in chemistry due to lack of the laboratory. it is known worldwide that laboratory equipment and teaching-learning material are factor influencing students ‘performance in science especial in chemistry. Franzer et al.(1992) cited that professionally qualified science teacher no matter how well trained, would unable to put his ideas into practice if the school have insufficient of equipment and material necessary for him or her to translate his competence into reality and also TLM are the most important in knowing science in real life. Franzer et al, Abdullah (1982) cited that TLM are materials or tools locally made or imported that could make tremendous enhancement of lesson impact if intelligently used. This means that TLM is the most important in useful in teaching and learning science and they affect students’ performance in sciences permanently. Based on science education in African countries is at most universally in-adequate. He showed that African has the problem in science especial in RWANDA where the big number of students they don’t liked sciences, this brought the problem of lack of doctors, engineers and researchers.

Different educationalists claim that improvisation have a role to play in performance of students in science subject especial in chemistry S1students.when teaching and learning process was done by using improvisation, the performance of S1 learner was increased or improved. The act of teaching and learning by using improvisation is fundamentally concerned with ideas, skills and attitude from teacher to the learner and learner discover the lesson and understand, enjoyable that lesson. During the progression of my observation I have seen that spoken words alone in the learning instruction were ineffective and inefficient in producing out came of learners in performance. After each evaluation done in class, I saw that the result of learner was released out; there had always been failure in the work and quiz prepared.

However, the use of improvisations materials during the lesson especial in S1 chemistry during teaching and learning of science subject (chemistry) is the only way of increasing the performance of the student conducted an action research at GS KABARONDO B based on information given above, I observed that the learners in ordinary level especially at GS KABARONDO B in S1 students were not performing well in science subjects due to the lack of laboratory resources; therefore, there is a need of using improvisation materials to concretize the lesson or the lesson more understandable.

1.3 Research objectives

This research aimed to attain the following objectives;
? To demonstrate the importance of improvisation in performance of learner of S1 in chemistry.
? To apply improvisation strategy in improving performance of learners in chemistry subject at GS kabarondo B
? To assess the efficacy of this strategy in increasing performance of S1 in chemistry.
1.4 Research Question
This study was guided by the following research question:
? What is the importance of Improvisation in of teaching and learning?
? how can improvisation be applied in teaching and learning science at GS kabarondo b?
