research on laboratory activities and their influence on students achievement

The attainment of educational goal doesn’t depend only on the manpower but also on the availability of financial and material resources needed to promote educational activities. Laboratory work is a prominent and distinctive feature of Biology /science education. Many Biology/science teachers and others see laboratory work carried out by the students themselves1 as an essential element of good Biology/science teaching. . It must make him ready for the life as good as possible and a useful member of his community. This will be done when the teacher based on laboratory activities than theoretical. To think about what we mean by the ‘effectiveness’ of a teaching/learning activity, it is useful to consider the stages involved in developing and evaluating such an activity.

This action research entitled “Relevance of practical works on teaching and learning biology in ordinary level, secondary education, was carried out at G.S NYAKINAMA I” with the purpose of exploring the relevance of practical work on teaching and learning biology. The total population of this study was 328 persons which make a sample of 81 participants using Yamane formula. The latter wase composed by 76 students, 3 staff members and 2 biology teachers. The sample was selected using purposive sampling, probability and non-probability sampling methods based on the information for the study. The primary data for this research was collected using structured interviews and questionnaires. Class tests were also used to evaluate student’s performance. The data was collected by using Microsoft excel and presented in tables. In our study, we found that teachers do not use practical work as it should. All respondents agreed that they gain many skills from practical works at 100%. Teachers’ views indicated that 38.75% of the respondent confirm that insufficient time for practical works in biology is a barrier while 61.25% disagree. However, 48.75% agree that class size is not a challenge while 51.25% disagree. This study indicates that too long syllabus is a challenge agreed 27.5% and disagreed at 72.5%. For implementation of laboratories, results show that 75% agree that it is a challenge while 25% disagree. Therefore, practical works influenced learner’s understanding ability of lesson and retention of factual knowledge. Learning through theory good performance for 13 students (17.105%) and 63 students (82.8947%) failed while learners’ performance in biology through. Practically, the learner’s performance was increased where 62 students (81.579%) from ordinary level succeed and 14 students (18.4211%). Finally, the recommendations were given. The science teachers have to look at specific experiments and give them to students and let them be responsible for themselves in order to know that they should do even in the absence of a teachers. School administration should advice all teachers to use surrounding environment to create teaching aids to use in teaching and learning process. MINEDUC should provide materials to schools and advise teachers to adapt themselves on the use of improvisations.
