This study investigates assessment of teacher's awareness and the use of modern and scientific tools in teaching Biology in senior secondary schools in Oredo local government area of Edo State. Descriptive survey research design was used in carrying out the study. The population consists of thirteen (13) secondary schools and twenty eight (28) Biology teachers from which a sample of sixteen (16) respondents were randomly selected from the population. The instrument for data collection was a questionnaire designed by the researcher and the data collected from the instrument were analysed using frequencies and percentage. From the results of the findings, the study proved that there are inadequacy in the supply of modern and scientific tools in schools for Biology teachers. It also revealed that even though there were some available tools, they were not functional due to lack of electricity to power them, lack of time allocated to the subject and large class size. It was therefore recommended from the findings that: Biology teachers should be enlightened or given more orientation about the existence and use of modern and scientific tools; Government should provide sufficient and adequate modern and scientific tools to schools in the local government area for the efficient teaching and learning of Biology.

The investigation of Students Understanding of the concepts of Reproductive system in Biology (A case study of University of Benin), Two (2) research questions served as it's guidelines, and it used a descriptive survey study design. It sought to find out the common misconceptions among students regarding asexual and sexual reproduction in different organisms? How does the behaviour of specific anatomical features, such as the gular fold in lizards, influence their mating and territorial strategies?
The study employed a sample of undergraduate Biology students in University of Benin, Edo State and a total of (100) respondents which were collected from four departments. The researcher developed questionnaire titled Questionnaire on "Students Understanding of the concept of reproductive system in Biology" was used as the data collection tool. There are twenty (20) items on the questionnaire. To analyze the data collected, descriptive statistics such as Simple percentage and frequency were used.
The study find reveals the varying degrees of understanding and misunderstanding among Biology Students as regards to Reproduction concept. Across different items, the analysis indicates fluctuations in the percentages of correct understanding and misunderstanding. Notably, while some items witness relatively higher levels of correct understanding, others show a prevalent misunderstanding among Students. It was suggested that the government should hire skilled and experienced Biology instructors with adequate knowledge of Reproduction concept for schools in order to effectively teach and learn Reproductive system.
