Abstract
The present study investigated constraints faced by chemistry teaching and learning. It also suggested possible solutions for addressing the identified constraints. A total sample of 138 respondents including 125 students in chemistry combinations, 10 chemistry teachers and 3 directors of study were chosen purposefully to participate in this study. A qualitative research method using case study design was employed to gather necessary data. Content and thematic analysis methods were used to analyze the data. The results revealed that abstract nature of some chemistry concepts, lack of laboratory apparatus and chemicals, lack of laboratory technician to support chemistry teachers are major constraints faced by teaching and learning of chemistry. This study suggested that government and educational stakeholders should supply adequate chemicals and apparatus, chemistry teachers must use hands-on activities and video simulations to concretize chemistry concepts. Chemistry teachers should also motivate learners to enjoy chemistry to reduce negative attitude of students towards chemistry. Lastly the recruitment of laboratory attendants was also suggested as a major strategy to support chemistry teachers in preparation of chemistry practices.

Summary
Science understanding has a great impact on the development of science and technology. Professional and well skilled people are needed for better science understanding. Chemistry as one of science subjects contributes to the development of industries and social well-being of people. To produce competent and well skilled professionals in the field of chemistry education, requires a deep understanding of how chemistry is taught and how constraints encountered while teaching and learning chemistry are addressed. It is through this context, this study was designed to reveal constraints that hinder the effective chemistry teaching and learning towards searching alternative strategies to address them.
