The study focused on knowledge Base of chemistry Teachers’ Support Materials used in Teaching Practical Skills in Titration in the Senior High Schools in Ghana. The purpose of the research was to develop Teacher Support Material for the teaching of laboratory practical skills of Observation, Communication, Listening and Manipulation of equipment in simple acid-base titration. The population for the study were chemistry teachers and students in three Senior High Schools (Edinaman, Komenda and Eguafo) in the municipality. Convenient, purposive and simple random techniques were used to the municipality, schools, teachers and students for the study. The (six) 6 teachers were purposively sampled out of the total of 8 chemistry teachers because they had qualification in Science Education in Chemistry. Five (5) students each were randomly selected from every SHS in the municipality. The study concluded that, the practical skills (PS)-based teacher support materials designed for use in teaching fundamental skills of observation, listening communication and manipulation of equipment in titration was a way of showing Senior High School Chemistry teachers how to develop these essential science process skills in teaching titration. It is recommended that, Ministry of Education, Ghana Education Service and Ghana Association of Science Teaching (GAST) must ensure that Senior High Schools chemistry teachers are taught how to use the Practical Skills-based Teacher Support Materials (TSMs) to enable them develop practical skills of Observation, Listening, Communication and Manipulation of apparatus in their students as they teach titration.
