The purpose of the study was to evaluate of Social Studies Teachers Knowledge in Nature, Goals, and Objectives in the Lesson Presentations The study adopted qualitative research approach. Data were collected through the use of individual interviews, observation and focus group discussions for triangulation purposes. Purposive, convenient and simple random sampling techniques were used to select the schools, teachers for the study. In all, seventeen (17) Social Studies teachers were selected from six (6) Senior High Schools. The study revealed that teachers were grossly deficient about the goals of Social Studies. To improve this system, it is recommended that the researchers suggests that the highest priority should be given to the training and development of a new breed of educator who are vocationally competent and academically sound. This can be done by heads of institutions to allow teachers who specialise in their respective areas to teach those subject areas at the various levels of education particularly Social Studies at the High school level.

The purpose of the study was to examine the impact of instructional materials in teaching and learning biology in the Colleges of Education in the Central Region of Ghana. Qualitatively, a case study research design was selected for the study. The population of the study consists of three Biology tutors in the three Colleges of Education in the Central Region. The purposive sampling technique was chosen to select all the three colleges and three Biology tutors for the study. The interview guide was the main instrument for the data collection. Data were analysed using the interpretative technique based on the themes arrived at during the data collection from the respondents. The study concluded that instructional materials boast students’ cognitive abilities and arouse their interest in the lesson by helping them to reason critically during teaching and learning. The study also revealed that the competencies level of tutors helps them in the assessment of the subject, selecting relevant materials for each concept. Their pedagogical skills depend on their competencies in the classroom instructions. The study also concluded that a good presentation of a lesson has a substantial impact on teaching and learning situations, as well as the vast amount of information available to students, to supplement their instruction and the principles for appropriate use of instructional materials. It is recommended that professional development should be organised for the Biology tutors in their respective colleges to have competencies in using relevant instructional materials in assessing students in Biology lessons. It is also recommended that Ghana Tertiary Education Commission (G-TEC), National Teaching Council (NTC), and universities should collaborate with the colleges to organise workshops and seminars for tutors teaching Biology to update their knowledge in the use of digital instructional materials in lesson presentation.
