Learners’ Perceptions of Computer-Assisted Instruction Approach Teaching and Learning of photosynthesis in Biology Lessons

Abstract The purpose of the study was to investigate the effect of computer-assisted instruction approach to the teaching and learning of photosynthesis on the performance of second year Senior High School (SHS 2) Biology students in science. The design for the study was a quasi-experimental research. This study was carried out in Sefwi Wiawso SHS and Asawinso SHS all at Sefwi Wiawso Municipal Assembly in [...] Read more.
The purpose of the study was to investigate the effect of computer-assisted instruction approach to the teaching and learning of photosynthesis on the performance of second year Senior High School (SHS 2) Biology students in science. The design for the study was a quasi-experimental research. This study was carried out in Sefwi Wiawso SHS and Asawinso SHS all at Sefwi Wiawso Municipal Assembly in the Western North Region of Ghana. They are all mixed institution. The purposive sampling techniques was used to schools, classes and students for the study. One-hundred one (101) electives biology participants were purposively selected, they consist of SHS 2 Science of (55) fifty-five students from Sefwi Wiawso SHS and SHS 2 Home economics of (46) forty-six students also from Asawinso SHS. The third years were not selected because they were preparing to write their WASSCE. The main instrument for data collection was questionnaire. The study collected only quantitative data and employed quantitative method of data analysis. Data obtained from participants in both experimental and control groups on the Test 2 were analysed statistically using independent-measures t-test. The independent-measures t-Test was used to investigate whether any differences existed between experimental and control groups’ mean scores on the Test 2. The study further revealed that computer-assisted instructions gives feedback to learners to have the opportunity to master computer-assisted instructional package tool used. It is recommended that, computer-assisted instruction method should be encouraged in many Biology classes in Wiawso Municipal Assembly, since it gives students opportunity to see links between concepts, summarise and organise their works, thoughts logically and sequentially. Both genders must be encouraged to use computer-assisted instruction method to studying Biology.

Evaluation of Teacher Support Materials (TSM) in Teaching Titration in the Senior High Schools in Ghana

Abstract A qualitatively, interpretative design was adopted to evaluate type of laboratory practical Teacher Support Materials that could be used to teach practical skills of observation, listening and communication and manipulation of apparatus in titration. The population of the study consisted of three public Senior High Schools (SHS) in Komenda Edina Eguafo Abirem (KEEA) municipality of the Central [...] Read more.
A qualitatively, interpretative design was adopted to evaluate type of laboratory practical Teacher Support Materials that could be used to teach practical skills of observation, listening and communication and manipulation of apparatus in titration. The population of the study consisted of three public Senior High Schools (SHS) in Komenda Edina Eguafo Abirem (KEEA) municipality of the Central Region of Ghana. Each school offers chemistry as a subject to students. Convenient, purposive and simple random sampling techniques were used to sample schools, teachers and students for the study. Six (6) teachers were purposively sampled out of a total of 8 chemistry teachers because they had qualification in Science Education in Chemistry. Five (5) students from each school were randomly selected from each of the three SHS for focal group discussion. The main instrument used for data collection were semi structured interview guide and Observation Checklist (OC). Teachers interview schedule was used to solicit information from the chemistry teachers on how they perceived the use of Practical Skills- based TSMs for teaching practical process skills in titration at the SHS levels. The curriculum profile was used to collect data to answer the research question. For each of the four Lesson Profiles (lesson introduction, skill development, application and closure) of the lesson plan, the total number of scores was divided by the maximum possible scores for the profile and expressed as percentage and qualitatively describing the trends of emerging themes. The study concluded that there has been some improvement in the cognitive experience and pedagogical content knowledge of the teachers as well as the students in the use of the PS-based teacher support material in the laboratory. It is recommended that teachers and educators should thoroughly read and assimilate the contents and the processes described in the PS-based TSMs before they are used in teaching titration so as to develop practical process skills of the students.
