This study investigated the senior high school (SHS) chemistry teachers’ perception of the use of simulation games (SGs) in chemical equations balancing (CEB). The study employed a type 1 developmental research design in which SGs were designed, pilot-tested and finally developed. The developed SGs were implemented and evaluated in a two (2) day workshop using 35 chemistry teachers (made up of 20 males and 15 females) drawn from ten (10) SHS in the Sekondi-Takoradi Metropolis in the Western Region of Ghana. Questionnaire and interview were the two (2) instruments used for the study. The findings showed that majority (33 out of 35) chemistry teachers representing 94.2% agreed that SHS students had learning difficulties with regards to simple CEB. Again, all the 35 SHS chemistry teachers representing 100% indicated that they enjoyed the use of SGs materials and instructional approach in teaching simple CEB and that they wanted more of the SGs materials to be developed and used in teaching abstract chemistry concepts. It was recommended that stimulating experiments such as SGs approach should be designed and developed to interest students in the exciting field of chemistry so that more students may be drawn into studying chemistry.

Grey water has been discharged onto this wetland for more than thirty years without any measurement of the quality of the influent and effluent. The effluent eventually joins a stream (Kakum River) which is a source of water for recreation, farming, drinking and fishing. The quality of the effluent which enters the receiving water as well as the potential of the wetland in the treatment process has not been determined. The purpose of this research is to assess the potential of the wetland in grey water treatment. Three communities in Cape Coast, the formal capital of Ghana were selected for this work. The wetland under study has an area of about 17,928m2 and hydraulic loading rate of 0.0164m/d. Field studies were conducted to demarcate the borders as well as to confirm the communities which discharges into the wetland. The results indicate that the wetland has very high potential in treating grey water, with suspended solids showing high removal efficiency. It was also inferred from the results that the wetland’s treatment is influenced by the precipitation pattern of the area and this is clearly shown in the removal efficiency of manganese. The findings will help decision makers to make proper laws concerning wetland use in Ghana. It will inform decision makers to officially consider wetlands as alternatives for grey water treatment. This paper assesses the potential of natural a wetland and makes recommendations on its proper use as well as its limitations.

The study aimed at investigating students’ conceptions on properties of matter- elements, compounds, mixtures, physical change, chemical change and the acid – base concept. It covered three representative schools with a population of four hundred and fifty students. These students completed a concept diagnostic test on basic introductory chemistry concepts necessary for the start of an elective chemistry course at Senior High School. Results indicated that beginning High school students have significantly gross misconcepts of greater than 42 % about basic chemistry concepts. This is statistically significant and will not auger well for effective teaching and understanding of further concepts. A lot of preparatory studies will be required before the commencement of a secondary school chemistry course for better grounding and understanding of chemistry concepts.

This was effected through micro practical activities to see how it enhanced pre-service chemistry teachers’ conceptual understanding. Data were collected from 48 pre-service chemistry teachers at the University of Education, Winneba in Ghana by means of a concept test, students’ responses in class and class work as well as a semi-structured interview. Results showed that pre-service teachers had some alternative conceptions about chemistry topics. A constructivists’ instructional strategy was used to help teacher trainees to reconstruct their concepts of many scientific phenomena.
