Effect of molecular model kits on naming organic compounds in chemistry amongst winneba senior high school students

Abstract

The study examined effect of molecular model kits on naming organic compounds in Chemistry amongst Winneba Senior School Students in the Effutu Municipality. Simple random sampling technique was used to draw a sample size of 44 for the study. Students were taken through a lot of intervention activities using the molecular Model kits. Questionnaire and achievement test were used as an instrument for data collection and the findings were analysed using frequencies and percentages. Descriptive statistics was used to analyze the Pre-test and the Post-test. The Statistical Package for Social Scientist (SPSS) was also employed to analyze the Pre test and the Post-test scores by the students quantitatively using paired sample t-test. The major findings revealed that the models were effective in teaching and learning of IUPAC nomenclature of hydrocarbons. Further, the results showed that most of the students exhibited positive attitudes towards the use of the molecular model kits. The study recommends that chemistry teachers should be encouraged to incorporate teaching and learning materials in teaching concepts to make it as practical as possible. Also, educational programmes, workshops and seminars on the use of molecular model kits and other strategies should be organized for teachers on their effective use for teaching in the chemistry classroom.
