Pre-Service Teachers Achievement and Mastery Levels in Solid Geometry at E. P. College of Education, Bimbilla-Ghana

The purpose of the study was to determine Pre-Service Teachers (PSTs) achievement levels and self-evaluation of their level of mastery in Solid Geometry. The study used descriptive research design with purely quantitative approach to collect data related to Evangelical Presbyterian (E.P.) College of Education, Bimbilla-Ghana Pre-Service Teachers’. The population was one hundred and ninety-two (192) level 200 PSTs Pre-Service Teachers either majoring in mathematics, ICT or science. The sample used for the study was 140. Convenient, purposive and simple random sampling techniques were adopted. The instruments used were two comprising of achievement test and closed ended questionnaire. The overall results from the achievement test indicate that the PSTs were at good mastery level in solid geometry. Also, the self –evaluation questionnaire mastery levels for geometric properties, drawing of solid nets, finding surface areas were high and finding volume of solids were also very high. Finally, finding on composite solids area and volume was at moderate level. It was recommended that College Mathematics Tutors should encourage PSTs to always draw nets of solid shapes and also use solid nets to form solid shapes.
