摘要:This study investigated the mathematical competencies of secondary chemistry teachers in four types of process skills: measuring skill, computational skill, interpretative skill and translational skill. It used both quantitative and qualitative approaches and was guided by two major research questions: (1) what are the mathematical competencies of secondary chemistry teachers in the aforecited process skills? (2) What behavioral manifestations are associated with the chemistry teachers' level of mathematical competencies during teaching demonstration and classroom observation.doi: 10.3860/eacrb.v5i1.520 Emilio Aguinaldo College Research Bulletin Vol.5(1) 2006 p.45-46
