摘要：In Pakistan Mathematics is being taught by single teacher. In contrast coteaching has shown its positive effects on students’ academic achievement in Mathematics. Keeping in view the importance of co-teaching,this study was aimed at examining the co-teaching effectiveness to enhance students’ scores in mathematics. An experimental research design,Solomon Four Group was applied in this study to conduct an experiment. A school in the public sector was selected on convenient basis with due permission of headmaster. There were 118 students studying in that school at 8 th grade situated in Sargodha district. A teaching module of mathematics was developed on two content strands of 8th grade mathematics i.e. algebra & geometry. The duration for one lesson was one hour. There were 20 lessons in the module and were validated by two mathematics experts. Students’ achievement was measured by using an achievement test of mathematics. Pakistan National Educational Assessment System had developed and validated the items. Data were analyzed by applying Mean,Standard deviation,and independent sample t-test. Co-teaching was found to be more effective than single teacher’s teaching in enhancing students’ achievement score in algebra and geometry with mathematical proficiencies. It was recommended that a topic on co-teaching should be included in courses preparing teachers of Mathematics.
