Development and Standardisation of Mathematics (Geometry) Classroom Interaction Sheet (MgCIS) 2023

This paper was designed to develop and standardise Mathematics (geometry) Classroom Interaction Sheet (MgCIS) to observe teaching and learning activities at the senior secondary school level in Nigeria. Instrumentation design was adopted. Face and content validities of MgCIS were established. The final MgCIS has eight categories and 66 behaviours. The validation and standardisation procedures of the MgCIS involved several procedures. Data analysis was done using Cohen’s Kappa intra-class estimate for inter-rater reliability to obtain the correlation coefficient of observers’ level of agreements (r=0.87 to 0.99) using IRR package in R software version 4.2.2 for each teacher pair observed, while the construct reliability yielded r=0.99. The MgCIS was found to be consistent and highly reliable. It was recommended that policy makers and school administrators should encourage proper teaching of Mathematics, while head teachers and researchers interested in Mathematics (geometry) performance, should adopt the MgCIS to evaluate teaching.
