Differentiating instruction for learners’ mathematics self-efficacy in inclusive classrooms: Can learners with dyscalculia also benefit?

Abstract

Poor mathematics self-efficacy (MSE) has been recorded among learners at all levels in Nigeria. The study reported on here sought to establish the efficacy of differentiated instruction (DI) in raising learners’ MSE in inclusive settings. We also explored the differential effects of DI on the MSE of learners with dyscalculia, as well as on high- and low-achieving learners. We adopted a control group quasi-experimental research design involving 1 experimental and 1 control group. A total of 4 mathematics teachers and 158 Senior Secondary II (SSII) learners in 4 regular classes participated in the study. Mathematics teachers participated in a one week DI training workshop to equip them with DI skills for whole-term mathematics instruction. The Students’ Mathematics Self-efficacy Scale (SMSES) was used for data collection at pre- and post-intervention evaluations. Quantitative data were analysed using descriptive statistics and analysis of covariance (ANCOVA). The major findings reveal that using DI led to significant improvements in learners’ MSE. Prior achievement (PA) had a significant influence on MSE; however, DI was effective in reducing the negative effects of poor PA on the self-efficacy of low-achieving learners and learners with dyscalculia. It was concluded that DI offers teachers the impetus to help all learners to improve their self-efficacy in mathematics.
