The purpose of this research was to analyze the impact of an inquiry-based word problem-solving framework, known as Cognitively Guided Instruction (CGI), on students’ mathematical mindsets in an early elementary Montessori classroom. Students received one word problem-solving lesson per week over a six-week period. Students completed a pre-intervention and post-intervention mathematical mindset rubric, as well as CGI assessment. Both qualitative and quantitative results show that students had an increase in their variety of word problem-solving strategies, were able to solve word problems more accurately, and showed increased levels in self-efficacy, perception, and affinity towards math. Based on these results, CGI could be utilized as a supplementary instructional method to build students’ mathematical mindsets and word problem-solving skills in Montessori classrooms. Further research is needed to know if these results hold true for other student populations.
