Teaching Experience

Research Interests •The effect of geospatial factors (space and place) on mathematics classroom discourse. •Variation theory as a framework for redesigning and deconstructing standard tests with the view of creating a fair mathematical space for all the students •Pre-service teacher trainees’ emerging professional identities and how these might affect their teaching practice and adaptation to their first job postings as neophyte teachers. •The correlation between the acquisition of content and pedagogical content knowledge and productive mathematics classroom discourse. •STEM teachers’ conceptions and perceptions of integrated STEM and how these impact their classroom organization and student knowledge development and conceptualization of objects of learning. Research Experiences Aug 2022 to Present 1. Currently working with Mathematics Education faculty members at Purdue University in literature collection and review; objective setting, and data analysis on: •The effect of figured worlds on student and teacher professional identities and how this might impact mathematics classroom discourse 2. Working as a Research Assistant on a research project funded by NSF (BCSER: Characterizing how teachers to design engaging learning environments in STEM education). The research team is working in collaboration with Indiana K12 teachers to explore teacher conceptions and perceptions of Integrated STEM and how these impact the in-class organization and presentation. 3. Working with CATALYST (The Center for Advancing the Teaching and Learning of STEM) administration in organizing and planning for the Indiana STEM Education Conference to be held in January 2023 at Purdue University Jan 2021 to Aug 2022 1. Worked in collaboration with a Mathematics Education faculty member at Syracuse University and math coaches and elementary school teachers in Syracuse City School District in literature collection and review, objective setting, and data analysis on: •The effect of geospatial factors on algebra 1 performance in PreK-12 •Social justice, equity, and inclusion in mathematics teaching and learning space. 2. Investigating the use of case studies in training preservice teachers as a means of developing their identities as teachers and their pedagogical content knowledge in Kenya. 3. Investigated how students could enact teacher-endorsed sociomathematical norms in an undergraduate teacher trainee class at Syracuse University.

Research Interests

Teaching Philosophy

I view teaching and learning mathematics as healthy, productive, and vibrant mathematics
classroom interactions fueled by teachers' and students' positive mindset that is accessible and
makes sense of the mathematical materials and tasks. Mathematics teaching and learning should
be interactive, expressive, and involve sharing our experiences and relating them to the
conventional math curriculum (Masingila, 1993 & Kimani et al., 2016). Students should find an
opportunity to connect the in-class concepts with their daily out-of-class experiences using
mathematical tasks and materials (Pollak H., 1969). An enabling environment, expertly engineered
materials, and quality classroom discourse would be essential in developing their math abilities
(Collins et al., 2004). In relating in-class math activities to the out-of-school world, students would
understand their world, reflect on the past and present, and project the future (Sinclair et al., 2016
& Masingila, 1993). Through classroom interactions, students will develop critical thinking and
problem-solving skills by critiquing their thought processes and their fellow students' ideas or
experiences in open classroom discourse.
