Direct linkLee, Mi Yeon; Lee, Ji-Eun – International Journal of Science and Mathematics Education, 2021
A task-based written survey was administered to 69 pre-service teachers (PSTs) at a large Midwestern University in the USA to examine their recognition of examples/non-examples of [one-fourth] presented in various forms of the area model, their perceived mathematical key points in identifying examples/non-examples, and their instructional…

Lee, Mi Yeon; Lee, Ji-Eun – International Journal of Science and Mathematics Education, 2021
To shed light on the value of the area model as a tool to elicit pre-service teachers' (PSTs') understanding of fractions and area, we explored their understanding of the fractional knowledge and geometric measurement knowledge incorporated in the area model by providing PSTs area models in an "atypical" way. We administered a written…

Son, Ji-Won; Lee, Mi Yeon – International Journal of Science and Mathematics Education, 2021
Despite the importance of teachers' conceptions of and competency in problem solving, limited attention is given to this area in the current literature. We examined 96 preservice elementary teachers' problem-solving conceptions and performances by having them define and create metaphors for problem solving and then investigated the relationships…

Lee, Mi Yeon – International Journal of Science and Mathematics Education, 2021
This study is an investigation of the possible relationship between clinical interview skills and teacher noticing. In a multiple case study, video-recordings of pre-service teachers' (PSTs') mathematical clinical interviews and their written critiques of a mathematics lesson were examined using qualitative content analysis. Findings suggest that…

Lee, Ji-Eun; Lee, Mi Yeon – International Journal of Science and Mathematics Education, 2020
This study is an investigation of elementary preservice teachers' (PSTs') exploration of model breaking points in fractions. Eighty-three PSTs at two universities in the Midwestern and Southwestern regions of the USA were asked to explore the area model of fraction addition through a series of tasks and explain their reasoning in determining its…

Lee, Mi Yeon; Hackenberg, Amy J. – International Journal of Science and Mathematics Education, 2014
To investigate relationships between students' quantitative reasoning with fractions and their algebraic reasoning, a clinical interview study was conducted with 18 middle and high school students. The students were interviewed twice, once to explore their quantitative reasoning with fractions and once to explore their solutions of problems…
