q2 i? Teachers cited simplicity of representation and prior familiarity as reasons for preferring whole class bar and line charts. → Ali Raza 2024 q2 i? Teacher responses to the Choropleth Heatmap were polarized, with most finding it difficult and a few finding it easy due to prior familiarity. → Ali Raza 2024 (2)

Ali Raza, Tamara Sumner and William R. Penuel. (2024). The Science Student Electronic Exit Ticket (SEET) System: Visualizations to Help Teachers Notice and Reflect on Classroom Inequalities. Journal of Learning Analytics, 11(1), 87-100. https://doi.org/10.18608/jla.2024.8199

q2 · i? · qualitative · r2

Inductive grounded-theory coding of interview rationales from 42 teachers, with two coders reaching consensus. Teachers cited reasons such as simple/easier (24), helpful/quickest (9), and faster to get information (6) for the bar charts.

"Teachers reported that ease -of-use, simplicity, and familiarity with common chart types — such as bar and line ch arts — heavily influenced what visualizations they chose to use."

q2 · i? · design · r2

Interview coding of heatmap rationales: most teachers reported finding the heatmap very difficult, citing colours making it hard to read (17), too many colours (13), no previous experience/familiarity (17), and a high learning curve (8); 12 teachers found it easy, citing prior familiarity.

"Teachers' perspectives on the ease -of-use of the Choropleth Heatmap were polarized. A few teachers (12) found it easy-to-use, often citing their prior familiarity with these types of representations."
