Subclaims¶

q2 i? The authors report media scaffolding supported (a) investigation of properties, (b) making concrete shapes of geometry mentally, and (c) completion of geometry tasks or problems. → Sutiarso 2018 q2 i? Charts shortened learning time, and props use cultivated cooperation among students. → Sutiarso 2018 (2)

Sutiarso 2018¶

Sutiarso, S., Coesamin, M., & Nurhanurawati. (2018). The effect of various media scaffolding on increasing understanding of students' geometry concepts. Journal on Mathematics Education, 9(1), 95-102. https://ejournal.unsri.ac.id/index.php/jme

q2 · i? · causal · r1

Authors' interpretation of the experimental results, illustrated by a kite-area example in which students modified a props kite into a rectangle to derive that the kite's area is half the rectangle's area.

"The findings of this study that the media scaffolding has been helping students in (a) investigation of the properties, (b) make concrete shape of geometry mentally, and (c) completion of a task or problem geometry."

q2 · i? · causal · r2

Authors' discussion of observed attitudes and practical benefits: charts presented images, brief explanations and worked examples, while "the students while using props have cultivated the attitude of cooperation among students" during modification activities.

"Chart has helped shorten the learning time of students."

Discussion¶

Learner Variables¶

• Geometric Reasoning — outcome: instruction changes it
