| Report on understanding students' concepts of slope using diagnostic tasks | The report of a study using diagnostic tasks as a means to assess students¡¦ learning in the concepts of slope. Based on the findings of the study, classroom learning tasks for conceptual understanding are suggested in the report. |
Basic Competency: KS3-MS13-2 use the formula slope =  (calculations on inclinations are not required) KS3-MS13-4 demonstrate recognition of the conditions for parallel lines and perpendicular lines |
