q3 i? Scores on five of the seven MDTP topics are significant predictors of students’ odds of achieving proficiency on the algebra I CST in grade 8, even after controlling for grade 6 CST scale score; a one percentage point increase on the integers topic is associated with a 26 percent increase in the odds. → Chun-Wei Huang 2016

q3 · i? · associational · r2

Logistic regression with MDTP topic mastery indicators and grade 6 CST scale score as predictors for the analytic sample; the study reports "a one percent-age point increase on MDTP topic area 6, integers, is associated with a 26 percent increase in the odds of achieving proficiency."

"Scores on five of the seven MDTP topics are significant predictors of students’ odds of achieving proficiency on the algebra I CST in grade 8, even after controlling for grade 6 CST scale score (table 6)."

Discussion¶

Learner Variables¶

• Algebraic Thinking — predictor: learners who differ on it differ in outcomes

Related Claims¶

• The Elevate Math summer program significantly increased algebra readiness, raising the share of students mastering at least three MDTP topic areas from 12 to 29 percent — related
• Grade 6 math CST proficiency alone is not an effective indicator of algebra readiness: students need a scale score of 367, about 0.27 SD above the cutpoint, to reach a 50 percent probability of grade 8 algebra I proficiency — related
• Revisiting grade 8 algebra placement with grade 7 math CST scores does not necessarily yield more accurate placement outcomes, because predictions from different assessments largely overlap — related
• When scale scores are used, prediction accuracy of grade 8 algebra I proficiency does not vary substantially across grade 6 CST, grade 7 CST, and MDTP assessments (75–78 percent) — related
• Using grade 6 math CST scale scores rather than proficiency status increases the accuracy of grade 8 algebra I placement decisions from 69 to 75 percent — related
• The Elevate Math summer program significantly improved math achievement of rising grade 8 students, with a treatment-control difference equivalent to 0.7 standard deviation — related
