The current study investigated the effectiveness of three distinct educational technologies--two game-based applications (From Here to There and DragonBox 12+) and two modes of online problem sets in ASSISTments (an Immediate Feedback condition and an Active Control condition with no immediate feedback) on Grade 7 students' algebraic knowledge.…

Existing literature on the impact of Common Core State Standards in Math has shown little benefit, but it has not examined variation in outcomes based on implementation strategies, student subgroups, or outcomes other than test scores. We use a difference-in-differences approach with school fixed effects to compare outcomes in pre- and…

This study used the Eccles et al. expectancy-value (E-V) theory to test the influence of motivation on mathematics achievement and enrollment using data from a cohort of 926 seventh-grade prealgebra students (49% male, 76% Hispanic, 76% low income, and 55% English learner). E-V beliefs were assessed in seventh grade along with achievement, and…

Efforts to improve teachers' knowledge and to change the nature of curriculum materials have dominated mathematics reforms since the late 1990s. In this article, we compared middle school teachers' mathematical knowledge for teaching (MKT) and curriculum use between 2005 and 2016 to assess progress toward these key goals. We found teachers' MKT…

This study uses student panel data to examine the association between algebra placement and student motivation for mathematics. Changes in achievement goals, expectancy, and task value for students in eighth-grade algebra are compared with those of peers placed in lower-level mathematics courses (N = 3,306). In our sample, students placed in…

This study examined sources of inconsistency between teachers' and researchers' interpretations of survey items. We analyzed cognitive interview data from 12 middle school mathematics teachers to understand their interpretations of survey items focused on one aspect of their practice: the content of their advice-seeking interactions. Through this…

Utilizing a nationally representative sample of middle school students, this article focuses on whether students who report experiencing more inquiry-based instruction in science and mathematics classrooms have more positive attitudes toward these subjects. Results of multilevel, multivariate regression analyses revealed that, net of the inclusion…

In a randomized field trial with 2,850 seventh-grade mathematics students, we evaluated whether an educational technology intervention increased mathematics learning. Assigning homework is common yet sometimes controversial. Building on prior research on formative assessment and adaptive teaching, we predicted that combining an online homework…
