In the present study, we employed the three-pronged approach to determine the actual cognitive processes theorized in knowledge revision. First, the Knowledge Revision Components (KReC) framework was identified as the guiding theory. Second, think-aloud analysis highlighted at which points in refutation texts readers detected discrepancies between their incorrect, commonsense beliefs and the correct beliefs, and the exact processes with which they dealt with these discrepancies-successfully or unsuccessfully, as indicated by posttest scores. Third, corroborating reading-time data and posttest data demonstrated that the structure of the refutation texts facilitated the coactivation and integration of the explanation with the commonsense belief, resulting in knowledge revision. Finally, an analysis directly connected the processes identified during think-aloud to sentence reading times. These findings systematically identify the cognitive processes theorized during knowledge revision and, in doing so, provide evidence for the conditions for revision outlined in the KReC framework.

Student-teacher relationships that improve over time may help slow or prevent declines in student motivation. In a diverse sample of 1,274 middle and high school students from three schools, this mixed-methods study found that those who improved in developmental relationships with teachers reported greater academic motivation, and more positive perceptions of school climate and instructional quality. Improvements in teacher-student relationships had some positive effects on students’ grade point averages (GPAs) but they varied by school as well as by aspect of the relationship measured. No differences by poverty status were seen in any of these results. Student focus groups yielded additional understanding of the actions and mechanisms through which student-teacher relationships improve. Results of this study suggest that if individual educators and entire school communities focus on strengthening student-teacher relationships, significant improvements can be made in students’ motivation, engagement, and performance.

We examined how middle‐school students’ motivation, belonging, school climate, and grade point average (GPA) are affected by students experiencing developmental relationships—those that go beyond teachers being caring (e.g., showing warmth to students) and providing challenge (e.g., high expectations) to also include teachers providing support, sharing power, and expanding students’ sense of possibilities. We also examined variations in those associations by student socioeconomic status (SES). The study included 534 diverse Grades 6–8 students (51% female, 46% non‐White, 33% eligible for free and reduced price meals). Structural equation modeling and regressions showed that students with better developmental relationships with their teachers had better outcomes. Developmental relationships strongly predicted academic motivation at both the beginning and end of the school year, and also directly predicted students’ sense of belonging and school climate. Relationships indirectly predicted GPA, through motivation. Student–teacher relationship quality for low‐SES students was lower and declined more than for other students. The results both reflect current literature in showing the importance of strong student–teacher relationships, and extend it in showing the worsening relationships quality for low‐income students, and in suggesting that strengthening multiple facets of student–teacher developmental relationships may have important effects on motivation and achievement of middle‐school students.
