Providing effective motivational support is a critical determinant of a successful online distance learning experience for students in higher education. In this study, we examined how students’ academic level and use of 8 motivational regulation strategies influence 3 types of student engagement: behavioral engagement, emotional engagement, and cognitive engagement. A total of 95 undergraduate and graduate students enrolled in online courses in 4-year universities in the United States participated in this study. A series of hierarchical regression analyses of undergraduate and graduate online students (N = 95) showed that behavioral engagement, emotional engagement, and cognitive engagement are predicted by different motivational regulation strategies after controlling for the academic level. Additionally, students’ academic level was found to be a predictor of cognitive engagement but not a predictor of behavioral engagement or emotional engagement. The results suggest that online course instructors, tutors, and designers should provide students with differentiated motivational scaffolding based on their motivational profile in order to promote different aspects of learning engagement. 相似文献

The current experimental study examined the effects of graphic organizers in a collaborative learning context where students constructed knowledge during online discussions. As the results could vary depending on how students interacted with the graphic organizers, this study compared two different approaches: instructor-provided versus student-generated graphic organizers. Thus, the purpose of this study was to investigate the effects of receiving or generating graphic organizers on students’ engagement in online discussions. Thirty-six graduate students enrolled in an online graduate course participated in the study. While analyzing an instructional design case, students were asked to discuss design issues in a randomly assigned group. There were three conditions: control condition without graphic organizers, instructor-provided, and student-generated graphic organizers. Major findings revealed that both generating and receiving graphic organizers facilitated students’ higher levels of cognitive engagement, and encouraged students to consider alternative views during the discussions. Without the graphic organizer, students tended to simply summarize previous messages or raise new issues rather than elaborating on previous topics. There was a significant finding regarding the ways of interacting graphic organizers. Students discussed more topics when they were given instructor’s graphic organizers rather than when they were asked to generate them. 相似文献

We used a comparative interrupted time series design to examine the impact of the Massachusetts' Wraparound Zone Initiative on student achievement, attendance, retention, and suspension. This initiative was designed to create coordinated district systems that allow schools to proactively and systematically address students' nonacademic needs. The state education agency awarded grants to seven high-need districts, each of which used the funds to support a select group of schools in implementing strategies that focused on school climate and culture, family engagement, systems to identify and address student needs, and community partnerships. Results from this study showed that students in Wraparound Zone schools performed better on state academic assessments than students in comparison schools, when considering prior achievement trends. Effects were statistically significant in the 3rd year of implementation. The impact on academic achievement was greatest for third- and fourth-grade students, and was particularly strong for English learners. There was no statistically significant overall impact on attendance, retention, or suspension. 相似文献

Recently, a polynomials-based integral inequality was proposed by extending the Moon’s inequality into a generic formulation. By imposing certain structures on the slack matrices of this integral inequality, this paper proposes an orthogonal-polynomials-based integral inequality which has lower computational burden than the polynomials-based integral inequality while maintaining the same conservatism. Further, this paper provides notes on relations among recent general integral inequalities constructed with arbitrary degree polynomials. In these notes, it is shown that the proposed integral inequality is superior to the Bessel–Legendre (B–L) inequality and the polynomials-based integral inequality in terms of the conservatism and computational burden, respectively. Moreover, the effectiveness of the proposed method is demonstrated by an illustrative example of stability analysis for systems with additive time-varying delays. 相似文献

By considering network transmission mode, this paper addresses the finite-time multi-switching synchronization problem for two kinds of multiple chaotic systems. For multiple same-order chaotic systems, we construct the general switching rules and analyze the existence of switching cases. The presented schemes guarantee the states of each derive system to be finite-timely synchronized with the desired states of every respond system in the different transmission paths and switching sequences. For multiple different order chaotic systems, we analyze a special multi-switching hybrid synchronization behavior, where part of the states are completely synchronized and the others belong to combination synchronization. Moveover, the easily verifiable criterion is derived for such synchronization. Finally, numerical examples are given to show the effectiveness of the presented theoretical results. 相似文献

The purpose of this qualitative study is to understand how educational scaffolding may explain changing patterns of student success in mathematics in the era of developmental education (DE or remediation) reform in Florida College System (FCS) institutions. Specifically, we apply the concept of scaffolding to underprepared FCS students who are at risk of dropping out or failing gateway courses (the first credit-bearing college-level class in a course sequence) because they lack the academic skills necessary to succeed in college-level coursework, particularly in mathematics. We present data from focus groups conducted at 10 FCS institutions, suggesting that a reduction of scaffolding in math remediation occurred in the areas of course sequencing, instruction, and coordination with academic support services following state-level policy changes. In light of these findings, we offer a discussion of practical recommendations for college administrators related to academic advising, instructional strategies in DE courses, coordination between developmental and college-level instructors, student success courses, and the integration of DE instruction with academic support. We also suggest directions for continued research on the effects of policy changes in the FCS and DE reform efforts across the country. 相似文献
