Pathways to Student Motivation: A Meta-Analysis of Antecedents of Autonomous and Controlled Motivations.

Students' self-determined motivation (acting out of interest, curiosity, and abiding values) is associated with higher academic well-being, persistence, and achievement. Self-determination theory posits that self-determined motivation is dependent on the satisfaction of three psychological needs (relatedness, competence, and autonomy), which are in turn facilitated through need-supportive behaviors from notable others. In this meta-analysis, conducted over 144 studies and more than 79,000 students, we sought to overview pathways to student motivation in order to verify (1) how do psychological needs rank in the strength of their prediction of self-determined motivation and (2) which autonomy-support providers (parents or teachers) are the most relevant for psychological need satisfaction in students and self-determined motivation.

Student Motivation and Associated Outcomes: A Meta-Analysis From Self-Determination Theory.

Student outcomes are influenced by different types of motivation that stem from external incentives, ego involvement, personal value, and intrinsic interest. The types of motivation described in self-determination theory each co-occur to different degrees and should lead to different consequences. The associations with outcomes are due in part to unique characteristics and in part to the degree of autonomy each entails.

The tripartite model of intrinsic motivation in education: A 30-year retrospective and meta-analysis.

Introduction: Intrinsic motivation is a well-established concept in psychology, yet, different types of intrinsic motivation have not been thoroughly investigated. We examined covariates associated with three types of intrinsic motivation from self-determination theory (SDT) within the education context: IM to know, IM to accomplish, and IM to experience stimulation.

Methods: A meta-analysis was conducted on samples examining the tripartite model of intrinsic motivation between 1989 and 2019.

Reduction of hexavalent chromium using naturally-derived flavonoids.

Quercetin is a naturally occurring flavonoid that is known to form complexes with metals; a process that reduces the environmental availability of toxic metals such as chromium. We hereby report the first evidence of the removal of Cr(VI) from environmental samples using quercetin (QCR) and two synthetic derivatives: namely quercetin pentaphosphate (QPP) and quercetin sulfonic acid (QSA). We successfully synthesized both QPP and QSA using simple procedures while characterizing them with UV-vis spectroscopy, H(1)-NMR, (13)C NMR, (31)P-NMR, and LC-MS techniques.
