摘要:In order to advance models of educational processes (intraindividual, intensive longitudinal), we propose a model in which we specify state and trait constructs, and an intraindividual variability construct. In our ecological momentary assessment study, we investigated how trait-level and intraindividual variability of students’ learning experiences (intrinsic and extrinsic motivation, task difficulty, effort exertion, help-seeking and competence evaluations) converged with teacher-reported student task-focus. 285 primary school students’ (Years 5 and 6) completed the Learning Experience Questionnaire using handheld computers, on average 13.6 learning episodes during one week (SD = 4.6; Range = 5-29; nepisodes = 3,433), and these were linked with teacher-reports. We defined mean squared successive differences (MSSD) for each indicator. We specified uni- and multivariate models of state, trait and intraindividual variability constructs of students’ learning experiences using multilevel structural equation models (MSEM). Teacher reported task-focus converged with trait constructs (from |r| = .22 to .42), and with intrapersonal variability constructs (from r = -.12 to r = -.36), higher task-focus being associated with less variability. Intraindividual variability formed a higher-order construct, and teachers’ negative wording bias was also associated with variability. Overall, our study provides support for intraindividual variability as a construct in its own right, which has the potential to provide novel insight into students’ learning processes.
