This article reports on an empirical exploration of the relations and strengths among Turkish grades 9–11 students’ (n = 209) personal epistemologies (justification of knowledge, certainty of knowledge, source of knowledge, development of knowledge), self-regulated learning (extrinsic motivation, intrinsic motivation, rehearsal, elaboration, organization, critical thinking, metacognitive self-regulation), and achievement in physics (course grades). Established instruments were used to collect data on these students’ beliefs about knowledge and components of self-regulated learning (SRL) such as goal orientations (extrinsic and intrinsic motivation) and learning strategies, critical thinking, and metacognitive regulation. Results from structural equation modeling revealed that students’ personal epistemologies directly influenced their motivation (extrinsic and intrinsic goal orientations), rehearsal and organization strategies, and metacognitive self-regulation to learn physics. Furthermore, students’ personal epistemologies indirectly (mediated through motivation beliefs) influenced rehearsal, elaboration and organization strategies, critical thinking, and metacognitive self-regulation to learn physics. Students’ ideas about knowledge and knowing about the source and development of knowledge significantly contributed to students’ self-regulatory skills and physics course grade. Implications and future directions are discussed. 相似文献

The Texas Electronic Coalition for Physics was established in 2000 as a means of demonstrating that by linking together, small
programs can maintain their vitality in higher education. Using Interactive Television, the Internet, telephones, faxes, and
other electronic media, five physics programs scattered across the state of Texas formed a distributed physics department.
In addition to jointly offering lecture courses, the group (i) established procedures for operating as a unified entity, (ii)
encouraged research regardless of location, (iii) provided a locus for professional camaraderie, (iv) created a distance-based
advanced physics laboratory course, and (v) developed assessment tools for measuring success in a distance environment. Through
these, the coalition demonstrated that a distributed department can carry out all of the functions associated with a traditional
department. 相似文献

A discriminal distance analysis procedure similar to that used by Roitblat (1980) was employed to test the hypotheses that animals either retrospectively (Spetch & Wilkie, 1983) or prospectively (Kraemer, Mazmanian, & Roberts, 1985) encode durations of events. Pigeons were required to discriminate 2-, 8-, and 10-sec presentations of light. Choices of red, orange, and green keys were correct after 2, 8, and 10 sec, respectively. The key elements in this design were (1) that some samples (8 and 10 sec) and some choice stimuli (red and orange) were more difficult to discriminate than were others, and (2) that an easy sample discrimination (2 vs. 8 sec) was mapped onto a difficult choice discrimination (red vs. orange), and vice versa. An examination of raw error scores and calculated confusion indexes in three experiments supported the hypothesis that subjects retrospectively, rather than prospectively, encode event duration. 相似文献

The widespread perceptions associated with digital technology and the internet are forcing publishers to look to ways to shift the balance of the burden of cost away from the user. We describe seven examples of ‘free’ distribution and discuss how they impact publishing business models. 相似文献

This Monte Carlo study investigated the impacts of measurement noninvariance across groups on major parameter estimates in latent growth modeling when researchers test group differences in initial status and latent growth. The average initial status and latent growth and the group effects on initial status and latent growth were investigated in terms of Type I error and bias. The location and magnitude of noninvariance across groups was related to the location and magnitude of bias and Type I error in the parameter estimates. That is, noninvariance in factor loadings and intercepts was associated with the Type I error inflation and bias in the parameter estimates of the slope factor (or latent growth) and the intercept factor (or initial status), respectively. As noninvariance became large, the degree of Type I error and bias also increased. On the other hand, a correctly specified second-order latent growth model yielded unbiased parameter estimates and correct statistical inferences. Other findings and implications on future studies were discussed. 相似文献

The relationships among science and engineering attitude, physics conceptual understanding, and physics achievement were explored for a population of college freshman engineering students over two semesters. Gender and SAT‐Quantitative measures were included as exogenous variables in a longitudinal path analysis. Attitude was theorized to predict achievement contemporaneously and at the next time point, while conceptual understanding was theorized to predict physics achievement contemporaneously and at the next time point. Each at one time was theorized to predict scores at the next time. A sample of 200 freshman engineering students participating in an integrated curriculum were assessed in September, December, and April (with a loss of 64 students) with the Force Concepts Inventory (FCI), Mechanics Baseline Test (MBT), and a locally developed attitude measure. The observed model indicated that the FCI predicted attitude at time 1 with no other paths between them, that FCI at time 1 predicted MBT at time 1 and time 2, FCI at time 2 predicted MBT at time 3, and MBT at time 1 predicted FCI at time 2. Gender and SAT‐Quantitative scores were predictive only of FCI and MBT at time 1. Results supported an interactive model of conceptual understanding and achievement, with attitude largely irrelevant to the process for this population. © 2000 John Wiley & Sons, Inc.
