Children’s use of metacognition in solving everyday problems: An initial study from an Asian context
The aim of this study is to understand the relationship between metacognition and students’ everyday problem solving. Specifically,
we were interested to find out whether regulation of cognition and knowledge of cognition are related to everyday problem
solving and whether students who perform better in the decision-making problem will better differentiate the various components
of metacognition. Two hundred and fifty-four fifth grade students completed a survey. We found evidence to suggest the existence
of two major components of metacognition. Our results also suggest that at a higher level of decision-making, knowledge of
cognition and regulation of cognition were differentiated in their use by participants. 相似文献

Linear direct feed drives are widely used in machine tools, but an abrupt counter force from the secondary part will induce the jerk to the metro frame contacted with the linear motor and cause the vibration of auxiliary devices on it. The jerk-decoupling cartridge (JDC) provides a buffer to reduce such an impact. Design target for such a system includes both the tracking error and the jerk induced to the metro frame. To achieve both targets systematically, this work presents an integrated approach to efficiently determine parameters in the JDC and the position controller of the feed drive. The problem is firstly formulated as a nonlinear constrained optimization problem, which is then converted to a series of projection gradient optimization problems and step searching problems, which are either convex or linear. Thus, fast convergence of parameters are achieved within first several iterations. Through a series of simulation, the effectiveness of proposed methodology is verified. 相似文献

AbstractResearch databases are a significant contributing aspect of modern technology, and, as such, innovation has enhanced learning and research outputs using online databases introduced by authorities in charge of higher education. However, databases have been rarely investigated from the perspective of psychological assessment. Therefore, this research examined databases using structural equation modelling and the Rasch model to explore contributing factors of learning and research in higher education. To measure databases, this research adapted the online database adoption and satisfaction (ODAS) model and analysed the responses of 300 postgraduate students, from a double first class university in Shanghai, collected using a stratified random sample technique. The results of the ODAS model showed that the postgraduate students’ perceived usefulness and ease of use of databases played mediating roles in establishing connections between their computer self-efficacy and intention to use and satisfaction with databases for research and learning. However, the ODAS model also showed that the students’ satisfaction was indirectly explained by their perceived usefulness of databases through ease of use and intention to use. The results of our investigation contribute to a better understanding of the ODAS model and suggest assessment strategies for learning and research through databases for researchers, academicians, and librarians. 相似文献

Whilst much research has been conducted on teacher feedback in various teaching and learning contexts, little is known about how teachers give feedback on student oral presentations to enhance students’ oral communicative skills in second-language (L2) education. Drawing on data from semi-structured interviews, this case study investigated the methods used by an experienced Chinese teacher of English as a Foreign Language to provide feedback on student oral presentation tasks. Data analysis revealed that the teacher gave oral comments mainly on pronunciation, content and logical thinking, and focused on PowerPoint design in his written commentary. The analysis also revealed that the teacher used the specific pattern of ‘praise-criticism-suggestion’ to comment on the students’ oral presentations. Relevant pedagogical implications for L2 teacher feedback practices and teacher-education programmes are discussed in the paper. 相似文献

Despite the prevalence and significance of e-learning in education, there is a dearth of published instruments for educational researchers and practitioners that measure users’ acceptance of e-learning. To meet this need, Teo (2010) developed the E-learning Acceptance Measure (ElAM). The main objective of this paper is to validate the ElAM (Teo, 2010) across two cultures, one is from a European country: England, and the other from Asia: Lebanon. A total sample of 461 university students from two private universities in Lebanon (n?=?209) and one university in England (n?=?252) participated in this study. Using confirmatory factor analyses, our findings revealed that the original 3-factor solution for ElAM (Teo, 2010) was supported and found to be adequate for the British sample, whereas the results revealed a bad fit for the Lebanese sample. Despite the differences, the ElAM was found to possess an acceptable level of internal consistency and item reliability for the pooled sample. Theoretical and practical implications are discussed at the end of the paper. 相似文献
