This paper describes a framework for learning where learners undergo experimentations with the phenomena at hand according
to progressive and staged goals. Bowling is used as a case study in this paper. The premise for experimentations is that learners
can experience hidden efficacies, including the formation of “bad habits.” A distinction is made between productivity in learning
and performance in terms of learning outcomes. In other words, productivity in learning may not necessarily manifest in successful
performance, hence the term productive failure. To emphasize the need for self-regulation during problem-solving process,
we discuss the movements within the productive–unproductive and success–failure dimensions through three-staged self-regulatory
processes and draw implications to learning and instruction. 相似文献

Research on perceived instrumentality of students’ academic work for attaining life goals has shown to have positive effects on academic achievement and motivation The purpose of the study was to examine the changes in perceived instrumentality over time and to identify how significant others such as parents, teachers and peers affect changes in perceived instrumentality. The variables of gender, prior achievement levels, academic pressure and socioeconomic status, which had significant influences on perceived instrumentality according to previous research, were used as control variables. Longitudinal data were collected for four years of 6908 students and analysed using the Growth Curve Modelling technique. Parents’ and teachers’ academic expectations and their career guidance, and social support from peers were used as predictors for changes in perceived instrumentality. Our results revealed that perceived instrumentality increased over time but in a decelerated pattern. In addition, parents and peers had significant influences on perceived instrumentality and its change, but teachers did not. The results suggest that support from parents and peers helps students to understand and internalise why they have to study hard in school to achieve their future long-term life goals. 相似文献

The study attempted to see if exercise training would alleviate gait asymmetry between nondominant and dominant legs, thus, eliminate the likelihood of slips. The present study provided 18 older adults exercise training for eight weeks and evaluated kinematics and ground reaction forces (GRFs) in both legs. Participants were randomly assigned to balance, weight, or control group. Each group met three times a week for eight weeks. Their pretraining and posttraining kinematic and GRFs data were taken while walking. Data analyses were performed in 2 (Time; pre and post) × 3 (Group; weight, balance, and control) × 2 (Leg; dominant and nondominant) mixed factor repeated measure ANOVA. The results indicated that nondominant legs' heel contact velocity decreased more in comparison to dominant legs' as the knee strength improved. Additionally, factors (PFz and RCOF) contributing to the likelihood of slips were improved after training in nondominant legs. The present study suggested that, after the training, asymmetrical gait or limb patterns could be alleviated, and this outcome may contribute to reductions in the likelihood of slips. 相似文献

This study examined the joint effects of message framing (gain vs. loss) and visual image (image vs. no image) on persuasion as it related to the use of dental floss and the use of sunscreen (N = 252). For both topics, the results revealed a Frame × Image interaction effect on fear. The interaction was such that the presence (vs. absence) of an image produced more fear in the loss-framed conditions. The corresponding results for gain-framed messages were inconsistent. Covariance analyses showed that fear mediated the effect of the interaction on persuasion, whereas dominant cognitive response did not. [Supplementary materials are available for this article.

The innovations of new digital technology as well as the changes in communications policies have made cable operators' triple-play services for consumers possible. In the face of the new type of competition, this study estimates the adoption pattern of triple-play services by cable operators in U.S. local telecommunications markets and discovers factors associated with cable operators' adoptions of triple-play strategies in markets. Probit regression analyses reveal that cable operators having a large video subscriber base are more likely to adopt triple-play strategies in local markets. Apparently, a large video subscriber base provides cable operators with motivation for the adoption of a triple-play strategy in order to hinder video customers' churn to other competitors and to generate additional revenue per customer. 相似文献

Learning happens not only in schools, but also in every context that affords new experiences and opportunities for metacognition. We aim to maximize the different activity-milieux in which learners are engaged in developing their life-long learning dispositions to learn within and across contexts. This paper is a follow up of an earlier published paper in which a framework on interpreting learning as how the self interacts with phenomena and reifications was proposed. Grounded in this learning framework, our research seeks to expand the “within context” learning to “across contexts” learning with evidence from a case study examining a 10-year-old boy's learning process. Through the case study, we will describe the interplay between bowling and schooling and how strategies learned from one context is situated into another drawing upon Ito et al.'s (2010) developmental trajectory of “hanging out-messing around-geeking out” perspectives. The findings show that for learning to be meaningful and authentic for the twenty-first century, it is essential for the learner(s) to be in constant dialectical interactions and relationship with oneself, others, and with the social-cultural artifacts that afford the learning. We conclude with practical implications derived from the study. 相似文献

Most formative assessments rely on the performance status of a student at a particular time point. However, such a method does not provide any information on the propensity of the student to achieve a predetermined target score or whether the student is performing as per the expectations from identical students with the same history of academic achievement. Although such a trend has been proposed via the use of the student growth percentiles (SGPs), most of the work associated with SGPs has focused mainly on teacher and school accountability. In this article, however, we illustrate examples in the use of SGPs and entry growth percentile scores to monitor students' learning progress. Monitoring students' learning trends, evaluated in the context of their SGPs and their propensity to achieve the target score, would likely yield meaningful differential information even for students with the same score at a particular point in time. 相似文献

The main purpose of this study was to investigate the differences between pre-service and in-service teachers in terms of their levels of teaching efficacy and teaching professionalism. In addition, the patterns in predictors of teachers’ teaching efficacy were compared between the two subgroups of this study. Five hundred and seventy-three teachers completed self-administered questionnaires. The in-service teachers were found to have higher efficacy than their counterparts in only one of the six subscales of teaching efficacy, the subscale “Teaching Strategies”. Additionally, the college major specialisation and some domains of professionalism were found to be predictive to both groups. Along with the main results of this study, implications for research and practice are discussed. 相似文献

Ski jumping flight posture was analyzed for achieving large flight distance on the basis of high-speed video images of the initial 40 m part of 120-m ski jumping flight. The time variations of the forward leaning angle and the ski angle of attack were measured from the video images, and the aerodynamic forces were calculated from the kinematic data derived from the images. Some correlations were investigated between the initial-speed corrected flight distance and such parameters as the angles of jumper, the initial transition time and the aerodynamic force coefficients. The result indicated that small body angle of attack was a key for large flight distance in the initial phase of flight because of small drag force, and that the most distinctive fault of beginners was too large body angle of attack and ski angle of attack leading to aerodynamic stall. Too small drag force does not give an optimal condition for large flight distance because the lift force is also too small. The ratio of the lift to the drag was larger than 0.95 for advanced jumpers. 相似文献

This article argues that the social practice of learning (SPL), involving life-long learning, meta-learning, deep reflection,
and dialogue in a community, should be the distinguishing knowledge base of schools in the twenty-first century. This article
also analyses the strategies and challenges of the recent education reforms in Singapore through the lens of an SPL education
paradigm. Although the Singapore government has done much to train teachers, trim syllabi and introduce new ways of teaching
and learning, such as project work, the real challenge is to go beyond the provision of structural changes to the substance
of the epistemological reform. 相似文献
