This case study looked at how an assessment strategy designed for an online learning environment can support teachers’ professional development. More specifically, we intended to evaluate how a particular online assessment design can help the participating in-service teachers to recognize the added value of formative assessment, and promote their own use of formative assessment in their professional classroom practices. The presented assessment design consists of a combination of different, non-standard assessment methods in an online environment. We analysed data from 494 questionnaires, the participants’ critical reflections about their learning and the participants’ produced artefacts. The findings illustrate the participants’ recognition of the formative character of the proposed assessment design, reflected not only by the high scores reported in seven of the eight themes explored, but also from the qualitative analysis of the participants’ reflections and artefacts. Suggestions are offered for the improvement of the proposed assessment design, so as to better promote the formative character of assessment. In particular, implications for the development of formative assessment in online professional development are discussed taking into account its potential to promote the participants’ self-regulatory learning processes. 相似文献

ABSTRACTOne aim of environmental education is to encourage different ways of generating meanings of, valuing, conceiving, and contextualizing “nature.” The field of aesthetics provides an affective basis for interpreting our perceptions of environments and relations with other more-than-human beings. This critical essay examines some of the key concepts about hermeneutics and phenomenology introduced by philosophers such as Kant, Dufrenne, Bachelard, Merleau-Ponty, Gadamer, and Quintás and then indicates some methodological implications. Our Freirean purpose is to advance how understandings of the nature of the aesthetic experience of nature might inform different research framings, critical curriculum inquiry, and eco-pedagogical explorations of being in, becoming and relating with nature. 相似文献

In the last years, science courses in higher education (HE) have been facing some problems, namely the lack of students’ motivation, the number of students’ failures and drop outs, particular in physics courses. The most probable reason, which has been mentioned in current science education research in HE, is that the level of interaction between teachers and learners in formal instructional settings is very low. In this paper, we describe changes that were introduced in lectures towards the promotion of active learning and analyse its effects in the classroom environment. The introduction of conceptual questions and peer instruction seems to motivate students in the class and help them engage in the learning process. These strategies have been used in the first year of an introductory physics course for engineering students in two different Portuguese HE institutions. The data were collected through questionnaires and student interviews. 相似文献

Abstract This article uses a critique of modernity to examine the perceived relationship between global citizenship education (GCE) and digital democracy (DD). We review critiques of citizenship education in the global imperative and of the relationship of technology to democratic engagement. An analogy expresses the problematic way that GCE and DD are both mutually compatible and complicit in ethical global justice issues. We end with a suggestion of a pedagogical framework through which educators can engage with an ethical approach to GCE and DD. 相似文献

Abstract The objective of this study was to identify the methodological approaches employed in a sample of Brazilian distance education scientific literature and compare with similar publications in the United States. Brazilian sample articles (N = 983) published in several journals and meetings were compared with a sample of articles published in The American Journal of Distance Education (AJDE) from 1987 to 2006. A categorization system based on Gall, Gall, and Borg (2006) and Lee, Driscoll, and Nelson (2007) was used. The methodological approach employed in the Brazilian sample was predominantly qualitative, and this feature remained largely unchanged over the past seven years. The predominant research method continues to be exploratory, followed by case studies. Of note, the most frequent research topic in AJDE articles was evaluation, contrasting with the predominant topic of management in Brazilian publications. 相似文献

Abstract We assessed the agreement between maximal oxygen consumption ([Vdot]O2max) measured directly when performing the 20-m shuttle run test and estimated [Vdot]O2max from five different equations (i.e. Barnett, equations a and b; Léger; Matsuzaka; and Ruiz) in youths. The 20-m shuttle run test was performed by 26 girls (mean age 14.6 years, s = 1.5; body mass 57.2 kg, s = 8.9; height 1.60 m, s = 0.06) and 22 boys (age 15.0 years, s = 1.6; body mass 63.5 kg, s = 11.5; height 1.70 m, s = 0.01). The participants wore a portable gas analyser (K4b2, Cosmed) to measure [Vdot]O2 during the test. All the equations significantly underestimated directly measured [Vdot]O2max, except Barnett's (b) equation. The mean difference ranged from 1.3 ml · kg?1 · min?1 (Barnett (b)) to 5.5 ml · kg?1 · min?1 (Léger). The standard error of the estimate ranged from 5.3 ml · kg?1 · min?1 (Ruiz) to 6.5 ml · kg?1 · min?1 (Léger), and the percentage error ranged from 21.2% (Ruiz) to 38.3% (Léger). The accuracy of the equations available to estimate [Vdot]O2max from the 20-m shuttle run test is questionable at the individual level. Furthermore, special attention should be paid when comparisons are made between studies (e.g. population-based studies) using different equations. The results of the present study suggest that Barnett's (b) equation provides the closest agreement with directly measured [Vdot]O2max (cardiorespiratory fitness) in youth. 相似文献

Abstract In this study we examined the timing of optical information pick-up in basketball jump shooting using an intermittent viewing technique. We expected shooters to prefer to look at the basket as late as possible under the shooting style used. Seven experts with a high shooting style and five experts with a low shooting style took 50 jump shots while wearing liquid-crystal glasses that opened and closed at pre-set intervals. In principle, under this constraint, the participants could control when they saw the basket by actively modulating the timing of their movements. Analyses of the phasing of the movements relative to the events defined on the glasses revealed that low-style shooters preferred to see the basket just before the ball passed their line of sight, whereas high-style shooters tended to view the basket from underneath the ball after it passed their line of sight. Thus, most shooters preferred to pick up optical information as late as possible given the adopted shooting style. We conclude that, in dynamic far aiming tasks such as basketball jump shooting, late pick-up of optical information is critical for the successful guidance of movements. 相似文献

Abstract In this study, we evaluated the peak torque, functional torque ratios, and torque curve profile of the shoulder rotators in overhead athletes with impingement symptoms so as to examine possible alterations in response to sports training and shoulder pain. Twenty-one overhead athletes with impingement symptoms were compared with 25 overhead athletes and 21 non-athletes, none of whom were symptomatic for impingement. The participants performed five maximal isokinetic concentric and eccentric contractions of medial and lateral shoulder rotations at 1.57 rad · s?1 and 3.14 rad · s?1. Isokinetic peak torque was used to calculate the eccentric lateral rotation-to-concentric medial rotation and the eccentric medial rotation-to-concentric lateral rotation ratios. An analysis of the torque curve profiles was also carried out. The eccentric lateral rotation-to-concentric medial rotation torque ratio of asymptomatic athletes was lower than that of non-athletes at both test velocities. The concentric medial rotation isokinetic peak torque of the asymptomatic athletes, at 3.14 rad · s?1, was greater than that of the non-athletes, and the peak appeared to occur earlier in the movement for athletes than non-athletes. These findings suggest that there may be adaptations to shoulder function in response to throwing practice. The eccentric medial rotation-to-concentric lateral rotation torque ratio was altered neither by the practice of university-level overhead sports nor impingement symptoms. 相似文献

Abstract Twelve participants ran (9 km · h?1) to test two types of running shoes: replica and original shoes. Ground reaction force, plantar pressure and electromyographic activity were recorded. The shoes were tested randomly and on different days. Comparisons between the two experimental conditions were made by analysis of variance (ANOVA) test (P ≤ 0.05). The time to first peak, loading rate of the first peak and impulse of the first 75 ms of stance were significantly different between the shoes (P ≤ 0.05), revealing an increase of impact forces for the replica shoes. The peak plantar pressure values were significantly higher (P ≤ 0.05) when wearing replica shoes. During running, the contact area was significantly smaller (P ≤ 0.05) for the replica shoe. The electromyographic activity of the analysed muscles did not show changes between the two shoes in running. These findings suggest that the use of replica running shoes can increase the external load applied to the human body, but may not change the muscle activity pattern during locomotion. This new mechanical situation may increase the risk of injuries in these movements. 相似文献
