Based on current theories of multimedia learning, we propose a strategy for learning from animations. Two different experimental studies were conducted in order to evaluate the strategy. In the first study, 22 sixth graders learned from an animation without the strategy while 21 students were encouraged to make use of the proposed strategy during learning; use of the strategy was not monitored. The students who were encouraged to take advantage of the strategy learned significantly more than the students who were not asked to do so. In the second study, three groups of sixth graders were investigated. The first group consisted of 49 students who learned from an animation without the strategy. The second group consisted of 52 students who were encouraged to make use of the strategy during learning; but use of the strategy was not monitored. The third group consisted of 53 students who were also encouraged to make use of the strategy during learning and their use of the strategy was monitored. The results of the second study replicated the findings of the first study. Furthermore, learning was most successful when the students' use of the learning strategy was monitored. 相似文献

The literature on the pedagogical aspects of the photoelectric effect as used in the undergraduate student laboratory shows
that little research has been done in this area. Our current study is an analysis of the instructions in 38, electronically
published laboratory manuals for the photoelectric effect. The analyses were based on history and philosophy of science criteria
that we had developed for evaluating the presentation of the photoelectric effect in introductory, university-physics textbooks.
The results show that writers of laboratory instructions do not pay sufficient attention to the relevant background for the
photoelectric effect. In our study, none of the instructions achieved a score of excellent, only 5% were scored as satisfactory,
and only 7% mentioned the various aspects contained in our criteria. These results for our analysis of laboratory instructions
are significantly less favorable than those achieved for physics textbooks in our previous study. Based on our work, we recommend
that several historical aspects be included in all laboratory instructions for the photoelectric effect. 相似文献

AbstractThere is a kernel of truth in the claim that Western philosophy and practice of education is individualistic; theory in Euro-America tends to prize properties that are internal to a human being, such as her autonomy, rationality, knowledge, pleasure, desires, self-esteem and self-realisation, and education there tends to adopt techniques focused on the individual placed at some distance from others. What is striking about other philosophical–educational traditions in the East and the South is that they are typically much more communitarian. I argue that since geographical terms such as ‘Western’, ‘African’ and the like are best construed as picking out properties that are salient in a region, it is fair to conclude that the Western is individualist and that the African is communitarian. What this means is that if I am correct about a noticeable contrast between philosophies of education typical in the West and in sub-Saharan Africa, and if there are, upon reflection, attractive facets of communitarianism, then those in the West and in societies influenced by it should in some real sense become less Western, in order to take them on. 相似文献

The authors of this paper portray the perspective of Professor Leon Cooper, a theoretical physicist, Nobel laureate, active
researcher, and physics textbook author, on teaching science and on the nature of science (NOS). The views presented emerged
from an interview prepared by the authors and responded to in writing by Professor Cooper. Based on the gathered data and
the subsequent interpretation of it, the authors identified several educational implications and drew the following conclusions:
(a) science should be taught within an historical perspective; (b) textbook authors generally have an empiricist epistemology
which makes their presentation of science difficult to understand; (c) an historical perspective inevitably involves comparing,
contrasting, and scrutinizing different historical accounts of the same events; (d) varying interpretations of observations
do not undermine the objective nature of science; (e) new ideas in physics comprise an imposed vision of the world, and these
ideas are then slowly accepted by the scientific community; (f) the current view in any science is almost always a mixture
of data, hypotheses, theoretical ideas, and conjectures; (g) since experiments are difficult to perform and understand, scientists
rely on their presuppositions to guide the integration of data, theory, and conjectures; (h) inconsistencies in the construction
of theories can facilitate new theoretical ideas; and (i) case studies based on various experiments show that scientists use
intuition which is guided by facts, conjectures, and speculations. 相似文献

There have been many examples of contentious points decisions in boxing. Professional boxing is scored subjectively by judges and referees scoring each round of the contest. We assessed whether the probability of a home win (and therefore home advantage) increased when bouts were decided by points decisions rather than knockouts. Overall, we found that bouts ending in points decisions had a significantly higher proportion of home wins than those decided by a knockout, though this effect varied across time, and controlling for relative quality of boxers was only effective when using more recent data. Focusing on these data, again the probability of a home win was higher with a points decision and this effect was consistent as “relative quality” varied. For equally matched boxers (“relative quality” = 0), expected probability of a home win was 0.57 for knockouts, 0.66 for technical knockouts and 0.74 for points decisions. The results of the present study lend general support to the notion that home advantage is more prevalent in sports that involve subjective decision-making. We suggest that interventions should be designed to inform judges to counter home advantage effects. 相似文献

Rhythmic pumping of light hand-held weights while walking or running has become a popular approach to total body aerobic exercise. The use of handweights (HW) in conjunction with walking and running significantly increases the energy requirement of a given locomotor speed and adds variety to the choice of modes when prescribing exercise regimens (Auble, Schwartz, & Robertson, 1987; Francis & Hoobler, 1986; Graves, Pollock, Montain, Jackson, & O'Keefe, 1987). Handweighted exercise can also be conveniently and accurately prescribed for use with other exercise modalities such as bench stepping (Goss, et al., 1987). Stepping up and down on a bench at varying frequencies while pumping handweights is a low-impact, space efficient form of total body aerobic exercise. However, little is known about the energy cost of this unique exercise modality. Such information is important if handweighted exercise is to be used in conjunction with bench stepping when prescribing both therapeutic and recreational training regimens. The purpose of this investigation, therefore, was to evaluate the energy cost associated with combined bench stepping and rhythmic pumping of light handheld weights. 相似文献
