In this paper we explore the relationship between learning gains, measured through pre‐assessment and post‐assessment, and engagement in scientific argumentation. In order to do so, this paper examines group discourse and individual learning during the implementation of NASA Classroom of the Future’s BioBLAST!® (BB) software program in a high school biology classroom. We found that the argumentative structures, the quality of these structures, and the identities that students take on during collaborative group work are critical in influencing student learning and achievement in science. We provide recommendations for instructors implementing argumentation in their science classrooms, and provide suggestions for the development of future research in this area. 相似文献

The most frequently occurring contact events in rugby union are the tackle and ruck. The ability repeatedly to engage and win the tackle and ruck has been associated with team success. To win the tackle and ruck, players have to perform specific techniques. These techniques have not been studied at the highest level of rugby union. Therefore, the purpose of this study was to identify technical determinants of tackle and ruck performance at the highest level of rugby union. A total of 4479 tackle and 2914 ruck events were coded for the Six Nations and Championship competitions. Relative risk ratio (RR), the ratio of the probability of an outcome occurring when a characteristic was observed (versus the non-observed characteristic), was determined using multinomial logistic regression. Executing front-on tackles reduced the likelihood of offloads and tackle breaks in both competitions (Six Nations RR 3.0 Behind tackle, 95% confidence interval [95% CI]: 1.9–4.6, effect size [ES] = large, P < 0.001); Championship RR 2.9 Jersey tackle, 95% CI: 1.3–6.4, ES = moderate, P = 0.01). Fending during contact increased the chances of offloading and breaking the tackle in both competitions (Six Nations RR 4.5 Strong, 95% CI: 2.2–9.2, ES = large, P = P < 0.001; Championship RR 5.1 Moderate, 95% CI: 3.5–7.4, ES = large, P < 0.001). For the ruck, actively placing the ball increased the probability of maintaining possession (Six Nations RR 2.2, 95% CI: 1.1–4.3, ES = moderate, P = 0.03); Championship RR 4.0, 95% CI: 1.3–11.8, ES = large, P = 0.01). The techniques identified in this study should be incorporated and emphasised during training to prepare players for competition. Furthermore, these techniques need to be added to coaching manuals for the tackle and ruck. 相似文献

A questionnaire regarding attitudes toward science and scientific knowledge (Yager & Yager, 1985b) was administered to 143 intellectually gifted (IQ > 130) and intellectually average third-, seventh-, and eleventh-grade students. Measures of internal reliability on four attitude subscales and a content knowledge subscale are reported. Three-way ANOVAs comparing grade, sex, and ability revealed significant differences between average and gifted students in attitudes toward being a scientist, usefulness of science, and, as might be expected, in knowledge of science. Similarly, there were significant differences between grades on attitudes toward teachers and toward science classes, with the most favorable attitudes expressed in third grade, next most favorable in eleventh grade, and clearly more negative attitudes expressed by students in seventh grade. There also was a significant interaction between grade level and ability regarding attitudes toward science classes. In contrast to what might be expected from reported differences between males and females in attitudes toward science, gender as a separate variable did not have a significant main effect in any of the comparisons. 相似文献

This study profiles gender differences in instrumental performance self-efficacy perceptions of high school students (N?=?87) over the course of a three-day orchestra festival in which students competed against one another for rank-based seating and then rehearsed and performed as a group. Reported self-beliefs rose significantly for the sample over the course of the festival. Self-efficacy beliefs of females were significantly lower than those of males before the seating audition and first rehearsal, but were no longer different by the midpoint of the festival. Survey free-response data were coded according to Bandura's (1997) four sources of self-efficacy. A 52% drop in the frequency of student comments regarding competitive comparison appeared at the same point in which female self-efficacy beliefs were no longer different from those of males. Results support past research to suggest that males and females may respond differently to rank-based competition versus social support. 相似文献

Using visual strategies simultaneously to support students with learning disabilities in mathematics
We provide insight into how multiple visual strategies can be used simultaneously to increase access to and success with challenging mathematics at the secondary level for students with learning disabilities. Drawing on a teaching philosophy based on recognising student strengths and needs, we argue the potential benefits of using visual strategies during instruction and intervention to best meet student needs. Examples from our work with a high school student with a learning disability are presented to provide insight into how visual strategies can increase understanding and success with mathematics as it becomes more abstract at the secondary level. We urge practitioners and researchers to explore the benefits of incorporating simultaneous visual strategies into secondary mathematics learning. 相似文献

Home-based therapy has become an ongoing trend within the mental health field. This transcendental phenomenologically designed study explored the lived experiences of clinical mental health counseling internship students (N=8) who provided home-based therapy as their primary method of gaining required clinical experience for the completion of their master’s degree. The overall personal and professional development of the students providing therapy in this setting was explored. Insights of the internship students regarding their experiences and challenges in providing home-based therapy were revealed. Recommendations based on the experiences of the students providing home-based therapy were offered. Implications to students, counselor educators, and supervisors have also been provided.

It is necessary to study the rugby tackle as it is associated with successful performance outcomes and is responsible for the majority of contact injuries. A novel collision sport simulator was developed to study tackle performance. The main aim of this validation study was to assess tackle technique performance between two different conditions: simulator versus a standardised one-on-one tackle drill previously used to assess technique. Tackling proficiency was assessed using a list of technical criteria. Mean scores, standard deviations and Cohen’s d effect sizes were calculated. Mean overall score for dynamic i.e. running simulator tackles was 7.78 (95%CI 7.58–7.99) (out of 9) or 87% (standard deviation or SD±8.94), and mean overall score for dynamic “live” tackles was 7.85 (95%CI 7.57–8.13) (out of 9) or 87% (SD±9.60) (effect size = 0.08; trivial; p > 0.05). Mean overall score for static i.e. standing simulator tackles was 7.45 (95%CI 7.20–7.69) (out of 9) or 83% (SD±10.71), and mean overall score for static “live” tackles was 8.05 (95%CI 7.83–8.27) (out of 9) or 89% (SD±7.53) (effect size = 0.72; moderate; p < 0.001). The simulator replicates dynamic tackle technique comparable to real-life tackle drills. It may be used for research analysing various aspects of the tackle in rugby and other contact sports. 相似文献

Male and female rats were weaned at 14 days of age and raised in social isolation or with three other animals. At maturity the male isolates displayed less male sexual behavior than the socially reared Ss. Female isolates, after ovariectomy and injection with androgen, exhibited much less male sexual behavior than control females similarly tested. After being brought into estrus by injections of estrogen and progesterone, the female sexual behavior of female social and isolate Ss did not differ. Data were interpreted as indicating that social isolation during development deprives rats of critical experiences necessary for development of appropriate responses to social stimuli eliciting male copulatory behavior in both sexes. 相似文献

The research examined effects of notetaking instruction on elementary-aged students’ abilities to recall science information
and their notetaking behaviors. Classes of eight to nine years old third grade students were randomly assigned to three treatment
conditions: strategic notetaking, partial strategic notetaking, and control, for four training sessions. The effects of the
notetaking instruction were measured by their performances on a test about science information, a long-term free recall of
the information, and the number of information units recalled with or without cues. Students’ prior science achievement was
used to group students into two levels (high vs. low) and functioned as another independent variable in analysis. Results
indicated significant treatment effect in favor of the strategy notetaking instruction groups on cued and non-cued recall
of the information units. Students with higher prior achievement in science performed better on cued recall and long-term
free recall of information. The results suggest that students as young as those in third grade classes can be instructed to
develop notetaking ability that promotes their learning. 相似文献
