This study investigated the value of using a scaffolded critique framework to promote two different types of writing—argumentative writing and explanatory writing—with different purposes within an argument-based inquiry approach known as the Science Writing Heuristic (SWH) approach. A quasi-experimental design with sixth and seventh grade students taught by two teachers was used. A total of 170 students participated in the study, with 87 in the control group (four classes) and 83 in the treatment group (four classes). All students used the SWH templates as an argumentative writing to guide their written work and completed these templates during the SWH investigations of each unit. After completing the SWH investigations, both groups of students were asked to complete the summary writing task as an explanatory writing at the end of each unit. All students’ writing samples were scored using analytical frameworks developed for the study. The results indicated that the treatment group performed significantly better on the explanatory writing task than the control group. In addition, the results of the partial correlation suggested that there is a very strong significantly positive relationship between the argumentative writing and the explanatory writing. 相似文献

Analysis of academic administrators’ attitudes: annual evaluations and factors that improve teaching
Brian D. Cherry Nathan Grasse Dale Kapla Brad Hamel 《Journal of Higher Education Policy & Management》2017,39(3):296-306
This article examines academic administrators’ attitudes towards the academic evaluation process in the US and those factors that are utilised to improve teaching. We use path regressions to examine satisfaction with evaluation procedures, as well as the direct and indirect effects of these factors on perceptions of whether the evaluation process facilitates quality instruction. With increased pressure for accountability being placed on higher education, it is important to ensure that we are meeting both public and academic expectations. The evaluation process is an important tool to ensure the university’s goals and values are articulated and that academics can be successful in their individual career paths. The problem is most research finds flaws with the current method of evaluation, and academics and academic administrators are sceptical about the process and results. We find there are environmental factors that influence academic administrators’ perceptions of academic evaluations and the ability to improve classroom instruction. 相似文献

This article examines college student disengagement from sports, presents a multidimensional concept of athletic identity, and introduces a new measure intended to assist college counselors in their work with disengaged athletes. The Multidimensional Athletic Identity and Engagement Scale (MAIES) is introduced (Cronbach alpha .98, with subscale alphas between .78 and .96), and the results of exploratory and confirmatory factor analyses and convergent and divergent validity with 250 college student participants are presented. Using case examples, the authors discuss how counselors may use the MAIES in their work with students. Limitations of the study and suggestions for future research are discussed. 相似文献

A general input-to-state stability (ISS)-type small-gain result is presented. It specializes to a small-gain theorem for ISS operators, and it also recovers the classical statement for ISS systems in state-space form. In addition, we highlight applications to incrementally stable systems, detectable systems, and to interconnections of stable systems. 相似文献

In recent years it has become clear that a firm's competitive position is significantly influenced by its capacity to innovate. This paper explores the hypothesis that if there are factors operating at the regional level which inhibit this capacity, then firms located in particular regions may suffer. One such factor might be a lack of centralized scientific services. Regions under-represented in terms of a viable scientific infrastructure may find difficulty in attrating new science-based firms, and firms already in the region may find themselves at a comparative disavantage compared with firms located elsewhere. Social forces of this kind might be playing an important part in enhancing the social and economic problems of underdeveloped regions. 相似文献

Students engaged in problem-based learning (PBL) units solve ill-structured problems in small groups, and then present arguments
in support of their solution. However, middle school students often struggle developing evidence-based arguments (Krajcik
et al., J Learn Sci 7:313–350, 1998). Using a mixed method design, the researchers examined the use of computer-based argumentation scaffolds, called the Connection Log, to help middle school students build evidence-based arguments. Specifically we investigated (a) the impact of computer-based
argumentation scaffolds on middle school students’ construction of evidence-based arguments during a PBL unit, and (b) scaffold
use among members of two small groups purposefully chosen for case studies. Data sources included a test of argument evaluation
ability, persuasive presentation rating scores, informal observations, videotaped class sessions, and retrospective interviews.
Findings included a significant simple main effect on argument evaluation ability among lower-achieving students, and use
of the scaffolds by the small groups to communicate and keep organized. 相似文献

This study is the first to inquire about the factors that influence people’s willingness to allow professional photojournalists to tell their stories through the medium of the photo essay. Guided by Self-Disclosure Theory, in-depth interviews were conducted with the subjects of 15 peer-judged award-winning photo essays. These were drawn from the multiple picture categories of the National Press Photographers Association (NPPA) Monthly Clip Contest, the annual NPPA Best of Photojournalism Contest, and the annual World Press Photo Contest between 2013 and 2017. The topics of the photo essays were sensitive in nature. Analysis reveals support and appreciation amongst photo-essay subjects for the profession of photojournalism. Motivations derived from the sensitivity and professionalism with which each interviewee was initially approached, a need to tell a different side of the story, a desire to inspire others or invoke change, and the memory-keeping and permanence afforded through published professional photojournalism. 相似文献

The purpose of this study was to evaluate the effects of whole-body vibration (WBV) on the muscle recruitment of selected upper and lower body muscles during the baseball swing. Participants were recreationally trained males (n = 16, 22 +/- 2 years, 181.4 +/- 7.4 cm, 84.7 +/- 9.0 kg), with previous baseball experience. Subjects participated in three randomized sessions on separate days, consisting of three sets of five swings offa hitting tee. Exercises (upper and lower body dynamic and static movements) with or without WBVexposure were performed between swing sets. During each swing, the gastrocnemius, biceps femoris, gluteus maximus, pectoralis major, latissimus dorsi, and triceps brachii were evaluated for electromyographic (EMG) activity. EMG values were normalized to EMG measured during maximal voluntary isometric contraction. Statistical analysis revealed no significant differences in EMG activity across the three treatments. In addition, the results displayed a specific muscle recruitment order during the swing, starting with the lower body followed by the upper body muscles. This study was the first to report the recruitment order during the baseball swing. Although acute exposure to WBV did not significantly alter the muscle recruitment, these results may prove useful for practitioners looking to enhance baseball swing performance. 相似文献

This paper examines a controversial research programme aimed at the production of transgenic cows in New Zealand. It emphasizes the contested representation of the research, in its promotion, in its governance, and in the opposition sparked amongst environmentallanti-genetic modification groups and within the Māori community. The paper contends that the case of New Zealand's genetically modified cows certainly reveals some unique features of the prevailing economic, geographical and cultural context, but nonetheless has salience for the broader understanding of the promotion, public reception and governance of genetic modification. 相似文献
