Comprehensive schoolwide initiatives like integrated multitiered systems of support (I-MTSS) and universal design for learning (UDL) present opportunities for large-scale impact on improving teacher instructional practices and, therefore, student outcomes. Specifically, implementing I-MTSS and UDL concurrently presents an opportunity to enhance and improve universal instruction for all students. This mixed-methods study explored current Tier 1 practices in elementary schools across the United States. Findings revealed that I-MTSS and UDL are perceived as being implemented concurrently. In addition, school personnel identified specific barriers to implementation. 相似文献

Caffeine and coffee are widely used among active individuals to enhance performance. The purpose of the current study was to compare the effects of acute coffee (COF) and caffeine anhydrous (CAF) intake on strength and sprint performance. Fifty-four resistance-trained males completed strength testing, consisting of one-rep max (1RM) and repetitions to fatigue (RTF) at 80% of 1RM for leg press (LP) and bench press (BP). Participants then completed five, 10-second cycle ergometer sprints separated by one minute of rest. Peak power (PP) and total work (TW) were recorded for each sprint. At least 48 hours later, participants returned and ingested a beverage containing CAF (300?mg flat dose; yielding 3–5?mg/kg bodyweight), COF (8.9?g; 303?mg caffeine), or placebo (PLA; 3.8?g non-caloric flavouring) 30 minutes before testing. LP 1RM was improved more by COF than CAF (p?=?.04), but not PLA (p?=?.99). Significant interactions were not observed for BP 1RM, BP RTF, or LP RTF (p?>?.05). There were no sprint?×?treatment interactions for PP or TW (p?>?.05). 95% confidence intervals revealed a significant improvement in sprint 1 TW for CAF, but not COF or PLA. For PLA, significant reductions were observed in sprint 4 PP, sprint 2 TW, sprint 4 TW, and average TW; significant reductions were not observed with CAF or COF. Neither COF nor CAF improved strength outcomes more than PLA, while both groups attenuated sprint power reductions to a similar degree. Coffee and caffeine anhydrous may be considered suitable pre-exercise caffeine sources for high-intensity exercise. 相似文献

In this article, we explore how youth audiences evaluate the quality of youth-produced films. Our interest stems from a dearth of ways to measure the quality of what youth produce in artistic production processes. As a result, making art in formal learning settings devolves into either romanticized creativity or instrumental work to improve skills in core content areas. We conducted focus groups with 38 youth participants where they viewed four different films produced by the same youth media arts organization that works with young people to produce short-form, autobiographical documentaries. We found that youth focused their evaluations on identifying the films' genre and content and on assessing how well the filmmakers' creative decisions fit with identifications of genre and content. Evaluations were mediated by audiences' expectations and seemed to inform judgments of quality and creativity. We hope that our work can inform the design of formal learning spaces where young people are producing narrative art. 相似文献

Recent research has shown that exposure to entertainment media depicting moral beauty may not only influence viewers' affective responses, but also lead to altruistic behavior. Although the process has been tied to a set of feelings commonly referred to as elevation, the mechanisms by which the effects take place have not been examined. This experiment (N = 107) showed that participants who watched a clip portraying moral beauty were more likely to help with an unrelated volunteer task after viewing than those who watched a non-meaningful clip. The effect of the clip was mediated by the degree to which the clip produced mixed affective response in participants. Although the clip portraying moral beauty led to increased empathy with the character and increased feelings of elevation, neither of these predicted helping behavior after controlling for clip content. Helping behavior also increased when the help recipient was less similar to the participants (age, race, and university affiliation). 相似文献

Quality and Qualms in the Marking of University Assignments by Sessional Staff: An Exploratory Study 总被引:3,自引:0,他引:3
The higher education sector is increasingly reliant upon casual (‘sessional’) staff for teaching and marking purposes. While
this practice has been little examined in the past, over the last few years increasing attention has been paid to the quality
of marking, mainly because students and academic staff alike are becoming increasingly likely to question examples of poor
practice. Hence, many universities in Australia are now attempting to introduce stricter procedures relating to marking. Despite
current concerns, there is little published research on marking practices in Australian universities. This paper adds to the
body of knowledge by reporting on two pieces of empirical research into the use of casual markers. A project at Charles Sturt
University comprised focus groups of, respectively, students, lecturers and markers, and a survey of distance education students.
Research at the University of South Australia focused on pedagogical issues relating to marking, comparing the approaches
of permanent lecturing staff with those of sessional markers. The results of these projects provide a useful insight into
areas of current concern to university staff and management. 相似文献

Teachers have a central role in developing new learning models in schools. This paper describes a study that explored teachers’ confidence and competence in using Information and Communication Technologies (ICT) as they participated in an ICT development project conducted by an Australian education system in 12 primary schools. The project aimed to develop ICT integrated teaching practices by providing in‐class equipment and teacher professional development in ICT use, curriculum development and teaching strategies. The study used qualitative data from teacher records of Professional Development and Action Learning to identify three of four stages proposed to describe teachers’ ICT learning. Teachers moved from gaining basic ICT skills, to conducting ICT‐focused lessons and eventually appropriate ICT integration. Teachers who progressed to the third stage were able to exploit additional learning opportunities and begin to make fundamental changes to their pedagogy, but needed more time to reach the final stage of challenging existing pedagogical structures. 相似文献

Numerous national reports have identified the importance of significantly improving pathways that begin with Latinx students enrolling in 2-year institutions and ultimately completing baccalaureate degrees in STEM fields at 4-year institutions. Many programs using multiple interventions have been designed, implemented, and studied to achieve this goal. To synthesize what has been learned from studies of these programs, this article presents a systematic review of published studies of programs designed to support Latinx student success in 2-year institutions and successful transfer to 4-year institutions, particularly for STEM majors. A total of 49 quantitative, 9 qualitative, and 16 mixed-methods studies published as reports, articles, or dissertations since 1980 were identified that met the criteria for the review. Studies covered a wide range of interventions, including mentoring, counseling, advising, study groups, tutoring, scholarships, orientations, career services, undergraduate research, articulation agreements, and transfer programs. Individually, these studies report positive influences on student success outcomes, including 2- and 4-year graduation, transfer to a 4-year institution, retention, and success in individual courses. However, the number of qualifying studies was surprisingly small, considering the importance of improving success of Latinx students and the length of time during which the problem has been repeatedly emphasized. Few interventions have been undertaken from explicitly assets-based perspectives or theoretical frameworks. The lack of explicit frameworks underlying interventions—combined with a sole/primary focus on students—suggests many interventions were approached from a deficit-based perspective. Further, the study found no pattern of replication studies that might confirm effectiveness of potentially promising interventions. Based on our analysis of evaluations presented in the studies, it does not appear that the research community has developed agreed-upon methods to evaluate commonly agreed-upon outcomes. Finally, no intervention has been sufficiently supported that widespread implementation could be recommended. 相似文献

Zusammenfassung.
Die Beweisentwicklungsumgebung -Mkrpsoll
Mathematiker bei einer ihrer
Hauptt?tigkeiten, n?mlich dem Beweisen mathematischer Theoreme
unterstützen. Diese Unterstützung mu? so komfortabel sein,
da? die
rechnergestützte Suche nach formalen Beweisen leichter und insbesondere
weniger aufwendig ist, als ohne das System. Dazu mu? die verwendete
Objektsprache ausdrucksstark sein, man mu? die M?glichkeit haben, abstrakt
über Beweispl?ne zu reden, die gefundenen Beweise müssen in einer am
Menschen orientierte Form pr?sentiert werden und vor allem mu? eine
effiziente Unterstützung beim Füllen von Beweislücken zur Verfügung
stehen. Das im folgenden vorgestellte $\Omega$-Mkrp-System ist
der Versuch einer
Synthese der Ans?tze des vollautomatischen, des interaktiven und des
planbasierten Beweisens. Dieser Artikel soll eine übersicht über unsere
Arbeit an diesem System geben.
