Students who demonstrate persistent mathematics difficulties and whose performance is severely below grade level require intensive intervention. Intensive intervention is an individualized approach to instruction that is more demanding and concentrated than Tier 2 intervention efforts. We present the elements of intensive intervention that teachers should consider when planning for, implementing, and monitoring intensive intervention in mathematics. Each of these elements is based on evidence from validated interventions. We also highlight strategies for intensifying instruction. We provide two examples of intensive intervention, one of which launches from a Tier 2 intervention platform and the other which is completely generated by a teacher. We conclude with considerations for intensive intervention in mathematics.  相似文献   

The governmentality of childhood obesity: Coca-Cola,public health and primary schools     

Darren Powell  Michael Gard 《Discourse: Studies in the Cultural Politics of Education》2015,36(6):854-867

In this paper, we examine the emergence of what might seem an unexpected policy outcome – a large multinational corporation, frequently blamed for exacerbating childhood obesity, operating as an officially sanctioned driver of anti-obesity initiatives in primary schools across the globe. We draw on Foucault's notion of governmentality to examine the pedagogical work of two international programmes devised and funded by Coca-Cola. We demonstrate how these programmes work simultaneously as marketing campaigns and as governmental strategies to position children as responsible for their own health, conflate (ill)health with body weight and strategically employ the concept of energy balance. We argue that these programmes not only act to unite the interests of corporations, governments and schools, but also seek to use schools to reshape the very ideas of health and a ‘healthy life’. We conclude by considering two sets of ethical and political issues that come sharply as corporations like Coca-Cola continue to exploit the policy space created by the ‘obesity epidemic’.  相似文献   

Perceptions of junior doctors and undergraduate medical students as anatomy teachers: Investigating distance along the near‐peer teaching spectrum          下载免费PDF全文

Near‐peer teaching involves more experienced students acting as tutors and has been widely used in anatomy education. This approach has many advantages for the learner due to the social and cognitive congruence they share with the teacher, however, the influence of distance between the teacher and learner on these congruences has yet to be explored. The aim of this study was to compare the attitudes and perceptions of the student learner towards neuroanatomy review sessions taught by either a senior medical student or a junior doctor. The students were randomly assigned to an allocated tutor. All tutors used standardized material and had access to identical resources. The type of allocated tutor was swapped between the two teaching sessions and 99 student feedback forms were collected in total. The rating for the overall quality of the teaching session was not significantly different between the junior doctors and senior medical students (P = 0.11). However, criteria closely relating to social and cognitive congruence such as “enjoyment of the session,” “delivery of the teaching,” and “was it a good use of time” were all rated significantly higher for the senior medical students (P < 0.05). The results of this study suggest that small increases in distance along the near‐peer teaching spectrum have an impact upon the student's perception of their learning experience. While all teachers were suitable role models it appears that junior doctors are too far removed from their own undergraduate experiences to share congruences with pre‐clinical medical students.

“It’s not them,it’s me”: competing discourses in one aspiring teacher’s talk     

Mary Louise Gomez  James R. Carlson  Jennifer Foubert  Shameka N. Powell 《Teaching Education》2014,25(3):334-347

In this paper, we deploy M.M. Bakhtin’s notions about how language works to understand aspiring teachers’ struggles about the intersecting roles race, class, gender, language background, and sexual orientation play in students’ school lives and learning. Through life-history interviews and document analysis, we investigated the authoritative and internally persuasive discourses one aspiring teacher brought with her and took from a 15-week long course on a predominantly White Midwestern public university campus. Ideas she encountered in the course and its required tutoring component challenged her thinking about how various facets of people’s lives (such as those we list above) and the contexts in which they live, work and are schooled, affect how they are perceived, what they know, and can do.  相似文献   

Environmental education program evaluation in the new millennium: what do we measure and what have we learned?     

Marc J. Stern  Robert B. Powell  Dawn Hill 《Environmental Education Research》2014,20(5):581-611

We conducted a systematic literature review of peer-reviewed research studies published between 1999 and 2010 that empirically evaluated the outcomes of environmental education (EE) programs for youth (ages 18 and younger) in an attempt to address the following objectives: (1) to seek reported empirical evidence for what works (or does not) in EE programming and (2) to uncover lessons regarding promising approaches for future EE initiatives and their evaluation. While the review generally supports consensus-based best practices, such as those published in the North American Association for Environmental Education’s Guidelines for Excellence, we also identified additional themes that may drive positive outcomes, including the provision of holistic experiences and the characteristics and delivery styles of environmental educators. Overall, the evidence in support of these themes contained in the 66 articles reviewed is mostly circumstantial. Few studies attempted to empirically isolate the characteristics of programs responsible for measured outcomes. We discuss general trends in research design and the associated implications for future research and EE programming.  相似文献   

The effect of playing formation on high-intensity running and technical profiles in English FA Premier League soccer matches

The aim of this study was to examine the effect of playing formation on high-intensity running and technical performance during elite soccer matches. Twenty English FA Premier League games were analysed using a multiple-camera computerized tracking system (n = 153 players). Overall ball possession did not differ (P < 0.05) between 4-4-2, 4-3-3 and 4-5-1 formations (50%, s = 7 vs. 49%, s = 8 vs. 44%, s = 6). No differences were observed in high-intensity running between 4-4-2, 4-3-3 and 4-5-1 formations. Compared with 4-4-2 and 4-3-3 formations, players in a 4-5-1 formation performed less very high-intensity running when their team was in possession (312 m, s = 196 vs. 433 m, s = 261 vs. 410 m, s = 270; P 5 0.05) but more when their team was not in possession (547 m, s = 217 vs. 461 m, s = 156 vs. 459 m, s = 169; P < 0.05). Attackers in a 4-3-3 performed ~30% more (P < 0.05) high-intensity running than attackers in 4-4-2 and 4-5-1 formations. However, the fraction of successful passes was highest in a 4-4-2 (P < 0.05) compared with 4-3-3 and 4-5-1 formations. The results suggest that playing formation does not influence the overall activity profiles of players, except for attackers, but impacts on very high-intensity running activity with and without ball possession and some technical elements of performance.  相似文献

The residues of learning: Autobiographical accounts by graduates of the impact of higher education     

J. P. Powell 《Higher Education》1985,14(2):127-147

Earlier work on the enduring effects of education is reviewed and then data are presented from 22 autobiographical accounts written by graduates. Content analysis showed that most importance was attached to the learning of high-level intellectual skills and to attitudes and values of personal and professional significance. The implications of these findings for curricula and teaching methods in higher education are then discussed before considering the strengths and weaknesses of life history material as a research tool. It is concluded that written accounts combined with interviews offer a promising method for investigating the long-term impact of higher education.  相似文献   

Learning opportunities from group discussions: warrants become the objects of debate     

Keith Weber  Carolyn Maher  Arthur Powell  Hollylynne Stohl Lee 《Educational Studies in Mathematics》2008,68(3):247-261

In the mathematics education literature, there is currently a debate about the mechanisms by which group discussion can contribute to mathematical learning and under what conditions this learning is likely to occur. In this paper, we contribute to this debate by illustrating three learning opportunities that group discussions can create. In analyzing a videotaped episode of eight middle school students discussing a statistical problem, we observed that these students frequently challenged the arguments that their colleagues presented. These challenges invited students to be explicit about what mathematical principles, or warrants, they were implicitly using as a basis for their mathematical claims, in some cases recognize the modes of reasoning they were using were invalid and reject these modes of reasoning, and in other cases, attempt to provide deductive support to justify why their modes of reasoning were appropriate. We then describe what social and environmental conditions allowed the discussion analyzed in this paper to occur.

Evaluation of Courses by Whole Student Cohorts: a case study     

Anne M. Powell  Adrian Hunt  Ann Irving 《Assessment & Evaluation in Higher Education》1997,22(4):397-404

In a climate of unprecedented change in higher education (HE), accurate and immediate course feedback information is vital to the management of institutions, in assisting the development of course material relevant to present student needs. Student contribution to qualitative course evaluation is commonplace although use of relatively small representative groups of students is usual. However, with class sizes increasing — between 100 and 200 is now common — the ability to acquire accurate qualitative evaluation, representatively, is a major issue. This paper describes a methodology providing opportunity for whole cohort groups of students to be involved simultaneously in the generation of feedback. It considers the effectiveness of student consultation meetings as a collection method, the utility of the results in the course development process, how the issues raised and discussed compare with matters included on a university‐wide questionnaire, and whether participating students feel inhibited in discussing matters so publicly.  相似文献
