A review of the use of video‐conferencing for actuarial education — a three‐year case study

This paper reviews the three‐year history of teaching actuarial studies in live time by video‐conferencing from The University of Melbourne to students at The Australian National University, Canberra. The paper discusses the practicalities of this programme including aspects relating to students, staff and the technology. The outcomes for students at both institutions are presented together with a discussion of a number of issues from the perspectives of the lecturing staff. Some limitations of the programme are also presented.     

Strategies for Broadening Participation in Advanced Technological Education Programs: Practice and Perceptions

Expanding and diversifying the STEM (science, technology, engineering, and mathematics) workforce is a national priority. The National Science Foundation is investing efforts at post secondary education institutions to engage individuals who have been historically underrepresented in STEM. This paper investigated the use of strategies to broaden participation in STEM by grantees of NSF’s Advanced Technological Education (ATE), who are primarily located at 2-year colleges. The ATE program focuses on developing and improving technician training programs to prepare students for employment in fields that rely on advanced technologiessuch as nanotechnology, photonics, and mechatronics. A survey, conducted annually by the authors of this study, was used to collect data from ATE grantees on their use and perceptions of strategies to broaden participation in STEM. The findings showed that strategies related to motivation and access to enhance recruitment are more widely used then strategies that improve retention. Respondents identified strategies related to providing financial assistance, mentoring, and conducting outreach activities as the most effective for reaching and engaging underrepresented minority students in academic programs. Despite these perceptions, these strategies seem to be underutilized among this group.     

Scoring Stability in a Large‐Scale Assessment Program: A Longitudinal Analysis of Leniency/Severity Effects

Although much attention has been given to rater effects in rater‐mediated assessment contexts, little research has examined the overall stability of leniency and severity effects over time. This study examined longitudinal scoring data collected during three consecutive administrations of a large‐scale, multi‐state summative assessment program. Multilevel models were used to assess the overall extent of rater leniency/severity during scoring and examine the extent to which leniency/severity effects were stable across the three administrations. Model results were then applied to scaled scores to estimate the impact of the stability of leniency/severity effects on students’ scores. Results showed relative scoring stability across administrations in mathematics. In English language arts, short constructed response items showed evidence of slightly increasing severity across administrations, while essays showed mixed results: evidence of both slightly increasing severity and moderately increasing leniency over time, depending on trait. However, when model results were applied to scaled scores, results revealed rater effects had minimal impact on students’ scores.     

Musculoskeletal stiffness during hopping and running does not change following downhill backwards walking

Eccentric contractions that provide spring energy can also cause muscle damage. The aim of this study was to explore leg and vertical stiffness following muscle damage induced by an eccentric exercise protocol. Twenty active males completed 60 minutes of backward-walking on a treadmill at 0.67 m/s and a gradient of ? 8.5° to induce muscle damage. Tests were performed immediately before; immediately post; and 24, 48, and 168 hours post eccentric exercise. Tests included running at 3.35 m/s and hopping at 2.2 Hz using single- and double-legged actions. Leg and vertical stiffness were measured from kinetic and kinematic data, and electromyography (EMG) of five muscles of the preferred limb were recorded during hopping. Increases in pain scores (over 37%) occurred post-exercise and 24 and 48 hours later (p < 0.001). A 7% decrease in maximal voluntary contraction occurred immediately post-exercise (p = 0.019). Changes in knee kinematics during single-legged hopping were observed 168 hours post (p < 0.05). No significant changes were observed in EMG, creatine kinase activity, leg, or vertical stiffness. Results indicate that knee mechanics may be altered to maintain consistent levels of leg and vertical stiffness when eccentric exercise-induced muscle damage is present in the lower legs.     

Educational placements and National Curriculum Key Stage 2 test outcomes of children with a history of specific language impairment

As part of their longitudinal investigations of a large cohort with a history of specific language impairment (SLI), Professor Gina Conti-Ramsden and her research team based at the School of Education, University of Manchester, Dr Emma Knox, Dr Nicola Botting and Dr Zoë Simkin report on the changing educational placements and National Curriculum assessment outcomes of 200 children at 11 years. Teacher questionnaires reporting on the Year 6 primary education placements of the sample reveal details about the long-term educational needs of children with SLI.
Furthermore, in exploring the experiences of the sample in the National Curriculum Key Stage 2 tests the present study found that children with SLI perform poorly relative to national expectations of levels of achievement across all tests. At present there are no guidelines for supporting children with SLI in relation to National Curriculum tests and the present data suggests there is an obvious need for these to be developed.     

The Impact of a Professional Development Program on Teachers' Mathematical Knowledge for Teaching,Instruction, and Student Achievement

In this paper, we describe findings from a three-year evaluation of a well-developed mathematics professional development program that is commercially available on a wide scale. The professional development is designed to improve teachers' mathematical knowledge for teaching and to enable them to elicit more student thinking and reasoning during mathematics lessons. Specifically, it focused on helping teachers (a) learn more mathematics, (b) understand how children learn math, (c) use formative assessment to develop insight into what specific students know and do not know, and (d) develop effective classroom instructional strategies that enable student problem solving. Participants included 105 fourth- and fifth-grade teachers teaching in 19 low-income schools within a single district. Teachers were randomly assigned within schools either to a “business as usual” control group or to receive the professional development. The training consisted of a week-long summer institute and four to six in-service days during the school year. The training was run by full-time trained associates. We find some limited evidence of positive impacts on teachers' mathematical knowledge for teaching, but no effects on instructional practice or student outcomes.     

Using representations,decomposition, and approximations of practices to support prospective elementary mathematics teachers’ practice of organizing discussions

This paper examines a series of instructional activities that provide prospective elementary teachers with an opportunity to engage in one of the more difficult practices to learn within mathematics teaching—organizing a mathematical discussion. Within a mathematics methods course, representations and decomposition of practice built from the Five Practices framework (Smith and Stein in Five practices for orchestrating productive mathematics discussions. Corwin Press, Thousand Oaks, CA, 2011) were implemented and studied to examine how prospective elementary teachers set goals, selected and sequenced available student work, and planned questions within a mathematical discussion. We examined prospective elementary teachers’ strengths and weaknesses in these facets through an approximation of practice set in a lesson context familiar to the prospective elementary teachers. Our results demonstrated that although prospective elementary teachers set varying goals for a discussion, their pedagogical choices in planning their discussion tended to be consistent with the goals they have set. These results support the focused development of prospective elementary teachers’ goal setting as an implication for mathematics teacher educators.     

Education with production — learning from the third world

Flexible, self-organised work groups will become increasingly important in rich countries like the U.S. as employment in the formal economic system continues to decline. Educational models and methods based on the linking of learning with productive work developed in Third World countries can give a valuable stimulus to educational innovation in those industrialized countries hardest hit by the current crisis.Education with production will be important in equipping people for the new situation. The article discusses examples of several types of education with production. Among issues raised are: what skills are needed; what sorts of people the different types of post-school education with production cater for; how to extend the benefits of self-organised work; some important factors in introducing education with production at school level, including demands on the teacher and relevance to pupils' needs. The role of the Foundation for Education with Production is briefly described.     

Five critiques of the open educational resources movement

This paper will review existing literature on Open Educational Resources (OER). It is intended to examine and critique the theories which underpin the promotion of OER in higher education, not provide guidance on their implementation. (1) I will introduce the concepts of positive and negative liberty to suggest an under-theorisation of the term ‘open’. (2) OER literature will be shown to endorse a two-tiered system, in which the institution is both maintained and disaggregated. (3) I will highlight a diminishing of the role of pedagogy within the OER vision and the promotion of a learner-centred model for education. (4) This stance will be aligned with humanistic assumptions of unproblematic self-direction and autonomy. (5) I will discuss the extent to which the OER movement aligns itself with economically orientated models of the university. I offer these critiques as a framework for the OER movement to develop as a theoretically rigorous area of scholarship.
