Multi‐level Assessment of Scientific Content Knowledge Gains Associated with Socioscientific Issues‐based Instruction

This study explored the impact of using a socioscientific issue (SSI) based curriculum on developing science content knowledge. Using a multi‐level assessment design, student content knowledge gains were measured before and after implementation of a three‐week unit on global warming (a prominent SSI) that explored both the relevant science content and the controversy surrounding global warming. Measures of student content knowledge were made using a standards‐aligned content knowledge exam (distal assessment) and a curriculum‐aligned exam (proximal assessment). Data were collected from 108 students enrolled from two schools. Quantitative analysis of the distal assessment indicated that student post‐test scores were statistically significantly different than their pre‐test scores (F = 15.31, p<0.001). Qualitative analyses of student responses from the proximal assessment indicated that students, on average, expressed more accurate, more detailed, and more sophisticated understandings of global warming, the greenhouse effect, and the controversy and challenges associated with these issues following the three‐week unit. Combined results from the proximal and distal assessments explored in this study offer important evidence in supporting the efficacy of using SSI as contexts for science education. In addition to a discussion of the components of an SSI‐based curriculum, this study provides support for the use of SSI as a context for learning science content.     

Influence of longswing technique on the kinematics and key release parameters of the straddle Tkachev on uneven bars

Tkachev on uneven bars is a release and re-grasp skill performed using variations of preparatory longswing techniques; the reasons why different techniques are chosen remains unclear. This study examined kinematic and key release parameters specific to three distinct techniques with the aim of understanding the relative benefits of each. During two international artistic gymnastics competitions six arch, straddle and pike longswings preceding the straddle Tkachev were recorded using twin video cameras. Calibration and movement images were digitised and reconstructed using 3D DLT. Shoulder and hip angular kinematics, angular momentum and key release parameters were compared between techniques. In the arch longswing, the first and second hip functional phases began significantly earlier than the straddle or pike. No significant differences were established for release parameters although large effect sizes for horizontal release velocity and angular momenta about the mass centre and bar were reported between the arch and other two variants. Therefore, the arch variant may provide the opportunity to develop more complex combinations following the Tkachev. Providing insight into mechanical advantages of specific longswing techniques, and highlighting those that elicit desirable characteristics offers the potential to provide coaches with objective data on technique selection and ultimately skill development.     

Collaborative Testing Improves Performance but Not Content Retention in a Large-Enrollment Introductory Biology Class

Collaborative testing has been shown to improve performance but not always content retention. In this study, we investigated whether collaborative testing could improve both performance and content retention in a large, introductory biology course. Students were semirandomly divided into two groups based on their performances on exam 1. Each group contained equal numbers of students scoring in each grade category (“A”–“F”) on exam 1. All students completed each of the four exams of the semester as individuals. For exam 2, one group took the exam a second time in small groups immediately following the individually administered test. The other group followed this same format for exam 3. Individual and group exam scores were compared to determine differences in performance. All but exam 1 contained a subset of cumulative questions from the previous exam. Performances on the cumulative questions for exams 3 and 4 were compared for the two groups to determine whether there were significant differences in content retention. Even though group test scores were significantly higher than individual test scores, students who participated in collaborative testing performed no differently on cumulative questions than students who took the previous exam as individuals.     

Healthcare librarians and the delivery of critical appraisal training: attitudes, level of involvement and support

Background: Although healthcare librarians are undertaking training in critical appraisal skills, what is not so clear is the impact of the training on the understanding and dissemination of these skills. Objectives: This study aims to examine the attitudes of healthcare librarians towards delivering critical appraisal training and their level of involvement. Methods: A questionnaire survey of 57 library services across 48 NHS Trust Library Services in north‐west England followed up with 21 semi‐structured interviews. Results: Seventy‐three per cent of respondents felt that they ought to be involved in delivering critical appraisal training, however less than a third (29%) are actually involved. Librarians are involved in critical appraisal facilitation at various levels. Conclusions: Debate continues over the extent of librarian involvement in delivering critical appraisal training. As long as healthcare librarians recognise their own capabilities and identify the boundaries within which they feel comfortable then there is no reason why they should not be involved in delivering critical appraisal training.     

Alphabet knowledge in preschool: A Rasch model analysis

In this study, we used Rasch model analyses to examine (1) the unidimensionality of the alphabet knowledge construct and (2) the relative difficulty of different alphabet knowledge tasks (uppercase letter recognition, names, and sounds, and lowercase letter names) within a sample of preschoolers (n = 335). Rasch analysis showed that the four components of alphabet knowledge did work together as a unidimensional construct, indicating all alphabet tasks administered were measuring the same underlying skill. With regard to difficulty of tasks, letter recognition was easier than letter naming, which in turn was easier than letter sounds, and uppercase letter names were easier than lowercase letter names. Most notably, most of the alphabet tasks overlapped, and the Rasch models for the single tasks were no more reliable than the combined measure. This suggests that these alphabetic tasks do not measure distinct skills but are instead indicators of a single ability. Consequently, we support the conceptualization of alphabet knowledge as a unitary construct, and suggest that those assessing and teaching alphabet knowledge in preschool use tests and methods that combine the various alphabetic tasks rather than separating them. These combined assessments will be more likely to capture the range of abilities within a preschool sample and avoid the floor and ceiling effects that have so often complicated early literacy research.     

Shifting relations with the more-than-human: six threshold concepts for transformative sustainability learning

Using the iterative process of action research, we identify six portals of understanding, called threshold concepts, which can be used as curricular guideposts to disrupt the socially constituted separation, and hierarchy, between humans and the more-than-human. The threshold concepts identified in this study provide focal points for a curriculum in transformative sustainability learning which (1) acknowledges non-human agency; and (2) recognizes that the capacity to work with multiple ways of knowing is required to effectively engage in the process of sustainability knowledge creation. These concepts are: there are different ways of knowing; we can communicate with non-human nature and non-human nature can communicate with us; knowing is relational; transrational intuition and embodied knowing are valuable and valid ways of knowing; worldview is the lens through which we view reality; and the power of dominant beliefs (represented in discourse) supports and/or undermines particular ways of knowing and being as in/valid.     

Open Learning,Electronic Communications and Beginning Teachers

The largest post graduate initial teacher education course in the UK was introduced by the Open University in February 1994. The course is innovative in a number of ways: it is the first large scale distance taught pre‐service course in the UK; all students are loaned a computer for the duration of the course; and computer conferencing is used extensively for communication between students, part‐time tutors and the course team. In this paper the use of the computer conferencing element is described and evaluated, and ways in which electronic communications can be developed for this to be a truly effective medium for supporting the development of beginning teachers’ competence and confidence are discussed.     

Educating Community Intellectuals: Rhetoric, Moral Philosophy, and Civic Engagement

This article encourages technical and professional communication programs to take on the challenge of educating students to become “community intellectuals.” The notion of educating future professionals for a career needs to be reconsidered in light of both current research concerning civic rhetoric and past practices in moral humanism courses. The triumvirate of rhetoric, ethics, and moral philosophy provides an effective foundation for reconfiguring existing pedagogy in the field and offers insights for nurturing community intellectuals.     

Indiana women of achievement: using self-directedness,self-efficacy and self-determination to explore opportunities for leadership

This article shares examples of how leadership opportunities, self-directedness, self-efficacy and self-determination developed in professional women who have been recognised as leaders. This study presents six women honoured as ‘Women of Achievement’. Through narrative interviews, each woman described aspects of her life that guided decision-making and her approach to various life situations. Using the narrative examples provided, one may be able to see themes or strategies for working with other learners to enhance their own leadership. Findings included: growth and development as leaders within their own environments and through interactions with people who mentored or influenced them; openness to opportunities presented to them; the effect that time, place and culture contributed to the goals and tasks that these women undertook. While they were bound by social constraints concerning gender, race and class, each found a way to adapt within those environments and make changes for the better through their contributions. Consistently, these women realised their actions made a difference. Implications for further research include: enhancing self-directedness, self-efficacy and self-determination in women; expanding the definition of leadership; and understanding the motivation for engaging in leadership opportunities. Through this and other research, we seek to expand women’s roles and participation as leaders.     

From attitudes to practice: utilising inclusive teaching strategies in Kenyan primary schools

The purpose of this paper is to provide evidence of Kenyan primary school teachers using inclusive teaching strategies in a rural setting with many known barriers to the development of a sustainable inclusive education system. This qualitative study examines teachers’ uses of inclusive teaching strategies in primary schools following a series of teacher trainings, classroom observations, individual semi-structured teacher conferences, reflective lesson plans, and pre- and post-questionnaires. Moving beyond legal mandates and attitudinal assessments, the outcomes of this study demonstrate that in a short time, and among a small sample of teachers, administrators, and Ministry officials, a culturally responsive approach to implementing inclusive learning strategies proved beneficial for meeting the needs of diverse primary school students in western Kenya.
