Paradigm revisited: Another look at the physical and social sciences     

Bruce R. Lewis  Mr. Theo R. Leverenz 《Research in higher education》1979,11(1):85-94

The study reexamines the paradigm concept as presented by Lodahl and Gordon with respect to the concept of consistency in professional life. The results show that high paradigm disciplines are more consistent than low paradigm disciplines on selected measures of educational background and professional activity. The conclusions of this investigation suggest first that the paradigm concept works well by itself in researching academic professions, and second that the concept of consistency offers a new way of both classifying faculty and exploring the dimensions of faculty characteristics.  相似文献   

Assessing end-use relevance of public sector research organisations     

Catherine Lyall  Ann Bruce  Marion Firn 《Research Policy》2004,33(1):73-87

Measuring the effective impact of research and its relevance to society is a difficult undertaking but one that the public sector is keen to embrace. Identifying end-users of research and capturing their views of research relevance are challenging tasks and not something that has been extensively reported. The evaluation of end-use relevance demands a shift in organisational mindset and performance indicators away from readily quantifiable outputs towards a consideration of more qualitative end-user outcomes that are less amenable to measurement, requiring both a greater tolerance of ambiguity and a willingness to learn from the evaluation process.  相似文献   

Using the Critical Thinking Belief Appraisal to assess the rigor gap     

Bruce Torff 《Learning Inquiry》2008,2(1):29-52

In a line of research employing a survey instrument, the Critical Thinking Belief Appraisal, teachers supported critical-thinking (CT) activities more for high- than low-advantage learners, likely exacerbating a “rigor gap” implicated in persistent achievement gaps. Such beliefs were less likely to be espoused by expert teachers than randomly selected ones, and teacher-education programs mitigated these beliefs but did not expunge them, suggesting a need for interventions that foster belief change. Six issues were found to be associated with support for low-CT activities with low-advantage populations—learners’ prior knowledge, time constraints, influence of parents, influence of colleagues, learners’ level of motivation, and learners’ level of ability. The rigor gap may be ameliorated through teacher-education practices that encourage teachers to (a) reflect on their existing beliefs, their experiences as students, their field experiences, classroom scenarios, and models of best practice, and (b) create instructional plans featuring high-CT activities for low-advantage learners.  相似文献   

The influence of elbow joint kinematics on wrist speed in cricket fast bowling     

Kane Jytte Middleton  Jacqueline Anne Alderson  Bruce Clifford Elliott  Peter Michael Mills 《Journal of sports sciences》2015,33(15):1622-1631

This modelling study sought to describe the relationships between elbow joint kinematics and wrist joint linear velocity in cricket fast bowlers, and to assess the sensitivity of wrist velocity to systematic manipulations of empirical joint kinematic profiles. A 12-camera Vicon motion analysis system operating at 250 Hz recorded the bowling actions of 12 high performance fast bowlers. Empirical elbow joint kinematic data were entered into a cricket bowling specific “Forward Kinematic Model” and then subsequently underwent fixed angle, angular offset and angle amplification manipulations. A combination of 20° flexion and 20° abduction at the elbow was shown to maximise wrist velocity within the experimental limits. An increased elbow flexion offset manipulation elicited an increase in wrist velocity. Amplification of elbow joint flexion–extension angular displacement indicated that, contrary to previous research, elbow extension range of motion and angular velocity at the time of ball release were negatively related to wrist velocity. Some relationships between manipulated joint angular waveforms and wrist velocity were non-linear, supporting the use of a model that accounts for the non-linear relationships between execution and outcome variables in assessing the relationships between elbow joint kinematics and wrist joint velocity in cricket fast bowlers.  相似文献   

Connecting Education,Welfare, and Health for American Families     

Bruce S. Cooper 《Peabody Journal of Education》2015,90(5):659-676

The relationship of education to social mobility, health, and socioeconomic stability is examined in this study. The central question is: how do educational access and attainment reduce poverty and increase social immersion in a system that affords opportunity for quality health care and economic prosperity? An historic perspective, related and compared to current conditions for those who live at or below the poverty line, highlights the extreme difficulties of overcoming the barriers that separate people from consistent quality education, access to quality health care, and the opportunity to move toward economic independence.

The latest statistics showing the significance of socioeconomic status (SES) to cognitive development, educational achievement, healthy living, and social mobility are factors that have and continue to affect large portions of America's poor. The increase of early childhood programs is a beneficial first step in closing the achievement gap, but the physical and mental health problems plaguing the poor must be addressed if we are to reduce the poverty rate and improve educational opportunities for all children.  相似文献   

Students' experience of problem-based learning in virtual space     

Peter Gibbings  John Lidstone  Christine Bruce 《高等教育研究与发展》2015,34(1):74-88

This paper reports outcomes of a study focused on discovering qualitatively different ways students experience problem-based learning in virtual space. A well-accepted and documented qualitative research method was adopted for this study. Five qualitatively different conceptions are described, each revealing characteristics of increasingly complex student experiences. Establishing characteristics of these more complex experiences assists teachers in facilitating students’ engagement and encouraging deeper learning.  相似文献   

Building the BIKE: Development and Testing of the Biotechnology Instrument for Knowledge Elicitation (BIKE)

Identifying students’ conceptual scientific understanding is difficult if the appropriate tools are not available for educators. Concept inventories have become a popular tool to assess student understanding; however, traditionally, they are multiple choice tests. International science education standard documents advocate that assessments should be reform based, contain diverse question types, and should align with instructional approaches. To date, no instrument of this type targeting student conceptions in biotechnology has been developed. We report here the development, testing, and validation of a 35-item Biotechnology Instrument for Knowledge Elicitation (BIKE) that includes a mix of question types. The BIKE was designed to elicit student thinking and a variety of conceptual understandings, as opposed to testing closed-ended responses. The design phase contained nine steps including a literature search for content, student interviews, a pilot test, as well as expert review. Data from 175 students over two semesters, including 16 student interviews and six expert reviewers (professors from six different institutions), were used to validate the instrument. Cronbach’s alpha on the pre/posttest was 0.664 and 0.668, respectively, indicating the BIKE has internal consistency. Cohen’s kappa for inter-rater reliability among the 6,525 total items was 0.684 indicating substantial agreement among scorers. Item analysis demonstrated that the items were challenging, there was discrimination among the individual items, and there was alignment with research-based design principles for construct validity. This study provides a reliable and valid conceptual understanding instrument in the understudied area of biotechnology.  相似文献   

Longitudinal Stability of Phonological and Surface Subtypes of Developmental Dyslexia     

Robin L. Peterson  Bruce F. Pennington  Richard K. Olson  Sally J. Wadsworth 《Scientific Studies of Reading》2014,18(5):347-362

Limited evidence supports the external validity of the distinction between developmental phonological and surface dyslexia. We previously identified children ages 8 to 13 meeting criteria for these subtypes (Peterson, Pennington, & Olson, 2013) and now report on their reading and related skills approximately 5 years later. Longitudinal stability of subtype membership was fair and appeared stronger for phonological than surface dyslexia. Phonological dyslexia was associated with a pronounced phonological awareness deficit, but subgroups otherwise had similar cognitive profiles. Subtype did not inform prognosis. Results provide modest evidence for the validity of the distinction, although not for its clinical utility.  相似文献   

Promoting early career teacher resilience: a framework for understanding and acting     

Bruce Johnson  Barry Down  Rosie Le Cornu  Judy Peters  Anna Sullivan  Jane Pearce 《Teachers and Teaching》2014,20(5):530-546

In this paper, we undertake a brief review of the ‘conventional’ research into the problems of early career teachers to create a juxtaposed position from which to launch an alternative approach based on resilience theory. We outline four reasons why a new contextualised, social theory of resilience has the potential to open up the field of research into the professional lives of teachers and to produce new insights into the social, cultural and political dynamics at work within and beyond schools. We then move from these theoretical considerations to explain how we used them in a recent Australian research project that examined the experiences of 60 graduate teachers during their first year of teaching. This work led to the development of a Framework of Conditions Supporting Early Career Teacher Resilience which we outline, promote and advocate as the basis for action to better sustain our graduate teachers in their first few years of teaching. Finally, we reflect on the value of our work so far and outline our practical plans to ‘mobilise’ this knowledge in ways that will make it available to a variety of audiences concerned with the welfare of this group of teachers.  相似文献   

Student perceptions of personalised learning: development and validation of a questionnaire with regional secondary students

This project sought to evaluate regional students’ perceptions of their readiness to learn, assessment processes, engagement, extent to which their learning is personalised and to relate these to academic efficacy, academic achievement, and student well-being. It also examined teachers’ perceptions of students’ readiness to learn, the assessment process, engagement, and the extent to which students’ learning is personalised. The sample involved students in years 7–10 from six Victorian secondary schools. An instrument Personalised Learning Environment Questionnaire (PLQ) was developed to measure students’ perceptions of the factors effecting the implementation of Personalised Learning Plans (PLPs). It employed the latest scales to assess a range of PLP indicator variables, with all scales modified for use in an Australian context, and the total number of items kept to a minimum. Only scales more sensitive to PLPs were used to minimise the length of the instrument. There were three outcome variables: academic efficacy, academic achievement, and student well-being. The PLPs were assessed through scales that assess several contributing, distinct dimensions: selfdirected learning readiness, personal achievement, goal orientation, learning environment, personalised teaching and learning initiatives, curriculum entitlement and choice, and perceptions of assessment for learning. The trail PLQ was administered to 220 students, resulting in a 19 scale questionnaire with three or four items per scale. This paper reveals good data to model fit for the majority of items and each scale had good reliability. The paper describes the analytic techniques and results, how the instrument was refined and identifies common and uncommon student perceptions based on a post hoc analysis. The main study consisted of 2,407 students from four schools in the Bendigo Education Plan. They responded to this refined 19 scale version of the PLQ that was developed from the trial PLQ. All scales had satisfactory internal consistency reliability.  相似文献
