Assessing students' ability to trace matter in dynamic systems in cell biology   总被引：1，自引：1，他引：0

College-level biology courses contain many complex processes that are often taught and learned as detailed narratives. These processes can be better understood by perceiving them as dynamic systems that are governed by common fundamental principles. Conservation of matter is such a principle, and thus tracing matter is an essential step in learning to reason about biological processes. We present here multiple-choice questions that measure students' ability and inclination to trace matter through photosynthesis and cellular respiration. Data associated with each question come from students in a large undergraduate biology course that was undergoing a shift in instructional strategy toward making fundamental principles (such as tracing matter) a central theme. We also present findings from interviews with students in the course. Our data indicate that 1) many students are not using tracing matter as a tool to reason about biological processes, 2) students have particular difficulties tracing matter between systems and have a persistent tendency to interconvert matter and energy, and 3) instructional changes seem to be effective in promoting application of the tracing matter principle. Using these items as diagnostic tools allows instructors to be proactive in addressing students' misconceptions and ineffective reasoning.  相似文献

Understanding outcome-based education changes in teacher education: evaluation of a new instrument with preliminary findings     

Christopher Deneen  Gavin T.L. Brown  Trevor G. Bond  Ronnie Shroff 《Asia-Pacific Journal of Teacher Education》2013,41(4):441-456

Outcome-based education (OBE) is a current initiative in Hong Kong universities, with widespread backing by governments and standards bodies. However, study of students’ perceptions of OBE and validation of understanding these perceptions are lacking. This paper reports on the validation of an OBE-specific instrument and resulting preliminary findings. Instrument responses (n = 89) were analysed using Rasch and exploratory/confirmatory factor analyses. Both approaches identified two dimensions (i.e. evaluation and comparison). Challenges and modifications to the instrument items and their relationships to constructs are discussed. Preliminary findings suggest students did not perceive significant differences between OBE and traditionally organised courses. Lack of explicit discussion of OBE with the students may have denied students the ability to make fully informed evaluations of OBE innovations. Implications for instrument validation and evaluation of initiatives in an OBE context are discussed as is the broader issue of transparency in teacher education curriculum design and implementation.  相似文献   

Pre-service educators’ dispositions toward inclusive practices for students with emotional and behavioural difficulties     

Justin D. Garwood  Christopher L. Van Loan 《International Journal of Inclusive Education》2013,17(12):1332-1347

ABSTRACT

In response to challenging behaviour from students with emotional and behavioural difficulties (EBD), teachers around the world often label students as challenging, defining them by their disability. Negative views of students with EBD are a barrier to their inclusion and a major challenge for policy in the United States and elsewhere associated with access to the education system for students with disabilities. Pre-service teacher education has been highlighted as an optimum time to instil in pre-service educators a more equitable disposition toward behaviour management and inclusive practices. Therefore, the purpose of the current mixed-methods study was to assess whether or not an undergraduate course focused on relationship-based approaches to positive behaviour support could impact pre-service educators’ dispositions toward inclusive classroom practices for students with EBD. Survey results from 41 pre-service educators indicated that participants made significant improvements in their knowledge and understanding of compassionate behaviour management, intentional relationship building, and establishment of a welcoming classroom environment. Analysis of participants’ written responses to open-ended questions revealed several themes regarding changes in dispositions toward students with EBD. Implications for pre-service educator preparation and inclusion of students with EBD are discussed.  相似文献   

Peer‐assisted Student Support at the University of Glamorgan: innovating the learning process?     

Christopher Miller  Gary Packham 《Mentoring & Tutoring: Partnership in Learning》2013,21(1):81-95

This article analyses the overall performance of the Peer‐Assisted Student Support (PASS) Scheme in the Business School at the University of Glamorgan. Observations were made over a seven‐week period to measure the effectiveness of the scheme in terms of enhancing the student learning process. Weekly attendance was measured to establish patterns of demand in terms of age, gender and mentored subject area. Further quantitative and qualitative research was undertaken to provide an insight into the perceived benefits of the scheme in relation to student social development and academic performance. The empirical findings of this article show that PASS attendance is female dominated. Moreover, the research suggests that contrary to previous research, the majority of benefactors reside in the under‐21 age group. The findings also highlight that academic and laboratory‐based subjects are a considerable strain on PASS resources and more significantly superior academic performance is positively correlated with regular PASS attendance.  相似文献   

Using a structural equation modelling approach (SEM) to examine leadership of heads of subject departments (HODs) as perceived by principals and vice-principals,heads of subject departments and teachers within ‘school based management’ (SBM) secondary schools: some evidence from Hong Kong     

Loretta Au  Nigel Wright  Christopher Botton 《School Leadership & Management》2013,33(4):481-498

This article reports the use of a Structural Equation Modelling (SEM) technique as a means of exploring our understanding of the leadership of Heads of Subject Departments within School Based Management (SBM) secondary schools in Hong Kong. Arguments made by Gronn (1999, 2000), Spillane et al. (2001) suggest that studies of leadership need to focus more on a distributed model rather than seeing leadership as residing solely in the titular head of the organisation. Other recent studies (Busher & Harris 1999; Harris 2001) have examined the role of middle managers. This article explores SEM as a means of offering important measurement and insight in this complex area. The structural models generated and presented support a new integrative model of the leadership activities and behaviours of the HODs within SBM secondary schools in Hong Kong. Some initial findings (Au 2003) are reported based on a return rate of 83% from a dataset of 2739 teachers, HODs, school principals and vice- principals taken from a sample of 110 government and non-government SBM secondary schools in Hong Kong.  相似文献   

The passion of successful leadership     

Christopher Day 《School Leadership & Management》2013,33(4):425-437

This paper reports multiperspective research on 10 successful, experienced headteachers working in a range of urban and suburban schools of different sizes (with different school populations and free school meals indices of between 20% and 62%). All had raised the levels of measurable pupil attainments in their schools and all were highly regarded by their peers. A key characteristic among the heads was that, regardless of styles and strategies, all revealed a passion for education, for pupils and for the communities in which they worked. The research revealed that the 10 headteachers sustained their success by the application of the a combination of 10 essential leadership qualities, skills and principles and that these enabled them to manage a number of tensions and dilemmas associated with the management of change. Fundamental to the achievement of success, however, was their passion for students, school and community. This paper explores the nature of this passion in relation in particular to six factors which are fundamental to success; achievement, care, collaboration, commitment, trust and inclusivity.1 This research is part of a longitudinal, international, eight country study (ISSLP) which is seeking to establish cross‐country, cross‐cultural comparisons of successful headship in Australia, Canada, China, Denmark, England, Norway, Sweden and the USA. For details of this project see: www.oise.utoronto.ca/～schoolleadership/ssl.html. The English study on which this research is based was financially supported by N.C.S.L., NAHT and S.H.A.   相似文献

Getting the information and communications technology formula right: access + ability = confident use     

Christopher O'Mahony 《Technology, Pedagogy and Education》2013,22(2):295-311

Abstract

The author reports on a study investigating the use of information and communications technology (ICT) by academic and nonacademic staff at an independent English secondary school. Three key areas were investigated: access to ICT both in and outside the school, the perceived and desired ICT ability of staff, and the issues preventing increased use of ICT in teaching, learning and administration. Results showed that a major challenge facing the school was not access to ICT resources, but the provision of relevant and supportive training for staff  相似文献
