Science Teachers’ Professional Development and Changes in Science Practical Assessment Practices: What are the Issues?

This paper considers the circumstances under which science teachers can respond positively and productively to educational policy reforms in the area of science practical assessment. To understand what might be involved in linking science teachers’ assessment capacities and their professional development, we present illustrative data from recent research studies conducted in Singapore and Hong Kong showing contrasting approaches taken in the implementation of reforms in science practical assessment. In Singapore, teachers worked together to select, discuss, clarify and refine their practices as they made decisions about what to teach and assess. In Hong Kong, teachers took a critical stance towards the new policy and learnt from their own experiences in order to build their confidence. With the same policy initiative, one group of teachers focused more on the technicalities of complying with requirements imposed on them while in the other group had their professional consciousness of what they thought was best for their students provoked so that their practices would be transformed. In an attempt to draw lessons for other contexts in supporting the implementation of assessment policy reforms through professional development work, we identify and discuss a range of factors in science teachers’ professional development that arise once in situ professional development work has started. Overall, our intent in this article is to recast assessment reform as a driver or pivot in teachers’ professional development and learning. To do this it is necessary, we argue, to afford teachers’ experiences and the processes involved in learning from them greater emphasis in order to ensure the continuance of innovation in the assessment of laboratory-based work.     

A Student's View of Engineering

The authors analyze the answers to 10 questions from 523 engineering students in three Michigan junior colleges, in an attempt to elicit the beginning student's view of engineering. The answers give information on the age of first interest in engineering, the age of decision on the field as a career, the influences that led to the choice of engineering, future aspirations, and six other related questions. The opening section briefly states the objectives of education in our society and indicates the contribution of the junior college. The conclusion suggests some specific assistance professional engineers can give to youth.     

Comparison of 2D video and electrogoniometry measurements of knee flexion angle during a countermovement jump and landing task

Quantifying countermovement jump (CMJ) and landing knee flexion angle is important for performance and injury risk assessment. The purpose of the study was to compare electrogoniometer (El-Gon)- and video-derived CMJ and landing knee flexion angle. Twenty-two adults performed three CMJs while knee flexion angle was simultaneously assessed using an El-Gon and video. The average systematic offset (RMSE) of the El-Gon-derived knee flexion angle throughout the entire movement was 7.03°?±?2.69°. Excellent reliability was demonstrated by the El-Gon (ICCavg?=?0.92). Countermovement knee flexion angle, maximum landing knee flexion angle and flexion angle at maximum vertical ground reaction force were 12.0°, 10.9°, and 5.7° higher, respectively, when assessed using El-Gon (p?<?0.001), compared to video. Errors between instruments are likely due to El-Gon crosstalk, misalignment and/or axis determination. The El-Gon is a cost-effective and time-efficient alternative to video analysis for the assessment of knee flexion angle if the error is accounted for and the sensor is precisely attached.     

2008 Community College Futures Assembly Focus: Change Or Die—Keys to Enacting Change in the Community College

The Community College Futures Assembly has served as a national, independent policy thinktank since 1995. Its purpose is to articulate the critical issues facing American community colleges and recognize innovative programs. Convening annually in January in Orlando, Florida, the Assembly offers a learning environment where tough questions are raised, critical issues are discussed, and policy implications are vetted. The focus for the 2008 Community College Futures Assembly was change, a theme taken from the book, Change or Die. This special focus issue of the Community College Journal of Research and Practice highlights the best practices of 30 Bellwether trend-setting institutions.     

Elusive mandate: UNICEF and educational development

The United Nations Children's Fund has rapidly gained prominence as a UN agency promoting educational development. Detailed analysis is presented of UNICEF's transition from being a supplier of emergency goods and services, to a humanitarian role that has diversified to embrace development assistance and promoting the rights of children and women. How these have impacted on the development of UNICEF education is examined. Despite many institutional strengths, it is argued that the need for increased policy clarity in UNICEF education and for greater operational effectiveness remain central to any contemporary understanding of UNICEF's contribution to educational development.     

Unemployment and social class stigmas

Western economies have seen a shift away from a model of job security to a model of work precarity. Cycles of unemployment are a defining feature of the new precarious economy. Given these cycles of unemployment, it becomes imperative to explore the barriers to reemployment. The present study uses stigma communication to explore the intersection of two barriers to reemployment: the stigmatization of unemployment and social class position. Analysis of 40 interviews revealed that the meaning of unemployment changed depending on the perceived social class of an unemployed person. Participants described typical unemployed people as pathologically lazy and unmotivated. Upper class unemployed people were stigmatized as a product of privilege. Middle class unemployed people were relatively unstigmatized. The typical unemployed person merged with the typical unemployed lower class person, suggesting that the dominant meaning of unemployment assumes that unemployment is a lower class phenomenon that is preventable if the lower class person would work harder.
