Analyzing Science Education in the United Kingdom

Moon
Characterizing science education dichotomously as either “formal” or “informal” doesn't make sense:


Increasing evidence suggests that individuals develop their understanding of science concepts in and out of school, using varied community resources and networks. Thus in contrast to historic research approaches that focus exclusively on single organizations and/or educational events, the current paper presents exploratory research in which we utilized specific community ecology analytical tools and approaches to describe and analyze the U.K. science education community as a whole. Data suggest that overall the U.K. science education community is highly interconnected, and collaborative within individual sectors and moderately interconnected and collaborative between sectors; schools and to a lesser degree universities were outliers to this pattern. An important conclusion was that management to maximize the effectiveness of science education the U.K. science education community would involve support for continued diversification of the number of science education entities in the system and encouragement of reciprocally collaborative, synergistic relationships. We posit that systemic research enables a broader, more comprehensive view of a system's strengths and weaknesses, offering useful insights into the structure and functioning of science education activities; insights that could help researchers, practitioners, and policy makers improve the overall quality of science education delivery for all.

Increasing Student Engagement with Practical Classes Through Online Pre-Lab Quizzes

Quiz submission rates Laboratory practicals classes are an essential component of all science degrees, but are a pinch point because of rising student numbers, rising student expectations and falling student exposure to laboratory work prior to entering higher education. Augmentation of physical laboratory work with online interventions is not new, but as virtual laboratories become increasingly sophisticated, cutting-edge approaches have become less available to many institutions as they are unable to meet the investment or specialist skills needed to build or maintain these complex tools. This case study examines the possibilities for increasing student engagement with practical work using the simplest tools available in any standard virtual learning environment and available to all. Based on results obtained from a large student cohort, the results indicate that this low-cost, low-tech approach can achieve high levels of student satisfaction.

Peer Assessment - Six is the Magic Number

Moon Peer assessment of high value written assignments? That pretty much describes this week. So this is of interest:


How to achieve accurate peer assessment for high value written assignments in a senior undergraduate course. Assessment & Evaluation in Higher Education 09 Dec 2014 doi: 10.1080/02602938.2014.987721
The psychometric measures of accuracy, reliability and validity of peer assessment are critical qualities for its use as a supplement to instructor grading. In this study, we seek to determine which factors related to peer review are the most influential on these psychometric measures, with a primary focus on the accuracy of peer assessment or how closely peer-given grades match those of an instructor. We examine and rank the correlations of accuracy, reliability and validity with 17 quantitative and qualitative variables for three senior undergraduate courses that used peer assessment on high value written assignments. Based on these analyses, we altered the single most significant variable of one of the courses. We demonstrate that the number of reviews completed per reviewer has the greatest influence on the accuracy of peer assessment out of all the factors analysed. Our calculations suggest that six reviews must be completed per reviewer to achieve peer assessment that is no different from the grading of an instructor. Effective training, previous experience and strong academic abilities in the reviewers may reduce this number.

The problem with wikis

Some time back a student pointed me at this great study of the use of wikis in education:

Grant, L. (2009). ‘I DON’T CARE DO UR OWN PAGE!’ A case study of using wikis for collaborative work in a UK secondary school. Learning, Media and Technology, 34(2), 105-117.

The problem with wikis

Although students in higher education have subtler and more passively aggressive ways of staking their claims to online space and contributions, the problem remains the same - it's mine, hands off! And there is exactly the safe problem in the research community.

And that, dear readers, is the problem with wikis, and why everyone hates them.
