News or Noise?

This study investigates the quality of the U.S. News annual ranking of national universities and liberal arts colleges. The main finding is that current rankings changes have a strong tendency to revert over the following two rankings. Using a simple model, this study estimates that about 70 to 80 percent of the variation in rankings changes is transitory and reversible. Thus, most of the news in the annual rankings is essentially meaningless noise. An analysis of possible explanations suggests that the noise in annual ranking changes is most likely due to various measurement, estimation, and other information processing errors in the rankings' underlying components.     

Not yet where we want to be： South Africa＇s participation in SITES 2006

The International Association for the Evaluation of Educational Achievement （IEA） initiated the Second International Technology in Education Study （SITES）--A longitudinal large-scale international comparative survey on the use of information and communication technologies （ICTs） in schools. The goal is to understand how ICTs effect teaching and learning in schools. SITES 2006 was the third module in this program to determine how teachers use ICTs, and to find out how school and education system factors influence teachers＇ pedagogical orientation. SITES 2006 administered three questionnaires： one for school principals, one for technology coordinators, and one for mathematics and science teachers, around 400 schools in each of 23 education systems. The main study took place during 2005-2007. This paper describes the South African educational context, provides an overview of the South African participation, speculates on South Africa＇s future participation, and provides a comparative glimpse of the use of ICTs in South African mathematics and science classrooms.     

An explorative learning approach to teaching clinical anatomy using student generated content

Translating basic sciences into a clinical framework has been approached through the implementation of various teaching techniques aimed at using a patient case scenario to facilitate learning. These techniques present students with a specific patient case and lead the students to discuss physiological processes through analysis of provided data supported by independent learning and research. However, no literature exists that describes a reverse teaching methodology in which students are given disease diagnosis and then asked to construct a patient case. This article discusses an explorative learning approach introduced in the gross anatomy course in which students were asked to use clinical skills and reasoning to create a patient case. The online knowledge‐sharing portal utilizing MediaWiki provided a necessary base for students in completing their task. Teams were given 4 weeks to complete their written online project with weekly feedback provided by 3rd year teaching assistants using the Wiki discussion page. A survey was performed to assess competence regarding a patient write up and oral presentation. Skills that the teams acquired through the completion of this project will benefit future patient interactions. This project also emphasized and reinforced the importance of effective communication, leadership, and teamwork. This study shows that a clinical anatomy project that incorporates explorative learning can be an effective way of introducing students to the skills needed for patient write ups and oral presentations. Furthermore this approach to learning allows students to excel during their clinical years and to correlate anatomy to clinical diagnoses.

TM4L: Creating and browsing educational topic maps

In this article, we describe TM4L, an environment for building, maintaining and using standards‐based, ontology‐aware e‐learning repositories. It is based on the idea that concept‐driven access to learning material implemented as a topic map can bridge the gap between a learner and targeted knowledge. One of the driving goals of this work is to increase the reusability of available educational resources by enabling the use of a developed subject ontology with courses on the same subject with different stricture. Another goal of TM4L is to support an efficient context‐based retrieval of learning content tailored to the needs of a learner working on an educational task. The paper focuses on three aspects of the TM4L environment: domain modelling, editing capabilities and the interface for exploring the learning collection. The key features of the TM4L functionality are illustrated with some examples.
