Analysis of three different models used to acquire three e-learning solutions at the same university
The Universtiy of Pretoria has been using an electronic assessment system since 1991 and a learning management system (LMS) since 1998. Both systems required urgent upgrading. In 2003 a further need arose in the Faculty of Health Sciences, for an electronic portfolio system. The Department for Education Innovation has thus implemented three new systems during the past three years: a new electronic assessment system, an upgraded LMS, and an electronic portfolio system. This paper analyzes the adv
Advanced Two- Point Perspective by Dick McConnell Film in preparation. If this is the first time you have attempted measured perspective using the Vertical Plane method, you may find it useful to try drawing a building in two point perspective first. Whilst a simple design, the ‘Global Exhibition Stand’ will give you the chance to [...]
You Are What You Drink!
Contamination in drinking water sources or watersheds can negatively affect the organisms that come in contact with it. The affects can be severe causing illness or, in some cases, even death. It is important for people to understand how they can contribute to the contaminants in drinking water and what treatment can be done to counter these harmful effects. Students will learn about the various methods developed by environmental engineers for treating drinking water in the United States.
All Caught Up: Bycatching and Design
Bycatch, the unintended capture of animals in commercial fishing gear, is one of the hottest topics in marine conservation today. About 25% of the entire global catch is by-catch This surprisingly high level of by-catch is responsible for the decline of hundreds of thousands of dolphins, whales, porpoises, seabirds and sea turtles each year. Through this curricular unit, students will analyze the significance of by-catch in the global ecosystem and propose solutions to help reduce by-catch Stude
Integrating Collaborative Concept Mapping Tools with Group Memory and Retrieval Functions
The provision of shared visual representations is considered to be an important facilitator for creative processes in group working and learning scenarios. Although reusability is an inherent feature of computerised representations in general, a comparative analysis of existing tools shows clear deficits in this respect. We are convinced that reusability and thus sustainability of the results of co-constructive group work can be much enhanced by integrating visual environments with functions for
In this activity, students learn how engineers use solar energy to heat buildings by investigating the thermal storage properties of some common materials: sand, salt, water and shredded paper. Students then evaluate the usefulness of each material as a thermal storage material to be used as the thermal mass in a passive solar building.
Analysis Methods for Collaborative Models and Activities
A classification of analysis methods for CSCL systems is presented which uses as one dimension the distinction into summary analysis and structural analysis and as another distinction different types of raw data: either user actions or state descriptions. The Cool Modes environment for collaborative modeling enables us to explore the whole spectrum of analysis methods. Action logging is based on the MatchMaker communication server underlying Cool Modes. Example instances for several analysis met
Students make Moebius strips and use them to demonstrate the interconnectedness of an environment. They explore the natural cycles water, oxygen/carbon dioxide, carbon, nitrogen that exist within the environment.
What's Gotten Into You?
In this activity, students use models to investigate the process and consequences of water contamination on the land, groundwater, and plants. This is a good introduction to building water filters found in the associated activity, The Dirty Water Project.
In this lesson, students are introduced to the types of renewable energy resources. They are involved in activities to help them understand the transformation of energy (solar, water and wind) into electricity. Students explore the different roles of engineers working in renewable energy fields.

By tracing the movement of radiation released during an accident at the Chernobyl nuclear power plant, students see how air pollution, like particulate matter, can become a global issue.
On the Move
Looking at models and maps, students explore different pathways and consequences of pollutant transport via the weather and water cycles. In an associated literacy activity, students develop skills of observation, recording and reporting as they follow the weather forecast and produce their own weather report for the class.
The No Zone of Ozone
Students explore the causes and effects of the Earth's ozone holes through discussion and an interactive simulation. In an associated literacy activity, students learn how to tell a story in order to make a complex topic (such as global warming or ozone holes) easier for a reader to grasp.
Dripping Wet or Dry as a Bone?
Students use a sponge and water model to explore the concept of relative humidity and create a percent scale.
Designing and evaluating collaboration in a virtual game environment for vocational learning
Especially in vocational education, attention should be paid not only to the use of new technological solutions but also to collaborative learning and cooperative working methods in order to develop students skills for their future jobs. This study involves a design experiment including the design process of a new game environment, description of the script developed for this game, as well as the empirical study with multiple data collection methods, data analysis, results and conclusions for
