A River Ran Through It
Students learn how water is used to generate electricity. They investigate water’s potential-to-kinetic energy transformation in hands-on activities about falling water and waterwheels. During the activities, they take measurements, calculate averages and graph results. Students also learn the history of the waterwheel and how engineers use water turbines in hydroelectric power plants today. They discover the advantages and disadvantages of hydroelectric power. In a literacy activity, students
Thar She Blows!
Students learn about wind as a source of renewable energy and explore the advantages and disadvantages wind turbines and wind farms. They also learn about the effectiveness of wind turbines in varying weather conditions and how engineers work to create wind power that is cheaper, more reliable and safer for wildlife.
How internal and external scripts guide argumentative knowledge construction in a web-based collabor
Collaboration scripts are a powerful means to improve collaborative inquiry learning. More specifically, they can be designed to support argumentative knowledge construction, a core activity in inquiry learning. However, not only externally induced collaboration scripts but also the learners’ internal scripts on collaborative argumentative knowledge construction influence the way they argue with scientific concepts and evidence, thereby affecting what kind of knowledge is acquired during colla
Work and Power: Waterwheel
Investigating a waterwheel illustrates to students the physical properties of energy. They learn that the concept of work, force acting over a distance, differs from power, which is defined as force acting over a distance over some period of time. Students create a model waterwheel and use it to calculate the amount of power produced and work done.
An Evolutionary Approach to Prototyping Pedagogical Agents: From Simulation to Integrated System
We have developed and integrated software agents with two educational groupware systems (TeamWave Workplace and FLE), using evolutionary prototyping and empiricalbased design as development techniques. The resulting prototypes of pedagogical agents (CoPAS, SA-Agent and RuleEditor) provide learners and teachers with increasingly domain-specific support for distributed collaborative learning activities. Employing the evolutionary approach has enabled us to build and evaluate early prototypes of co
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.
Adaptive learning scenarios for detection of misconceptions about electricity and remediation
Our main objective is to model the knowledge used by learners in order to solve problems about electricity. We are searching means to do a diagnosis about student's activity based on a microworld of electric circuits. Once the diagnosis realized, we try to provide the learner with the most relevant remediation with regard to his/her misconceptions.
Exploring the mathematics of motion through construction and collaboration.
In this paper we give a detailed account of the design principles and construction of activities designed for learning about the relationships between position, velocity and acceleration, and corresponding kinematics graphs. Our approach is model-based, that is, it focuses attention on the idea that students constructed their own models – in the form of programs – to formalise and thus extend their existing knowledge. In these activities, students controlled the movement of objects in a prog
Generating reports of graphical modelling processes for authoring and presentation
Today's computer supported modelling environments could provide much more information about the users’ actions and problem solving processes than they usually store for later usage. Thus, relevant information about learning processes which could be used for reflection and analysis is lost. This paper describes an approach to tackle this issue by generating “reports”, in the sense of augmented summaries of states and action traces from modelling processes. This approach includes a) gatherin

It’s all In the Package
In this activity, students explore the concept of “reducing” solid waste and how it relates to product packaging and engineering advancements in packaging materials. Students read about and evaluate the highly publicized packaging decisions of two major U.S. corporations. They will evaluate different ways to package items in order to minimize the environmental impact, while considering issues such as cost, availability, product attractiveness, etc. Students will explore “hydrapulping” an

This paper describes a theoretical analysis and experimental investigation of difficulty related distraction by conflicting goal intentions in learning and problem solving with hypertext. Log files are used to capture hypertext navigation in the face of opportunities to implement competing goal intentions. We study how differences in task difficulty influence the volitional protection of the current goal intention. First attempts to integrate volitional processes of action control into cognitive
Students read and evaluate descriptions of how people live “off the grid” using solar power and come to understand better the degree to which that lifestyle is or is not truly independent of technological, economic and cultural infrastructure and resources. In the process, students develop a deeper appreciation of the meaning of “community” and the need for human connection. This activity is geared towards fifth-grade and older students and Internet research capabilities are required. Po
The communication focuses on the implementation of an innovative model for creation of online resources and e-learning activities on a web platform dedicated to environmental education. All activities take place in the frame of Minerva project OCTOPUS: "Transnational on-line resource centre". The resource centre implements a mechanism of multilevel knowledge development and information retrieval system using modern electronic tools. This model is dynamic by its technological structure and also f
A white paper is a focused analysis often used to describe how a technology solves a problem. In this literacy activity, students write a simplified version of a white paper on an alternative electrical power generation technology. In the process, they develop their critical thinking skills and become aware of the challenge and promise of technological innovation that engineers help to make possible. This activity is geared towards fifth grade and older students and computer capabilities are req
This paper introduces Collage, a high-level IMS-LD compliant authoring tool that is specialized for CSCL (Computer-Supported Collaborative Learning). Nowadays CSCL is a key trend in e-learning since it highlights the importance of social interactions as an essential element of learning. CSCL is an interdisciplinary domain, which demands participatory design techniques that allow teachers to get directly involved in design activities. Developing CSCL designs using LD is a difficult task for teach
Students drop water from different heights to demonstrate the conversion of water’s potential energy to kinetic energy. They see how varying the height from which water is dropped affects the splash size. They follow good experiment protocol, take measurements, calculate averages and graph results. In seeing how falling water can be used to do work, they also learn how this energy transformation figures into the engineering design and construction of hydroelectric power plants, dams and reserv
