Middle School Portal: Math and Science Pathways (MSP2)
This online activity challenges students to think about and use percentages related to television viewing to make comparisons to determine television viewing preferences. The activity is one of 80 mathematical challenges featured on the Figure This! web site emphasizing real-world uses of mathematics. To answer this activity's initial question, the student reads data from a chart, applies a formula, and uses the calculated information to draw a conclusion about TV viewing preferences. Informatio

Virtual Learning Environments as a Supplement to Traditional Teaching
Many factors influence teaching nowadays. Numbers of students are increasing, some students pay for studies and require more flexible teaching, more students have access to Internet, the learning material is changing rapidly (especially of subjects, related to information technologies), publishing industry is slow and expensive. All that stimulates usage of modern technologies in education. Virtual Learning Environments (VLEs) is one of the forms of e-learning. They open new ways of teaching and

Half-Baked Logo Microworlds as Boundary Objects in Integrated Design
The paper addresses the problem of fragmentation of the communities involved in the design of digital media for education. It draws on the experience gained at the Educational Technology Lab in the design of Logo-based microworlds with three different platforms respectively based on component computing, 3D game engines and 3D navigation with a GIS. In this paper I use the term half-baked to describe a microworld which is explicitly designed to engage its users with changing it as the main aspect

Information Technologies for Biology Education: Computerized Electrophysiology of Plant Cells
Biology has moved from a bench-based discipline to a bioinformational science in modern times but application of computational and analytical methods of informatics in it is still a problem for many researchers and students of biology. We suggest to integrate cost effective and practical combination of the real and the virtual laboratories into the undergraduate biological science curriculum. This laboratory work illustrates passive and active electrical properties of plant cell membranes while

Why Web 2.0 is Good for Learning and for Research: Principles and Prototypes
The term "Web 2.0" is used to describe applications that distinguish themselves from previous generations of software by a number of principles. Existing work shows that Web 2.0 applications can be successfully exploited for technology-enhance learning. However, in-depth analyses of the relationship between Web 2.0 technology on the one hand and teaching and learning on the other hand are still rare. In this article, we will analyze the technological principles of the Web 2.0 and describe thei

Motor-Manipulatory Behaviours and Learning: an Observational Study
In this paper we investigated the role of motor-manipulatory behaviour in the learning modalities of thirty-five primary school children interacting with a Lego MindStorms kit. In particular, by means of an observational taxonomy of children’s behaviour, we analysed the video records of two observational sessions regarding the learning activities during the building of a small robot. Our results demonstrated that motormanipulatory behaviours are strictly linked to cognitive processes, and that

Learning through investigative games and internet on-line activities
Internet is an important phenomenon in our society and already become one of the mostly used media around the world. In human history this is the first media, which is broadly used in so little time. Obviously, it plays an important role also in the life of our children. They use it for communication with each other (chat, email), they use it for finding new information to school, and they search the web or even create their own websites. The investigative games on internet are competitions, thr

The Remote Control Approach - How to Apply Scaffolds to Existing Collaborative Learning Environments
In this paper we present an architecture for the integration of tutoring and process scaffolds into existing collaborative applications. The architecture allows to combine existing research results concerning collaborative processes and their formalization, and existing and tested collaborative learning environments. The architecture allows to control the learning environments either by a human or a pedagogic agent. Both types of tutors are using the same set of primitives - either via an intuit

Reducing cognitive load and fostering cognitive skill acquisition: Benefits of category-avoiding exa
In this paper, we provide evidence against the common idea that worked examples should be designed to convey problem categories and category-specific solution procedures. Instead we propose that instructional examples should be designed in a way that supports the understanding of relations between structural problem features and individual solution steps, i.e. relations that hold below the category level. We illustrate in the domain of probability word problems how category-avoiding instructiona

Using A Simulated Student for Instructional Design
In this paper, I describe how a cognitive model was used as a simulated student to help design lessons for training circuit board assemblers. The model was built in the Soar cognitive architecture, and was initially endowed with only an ability to learn instructions and prerequisite knowledge for the task. Five lessons, and a total of 81 instructions for teaching expert assembly were developed by iteratively drafting and testing instructions with the simulated student. The resulting instructions

Meanings for Fraction as Number - Measure by Exploring the Number Line
Construction of meanings for fraction as number-measure is studied during the implementation of exploratory tasks concerning comparison and ordering of fractions as well as operations with fractions. 12-year-old students were working collaboratively in groups of two with software that combines graphical and symbolic notation of fractions represented as points on the number line. Fractions as points and segments, ordering fractions as part of kinesthetic activities and abstracting the scaling of

Adaptive and context-aware scenarios for technology-enhanced learning system based on a didactical t
Among the main issues of future technology-enhanced learning systems, we can mention the following ones: the ability to reuse learning resources (learning objects, tools and services) from large repositories, to take into account the context and to allow dynamic adaptation to different learners based on substantial advances in pedagogical theories and knowledge models. In our framework, the goal of scenarios is to describe the learning and tutoring activities to acquire some knowledge domain (fo

Combining Knowledge Awareness and Information Filtering in an Open-ended Collaborative Learning Envi
Knowledge awareness (KA) has been proposed to increase collaboration opportunities in an open ended and collaborative learning environment. To encourage collaboration, an individual userâs agent called KA-Agent autonomously informs the learner about up-to-the-minute activities from other learners. For instance, a message might be ãsomeone is looking at the same knowledge that you are looking at.ä Although this message, called active KA, is very useful to create real-time collaboration, a larg
