Physics in Action: Barrel Crunch
Professor Ephraim Fischbach demonstrates barrel crunch in this video from Thinkwell's online Physics series. They began by heating water inside the barrel to create steam. They then capped the barrel to keep the steam inside and poured liquid nitrogen over it to make sure that the can cooled down quickly. The steam condensed and created a partial vacuum. The atmospheric pressure outside the can was stronger than the pressure inside, causing it to collapse. Run time 04:30.
Why Study...James Ussher with Professor Alan Ford
Ussher (1581-1656) is now principally remembered for just one thing: giving the date of the creation as 4004 B.C.! In this video Prof Alan Ford sets him in his context as a great Protestant scholar who made contributions to patristics, biblical studies, and the church and society of his time.
A Bed of Nails
Professor Ephraim Fischbach demonstrates a bed of nails in this video from Thinkwell's online Physics series.

Building on a research trends from various fields, a process-oriented model is adopted to evaluate the instructional potential of games, considering both their surface and deep structure. Two experimental approaches are adopted. Through reflective evaluation the Neurocognitive skills employed, Perceived Competence Facilitation and Perceived usefulness of games are determ
Designing and application of E-portfolio for teacher training
Portfolio is not just a magic word but it is mandatory for everyone in today's free market. Some companies started their own portfolios for employee assessment. Other has them for optimization purposes or even education. Each of us first encounter portfolio in schools. Big books with grades and other useful data were in them. In the teacher education we also have portfolios and the most important is teacher training portfolio. Based on this portfolios employees decide who to hire or not. With th
Can learning from molar and modular worked examples be enhanced by providing instructional explanati
In two experiments we explored how learning from traditional molar worked-out examplesfocusing on problem categories and their associated overall solution proceduresas well as from more efficient modular worked-out exampleswhere intrinsic cognitive load is reduced by breaking down complex solutions into smaller meaningful solution elementscan be further enhanced. Instructional explanations or self-explanation prompts were administered to increase germane cognitive load. However, both int
Student Modeling and Machine Learning
After identifying essential student modeling issues and machine learning approaches, this paper examines how machine learning techniques have been used to automate the construction of student models as well as the background knowledge necessary for student modeling. In the process, the paper sheds light on the difficulty, suitability and potential of using machine learning for student modeling processes, and, to a lesser extent, the potential of using student modeling techniques in machine learn
The role of guidance in computer-based problem solving for the development of concepts of logic
The effect of two instructional variables, manipulation of objects and guidance, in learning to use the logical connective, conditional, was investigated. Instructions for 72 first- and second year social science students were varied in the computer-based learning environment Tarski's World, designed for teaching first-order logic (Barwise &Etchemendy, 1992). Guidance, which was operationalised by giving the learners problems that guided them to all different types of basic problem situations th

Some pre-Web 2.0 best practice examples are analyzed in order to draw the main findings in the paper. The teachers professional qualification designed to meet the new challenges is considered as a key problem for a successful penetration of this phenomenon in the schools. It is emphasized on the importance of designing a lif
PRAXIS - Pervasive Rehabilitation of Aphasia with an eXtensible Interactive System
This thesis describes computer-assisted (CA) methods for the treatment of acquired language impairment in adult aphasics. A key design objective of this project was the elimination of the indirect manipulation of keyboard and mouse (in CA speech language therapy sessions) in favour of the direct manipulation of virtual and physical objects afforded by touchscreen display and radio frequency identification technology (RFID). While computer-assisted treatment of aphasia has been used since the 196
Situational knowledge in physics: The case of electrodynamics
Major difficulties for a novice physics problem solver are how to interpret new problems and how to combine information given in the problem with information already known. A domain expert, by contrast, has the knowledge to take full advantage of problem features at a glance. It takes a long period of practice to acquire such situational knowledge, and it would be desirable for this to be taught more effectively. As a first step, this requires information on how situational knowledge differs acr
Physics learning with a computer Algebra systems: Towards a learning environment that promotes enhan
To become proficient problem-solvers, physics students need to form a coherent and flexible understanding of problem situations they are confronted with. This is important both for solving problems and for interpreting solutions. Still, many students have only a limited representation of the problems they are working on. Therefore, we devised an instructional approach to promote students' understanding of these problems, and to support them in forming associations between problem features and so
Co-Lab, design considerations for a collaborative inquiry learning environment
Co-Lab is a learning environment for collaborative inquiry learning in which learners can experiment, make models, consult background information and discuss their findings. The complex learning processes in such an environment need to be supported by appropriate features in the software. In this paper we report on how, based on existing literature and specific user and usability studies, we developed a set of design guidelines that were implemented in the software.
Contextualizing Discussions in Distance Learning Systems
In distance learning systems, communication tools are rarely integrated into learning activities, which does not encourage their use. The main goal of our work is to mitigate this lack of integration. Our aim is to bring the discussion activities closer to the learning activities, i.e. to situations to which the discussions must ideally relate to in order to promote learning between students. Thus, we suggest two models of forum which are contextual and based on a structuring of discussions resp
Using Case-Based Reasoning in Instructional Planning.Towards a Hybrid Self-improving Instructional P
This paper presents a new approach, based on the Case-Based Reasoning technique, which is useful to enhance Intelligent Tutoring Systems with learning abilities. Case-Based Reasoning is a recent paradigm for problem solving that has an inherent learning capability. So we integrate a Case-Based Instructional Planner within existing Intelligent Tutoring Systems (ITS) to enhance the pedagogical component with learning capabilities. In this way, the enhanced tutors combine the Case-Based Instruction
