Dog examination techniques
This presentation has been developed to introduce veterinary students to the process of carrying out a systematic physical examination in canine patients. It is designed to act as an introduction to these processes and procedures only, giving the students a framework from which to work as they develop and refine these skills throughout the veterinary course. Physical examination is a key skill which will be used throughout a veterinary surgeon's career and is a key determinant in selecting diag
Enabling Mobile Collaborative Learning through Multichannel Interactions
The work presented here shows an architecture to integrate multiple communication channels for a simple communication tool: a weblog. The motivation for this work is to enable learners to access learning services regardless of their situation. Indeed, in some cases the access to these services is quite hard because people are on the move or don't easily have access to an Internet connection. This article presents the different elements that fit into the architecture which lay the path for a rich
EyA system: Automated audio-video-slide recordings
We discuss on an innovative system developed in-house to archive and share scientific lectures carried out using modern presentations (PPT, PDF, animations, etc) or, alternatively, the commonly used traditional chalkboards found in classrooms. The system -named "Enhance your Audience" (EyA), allows to widening the audience for such activities with little efforts. The technologies employed are low-cost.
The methodical approach to e-portfolio content formation
The paper develops a methodical approach to e-portfolio content formation. It includes several positions: application e-portfolio for different users category; substantiation of criteria for e-portfolio formations; design of curriculum and materials structure, which adequate to criteria set; developing complex project for realizing practical competences.
Graphical Jogthrough: expert based methodology for user interface evaluation, applied in the cas
Walkthrough and Jogthrough techniques are well known expert based methodologies for the evaluation of user interface design. In this paper we describe the use of Graphical Jogthrough method for evaluating the interface design of the Network Simulator, an educational simulation program that enables users to virtually build a computer network, install hardware and software components, make the necessary settings and test the functionality of the network. Graphical Jogthrough is a furth
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.
Efficient Embedding of Information and Knowledge into CSCL Applications
This study aims to explore two crucial aspects of collaborative work and learning: the importance of enabling CSCL applications, on the one hand, to capture and structure the information generated by group activity and, on the other hand, to extract the relevant knowledge in order to provide learners and tutors with efficient awareness and support as regards collaboration. To this end, we first identify and define the main types of information generated in online group activity and then propose
Hypermedia as a means for learning and for thinking about learning
This paper is about the design and realization of an experimentation with a hypermedial system, IPER-3, facing the three ‘classical’ problems in the history of mathematics (trisection of the angle, quadrature of the circle, duplication of the cube) and some issues which have developed around them. The aim of the work is to study the opportunities provided by hypermedial systems in dealing with topics of interest for the training of teachers and/or for class work, exploiting the possibility o
The role of interactive visualizations in the development of concepts of logic.
The main objective of the experiments described in this paper is to examine whether instructional variables often used in learning empirical sciences can also be used to facilitate the development of knowledge and skills in the formal sciences, particularly in learning logic. In learning empirical sciences, many positive effects have been reported which can be accounted for by the use of visualisation techniques, multiple representations and possibilities for the learners to interact with repres

A methodological note on modeling the effects of race: the case of psychological distress
Psychological distress is an important indicator of the mental well-being of the population. Findings regarding racial differences in distress are inconclusive but may represent an important pathway through which disparities exist across a number of physical health outcomes. We used data from the 1994 Minority Health Survey, a nationally representative multiracial/ethnic sample of adults in US households, to examine racial/ethnic differences in psychological distress (n = 3623). Our primary stud
Wetting on flexible substrates: a finite element formulation
Wetting is an important phenomenon in industrial applications such as coating industry as it could affect the coating uniformity and production rate. In modeling dynamic wetting on rigid solids, one of the challenges is to relieve the singularity in the viscous stress arising at the dynamic contact line due to double valued velocity. The singularity arising at the contact line is a mathematical singularity and not a physical singularity and hence, needs to be relieved. There are several models t
Geometric Methods in Structural Computational Biology
This course is a short series of lectures on Structural Computational Biology, with an emphasis on geometric algorithms. Topics covered include basic data structures for modeling proteins; kinematics and inverse kinematics of protein chains; distance measures and alignment algorithms for protein structures; motif finding for the functional annotation of proteins; the application of robotics-derived methods to problems in protein modeling; and protein-ligand docking. The development of this cours
Techniques for Studying Materials: Microstructural Examination
This set of animations consists of interactive phase diagrams of Fe-C, grey cast iron, white cast iron, alpha brass and alpha-beta brass. From TLP: Microstructural Examination
Forensics in the classroom
This site uses crime scene scenarios to introduce concepts of biology, chemistry, and physics in a way designed to excite interest in the applications of forensic investigations. Students conduct a variety of experiments including paper chromatography analysis, hair analysis, pH testing, fingerprinting, and handwriting analysis to experience forensic science technology. The site is a collaboration between the American Academy of Forensic Sciences and Court TV designed for middle and high school

Evaluating cardiac gene expression in maternal phenylketonuria offspring
Maternal phenylketonuria (MPKU) is a teratogenic syndrome, caused by development of offspring in a uterine environment made toxic by the metabolic imbalance of PKU. The birth defects resulting from untreated MPKU include microcephaly with concomitant mental retardation, growth retardation, and congenital heart defects. Congenital heart defects have been identified and characterized in MPKU offspring, using the BTBR-PAHenu2 mouse MPKU model. Subsequently, this mouse model was used to start invest
