Analysing the significance of problem solving expertise and computational tool proficiency in design
This paper presents a pilot study to analyze the role of problem solving expertise (PSE) and computational tool proficiency (CTP) of expert and novice architects in the ideation process within a distributed cognition environment. To analyze PSE, we studied the frequency of occurrence of unique problem solving tasks per limited commitment mode (LCM) revisit. We also devised a quantitative measure for analyzing CTP based on the frequency of unique and normally distributed modeling activities per d
Tracking Design Development through Decomposing Sketching Processes
We conducted a protocol study of the architectural sketching process. We decompose the process into process flows to explore the extent to which it expresses concept development in schematic and refined design phases. We track the development of design concepts in these phases by following the process flows of individual sketched strokes. We argue that each stroke drawn by the designer reveals a probability of an embedded concept, and that this concept is either promoted and propagated throughou
A Virtual Learning Environment for Doing Business on the Internet
The power of the new Communication and Information Technologies influences human life and economy so deeply that makes all of us learners both as individuals and members of (real or virtual) learning communities and learning organisations in a learning society. Looking back at the communication and information technology history we could clearly observe that the main attention of researchers and technologists has been gradually moved from hardware to software, next - to human-computer interface,
Basic Analysis: Introduction to Real Analysis
This free online textbook is a one semester course in basic analysis. These were my lecture notes for teaching Math 444 at the University of Illinois at Urbana-Champaign (UIUC) in fall 2009. The course is a first course in mathematical analysis aimed at students who do not necessarily wish to continue a graduate study in mathematics. A Sample Darboux sums prerequisite for the course is a basic proof course. The course does not cover topics such as metric spaces, which a more advanced course woul
Allometry: Size and its consequences or... Why aren't there 20 foot tall ants?
Evolution has resulted in changes in the sizes and forms of organisms. Everything about the biology of an animal, including its physiology, anatomy, and ecology, is influenced by its body size. Frequently there seem to be limits on the sizes that different organisms can attain, even when larger size might be thought to be evolutionarily advantageous. Often an increase or decrease in size is correlated with a change in proportions. Understanding the significance of a particular morphology or inte
Comparison of Approaches to a Multimedia Presentation
Two computer-based multimedia lecture presentations were developed using the same software but using two different approaches. Similar lecture material was used for both lecture presentations. Students found that there were considerable differences between the two lecture presentations. One lecture presentation was found to be very dynamic and interesting compared to the other. However, when videos showing applications of theory were supplied with the less interesting lecture presentation, stude
An Introduction to Plant Vascular Systems
As a laboratory exercise that uses scientific techniques to add an investigative component to study the vascular system of plants.
Developing Customized Instructional Software
Costs to faculty in time and costs for the purchase of software help inhibit widespread instructional computing. mpAuthor is an expensive program for DOS/IBM microcomputers; anyone able to use a word processor producing ASCII files can create menu-driven exercises. Several examples of its use are presented, including some to improve thinking and problem- solving skills. Strengths of the program include: minimal computer skills required (have students create exercises instead of a term paper or a
Control of Surface Exudation by Slugs
This experiment is meant to study water regulation in mollusks by observing the reaction of slugs, which are closely related to mollusks, to excess water.
Impact of Computer Aided Learning on Children with Specific Learning Disabilities
The Technology Initiatives Division of Azim Premji Foundation has launched programmes for use of computers in rural schooling. One such programme is Computer Aided Leaning (CAL) that envisages deployment of computers as a media to impact learning competencies and to create an attractive environment in the schools. The state government provides the computers in schools and the Foundation has developed required software content designed to aid classroom learning process in specific areas such as m
Internet Medieval Sourcebook
Historians teaching medieval history surveys almost always want to combine a textbook, a sourcebook, and additional readings. Textbooks, as an ever-evolving form, are probably worth the cost, but sourcebooks are often unnecessarily expensive. Unlike some modern history texts, the sources used for medieval history have been around a long time. Very many were translated in the 19th century, and, as a rapid review of any commercial source book will show, it is these 19th century translations which
Crystalluria and its possible significance. A patient-control study.
The significance of crystalluria in the diagnosis and prognosis of urolithiasis remains a controversial subject in the current urological literature. In this study, in addition to the standard urolithiasis clinical and biochemical work-up,routine urine microscopy was performed to study crystals in 1 fresh and 2 stored morning urine samples from 140 urinary stone patients and 42 controls. Crystalluria was more frequently detected in patients (9.3% of the fresh samples)than in controls (2%). Stori
1899 Baist Property Atlas
This 1899 Baist Property Atlas lists some of the buildings such as the English Hotel and the Indianapolis Power and Light Company located on the northwest and southwest quadrants of the Circle.
Archaeology as a Perspective on Sex and Gender in the Past
Description not set
Do you want to get more out of drama? This unit is designed to develop the analytical skills you need for a more in-depth study of literary plays. You will learn about dialogue, stage directions, blank verse, dramatic structure and conventions and aspects of performance.
In Search of Cosmic Rays
These interactive lessons teach about Cosmic Rays by emphasizing the mystery that Cosmic Rays presented to early scientists. The scientific inquiries and investigations that Cosmic Rays prompted are interesting and important to understanding the way science works. Cosmic Rays are now being studied at research sites around the world. Much has been learned from early experiments and even more is being discovered with modern experiments, but many questions have yet to be answered.
The is the study of how scarce resources are allocated to satisfy unlimited wants in a cultural context. Microeconomics is often defined as the study of individual agents' [persons, organizations, firms, markets] choices about the allocation of scarce goods and how these individual choices relate to the society made up of those individuals. The focus here is the use of technology and social interaction to coordinate individual action.
Apartheid protest at the South African Consulate, tape 2
Apartheid protesters gather in front of the South African Consulate at 100 Charles River Plaza in Boston. Mel King (political activist), Charles Yancey (Boston City Council) and Willard Johnson (Head, TransAfrica) demand to see Richard Blankstein (honorary consul to South Africa). Police officers bar entry to the building. Johnson announces that the protestors will ask for Blankstein's resignation from his post. He adds that they will ask Blankstein's law firm to sever ties with South Africa. Jo
This collection of activities and resources is a companion guide for the 15-minute film Defying genocide. The history of the Holocaust and the 1994 Rwandan genocide illustrate the entire spectrum of human behavior, from unimaginable evil to extraordinary goodness. Through a study of the Holocaust, Rwanda, and genocide, students learn that genocide occurs because individuals, organizations, and governments make choices to participate, resist, or turn away. Students can also see that at the same
Computer science is the study of computational systems and their use in representing important problems in science and society. Major topics include computational science, software systems, network systems, theory of computation, machine learning, and human-computer interaction.
