3 The purpose of writing
Writing reports and assignments can be a daunting prospect. This unit is designed to help you develop the skills you need to write effectively for academic purposes. You will learn how to interpret questions and how to plan, structure and write your assignment or report.
GasLab
This is a series of computer animations which demonstrate all the possible combinations of the ideal gas law or equation of state. Gases have various properties which we can observe with our senses, including the gas pressure, temperature, mass, and the volume which contains the gas. Careful, scientific observation has determined that these variables are related to one another and the values of these properties determine the state of the gas. In a scientific manner, we can fix any two of the fou
Northeastern Student-Athletes Post Strong Fall Semester Academic Performance
Northeastern University student-athletes continued a tradition of strong academic achievement during the fall 2010 semester, as 178 student-athletes earned a 3.25 grade-point average (GPA) or better, with seven earning a perfect 4.00 GPA.
The Lessons of 1704
In The Lessons of 1704, students learn the basic skills needed to do research and to "read" primary and secondary sources, to see what they can reveal about the cultural characteristics and attitudes of the English, French, and Native Americans in the Deerfield area in the late 17th and early 18th centuries. At the same time, they learn about the attitudes and behaviors of these three groups toward one another. Then, they use what they have learned to analyze the 1704 attack on Deerfield and the
Raid on Deerfield: the Many Stories of 1704
After several classroom discussions on anti-slavery issues, students will study the "American Anti-Slavery Almanac for 1838." The students will understand the importance and role of political cartoons during the anti-slavery movement. Students will observe and identify details in a political cartoon. Students will understand that there were people both in favor of and against slavery here in the North and how both sides are represented in the cartoon. Students will create their own anti-slavery
A Field Study of Interspecific Relationships
This exercise can be used to study population ecology, food webs and trophic levels. It is meant to give students a better understanding of the interrelatedness of organisms in a community by studying several common local relationships.
Introduction to Climate - Background Material
Climate is generally defined as average weather over a long period of time. A place or region's climate is determined by both natural and human-induced factors. Students can read an overview of Earth's climate and participate in activities which explain the following concepts: distinctions between weather and climate, variability of daily weather measurements compared to long-term climate data, how significant annual variability affects long-term climate averages, how Earth's climatic changes oc
A Holistic Approach to Teaching a Laboratory, Using Sea Urchin Development as an Example System
This exercise uses brainstorming, writing, and oral presentation techniques within the framework of a laboratory to illustrate the basic principles of early development. In groups, students learn how to identify a good model system (the sea urchin), isolate its gametes, mix some gametes from each sex, and study the ensuing processes of fertilization and development. After being introduced to the basic techniques, student groups design their own experimental approaches to further analyze these pr
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
ATP deficit in bipopulation tumour cord growth
Simulation of tumor cord growth where conversion of the tumor to glycolytic (anaerobic) metabolism takes place under hypoxia. This video shows evolution of the region where the aerobic cells suffer from hypoxia (ATP deficit) as well as the limit where the glycolytic cells start suffering too. This video reflects work in progress and may be different from the final results.
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
