Tracheid Length Measurement in Selected Conifer Species
This exercise illustrates the techniques for macerating wood and staining, mounting, and measuring tracheids. Mean tracheid length is different in different species of conifers; therefore, this laboratory can be expanded into a larger scale comparative measurement exercise.
Use PCR and a Single Hair to Produce a "DNA Fingerprint"
As a former student once commented, "PCR is the sliced bread of molecular biology". Polymerase Chain Reaction (PCR) is a process that allows an investigator to amplify a portion of a single piece of DNA into over one billion copies. We have used PCR with our Introductory Biology students to generate a simple "DNA fingerprint". This exercise will outline all the steps required to generate a DNA fingerprint for each student during two lab meetings. This article covers the background information co
Therapod Fossil Hunt Dispatch
This five-part online article reports on the finding of a dromaeosaur fossil, the best specimen to date to show that feathers existed long before modern birds and flight. Part 1 includes: It All Started with Feathers, A Path Shrouded in Mystery, and International Collaboration. Part 2 has The Short Email and A Coat of Feathers. Part 3 includes: An Initial Hypothesis and Is It Authentic? The Analysis Begins. Part 4 has The Examination and Description Marathon, A Feathered What?, and Feathers, Fea
Genetic Literacy: Meeting the Teaching Challenge
This online article, from the museum's Musings newsletter for educators, provides insight into teaching genetics and building genetic literacy. It looks at ways that teachers can: build their own knowledge base stay abreast of the wave of new information about genetics give their students the tools and techniques to make their way in the genomic age.
Empirical Research Methods in Software Engineering
This course will explore the role of empiricism in software engineering research, and will prepare students for advanced research in SE by examining how to plan, conduct and report on empirical investigations. The course will cover all of the principal methods applicable to SE: controlled experiment, case studies, surveys, archival analysis, action research and ethnographies, and will relate these methods to relevant metatheories in the philosophy and sociology of science. The course will critic
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
Aimed at healthcare practitioners, this learning object describes why hand hygiene is so important in a healthcare setting, then uses video clips to demonstrate correct, and incorrect, hand washing techniques.

These interactive (Flash) online exercises that help students to use and understand decay curves. All questions must be answered correctly before the student can ...
Artificial Intelligence: Introduction to Robotics
The purpose of this course is to introduce you to basics of modeling, design, planning, and control of robot systems. In essence, the material treated in this course is a brief survey of relevant results from geometry, kinematics, statics, dynamics, and control. The course is presented in a standard format of lectures, readings and problem sets. There will be an in-class midterm and final examination. These examinations will be open book. Lectures will be based mainly, but not exclusively, on ma
Artificial Intelligence: Natural Language Processing
This course is designed to introduce students to the fundamental concepts and ideas in natural language processing (NLP), and to get them up to speed with current research in the area. It develops an in-depth understanding of both the algorithms available for the processing of linguistic information and the underlying computational properties of natural languages. Wordlevel, syntactic, and semantic processing from both a linguistic and an algorithmic perspective are considered. The focus is on m
Linear Systems and Optimization: The Fourier Transform and its Applications
The goals for the course are to gain a facility with using the Fourier transform, both specific techniques and general principles, and learning to recognize when, why, and how it is used. Together with a great variety, the subject also has a great coherence, and the hope is students come to appreciate both.

"Experimental Microbial Genetics, Fall 2008"
" In this class, students engage in independent research projects to probe various aspects of the physiology of the bacterium Pseudomonas aeruginosa PA14, an opportunistic pathogen isolated from the lungs of cystic fibrosis patients. Students use molecular genetics to examine survival in stationary phase, antibiotic resistance, phase variation, toxin production, and secondary metabolite production. Projects aim to discover the molecular basis for these processes using both classical and cutting
"Angles, Spring 2010"
" Angles is an annual online magazine of exemplary writing by students in four foundational writing courses at MIT: 21W.730: Writing on Contemporary Issues; 21W.731: Writing and Experience; 21W.732: Science Writing and New Media; and 21W.734J: Writing About Literature. In these classes, students learn to read more critically, to address specific audiences for particular purposes, to construct effective arguments and narratives, and to use and cite source material properly.
