This course introduces cryptography by addressing topics such as ciphers that were used before World War II, block cipher algorithms, the advanced encryption standard for a symmetric-key encryption adopted by the U.S. government, MD5 and SHA-1 hash functions, and the message authentication code. The course will focus on public key cryptography (as exemplified by the RSA algorithm), elliptic curves, the Diffie-Hellman key exchange, and the elliptic curve discrete logarithm problem. The course concludes with key exchange methods, study signature schemes, and discussion of public key infrastructure. Note: It is strongly recommended that you complete an abstract algebra course (such as the Saylor FoundationĺÎĺ_ĺĚĺ_s MA231) before taking this course. Upon successful completion of this course, students will be able to: explain how symmetric and asymmetric key ciphers work; list and define cryptographyĺÎĺ_ĺĚĺ_s goals; list and define the most common classical ciphers; explain the workings of mechanical ciphers Enigma and Lorenz; describe the principles of substitution-permutation networks; describe the algorithms for data encryption and the advanced encryption standard; describe and use the MD5 and SHA-1 hash functions; explain the idea behind public key cryptography; use the RSA cryptography system by applying it to practical problems; test whether the large integer is prime with the mathematical tools presented in this course; define the elliptic curve and use it in cryptography; explain the Diffie-Hellman key exchange; describe the most common signature and autokey identity schemes; describe the conceptual workings of public key infrastructure. This free course may be completed online at any time. (Computer Science 409)

This research article provides the details of a current immunotherapy study performed by scientists at MIT. Immunotherapy is a relatively new and very promising cancer treatment that is now a focus of many cancer research labs. The article discusses what immunotherapy is, how T cell activation works, and how the treatment has eliminated some tumors in mice. As an interactive activity, students can practice making annotations in the margins of the article to check for understanding. Overall, students who read and dissect this article are learning how to comprehend complex biomedical research studies. As a supplemental activity, teachers can distribute the worksheet quiz posted in WISELearn. This set of questions (true/false, fill in the blank, multiple choice, short answer) assesses the students' comprehension levels of the current MIT immunotherapy research. An answer key is provided. The skills learned from investigating this article can hopefully be used to investigate other current biomedical research for human diseases and disorders.

This module of the course focuses on educative assessment. Educative assessment is designed to provide educators and learners with feedback to improve their work. In this module you will learn the UbD-DI principles of authentic assessment and understand how UDL integrates with them. You will then use a protocol to generate valid assessment criteria based on a review of student work samples.

This Business English lesson plan on cybersecurity has been designed for business professionals or other adults and young adults at an intermediate (B1/B2) to advanced (C1/C2) level and should last around 45 to 60 minutes for one student.

The American Indian Studies Program exists primarily to assist with the implementation of the curricular requirements in the areas of American Indian history, culture, and tribal sovereignty. The program is also responsible for American Indian Language and Culture Education.

SHEG Lesson on the Declaration of Independence.
Central Historical Question:
Why did the Founders write the Declaration of Independence?

This activity is a classroom experiment where students make observations, state hypothesis and carry out an investigation to draw conclusions.

This activity is a lab where students will design an experiment dealing with one of the five senses. Students will collect data outside of class, write a formal lab write up as well as a group presentation on their findings.

Students will design, build and test a hot air balloon of their choosing. Students will construct and test components in order find three component optimum design features for final assembly.

Students will work in teams to design and market a recyclable celebrity outfit. The first part involves researching the celebrity. The second aspect is to actually design the recyclable outfit on an in-class model. The third part is to create a video that replicates a celebrity interview on the red carpet; which allows the designers to describe the detail that was put into the outfit, and allows the model to describe why the eco-friendly outfit is popular/needed.

This activity is a lab where students design an experiment to test the rate of photosynthesis. Students will analyze data,write a report using the scientific method, and apply results to current environmental issues.

This lesson unit is intended to help teachers assess how well students are able to: Select appropriate mathematical methods to use for an unstructured problem; interpret a problem situation, identifying constraints and variables, and specify assumptions; work with 2- and 3-dimensional shapes to solve a problem involving capacity and surface area; and communicate their reasoning clearly.

This activity is an inquiry lab where students are challenged to create a slow moving and fast moving plane and measure the speed.

This is a lab activity where students observe the relationship between pressure and volume. They use their data to determine the formula for Boyle's Law.

In this activity, students will investigate how much chlorophyll is in olive oil using a Varnier Spectrometer. Students will measure and analyze the visible light absorbance spectra of three standard olive oils obtained from any supermarket: extra virgin, regular, and light.

This activity is an introduction to population sampling techniques. Students' will identify weaknesses and strengths of a variety of techniques and determine the best applications of the various methods identified.

This activity is an inquiry lab where students observe the effects of temperature change on nitrogen dioxide gas, a common component of polluted air, to determine its color.

A multimedia 1st-year German language program based on videos of native speakers and the UT Summer Program in WŸrzburg, Germany. The online textbook includes recorded vocabulary, phonetics lessons, an online grammar component, online comparative polls and internet writing activities.

Students are asked to compare two similar businesses in an effort to differentiate the business' target markets. Students will answer a series of questions about the business in order to create a customer profile. Students will utilize their customer profile to determine how and where that business should advertise. This helps students see that all decisions relate back to a business' target market.

This lesson unit is intended to help you assess whether students recognize relationships of direct proportion and how well they solve problems that involve proportional reasoning. In particular, it is intended to help you identify those students who: use inappropriate additive strategies in scaling problems, which have a multiplicative structure; rely on piecemeal and inefficient strategies such as doubling, halving, and decomposition, and have not developed a single multiplier strategy for solving proportionality problems; and see multiplication as making numbers bigger, and division as making numbers smaller.
