June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Unit 8 - Information and Communication Technology (Paper I).pdfThiyagu K
This slides describes the basic concepts of ICT, basics of Email, Emerging Technology and Digital Initiatives in Education. This presentations aligns with the UGC Paper I syllabus.
1. Pre-lab research and observations
The table below lists the most common types of organic
compounds found in living organisms. For each type of
organic compound, give 1 or 2examples and describe one
characteristic, e.g. whether it is greasy, whether you find a lot
of it in meat or potatoes, etc.
3. Test for lipids
1. If a food that contains lipids is put on brown paper, it
will leave a spot that lets light through. To test for
lipids, divide a piece of a brown paper bag into 5
sections. Label the sections "vegetable oil", "glucose",
"starch", "powdered egg whites", and “water”.
1. In each section, rub a small amount of the substance
onto the brown paper. With a paper towel, rub off any
excess that may stick to the paper.
2. Set the paper aside until the spots appear dry—about 10
minutes.
See the following slide for an image of the set up
5. Test for glucose
1. Obtain 5 containers labeled: "vegetable oil", "glucose", "starch",
"egg whites", and “water”.
1. For each container, add about 2 ml of water to each container
using a dropper pipette (1 full dropper = 1 ml of water). Stir the
contents of each container to mix the substance with the water.
1. To test for glucose you will use a test strip with an indicator pad
that changes color in the presence of glucose. Prepare a piece of
paper with the name of each substance and a place to put the
glucose test strip you have used to test that substance. Dip one
test strip into each sample for 1-2 seconds. Remove the strip, put
it in the appropriate spot on your labeled paper, and wait 3
minutes.
See the following slide for an image of the set up
7. Test for carbohydrates
1. You must wear goggles to protect yourself.
2. To test for starch you will use iodine as an
indicator. In the presence of starch, iodine will
change color from yellow-brown to blue-black.
Add 5 drops of iodine solution to each container.
Stir the contents of each container.
3. CAUTION: Be careful when handling
iodine; it can stain hands and clothing.
8. Test for proteins
1. You must wear goggles to protect yourself.
2. Get 5 new container labeled "vegetable oil", "glucose",
"starch", "egg whites", and “water”.
3. Add about 2 ml of water to each container. Stir the contents
of each container to mix the substance with the water.
4. To test for protein you will use Biuret reagent as an
indicator. Biuret reagent turns from blue to purple in the
presence of protein. Add 20 drops of biuret reagent to each
container. Stir the contents of each container.
5. CAUTION: Biuret reagent contains sodium
hydroxide, a strong base. Be very careful not to
splash or spill any. If you splash any reagent on
yourself, wash it off immediately with water. Call
your teacher for assistance.
10. Put in large trash can Clean/return
Food containers and
lids

11. Day 1 discussion questions
be prepared to share your answers
1. Compare your results with your predictions in your
hypothesis section? Were there any differences?
What were they?
2. Did your starch sample test positive for glucose?
Why do you think that is?
3. Beans are a part of a plant that contains a tiny plant
embryo. Beans are rich in fats, sugar, proteins, and
starches. Explain why it would be important to
have all those molecules in a bean.
