The optical microscope, The functions of a light microscope is based on its ability to focus a beam of light through, which is very small and transparent, to produce an image.
A microscope is an instrument used to observe very small organisms i.e. microorganisms. The microscope provides magnification and resolution which makes the image enlarged and fine. There are different types of microscopes ranging from simple to compound microscopes.
Microscopy is the technique of using microscopes to observe and analyze objects that are too small to be seen by the naked eye. Microscopes are instruments that magnify and resolve the details of objects, allowing scientists and researchers to study the structure, composition, and behavior of materials and specimens at a microscopic level

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

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

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.

2. Tools of the Biologist
2. Microscope
-before microscope, no one knew about
microbial world
-Leeuwenhoek perfected lenses
-Must be carried properly at all times
-Very expensive to replace
-We will use light microscopes, block light
source and image disappears
4. Important properties of
Microscopes
1. Magnification- the power of the
microscope to enlarge the image of an
object
2. Resolution- the power of the
microscope to show detail clearly
5. Compound Light Microscope Parts
and Function
1. Ocular (eyepiece)- part you look through
-contains lenses that contribute to total
magnification
-power of 10x (magnifies 10 times)
6. Microscope Parts and Function
2. Body tube- hollow tube that keeps the
lenses of the ocular and objectives at a
set distance
3. Nosepiece- holds objectives
7. Microscope Parts and Function
4. Objectives- contain lenses that contribute
to total magnification
Magnification formula- calculate total
magnification
Total mag. = ocular power X objective power
8. Total Magnification
Ocular Objective
10x red 4 = 40x
10x yellow 10 = 100x
10x blue 40 = 400x
*microscopes we use are parfocal- can
switch b/t lenses without much adjusting
**only use lens paper to clean objectives
9. Microscope Parts and Function
5. Arm- supports body tube
6. Base- supports entire microscope
(when carrying, keep hand back on base
because lamp will be hot!)
7. Stage- tray-like structure that supports
specimen/slide over stage opening
10. Microscope Parts and Function
8. Stage Clips- keep specimen/slide tight
against stage
9. Stage Opening- allows light to pass
through/around specimen
10.Diaphragm- controls amount of light that
reaches your eye
11. Microscope Parts and Function
11. Light source- provides light to create the
image that you see
12. Coarse adjustment- larger knob, that
moves 1 of 3 structures (body tube, stage,
or nosepiece) and allows for rough focus
12. Microscope Parts and Function
13. Fine Adjustment- smaller knob, moves
the objectives slightly and allows for fine
focusing
13. Microscope Classifications
• Based on how image is created
1. Light Microscope
-uses light to create specimen image
-lenses are glass or plastic
-magnification and resolution are good
(2,000x)
14. Benefits of Light Microscopes
• Smaller portable
• Cost effective
• Easy specimen prep (live specimens can
be used)
• Training simple/ user friendly
• Can see microscopic items
15. 2 Types of Light Microscope
1. Simple- Has one lens
Ex: magnifying glass, Leeuwenhoek’s
microscope
2. Compound- Has 2 or more lenses
Ex: High school Biology microscope
(more lenses create better image and
better resolution)
19. The Cell Theory
Development
1. Leeuwenhoek- First to see living cells
2. Hooke- coined the term cell while
viewing cork
3. Lamarck Put out publications that
4. Mohl indicated the cellular nature
5. Meyen of life (None of these men
given credit for cell theory)
20. Cell Theory Scientists
1. Schleiden (German)
-Botanist
-determined that all plants and their parts
(roots, stems, leaves, etc) are composed
of cells– plant cell drawing
21. Cell Theory Scientists
2. Schwann (German)
-Zoologist
-Determined that all animals and their
parts are composed of cells (tougher to
convince people of this)
Reasons for this:
1. Rounded shape- most “cells” were
square
2. No cell wall
22. Cell Theory Scientists
Animal cell drawing
Reason Schwann was successful was
because there was a nucleus present in
animal cell as well
23. Cell Theory Scientists
3. Virchow (German)
-Doctor
-determined that all cells come from pre-
existing cells
24. The Cell Theory
1. All living things are composed of cells
2. Cells reproduce or come from pre-
existing cells via cell division (mitosis)
3. Cells are the basic units of life or cells
are the smallest form of life
Possible essay: explain why cells are
smallest life forms
