This document discusses algorithms, flowcharts, pseudocode, and decision structures. It begins by defining algorithms and their purpose in problem solving. It then explains flowchart symbols and how to represent algorithms visually using flowcharts. Several examples are provided of writing pseudocode, detailed algorithms, and corresponding flowcharts to solve problems. The document also covers decision structures like if-then-else statements and relational operators. It provides examples of algorithms using nested if statements. Finally, it presents an example of determining an employee bonus based on overtime worked and absences.
To understand algorithm and flowchart, it is better to refer this Slideshare that I have created. I have thoroughly presented the key points that make easy in remembering what algorithm and flowchart is. The slide is really simple and wonderful to use it for a quick reference.

The systems development life cycle (SDLC), also referred to as the application development life-cycle, is a term used in systems engineering, information systems and software engineering to describe a process for planning, creating, testing, and deploying an information system.
Registers are temporary storage area for instructions or data. They are not a part of memory; rather they are special additional storage locations that offer the advantage of speed.
Computer software or simply software is a program that enables a computer to perform a specific task as oppose to the physical components of the system (i.e. hardware).
All information in a file is always in binary form or a series of ones and zeros. A document includes any file you have created. It can be a true text document, sound file, graphics, images, or any other type of information the computer can create, store, or size from the internet.

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
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.

2. LEARNING OUTCOMES
At the end of the lesson, I should be able to:
a. -Define algorithm, Pseudo codes and flowchart
b. -State characteristics of Algorithms
c. -Outline functions of Algorithm
d. -Write algorithm for solving a given problem
e. -Flowchart symbols and their uses
f. -Translating algorithms to flowchart programs
g. -Draw flowcharts for solving given problems
3. ALGORITHMS AND FLOWCHARTS
A typical programming task can be divided into two
phases:
Problem solving phase
produce an ordered sequence of steps that describe
solution of problem
this sequence of steps is called an algorithm
Implementation phase
implement the program in some programming
language
4. STEPS IN PROBLEM SOLVING
1. First produce a general algorithm: (one can
use pseudo code)
2. Refine the algorithm successively to get
step by step detailed algorithm that is very
close to a computer language.
3. Pseudo code is an artificial and informal
language that helps programmers develop
algorithms. Pseudo code is very similar to
everyday English.
5. PSEUDOCODE & ALGORITHM
1. Example 1: Write an algorithm to determine a
student’s final grade and indicate whether it is
passing or failing. The final grade is calculated as
the average of four marks.
6. PSEUDOCODE & ALGORITHM
Pseudo code:
1. Input a set of 4 marks
2. Calculate their average by summing and
dividing by 4
3. if average is below 50
Print “FAIL”
else
Print “PASS”
8. THE FLOWCHART
A Flowchart is a graphical representation of the sequence
of operations in an information system or program.
Flowchart Characteristics:
1. shows the sequence of instructions in a single program or
subroutine
2. shows logic of an algorithm from start to finish
3. emphasizes individual steps and their interconnections
4. control flow from one action to the next
5. Different symbols are used to draw each type of flowchart
6. The start symbol indicates the beginning of a program
7. The end symbol indicate the end of a program.
9. FLOWCHART SYMBOLS
Oval
Parallelogram
Rectangle
Diamond
Hybrid
Name Symbol Use in Flowchart
Denotes the beginning or end of the program
Denotes an input operation
Denotes an output operation
Denotes a decision (or branch) to be made.
The program should continue along one of
two routes. (e.g. IF/THEN/ELSE)
Denotes a process to be carried out
e.g. addition, subtraction, division etc.
Flow line Denotes the direction of logic flow in the program
