The document provides an overview of activity diagrams, including what they are, their purpose, how to draw them, where to use them, and how they differ from flowchart diagrams. Activity diagrams illustrate the flow of activities from one to another and can show parallel, branched, and concurrent flows. They are used to model workflow, business requirements, and the functionalities and systems within an application. Key elements of activity diagrams include activities, flows, decisions, forks, and swimlanes.
Activity Diagram Model An activity diagram visually presents a series of actions or flow of control in a system similar to a flowshart or a data flow diagram. Activity diagrams are often used in business process modeling.

UML stands for Unified Modelling Language.
UML is a standard language for specifying, visualizing, constructing, and documenting a system in which software represents the most significant part.
UML is different from the other common programming languages like C++, Java, COBOL etc.
UML is a pictorial language used to make software blue prints.
UML can serve as a central notation for software development process. Using UML helps project teams communicate, explore potential designs, and validate the architectural designs of software.
UML diagrams are made using notation of things and relationships.
The building blocks of UML can be defined as:
Things
Relationships
Diagrams
Things: Things are the most important building blocks of UML. Things can be:
Structural
Behavioral
Grouping
Annotational
The Structural things define the static part of the model. They represent physical and conceptual elements. Following are the brief descriptions of the structural things.
Class: Class represents set of objects having similar responsibilities.
Interface: Interface defines a set of operations which specify the responsibility of a class.
Collaboration: Collaboration defines interaction between elements.
Use case: Use case represents a set of actions performed by a system for a specific goal.
Component: Component describes physical part of a system.
Node: A node can be defined as a physical element that exists at run time.
A behavioral thing consists of the dynamic parts of UML models. Following are the behavioral things:
Interaction: Interaction is defined as a behavior that consists of a group of messages exchanged among elements to accomplish a specific task.
State machine: State machine is useful when the state of an object in its life cycle is important. It defines the sequence of states an object goes through in response to events. Events are external factors responsible for state change.

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.

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.

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

PART 1: What is Activity
Diagram
3. Activity diagram illustrate 3 flow methods, as follows:
Parallel
Branched
Concurrent
1. Activity diagram describe the dynamic aspects of the system. Activity
diagram is basically a kind of flowchart to represent the flow from one
activity to another activity, but not a flowchart.
2. A kind of flow chart to represent the flow of one activity to another
activity but not a flowchart
• This means that two tasks can literally run at same time
• This means having a task and that task is been evaluated in another
task A or task B
• This means when two or more task can start, run, and complete in
overlapping time period.

Purpose of Activity Diagrams
1. Activity is a particular operation of the system. Activity diagrams
are not only used for visualizing the dynamic nature of a system,
but they are also used to construct the executable system by using
forward and reverse engineering techniques. The only missing thing
in the activity diagram is the message part.
2. The purpose of an activity diagram can be described as −
• Draw the activity flow of a system.
• Describe the sequence from one activity to
another.
• Describe the parallel, branched and concurrent
flow of the system.

PART 2: How to Draw an Activity Diagram?
1. Before drawing an activity diagram,
we must
have a clear understanding about the
elements
(notations) used in activity diagram.
1. Notations
• Initial state start point
A small filled circle with an arrow.
It defines the initial state or start point for
any activity diagram
• Activity or action state
An action state represents the non-interruptible action
of objects. You can draw an action state in SmartDraw
using a rectangle with rounded corners.
Activity
• Action flow Action flows, also called edges and paths, illustrate the transitions
from one action state to another. They are usually drawn with
an arrowed line.
Before drawing an activity diagram, we should
identify the following elements:
• Activities . Association
• Conditions, and Constraints

How to Draw an Activity Diagram?
• Object flow
Object flow refers to the creation and modification of objects
by activities. An object flow arrow from an object to an action
indicates that the action state uses the object.
Activity
Class/object
• Decisions and Branching
A diamond represents a decision with alternate paths.
When an activity requires a decision prior to moving on
to the next activity, add a diamond between the two
activities
• Guards
.
In UML, guards are a statement written next to a
decision diamond that must be true before moving
next to the next activity. These are not essential, but
are useful when a specific answer, such as "Yes,
three labels are printed," is needed before moving
forward

Synchronization A fork node is used to split a single incoming flow into multiple
concurrent flows. It is represented as a straight, slightly thicker
line in an activity diagram.
Time Event
This refers to an event that stops
the flow for a time; an hourglass
depicts it.
Merge Event
A merge event brings together
multiple
flows that are not concurrent.

Sent and Received
Signals Signals represent how activities can be modified from
outside the system. They usually appear in pairs of sent
and received signals. For example, an authorization of
payment is needed before an order can be completed.
Interrupting
Edge
An event, such as a cancellation, that interrupts
the flow denoted with a lightning bolt.
Swimlanes group related activities into one column.

3. Following is an example of an activity diagram for order
management system. In the diagram, four activities are identified
which are associated with conditions. One important point should be
clearly understood that an activity diagram cannot be exactly matched
with the code.
Following diagram is drawn with the four main
activities
• Submit student details.
• Check attendance and yearly income.
• Approve or decline.
Final State or End
Point An arrow pointing to a filled circle nested inside
Another circle represents the final action state.
Interrupting
Edge
An event, such as a cancellation, that interrupts
the flow denoted with a lightning bolt.

Where to Use Activity Diagrams?
1. Activity diagram is suitable for modeling the activity flow of the
system. An application can have multiple systems. Activity
diagram also captures these systems and describes the flow
from one system to another. This specific usage is not available
in other diagrams. These systems can be database, external
queues, or any other system.
2. This diagram is used to model the activities which are nothing
but business requirements. The diagram has more impact on
business understanding rather than on implementation details.
Activity diagram can be used for:
• Modeling work flow by using activities.
• Modeling business requirements.
• High level understanding of the system's
functionalities.
• Investigating business requirements at a later
stage.
