The document compares the obsolete overhead projector technology to the emerging interactive whiteboard technology. It notes that overhead projectors only allowed one-way information sharing from teacher to students, while interactive whiteboards enable two-way interaction between teachers and students. It also states that interactive whiteboards allow incorporation of richer multimedia content into lessons and provide increased flexibility for teachers to interact with students. The emerging technology of holograms is predicted to eventually replace interactive whiteboards by enabling even more immersive three-dimensional teaching experiences.

This session looks at applying the same principles and disciplines used in other areas of system development to tame the ever increasing complexity that has arisen from the maturity of the RDBMS. To show how easy it can be to apply TDD/Unit Testing to SQL development, part of the talk will involve coding up a procedure in a test-first manner using a freely available T-SQL based test framework.
Waltzing with Branches [Agile o/t Beach]Chris Oldwood
The use of branches within a version control system is a risk management technique. They are commonly used to minimise the risk of unanticipated side-effects when releasing critical changes to production, or to minimise the disruption to developer productivity when making changes to the base product. But branching is not the only means of managing risk and that is what this talk addresses – the forces that drives the use of branches, what are their problems and what are the alternatives.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
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.

Multimedia presentation:obsolete and emerging tech
1.
2. Obsolete Technology: Overhead Projector
▪ Device that allows users to project slides
or transparencies onto a board or screen
▪ To edit any of the information that was on
the transparency the teacher had to use
special pens that were made for use on
overhead transparencies
▪ Inability to support the features that
more modern technology users require
▪ Do not allow for much student interaction
with a lesson nor do they offer the ability
to offer multimedia experiences within a
lesson
▪ Teachers are required to stay with the
device during teaching; therefore,
reducing teacher interaction with students
3. Emerging Technology: Interactive Whiteboard
▪ A large interactive board that is hung from
the wall and attached to a computer and
projector
▪ Increased student’s ability to interact with a
lesson because the students can manipulate
information that is on the screen
▪ Allows teachers to move around the room as
they teach which increases the teacher’s
ability to interact with the students
▪ Allows the teacher to incorporate more
effective multimedia instructional experiences
▪ Requires less mess due to not having to use
specialty ink pens or transparencies

8. Science Fiction
Science fiction provides a vehicle that allows innovators to
imagine and grow. Dr. Thornburg (Laureate Education, 2014i)
describes science fiction as the stories that trigger the
imaginations of investors.
Overhead Projector
This type of
technology was never
seen in movies before
it was invented.
Interactive Whiteboard
Science fiction movies were filled
with touch screen devices before
the interactive whiteboard was
invented. The Sci-fi movie Minority
Report (2002), introduced
touchscreen devices before they
emerged.
9. Disruptive Technologies
A disruptive technology is a technology that displaces another technology. Thornburg
(Laureate Education, 2014a) defines a disruptive technology as new technology with
the same functionality of an existing technology. The new technology functions more
efficiently, and will obsolete the previous technology.
Interactive whiteboards changed
the way teachers taught in
schools. They replaced the
overhead projectors that had
limited capability. This new and
exciting equipment changed the
ways that students were
presented information.
10. Increasing Returns
Increasing returns is when two technologies emerge at around
the same time and one drives the other to extinction.
Overhead Projector
There was not another technology
tool that emerged at the same time
of the overhead projector.
Interactive Whiteboard
Interactive whiteboards have
consistently driven out the use of
overhead projectors to the point that all
they do is gather dust on shelves in the
back of media center closets.
11. Red Queens
Red queens is when there is a competition between technologies and
one is left behind.
Overhead Projector
When the overhead projector
emerged into classrooms they
were in competition with slide
projectors.
Interactive Whiteboard
There is presently competition
between the interactive
whiteboard and the document
camera.
12. Future of Emerging Technology
I believe that there will soon be a projector that will allow for 3D and/or holographic
images to be projected into the classroom. According to Kelly Walsh (2012), holographic
technology is the next step in this evolution – the use of holographic telepresence to
bring digital participants and remote location into the class in 3D. This type of
technology is still many years in our future; therefore, the interactive whiteboard will
be around for at least 5-10 more years.
Holograms will allow teachers to model and demonstrate a strategy without having to be
in a classroom. Holograms will allow educators to bring their content to life. Holograms
will make the use for overhead projectors, whiteboards, chalkboards, filming projectors,
digital and video tape players obsolete. Holograms may eventually replace interactive
whiteboards. A three-dimensional presence can enhance the learner instructional
experience.
13. Holographic
Technology
Enhances
Allows experts and facilitators
the ability to illustrate processes
live, and in person. Allows
instructors to deliver lectures to
multiple classrooms, any where,
simultaneously. Allows experts
to deliver a new dimension to
instructional content.
Rekindle
Ability to rekindle
pedagogical
practices that
promote cognitive
learning
Obsoletes
Need to use overhead projectors,
whiteboards, chalkboards, filming
projectors, digital and video tape
players, and possibly interactive
whiteboards
Reversal
Ability for teachers
to promote teacher
to student discourse
Holographic Technology Tetrad
14. Summary
There is an expectation for leaders in educational technology to be aware of emerging
technologies.
Creating a tetrad shows how new technologies emerge and how other technologies
become obsolete. Dr. Thornburg (Laureate Education, 2014f) points out that creating a
tetrad supports practitioners in being aware of how new technologies incorporate
creative processes into everyday life.
New technologies support learners and facilitates learning. As a futurist, it is important
to be aware, explain, and be able to demonstrate the significance of using an emerging
technology.
