Interactive technologies are “methods, tools or devices that allow various entities (individuals, machines, or organizations) to engage in mediated communication to facilitate the planning and consummation of exchanges between them.” (Varadarajan et al., Citation2010, p. 97). In the present paper, we focus on interactive technologies whose communicating entities are team members and which vary in their degree of interactivity (Bolton & Saxena-Iyer, Citation2009). At the low end of interactivity, interactive technologies can include static websites, whereas at the high end of interactivity, they can include robots or AI-powered interlocutors. Such interactive technologies are increasingly being applied to assist team interactions (DeCostanza et al., Citation2018). For instance, video conferencing tools, such as Zoom, Skype, or Cisco Webex, are used by more than 78% of corporate companies (Czmut, Citation2021). This illustrates the strong integration of interactive technologies and teamworkFootnote2 in today’s organizational world.
Although technology has become ubiquitous in our everyday lives, encompassing both leisure and work activities, there is a clear interest in designing and implementing technologies for teams in the work context. It all started with computer labs in schools, providing students, and even some teachers, access to computers for the first time in their lives. Today, computers and the use of technology have become an integral part of people’s everyday lives, with pre-school learners being exposed to technology even before they master the basic skills of reading, writing and arithmetic.
The introduction of the interactive whiteboard in the classroom has since resulted in an era in which the use of technology was literally moved to the front and centre of the learning environment, with many teachers and educators grasping the opportunity to enhance teaching by effectively using it as an interactive, real-time projection device, resulting in higher levels of student participation and concentration.
A concept that was and is unfortunately overlooked is that the technology (hardware) is, ultimately, merely a means to an end. External school funding projects allowed schools to implement interactive whiteboard solutions in many classrooms and, due to the focus placed on the acquisition of the tangible items, the concept of such devices simply being a means to an end was overlooked by many. This resulted in a significant number of interactive whiteboards either being used as projection surfaces only, or not used at all.
Apart from the lack of basic and ongoing professional development, the technology has been regarded as finicky and problematic, often requiring constant re-calibration, the use of external light sources which impact viewing quality, issues around incorrect software drivers and more. Many of these issues arose as the result of
7. SPARK PLUG
Rationale
The Sparking plug is specially
constructed metal plug, screwed
into the combustion chamber of a
gasoline engine for ignition
purpose.

8. Desired Learning Objectives(DLOs)
At the end of this lesson the students will be able to:
1-Enlist the main parts of Spark plug by consulting handouts
in 02 minutes.
2- Classify the Spark plug in respect of structure in 03
minutes correctly.

SPARK PLUG
9. SPARK PLUG
Definition
It is a device used in internal combustion engine to produce a
spark which ignites the air fuel mixture in the combustion chamber

11. Parts of Spark Plug
The Spark plug is made of
three main parts.
The Central Electrode
The Body
The Insulator

SPARK PLUG

SPARK PLUG
Parts of Spark Plug
1. Centre Electrode
The high-tension current from the coil or magnet is delivered to the central
electrode at the correct interval and spark jumping from the electrode to the body
of the plug
2. Body Or Earth Electrode
The body is a made off steel with hexagon outside to fit the spanner a
thread at lower end to the screw into the cylinder head outside welded to its lower
end is the earth electrode
15. Classification of Spark Plug
A sparking plug is classified by the
length of its threaded portion.
The diameter is stated in millimeter and
the length in inches.
15
SPARK PLUG
16. Diameter
The majority of vehicle used 14 mm plug while 18 mm
plug used mainly on the engine of ground equipment
Length of threated portion
This length termed as reach (short , medium and long). Ensure
the correct reach of plug is fitted

SPARK PLUG
Classification of Spark Plug
17. Length
If a shorter reach of plug is fitted the spark will occur in
the pocket ,so slowing combustion and causing the
uncovered threads to become burnt. If a too long reach plug
is fitted it will probably cause damage to piston

Classification of Spark Plug
19. Heat Range
A Spark plug must dissipate enough heat so that the electrode do not over
heat , there by causing pre ignition, and also retain enough heat oil adhering to the
electrode is burnt off before it can bridge the air gap
Hot or Soft Plug
Plug which tend to retain their heat and used on low speed cold running
engine
19
SPARK PLUG
20. Medium Spark Plug
Used on medium temperature engine
Cold or Hard Plug
Plug which can dissipate their heat quickly used on fast high compression
engines.
