1. Learning Conditions
1.1.1. Trainee :
There are 12 Trainees in the class and each Trainee has Electronics diploma Certificate . Also
their age for between 23 and 27 years. The Trainees come from different city for example
Al-Riyadh and AL-medina on the other hand the levels of the understanding are different,
some of them smart and they can get the knowledge fast and clear, but the other get slow , and
that make the Trainer work hard to help them to understand the subject very well , in the
classroom the Trainees must bring the book and pen also they must wear the uniform and
respect the Trainer also they must come to class on time. Finally the Trainees are friendly and
they like to work together and they are helpful .
1.1.2 .Classroom :
I will present my lesson at the TTC in classroom No4.205 at the EL building. This classroom
is equipped very well. The level of lighting is enough for teaching. Also, the classroom has a
nice air-conditioning system. Furthermore, the classroom has a modern projector which
enables me show pictures nicely .In addition, the area of the classroom is enough to do the
lesson So , I will need in the Classroom twelve Chairs, Two Whiteboards, projector,
computers
1.2.3 College :
I will present my lesson on Wednesday 19 of NOV at 09:50 Am at the RCT College is one
of the best technical colleges in KSA, and there are six technical majors is one of the
most important majors in our practical life. The duration of the study where six terms
to get Diploma Certificate. The number of students is also where about 1,200
students and 80 teachers. And there are many classrooms and workshops for each
department to compare the theoretical and practical. And also where the curriculum is
clear and contains of the theoretical part and practical part

2. Didactical Reflection
2.1 Introduction:
The Logic circuits are classified into two parts the first one called the Combinational Logic
Circuits in this part the output in any moment depends on the same time of the input , also in
this part the main construction by a logic gates . The second one called Sequential Logic
Circuits this type is distinction be existence a memory , so the output in any moment
depends on the last input for the circuits , in the Sequential Logic Circuits the main
construction by Flip Flop Circuits . The Flip-Flop is a logical and digital circuit that has two
stable states and can be used to store state information , The circuit can be made to change
state by signals applied to one or more control inputs and will have one or two outputs. Finally
you can connect the Flip Flop to make a logic circuits for example Counters and Shift
Registers .Flip Flops and Latches are a fundamental building block of digital electronics
systems used in computers, communications, and many other types of systems .
2.2. Curriculum Analysis :
This course talks about Logic Circuits [167 ELC]. The contact hours for this course are 72
hours. The hours of lecture are 36 hours. The hours of workshop are 36 hours. The hours of
tutorial are 0 hours. This course will make the trainees will gain practical and theoretical skills
on how to deal with: Number systems , Coding , Logic gates , decoder, timers, registers
,comparators , Combinational and Sequential logic circuits. This course aim of this course is to
promote understanding of different logic gate operations, combinational logic circuits, simple
sequential circuits and number systems to enable trainees to deal with different complicated
digital systems. The Behavioral goals is Understand how to differ between the binary and
hexadecimal numbering systems and how to convert from system to another, Operate and
testing the logic gates, Recognize types of flip-fops and determine the difference between each
one.

2.3. Content Analysis :
The topic is about the T type of Flip Flop, so that provide how you can make the time
diagram for JK & T Flip Flop . Also how you can build the truth table . Finally , The trainees
must know the types of Flip Flop and what is the function of Flip Flop and where we use it .
The Flip-Flop is a logical and digital circuit that has two stable states and can be used to store
state information.
2.3.1. JK Flip Flop :
The JK Flip Flop augments the behavior of the SR Flip Flop (J=Set, K=Reset) by interpreting
the S = R = 1 condition as a "Flip" or Toggle command. Specifically, the combination J = 1, K
= 0 is a command to set the Flip Flop , The combination J = 0, K = 1 is a command to reset the
Flip Flop , and the combination J = K = 1 is a command to Toggle the Flip Flop .
This is the Equation Circuits for JK Flip Flop it is about four NAND gates 2 of them have
three input the inputs for every gate is different , so in the first gate we see the J is input and
the second input is CK also the third one is coma from the Q negative . In the second NAND
gate the K is the first input and the second input is CK also the third one is coma from the Q .
We still have two gates so the input for the third one is connected with the output of the first
gate and the second input come from the output for the fourth gate and the output called Q
negative . The last gate is connected with the output for the second gate and the second input
came from the output for the third gate and the output called Q .

Time Diagram :
Truth Table :
We can get the time diagram from the truth table .
2.3.2. T-Flip Flop :
A T Flip-Flop can be built using a JK Flip-Flop (J & K pins are connected together and act as
T) If the T input is high, the T Flip-Flop changes state ("toggles") whenever the clock input is
strobed . If the T input is low, the Flip-Flop holds the previous value.
The mean goal of using the T type of Flip-Flop to get only on state its Toggle, so the name
of this Flip Flop are coming from Toggle .

2.4 Didactic Analysis :
In my lesson I use the Horizontal Didactic (from Abstract to simple ) by ask my student about
something is obscure so my student try to solve it and define it . After that I start explain my
lesson I will ask the trainees about the Flip Flop why I ask because my subject depends on it .
Also the trainees must have a knowledge about how the Flip Flop work to get the right
idea about it . After that I will give them a general information about the Flip Flop the
trainees will understand that clearly . Next I will talk about the JK and T-Type Flip Flop it is
a JK Flip Flop connected together and we will complete the truth table . also draw the
time diagram , finally I will talk about Master Slave Flip Flop so I must to give them the truth
table , the simple , and draw the time diagram .
2.4.1. Methods :
I’ll use a different methods for example :
 Classroom-Conversation this methods help the trainer to make the Trainees reactive
also to motivate them , this methods also help Trainee to breaking down barriers
between them and Trainer.
 Lecture the lecture is useful to gain the information and share experience whit the
Trainees . This allowed the Trainer to controlling the class and
 Partner Work this methods is the best because it make all Trainees are active and it
broking the shy. This methods it is useful for the Trainee because they are converse
together and help us to understand the lesson .
2.4.2. Media :
I will use it the Whiteboard to make some point easy to understand and Projector it is a new
valuable classroom management tool , also Projectors enable teachers to create bulleted
PowerPoint Presentations or other highly organized notes for the class. With the use of
projectors in the classroom, students can take better notes with the ability to discern what
information the teacher displays is most useful to them. Additionally, students can ask the
teacher to repeat a slide if they missed information, or even ask that the teacher to email the
presentation for further review. Also I will use Work Sheet
