For rebuilding a teaching unit by making use the systemic approach we should follow a unified methodology of numerous steps that can be summarized in the following:
- First: The general systemic aims and the operational objectives for the unit should be defined.
- Third: The content analysis of the unite into facts, concepts, laws, relations, skills and affective issues should be carried out.
- Fourth: Draw a diagram illustrating linear relations among the concepts mentioned above.
- Second: The Prerequisites needed for teaching the unit from previous studies (facts, concepts and skills) should be tabulated into a list.

Where X, Y, Z, E, F, G, H represent
the concepts contained in the teaching
unit with its relevant facts and skills etc.
Notice that all the above relationships
are linear and separated from each
other.
- Fifth: We put the sign () on the already
known relationships from previous studies,
assuming the linear relations (X-E), (X-Z),
(X-Y), then the remaining linear relations
(X-F), (X-G) and (X-H) are unknown. So,
the diagram will be modified as shown in

the unknown ones.
Notice from the above diagram that
linear relations from (1-3) are known
and notified by the sign (), and the
heads of arrows are defined (), while
the relations (4-6) are undefined and
notified by the sign (?) and the heads of
arrows are not defined ().
- Sixth: The above diagram is modified to a
systemic diagram by adding relations
between the concepts (H-Y), (Y-Z), (Z-E),
(E-F), (F-G), (G-H) which are the relations
from 7-12 as shown from the following
systemic diagram (SD0).

(SD0)
From the systemic diagram (SD0) notice the following: a) The relations (1-3) are known, so the
heads of arrows are defined () and take the sign ().
b) The known relation between two concepts may be reversible i.e. in both directions and indicated by reversible arrows , but for simplicity we will consider the relations between concepts have one direction ().
( )
c) The relations from (4-12) are not
defined yet and will be determined
during the study of the unit and so
take the sign (?) and the double
headed arrows ().
d) The systemic diagram (SD0) can be
called as the starting systemic of
teaching the unit.
- Seventh: We define a scenario for
teaching the unit where the relations
(7,8,9) in the primary stage of the unit
teaching are defined, and then added
to the SD0 diagram to obtain SD1
diagram.

From the above SD1 diagram the following points can be noticed:
a) The relations (7,8,9) became defined
and the arrows directions determined
() but the remaining relations
(4,5,6,10,11,12) are still unknown and
will be defined later during the study
of the remaining parts of the unit.
b) The student in the first stage of the unit study has identified the relations (7,8,9) and connecting them with the formerly studied relations (1,2,3) and those he will study in the remaining parts, of the unit.
c) In this stage of the unit study we can ask the students to build systemics showing the relations between the concepts (X, Y, Z, E) during the systemic assessment [Cf. the systemic Assessment (1)]
- Eighth: In the next stage of the unit
study, the student can study the
relations (4,5,10,11) and then he will
be able to add them to SD1 to obtain
SD2.

From the above diagram, we notice the following:
a) All the relations became known except the two relations (6,12) that will be identified in the later stage of the unit study.
b) At this stage of the unit study, the student could study the relations (4,5,10,11) in view of the Previous studied relations and those that will be studied (6, 12).
c) The student can build several systemics showing the relations he studied during the systemic assessment [Cf. the systemic assessment (2)].
- Ninth: In the last stage of the unit study, the student studies the two relations (6,12) in view of the previous studied relations, then he adds them to SD2 to obtain SD3 where the systemic teaching and learning the unit becomes completed.

From the systemic (SD3) diagram, the
following points can be observed:
a) All the relations between concepts (1-
12) became known.
b) The SD3 can be then called as the
terminal systemic of teaching the unit.
- Tenth: From the scenario of teaching
the unite we can observe the following:
a) We started the unit teaching by the
systemic diagram (SD0), that has
determined the starting point of the
unit and we ended with the systemic
diagram (SD3) that defined the
terminal point of the unit and
between both diagrams we cross over
the diagrams (SD1) and (SD2).
b) We started the unit teaching and continued by the systemics from (SD0) to (SD3) and all are similar except a number of known relations () and the unknown ones (?). As we proceed in the unit teaching, the unknown relations become dimini-shed while the known ones increase until we reach the unit end where all the relations became known as indicated in Fig (3).

Therefore the systemics can be used as
a method for teaching and learning but
not as summaries for memorization. It
helps the teacher to teach and the student
to learn and can be utilized from the
beginning of teaching the unit till its end.
- Eleventh: The students are aware a bent the pathway of teaching the unit from its beginning to its end. This can raise their learning motivation and helps them to interconnect the knowledge they study at any of the teaching stages with the past and the next concepts in the unit, that could help students to build a correct cognitive structure.
- Twelfth: At the end of the unit study,
student could be asked to build
numerous systemics that show relations
between 3,4,5 or 6 concepts etc. This
can indicate the extent of student
achievement of the unit teaching
objectives through the final systemic
assessment [Cf. Assessment (3)].
Systemic Assessment(SA)
Systemic Assessment(SA)
It is already known that the
curriculum systemic is composed of
objectives, content, teaching methods,
media and assessment.
In order to have a systemic curriculum
the following should be done:
1- The objectives should form a systemic.
2- The content should be arranged by a
systemic method as shown in SD0.
3- The teaching method should be systemic that starts by starting systemic (SD0) and ends by terminal systemic (SD3), passing by intermediate systemics (SD1 and SD2), (Fig. 3).
4- The multimedia should be systemic, helping for teaching the unit systemically.
5- All the above curriculum components
should interact and be in harmony,
affecting one another into one
systemic unit, then the assessment
comes stepwise from the beginning of
the unit teaching till its end.

Advantage of (SA):Advantage of (SA):
The systemic assessment (SA) has the
following advantages:
1- It measures the cognitive structure
from the cumulative (quantitative) to
the interactive and tuned
(qualitative).
3- It helps the student to compose his
knowledge into a solid cognitive
structure from the beginning of the
course to its end.
2- It measures the higher levels of
learning (Analysis, Synthesis and
Evaluation).
4- It helps the student to corporate the
concepts he learns at any educational
level with what he has been taught in
the past, helping his cognitive
development.
5- Being comprehensive, covering all unit parts.
6- Being objective, realistic and valid.
Types of Systemic Assessment: Types of Systemic Assessment:
Systemic Assessment (SA)has various types as:
1- Multiple choice questions (MCQs), in which one correct systemic diagram to be selected from among others.
2- Constructing Systemic diagrams from their components.
3- Analysis of a systemic diagram into
subsystemics.
4- Completion of systemic diagrams with
the missing elements.
Geometric Forms of Systemic Questions (SQs):
Geometric Forms of Systemic Questions (SQs):
In the systemic assessment questions
take different geometric forms as
triangular, quadrilateral, pentagonal,
Hexagonal, ….etc.
We must take into consideration the
following points when we put these types
of questions.
1- Concepts or facts are placed at the corners of these diagrams.
Represents concept or fact.
2- We must use the sides of these
diagrams as arrows point to the
relationships between concepts or
facts.
Represents relation
3- The head of arrows could directed clockwise or anticlockwise.
(Clockwise) (Anticlockwise)
(Clockwise) (Anticlockwise)
4- The relation may be reflected on all or some sides of the diagrams.
“Reflected on all sides”
“Reflected on one side”“Reflected on two side”
Assessment (1, and 2) came after
teaching some parts of the unite, so they
are formative, However, assessment (3)
comes at the end of teaching the unite so
it is summative.
