Systemic Education Reform [SER]
A Global View SATLC SA ST S.E.R. Each systemic component interact with the other two components of SER .SA was used to assess thr students achievements after exposed to SATLC. However, SA is used to enhance ST. Also, ST is one the important learning outcomes of SATLC.

About 20 years ago Fahmy & Lagowski set up SATLC to Face;
PART-I: SATLC INTRODUCTION About 20 years ago Fahmy & Lagowski set up SATLC to Face; The world challenges such as Terrorism, world Economic Cries, Environmental Pollution...etc., The wide spread of the systematization in activities such as Tourism, Commerce, Economy, Security, Education etc.., Globalization that we live and survive with its positive and negative impacts on our life . So, SATL became a must and Countries are in an Urgent Call to Prepare Their Ctizens to be able To Think Systemically and Creatively in the Golbal Age
5
SATL- has been applied in:
-Basic sciences (chemistry, biology, physics, mathematics), Applied sciences (Environmental sciences, Agricultural sciences, Pharmaceutical sciences, Engineering sciences), law, medicine, linguistics and commercial sciences ( But, however, most of the efforts on SATL methods have been expressed in chemistry . SATL is considered as a way of teaching and learning that intensify deep learning which differs from surface learning that focuses on rote memorization and superficial understanding of concepts.
6
Cardellini [2010] shows that;
It is possible to plan a New Systemic Way of Teaching Starting from the SATL, Pointing Out Either The Connections ‘Internal’ To the Discipline OR ‘External’ Ones Related To The Interactions with The Surrounding Environment In a Global Systemic Perspective. -. Also, Technical High School students Represent A Target Suitable for SATL Strategy Because they need to learn chemistry fundamental concepts in a shorter time without Losing the Connections Between Them & Their Role in Real Situation
7
Nazir et al [2011] stated that;
-Teachers Can Mnimize The Difficulties in Concept Building By Providing Better Perspective Related To The Basics of The Subject. -This can be Accomplished Through Novel Efforts Involving Personal Input -SATLC Teaching Method has been Discovered To Play An Essential Role, Towards The Efforts for Promoting Better Understanding of Chemical Concepts
8
Nazir et al [2011] stated that;
-Teachers Can Mnimize The Difficulties in Concept Building By Providing Better Perspective Related To The Basics of The Subject. -This can be Accomplished Through The Novel Efforts -The Recently Emerged Concept Based Teaching Methodology, (SATLC), is a Fascinating Route To Meet This Noble Endeavour. -In addition to that, the results reported from the Evaluation of SATL technique have been Very Promising Due To The Improvements in Sudents' Academic Achievements
9
-SATLC is an Important Changes in the way of
-Golmi et al [2013] stated that ; -SATLC is an Important Changes in the way of Organization of concepts which intend to increase; -The yield and quality of the teaching process -The role of teacher as organizer -The student as an active part in the process of learning.. -SATLC-Creates Some what Closed Cluster of Concepts, which Highlights Interrelations between Concepts. -.
10
Herin et al [2014] stated that; It is More Difficult To Obtain
A Global View Of a Collection of Concepts With Linear Representation OR Even with Cocept Map Than With A Systemic Cosed-Cluster Representation of Concepts Which Stresses all Relationships Among The Concepts
11
. John Bradley [2014] Stated That;
-An Emphasis of SATL is the Interrelatedness of Things, Especially the Cross-Links between Vertical Developments of Concepts as are Most often Presented in Concept Maps. -The Three Levels of Science Thought (Macro, Micro, Symbolic), identified by Johnstone and represented by a Triangle, may be Viewed as a Core Closed-Cluster Concept Map of the Type Advocated in the SATLC.
12
Our educational systems suffer
Shortcomings of The Current Educational Systems: Our educational systems suffer From the Following Shortcomings: 1-Low Performance of the current Curriculum System: -Due to the linearity of each component of the curriculum system. - In order to get a maximum performance of the systemic curriculum, it is necessary that each of its components should be build systemically and acts as a sub-systemic (Fig.1)

15
Why SATL IN CHEMICAL EDUCATION REFORM ?
-To Help Students To Understand Interrelationships between concepts in a greater context. -To Face The Current Global Challenges in the world such as global terrorism, global warming, etc. That requires preparation of Citizen to be able to systemic and creative thinking that solve such phenomena for a better world for all. -To change our Educational Systems from Surface To Deep Learning that prepare our graduates to meet the needs of the global markets beside high skills that enable them to live and act positively in the global age.
16
What is The Meaning of SATL ?
By"systemic“ We mean an Arrangement of Concepts or Issues Through Interacting Systems in Which All Relationships Between Concepts and Issues are made, Clear up front, To the Teachers and Learners (Fig. 3b), - In contrast to The Usual Linear Method of Teaching The Same Topics (Fig. 3a)

Systemic Teaching Strategy
We started teaching of any course by building Systemic diagram (SD0) that has determined the starting point of the course. We ended the course with a final systemic diagram (SDf) and between both we crossover several Systemics (SD1, SD2,..) Fig.4 SD0 SDf SD2 SD1 Stage (1) Stage (2) Stage (3) (maximum Unknown chemical relation between concepts) (All chemical relations between concepts are known) (?) () Educational standards and objectives Figure 4: Systemic Teaching Strategy

SATL Experiments in Egypt
We have conducted numerous experiments in EGYPT which we attempted to Establish The Effectiveness of SATL Methods not only in chemistry, but also in other basic sciences, Medicinal sciences, Engineering sciences ,Agriculture, Pharmaceutical, sciences, …… - In Chemistry, We have Conducted a Series of Successful SATL-Oriented Experiments, at Pre-university, and University Levels of Education. -We have created SATL units in General, Analytical, Aliphatic, Aromatic, Green, and heterocyclic chemistry. -These units have been used in Egyptian universities and secondary schools To Establish the Validity of The SATL on an Experimental Basis.
20
I-PRE-UNIVERSITY EXPERIMENT
SATL- APPLICATIONS I-PRE-UNIVERSITY EXPERIMENT SATL CARBOXYLIC ACIDS AND THEIR DERIVATIVES: -Our initial experiment on SATLC was conducted at the pre-college level in the Cairo and Giza school districts. -Nine SATL-based lessons in organic chemistry Fig.(5) taught over a two-week period were presented to a total of 270 students in the Cairo and Giza school districts; -The achievement of these students was then compared with that of 159 students taught the same material using standard (linear) methods Fig.6,.

Fig.6: Linearly based teaching and Learning
22
The results of experimentation indicate
-A greater fraction of students exposed to the systemic techniques, the experimental group, achieved at a higher level than did the control group taught by conventional linear techniques. - Students who had been taught by instructors using SATL Technique were more successful in the final examination in comparison to the students who had been taught linearly? - Success was defined as achievement of at least 50% in the final examination. Approximately 80% of the experimental group was successful,but only 15% of the control group reached the level of success.

2-SATL-CHEMICAL EQULIBRIUM
We can teach chemical equilibrium in the frame of systems at equilibrium (physical systems in nature, and biochemical systems in our bodies). Students with Teachers write the concepts of this unite (equilibrium, chemical equilibrium, factors affecting rate of reaction, conc., pressure, hydrolysis, pH, ….) Then Students with the help of teachers build the following systemic diagram (SD0).

3-GREEN CHEMISTRY : SATL VISION
Applying Systemics to laboratory instruction reveals the following advantages, which constitute the principles of benign analysis related to green chemistry aspects. * Smaller amounts of Chemicals are used. * Recycling of Chemicals. * Experiments are done with less hazards, and more safety. * Experiments are done more rapidly. * Students easily acquire a working sense of the principles of green chemistry.
42
analysis involves the application of linearly obtained
- Classical laboratory-oriented subject of qualitative analysis involves the application of linearly obtained chemical information to an unknown solution in a linear way In contrast to the linear approach of learning chemistry of cations from a laboratory experience, a systemic approach has been developed that focuses attention on individual species ((Fig.1) Exp. 4 Exp. 3 Exp. 2 Exp. 1 (?) A+X- A+E- A+Y- A+Z- Figure 1: Systemic Green Investigation of species A+(SI-Plane)
43
The diagram shows the Plane for qualitative investigation of the species (A+), the preparation of (A+) Compounds, and the interconversion of the species Applying this approach to laboratory instruction allows students to experience the colors of chemical species, their solubility characteristics, and their redox behavior. we have created. Qualitative Systemic benign analytical chemistry course for the first-year students of faculty of Sci., Benha, Zigzag University, and Faculty of Education, Helwan University, Egypt.
