SYSTEMIC ASSESSMENT AS A VEHICLE TO ASSESS STUDENT
ACHEIVEMENTS IN CHEMISTRY
-Systemic Assessment [SA] has been shown to be highly effective new vehicle in;-Raising the level of students academic achievements.-Increasing equity of students learning outcomes. -Improving students’ ability to learn by enhancing the process of teaching and learning. -Involving the student as an active candidate in this process.
INTRODUCTION
Why Systemic Assessment (SA) ?
]1[ It measures the cognitive structure from the cumulative (quantitative) to the interactive
and tuned (qualitative). ]2[ Assess students higher-order thinking skills in
which students are required to analyze , synthesize, and evaluate .
[3] Measures the students’ ability to correlate between concepts.
[4] Enables the students to discover new relation between concepts.
]5[ Assess the students in a wide range of Concepts in the course unites .
]6 [ Measures the systemic ILO,s, beside separate Linear ILO,s.
[7 ] Develop the ability to think systemically , critically and creatively, and Solve problems.
]8 [ Being objective, realistic and valid.
[9 ] Very easily scored.
Goal of Systemic Assessment:
-The main Goal of SA is to enhance, support and improve both teaching and learning processes via:
[1] Enable students to make feedback and feed forward during their study of any course materials.
[2]Help students in making maximum connections between Chemistry concepts, compounds,
and reactions.[3 ]Enable students to achieve the highest standards
they able.]4 [Help teachers to use evidence of student learning
to assess student achievement against goals and standards of the courses and programs.

Types Systemic Assessment Questions: [SAQ,s]
1- Systemic Multiple Choice Questions [SMCQ,s].
2-Systemic True, False Questions [STFQ,s] .
3-Systemic Matching Questions [SMQ,s].
4-Systemic Sequencing Questions [SSQ,s].
5-Systemic Synthesis Questions [SSynQ,s].
6- Systemic Analysis Questions [SAnQ,s].
Type-1: Systemic Multiple Choice Questions (SMCQs)
MCQs are the traditional choose one from a list of
possible answers. However (SMCQs) are choose
of one systemic from a list of possible systemics.
Each systemic represents at least three chemical
relations.
Form (I): Choose From Triangular Systemics:
