SYSTEMIC ASSESSMENT AS A VEHICLE TO ASSESS STUDENT ACHEIVEMENTS IN CHEMISTRY By Prof. FAHMY A. F. M. E-mail: afmfahmy 42@gmail. com ; web site: www. satlcentral. com 1 st ACRICE –W-1 Dec. 2013

INTRODUCTION -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.

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. Help teachers to use evidence of student learning to assess student achievement against goals and standards of the courses and programs. .
