Teaching tools:
2

Lectures presented in Microsoft PPT, ChemDrawUltra drawings and presented to the students
using DataShow . The class Board also used for more clarity.
 The lecture indicates feedback of the last lecture, preliminary introduction, about 8 slides show
will be explained for 45mn. Question/ answers discussed, solving sample questions for 5mn.
 Copies of lecture/ notes usually giving to the students in MO.Word on USB flash memory stick,
hard copy/ handouts and at the end of each month a copy of notes to be placed on the college
website & library.
 Every sitting exam assigned for the students, question papers corrected, marks rewarded, a
following lecture will discus and solve the exam questions and place a copy of answers into their
notes after giving several ways of answering.
 The corrected question papers are shown to the students for reviewing their errors. Exam answer
papers are to be saved for future references.The exam paper covers most of the lectures given
and indicated: Exam instructions, selective answers, definitions, chemical equations, explain,
Draw, write an assay, calculations, differences…etc. The questions usually are clear, direct and
obvious ranged from difficult, moderate to easy.
 Every student activity will be recorded, saved and notes will be taken by the lecturer for all over
the academic year.
 All student marks & announcement will be displayed on the department notes board.

All year student efforts will be calculated and added to the summer exam out of a 100%.
Students who passed the first attempt summer exam will be granted next level of study.
Students who failed shall sit the autumn second attempt exam.
 Practical experiments should be taken by students.
