Teaching Pattern

Methodology Laboratory manuals will be provided to students and the manual will contain descriptions on the basics and background of the experiment. Stepwise instructions will guide the student through the experiment. Teaching staff will demonstrate the operation of more complicated instruments. Students will be questioned on the meaning of certain procedural steps in carrying out the experiments. Students have to hand in written reports and give answers to specific questions raised in the laboratory manual. Report writing is intended to develop the students’ ability in technical and scientific writing.
