4 Lab Instructions Several practicals / programs? Whether an experiment contains one or several practicals /programs One practical / program Lab Teacher forms groups of the students based on All Students need to perform the practical/program Assign all practicals /programs among all groups Teacher decides whether the completed practicals / programs can be appropriately described using flow chart, algorithm, query statement, etc. Teacher issues necessary instructions to the students for writing practicals / programs accordingly Students write experiments in practical files and get them signed by the lab teacher Students make entries in the list of contents of the practical files and get them signed by the lab teacher Whether practical has been verified and signed by the lab teacher?? If a student has not completed a practical, he/she is expected to complete it at his/her own with the help of his/her fellow students in his/her hostel The student completes the practical file and submits it to the concerned teacher in his/her office or mail box on next working day In case of an experiment containing several practicals, a lab teacher needs to think whether a practical performed by the students in one group needs to be repeated by the other groups in lab on the same day? OR A practical performed by the students in one group needs to be repeated as assignments to be completed by the students of other groups in their hostels? Here, an assignment includes both executing a program on computer and also writing the same in practical file. OR A practical performed by the students in one group needs to be repeated as assignments, only writing practicals in their practical files, for the students of other groups in their hostels? Teacher issues necessary instructions to the students accordingly.
