Assessment of Lab Work

The performance of the student in the course of his/her project work will be assessed relative to the learning objectives above, using the criteria and descriptors below. In each section, the supervisor will select the statement (descriptor) which most closely describes the consistent performance achieved by the student towards the end of the project work. In some cases, for example data interpretation, the worst or best manifestation of this criterion may be taken into account.

The descriptors below are ranked in order of increasing value. Each one carries a mark appropriate to that value and the average of these marks for the 14 sections, expressed as a percentage, will comprise the total mark for Approach and Technique, which itself forms 30% of the project mark. For certain types of project, it may be appropriate to omit one or two sections. In such cases, where the omissions are justified by the supervisor, the average of the remaining sections will be used as the basis for the mark.

Although importance of practical work has a long been recognized but unfortunately in the past laboratory work has un-assessed in its true spirit. Science as knowledge and information has been favoured at the expense of science as skills and processes. Christofi (1988) argues” if it is important enough to teach, then we must also assess it, if practical work is not tested, it will undoubtedly be valued less by science students. 

In this unit, two important uses of assessment i.e assessment for feedback and assessment for grading have been described in details. Various techniques of assessing the laboratory work have been discussed. Assessment of research projects is also described at the end of this unit.

 

OBJECTIVES

After reading this unit, you will be able to:

  1. understand how assessment is used to take feedback of the work done in laboratories?
  2. know why and how the assessment is helpful in grading the laboratory work of the students?
  3. familiarize and use techniques for assessment
  4. know and use the assessment techniques of research project.
