Evaluation and intervention of students’ laboratory performance in chemistry graduating classes; Wachemo University, Ethiopia


  • Hadush Gebrehiwot Department of Chemistry, Wachemo University, Hossana




Active learning, Laboratory intervention, Pre-laboratory, Post-laboratory


Background: The laboratory courses offer students the opportunity to gain manipulative skills, observational skills, and the ability to plan experiments and to interpret experimental data. The laboratory can be an excellent environment for active learning. It has long been considered useful to develop conceptual understanding, but some recent courses have been developed that rely heavily on laboratory experience, in contrast to conventional teaching methods, for the development of conceptual understanding of sciences. The primary purpose of this study was to assess laboratory perceptive of the graduating class students’ of the department of chemistry and to engage them as active learners.

Methods: A total sample containing 20 students consisting of 14 males and 6 females were selected for the study. Four experiments were given to randomly selected participants in the respective strata and students were evaluated on the basis of different parameters.  

Results: The findings of this research showed that almost all the sample students fail to correlate their theoretical accumulation with the practical performance.

Conclusions: So, severe works should be made on the various issues concerning the laboratory to be a unique learning environment to create well skilled students.
