A Chemical Analysis Laboratory Class Solely Assessed on the Accuracy and Precision of Student Data
Bhavik Anil Patel
Journal of Chemical Education, v99 n10 p3585-3589 2022
Accuracy and precision are measures of experimental error and are fundamental to most chemical analysis laboratory classes. Assessment of accuracy and precision is often based on the comprehension of the results generated by students rather than on the quality of the data generated. This activity focused on developing a chemical analysis laboratory class which focused solely on assessing the accuracy and precision of the data generated by students through a series of assays they conducted by following the British Pharmacopoeia monograph for paracetamol tablets. Students were given two attempts to conduct each assay. Guidance and feedback on the students' experimental practice was provided after the first attempt, to educate students on how they could improve the accuracy and precision of the data generated. For all assays conducted, the accuracy and precision was improved in the second attempt. Students felt the pressure of being assessed solely on accuracy and precision but found that this laboratory class enhanced their confidence in generating accurate data. Overall, students felt that this class provided a reflective experience of working within the chemical industry and thus provided a key activity to enhance student employability.
