What is the most appropriate technique for evaluating students in a laboratory-based course?

In a laboratory-based course, the most appropriate technique for evaluating students is the use of product or performance checklists based on established standards. This method aligns closely with the hands-on nature of laboratory work, where practical skills, techniques, and specific outcomes are essential for understanding and applying the material.

Using performance checklists provides a structured and objective way to assess students' competencies in executing laboratory procedures, adhering to safety protocols, and achieving desired results. This technique allows instructors to observe specific tasks, supporting consistent evaluations across different students and ensuring that all relevant skills are assessed thoroughly.

In contrast, while written exams may test theoretical knowledge, they do not adequately evaluate students' practical abilities or their proficiency in performing laboratory tasks. Peer assessments can offer valuable insights into teamwork and collaboration, but they may not focus on the individual skills necessary for success in the lab setting. Oral presentations, though beneficial for assessing communication skills, do not directly evaluate hands-on execution of laboratory techniques. Therefore, the use of performance checklists is the most fitting approach in this context.
