We analyze our data both quantitatively (using the Danczak-Overton-Thompson (DOT) test) and qualitatively (using student feedback). The course components designed to teach for critical thinking are an open-ended group exercise called “The Chocolate Conundrum”, self-reflection exercises for students to self-assess their critical thinking skills, and a group project designed to enable students to learn to critically review a peer-reviewed journal paper. By linking these components to established teaching theories and synthesizing current knowledge in the field into practical exercises that can be added to current science undergraduate courses, our work highlights how simple and innovative approaches for fostering critical thinking can have impactful outcomes.

Within the subthemes of General Laboratory Skills, Purification and Characterization Skills, and Professional Desk-Based Skills, ten key microskills that align with course objectives were identified. A visually attractive badge icon that clearly illustrates the specific achievement was created for each. Development of each skill was presented as a standalone short-term goal to be rewarded with an individual task-completion badge. Award criteria included effort and engagement with structured prelab activities, including LearnSci lab sims, instructional videos and online quizzes, hands-on laboratory experience, and postlab reporting. The broad range afforded students opportunities to construct their knowledge and skills across different scenarios, both on and off campus. Award criteria were judiciously selected for their compatibility with our Virtual Learning Environment, Moodle, and its badges plugin. In this way, the logistical demands of validation and badge issuance for a large enrollment class were serviced by technology. Across two academic cycles, ∼3,250 badges were awarded to ∼370 students.

This laboratory experiment was designed to teach junior or senior-level undergraduate students two commonly used extraction techniques, supported liquid extraction (SLE) and solid phase extraction (SPE), for extracting methamphetamine (MA) from MA-spiked urine, with detection and quantitation via gas chromatography–mass spectrometry (GC-MS). Specifically, the performance of SLE was compared with that of the mixed mode nonpolar/cation exchange SPE, and the effect of different extraction conditions on the recovery efficiencies was discussed for both techniques. Furthermore, students were introduced to key quantitative concepts, such as accuracy, precision, controls, coefficient of determination (R<sup>2</sup>), and coefficient of variation (CV %), etc., all of which are critical for method validation and ensuring the reliability of analytical results.

Centralized training is a comprehensive training method that incorporates a well-structured knowledge system. This method is implemented at the commencement of the semester. Dispersed training exhibits a fragmented structure, with its content being determined by the course experiments and distributed across the semester. By segmenting the experiment process and categorizing unsafe behavior, we studied the incidence of students’ unsafe behaviors and risk profile for different training methods. The data show that the effects of centralized training in reducing unsafe behaviors seem to be limited. In contrast, dispersed training seems to be effective in reducing the incidence of most unsafe behaviors in the laboratory, thereby reducing safety risks. The statistics show a significant difference between centralized and dispersed training in reducing students’ unsafe behaviors.
