In a technology-centric world, leveraging digital tools such as chatbots allows educators to engage students in ways that may be more accessible for both parties, particularly in large lecture classrooms. This report details the development of an interactive web-based chatbot to curate content for writing about chemistry in context. Students were assigned a 500-word paper where they discuss general chemistry concepts through the lens of a timely, sustainability-related topic, i.e., water footprint, carbon footprint, or embodied carbon. Discussed herein are the development of the decision tree, the chatbot’s components, and results from the initial implementation in a large lecture general chemistry classroom. Over 78% of the 347 enrolled students (271) used the chatbot over 350 times in the 3 weeks leading up to the assigned due date of the paper. Eighty-three percent of the interactions were captured for further analysis, which showed that 22% of students used the chatbot more than once. Forty-six percent of recorded interactions were used to aid students in developing or refining their idea for the assignment. The curated chatbot technology reported here for writing assignments in chemistry can be readily adapted to other aspects of coursework in chemistry. 

Scientific instruments have long been a vital part of science, paving pathways to remarkable scientific advancements. Such advancements have changed the world both socially and culturally, especially in the past few decades. Students can be introduced to this idea through the concepts of nature of science (NOS): scientific observations are often filtered through apparatus, inferences can be made through observations, and science is a socially and culturally embedded practice. The curriculum often fails to emphasize the role of instruments in scientific practices, even in teaching laboratories. This study uses semistructured interviews to investigate the cognitive (thoughts) and affective (feelings) domains of first-year university students as they relate to scientific instrumentation, including students’ ideas of instruments. First, the study probed how general chemistry students conceptualize scientific instruments in relation to the three NOS notions. Second, students’ practices related to experimental data evaluation were investigated as data collection is a large part of psychomotor learning in laboratory. Third, students’ affective states toward learning about instruments were queried. The interview results suggested that a majority of participants acknowledge some ideas of NOS, while a few students displayed an advanced understanding when discussing scientific instruments and also tended to have higher interest and motivation toward learning about instruments.
