Intentional reflection is a key component of Community Service Learning (CSL) as it guides students to integrate knowledge of theory with experience in practice. A semester-long chemistry curriculum with an integrated CSL intervention was implemented in a Canadian university to investigate how reflection in the laboratory setting enhances post-secondary students' (n = 14) conscious awareness of their learning and their attitudes toward having reflection as part of a course. In typical chemistry laboratories, students follow cookbook recipes from the lab manual and are assessed through written lab reports. These lab reports are similar to a technical report with scientific writing where the design aims to communicate scientific information to other scientists. A case study was conducted with reflective essays, focus group interviews, and student observation to analyze qualitatively how students' attitudes changed in their learning over the course of the CSL activity and how they engaged in this type of reflection. The expected audience that may be interested in this study are those involved in teaching chemistry in higher education and those that are interested in Community Service Learning and experiential learning. The results demonstrate that science students are able to articulate their academic growth, civic engagement, and personal growth through reflective pieces. Furthermore, the reflective pieces support self-regulated learning with a positive engagement and attitude over time. The results support the integration of reflective pieces in laboratory settings.
