Introduction: Critical thinking is a vital component of postsecondary education. Active learning and experiential learning strategies in the classroom are effective ways to help students develop critical thinking skills. This paper focuses on two faculty development workshops, the purpose of which was to improve critical thinking skills through guided active and experiential learning opportunities. Over the past few years, we developed and facilitated these workshops on various postsecondary campuses, which have produced improvements in the attendees’ classroom assessments and students’ critical thinking skills. These faculty development workshops around critical thinking were designed to equip educators with pedagogical strategies that have been researched to work in relevant postsecondary classroom settings. During these workshops faculty members share their experiences with each other and work together to develop discipline-specific solutions that enhance teaching and learning. As a result, there is an opportunity to increase faculty engagement and interactions, which may lead to the development of a community of educators. 

Polyaniline is a conducting polymer in which both redox and protonating/ deprotonating conduction mechanisms are activated in the presence of gaseous compounds, making it a gas sensor. Resistive chemosensors based on PANI, in particular, have been well studied for their gas sensing properties and are considered important sensing materials for a wide range of applications as they operate at room temperature. There is, however, a novel class of polyaniline hybrids with cellulose acetate that may be suitable for detecting biomarkers emitted from the skin and in measuring the pH of breath condensate for diseases and thus, worth studying them further.
