The COVID-19 pandemic forced a quick change of the teaching styles to online lessons; specifically, experimental classes had to be redesigned to achieve the best possible academic performance within the imposed limitations. This work describes three different approaches: adaptation of a laboratory chemistry course to an online mode, learning proficiency, and students’ perception. First, a compilation of experiments that cover topics from general chemistry at an undergraduate level was included, with activities that can be conducted employing daily-use materials and substances. Next, the learning achieved was estimated, and the grades were related to a domain level of competency acquisition. The results indicated that at least 68% accomplished the highest level. Finally, the perception of the participants about the activities was inquired. The statistical analysis showed a generalized positive attitude towards the mode proposed, an appreciation of having earned meaningful knowledge, and most of the students stated they would recommend the course.
This review examines the impact of the COVID-19 pandemic on higher education in Mexico. It acknowledges the difficulties and disruptions caused by the global emergency but also emphasizes the opportunities for reflection and learning that have emerged. This work employed a comprehensive methodology, including a thorough literature search across multiple academic databases and consultation with national statistical sources and newspapers. Sixty-nine articles were selected based on predetermined keywords and criteria, leading to the identification of two central themes: impacts and implications on higher education and innovation in teaching and learning experiences. The findings shed light on the effects of the pandemic and highlight the need for resources, pedagogical considerations, and a reevaluation of priorities in the education sector. The review concludes by emphasizing the importance of improving equity, quality, and long-term sustainability in higher education in Mexico while recognizing the opportunity for educational reform in the post-pandemic era.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
