The gradual shift to online modes of learning in higher education institutions over the past 2 decades accelerated drastically on a global scale between 2020 and 2022. Students and educators, who have initially grappled with the shift, have now become accustomed to online teaching; however, there are concerns about the quality of learning that has resulted. To enable a sustainable and effective online pedagogy, educators may need to learn about fostering higher-order thinking skills, which can be challenging even for experienced educators. To conceptualise effective online pedagogy, the community of inquiry (CoI) framework emphasises cognitive presence (CP), which focuses on the higher-order thinking process. The CoI is the most widely researched framework in online pedagogy, yet contemporary CoI literature lacks collective evidence of factors that influence CP. This scoping review of the CoI literature explores the factors that influence the higher-order thinking that is indicative of CP. Inclusion criteria included evidence of CP in online learning contexts and published between January 2000 and March 2022, providing a total of 121 studies. Results suggest that teaching presence, structure of learning activities and student characteristics all influence CP.

Hemolytic disease of the newborn (HDN) is a potentially fatal condition caused by a Rhesus (Rh) antigen incompatibility between a mother and fetus. As a result, determining the Rh status of expectant parents is a routine clinical assessment. Both the physiological and immunological basis of this condition are taught to undergraduate students. At the University of South Australia, some undergraduate immunology students find this topic challenging. The author designed, implemented, and assessed the impact of an interactive simulation to facilitate student learning of HDN. The students were actively engaged in determining the blood grouping and Rh status of an expectant mother and father and then determining the possibility of developing HDN. The simulation was found to take only 15 min to complete yet led to a significant increase in student performance in an end of semester exam question. Student perceived understanding was found to significantly improve following the introduction of the simulation, even though the content had been covered in a formal lecture. Student feedback was highly positive of this learning approach. In conclusion, short, interactive simulations can be used effectively to enhance student learning of challenging concepts.

A hemocytometer is a key piece of laboratory equipment typically used in diagnostic and immunology research laboratories to enumerate white blood cells. The accurate quantification of cell density is essential to ensure accurate numbers of cells are added to assays to generate valid data. Hence, learning to correctly use a hemocytometer is a critical skill for all undergraduate immunology students. However, this skill can be challenging to learn because of students’ unfamiliarity with correct cell identification, differentiating viable versus dead cells and mathematical proficiency in calculating cell density and viability. To address these issues, we developed an interactive computer simulation that replicated all aspects of a Neubauer‐style hemocytometer. This simulation was used to teach second‐year undergraduate immunology students before a face‐to‐face (F‐2‐F) laboratory exercise where these skills were applied. Using a mixed methods approach, student performance and feedback were collected on broad aspects of the intervention and its benefits to the F‐2‐F setting. The approach was found to be extremely successful with all measures indicating a significant impact of the virtual hemocytometer on student learning, understanding and confidence. We suggest that integrating an online simulation to teach students the fundamentals of hemocytometer use and calculations is a valuable educational aid for learning this important skill.

The method for producing monoclonal antibodies (MAbs) was first published in 1975. MAbs have revolutionised research, diagnosis, and disease treatment approaches. While students need a good understanding of MAb production, teaching the key steps via traditional methods can be challenging. Numerous resources exist, but these focus on hybridoma selection omitting other key steps. In 2016, an interactive simulation was developed where students produced a virtual MAb. The simulation was used in conjunction with a lecture and tutorial, providing an alternate approach for students to learn and test their understanding. The simulation is interactive, placing students in charge of all key decisions, with immediate feedback provided at all stages. The impact of the simulation on student learning was assessed between 2017–19. Ten formative multiple-choice questions were included so students could test their understanding. The impact of the simulation on student performance was assessed in a quiz. Students that used the simulation consistently scored significantly higher in all assessment items than students who did not access the simulation. Students were engaged and the positive feedback indicated that they enjoyed this novel, alternative teaching method. This demonstrates that a simulation is a novel, learning aid for teaching students all aspects of MAb production. [ABSTRACT FROM AUTHOR]

At the University of South Australia (UniSA), Biochemistry is a second year undergraduate course. The student cohort is diverse, with students enrolled in courses with a laboratory focus, such as Laboratory Medicine, Medical Science, Nutrition and Food Science and Pharmaceutical Science. The course is taught in a traditional manner, with weekly lectures, fortnightly tutorials and three practical sessions. In response to the growing numbers of COVID-19 cases, in mid-March the University leadership moved to cease face-to-face teaching. By this time, 58 of 96 students had completed the first two (of three) face-to-face laboratory practicals. In response to this decision, teaching of all practical based content was moved online for all students. The first question was, how do we teach practical content online? And secondly, how do we teach hands-on skills? The first question was addressed using a suite of online simulations, progressively developed since 2013. Simulations are widely used and shown to be useful as teaching aids in STEM. A total of five simulations were introduced each covering key aspects of laboratory practice, including fundamental mathematical skills, reading, and setting a pipette, basic Biochemistry assays, protein quantification, and enzyme kinetics. The second issue of teaching hands on skills was addressed once restrictions were eased. Students were invited to attend the laboratory to learn the kinesthetic skills with instructor guidance. Both approaches used proved to be highly effective and can be readily adapted not only to teaching Biochemistry, but any aspect of science education.

This article covers the career pathway of a research-trained scientist to an immunology educator in a university setting. However, a solid foundation in science greatly contributes to student learning and is recognized by universities as an academic pathway to career growth. 5 Costabile M, Nguyen H, Kenyon A.
