Student-generated videos: a model for developing written standard operating p...
Standard Operating Procedures (SOP’s) have an important role to play in laboratory operations, not only to maintain data consistency but also to ensure safe practice. Even so, development and use of them may be hindered by the perceived expense of time and effort relative to their expected benefit. While that cost can be minimized via the use of templates, this approach may produce documents that are not essential to practice if sufficient consideration is not given to the user’s experience. If, for example, the content does not have a clear beginning, middle, and end with regard to a process, users will not necessarily recognize their own successful (or unsuccessful) application of the information. Instead, SOP’s can be made more central in lab function by leveraging the experience of recent trainees. Their fresh awareness of carrying out the steps can shape the content into a more story-like format, thereby amplifying the power to connect with future users. In addition, unlike a template, this immediate navigation of the process tends to better focus the content on the most straightforward essentials. In our experience of producing and utilizing student-generated videos for instructional labs, we have observed the impact of these benefits. Our goal in this presentation is to identify and further explain those, based on human factors analysis, cognitive research, and instructional design principles, and to demonstrate how those aspects of procedural communication can be applied in making and utilizing SOP’s in academic research labs.
Encouraging Transparency in Lab Safety via Teachable Moments and Positive Fee...
Transparency is an essential part of developing and maintaining an ethical culture and a safety culture. We found two practices that significantly contributed to both - capitalizing on teachable moments and the active provision of detailed positive feedback. When we applied these to instances of evaluating performance, we found that they facilitated communication and supported the inquiry necessary to develop and sustain openness. While enforcement, an alternative approach, may evoke rapid compliance, it may also tend to reduce discussion. By contrast, we found that consideration of the vulnerability of those in non-compliance tended to ease the exchange and support the robust relations needed to create and maintain safe conditions. Appreciation for the state of intense interest and hunger for information characteristic of these teachable moments led to providing specific guidance that recipients were ready to use immediately. In addition, reinforcement of existing desirable practice via specific positive comments gave recipients the guidance necessary to build on their current foundation of skills, knowledge, and strengths. This presentation brings together research in neurological science, principles of management and evaluation, and cases of our observation to illustrate how performance evaluations can be leveraged to achieve an ethically responsive culture.
Formatting Lab Inspecction Feedback for Success
The format of feedback has a significant impact on the outcome of an evaluation. For example, checklists, a common tool in health and safety inspections, have limited potential to change practices and habits between utilizations because they don’t convey priority or provide guidance on how to solve cited issues and because there is variability in thoroughness of application. By contrast, feedback in the form of unstructured descriptive comment has the potential to magnify existing strengths which sustain overall good practice between inspections if the comments include positive citations that are specific and detailed. Without this addition to the standard, structured checklist, inspectors miss the opportunity to reinforce actions already being performed and the opportunity to build on the foundation of existing skill and knowledge. This presentation brings together principles of management, evaluation tool design, and neurological science to illustrate how to leverage inspection feedback for a more significant impact on the culture of safety.
Supporting a Culture of Safety with Teachable Moments
Recognizing teachable moments and transforming them into occasions of learning can be a useful strategy in developing a culture of safety in an academic department. Responding with recognition of the vulnerability of those experiencing undesired outcomes can open communication and support the inquiry necessary to develop and sustain safety changes. In this vulnerable state of momentary failing, people can experience intense interest in specific information that they are prepared to apply immediately. They are hungry to learn and thus teachable, meaning ready to actively construct new understanding. In addition, we discovered that once a teachable moment is met with support, people tend to initiate other inquiries rather than wait for their safety shortcomings to be discovered. Therefore, learning how to recognize and respond to teachable moments is an essential skill for safety officers to develop in pursuit of a self-regulating environment of good safety norms. Here, we present four short teachable moment case studies in order to demonstrate what qualities they have, how to utilize the opportunities provided by a user-driven approach, and what benefits can be anticipated from a partnership between students and the safety organization within an academic department.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
