Hybrid Learning Integrated Remote Laboratory: A Pedagogical Strategy for Future Practicum Learning

The hybrid learning integrated remote laboratory, an innovation in educational technology, is a practical and real-time solution that allows students to access and interact with laboratory equipment remotely via the internet network. This research aims to analyze the implementation and effectiveness of this model in an embedded systems practicum course. The study, conducted using a quasi-experimental method, involved 35 students in the experimental group and 36 in the control group. The learning model in the experimental group was implemented with a differentiated approach, allowing students to participate in face-to-face learning in the laboratory or attend online. The technology in this research was built with an interactive user interface in the form of an e-learning integrated remote laboratory application, providing online students with access to learning materials, discussion forums, assignments, chat, video conference, and an online microcontroller coding editor. The use of the online microcontroller coding editor empowers students to create programs and control physical equipment in the laboratory, such as Arduino modules, several sensors, and output devices, remotely and in real-time. Descriptive analysis and t-tests were used to analyze students’ comprehension of the embedded systems course. The test results showed a difference in the average academic achievement of students, with the learning outcomes of the experimental group students being higher than those of the control group. This model, therefore, demonstrates its impact on optimal and practical learning in the embedded system course.

Case Article—Budding with ERP: Information and Operations Management Challenges in a Nascent Industry

The role of analytics in operations and supply chain management (OSCM) has gained significant importance due to the decision-making complexities in the current business environment. The effectiveness of most analytical approaches, in turn, relies on access to timely and accurate data and information. Hence, it is essential for OSCM students to understand the underlying processes and dynamics of information management, for which enterprise resource planning (ERP) systems have become a standard. This case study can be a useful resource for introducing the critical interface between OSCM and information systems. The case study aims to facilitate learning on (1) the limitations of a rudimentary and disconnected information system, (2) the benefits and challenges of ERP implementation, and (3) the important steps to ensure a successful implementation of an ERP system. It provides an interesting context of a fast-growing agribusiness producing regulated products in Canada. The case study has been used in OSCM and management information systems (MIS) courses in two Canadian public Universities. Funding: This work was supported by Mitacs [Grants IT28747 and IT32722].

Determination of Permanent Deformations of Non-Cohesive Soils in Pavement Structures under Repeated Traffic Load

One of the main types of distress in pavement structures is rutting, which may also reduce serviceability significantly. Most design methods typically attribute rutting to the asphalt layer alone, proposing that it can be managed by controlling vertical deformation or stress at the subgrade’s top. Furthermore, these methods frequently lack precise measurements for rut depth. On-site measurements show that the majority of permanent deformation occurs in the unbound layers beneath the asphalt; attention should be directed towards these layers. In recent literature, there are calculation methods that account for accumulating strains in soils. However, further investigation is needed regarding the effect of soil properties and the significance of the pavement cross-section. The literature is also somewhat contractionary regarding the origin of permanent deformations. In this research, the residual settlement of soils (base, subbase, and subgrade) under flexible pavement systems was analyzed due to the repeated traffic loads. Rut depths were calculated and analyzed using the High-Cycle Accumulation (HCA) model. The different behaviour in each course of the pavement system is discussed to reveal their contribution to total ruts. The effect of the grain size distribution of the subgrade was analyzed, and its significance on the rutting depths was demonstrated. Standardized pavement cross-sections with different asphalt thicknesses were evaluated, and the calculated settlements of the pavement originating from the ground during the design lifetime are also presented. It is shown that, with the same number of repetitions, the settlements calculated in each traffic load class are proportional to the thickness of the asphalt course. The contribution of the base, subbase, and subgrade courses to the total settlement is also presented for different subgrade types and traffic load classes.

Implementation of the Fuzzy Mamdani Method in Decisions on Light Intensity in Plant Seed Research Rooms

This research is motivated by the assignment requirements of the intelligent systems course. Meanwhile, the title selection was based on the need for automatic regulation of the light intensity of the research lab room. The problem faced is that practitioners cannot regulate the light intensity at all times when there are changes in air temperature and humidity, then during the growth period the seeds must receive sufficient light so that seed growth can be maximized and can be predicted and managed well. This problem can be overcome one way by using the Fuzzy Mamdani method. The fuzzy mamdani method uses 3 variables, namely, input data, data rules, and output. The fuzzy input used in this research is the temperature and humidity values. The fuzzy rules applied are how the input value influences the output that will be produced. The output in this research is the size of the light intensity value. The use of the fuzzy application method is assisted by MATLAB Production Server R2015a 2.1 software. The fuzzy logic in the plant research room was successfully implemented and developed and produced accurate light intensity output, thereby helping practitioners to obtain optimal seeds. In this research, the Fuzzy Mamdani Method was used.

Investigating the Efficacy of a Virtual Reality-Based Testing Station of Flexible Manufacturing System: A Usability and Heuristic Evaluation

This study presents a comprehensive evaluation of a virtual reality-based testing station designed for flexible manufacturing systems. Given the intricate nature of flexible manufacturing systems and the demand for precision in learning, the integration of virtual reality emerges as a promising approach to enhance both student competence and engagement. By employing a combined assessment with the System Usability Scale and heuristic evaluation conducted by 36 students and 5 experts, respectively, the virtual reality-based testing station achieved an average usability score of 72.78, indicating good usability. Noteworthy heuristic challenges, particularly in the domains of ‘Realistic Feedback’ and ‘Navigation and Orientation Support,’ have been identified, providing valuable insights for potential refinements to the testing station. The outcomes of this study not only guide immediate improvements but also pave the way for future research endeavors aimed at elevating the learning outcomes in flexible manufacturing systems courses.

Perception-Dominant Control Types for Human/Machine Systems

We explore a novel approach to complex domain modelling by emphasising primitives based on perception. The usual approach either focuses on actors or cognition associated with tokens that convey information. In related research, we have examined using effects and/or outcomes as primitives, and influences as the generator of those outcomes via categoric functors. That approach (influences, effects) has advantages: it leverages what is known and supports the expanded logics we use, where we want to anticipate and engineer possible futures. But it has weaknesses when placed in a dynamic human-machine system where what is perceived or assumed matters more than what is known. The work reported here builds on previous advances in type specification and reasoning to ‘move the primitives forward’ more toward situation encounter and away from situation understanding. The goal is in the context of shared human-machine systems where: • reaction times are shorter than the traditional ingestion/comprehension/response loop can support; • situations that are too complex or dynamic for current comprehension by any means; • there simply is insufficient knowledge about governing situations for the comprehension model to support action; and/or, • the many machine/human and system/system interfaces that are incapable of conveying the needed insights; that is, the communication channels choke the information or influence flows. While the approach is motivated by the above unfriendly conditions, we expect significant benefits. We will explore these but engineer toward a federated decision paradigm where decisions by local human, machine or synthesis are not whole-situation-aware, but that collectively ‘swarm’ locally across the larger system to be more effective, ‘wiser’ than a convention paradigm may produce. The supposed implementation strategy will be through extending an existing ‘playbooks as code’ project whose goals are to advise on local action by modelling and gaming complex system dynamics. A sponsoring context is ‘grey zone’ competition that avoids armed conflict, but that can segue to a mixed system course of action advisory. The general context is a costly ‘blue swan’ risk in large commercial and government enterprises. The method will focus on patterns and relationships in synthetic categories used to model type transitions within topological models of system influence. One may say this is applied intuitionistic type theory, following mechanisms generally described by synthetic differential geometry. In this context, the motivating supposition of this study is that information-carrying influence channels are best modelled in our challenging domain as perceived types rather than understood types.

PSII-10 Development of an interdisciplinary undergraduate and graduate course in precision livestock farming systems

Abstract The modern livestock industry is increasingly adopting data, technologies, and automation into daily husbandry and management routines and decisions. These advances in precision livestock farming (PLF) enable improved financial margins, sustainability, efficiency, and animal productivity and welfare. However, there is currently a gap between the engineers and data scientists designing the technologies and the animal scientists and caretakers using them. At North Carolina State University a novel course on PLF Systems for undergraduate and graduate students was developed in the Department of Animal Science. Through lecture delivery, livestock production scenarios, scientific literature, and data-based homework assignments students explored data collection, management, analysis, and data-based decision making. Students gained hands-on experience with a variety of sensor types and signal processing through lab-based activities. Basic hardware and software development concepts were explored during an Arduino-based microcontroller activity. The course was developed and refined using student feedback to include additional sensor and lab-based days and additional in-class supported activities utilizing Excel for data manipulation, processing, and presentation. Self-reported student learning results were collected across two semesters (19 students; 18 Animal Science, 1 Biological Engineering) with84% of students indicated the course was effective in increasing their ability to evaluate and implement technology in livestock production systems and 74% of students reported increased knowledge of coding and software, as well as their ability to clean, analyze, and make sense of raw data. The topics and delivery methods implemented in this course could inform the basis for development of similar interdisciplinary PLF courses at other academic institutions.

Exploration of Teaching Styles in a Digestive System Integration Course

Purpose: To explore the innovation of teaching methods in digestive system courses and its application effect in the context of curriculum integration. Methods: 60 undergraduate majors of digestive system diseases in the class of 2023 (orientation) of our hospital were divided into 30 students each in the general class and the experimental class using the random grouping method. The general class adopted the case-based learning (CBL) teaching mode, and the experimental class adopted the integrated course mode of CBL + “organ-systems-based curriculum” (OSBC). The teaching effects of the two classes were compared through basic theory and clinical five-station examination. Results: The differences in the basic theory scores and excellence rates of the students in the experimental class were significant (P < 0.05); the clinical 5-station examination suggested that there was no statistical significance in the physical examination of the two classes (P > 0.05); and the differences in the scores of the clinical questioning, case writing, auxiliary examination, and oral examination of the two classes were statistically significant (P < 0.05). Conclusion: The teaching method based on CBL + OSBC integrated course is effective in the teaching reform of the digestive system course and has popularization value.
