Integrated Data Processing Architecture Applied to Learning Objects Repository for Educational Robotics: Proposing Approach

Educational Robotics has emerged as a multidisciplinary field integrating Information and Communication Technologies, Engineering, and Artificial Intelligence areas in education. Furthermore, Educational Robotics offers an innovative approach to teaching and learning by incorporating the construction and programming of robots. However, the small number of platforms for sharing Educational Robotics Learning Objects with a large amount of well-described metadata poses a challenge for efficient search and retrieval of relevant educational content. This study presents an architecture for data processing and ingestion in the RepositORE system, a Learning Objects Repository for Educational Robotics that stores educational content and associated metadata based on the Dublin Core standard. Based on microservices architecture, the proposed system aims to facilitate the location and reuse of learning objects by adapting the RepositORE system to work as a client service. The theoretical framework explores the concepts of learning objects, repositories, and the significance of Educational Robotics in education, and reviews related works. The proposed architecture and system can potentially enhance the accessibility and discoverability of Educational Robotics Learning Objects, fostering effective teaching and learning experiences.

Co-Design of a Reusable Learning Object (RLO) to Address Caregiver Responsive Infant Feeding Behaviours (CRIB) to Prevent Childhood Obesity: A Mixed-Method Protocol.

Responsive infant feeding is a key strategy for childhood obesity prevention. Responsive feeding involves caregivers responding to infant hunger and satiety cues in a timely and developmentally appropriate manner. There is a dearth of evidence-based information and guidance for caregivers on how to responsively feed their infants. The aim of this research is to co-design a Reusable Learning Object (RLO) and guidance infographic to improve caregiver awareness, understanding and use of responsive infant feeding behaviours. The Capability, Opportunity, Motivation and Behaviour (COM-B) model of behaviour change and the Aim, Storyboarding, Populate specification, Implement media, Review and release prototype, and Evaluate (ASPIRE) approach for digital intervention co-design will be utilised. Four co-design workshops with caregivers of infants and healthcare professionals (HCPs) will determine priority RLO content. Content analysis will enable RLO development and process reporting. Formative and summative surveys will be conducted to evaluate the usability of the RLO, its impact on caregivers and its potential implementation into NHS care pathways. The output will be a RLO on responsive feeding for caregivers and an infographic for HCPs/support workers which will contribute to a future obesity prevention intervention. The findings will be disseminated to stakeholders and submitted for publication in a peer-reviewed journal.

Maximizing reusability of learning objects through machine learning techniques

Maximizing the reusability of learning objects through machine learning techniques has significantly transformed the landscape of e-learning systems. This progress has fostered authentic resource sharing and expanded opportunities for learners to explore these materials with ease. Consequently, a pressing need arises for an efficient categorization system to organize these learning objects effectively. This study consists of two primary phases. Firstly, we extract metadata from learning objects using web exploration algorithms, specifically employing feature selection techniques to identify the most relevant features while eliminating redundant ones. This step drastically reduces the dataset’s dimensionality, enabling the creation of practical and useful models. In the second phase, we employ machine learning algorithms to categorize learning objects based on their specific forms of similarity. These algorithms are adept at accurately classifying objects by measuring their similarity using Euclidean distance metrics. To evaluate the effectiveness of learning objects through machine learning techniques, a series of experimental studies were conducted using a real-world dataset. The results of this study demonstrate that the proposed machine learning approach surpasses traditional methods, yielding promising and efficient outcomes for enhancing learning object reusability.

Promoting formative assessment practices in senior phase mathematics classrooms using meaning equivalence reusable learning objects

South African mathematics teachers in the Senior Phase (Grades 8 and 9) were introduced to the pedagogical tool, meaning equivalence reusable learning objects (MERLO), as a formative assessment (FA) strategy to promote and support teachers’ professional growth in using FA practices in the classroom. The cultural-historical activity theory (CHAT) and meta-didactical transposition (MDT) were used to frame the evolution process of teachers’ praxeologies. In this study we used qualitative participatory action research that encompassed 3 phases: pre-MERLO phase, MERLO workshop and post-MERLO phase. The study was conducted in the northeast of Pretoria in the Tshwane district in the Gauteng province, South Africa. Twelve Senior Phase mathematics teachers were purposively sampled in 6 public schools before the workshop training. During the workshop training, only 5 teachers participated due to the COVID-19 outbreak. The data collection techniques included pre- and post-interviews, workshop training sessions, classroom observations, field notes, teachers’ reflective journals, teachers’ lesson plans, learners’ workbooks and learners’ worksheets, and data were analysed using thematic analysis. The findings reveal that the teachers acquired adequate knowledge and skills to effectively structure and integrate the lesson plan of teachers’ didactical praxeologies as FA activities into their mathematics classrooms. The findings also reveal that the learners showed more interest and motivation, were actively involved, developed a deeper understanding of mathematics content, and showed increased autonomy in learning. Future research could involve implementing MERLO in all South African provinces and introducing MERLO to other emerging countries. However, the findings of this study are based on a limited sample of teachers and schools, and the recommendation is that, for future studies, more teachers should be involved in the MERLO professional development.

A blended learning perineal suturing programme for midwifery students: An evaluative descriptive study

AimThe purpose of this study was to examine midwifery students' views and experiences of learning perineal suturing skills through a blended learning approach. BackgroundEvidence suggests that not all midwifery students are gaining sufficient experience in perineal trauma and suturing to sufficiently prepare them to achieve competency in this skill at the point of registration. DesignThe blended learning approach included lectures, a bespoke ‘suture at home kit’, online reusable learning objects, and an optional face-to-face drop-in suture clinic. Midwifery students submitted a video demonstration of the skills acquired and then attended a clinical skills laboratory in preparation for a face-to-face competency assessment on campus. ResultsA qualitative descriptive evaluation research design study was undertaken from 22 participants. Deductive thematic analysis was selected to analyse the qualitative data.Two themes were identified. The first theme, 'learning at home', included sub-themes of 'deliberate practice' and 'the ability to make mistakes. The second theme, 'achieving competency', included sub-themes of 'equipment' and 'bringing it all together' ConclusionsThe blended learning approach of the programme applied to teach perineal suturing had a positive influence on midwifery students learning of the skill. The acquisition of knowledge using the suture at home kit gave the students confidence and prepared them for laboratory practice and assessment, and ultimately prepared them for practice placement. They identified other clinical skills suited to using an 'at home' simulation pack. The validation of the perineal suturing programme by midwifery students supports the need for a blended learning approach for this and other clinical skills. All participants expressed a positive view of the programme and found it beneficial for their learning. Midwifery students recognised that the suture at home kit gave them confidence, knowledge of the skill and preparedness for the clinical skills laboratory practice and assessment. They identified other clinical skills suited to using an 'at home' simulation pack. The positive experiences of midwifery students in this study to a blended-learning programme for perineal suturing education and training further validated the recognised need to develop and include online, and face to face learning approaches for this vital aspect of intrapartum care.

Supporting Open Education through a Coordinated Network of Support

In this article, Montgomery College discusses the adoption of H5P, a free and open-source content collaboration framework based on JavaScript that was used in substitute paid practice opportunities for students in Spanish 101 and 102. Utilizing a participatory action research model, three faculty and 47 students collaborated to inform the design, development, and refinement of H5P RLOs designed to meet institutional goals through targeted student practice. Results of the faculty-student collaboration demonstrated a high level of satisfaction (4.54 average rating out of five) and practicality and usefulness of the H5P practice materials as a viable tool that helped them achieve success in their courses (89%). This work led to the development of the Maryland H5P Collaborative Network (Network) co-launched in partnership with the Community College of Baltimore County in 2021. The Network brings together over 250 educators from 40 different institutions across the United States to share best practices and action research in support of Open Educational Resources (OERs) and Reusable Learning Objects (RLOs).

Effective communication of learning intentions and success criteria in the mathematics classroom: MERLO pedagogy for Senior Phase South African schools

A well-designed assessment construct is critical for improving all aspects of quality education and validating the achievement of educational reform. The global prevalence of how teachers communicate learning intentions (LIs) and success criteria (SC) has been of great concern, particularly in the South African context. This study investigates how Meaning Equivalence Reusable Learning Objects (MERLO) pedagogy effectively transforms Senior Phase mathematics teachers’ daily practice in the classroom. The study adopted qualitative participatory action research to frame the evolution of teachers’ praxeologies such as teachers’ meta-didactical and didactical praxeologies, to improve teachers’ beliefs and practices to integrate MERLO pedagogy as assessment activities. Twelve Senior Phase teachers were purposively selected in Gauteng, South Africa. The methods used for data generation were interviews, classroom observation, document analysis, field notes and training sessions. Thematic analysis was used to obtain insight into teachers’ beliefs and practice of effectively communicating LIs and SC in the classroom. At the initial stage, teachers were examined with regard to their beliefs and practices of assessment practices in the classroom, which informed MERLO intervention. In the second stage, teachers were asked to learn about MERLO items by reading the MERLO handout provided to them, participating in the workshop and sharing their opinions and views with others. In the third stage, teachers had to design MERLO assessment items on their own to assess learners’ level of understanding of the mathematical concepts in Senior Phase. The findings revealed that the participating teachers acquired adequate knowledge and skills on MERLO techniques that allowed them to structure and integrate the lesson plan of assessment activities into their mathematics classrooms. This study contributes to the body of knowledge by introducing MERLO pedagogy to Senior Phase South African mathematical teachers as an assessment strategy. COVID-19 caused some teachers to drop out of the study after the pre-MERLO participation phase and, accordingly, future research suggests that more teachers be included in similar studies.

A reusable learning object for assessment cardiovascular and respiratory responses.

Produce and determine the validity of a reusable learning object for assessment cardiovascular and respiratory responses from the taxonomy of the North American Association of Nursing Diagnosis Domain 4. Activity/Rest, Class 4. Cardiovascular/Pulmonary Responses. A descriptive methodological study was developed that included three phases (1) construction of the reusable learning object incorporating Gagné's nine instructional events, (2) content validation was carried out with 24 nurses who served as experts, and (3) and Usability was evaluated by 22 nursing students from a Public University in Colombia. The reusable learning object was organized into three modules: introduction, assessment of cardiovascular responses, and assessment of pulmonary responses. The learning object obtained a content validation index of 0.86; the usability indicators had proportions of agreement greater than 85%. The reusable learning object is valid and can be used for teaching the assessment of cardiovascular and respiratory responses in nursing students.

Utilizing Co-Creative Principles to Develop an E-Learning Platform for Interprofessional Training on Tinnitus: The Erasmus+ Project Tin-TRAC.

Tinnitus treatment, diagnosis and management across Europe varies significantly. The lack of national clinical guidelines for tinnitus management in most European countries and the absence of a common language across all disciplines involved is reflected in the diversification of healthcare practices. Interprofessional Training for Tinnitus Researchers and Clinicians (Tin-TRAC) is an Erasmus+ project that aims to develop common educational ground in the form of an e-Learning platform, co-created by patients, researchers and clinicians, which is able to unify tinnitus diagnosis and treatment strategies across Europe. A pan-European thematic educational platform integrating the best practices and latest research achievements with regard to tinnitus diagnosis and management has the potential to act as a facilitator of the reduction of interdisciplinary and interregional practice diversification. A detailed analysis of the educational needs of clinicians and researchers across disciplines will be followed by the co-creative development of the curriculum. Reusable learning objects will incorporate the training contents and will be integrated in an open e-Learning platform. Tin-TRAC envisions that its output will answer the need to create a common language across the clinicians and researchers of different disciplines that are involved in tinnitus management, and reduce patients’ prolonged suffering, non-adherence and endless referral trajectories.

SG-LOM as Metadata Description for Serious Games to Benefit from LMS Monitoring Features

Compared to the conventional approach of e-learning, serious games are playing an increasingly important role in the educational sphere and reached a certain maturity to become a possible alternative to traditional methods of learning that is often seen as restrictive and boring sometimes by learners. This is due to the fact that young people today are familiar with new technologies and virtual worlds outside schools as part of their leisure. A habit that enable these young people to be immediately in the heart of the matter since they already have a video game culture (gameplay) that allows them to focus on the main message. However, the integration of serious games in the learning process still limited since they don’t provide efficient features for monitoring and assessing learner (player) interactions and decisions without breaking the nonlinearity of the game in order to show them the consequences of their decisions, a limit that has been proven in a previous comparative study [1].
 In this paper we address the aspects of serious games (Robocode as example) integration and deployment into LMS (Dokeos as example) based on the automatic packaging and exportation of serious games as reusable learning objects (LO) that can be easily distributed through any LMS. This integration uses the ADL SCORM data model that defines how content may be packaged as a Package Interchange File (PIF), and the IEEE LOM Application Profile “SG-LOM” [2] as metadata description to describe every level of SCORM since the standard LOM doesn’t meets the particular needs of serious games.

Connecting Students’ Interests to a Learning Context: The Case of Ecosystem Services in STEM Education

Interest in a subject matter is a powerful motivation in education. Prior knowledge of students’ interests can be helpful in teaching the concept of ecosystem services (ES) and disservices (ED), which is increasingly being used in science, technology, engineering, and mathematics (STEM) education, including soil science. Study objectives were to evaluate prior students’ soil science-related interests and use them to expand the learning context of a laboratory exercise on soil reaction (pH) with ES/ED in an online introductory soil science course (FNR 2040: Soil Information Systems) taught at Clemson University. Students from multiple fields of study (environmental and natural resources, forestry, and wildlife biology) completed the laboratory exercise in Fall 2021. This exercise on soil regulating and provisioning ES/ED included a sequence of reusable learning objects (RLOs), which are self-contained online modules frequently used for e-learning. Laboratory activities included calculating the liming replacement cost of soil inorganic carbon (SIC) and avoided social cost of carbon (SC-CO2) from soil inorganic carbon (SIC) stocks in the assigned soil. The laboratory exercise was effective in increasing the familiarity with the concept of ES/ED (+39.4 increase in “extremely familiar” category) and the concept of SIC (+44.7 increase in “moderately familiar” category). The graded online quiz consisted of 9 questions and was taken by 55 students with an average score of 7.0 (out of 9). A post-assessment survey found that the laboratory was an effective way to learn about soil pH, SIC, and their ES/ED. Detailed student comments showed learning enjoyment (e.g., calculations, good experience), the value of multimedia (e.g., video, PowerPoint), the learning flexibility (e.g., separate parts), content applicability (e.g., economic values of services), and constructive criticism (e.g., clearer instructions, lots of information). A word cloud based on comments by the students about their soil ES laboratory exercise experience indicated the most common words submitted by students to describe their experience, such as “soil”, “calculations”, “enjoyed”, “learning”, and “values”, among others. Applied recommendations are proposed to develop future exercises based on the alignment of students’ interests, STEM subject matter, and ES/ED applications.

Teaching Innovation in STEM Education Using an Unmanned Aerial Vehicle (UAV)

The use of unmanned aerial vehicles (UAVs) has increased in the science, technology, engineering, and mathematics (STEM) professions. This means there is a growing need to integrate UAV training into STEM education. This study aimed to develop and evaluate a UAV education module and laboratory exercise for natural resource science students. The study used a series of reusable learning objects (RLOs) to assess students’ prior knowledge of remote sensing and UAVs. Students were taught the steps of UAV data acquisition and processing through lectures and UAV simulation videos. Students applied this knowledge by completing a laboratory exercise that used previously collected UAV data. Student knowledge retention and understanding were evaluated using an online quiz to determine the effectiveness of the education module. The average quiz score was 92%, indicating that the UAV laboratory exercise effectively taught students about UAV data acquisition and processing for natural resource research. Overall, students expressed positive opinions about the UAV education module. Student feedback indicated that the laboratory exercise was engaging, but some students would have preferred a hands-on experience for some parts of the exercise. However, in-person UAV instruction may not be accessible for all educators because of UAV cost or lack of instructor training. This study provides educators with crucial recommendations for designing UAV exercises to improve access to UAV-related educational content. This study indicates that online training can effectively introduce students to UAVs. Given the wide range of UAV uses across STEM fields, students in many STEM disciplines would benefit from UAV education.

Teaching Field Data Crowdsourcing Using a GPS-Enabled Cellphone Application: Soil Erosion by Water as a Case Study

Crowdsourcing is an important tool for collecting spatio-temporal data, which has various applications in education. The objectives of this study were to develop and test a laboratory exercise on soil erosion by water and field data crowdsourcing in an online introductory soil science course (FNR 2040: Soil Information Systems) at Clemson University. Students from different STEM disciplines (wildlife biology, forestry, and environmental and natural resources) participated in the study in the fall of 2021. They completed a sequence of self-contained digital teaching modules or reusable learning objects (RLOs), which are often used in online learning. The exercise included a field exercise and learning module to teach students about different types of water-based soil erosion as well as field data collection and crowdsourcing tools. As a result of this exercise, student familiarity with crowdsourcing was effectively increased, as shown by the post-assessment survey with a +31.2% increase in the “moderately familiar” category and a +28.3% increase in the “extremely familiar” category. The online quiz contained ten questions and was taken by 56 students with an average score of 9.5 (out of 10). A post-assessment survey found that most of the students indicated that the laboratory was an effective learning experience about field data crowdsourcing using a GPS-enabled cellphone application. Detailed students’ comments indicated enjoyment of learning (e.g., data collection, learning about different technologies), the value of multimedia (e.g., ArcGIS Survey123, cellphone), the flexibility of learning (e.g., field work), the content applicability (e.g., actual field examples of erosion by water), and criticism (e.g., technical issues). A word cloud derived from students’ comments about their laboratory exercise experience indicated the most frequent words used by students, such as “erosion”, “enjoyed”, and “different”, among others. Incorporating a learning module and field exercise using modern data collection technology into an undergraduate soil science education course enabled students to understand the value and methods for leveraging cellphone-based field collection methods to crowdsource data for environmental assessment. Practical recommendations for planning and executing future crowdsourcing exercises were developed using the current study as an example.

Virtual Reality in Initial Teacher Education (VRITE): a reverse mentoring model of professional learning for learning leaders

ABSTRACT This small-scale design-based study describes a cyclical model of professional learning between three stakeholders in initial teacher education (ITE) namely: university-based educators (UEs), student teachers (STs) and co-operating teachers (CTs). This model promotes the development of digital learning leaders through an innovative mentoring process. This process started with university-based educators (UEs) mentoring their student teachers (STs) in the pedagogical use of Virtual Reality (VR) and the creation of re-usable learning objects (RLOs). STs were supported and encouraged to cascade this learning to their placement schools as digital learning leaders connecting the innovative practice from the university directly to their classroom practice. Through bi-directional reverse-mentoring the STs and CTs supported each other technically (with the VR) and pedagogical (through the links to the curriculum) to create additional subject-specific RLOs which the STs were able to demonstrate to the UEs on their return to university. Thus, providing the final link in the cycle of learning leaders across the triad of partners in ITE.

Development and piloting of an instructional video quality checklist (IVQC)

Purpose Medical education instructional videos are more popular and easier to create than ever before. Standard quality measures for this medium do not exist, leaving educators, learners, and content creators unable to assess these videos. Materials and methods Drawing from the literature on video quality and popularity, reusable learning objects, and multimedia and curriculum development principles, we developed a 26-item instructional video quality checklist (IVQC), to capture aspects of educational design (six items), source reliability (four items), multimedia principle adherence (10 items), and accessibility (six items). Two raters applied IVQC to 206 videos from five producers across topics from two organ systems (cardiology and pulmonology) encompassing four disciplines (anatomy, physiology, pathology, and pharmacology). Results Inter-rater reliability was strong. According to two-rater means, eight multimedia items were present in over 80% of videos. A minority of videos included learning objectives (46%), alternative language translations (41%), when the video was updated (40%), analogies (37%), or references (9%). Producer ratings varied significantly (p < .001) across 17 of 26 items. There were no significant differences according to the video topic. Conclusions IVQC detected differences in elements of instructional video quality. Future work can apply this instrument to a broader array of videos and in authentic educational settings.

Case Study: Decolonising the Curriculum – An Exemplification

Coventry University has made a strategic commitment to address the dimension of ‘race’ in its learning and teaching. Central to this is the establishment of a cross-institution curriculum change initiative called ‘Curriculum 2025’. The case study shared here details how we are approaching this task and some early reflections. Two things are explained: first, the provision of resources for staff who want to learn more about possible actions to take; second, our approach to working alongside course teams on new materials, often designed as reusable learning objects. An example of such a learning object is discussed which uses Wikipedia to enable students from diverse backgrounds to examine critically academic texts, books and other resources to understand how their learning may be skewed in favour of Western-originated thought and to identify alternative perspectives. The student activity also provides a co-creation opportunity, in that students are discovering the curriculum for themselves.

Relevant Influence of Semantic Web Framework on Smart E-Learning Environment

E-Learning systems have unbound prospects to deliver unmatched effective learning services and feedback assistance than what it is presently offering through mediums like online tutoring, or other electronic educational management services. Different stages and application potentials of Semantic Web technology and it’s architecture can be applied at different sectors and phases of the E-Learning framework to amplify the quality and versatility of services. Features of Semantic Web have been explored in the sectors with respect to instructors to plan, analyse and execute their tasks and also in making a sustainable system that interprets the structure of distributed, self organized, and self-instructed online learning to monitor it’s influence on performance. The main objective of this work is to study how electronic and online learning frameworks can be improved and enhanced by the influence of semantic web technologies in understanding and simplifying concept clarification and description, reusable learning objects (LOs), and benefits of the applying ontology in describing the learning materials for a better and more efficient learning system.

Usability and value of a digital learning resource in nursing education across European countries: a cross-sectional exploration

BackgroundHigher education is responsible for providing education that meets international benchmarks relevant to the needs of the international community. Due to the increase of digital tools in higher education, the possibility of sharing learning resources across nations has expanded. In the current project, a Norwegian university invited universities in Spain and the United Kingdom to adapt and translate e-learning resources originally developed for Norwegian nursing students for use within their respective Bachelor in Nursing programmes.AimThe aim of the current study was to gain insights into the usability and value for learning of e-compendiums shared and implemented across three European universities.MethodsThe study adopted a descriptive cross-sectional design and included nursing students from the University of Nottingham, Valencia Catholic University, and the University of Stavanger. Data were collected in Autumn 2017 through a questionnaire adapted from the validated “Centre for Excellence in Teaching and Learning Reusable Learning Object evaluation questionnaire” The questionnaire consisted of 19 items that included two aspects: e-compendiums’ value for learning and e-compendiums’ usability. The different study sites were compared using a binary logistic regression analysis. Subgroups of students were compared based on their gender and age.ResultsA total of 480 nursing students participated in the study. The e -compendiums were overall positively rated, especially for reinforcing and retaining knowledge. Compared to the students from the University of Stavanger, students from Valencia Catholic University rated the e-compendiums more positively in most aspects of learning. Students from University of Nottingham found the e-compendiums to be more important for learning engagement compared to students at the Norwegian study site, and no differences were found in any other aspects of learning. Younger students rated the interactivity and visual components as more important compared to older students.ConclusionsStudents from the University of Nottingham and Valencia Catholic University seem to accept the e-compendiums despite the fact that they were originally developed for use in another country. We argue that, when sharing e-learning resources across countries, an adaptation and translation process that includes a multicultural and multidisciplinary perspective should be carried out.

The application of reusable learning objects (RLOs) in preparation for a simulation laboratory in medication management: An evaluative study

To enhance the preparedness of undergraduate nursing and midwifery students to participate in the safe provision of medication administration on their clinical placements, an innovative blended learning strategy was designed and developed by the authors. The blended learning strategy included a suite of online reusable learning objects specific to medication management theoretical knowledge and psychomotor skills to prepare students for a 90-minute practical face to face simulation laboratory session. Students identified that the reusable learning objects had prepared them for the simulation laboratory session and was rated as a productive learning experience. The blended learning strategy implemented to teaching and learning medication management to undergraduate nursing and midwifery students can positively influence students’ acquisition of knowledge and psychomotor skills to safely administer medications prior to their practice placements in a clinical setting.

Supporting Healthcare Integration of Refugees Exploiting Reusable Learning Objects: The ASPIRE Framework.

The significant increase of refugees' migration has demonstrated an overwhelming need for their access and integration to healthcare systems. E-learning, especially in the form of experiential digital learning, has been highlighted as an important ally in supporting refugees' health needs. This paper aims to discuss the design and development process of Reusable Learning Objects (RLOs) to enhance digital health applications for refugees and integrate them to healthcare systems. The participatory approach based on the "ASPIRE" framework was followed. Using the "ASPIRE" process, 9 stakeholders were involved in the first phase of the development process, where a co-creation storyboarding workshop was held in Greece by the Medical Physics Laboratory of the Aristotle University of Thessaloniki. Essential qualitative and quantitative feedback was collected from stakeholders through an online questionnaire administered in Google Forms. Overall, enlightening ideas were expressed and all stakeholders commented positively on the value and efficacy of the workshop.
