16. Representing Learning Designs in a Design Support Tool

Author

Zalavra, Eleni, Papanikolaou, Kyparisia, Dimitriadis, Yannis, and Sgouropoulou, Cleo

Abstract

Learning Design (LD) research accounts for several design support tools, or LD tools, employing representations for learning designs to facilitate the "teachers as designers" thinking while preparing learning experiences. In contrast to existing studies having followed mainly a specialist/researcher (as opposed to a teacher) perspective, our quest to develop an LD tool follows a Design-Based Research (DBR) approach involving practitioners. Specifically, in this paper, we attempt to give voice to teachers as designers and investigate how they prefer having their learning designs represented by LD tools. Aiming to create a principled account of how to represent learning designs in an LD tool, we first conducted an integrative literature review to formulate a representational framework that drove our research. Subsequently, we addressed the following LD representational dimensions: (1} format, (2) organisation, (3) guidance and support, and (4) contextualisation. We are reporting on a case study conducted with 16 participants in a teacher education context. Although previous research typically reported findings based on a single LD tool's evaluation over a short period, we have opted for eliciting feedback based on a rich LD experience. To this end, we acquainted participants in LD projects with two LD tools (Learning Designer and WebCollage) during an academic semester. Furthermore, we followed a mixed-method explanatory sequential design applied through a survey questionnaire and semi-structured interviews to achieve a more profound consideration of the teachers' preferences for LD representations. Our findings indicate that the teachers strongly endorse an LD tool supporting a visual format and a global organisation in the form of a table that provides a global overview of a learning design while focusing on its specific elements. Teachers seem to prefer an LD tool that balances providing guidance and flexibility, as they opt for (1) a non-restrictive taxonomy for articulating learning objectives, (2) some form of standardisation for formatting learning units, along with allowing free formation, (3) a flexible pedagogical framework for modelling the learning activities' pedagogy so that it can be adjusted to particular designers' needs, and (4) a typology of technologies that can be utilised or not. In addition, they seemed to favour an LD tool supporting high contextualisation, as they prefer to describe contextual details for a learning design's units and activities. These findings constitute design principles for our ongoing DBR and may stimulate momentum for researchers developing LD tools.

25. Exploration of Augmented Reality in Spatial Abilities Training: A Systematic Literature Review for the Last Decade

Author

Papakostas, Christos, Troussas, Christos, Krouska, Akrivi, and Sgouropoulou, Cleo

Abstract

This review paper presents a systematic literature review on the use of Augmented Reality (AR) in engineering education, and specifically in student's spatial ability training, for the last decade. Researchers have explored the benefits of AR, and its application has been of increasing interest in all levels of education. Engineering students tend to have difficulties in acquiring visualization skills, and hence, AR is gaining momentum in enhancing students' learning achievements. This paper aims to present valuable information to researchers, tutors and software developers of learning technology systems concerning the advantages and limitations of AR in spatial ability training, the incorporation of adaptivity and personalization in AR applications as well as the aspects of spatial ability having been evaluated using AR and the prevalent evaluation methods for AR applications. To this direction, a total of thirty-two (32) studies were reviewed, having been published since 2010. The findings reveal an increase in the number of studies during the last three years. One major conclusion is the improvement of learners' spatial ability using AR in educational settings, and the noted challenge is the need for more learning content. One research gap that has been identified is the lack of personalization in the developed applications, offering space for future research. Concluding, this area is under-researched, and thus, there is scope for a lot of improvement.

26. Collaborative Activities Recommendation Based on Students' Collaborative Learning Styles Using ANN and WSM

Author

Troussas, Christos, Giannakas, Filippos, Sgouropoulou, Cleo, and Voyiatzis, Ioannis

Abstract

Computer-Supported Collaborative Learning is a promising innovation that ameliorates tutoring through modern technologies. However, the way of recommending collaborative activities to learners, by taking into account their learning needs and preferences, is an important issue of increasing interest. In this context, this paper presents a framework for providing recommendations of collaborative activities to learners by employing an Artificial Neural Network (ANN) and the Weighted Sum Model (WSM). In our approach, the Gardner and Korth framework is employed to identify the dimensions of the learners' collaborative learning styles. For each dimension, different weights are assigned and used as input data for the ANN. Then, the WSM and the activation function determine the output vector by mapping the resulting values. The final output of the ANN is a different percentage of collaborative activities in which learners can participate. This output is used to recommend the activities to the learners. As a testbed for our research, we have developed an intelligent tutoring system for the programming language "Java". Our system was evaluated using an established framework and the statistical hypothesis test. The results show a high degree of pedagogical affordance and usefulness of our approach as well as its positive impact on learning.

Author

Giannakas, Filippos, Troussas, Christos, Krouska, Akrivi, Sgouropoulou, Cleo, and Voyiatzis, Ioannis

Abstract

Working in groups is an important collaboration activity in the educational context, where a variety of factors can influence the prediction of the teams' performance. In the pertinent bibliography, several machine learning models are available for delivering predictions. In this sense, the main goal of the current research is to assess 28 different machine learning models, including a Deep Neural Network (DNN) which is structured by 4 hidden layers, for predicting teams' performance. Additionally, both data analysis and optimization of input data are also explored for their effectiveness in the improvement of the models' performance. One key finding of the present study is that the XGBoost model succeeded better prediction results, and its precision and robustness were found to be higher, compared to the other models. Additionally, data optimization was shown to be an essential procedure, since the prediction accuracy of all the models, and specifically, that of the XGBoost, improved and found to be 96% during the first phase that of the process, and 94% during the second phase that of the product. Similarly, after applying the hyperparameter tuning and data optimization, the prediction accuracy of the DNN was also improved and found to be 89.94% and 86.16%, during the same two phases. Finally, for interpreting the output of the ML models, in terms of features' importance, the Shapley Additive Explanations framework (SHAP) was used.

Author

Papakostas, Christos, Troussas, Christos, Krouska, Akrivi, and Sgouropoulou, Cleo

Abstract

The integration of Augmented Reality (AR) in welding training is considered to increase the efficiency, security and time gain in operations, reducing consumable and infrastructures costs. Prior research has examined the integration of AR-simulation in applications, like medical operations or aviation, showing the need for greater usability of these systems. However, research on AR integration in welding training is yet limited. It can help new welders learn effectively and be prepared to work in the industry. The motivation of this study was the ongoing use of AR in manufacturing training and its novelty is the analysis of the most significant factors affecting the actual AR system use. The main objective of this research is to evaluate the use of AR technology in welding training using an innovative model, appropriately extended to consider pedagogy and technology. The contribution of this paper is the exploration and understanding of the factors associated with the AR welding training which can lead to goal fulfillment and, subsequently, impact users' choice. This study is based on a modified Technology Acceptance Model, extending it by two external variables (perceived enjoyment and system quality) and the sample is 200 trainees. The findings show that the external variables are predictors of perceived usefulness and ease of use. The intention to use AR simulator is positively influenced directly by system quality and perceived ease of use. The findings help AR developers enhance the quality of AR-simulation training systems to enhance users' experience and their behavioral intention to use them.
