A framework for data collection, analysis and evaluation of the relationship between students’ computer interaction and course grades in laboratory courses

Big data is an emerging topic, with huge investments in IT and education worlds. Together with awareness of the knowledge discovery and education improvement progresses, big data concept has come with a growing consciousness. There are several educational data mining analysis methods created, evaluated and presented in the literature in this manner. But, how the educational big data for finding “intelligently” valuable results to benefit students, teachers and administrators will be collected, filtered and handled? In this study, a unique data collection, filtering and evaluation framework for educational data mining was designed, evaluated and presented. In this perspective, an IT infrastructure and process monitoring software for gathering client computers’ data of 3 laboratories in a public high school was developed. Time series big data was collected during 5 months from 62 computers with this back stage working software. After filtering this data with eligible methods, resultant data was evaluated with Pearson’s correlation analysis between students’ rate of interactions with computers and their exam grades on laboratory courses. Results showed that students’ computer interaction and their success in the courses are highly correlated.

Towards a domain model for integrating competence frameworks into learning platforms

Since adoption of the Europe-wide university-reform called Bologna Process, each accredited study path, module, or course has to be provided with a summary of the conveyed competences. Until now, this additional information had little effect on the comparability of learning content, because competences are usually described in form of free text. This leaves too much room for interpretation and misunderstandings. Standardized, machine-readable taxonomies are promising alternatives, especially in combination with so-called Competence Frameworks (CFs). In this article, we introduce the Competence Based Learning Model (CBLM). Its development starts with a specific solution for the European e-Competence Framework (e-CF)  and arrives to the creation of a generalized e-CF-independent version. The resulting CBLM is the basis for our two prototypical implementations – an extension for the learning platform Ecosystem Portal (EP) and a plugin for the Learning Management System (LMS) Moodle which extends its CBE-functionality introduced with release v3.1. A short summary and an outlook on future development conclude this article which succeeds our conference paper presented at the IX International GUIDE Conference.

1616-2016 Four hundred years that may reveal more surprises

The Tempest of William Shakespeare deserves special attention. It opens a special view of the Elizabethan age and it can act as a bridge between the magic of the real World and the powers of the human mind. This play has been differently interpreted; however, an original analysis can be developed. An analysis that takes into proper account the possible influence of Italian philosopher Giordano Bruno on the English poet he met just a short while before writing the play.

The impact of perception and presence on emotional reactions. A review of research in virtual reality

ABSTRACT. Virtual reality (VR) has made its way into mainstream psychological research in the last two decades. This technology, with its unique ability to simulate complex, real situations and contexts, offers researchers unprecedented opportunities to investigate human behavior in well controlled designs in the laboratory. One application of VR is the investigation of pathological processes in mental disorders. Research on the processes underlying threat perception, fear, and exposure therapy has shed light on more general aspects of the relation between perception and emotion. Being by its nature virtual, i.e., simulation of reality, VR strongly relies on the adequate selection of specific perceptual cues to activate emotions. Emotional experiences in turn are related to presence, another important concept in VR, which describes the user’s sense of being in a VR environment. We summarizes current research into perception of fear cues, emotion, and presence, aiming at the identification of the most relevant aspects of emotional experience in VR and their mutual relations. A special focus lies on a series of recent experiments designed to test the relative contribution of perception and conceptual information on fear in VR. This strand of research capitalizes on the dissociation between perception (bottom–up input) and conceptual information (top-down input) that is possible in VR. Recent research has highlighted the mutual influence of presence and fear in VR, but has also traced the limits of our current understanding of this relationship. An interoceptive attribution model of presence is suggested as a first step toward an integrative framework for emotion research in VR.

The synergy between manipulative and digital artefacts in a mathematics teaching activity: a co-disciplinary perspective

ABSTRACT. This paper presents a teaching experiment aiming at constructing the meaning of axial symmetry through the mediation of a “duo of artefacts”, made up by a digital artefact and a manipulative one. The meaning of the term “mediation” is described and used from a dual perspective, joining General Didactics and Mathematics Education. Herein, we describe an interactive book, created in a Dynamic Geometry Environment and a teaching sequence, based on the use of such a digital artefact, combined with a manipulative one. The main potential of the interactive book is based on the possibility to drag geometric objects and observe the effects of the dragging. The sequence has been experimented with a 4th grade class and the activities have been videotaped and analysed. Results have been analysed through the cited dual perspective and reveal how the mediation of the duo of artefacts can foster the construction of the mathematical meaning. In this paper we show how the digital artefact, acting in synergy with the manipulative artefact, seems to exploit the potential of the sequence in terms of embodied involvement of the pupils in their cognitive process.

How Virtualization, Decentralization and Network Building Change the Manufacturing Landscape: An Industry 4.0 Perspective

ABSTRACT. The German manufacturing industry has to withstand an increasing global competition on product quality and production costs. As labor costs are high, several industries have suffered severely under the relocation of production facilities towards aspiring countries, which have managed to close the productivity and quality gap substantially. Established manufacturing companies have recognized that customers are not willing to pay large price premiums for incremental quality improvements. As a consequence, many companies from the German manufacturing industry adjust their production focusing on customized products and fast time to market. Leveraging the advantages of novel production strategies such as Agile Manufacturing and Mass Customization, manufacturing companies transform into integrated networks, in which companies unite their core competencies. Hereby, virtualization of the process and supply-chain ensures smooth inter-company operations providing real-time access to relevant product and production information for all participating entities. Boundaries of companies deteriorate, as autonomous systems exchange data, gained by embedded systems throughout the entire value chain. By including Cyber-Physical-Systems, advanced communication between machines is tantamount to their dialogue with humans. The increasing utilization of information and communication technology allows digital engineering of products and production processes alike. Modular simulation and modeling techniques allow decentralized units to flexibly alter products and thereby enable rapid product innovation. The present article describes the developments of Industry 4.0 within the literature and reviews the associated research streams. Hereby, we analyze eight scientific journals with regards to the following research fields: Individualized production, end-to-end engineering in a virtual process chain and production networks. We employ cluster analysis to assign sub-topics into the respective research field. To assess the practical implications, we conducted face-to-face interviews with managers from the industry as well as from the consulting business using a structured interview guideline. The results reveal reasons for the adaption and refusal of Industry 4.0 practices from a managerial point of view. Our findings contribute to the upcoming research stream of Industry 4.0 and support decision makers to assess their need for transformation towards Industry 4.0 practices.

Meeting Industry 4.0 training needs: e-learning sets out the way to move forward

ABSTRACT. Industry 4.0 is an expression that more frequently than others like industry of the future, digital industry, advanced manufacturing and so forth, is used to indicate a series of rapid technological transformations in the design, production and distribution of systems and products. The term, initially referred only to the manufacturing sector, has been progressively extended to the digital revolution which is involving all domains and that is entailing a rapid change of job requirements and skills. As a consequence, new professions are arising but existing jobs are also going through a modification in the skill sets required to perform them. The demands on employees will increase because processes become more complex, interconnected and digital. Currently and in the future, lifelong learning, the ability to think interdisciplinary as well as the development of IT competences will be basic requirements of employees in order to ensure the employability of working people, not only in technology-oriented careers (Richert, Behrens, Jeschke, 2016). Moreover, disruptive changes to business models are producing and will have a profound impact on the employment landscape over the coming years. In such a rapidly evolving employment scenario, the ability to anticipate and prepare for future skills requirements, job content and the aggregate effect on employment is increasingly critical for businesses, governments and individuals in order to fully seize the opportunities presented by these trends (World Economic Forum, The Future of Jobs, 2016). Education has to adapt to the changed conditions and should probably re-think the current model of pedagogy aligning it with the potential of digitization. The use of new didactic methods and the exploitation of multimedia and technological solutions such as virtual laboratories, video-based learning, augmented reality

New teaching paradigms in the new machine age revolution

ABSTRACT. Make students be able to deeply understand topics, to create their own knowledge-creative system, to develop creativity and lateral thinking: those are the target of the education of the future, in the so called New Machine Age. In fact, new skills are demanded by the jobs of the future. According to World Economic Forum, top skills in 2020 will include Creativity, Critical thinking, Emotional intelligence and cognitive Flexibility. How can we build these skills? A possible answer should be the metacognitive approach. Using a metacognitive approach means to teach students how they can find their own strategy, gaining personal control over academic outcomes. It means also, for students, to understand how their mind just works, how they can learn, how they can set the right targets and measure results in a dynamic assessment system. Using a metacognitive approach in distance education means also make students able to follow their own cognitive system, passions and motivation, finding their well-suited learning tools. Any problems or difficulties on learning (even dyslexia or dyscalculia) can be solved without a personalized learning route, just because there are infinite learning paths any student can choose. Any student has her/his own learning system and can find autonomously the right, personalized teaching method. Motivation is the key point of the model. Teacher should motivate students and help learners to understand their own capabilities and how metacognitive system works, also in a distance learning system. This paper analyzes the future new needs in terms of job (soft) skills. Then, following the literature about metacognitive approaches, will delineate a new paradigm of inclusive and self-regulation based teaching for Universities, focused on distance education, advanced tools and new approaches, showing result of an application of these ideas into economics courses.

Modern technologies and distance learning in science didactics

The availability of online video and increasing student access to technology has paved the way for “flipped classroom” models. In such a model, traditional teaching methods are inverted and instruction and lessons are delivered online outside of class moving homework into the classroom. (…) Many instructors have pointed out as well the benefits of a model called “peer instruction” and essentially based on an interactive learning principle, developed by Harvard Professor Eric Mazur in the early 1990s and used in the beginning to improve learning in introductory undergraduate physics classes at Harvard University. (…) In the present article, such modern teaching methods and their possible application to distance learning scientific courses will be discussed, emphasizing how the interplay between the two could allow distance learning teaching to close the gap with respect to traditional didactics, as well as possibly permitting to surpass its limits.

A powerful learning object based on Multiple Answer Test

One of the principal, and still unsolved, problems for the worldwide university system is the high drop-out rate that is observed especially for STEM courses. The causes of this trend are various but many of them are directly related to the sense of abandon felt by students especially during first years. This trend can be inverted providing a set of self-assessment activities to organize students personal study-method and to transmit them a proper self-government. In this context, we realized a self-assessment activity for Physics courses based on Multiple Answers Questionnaire. (…)

A game theory based strategy for reducing energy consumption in cognitive WSN

Wireless sensor networks (WSNs) are one of the most important users of wireless communication technologies in the coming years and some challenges in this area must be addressed for their complete development. Energy consumption and spectrum availability are two of the most severe constraints of WSNs due to their intrinsic nature. The introduction of cognitive capabilities into these networks has arisen to face the issue of spectrum scarcity but could be used to face energy challenges too due to their new range of communication possibilities. In this paper a new strategy based on game theory for cognitive WSNs is discussed. The presented strategy improves energy consumption by taking advantage of the new change-communication-channel capability. Based on game theory, the strategy decides when to change the transmission channel depending on the behavior of the rest of the network nodes. The strategy presented is lightweight but still has higher energy saving rates as compared to noncognitive networks and even to other strategies based on scheduled spectrum sensing. Simulations are presented for several scenarios that demonstrate energy saving rates of around 65% as compared to WSNs without cognitive techniques.

Quality experiences of inquiry in blended contexts: university student approaches to inquiry, technologies, and conceptions of learning

Evaluating the quality of inquiry using technology in blended contexts at university is a complex phenomenon as there are many variables which could account for qualitative variation in the experience. This study looks at reasons for qualitative variation in the university student experience of inquiry using technologies. It considers approaches to inquiry and technologies, conceptions of learning and academic achievement. The results identify which aspects of the experience account for relatively more successful learning and which aspects of the experience tend to be related to less successful experiences. It offers a nuanced understanding of the contribution of technology to successful experiences. The results have implications for the design of activities which involve class and on-line contexts and the way we help students to be successful.

Bridging differing perspectives on technological platforms: toward an integrative framework

An integrative framework is proposed to advance management research on technological platforms, bridging two theoretical perspectives: economics, which sees platforms as double-sided markets, and engineering design, which sees platforms as technological architectures. While the economic perspective informs our understanding of platform competition, the engineering design perspective informs our view of platform innovation. The article argues that platforms can be usefully conceptualized as evolving organizations or meta-organizations that: (1) federate and coordinate constitutive agents who can innovate and compete; (2) create value by generating and harnessing economies of scope in supply or/and in demand; and (3) entail a modular technological architecture composed of a core and a periphery. In support of this conceptualization, a classification system is presented, indicating that technological platforms appear in a variety of organizational forms: within firms, across supply chains, and across industry innovation ecosystems. As an illustration, the framework is then applied to derive a simple model highlighting patterns of interaction between platform innovation and competition, yielding hypotheses that could be tested empirically by future scholars.

Medium of natural phenomena

Looking for the deeper essence of natural phenomena and minimal number of physical laws describing them, a hypothetical vacuum medium is stratified into structural layers, as the levels of observation of respective processes. Instead of a fluidic, the dielectric medium successfully explains all EM phenomena at least. More or less convincingly, inertia and gravitation are explained on EM bases, and the speed of light propagation, with respective reference frame, is conditioned by gravitation itself. The unification of physics is thus initialized, just on the advanced classical bases.

B-learning quality: dimensions, criteria and pedagogical approach

Measuring the quality of a b-learning environment is critical to determine the success of a b-learning course. Several initiatives have been recently conducted on benchmarking and quality in e-learning. Despite these efforts in defining and examining quality issues concerning online courses, a defining instrument to evaluate quality is one of the key challenges for blended learning, since it incorporates both traditional and online instruction methods.

Adapting Grounded Theory in qualitative research: reflections from personal experience

Grounded theory is one of the methodologies that have been widely used in qualitative research. However, researchers, especially inexperienced ones have not been sure about its use in the process of the data collection and analysis. The uncertainty arises mainly from the differences that have emerged between Barney G. Glaser and Anselm L. Strauss who previously pioneered grounded theory together.

Effectiveness of critical thinking instruction in higher education: a systematic review of intervention studies

Promoting students’ critical thinking (CT) has been an essential goal of higher education. However, despite the various attempts to make CT a primary focus of higher education, there is little agreement regarding the conditions under which instruction could result in greater CT outcomes. In this review, we systematically examined current empirical evidence and attempted to explain why some instructional interventions result in greater CT gains than others.

Actual requirements regarding the intellectual capital at an european and international level. The assessment of quality management systems in organisations providing instruction services

The European Union Council had and still has in view the profound changes taking place in society: globalization represents for Europe a competitors intensification in all the economical sectors, while the developing and the diversification of the information technologies can lead to a radical change of the whole learning and educational system, opening the perspectives for learning possibilities and accumulating knowledge during all one´s life.
The topic actuality of this article consist in the fact that, due to the globalization and the international competition intensification, the request for workers with a low qualification level decreases; the new jobs presuppose high performances, flexibility, stress on qualities such as: high level of performance, creativity, openness to change, initiative. People will be obliged to possess much more knowledge, competences and they will have to work in multi spheres teams. Of course not all the people can become conceptual analysts, but an adaptation to the new system, to the new economy is required.
At present, more and more people work in domains in which information is created. In the future this percentage will grow. The use on a large scale of machines and installations will determine that even workers from the basic domains to be better and better prepared. In the countries OECD the unemployment rate is higher for the persons with a second education, unlike the persons with a higher education, the manpower being in this way forced to become more qualified. On the other hand, as more and more work is taking place at an intellectual level, the detaining and manipulating of information becomes an essential quality for each employee. This article has as a main objective the highlighting of actual requirements regarding the quality assurance in instruction services at an European and international level. Thus, the permanent learning strategies from the European Union are presented, which aim at realizing a European space of knowledge. The concept of permanent learning is being analyzed as a new vision in the instruction domain, which is centered on the individual. An important aspect is the developing of basic personal competences and the validation of these through flexible qualification structures.
Due to the complexity of the processes and the context in which they are functioning, the instruction organizations should orient themselves to the models TQM, even though the standard ISO 9001 offers advantages at implementation, connected especially with the processes management, the document control and registrations. The proposed model being a TQM model adapted to the instructional domain and integrated with ISO 9001, can be easily utilized by these organizations.
