Positive Computing as Paradigm to Overcome Barriers to Global Co-authoring of Open Educational Resources

2018

The adoption of Open Educational Resources (OER) can support collaboration and knowledge sharing. One of the main areas of the usage OER is the internationalization, i.e., the use in a global context. However, the globally distributed co-creation of digital materials is still low. Therefore, we identify essential barriers, in particular for co-authoring of OER in global environments. We use a design science research method to introduce a barrier framework for co-authoring OER in global settings and propose a wellbeing-based system design constructed from the barrier framework for OER co-authoring tool. We describe how positive computing concepts can be used to overcome barriers, emphasizing…

Crowdsourcing as a mode of open innovation: Exploring drivers of success of a multisided platform through system dynamics modelling

2020

This article aims to explore drivers of success of a crowdsourcing platform. The study conceptualizes crowdsourcing as a mode of open innovation and places such a concept within the context of the sharing economy. Upon this framework, the paper analyses the case of InnoCentive, a successful crowdsourcing platform where innovation-driven organizations search for solutions to their R&D tasks. The system dynamics model frames main InnoCentive business processes and offers a causal perspective on the relationships between platform performance—in terms of users base—and resources structure. The discussion on simulation outputs is carried out through a dynamic performance management view of p…

Ubezpieczenia społeczne doktorantów szkół doktorskich

2020

Th e reform of the doctoral student education system, resulting in a departure from conducting third degree studies in favour of doctoral schools, resulted in changes in the fi eld of social security law. Th e status of a doctoral student receiving a doctoral scholarship has become independent grounds for compulsory retirement, disability and accident insurance. At the same time, it is the basis for voluntary sickness insurance. Th e author criticises the granting of doctoral students the right to acquire cover under this type of insurance. Th eir actual situation when receiving a doctoral scholarship is far diff erent from the situation of other persons (grounds) covered by sickness insura…

Kultūrvēsturisko objektu piesārņojošās sēnes un biodegradācijas risks

2016

Tekstīliju kvalitāti ievērojami samazina tajā esošie mikroorganismi, izraisot degradācijas procesus materiāla šķiedrām. Šī pētījuma mērķis bija atrast sēnes, kuras kontaminējušas dažādus tekstīliju materiālus Latvijas Kara muzejā, un noteikt to ģintis. Pētījuma paraugi tika ievākti no 38 tekstilmateriālu izstrādājumiem, kuri atradās dažādās Kara muzeja telpā. Paraugi tika sēti uz agarizētām iesala ekstrakta barotnēm un uzglabāti istabas temperatūrā 10-12 dienas, lai izveidotos sēņu kolonijas, kuras tiktu pēc tam identificētas pēc morfoloģiskām pazīmēm. No materiālu veidiem, visvairāk sēņu ģintis tika konstatētas kokvilnā, bet no muzeja telpām – pagraba krātuvē. Kopā tika identificētas 11 sē…

Design principles for collaboration platforms for open education

2015

Increasing the current low uptake of Open Education Resources (OER) is a key challenge for researchers and practitioners in the field. User studies have shown that collaboration is a main success factor for successful open educational activities. However, effective collaboration in open educational contexts requires well planned processes and platforms supporting collaboration, in particular in physically distributed settings. We have been investigating the value of such platforms, their main features and user requirements to enable collaboration from immature ideas to completed resources. We used quantitative and qualitative research methods to collect insights from potential users of such…

Shared and personal learning spaces: Challenges for pedagogical design

2012

Abstract The development of new tools for collaboration, such as social software, plays a crucial role in leisure time and work activities. The aim of this article is to summarize the research in the field of computer-supported collaborative learning (CSCL). This is done particularly from the perspective of the blurred line between individual (personal) and group-level (shared) learning that the use of the new tools has forced us to re-think. First, individual and group-level perspectives to learning are discussed to make sense of the major notions of how learning is understood in CSCL research. Second, based on this theoretical grounding, it will be further elaborated what this means to th…

Enhancing the experience of online users of open education

2014

The limited adoption of Open Educational Resources (OER) has kicked off the launch of several projects to search for possible solutions. One of these projects is “Open Educational Ideas and Innovations” (OEI2). The goal of this project is to find alternatives for increasing the uptake of OER and facilitating the collaborative development of OER. To enhance the experience of the users of open education, we interviewed twelve educators and researchers from different higher education institutions across Europe focusing on gathering insights about idea sharing experiences. In this paper, we present our key findings based on these interviews and outline some recommendations for our next open edu…

Fault-proneness of open source software: Exploring its relations to internal software quality and maintenance process

2013

The goal of this study is to explore how fault-proneness of open source software (OSS) could be explained in terms of internal quality attributes and maintenance process metrics. We reviewed earlier studies and performed a multiple case study of eight Java-based projects based on data available in the Source Forge repository. Overall, we studied 342 re- leases of those systems. As is usual, software quality was regarded as a set of internal and external quality attributes. A to- tal of 76 internal quality attributes were measured from the source code of the selected systems via the tool SoftCalc. Two external quality attributes contributing to fault-proneness were in turn obtained from the …

Teaching programming by emphasizing self-direction: How did students react to the active role required of them?

2013

Lecturing is known to be a controversial form of teaching. With massed classrooms, in particular, it tends to constrain the active participation of students. One of the remedies applied to programming education is to use technology that can vitalize interaction in the classroom, while another is to base teaching increasingly on programming activities. In this article, we present the first results of an exploratory study, in which we teach programming without lectures, exams, or grades, by heavily emphasizing programming activity, and, in a pedagogical sense, student self-direction. This article investigates how students reacted to the active role required of them and what issues emerged in …
