Companies still increasingly rely on online training to train employees continuously, effectively, and efficiently. The intention of employees in using e-learning, however, is influenced by various factors. In this study, the influence of external factors on the acceptance of online training was examined in an operational context according to the General Extended Technology Acceptance Model for E-Learning. In this model, computer experience, computer self-efficacy, computer anxiety, perceived enjoyment, and subjective norm were included as important external factors that have been shown to be relevant in numerous empirical studies. In operational contexts, few studies to date have investigated the acceptance model and even less in Europe or Germany. To investigate the influence of external factors, data of 113 employees from a medical institution were collected after participation in an online training course by means of an online questionnaire and were evaluated by regression analyses. The predictors computer experience, perceived enjoyment, and subjective norm were the strongest predictors of perceived usefulness (R2 = 0.59 of the complete model). The perceived ease of use was best explained by the factors computer experience, computer self-efficacy, computer anxiety, and enjoyment (R2 = 0.43 of the complete model). The attitude towards using e-learning and the intention to use e-learning in this study were mainly influenced by perceived usefulness (R2 = 0.67 and R2 = 0.59 of the complete models, together with perceived ease of use). Overall, the acceptance model was largely confirmed in this study.

Illustrations are an essential component of all kinds of learning material. Although there is a long empirical tradition of investigating learning with illustrations, the research has been primarily based on cognitive theories. Two influential theories that continue to advance the literature is the Cognitive Load Theory and the Cognitive Theory of Multimedia Learning. More recently, research has also focussed on motivational, affective and social processes that are triggered or influenced by illustration design and thus can affect learning processes, but studies in this area are limited. In this paper, we introduce an integrative theory of learning with media that builds on the two cognitive theories, discuss how illustrations affect learning by evoking and supporting cognitive, motivational, affective, social and metacognitive processes, report empirical evidence and present examples of how it can be put into practice.
Distance Education | Online Education
Distance/Online learning methods are well established in the areas of continuing and higher education alongside the traditional ways of learning and teaching (e.g., Allen & Seaman, 2016). Although 30 years of ample empirical studies have provided sound theoretical and practical knowledge, we still need more insights on how to deal with the persistent problem of high dropout rates (e.g., Lee & Choi, 2011) and to foster successful student learning (Jo, Park, Yoon, & Sang, 2016). One empirical approach is to explore the extent that learners’ characteristics and skills determine (1) the decision to persist or dropout from an online course and (2) the learning outcomes, and to use critical characteristics as starting points for interventions (Akçapınar et al., 2015; Yukselturk & Bulut, 2007). Although these approaches often start with diagnostics of learner characteristics before learning (e.g., Yukselturk & Bulut, 2007), diagnostic methods applied while learning have become popular (Kinnebrew et al., 2013; Lile, 2011). Modern approaches use data mining and learning analytics to identify learners that have problems. These methods attempt to benefit from objective data that are provided by various types of log systems that record online traces (Akçapınar, 2015). Data mining methods might result in better online diagnostics and intervention methods when the mechanisms that underlie usage patterns are known. Hence, relating usage patterns to student characteristics has been recommended to render them meaningful (Akçapınar, 2015).
Game-Based Learning & Educational Games
Game-based learning means using games in educational contexts to reach educational objectives (Connolly et al., 2012). These games could be entertaining games or educational games. While entertaining games are mainly designed for fun, entertainment, and recreation, educational games are a subgroup of games that are designed for educational purposes (Connolly et al., 2012). The main goal of game-based learning is learning and behavioral change (Connolly et al., 2012). Game-based learning is often used in the same context as serious games (Boyle et al., 2016), but serious games are often comprehended in a broader sense. Djaouti et al. (2011, p. 120), for example, defined serious games as “any piece of software that merges a non-entertaining purpose (serious) with a video game structure (game).” This definition includes also purposes that have both non-entertaining and non-educational purposes. More often, the broader purposes of serious games are scratched by naming (1) markets like government and non-governmental organization, defense, healthcare, marketing and communication, corporate, industry and education, and (2) purposes like games for health, advergames, games for training, games for education, games for science and research, production, and games as work (Sawyer and Smith, 2008).
I am primarily interested in educational games and their motivational, affective, and cognitive outcomes when playing/learning with them, as well as learner characteristics that influence the success of gameplay and learning.
