Abstract The past few decades has seen increasing agreement identifying approach and avoidance systems as central concepts in the understanding of human behaviour and personality (Carver, 2005; Carver & Scheier, 2000; Elliot, 1999, 2005). The central focus of this thesis lies in exploring the approach system. The approach system focuses on managing appetitive behaviour and represents a general sensitivity to rewarding stimuli. This system is thought to be accompanied by behavioural tendencies towards such rewarding stimuli and consequently, positive outcomes (e.g., Gable, Reis, & Elliot, 2003). This thesis will examine the approach system as portrayed firstly via the Behavioural Approach System (BAS) as part of one of the most recent and influential personality theories; Gray’s Reinforcement Sensitivity Theory (RST; Gray, 1982; Gray & Mc Naughton, 1996; Pickering & Gray, 1999) and secondly, by means of the social cognitive model of goal orientation (Diefendorff & Mehta, 2007; Dweck, 1996; Elliot & Church, 1997). The two constructs of approach goal orientations which will be chiefly discussed in this thesis are mastery approach orientation and performance approach orientation. The main purpose of this thesis is to investigate these three approach constructs in interaction with situational cues and in the prediction of everyday life outcomes. Work context is an important example of everyday life situation; therefore, this thesis aims to investigate the interaction between the three approach constructs and rewarding climates (situational cues) in the prediction of work outcomes. This thesis therefore contains two parts; the first part will investigate the Behavioural Approach System (BAS) and the second part will investigate performance approach and mastery approach orientations. The first part contains two chapters -two self contained papers- and the second part contains three chapters -three self contained papersix Each paper form it’s own individual chapter. In each chapter, the controversies and ambiguities in theoretical and practical implications involved in the construct will be discussed. In addition, major findings as well as limitations and practical implications will be discussed at the end of each chapter. Following as introduction is a brief review of each chapter.

The teaching project HIS (Holistic International STEMs – Learning with case studies and real life industry experiences) is presented as part of the poster session. Experience shows that German (outgoing) and international (incoming) students have difficulties to communicate properly at the workplace in Germany as well as abroad due to language differences, especially in STEM terms. In addition, young professionals often do not have experience in working in international or virtual teams. All those challenges are current job requirements, not just in global companies. But: How to teach this in higher education? The classical formats of lectures or seminars are not suitable. Therefore, there is a need to develop and prove new teaching formats, within the curriculum as well as extracurricular. With focus on STEM subjects the presented project combines three current impacts on higher education: Internationalization, digitalization, and labor market orientation. The concept of the project is that STEM students from different countries will attend an international, virtual summer school (April to June 2016). They solve real-life job case studies together in small interdisciplinary teams. The participants are mentored by national and international industry partners and STEM professors. With such, the participants will improve language and communication skills, and apply and exchange their expertise as well as gain intercultural work experience. The concept was awarded by the “Stifterverband für die deutsche Wissenschaft” (Donors association for the promotion of humanities and sciences in Germany). The poster introduces the project and exemplary the three-dimensional assignments of one case study (occupational, lingual, and intercultural). At present, the project should be handled as a “project in progress”. Keywords: technology, teaching projects, STEM, internationalization, digitalization, labor market orientation, employability, job orientation, competencies, development of new curricula

From April to June 2016 a new and exclusively virtual teaching format – the international STEM1 Summer School – was provided at the University of Mining and Technology in Freiberg. The paper presents the approach, didactical design, and results of evaluation. The international STEM Summer School was developed and tested within the project „Holistic International STEMs - Learning with case studies and real-life industry experiences“. The aim was to better prepare STEM students for challenges in the current professional world that are characterized by in-ternationalization and digitalization. The project offers some ideas on how to teach the currently re-quired skills and competencies by industry in higher education. The conceptualization of the project was made possible with funding from the Donors\' Association for the Promotion of Humanities and Sciences in Germany2. The exclusively virtual collaboration is due to the different geographical distances and locations of the participating students, which generates specific challenges. On the one hand, technical conditions at the particular places of residence have an impact on virtual collaboration. On the other hand, cultural, lingual, and occupational differences, as well as the differing media literacy, play an important role. In addition, the setting of objectives and provision of incentives is decisive for the shared virtual work. The results of the first round of the international STEM Summer School indicate possible solution strategies based on the three areas of media use, interaction, and task orientation. During the Summer School, students from ten different countries solved real-life job case studies in small interdisciplinary teams. The exchange took place with the help of various e-learning tools like the virtual classroom, wiki, forum and e-portfolio. The participants were mentored by national and international industry partners, STEM professors, and e-tutors. After nine weeks work in intercultural teams they presented their results and learning outcomes during a web conference. The following article focusses on the evaluation results as well as selected insights and challenges.
