Dashboards and OLAP services in LLL and distance learning processes Experiences about log-based learning- and education-management October 25– 29. 2017 HASSACC 2017 Human And Social Sciences at the Common Conference www. hassacc. com

HASSACC 2017, October 25– 29. 2017 Introduction (focused keywords) – A cybernetic education (e-learning) framework needs logs and their real time analyses for system maintenance and personal decisions parallelly. – Log-data will never be used in raw form: dashboards and/or OLAP-services (incl. Data-visualization effects) make the quick understanding of their situation, position, exposure, etc. possible for users (especially to other objects in form of benchmarking results) – Optimized dashboards can not be derived in a standard planning process. User’s behavior patterns (=logs) are necessary to be capable of fine-tuning. – OLAP-services are such a complex phenomena, that quasi each affected person should be educated (=logs) to use it in an efficient way. www. hassacc. com

HASSACC 2017, October 25– 29. 2017 Introduction: out of focus (here and now) – How to optimize data-visualization effects (like Roslinganimations)? – How to optimize models/analyses (like Occam’s razor)? – How to optimize OLAP-services before using by professional users)? – … www. hassacc. com

HASSACC 2017, October 25– 29. 2017 Methods – Similarity analyses for optimizing dashboard services • Checking normativity in the planning • Supporting calculation of the best price/performance ratio – – Without any subjectivity Available as online service (based on C-URL) Automatable Consistence-oriented (with self-checking routines) – OLAP – as standard technique for data handling • Frequently used OLAP-parameter sets lead to dashboards • Using OLAP services need a high level of abstraction capacity by users – Hermeneutics of planned reports should be given in advance – Control views are necessary for avoiding errors – The users should want to see and should be able to accept/tolerate comparisons www. hassacc. com

HASSACC 2017, October 25– 29. 2017 Results – Objective evaluation of dashboards (other arbitrary objects) is possible and it can be executed in an automated way: • Based on similarity analyses • Based on logs • Based on trivial directions of attributes – LLL needs learning materials about OLAP services for developers, maintaining experts, students: • Cybernetic society should be capable of using logs in an efficient way • Persons should tolerate benchmarking at least anonymized • The more efficiently users utilize OLAP services, the more logs will become necessary for crowds www. hassacc. com

HASSACC 2017, October 25– 29. 2017 Discussion – Dashboards are able to support processes, if real decisions will be made – arbitrary constellation stops intuition processes. – The use of OLAP services can become a kind of positive addiction (reports almost always generate new questions). – The misunderstanding of OLAP-reports and/or dashboards is a social risk in the cybernetic society. – Hermeneutics (text-based interpretations) for OLAP reports should be integrated into the services in advance. – Hermeneutics needs consistence control reports too, where a few parallel reports ensure the validity of interpretations. www. hassacc. com
