Efficient R Programming – Book recommendation

Mai 16, 2017 - 18:56

The book "Efficient R Programming: A Practical Guide to Smarter Programming" by Colin Gillespie & Robing Lovelace is a collection of very important resources. It is not only helpful for the advanced data scientist but also the intermediate and even R beginner can benefit a great deal from the book. It covers important R related everyday subjects and activities. Each self-contained chapter starts with 5 top five tips and discusses practical issues. The book is rich in internet references, which I have collected and presented in 10 link lists, divided by the book chapters. Weiterlesen ...

R – most minimal learning resources

Mai 16, 2017 - 18:07

With December last year, I started to learn data science using R. As a self-determined learner, I had not only to find resources, that are adequate to my learning goals and status of competencies but also to plan and organize my spare time for my self-organized continuing education.This article reports about my strange learning behavior and closes with 3 tips on R learning resources for the beginner, suggesting the most minimal learning set for the prospective data scientist.

Hands-On Programming with R – Book recommendation

Mai 16, 2017 - 16:09

"Hands-On Programming with R" by Garrett Grolemund is a very gentle introduction to programming with R. It starts with explaining the installation and the R user interface and covers step by step more advances topics. It is is not a programming book per se, as you will learn how to use R for data science. If you want to learn R from scratch and you are a newcomer to programming, then this is the book I would like warmly to recommend! Weiterlesen ...

Twitter word clouds explained

April 9, 2017 - 11:38

Yesterday I have experimented with R packages for generating Twitter Word clouds. In this post, I will give some hints how to proceed. I will also refer to my GitHub repository, where you can find the complete program code. I have added some examples in generating all the twitter clouds for all member of the IBM staff with a Twitter account, for the department and the university account. Weiterlesen ...

IMB Twitter Wordclouds

April 8, 2017 - 19:26

Der Beitrag stellt Wordclouds vor, die sich aus den Twitter-Accounts der Mitarbeiter/innen am IMB ergeben. Ich habe das nicht nur aus Spielerei gemacht, sondern weil ein Studierender aus unserem Lehrgang Personalmanagement und Kompetenzentwicklung mit Neuen Medien die Nutzung von Social Media bei Personalentwicklungsfirmen als Masterthese untersuchen möchte. – Das Bild zeigt meine eigene Twitter-Wordcloud.

How to support self-determined learners? (Part 2)

März 15, 2017 - 13:11

In the first episode about my personal learning experiences, I criticized that rigid curricula are not adequate to support experienced learner. This second episode is a follow up of this thought. I discuss the subject in more detail and in a more general way addressing not only R programming and data science but generally all adult learners who have work experiences and want to improve their knowledge and skills in their respective field of expertise. I will also present a model how self-determined learners could better be supported. Weiterlesen ...

Reports from an adventurous learning journey (Part 1)

März 13, 2017 - 23:49

This is the first report of a series of personal experiences in learning the statistical programming language R to acquire competencies of a data scientist. In this kick-off article, I will present an example, why cohort learning in the age of individualisation is not appropriate anymore. I will suggest an alternative, present my earned certificates and explain why I interrupted (or aborted?) a nine-course introduction to data science taught by professors of John Hopkins University and offered via the MOOC-platform Coursera.

Bildung für eine joblose Gesellschaft

März 13, 2017 - 17:03

Der Artikel wirft die Frage auf, welche Veränderungen im Bildungsbereich durch die zu aktuelle technologische Entwicklung zu erwarten sind. Im Rahmen einer Videoaufzeichnung eines Vortrags an der Hamburger Universität vertrete ich die Auffassung, dass die kommende Rationalisierungswelle nicht mehr durch höhere (Aus-)Bildung ausreichend entgegen gewirkt werden kann und dass hohe Raten von Arbeitslosigkeit (ca. 50%) demnächst zu erwarten sind. Welche Bildung brauchen wir für eine Gesellschaft, wo es nicht mehr in erster Linie mehr darum geht, sich für einen Arbeitsplatz zu qualifizieren? Weiterlesen ...

eEducation Werkzeuge und Methoden

März 13, 2017 - 07:19

Der Beitrag gibt eine Aufstellung über die am IMB verwendeten Server-Installationen, die insbesondere für den Masterlehrgang eEducation als Toolbox dienen. Studierenden sollen in unseren Lehrgängen sowohl ein kritisch-reflektiertes Verständnis zu modernen Bildungssettings entwickeln, als auch befähigt werden, bildungstechologische Lernarrangement selbst zu gestalten, zu entwickeln und zu implementieren. Ein eigener Abschnitt stellt eine Checkliste für Fragen zur Unterstützung bei auftauchenden Problemen zusammen. Weiterlesen ...
