I just had a look on what TED talks there are on learning and education topics. And as always with TED talks I was totally inspired by what I watched. I saw Gever Tulley talking about his tinkering school. This is a school where kids can spent a week surrounded by all kinds of stuff, materials and tools and built whatever they can imagine with it.
This reminded me somehow of what we do with the kids at the scouts. But somehow I think in the last years really building stuff - even when we have our one or two days of building in summer camp - was a bit neglected by us. We - the grown ups - make lists of what we will build and the kids join us. But I guess they would have so much more and possibly greater ideas than we have.
I also noticed recently when I tinkered a present for a friend how much fun it is to actually create something with your hands. We should do that more often. We could offer special tinkering days for the scouts. Or it would be cool to offer such days to school and children in the neighborhood. Or as something they could do in the summer holidays.

Thoughts on the future
Today is one of those Sundays where I just don't know what to do with myself. Everything suddenly feels boring or as if it's too much an effort. But that's not who I want to be. I want to use my time, do something, create something. This won't happen if I just sit around and watch TV.
I want to work on things that change the world, make life a little better. I want to work with people who have real visions, who think big and outside the box. I want to feel alive. I want to have to share something with the world. And once I am doing all those great things I want to be a speaker at a TED conference. Yeah, I guess that would be awesome.
Mmm, this is working. :-) I feel motivation running through my veins already. Hell, there are so many great things to do and learn!!

Mathematische Formeln in HTML
Habe eine nützliche Seite gefunden, die einen Formeln in HTML angeben lässt.
Beschreibende und schließende Statistik: Teil 1A 1.
Ich studiere Bildungswissenschaft an der FernUni Hagen als Teilzeitstudentin. Dieses Semester beschäftige ich mich mit Modul 2A: Empirische Bildungsforchung/Methoden und wiederhole nochmal Modul 2B: Allgemeine Didaktik und Mediendidaktik. Modul 2B widerhole ich, weil ich im letzten Semester nicht wusste, dass man Hausarbeiten anmelden muss. Das war ein wenig ungeschickt.
Ich bin sehr stolz, dass ich dieses Semester schon mit dem Durcharbeiten des Skripts "Beschreibende und schließende Statistik" von Prof. Dr. Willi Wolf begonnen habe.
Hier meine Zusammenfassung für Teil 1A 1:
Merkmalsträger / Objekte / Einheiten = das sind meine Untersuchungsgegenstände, z.B. Schüler
Stichprobe = die Gruppe von Merkmalsträgern, die ich untersuche
M = Merkmal das ich untersuche, z.B. Haarfarbe
N oder n = Stichprobenumfang = Anzahl der Merkmalsträger in meiner Stichprobe
Messwert = Daten, die ich erfasse
xi = Symbol für den Messwert des Objektes i, z.B. x9 = Haarfarbe des 9. Schülers
Urliste = beim ersten erfassen der Daten werden die Meßwerte in der Reihenfolge ihres Auftretens notiert, das wird oft in Zweidimensionalem Rechteckschema gemacht. Die Werte für Objekte 1-10 kommen nebeneinander in die erste Zeile, in die zweite kommen 11-20 usw..
Strichliste = aus der Urliste macht man eine Strichliste: in eine Spalte kommen die Messwerte und in die Spalte daneben wird mit einer Strichliste die Häufigkeit jedes Wertes notiert
Häufigkeitstabelle = aus der Strichliste macht man dann eine Häufigkeitstabelle, d.h. die Striche werden in Zahlen übersetzt.
xi = ACHTUNG: in der Häufigkeitstabelle werden so die möglichen Messwerte bezeichnet
k = Anzahl der möglichen Messwerte
fi = absolute Häufigkeite des möglichen Messwerts xi
hi = relative Häufigkeit hi = fi/N
%hi = prozentuale Häufigkeit %hi = fi/N·100
Datenmatrix / Messwertmatrix = Tabelle, wenn ich mehrere Variablen betrachte. Dann stehen in der linken Spalte die Nummern der Objekte und die anderen Spalten sind jeweils eine Variable
xij = Messwert in der Matrix i=Zeilenindex, j= Spaltenindex, z.B. x10,2 = 2. Messwert in der 10. Zeile
nxm-Matrix = bedeutet Matrix hat n Zeilen/Objekte und m Spalten/Variablen
So, das waren mal die Begriffe aus dem ersten Kapitel. Schon kommen Zweifel auf, ob ich auf diese Art und Weise jemals durch den ganzen Stoff komme. Denn alles zu notieren dauert seine Zeit. Naja, mal sehen. Übungsaufgaben zu dem Kapitel hab ich auch gemacht, war alles ok.
Nur eine Frage hat sich ergeben: Muss ich in der Häufigkeitstabelle auch mögliche Messwerte erfassen, die dann 0-mal aufgetreten sind? Muss da also links der Messwert stehen und rechts 0? Oder kann ich den einfach weglassen?

Critical Thinking: Chapter 1
How I discovered this book
I first came across the book Critical Thining by Richard W. Paul and Linda Elder in the EVTEK library in Finland in 2004. I was doing a semester abroad there. I didn't find the time to really work throught he book then but bought it and now in 2009 it seems like its time has come.
What this book promises to do
The preface is all about how we are what we think and that our thoughts control the way we see our life and how we feel about it. The book is supposed to help me gain control of my thoughts.
Introduction (pages xii - xx)
Good thinking is good in any situation in life and everything we do, want and feel is influenced by our thinking. We do have many bad habits in thinking like making generalizations, looking at things from a fixed point of view or fabricating myths. But if we learn about thinking we can overcome those habits.
Ex I.1 Beginning to think about your thinking
See if you identify any discovery you made about your thinking before you started reading this book.
Mmm. Let me think. :-) I did discover in the past how I can to some extend influence my moods by the way I think. If I'm in a traffic jam and consciously decide not to get angry and annoyed about it that works most of the time. Same with feeling content. If I tell myself that something is ok as it is, a lot of times I can then really feel content with it.
Ex I.2 Understanding the importance of concepts
See if you can think of a time in which you "misused" an imporant concept. Hint: Think of an idea that you commonly use in your thinking, such as friendship, trust, truthfulness, or respect. Have you ever implied you were someone's friend but acted against that person?
Don't know if this is what's meant here, but it happend before that someone told me a secret and I talked about it with my best friend. I do understand the concept of "don't share this with anyone else" but somehow telling my best friend is an exception. The concept of sharing everything with your best friend counts more in that case.
Ex I.3 Beginning to think about your thinking
Consider your thinking in personal relationships, in sports, in dealing with others, as a reader, as a writer, in planning your life... Complete these statements:
1. Right now, I believe my thinking across all domains of my life is of medium quality. I base this judgment on the fact that I do think in stereotypes sometimes and a lot of times I feel like my own thoughts make things worse for me.
2. In the following areas, I think very well:
a. Problem solving and finding creative solutions at work or at the scouts.
b. Planning games and activities with the scouts.
c. When I learn about new things.
3. In the following areas, my thinking is okay, not great, but not terrible either:
a. When I'm writing.
b. In sports.
c. In planning my life.
4. In the following areas, my thinking is probably poor:
a. in personal relationships
b. in relating to the opposite sex
c. in dealing with my emotions
Ex I.4 Changing your habits
Have you ever changed a habit as a result of your conscious effort and planning? What do you have to do to change a habit? Is it easy? If not, why not? What do you think you would have to do to change habits of thought?
I had some success in using the Getting Things Done approach. Collecting everything in one Inbox, writing down all the "To-Dos" I carry in my head.. that worked out fine. I also got quite effective in emptying that inbox and filing stuff. To make this a habit I really have to force myself to keep doing it. Then when I see the benefits it starts to run by itself. Another habit I consciously started is writing ideas down in my idea book. This is so much fun that all I need is to remind myself that the book exists and I use it. The first steps in changing a habit need to be small. If it's too hard to start and takes to much time I find too many excuses not to do it.
Yeah! I made it through the introduction! Now we'll see how I keep up the next days.. :-)

Books on my desk
I have two desks in my room set up in a 90° angle to each other. On one I do my actual work and the other more and more became some sort of extra wide storage room. On it I also keep books about topics I'd like to get deeper into in the future. Or at least some of them. And I think this blog can help me getting started. I'll write here about my progress in reading those books.
And here they are:
- Effective Leadership in Adventure Programming by Simon Priest (Sometime in the future I really want to do the NOLS Outdoor Educator program)
- Lifespan Development by Denise Boyd and Helen Bee (Bought that for one of my classes. Would like to really work it through sometime.)
- The Journey of Adulthood by Barbara R. Bjorklund and Helen Bee (Same as with Lifespan Development)
- Radical Simplicity by Dan Price (The idea of making life more simple seems very appealing.)
- How to make a journal of your life by Dan Price (Ok, I love how Dan Price's books look. And I'd like to make a journal of my life.)
- Cradle to Cradle: Remaking the Way We Make Things by by William McDonough and Michael Braungart (I would like to see this idea spreading. Reminds me of this fantastic website: http://www.storyofstuff.com)
- Wreck this Journal and How to be an explorer of the world by Keri Smith (I just love such unusual creative books.)
- The design of everyday things by Donald Norman (Wonderful book on usability.)
- Critical Thining by Richard W. Paul and Linda Elder (I think I could benefit from working through this book.)
- Worldchanging: A User's Guide for the 21st Century by Alex Steffen (I want to make this world a little better..)
- 20 something manifesto by Christine Hassler (About the 'rough waters of twentysomething years' yeah. I'm still swimming.)
- Change your Luck by Richard Wiseman (Yep, want to change my luck.)
- Your brain: The missing manual by Matthew MacDonald (Very helpful.)
- Various books by Barbara Sher (guaranteed to inspire me and make me feel better)
- Schulfach Glück by Ernst Fritz-Schubert (A book about teaching "Happiness" as a subject in school. I'm very interested in how we could change the school system for the better.)
- Presentation Zen by Garr Reynolds (One day I want to be able to make killer presentations like that.)
- Gelassen und sicher im Stress by Gert Kaluza (A book about stress and how to handle it.)
- Ten Steps to Complex Learning by Jeroen J.G. van Merrienboer and Paul A. Kirschner (Need to write a paper using that method this semester.)
- Mini Max Interventionen by Manfred Prior and Dieter Tangen (I'm quite interested in Coaching and the techniques in here could probably help in all kinds of interactions with people.)
- Getting Things Done by David Allen (Already use part of the system. Want to get better though.)
- A book on Yoga (I love Yoga. Want to start doing it regularly at home.)
Plus, another thing that's on my plate for the next months is the script for my statistics class. Yey!

What do I want with this blog?
Writing my thoughts down helps me think. Even though I know that I don't do it very often. But I think I'd benefit a lot from some regular reflection on my life and by keeping track of the many things I'm working on or am interested in.
Someone who does that in perfection is Sacha Chua. It will be a long way before I manage to write as clear and structured as she does, but if I don't start, I'll never get any better. So here it is: my blog.
