Mechanics11/Tagebuch

Tuesday 11.09.

 * Introduction: All motion is relative. Experiment 1.0 (Needle-Strip-Exp.). Pupils get copies of Pict. 1.1 (Traces A, B)
 * Homework: Find the velocity.

Regular physics lesson with experiment.

Thursday 13.09.

 * Introduction to wiki editing and WikiEd (Computer room).
 * Homework: Have a look at lesson 1in the wiki.

Pupils show interest. A few have already wiki skills. They like opening an account.

Friday 14.09.

 * Movement with constant velocity (theory).
 * Homework: Study lesson 2 in the wiki. Draw a diagram for the 2 motions.

Tuesday 18.09.

 * Oral exam for 1 pupil. Discussion of homework.
 * Announcement: Digital handouts for presentations required.
 * Homework: “Schneckenpost”

About 60% of the pupils have already accessed the wiki from at home at least once.

Friday 21.09.
(Computer room) Pupils work silently, in their personal speed, solving problems 1.3 and 1.4. Everyone seems occupied and engaged. The first pupil puts a solution (problem 1.4) into the wiki (from own motivation).

One pupil searches a routine to produce mathematical graphs. He uses an extern application. See User:Kiprilo

Tuesday 25.09. to Thursday 04.10.
(4 lessons)

All pupils have got personal welcome messages from Wayne. I did not hear any reactions on this.

We could not use the computer room, as it was always booked. ( For the time being we have only one computer room with about 30 places for a secondary school with 850 pupils!

Several pupils give presentations of solutions to the posed problems. One of them writes his own entry into the wiki, another girl gives me her word documents on CD and I put it into the wiki myself (easy and quick procedure).

Our subject is about calculations and diagrams.

Editing of formula is not easy. How to make a multiplication point? In the meantime I’ve learned about LaTEX and can edit simple formula.

I’ve also found a routine for putting mathematical diagrams to the wiki. For the time being I’m the only one who makes use of it.

Friday 5.10.
Computer room: Introduction to formula editing with LaTEX. Pupils like it! Abilities are very inhomogeneous, but as they work independently with a worksheet, everyone can walk in his own pace.

Monday, at home: I move all our wiki pages to a simpler URL.

9.10.
Group work and solution of problem 1.8, 1.9, 1.10.

11.10.
first written exam: 20 minutes, problem 1.11

46% of all points were reached, average of the two classes.

Survey about the use of Wikieducator.

12.10.
Computer room: experiment 2.1

16.10.
experiment 2.1, definition of acceleration, solution of first exam

18.10.
Theory of constant acceleration, definition.

19.10.
Student edition of the solution of a problem.

Tuesday 10-23
problem 2 .8, problem 2 .4

developing solutions together with students at the blackboard.

The students are grateful, that they get the solution presented.

Thursday 10-25
student presentation: solution to problem 2.2 and 1.10.(Team of two girls). oral exam for one student

Friday 10-26
two oral exams, problem 2.5, 2.7, 2.9

second lesson: attempt to begin a translation of mechanics11 to English, together with the English teacher in the computer room. Was unfortunately not possible because of the failure of computer system.

Instead: developing ideas and sketches for the "science posters for Cambodia" programme. See google groups

the students are creatively engaged.

Autumn holidays

Tuesday 11-6
problem 2.10, students and teacher at blackboard, small steps. The students like the method of tuition.

The students get a copy of four wiki pages on one sheet of paper.

Thursday 11-8
problem 2.6, 2.5, 2.10 the rest

Friday 11-9
computer room: procedure: up loading of the graph of a funktion. The student like the possibility to get creative in a graphical way. Graphs are developed in three steps.
 * 1) Net application matheboard.de for the coordinate system
 * 2) Coordinate system is imported to the drawing programme PAINT, a graph is sketched
 * 3) Up loading to wiki,  placement in user page sandbox

A colleague of mine sends me an e-mail with a copy of his self made and outs for physics classes, ready for use in the wiki

Tuesday, 11-13
Translation to English: Second attempt. Computer room: Together with the English teacher. “Interdisciplinary project”.

Groups of 2-3 students translate Mechanics11 wiki pages from German to English. Students show good interest and internal motivation. Results are being stored on the student user pages. Students use online dictionary Leo.org.

English teacher does not know wikis, is impressed. He remarks that the vocabulary is partly special and difficult for the students.

Talk with the seminar teacher in English from our school. He invites me to present WikiEd to the teacher students in his seminar.
