What do we want to know?

• Direction of the primary particle

• Energy of the primary particle

A lot of DATA

19 july 2005 CROP workshop Lincoln Nebraska

First results! in Nijmegen

Publication in “Nederlands Tijdschrift voor Natuurkunde ” december 2004

by Charles Timmermans et al.

Highest energy particle ever observed in the Netherlands!

Implementation of The Project

– Structure of Education in The Netherlands – Plans to implement HiSPARC in Education

• Knowledge of science:• Curriculum• Practical Assigments • Master Piece: the happy few?

– The Future ?

19 july 2005 CROP workshop Lincoln Nebraska

Education in The Netherlands

Some general remarks• The governement is responsible• Compulsory school attendance• Public-authority and Private Schools

19 july 2005 CROP workshop Lincoln Nebraska

HiSPARC

19 july 2005 CROP workshop Lincoln Nebraska

The Second Phase = Higher Secondary

• More subjects• Self-study• Independence of the student• The teacher as Coach• Master Piece

The First Phase = Lower Secondary

19 july 2005 CROP workshop Lincoln Nebraska

Profiles

Program The Second Phase (age 15, 16, 17)

• partly a general curriculum

• partly 1 out of 4 profiles:– Society and Culture– Society and Economy– Nature and Health– Nature and Technology

19 july 2005 CROP workshop Lincoln Nebraska

Science subjectsThe First Phase: Age 12, 13, 14:

– Physics/Chemistry, Biology: all students

The Second Phase Age 15,16,17

– Physics compulsory for Nature and Technology

– Physics optional for Nature and Health – Knowledge of Science: all students – Master Piece

In 2007: new science course????

19 july 2005 CROP workshop Lincoln Nebraska

HiSPARC = Master Piece?

• Construction? Yes• Maintenance an Calibration? Yes• And Then???• Practical Assignments <> research ???• All students ???

New Plan?Let`s review the possibilities

HiSPARC Symposia

19 july 2005 CROP workshop Lincoln Nebraska

Junior High School

Project• For all student• In cooperation with Math, Biology and

Geography• New didactics• And the Spark Chamber

19 july 2005 CROP workshop Lincoln Nebraska

Position of the Spark Chamber

• To trigger the interest in cosmic rays

• To make the step from subatomair world to daily life

19 july 2005 CROP workshop Lincoln Nebraska

Senior High Schoolall students

Knowledge of science– Approach…Astronomy– Approach…Radiation– Public website (KennisLink)

19 july 2005 CROP workshop Lincoln Nebraska

Senior High School (suite)

all students

Didactics• Normal course• E-learning course

19 july 2005 CROP workshop Lincoln Nebraska

The use of Electronic Learning Environment

• Problem of the new students: The detector is a black box for them

• Students in 5 clusters• Virtual teaching AND individual coaching

Pratical Assignments

• To what particles is the detector sensible?

• The influence of shielding

• Atmospheric Effects

• The number of muons that hits the body each second

• Variation with Detector Positions and Angles

19 july 2005 CROP workshop Lincoln Nebraska

• Influence of the treshold and the voltage of the PMT

• Angulair distribution of the cosmic rays

Senior High SchoolMaster Piece

Students will not be visitors to the scientific institutions, they will be there as

collaborators

19 july 2005 CROP workshop Lincoln Nebraska

The Future?

• Communication environment• Expanding and enhancing the network• National Symposium• Workshops and Lectures at schools• LOFAR• HiPARC reviews• Workshop for teachers• European collaboration
