• Background
• 1999 reform of Polish educational system
  performed,
• ICT introduced into the core curricula of
  science,
• 1999 2004 - all secondary schools equipped
  with computers - used mostly for learning of
  basic ICT skills,
• no improvement of the quality of science
  education, because
• - lack of good educational software and
  laboratory equipment,
• - low level of teachers competencies at the
  effective use of ICT,
• 2003 , on 5th December - decision of EU Council
  promoting an efficient use of ICT for education.

MPTL11

• Taking these into account we created the
  network of 3 Universities (Poznan, Bialystok
  and Torun) working on enhancing the efficiency
  of teaching with the use of ICT.

MPTL11

• Structure of the Multimedia Mini - Laboratories
  Network
• each university collaborates with the group of 10
  15 science teachers (physics, chemistry and
  biology),
• the effectiveness of methods and tools in
  process of science teaching and learning is quite
  well documented in the literature (for example
  Rogers, Pinto, Pecori, Sassi, Frost, Lavonen,
  Demkanin, Mioduszewska, Ellermeijer, Turlo et
  al.),
• teachers are elaborating the examples of ICT
  methods and tools applied to science teaching and
  learning,
• the results of their work are discussed and
  applied by other teachers within the network.

• Steps of the Projects execution
• Planning of propositions based on literature and
  teachers classroom experience, which reflects
  students misconceptions,
• the assumed educational objectives are the
  mostimportant for selection of the topics,
• financial support was provided by the National
  Ministryof Education,
• schools were equipped with some necessary
  hardware(interfaces, sensors, video cameras,
  etc.) and appropriatesoftware mostly COACH,
  produced by CMA Amsterdam,
• local training courses for teachers were
  organised, the first onewas taking place in
  Poznan (see picture).

Examples of the first teachers project results
from Kujawsko-Pomorskie Region Lets present
some examples of the project results from 2004
I. Physics
1. Physics and astronomy curriculum at the lower
secondary school aided by experiments driven by
Coachlab II and software Coach 5 (by MSc.
Stanislaw Niedbalski). This is a mature
proposition of complete list of MBL school
experiments correlated with the school textbook
edited by New Age (in Polish Nowa Era) and
aimed at increasing the efficiency of teaching
and learning.

2. Studies of magnet falling down in tubes made
from different materials.
MSc. Tadeusz Kubiak showing the experiment
MPTL11

• The MBL investigations of strong magnet falling
  down in plastic, copper and aluminium tubes
  allow
• to study the changes of magnet motion parameters
  (velocity and acceleration) and evaluate the g
  value,
• to compare the motion parameters for magnet
  falling down in the gravitation field (inside a
  plastic tube) with a motion inside diamagnetic
  (copper) and paramagnetic (aluminium) metal
  tubes,
• to verify the induction phenomena (caused by
  induction of electromagnetic force inside a
  metal tubes) and Lenz principle.

3. Studies of relative magnetic permeability of
different substances (by MSc. Mariusz
Kaminski)

Time (min)
In this experiment students can measure the
magnetic induction of different metals and from
the value of ? (factor of magnetic permeability)
to recognise the kind of material (diamagnetic,
ferromagnetic or paramagnetic).
MPTL11

II. Biology and chemistry
4. Investigation of photosynthesis and
respiration of plants (by MSc. Piotr Felski)
This experiment allows to investigate the change
of oxygen and carbon dioxide concentrations as a
function of absorbed light energy for corn
growing in a plastic bottle.
The obtained results allow students to withdrawn
conclusion, that the plants have to respire also
at the night (in darkness).
MPTL11
16
Furthermore, precise analysis of the achieved
data permit to find the relation between O2 and
CO2 concentrations. The plants respire using the
oxygen and dose out CO2 in proportion 11.
5. Monitoring of germination and fermentation
processes (by MSc. Piotr Felski).
The other biological experiments are related to
oxygen process of plants germination and
non-oxygen alcoholic fermentation. In the
first experiment we can observe the results of
germination of pea in darkness during 2 days.
MPTL11
17
Changes of oxygen and CO2 concentrations during
pea germination in darkness.
Thus, germination is the oxygen process, when
oxygen concentration decreases, concentration of
CO2 increases.

6. Investigations of influence of different
medicaments on pH of stomach acid (by MSc.
Agnieszka Dyszczynska). In this experiment
students can verify what are the effects of
different medicaments on different diseases, as
stomach over - acidity or pain.
Changes of pH of cola simulating stomach acid as
a function of time after adding of different
medicaments.

7. Studies of milk fermentation process (by MSc.
Agnieszka Dyszczynska)
Chemical equation describing milk fermentation
C6H12O6 milk bacteries 2 CH3CHOHCOOH

during 10 h of fermentation

pH value and the concentration of oxygen as a
function of time is decreasing for country and
torunian milk faster then for other probes. It
can indicate, that the other samples contain
pseudomilk bacteries instead of real ones.

The Projects rationale

• According to an OECD (2004) survey, the use of
  ICT in education in most countries concentrates
  on sporadic and mechanical information retrieval
  from the Internet.
• Therefore, the main goal of project EU ISE is to
  collect the best practices on the integration of
  ICT into science education, that can also
  motivate students and teachers and improve the
  quality of science teaching and learning.
• These best practices can demonstrate how ICT use
  can make science education more versatile and
  goal-oriented, inspire students active and
  creative self-learning, promote co-operation and
  study in authentic contexts.
• Objectives
• To identify the best practice of using different
  methods and tools of ICT in science education
  across Europe, propose system for benchmarking
  this area,
• designed and test a course for in-service and
  pre-service teacher training in such way.

MPTL11
24

• Target Groups Teachers of science in schools age
  10-18 and trainee teachers of science. Lecturers
  with responsibility for in-service and
  pre-service teachers training
• Main activities
• Identification of the bet practices (based on
  literature and the examples of the effective use
  of ICT in school).
• Creation of a training module for teachers.
• Organisation of the international workshop for
  teacher trainers on EU-ISE.
• The first activity
• International Questionnaire for teachers
  Making the use of ICT in science teaching
  (http//www.fizyka.umk.pl/test/data.php)
• Until now the Polish partner collected
  about 90 answers (60 from women and 30 from men,
  among them more than 50 of physics teachers)
• We got some answer to the questions when,
  for what and in which way the ICT methods and
  tools are used in science education. But we are
  still collecting more data and planing the
  international comparison of the results

MPTL11
25
Further activities

• Creation of the national extended network of
  science teachers and giving information about
  the Project.

Experiments with the use of Ultrasound motion
detector

• inexpensive detector working with continuous,
  coherent wave of 40 kHz frequency, working with
  microcontroler PIC 16C84 and memory EEPROM,

  creation of simulations of school science
  phenomena http//phoenix.sce.fct.unl.pt/modellus/

Additional Polish activity General Polish
competition on Multimedia Aided Science
Experiments

• As the result within three last editions of this
  competition we got more than 110 papers with
  interesting propositions from the field of
  physics, biology, chemistry and environmental
  education.
• Some science teachers propositions have been
  already checked in school practice as the
  ecological refrigerator shown below.

MPTL11
34
Dissemination of the Project results

• Some multimedia aided experiments were presented
  by Krzysztof Sluzewski to school students from
  other european countries.

• The best teacher solutions have been presented
  during the workshops of the Polish Association of
  Science Teachers on How ICT is used in science
  education? organised by us in the year 2005
  (Opole) and 2006 (Warszawa).

• In the next steps we would like to extend our
  Miltimedia Mini - Laboratory network to whole
  Poland!
