Experiments play an essential role in science research
and also in science education. The first experiments were part of science
teaching/learning at universities already at the beginning of the nineteenth
century. The effectiveness of science education through students engaging in
practical activities was preferred by some but doubted by others. The
contemporary constructivist approach in science education promotes students’
experimentation because students have a greater share in activity and inquiry.
Not only are student experiments important for teaching/learning science, but
also demonstration experiments play an important role as well. The goal of our
design-based research is to answer the question: Does the demonstration
experiment have a place in today's constructivist science teaching/learning?
What innovations are appropriate for the implementation of demonstration
experiments in today’s constructivist science teaching/learning? As a result of
our design-based research we found several principles for the effective
implementation of demonstration experiments in teaching/learning science: an
emphasis on the objective of demonstration experiments, controlled observation
of demonstration experiments, and development of students´ thinking and
creativity in demonstration experiments. The appropriate implementation of
these demonstration experiments in science education can lead to a better
understanding of the nature of experiments, as well as to a better
understanding of science concepts, phenomena, science processes and science
laws and to increasing the required educational objectives. The next student
gain is acquaintance with the experimental skills needed for their own
meaningful experimentation under the guidance of a teacher. These skills
include the ability to observe consistently and accurately, to use the
apparatus correctly, to measure, to create and to test hypotheses of observed
phenomena, to analyse results of experiments and to draw conclusions.
