A class in a Scientific-Technological Lyceum (age 17) decided to produce a PowerPoint
presentation to introduce nanochemistry and nanotechnology to the students in lower grades.
Because the subject is very new, there was nothing in the School textbooks and, therefore, the
students had to cooperate in order to find materials, to use ICT sources and to take decisions, such
as selecting information and choosing slide layouts. Furthermore, the Cooperative Learning
methodology was employed to solve the problem of setting up the presentation. To make
nanochemistry and nanotechnology a reality for the students, they used a link between these new
frontiers of Chemistry and subjects currently tackled at the Secondary School level. This was the
quantitative determination of Ca
2+
ions by using calcein, a luminescent chemosensor, in which well
known concepts, such as chemical equilibrium and stability constants of coordination compounds,
are involved. The educational aims of the project were to promote both content knowledge and
social skills in Secondary School students. The activity created a good class atmosphere and also
led to the retention of content knowledge.
Keywords: situated learning, cooperative learning, social skills, nanotechnology, quantitative
analysis
Introduction
A booklet of the European Association for Chemical and
Molecular Sciences (EuCheMS 2006) states: “the chemical
and molecular sciences have been fundamental to the current
economic and social achievements in Europe, and will
continue to be the key underpinning sciences for future
European innovation and industrial advances. ” The students,
who will be our future society, must learn for tomorrow’s
world and so they need a meaningful knowledge of the basic
principles of science. The PISA 2003 report (see the web site
http://pisacountry.acer.edu.au/ ) showed that Italian students
do not perform very well in Science; indeed, they have scored
486 (the average score was 500), which made them 27
th
out of
40 countries. Chemistry, like physics and mathematics, is not
very popular among our students. Chemistry, in particular, is
considered too hard to study, abstract and distant from
everyday life. Many students believe they will never have to
do anything with Science and Chemistry, or use them outside
the school. Therefore, it is important that they understand how
the Sciences impact on human life and how it might help in
taking decisions concerning social, technological, and
economic problems. A good strategy might be, in order to
catch the students’ interest and motivate them, to starting with
challenging topics at the cutting edge of science.
In this article we present a teaching-learning activity based
on nanochemistry and nanotechnology. This choice required
both the use of new technologies to carry out the activities and
a non-traditional approach in teaching-learning methodologies
to develop content knowledge and social skills.
The topic is unusual and it is not in the curriculum, so
Information and Communication Technology (ICT) was
indispensable to find and communicate the necessary
information. Knowledge is indispensable but it must now be
combined with a growing number of new skills in
intercultural, computer, linguistic, and ecological fields. In
preparing citizens for the future the role that education plays
is fundamental. Tarozzi (2005), describing the profile of the
ideal graduate of interest to a well-known chemical company,
stresses the following abilities: business direction (strategic
component), implementation (results), networking/team
building, people development, personal leadership
characteristics, communication skills. Content knowledge
alone seems no longer to be sufficient, and social skills are a
must in order to work successfully in a team as our complex
society requires. Schools must keep up with cognitive, socio-
cultural and technological changes. In this society that evolves
so quickly, learning to learn has become a key concept.
Starting from these considerations a complex activity was
decided on to enhance the students’ capacity to face a
complex society. The work involved individual and group
activities, decision making, ICT use, practical work in the
chemistry laboratory, and numerical exercises. The project
was created on the basis of the constructivist theory for
learner driven learning. Both traditional face-to-face
instruction and the cooperative learning approach were used
to carry out the project.
