2ND SCIENTIX CONFERENCE
Background
ROSE
PISA
EuropeanComission
ScienceEducation
in Portugal
The teaching has (in
particular in the more
wealthy countries) to be
motivating, meaningful
and engaging.Sjøberg & Schreiner (2010)
Students need to be able
to find the information that
they want, critically
evaluate its reliability and
relevance, and integrate
and apply this information
to solve their information
needs.OECD (2010)
Low interest about
science in
developed countries
In international
exams, the
portuguese
students’ perform in
science is lower,
comparing with
other countries.
Facts Implications
In most of European
countries, science
teaching
methods are
essentially
deductive.A reversal of school
science-teaching
pedagogy from mainly
deductive to inquiry-
based methods provides
the means to increase
interest in science. EC (2007)
Students are choosing
less scientific and
technology courses in
higher education.
The more efficient way to raise
curiosity about science, in children
and young people, is providing
them experimental activities at the
earliest age.Fiolhais (2011)
Schools’ location
Objective
To disseminate
a teaching
experience
between 3
classes in 3
different
schools,
located in th
north of
Portugal.

Common denominators between the lessons
7th grade
students
ICT itself can and will not replace
hands-on activities, scientifically driven
experiments, vivid discussions about
explanations and many other actions(Welzel-Breuer et al., 2010)
PBL can be defined as an inquiry process that resolves questions,
curiosities, doubts, and uncertainties about complex phenomena in life
(Barell, 2007)

Total (average)
Conclusions- Most of the students (about 80% total average) enjoyed all part of the lessons and think they learned all that was discussed during the lessons;
- The favorite part of the lesson to students is to “manipulate objects” (i. e., doing experiments and using the software – 40% to 50%), only 10% say “to solve the problem question”;
- The teacher still holds a key role in students’ perception about learning: > 90% (total average) indicates that teacher facilitated their task;
- The majority of pupils understood all of the lesson;
- 60-70 % of students considered the work done as suitable (nor too difficult or too easy);
- Most students (70%) stated that their peers helped them in the task
- The major difficulties experienced by pupils were related to list questions (25-40%) and to solve the problem (20-30%)
- The most positive aspects varied among the different themes: - To learn new things – volcanic activity (21%)- To use the software - seismology (38%)- To do the experiment – volcanic activity (50%)- To discuss the problem – Moon craters (17%)
Conclusions
What 21st Century Skills were developed?
Collaboration → Group work
Knowledge construction → Students’ Research
Self-regulation → Peers and teacher feedback and self-evaluation
Real-world problem-solving and innovation → Problem Based Learning
The use of ICT for learning → Software (Salsa J, Erupt3, Make-a-Quake…)
Skilled communication → Final product presented to the class
Implications
- The lessons had a significant impact on students and the use of software and making
the experiment was relevant, as well as the collaborative working;
- With this study, performed with a reduced sample, it was not our purpose to
accomplish result generalization, but to reflect about the strengths and weaknesses of
PBL’s application, using the same educational strategies, in science learning in 7th
grade students;
- It would be necessary to develop further investigation with this kind of educational
methodology, to a greater variety of themes, with a student larger sample, that would
allow to study its effects in students’ learning in a long term.
