Background
Doctoral thesis, 2008:
It was interesting you had
to think so much.
Open-ended investigations and
V diagrams in chemistry education
Some of the theoretical background



Meaningful learning, V heuristic (Ausubel,
Novak, Gowin)
Open investigations (Hegarty-Hazel)
Authentic school science (Roth)
Objectives for my doctoral study



contribute to the development of the
laboratory work within education in
chemistry
contribute to research by careful study of
the implementation of open-ended
investigations and a modified version of
Gowin’s V diagram
focus on affective variables of students’
learning; self-concept, beliefs, attitudes
and interest
Methodology and research methods


design-based research
questionnaires, interviews, selfassessment, audio recording in the
class
Implementation



4 open-ended investigations together with V
diagrams in grade-7 in a comprehensive
school in Finland (21 students, 13-14 years
old); their first chemistry course
the problems were chosen by the researcher
together with the teacher; context-based
laboratory groups of 2-5 students
Some results and conclusions



The work with open-ended investigations and
with V diagrams had a favourable effect on the
students self-concept, and on their interest in
chemistry
The group interactions seemed to be important
in the students’ development of their
understanding
A majority of the students felt the V diagrams
had helped them in their understanding of the
lab
The S-team project – our part


cooperation with two chemistry teachers in a secondary
school and one teacher at the teacher education
students in a chemistry class in the secondary school
(16 years old), in a pre-IB class and primary teacher
students have worked with open-ended investigation in
combination with V diagrams
 video-recordings in the classrooms; focus on




teachers introductions
students discussions during their planning and practical work
a presentation of open-ended investigations and of V
diagrams
discussions of different aspects of the work with openended investigations and with V diagrams
