The
task of teaching
3.
Directing
learning activities
In the previous section, we insisted a lot on how the teacher has to
bear the students in mind when designing and constructing the curriculum, but
in this function he/she does not interact directly with them. It is when the
activities are actually carried out that teacher / student interaction is to
the fore and that the teacher's influence is decisive in the learning
process.
It is clear that the teacher's role during learning activities depends
on the teaching and learning model adopted, on the subject-matter and on the
type of activity. We have already explained our preference for a holistic
teaching model and it is also clear that we are interested in technical
education -- but what is our learning model? What kind of activities are we
thinking of?
3.1.
The
learning model
In the previous chapter we saw that research into the teaching of
technology is very poor. However, the models used in science teaching and the
projects set up on the basis of this research are governed by a dominant
general theoretical framework. This is based on Piagetian constructivism and
Vygotskian socio-cultural psychology. In our view, this theoretical framework
is completely acceptable for technical education and we want to highlight four
aspects of it that are especially significant for this education:
- The student has his/her own knowledge and cognitive competences.
- For the child, new knowledge appears first at the social level and is
later internalized.
- The acquisition of knowledge is understood as a creation of
meanings.
- The creation of meanings requires active and voluntary involvement
from the student.
Without questioning the internalization of knowledge, this theoretical
framework highlights social intervention in the learning process and thereby
emphasizes the importance of students relationships with their teacher, with
classmates and with their socio-cultural environment.
3.2.
Kinds
of activities
First, we should note that the concept of activity is extremely broad.
It may refer to a didactic unit programmed over several days, to the various
parts of a didactic unit, or to the tasks students carry out at any given
moment. We will use the same word for all these meanings, and we are sure that
the context will make the sense clear in each case.
Several criteria exist for distinguishing kinds of activities. For
example, if we look at their function in the narrative thread, we can speak of
activities of introduction, of synthesis, of reinforcement etc. But we are
interested only in criteria that are useful for characterizing activities for
teaching technology to children. For that reason we will focus our attention on
well-known experiences in technological education and childrens
education.
In the previous chapter, we commented that technologists use three
methodologies which have also become didactic methods for teaching technology
in secondary education: the analysis of objects, the project method and the use
of case studies.
We have no references to experiences of using case studies with
children. It seems that experiments with activities based on this method are
needed.
However, the analysis of objects and the project method can be the basis
for many activities in technical education for children, as we do have prior
experiences that justify these methodologies.
The analysis of objects is a kind of activity very close to traditional
observation and exploration activities. It has been widely used in nursery and
primary classrooms and is similar to the Research on technique that is used in primary education in the Netherlands
(see previous chapter). It is an activity that stems from concrete objects and
places emphasis on the function, composition and structure of objects and the
way they work. This kind of activity encourages students to look at things
analytically: parts of a general system are separated from each other and then
put together again in new systems.
The project method has important antecedents in the history of
education, since it is based on the pedagogic method of Dewey (1938), which has
its basis in what is known as the scientific method". Dewey
distinguished five stages:
1) recognition of the existence of a real or
significant problem that creates a need or doubt in the students,
2) definition or delimitation of the doubt or
problem,
3) formulation of possible solutions,
4) complete analysis of the future
consequences of each solution and selection of an option,
5) testing out the hypothesis or the selected plan of
action.
As can be seen, the above is very similar to the project method which we
explained in the previous chapter.
There are also several parallels between the project
method and the method of teaching sciences called problem solving that has been used in many primary schools. It is
only necessary to look at the diagram in Fig. 2 to see the many similarities
between the two methods (extracted from Johnsey, R., 1986).
A further methodological approach linked to the projects method is the discovery method. This is an approach to
science teaching based on pure constructivism, which has been criticized
because of the excessive isolation of students and for ignoring the social
aspect of learning.
With these precedents, it does not seem rash to see the projects method
as the kind of activity most appropriate for technical education. In fact, it
is very similar to the Making technique
used in the Netherlands (see previous chapter). Moreover, this method, like the
analysis of objects, also fits perfectly with the pedagogic principles of
activity, of autonomy and of the play-work duality that are strongly rooted in
nursery and primary schools.
Turning now to young childrens education, we also find important
scientific and technical experiences. Some examples are the physical knowledge activities of Kamii
and DeVries (1978), of a clear Piagetian orientation and with the aim of
facilitating development through action; or the activities in scientific
education developed by Arcà, Guidoni and Mazzoli (1990) with their strong
socio-cultural perspective on learning; or those based on experiments carried out
by Lück (2000).
As these experiences, along with many others, have been found to be
valuable for the scientific education of young children, they can provide us
with guidelines for working out suitable technical education activities.
Lastly, we want to refer to another kind of activity that is based, on
the one hand, on the view of learning as the development of the capacity to
explain and act and, on the other, on the analogy that Ogborn (1996) set up
between scientific explanation and the narration of a story, in which the
protagonists are the concepts and laws of science.
Tales are a traditional way of teaching children. What we propose as an
activity is the scientific or
technological tale, i.e. to use the narrative rules of tales for talking
about scientific or technological topics. Why must tales always present social
or moral stories of bear cubs and rabbits? Why shouldnt they deal with
coloured lights that collide with glass and change colour when they pass
through it, or that collide with mirrors and are thrown back? And we also have
the advantage that these stories can be illustrated through real experiments.
These kinds of activities, and the teaching and learning framework
assumed, imply that teachers should have a large fund of interesting situations
to be worked on in class. They also need technical and reasoning skills, and
considerable talent in relating to and communicating with students.
3.3.
The
teacher's role in the classroom
When we discussed curricular design, we dealt with the importance of
teachers cultural and psychological-pedagogical skills. We will not dwell on
these any further, although it is clear that these skills are also important in
the teacher's task of directing learning activities.
The skills that we discuss in this section are those related to direct
contact with students and that correspond to several functions of the teacher
in class. Although most of these teacher functions -- management,
communication, diagnosis etc. -- are not specific to technical education, we
will bear this context in mind when discussing them.
The following focuses on teachers and, though we will often use
expressions such as the teacher decides", it should not be thought that
the sole voice and will in the class-room is the teachers. What we mean is
that the teacher has the ultimate responsibility for decisions taken in class,
but that she/he often decides to do what the student proposes.
First, the teacher is an authority in the class and is responsible for
managing all the learning and social interaction processes:
Social management. - A
class is a micro-world with a social organization, in which the teacher
represents the world of adults. He/she is the source of knowledge and is
responsible for good social functioning, which are all facts recognized by the
students. Social management implies both making sure that the rules of
behaviour are respected, and looking after students autonomy. In addition, it
implies organizing work in teams and encouraging the participation of
everyone.
Management of the learning process. - The teacher is responsible for choosing the activities that have to
be carried out, either for the class as a whole or for individual students. In
order to ensure educational progress, he/she tells them when to start and when
to finish, what we do now and what later. At a more concrete level, he/she also
has to decide what values, experiences, concepts and new ideas need to be
introduced, what has to be remembered, which proposals must be accepted, which
have to be rejected, etc. We want particularly to highlight the management of
the specific language that has to be introduced into technical education
activities.
During the last decade interesting research has been done into the
performance of science teachers in the class-room. This research has emphasized
the communicative value of the various languages (verbal, body, visual, actions
etc.) that are used to construct meanings and the teacher-student relationship.
From this point of view, we want to distinguish the following functions of the
teacher:
Motivating. - For
many educational specialists, this is the first and most important function of
the teacher in the class-room. We have already said that often students' and
teachers interests do not coincide, but there are certain contents that the
child must learn. The teacher has to be careful to create and to maintain the
student's interest so as to ensure that he/she learns these contents properly.
In the case of technical education, the teacher has to pay particular attention
to motivating girls and to be very sensitive to their reactions, since, in
general, the social environment does not favour equality between girls and boys
in this area.
Rhetorical skills. - That is
to say, teachers must understand their "audience" and have sufficient
empathy to understand feedback from students. They must be able to adapt their
performance (verbal, gestures, visual, actions etc.) to the ZPD of students.
However, teachers should also be able to modify their performance according to
the feedback received and should have the resources to diversify their
arguments. Professional skills would probably improve if rhetoric and reasoning
components were introduced into teacher training.
Seeker after knowledge. -
The teacher must get students to communicate their knowledge and explain the
reasons for their actions. We should not forget that making students knowledge
explicit improves learning significantly.
Responsible for maintaining the narrative. - We have already spoken of this function when
discussing the sequence of contents: the teacher has to try to help students
understand what they are doing, why they are doing it, what they will do next
and how they will carry on their technological activity. He/she has to offer
summaries of what has been done and to try to relate the various activities to
each other.
Manager of the communicative approach. - The teacher has to be aware of and to manage, in a way that suits
his/her educational purposes, the kind of communication that is set up between
him/her and the class. In his/her task of planning communication, the work of
Scott and Mortimer (2002) is relevant. These researchers posed four possible
communicative approaches based on two dimensions: interactivity (an approach is
interactive if it allows the participation of others) and dialogic character
(an approach is dialogic if it accepts more than one opinion or point of view).
The dialogic and non-authoritative approach is good, but it is not always the
best. At this point we want to insist once again on the importance of
childrens gender, because in teaching science and technology topics the
teacher must take care not to prejudge, and to overcome possible communication
barriers caused by social and/or cultural factors.
Observer. - There
are also moments when the teacher is an observer picking up information. In
fact, the teacher must always adopt an observant attitude, but he/she has to
foresee moments that are particularly apt for the collection of
information.
For this reason, it is important to prepare charts for systematic
observation of students activity and to plan several kinds of observation,
depending on the purpose of the data collected. The teacher may sometimes
collect data in order to illustrate a presentation of the activity to their
colleagues, but usually the collection of data serves a diagnostic or
evaluative purpose.
