CHAPTER ONE
THE PROBLEM
1.1 Introduction
For over five decades, a number of efforts have been made nationally and
internationally to improve the teaching and learning of science in schools. This has been
a subject of considerable concern in Nigeria. The central concern has been to make the
teaching and learning of science in the classroom more meaningful and more effective in
order to achieve the educational goals of the society.
Effective science teaching involves student’s active participation in the teachinglearning
process, mo re especially as it involves asking and answering questions. Lack of
active participation of students has been described as one of the factors responsible for
poor academic performances in science subjects (Inyang, 1988, Bichi; 1988, Mari, 1994
and Usman, 2001). It has also been indicated in WAEC chief examiners report (2004)
results of secondary schools where students performances are generally poor in Biology,
Chemistry, Physics and other science related subjects. They perform poorly in questions
that require high-level cognitive domain (Winne, 2007). The reason why students
perform poorly in questions at high level cognitive domain could be that teachers
frequently ask questions that are low in cognitive domain. Therefore the aim of
enhancing student’s academic achievement will not be realized if questions asked by
teachers are not in conformity with demands of all the levels of Bloom’s taxonomy of
educational objectives (cognitive domain).
Integrated science was introduced as a foundation to the science courses as well
as to promote scientific literacy amongst the Nigeria youths; this is introduced at the
lower level of education. It is supposed to give the students the basic scientific
knowledge they need as well as to equip them to be scientifically literate. This is because
most of the students terminate their science learning at the junior secondary school level.
Integrated science as defined by Olanrewaju (1983) is an approach to science in
which concepts and principles are presented so as to express the functional unity of
scientific thought. The aim of integrated science programme as stated by Usman (2001)
is to enable students achieve the process and product content of integrated science. The
National Policy on Education (FME, 2004) include integrated science as a core subject at
2
the junior secondary school level in its curriculum. Integrated science emphasizes the
teaching and learning processes which lead to fundamental foundation in the sciences at
all levels of education.
Low academic achievement of students in the sciences, integrated science
inclusive, has been a growing concern in the school. To this effect, scholars have carried
out studies to investigate the factors that may be responsible. Some of these factors have
been linked to the non-availability of teaching materials, lack of adequate laboratory and
it facilities, and the methods of teaching used by the teachers among others (Usman, 2007
and 2008).
For students to achieve high in science, the teacher has to use a strategy which
will enable the students to understand science concepts and create conducive
environment that will change effective teacher-student interaction. The teacher must
know the extent to which students have knowledge of a learning task. This is a
prerequisite for effective teaching (Bloom, 1981, Hargreaves, 1984).The student
unfortunately is not a transparent box through which the teacher can see and read the
amount of knowledge that has been or is being acquired. The teacher should be able to
assess the student’s understanding of science concept through questioning based on his
experiences in teaching/learning outcome in accordance with Bloom’s taxonomy of
cognitive domain. The age-old technique made famous by Socrates and practiced by
classroom teachers has been the use of questions to aid students in developing ideas and
conclusions and drawing their own inferences. Therefore a question is a direction to a
learner to examine instructional materials or his memory of it and to produce some
response (Redfield and Rouseau, 1981, Gandu, 2006).
The cognitive level of a question refers to the nature of cognitive processes
required to answer it. There are two broad types of cognitive question styles which are
the low-level and high level cognitive questions styles. Low-level questions are called
knowledge questions that require students to recall material easily from what they are
taught (Cotton, 2001). According to her, low-level questions help students to remember
factual information, study for test previously read or presented by a teacher. They are
designed to solicit from students’ concept, information, feeling or experiences that were
gained in the past and stored in the memory. They also include questions that can be
3
answered with yes or no, a single word or a short phrase. Sample key words are;
complete, define, count, identify, list, name, recall, recite, observe, what, when, where
among others. Low-level cognitive questions according to (Callahan and Clark, 1988;
Gandu 2006) do not challenge the students’ ability to think, but only to remember. They
are used to reinforce learning and to check on students’ retention of what is learnt.
High-level cognitive questions are those requiring students to mentally
manipulate information they have learned and to answer with reasoned evidence (Brualdi,
1998). They are also called open-ended, interpretative, evaluative, inquiry, inferential and
synthesis questions that require skills. By using these skills, students do not remember
only factual knowledge, instead they use their knowledge to solve a problem, to think
intuitively, creatively, hypothetically, to analyze, to use their imagination, to expose a
value system, to make judgment and to evaluate (Derfel, 2002). According to him, it is
believed that high-level cognitive question style reveals whether or not a student has
grasped a concept taught. This is because a student needs to have a deep understanding of
the topic in order to answer this type of question, that is high-level cognitive question.
Sample key words, for high-level cognitive questions are: apply a principle, predict,
manipulate, generalize, hypothesize, judge, evaluate.
Various authors Brualdi, (1998) Cotton, (2001) Susan, (2001) have described the
impact of cognitive question styles on academic achievement of students as it developed
interest and motivate students to become actively involved in lessons. It also helps in
assessing students achievement of instructional goals and objectives. Arends (1994)
argues that many of the findings concerning the effects of using low-level cognitive
versus high-level cognitive questions have been inconclusive at secondary school level.
While some studies and popular belief favor asking high-level cognitive question, other
studies reveal the positive effect of asking low-level cognitive questions (Brualdi, 1998,
Gandu, 2006). Therefore based on the findings of the studies above using low-level and
high-level cognitive questioning styles, there is the need to investigate the effect of
teachers cognitive question styles on academic achievement of students in integrated
science.
In Nigeria and many other countries, women are grossly under-represented in
scientific and technological fields. Science educators have carried out a number of studies
