Abstract
This thesis presents results of a secondary analysis of South African Grade 8
learners' responses to the TIMSS 1999 Population 2 Science questions, and the
results of a test and group interviews with learners from three high schools in
Pietermaritzburg. The study is motivated by the need to understand the reasons for
the poor performance of SA Grade 8 natural science learners in the TIMSS 1999
study. The aim of the study was to identify possible misconceptions held and errors
made by SA science learners and to pinpoint pos sible causes and sources of these
misconceptions and errors. An analysis of the SA learners' responses contained in
the TIMSS 1999 Population 2 data and the test results from the Pietermaritzburg
schools was used to identify possible misconceptions held and errors made by SA
learners on certain science topics. The questions used in the Pietermaritzburg study
were selected from the TIMSS 1999 population 2 science quest ions. The questions
were selected based on perceived minimal levels of guessing by learners when
answering these questions in the TIMSS 1999 study. The three schools selected for
inclusion in this study in Pietermaritzburg were chosen based on their former
classification as Indian, Coloured and Black schools. The majority of pupils at each
of these three schools still reflect this racial composition that was in place at the time
the TIMSS study was conducted. The Pietermaritzburg data was collected by
administering a written test consisting of selected TIMSS 1999 science questions to a
randomly selected group of ten learners at each school follow ed by interviews with
the learners and the head of the Science Department at each school.
Learner ' notebooks and the year planners used by teachers at the three schools were
analysed primarily to check if these were in line with the SA intended curriculum
and to check for any possible sources of misconceptions. The analysis of the data
was guided by the constructivist theory and the conceptual framework used in the
TIMSS data. The TIMSS conceptual framework focused on the intended, the
implemented and the achieved curriculum.
The study found that learners hold misconceptions on different concepts of the
natural science curriculum. Some causes of misconceptions and errors among
learners were identified. Some of the misconceptions highlighted indicate for
instance that learners believe that boiling water is a form of a chemical reaction; a
seed develops from a root; proteins are the same as vitamins, proteins and vitamins
provide energy for the body. Some possible causes of misconceptions and errors among learners were identified. These possible causes of misconceptions and errors are varied with some for
example, linked to poor content coverage by teachers, learners' everyday experience,
the lack of learning resources and materials at some schools.
