Abstract:
The purpose of this study was to assess the science teaching efficacy of the Physical Science teachers in the secondary schools of the Free State province of the Republic of South Africa. Quantitative and qualitative methods were employed to gather data for this study. It was aimed at determining the effect of the demographic factors and the teachers’ level of preparedness regarding content knowledge and assessment skills on science teaching efficacy. The sample consisted of 190 Physical Science teachers. Two instruments were used to collect data: (1) A self-constructed questionnaire with the Science Teaching Efficacy Belief Instrument for in-service teachers (STEBI-A) modified for this study, and (2) Semi-structured interviews. Teachers’ biographical data and level of preparedness to teach Science were assessed against the two sub-scales of Personal Science Teaching Efficacy (PSTE) and Science Teaching Outcome Expectancy (STOE). Analysis of data was by basic statistics, descriptive statistics and inferential statistics using SPSS 20.0. Qualitative data were transcribed and categorised into emerging themes.
Analysis of the self-efficacy survey indicated highly positive self-efficacy beliefs expressed by most of the practising secondary school teachers in regards to Science teaching. Teachers believe in their own teaching abilities (Personal Science Teaching Efficacy beliefs) and they believe learners’ learning can be influenced by effective teaching (Science Teaching Outcome Expectancy beliefs). In addition, analyses of data on the respondents’ level of preparedness to teach Science indicated a high level of self-rated Science knowledge, with higher confidence levels in Physics than in Chemistry among in-service secondary teachers. MANOVA analysis indicated that teachers’ gender, teaching experience, professional and academic qualifications, Chemistry and Physics content knowledge, frequency of practical work, and confidence in conducting experiments played a significant role in the collective dependent variables, while the grades teachers taught, their age and learner assessments did not. Analysis further indicated that secondary school teachers with a B.Sc (Ed) degree had significantly stronger STOE than teachers with any other professional qualifications.

There was a significant difference between males and females in the STOE sub-scale scores (F=6.139; p=0.014) with males scoring higher than females; but no significant difference between males and females in the PSTE sub-scale scores (F=5.925; p=0.667). Moreover, teachers with at most five years and at least 16 years of teaching experience had significantly higher PSTE scores than teachers with different years of teaching experience. Furthermore, analyses of the level of preparedness in conducting practical work indicated that respondents were more confident to conduct Physics experiments than Chemistry experiments. In-service secondary Science teachers believed that assessment is an important and integral aspect of teaching and learning, hence they utilised a variety of assessment modes in their classroom.
It is recommended that further study should include a test in content knowledge, so that teachers can be assessed to confirm their confidence in content knowledge, rather than allowing them to rate themselves without an actual test. Moreover, qualitative studies may be conducted to support teachers’ self-report measures, such as classroom observations, in order to gain in-depth data about teachers’ efficacy beliefs. If more research is conducted on the self-efficacy beliefs of in-service Science teachers at secondary school level, the curriculum of teacher training programmes could be developed and structured further, there could be more understanding on what pre-service teachers face - this will help to understand how to motivate teachers to teach Science.
