Home language can determine just how well pupils perform
Tackling language policy could make all the difference in improving pupils' performance and producing the skilled labour that our country needs, as pupils perform better when they understand instruction because it's taught in their home language.

Pupils who have access to physical educational resources, such as books and computers at home, tend to perform better in science than those who don’t.

This has been proved by a great deal of international research.

It’s true in South Africa, too, but our research has found that less tangible factors also play a role in pupils’ science achievement.

These factors include parental education levels, parental involvement in homework – and, crucially, home language.

Language is a factor that makes the South African context unique and has a noteworthy role in pupils’ science achievements.

The language of teaching and learning is often different from the language spoken in a pupil’s home.

Only 26% of pupils who participated in the 2011 Trends in International Mathematics and Science Study (TIMSS) spoke the language of the test at home.

For our research, we studied data from 11 969 Grade 9 pupils – who were, on average, 16 years old – who participated in TIMSS in 2011.

Successive apartheid governments used language policy as a tool to create socio-economic and educational division. This history means that language as a home resource can’t be overlooked when it comes to understanding pupils’ performance in science at school.

Our results proved just how important language is: the language most often spoken in a pupil’s home was the single most important predictor.

In developing countries such as South Africa, science, technology and innovation have become forces that drive economic growth and competitiveness and have the potential for improving the quality of life.

The number of skilled people (such as scientists, engineers and other technically skilled personnel) in a country is associated with its economic growth and ability to compete in the global economy.

The development of these skilled people begins at the school level.

So it’s cause for concern that the 2011 TIMSS found the average science achievement of Grade 9 South African students to be well below the international centre point of 500 points.

Tackling language policy can, we believe, improve pupils’ performance in this important subject.

Findings

Historically, the state provided educational resources in an unbalanced way.

Schools designated for white pupils were well resourced, while those for black learners were under-resourced.

Today, these imbalances persist. There are vast differences in physical resources at poor and affluent schools.

The school resources we included in our study were the condition of the school building; the use of workbooks or worksheets as the basis of instruction and class size.

We also explored the capacity of the school to provide instruction based on the availability of resources such as textbooks, science equipment and computer software.

For home resources, we asked the pupils to report on how often the language of the test was spoken in the home, the number of books at home, the number of home assets, parental education levels, and parental involvement in school homework.

Language emerged strongly as a success factor.

Pupils who used the language most frequently spoken at home in the TIMSS test scored 62 points higher, on average, than those who seldom spoke the language of the test.

The number of home assets present in a pupil’s home had the second strongest positive association with science achievement.

It was found that for each additional asset (such as a fridge, television, computer etc.) in a pupil’s home, they scored an average of 11 points higher in science than their peers.

The third most important predictor of science achievement was the condition of the school building.

Pupils who attended schools with minor problems with the building performed 24 points higher, on average, than those who attended schools that reported moderate to serious problems with the buildings.

So what does this all mean?

Implications

Language development is recognised as crucial for all other learning to take place.

Our findings suggest that the language of instruction (and of testing) has not been mastered by the time pupils are in Grade 9.

This is unsurprising. Most of the learners who were tested using TIMSS were, in essence, learning science through a foreign language.

This means that pupils are likely to be at a disadvantage because their knowledge of the language of instruction is below the expected level for their age and grade.

The implication is that education policies must seek both to improve the manner in which the language of instruction is taught to students who don’t speak that language at home, and concurrently, the policies that promote instruction in the home language must be strengthened.

It’s important that we understand the determinants of science achievement for South African pupils.

This has far reaching implications for the country’s broader growth and development.

This is because successful interventions at school level may contribute to increasing the pool of matriculants who are eligible to study science-related subjects at a tertiary level and who will later join the skilled workforce.
