What is it?
Oral language interventions emphasise the importance of spoken language and verbal interaction in the classroom.
They are based on the idea that comprehension and reading skills benefit from explicit discussion of either the content or processes of learning, or both. Oral language approaches include:
- Targeted reading aloud and discussing books with young children
- Explicitly extending students’ spoken vocabulary
- The use of structured questioning to develop reading comprehension
All of the approaches reviewed in this section support learners’ articulation of ideas and spoken expression, such as Thinking Together or Philosophy for Children. Oral language interventions therefore have some similarity to approaches based on Meta-Cognition, which make talk about learning explicit in classrooms, and to Collaborative Learning approaches, which promote students’ talk and interaction in groups.
How effective is it?
Overall, studies of oral language interventions consistently show positive benefits on learning, including oral language skills and reading comprehension. On average, students who participate in oral language interventions make approximately five months' additional progress over the course of a year.
All students appear to benefit from oral language interventions, but some studies show slightly larger effects for younger children and students from disadvantaged backgrounds (up to six months' benefit). Likewise, some types of oral language interventions appear, on average, to be more effective than others.
There is consistent evidence supporting reading to young children and encouraging them to answer questions and to talk about the story with a trained adult. Conversely, ‘whole language’ approaches, which focus on meaning and personal understanding, do not appear to be as successful as those involving more interactive and dialogic activities. A number of studies show the benefits of trained teaching assistants effectively supporting both oral language skills and reading outcomes.
For all oral language interventions certain factors are associated with higher learning gains, suggesting that careful implementation is important. Approaches which explicitly aim to develop spoken vocabulary work best when they are related to current content being studied in school and when they involve active use of any new vocabulary. Likewise, approaches that use technology are most effective when technology is used as a medium to encourage collaborative work and interaction between students, rather than a taking a direct teaching or tutoring role. Most studies comment on the importance of training and teacher development or support with implementation.
There is very little Australasian-based research examining the effectiveness of school-based oral language interventions in improving students’ verbal or literacy skills. The few studies published involve explicit oral language instructions or the incorporation of oral language by teachers in their lessons. The studies tend to show positive gains.
How secure is the evidence?
There is an extensive evidence base on the impact of oral language interventions, including a substantial number of meta-analyses and systematic reviews. The evidence is relatively consistent, suggesting that oral language interventions can be successful in a variety of environments. Although the majority of the evidence relates to younger children, there is also clear evidence that older learners, and particularly disadvantaged students, can benefit.
What are the costs?
Overall, the costs are estimated as very low. There are few, if any, direct financial costs associated with this approach, though some additional resources such as books for discussion may be required. The cost of these resources is estimated at between $20 and $40 per student. Professional development or training is also likely to enhance the benefits on learning.
What should I consider?
How can you help students to make their learning explicit through verbal expression?
How will you match the oral language activities to learners’ current stage of development so that it extends their learning and connects with the curriculum?
What training will the adults involved have to ensure they model and develop student’s oral language skills?
If you are using technology, how will you ensure that students talk about their learning and interact with each other effectively?
