Thesis (MEd) -- University of Stellenbosch, 2009. / ENGLISH ABSTRACT: Learning and the development of numeracy in the foundation phase are regarded as highly important. In this critical period learners attain the fundamental knowledge that is needed for future learning and development. A serious problem within South African schools is that a great number of foundation phase learners show difficulties in numeracy. Various reasons can be provided for these difficulties, for example, learners do not receive good teaching, they hold negative attitudes towards numeracy, they encounter language barriers, and so forth. It is important that the learners’ difficulties in numeracy are attended to immediately and effectively, to be able to minimise the gaps between the learners’ functioning level and the level the learner is suppose to be on. The Western Cape Education Department (WCED) laid bare their concern with the current problem in numeracy when they launched the WCED Literacy and Numeracy Strategy 2006-2016. As part of this the Metropole North Education and Management Development Centre (EMDC) requested and implemented an intervention programme for grade 2 and grade 3 learners. Part of this problem is that many foundation phase educators lack the necessary knowledge to identify the learners with difficulties and especially to attend to these difficulties. The goal of this research study was to investigate the realization of an early intervention programme implemented over a limited period of time of ten weeks in grade 2 and grade 3 classrooms. The current study aimed at providing educators with resources to offer learning support to their disadvantaged learners within the Numeracy classroom. This study has implications for the way in which educators approach and teach numeracy, as well as for the type of learning support the educators provide their disadvantaged learners with. The intervention programme is based on a problem centered approach with constructivism as underlying epistemology. This approach views the educator as a facilitator who provides the learners with opportunities to be actively involved in the learning environment to construct knowledge. The importance of word problems and discussion within the Numeracy classroom are emphasized and it is necessary that the educator create the appropriate classroom atmosphere so that this approach can be implemented effectively. Learning is an active process and it is the responsibility of the educator to provide the learners with appropriate learning activities for learning and development to take place. The study made use of programme evaluation as research methodology. Programme evaluation refers to a research goal instead of specific research methods, because various methods can be used which may be quantitative or qualitative in nature. The gathering of data was done through classroom observations by the researcher, informal interviews with participating educators, questionnaires, and semi-structured interviews with the educators at the four schools the researcher monitored intensively during the implementation process of the intervention programme. The gathering of data was an ongoing process and the researcher analysed and interpreted the learners’ work at the end of the implementation process. The researcher checked this analysis by means of the literature review, transcripts and field notes. This formed the basis on which conclusions and recommendations could be made. The conclusions confirmed the importance of early intervention and the efficacy of the problem centered approach within the numeracy classroom. It also confirmed the disadvantages of the training model that was used, that is the Cascade model. With this study it was possible to determine that a ten week intervention programme was too short a period to observe meaningful improvements in learners. Therefore further research should be done on addressing learners’ difficulties and to train and support educators to provide learning support to their learners.
