    ENGLISH SUMMARY: Instructional pictures can significantly facilitate recall, comprehension and problem-solving skills. This learning effect is robust and can be achieved with a variety of learners, text, pictures, media, and learning conditions. Pictures can also distract from the learning process and interfere with the process of learning how to read. People can experience difficulty in utilising pictures in picture-text learning material due to unfamiliar graphic conventions and inadequate visual and verbal literacy skills. The aim of this study was to investigate the use of pictures in picture-text learning material, and in particular the value of culturally modifying pictures in such material to increase the learning facilitation effect. The focus was on learners from developing communities. The study consisted of four phases: the development of a theoretical foundation through a literature study; an empirical component that investigated the effect of culturally modified pictures when they are combined with printed educational text; recommendations for the design and development of picture-text learning material; and the development of a model that explains and predicts pictorial learning facilitation. The literature study isolated twenty-two general factors that influence the learning effect of pictures and a further ten factors applicable to learners from developing communities. Nineteen principles were identified that can improve pictorial material that is used in educational material, health education and development programmes. Culture was shown as a filter through which people receive, interpret and transmit messages. The literature study concluded with a model that projected the picture-text-communication process in education as an open system, which takes place within a cultural environment. More than seven hundred subjects participated in eight experiments. The results have shown that culturally modified pictures do not necessarily increase recall, comprehension or problem-solving abilities more than instructional pictures that are not culturally sensitised or modified to their audience. Subjects have shown that they prefer pictures that are modified to their own culture. Culturally appropriate and relevant graphic elements and conventions might not necessarily reveal measurable cognitive value, but are important elements in instructional picture-text learning materials that are specifically aimed at developing and undeveloped communities. The study proposed a learner-centred theory for pictorial learning facilitation, seven principles for the design and development of picture-text learning material, and an analytical model that instructional designers can use during a formative and evaluative process of pictures in picture-text learning material. The main contribution of the study is a model for the explanation and prediction of pictorial learning facilitation in picture-text learning material. This model provides the means to use existing and anticipated data to predict the effect of picture-text learning material in a specific learning situation with specific learners. It also provides a means to explain the results of a picture-text learning occurrence. Sociocultural variables in text and pictures play an important role in picture-text learning material when such material is aimed at learners from developing communities. These variables become less important when the subjects move towards an urbanised, developed and heterogeneous community. Cultural appropriateness in pictures can affect the congeniality of picture-text learning material, but does not necessarily contribute on a cognitive level to the value of picture-text learning material. Inappropriate cultural conventions in text and pictures can, however, create a barrier in communication and thereby affect the cognitive value of such learning material.
