Its treatment by tutors sometimes becomes very difficult such that some tutors handle the subject theoretically and/or in abstraction. As a result, most students find the topic difficult to comprehend. In view of this, the DTML-Conversion model (i.e. the D-Conversion model (i.e. distance), the T-Conversion model (i.e. time), the M-Conversion model (i.e. mass) and the Reverse L-Conversion model (i.e. litre)) was designed. The DTML-Conversion Model is created by the researcher to make the teaching and learning of conversion in measurement more manageable for tutors and less troubling for students. The presentation will demonstrate one component of the model (the Distance-conversion functions) and how it can be effective in the teaching and learning of unit conversions.enConversionabstractionteaching and learningmeasurementArticle
