This paper describes an approach to the problem of teaching first year tertiary level mathematics students who have widely varying levels of achievement and ability in mathematics. The evaluation of some aspects of the proposed solution to the problem is based on a semantic differential and a Likert-type questionnaire. © Taylor & Francis Group, LLC.

A site investigation was carried out to determine the axial deformations of a column in a tall reinforced concrete building. Strains were measured in the column concrete using vibrating wire gages and the column deformations were measured by precise leveling. In addition to strain measurements on standard laboratory shrinkage and creep specimens, strain data were obtained from tests that related more closely to the site conditions. Appreciable differences occurred between shrinkage and creep strains measured in the laboratory and some of those obtained by methods given in codes. Shortcomings were found in some of the equations used to predict long-term creep strains from laboratory data and a hyperbolic equation was developed that enabled more accurate predictions to be made. Measured strains in the column were compared with predicted values obtained by two calculation methods and good agreement was obtained.
