The two-part Views on Chemistry Practicals (VOCP) instrument for measuring the views of grade 10 to 12 Physical Science students about the benefits and problems of Chemistry practicals was empirically developed and trialed using six schools in Gauteng. The summary part of the resultant VOCP instrument comprises 24 Likert items and the explanatory part comprises 24 multiple-choice items with 163 options, thus creating a unique current record of a wide range of students' views of chemistry practicals and providing teachers with a tool for improving chemistry practicals. The trial of the instrument with 230 students from three schools indicated that the summary part of the instrument is reliable (Cronbach alpha coefficient) and that a shortened explanatory part of the instrument is reliable (Chi squared values for 17 items with 98 options). The validity of the VOCP instrument was established through the empirical development of the instrument using triangulation of data. / Educational Studies / M.Ed. (Natural Science Education)
