ItemA cartoon chemistry text : the construction and testing of a novel chemistry text incorporating human values( 1990)This study examines current science texts and the concerns and objectives of Science-Technology-Society based courses. It indicates that they present the public image of the practising scientist (with inherent Mertonian values of Universalism, Communism, Disinterestedness, and organized skepticism) which is used to organize scientific concepts into a meaningful whole. Utilizing the notion that a value is anything important to a student, a hypothesis was proposed that meaning and interest generated from a text is dependent on the extent of overlap between text and student values. The implications of the interaction of different value systems with a Mertonian based text were considered. An attempt was made to develop a chemistry text that was meaningful to all students, by organizing concepts into a story form with non-Mertonian organization. This approach evolved into a cartoon format with specific features. Two cartoon text items were tested at two schools. The trial involved a survey item on 103 students and audio taped interviews with 20 students. The trial attempted to evaluate the cartoon as a student text, attitudes to issues content, and styles of resolving issues based conflicts. The results were interpreted by classifying the respondents into four categories of science likingness ( A, B, C, D) on the basis of Year 11 subject choice, and favorite subject. It was assumed that the accommodation of Mertonian values by a group reflected the science likingness of the group. The cartoon text was well received with most students wishing to see more cartoons, and being able to answer questions from the text. The B, C, and D groups expressed a preference for the cartoon text over their current science text. The proposed differential accommodation of values appeared to account for the greater enthusiasm of the B and C groups for the cartoons than the A and D groups. Perceptions of the amount of current social problems/ issues content in science teaching increased markedly with group science likingness. The amount of issues content desired decreased with increasing group science likingness. A belief that scientific solutions could resolve social problems/ issues, showed a marked decrease with decreasing science likingness. A value model of cognitive style was developed from the basic hypothesis and assumptions regarding the extent of accommodation of Mertonian and Humanist norms as personal values. This model seemed to account for variations in meaning generated for the various groups in response to both the standard and cartoon science text format.
