Demonstrations are a core part of science teaching. In 1980 a three-part assessment method using demonstrating was proposed. Known as DOE this consisted of demonstration, observation and explanation. DOE quickly evolved into POE: predict, observe, explain. In the light of experiences with POE and insights from constructivist theory we set out in…

Chemistry teachers face constraints when trying to integrate cognitive and affective objectives, and hence thoughtful lesson planning is required to achieve the goal. Chemistry teachers can educate students to be knowledgeable about chemical concepts, processes and the benefits of responsible practice by the chemical industry, while being aware,…

Proposes a model of critical thinking in science with affective (dispositions), cognitive (knowledge, basic skills, and higher order skills), and behavioral (contextualized or generalized behaviors) components. Describes the links and mutual influences between the environment and these components. Emphasizes the role of affectivity in the…

Proposes a diagrammatic model connecting the cognitive and affective domains of educational objectives, abandoning Krathwohl's hierarchy of affective objectives for one based solely on arousal of interest as a positive dimension. A negative dimension for the hierarchy is also suggested and research evidence supporting the model is given.…

Part 1 (SE 533 869) traced history of physics textbooks and discussed texts produced from 1850 to 1870. This part examines aims/methods of physics teaching, textbook style, and cognitive/affective aspects of physics textbooks. Factors that influence the writing and preparation of the texts are also considered. (JM)
