According to Richard K Moran, and Page K, in “ Teaching for Conceptual Understanding in Science”, conceptual understanding is one that is consistent and compatible with scientific knowledge or language of science accepted by the scientific community, not language of incorrect terminology or everyday life used by nonscientists that has different meaning. It is agreed between educators at the present time that students come to school and they have ideas and interpretations does not correspond with what scientists reach of acceptable ideas. Such ideas and interpretation called children’s ideas, alternate conceptions, or wrong understanding. Such understanding is not compatible and consistent with appropriate conceptual understanding. …show more content…
For example, let’s take photosynthesis as an example; Photosynthesis is one of the metabolic processes as building carbohydrates that form the basis for making the rest of the food from proteins and fats, which is made up from the bodies of living things. Students’ understanding for this process affects their understanding for respiratory process in the plant. As a result, when students have an understanding of Photosynthesis concept appropriately, they can use in areas other than that in which they learned it and also affect their understanding of reparatory process and the relationships between them. Science teachers should find strategies and techniques for getting rid of and preventing the formation of students’ naïve preconception misconceptions or alternate conceptions by using a conceptual change strategy in order to facilitate occurring meaningful learning. Conceptual change curve is considered as one of the most important strategy used to achieve this purpose. This supposes that the students work actively and logically by replacing scientifically acceptable explanations instead of misconception. Strike and Posner suggest that in order for change to occur, 4 conditions are necessary: the students must have dissatisfaction with their existing ideas and views; the new conception must be more clear, intelligible, and attractive; the new conception must appear initially acceptable, and plausible; the new conception must open new lines of inquiry and have explanatory and predictor power in new situations and attitudes. In conceptual change texts strategy, students are asked to describe the phenomenon being investigated and predict what happens based on what they already have of past knowledge or prior ideas before providing them with
