Direct linkHewson, Mariana G.; Ogunniyi, Meshach B. – Cultural Studies of Science Education, 2011
An innovative school science curriculum in South Africa requires the inclusion of African societal/cultural knowledge, such as indigenous knowledge (IK). The main project involves introducing argumentation to accomplish this requirement. We used a focus group plus critical incident technique to ascertain nine teachers' understandings of…

Hewson, Mariana G. – 1978
Problems concerning conceptual change from existing knowledge (accumulated from everyday experiences or earlier teaching) to new scientific knowledge concerning natural phenomena are fundamentally the same for Western and non-Western students. However, difficulties experienced by non-Western students are magnified by factors such as their cultural…

Peer reviewedHewson, Mariana G.; Hewson, Peter W. – Journal of Research in Science Teaching, 1983
Investigated 90 Form Two students' (grade nine equivalent in USA) alternative conceptions and instructional strategies to affect change from alternative to scientific conceptions. Results indicate significantly larger improvement in acquisition of science concepts (mass, volume, density) by experimental groups resulting from strategies/materials…

Hewson, Mariana G.; Hewson, Peter W. – Journal of Research in Science Teaching, 2003
One of the factors affecting students' learning in science is their existing knowledge prior to instruction. The students' prior knowledge provides an indication of the alternative conceptions as well as the scientific conceptions possessed by the students. This study is concerned primarily with students' alternative conceptions and with…
