Levrini, Olivia; Bertozzi, Eugenio; Gagliardi, Marta; Tomasini, Nella Grimellini; Pecori, Barbara; Tasquier, Giulia; Galili, Igal – Science & Education, 2014
The paper deals with physics teaching/learning in high school. An investigation in three upper secondary school classes in Italy explored the reactions of students to a structuring lecture on optics within the discipline-culture (DC) framework that organises physics knowledge around four interrelated fundamental theories of light. The lecture…

Some Reflections on Plane Mirrors and Images.
Peer reviewed Peer reviewed
Galili, Igal; And Others – Physics Teacher, 1991
Discusses the following questions based on the assumption that students' personal experiences and prior beliefs about plane mirrors can promote interesting discussions: (1) How mirror images are formed? (2) Why doesn't paper behave like a mirror? (3) Does a mirror left-right reverse objects? and (4) Why are corner images of two perpendicular…

The Effect of a History-based Course in Optics on Students' Views about Science.
Peer reviewed Peer reviewed
Galili, Igal; Hazan, Amnon – Science and Education, 2001
Describes an experimental course in optics for 10th grade high school students. The course incorporates those historical ideas, views, and conceptions that constituted the early understanding of light and vision. Presents a part of the course which assesses its impact on students' views about science and some related technological and cultural…

Flux Concept in Learning about Light: A Critique of the Present Situation.
Peer reviewed Peer reviewed
Galili, Igal; Lavrik, Valentina – Science Education, 1998
Investigates high school students' knowledge of natural phenomena related to the concept of light flux as it applies to the seasons and illumination after they studied optics. Discusses didactic, cognitive, and ontological perspectives in relation to specific changes in the science curriculum. Contains 71 references. (DDR)

Learners' Knowledge in Optics: Interpretation, Structure and Analysis.
Peer reviewed Peer reviewed
Galili, Igal; Hazan, Amnon – International Journal of Science Education, 2000
Explores high school students' and preservice teachers' knowledge of light, vision, and related topics before and after commonly practiced instruction. Suggests a hierarchical structure to represent the collective conceptual knowledge of students and teachers in terms of facets and schemes of knowledge. Makes suggestions for designing instruction…

The Effects of Prior Knowledge and Instruction on Understanding Image Formation.
Peer reviewed Peer reviewed
Galili, Igal; And Others – Journal of Research in Science Teaching, 1993
Reports a study (n=27) concerning the knowledge about image formation exhibited by students following instruction in geometrical optics in an activity-based college physics course for prospective elementary teachers. Student diagrams and verbal comments indicate their knowledge can be described as an intermediate state: a hybridization of…
