    Determination of university students’ misconceptions about light using concept maps
    (Elsevier, 2014) Blizak, Meriem Djanette; Chafiqi, Fouad
    The concept map has evolved, in recent years, as an important teaching and learning tool. It engages students in active learning and assists instructors with their delivery. Thus, we believe that it has the power to be relevant and effective to reflect the design of a poly-functional teaching tool. We argue in favor of renewing didactic tools used in education, in general, and in teaching GO (geometric optics) in particular. The main purpose of this study, however, is to show that the concept mapping is a very effective way in terms of revealing the misconceptions of students, studying GO, during their university year. 52 freshman students (first year) majoring in life science and nature (LSN) were asked to draw a conceptual map about propagation of light; a two-stage experiment: before and after formal teaching sessions. The findings of the qualitative analysis of the students’ maps are in line with the results of other research; students have many misconceptions about light and traditional strategy used for teaching GO is not effective for conceptual change. Also, The approach of scoring tasks, as only one survey is not recommended

    Students misconceptions about light in Algeria
    (2009) Blizak, Meriem Djanette; Chafiqi, Fouad; Kendil, Djamel
    Physics education research has shown that students have difficulties in learning essential optics concepts. Therefore, in this present work we deal with student’s conceptions in geometrical optics field. Our objective is to show the Algerian students misconceptions. We proposed to 246 students in first year university (aged 18–21) a closed questionnaire where most of its questions were already used by other researchers. The misunderstandings identified were compared with those in literature. The results show that our students have the same misconceptions, related to the propagation of the light, the vision, the refraction and the reflexion, as the students in other countries (Andersson, Çiğdem ŞAHİN, Galili, Goldberg, Viennot,…). We investigate new students “misconception” concerning the propagation of the light in the vacuum

    What thinks the university's students about propagation of light in the vacuum?
    (2013) Blizak, Meriem Djanette; Chafiqi, Fouad; Kendil, Djamel
    This study aims to study the conceptions of university students related to the notion of propagation of light in a vacuum. In order to fulfill our aim, a case study research method was used in the study, whose sample consisted of 321 Algerian undergraduates in different levels at science faculty (before and after the optics courses). The data were collected through a test comprising three questions. The results have indicated two students’ misconceptions concerning propagation of light in vacuum. The first one is that the light does not propagate in a vacuum. The second is that the light propagates according the horizontal direction (new misconception). The possible origins of these misconceptions are discussed and suggestions for how to prevent them are given. Also, our results suggest that university students who had a higher level of physics knowledge than their counterparts who studied only geometrical optics, they still held of the same misconceptions. Formal or traditional teaching seems helpless to facing these misconceptions
