This study aims to analyse the mental model of secondary school students on the topic of Sun-Earth-Moon system, focusing on Moon phases and eclipses. That for, an open-ended questionnaire was designed and implemented with 265 secondary school students whose answers were analysed with phenomenography. The identified difficulties were similar to the ones obtained in the studies found in the...
This work reports on the administration of an online, interactive survey, assessing the estimates of N=201 high school students on astronomical scales. Five questions were asked, two of which probing estimates on the relative sizes of astronomical bodies, and three on the relative distances between them. We investigated the effects of different question formulations and customised...
Despite educators' efforts using various representations of the celestial sphere to help students reason about the apparent motion of the Sun and stars, this concept remains challenging for students. It is hypothesised that they may not fully grasp the underlying model of the celestial sphere, including its possibilities and limitations. This study aims to explore how secondary school students...
Tidal movement is a fascinating phenomenon, but often plagued by misconceptions among students and teachers. This presentation offers physics teachers a clear, accessible model of the frozen (equilibrium) tide, i.e. the tidal movement on an all-ocean world. Using simple expressions for tidal acceleration, water height, and power loss, it provides key insights to address common misconceptions....
