Bystander cardiopulmonary resuscitation improves survival after out-of-hospital cardiac arrest. This study aimed to assess the effectiveness of a basic life support (BLS) educational course given to 110 middle school children, using a pretest posttest design. In the pretest, students were asked to demonstrate BLS on a manikin to simulate a…

GeoGebra is a dynamic geometric software developed for the support of mathematics teaching. The aim of this research was to study the effect of GeoGebra on mathematics achievement in relation to the linear equations and explore the perception of students towards the use of GeoGebra in teaching mathematics. Forty students were participating in this…

This article presents the development and testing of a content-based video exchange model as a motivating means to introduce lower secondary English learners to English as the language of science. The central goal was that students reach the required curricular content knowledge despite learning some of the content in a foreign language. The model…
