Studies show that students, within the context of mathematics and science, have difficulties understanding the concepts of the derivative as the slope and the concept of the antiderivative as the area under the curve. In this article, we present the Test of Understanding Graphs in Calculus (TUG-C...

Las relaciones entre trabajo y energía continúan siendo fuentes de problemas de enseñanza/aprendizaje en los cursos introductorios de física a nivel universitario, ya que implican conceptos abstractos y habilidades de metodología científica. Teniendo en cuenta los estudios anteriores en la litera...

Relations between work and energy are still a source of teaching-learning problems in the first years of university introductory physics courses since they involve abstract concepts and skills of scientific methodology. Considering the previous studies in the literature, the main objective of thi...
