Dans cet article est présenté un spectre des remarques synthétiques par rapport au rôle des variables dans l’enseignement expérimental en sciences. Au début, nous discutons des aspects importants et pertinents de la gestion des variables dans les expériences comme le changement d’une seule variable et la construction des tableaux. En plus nous nous référons aux situations expérimentales complexes, aux erreurs, aux attitudes et à la séparation des variables. In this article is presented a spectrum of the synthetic comments related to the role of the variables in the teaching science experiments. At the beginning we discuss important and critical aspects of manipulating variables in experiments as the change in one variable and the construction of the tables. In addition we refer to complex experimental situations, errors, attitudes and the separation of variables.

The Problems Observed During Carrying Out Physics Experiments In Elementary Science Lessons At Schools Which Have Different Socio-Economic Levels2016 •
During the teaching process of physics, the teaching materials serve as a theoretical foundation forthe students so they gain practical theoretical skills while learning. On the other hand, while teaching physics,one should put to good use the skills and the knowledge that the students gain from various sources ofinformation. Solving each problem in physics, whether in theory or in practice, is a scientific research process inminiature, a modest act of creation. Knowledge on physics should be treated on the basis of observation andconcrete analyses of phenomena both in nature and in classrooms being supported by the study and thereproduction of physical phenomena via physical experimentation. The experiment should be broadly used, andshould be considered as an important source of new teaching information to experimentally prove the raisedhypothesis and/or ideas and theoretical conclusions drawn earlier, during control and estimation of theknowledge of students, during repetition, as...

What is the Purpose of This Experiment? Or Can Students Learn Something From Doing Experiments?2000 •
2012 •
The primary objective of performing a physics experiment is to gain procedural as well as conceptual understanding. Some of the researches reported in Physics Education emphasize the importance of introducing innovations in physics experiments so as to improve clarity as well as the depth of learning experiences. In this paper, we report the impact of seven experiments designed in different branches of physics and systematically tried on college students. We observe a significant enhancement in the conceptual understanding of the students after exposure to the treatment.
