What becomes of the learner who uses information and communication technology (ICT)? Case of the students in engineering of Tunis
It is evident that it is not easy to determine the multiple components and facets which a learner could have in a classic class situation considering the complexity, the character and diversity of such situations. However, on the basis of a didactic theoretical framework which illustrates the relations between a learner and technologies used in class, we will try to “remodelise” it so that we can set up...

A comparative study of problem-based and lecture-based learning in secondary school students’ motivation to learn science
Problem-based learning (PBL) is an innovative method involving problem-first learning via work in small group and independent study. With its promises, PBL is gaining popularity in higher institutions. The purpose of this study, therefore, is to compare PBL and lecture-based learning (LBL) in Senior Secondary School (SSS) students’ motivation to learn science. Eight-hundred and ten (810) science SSS II students...

High concentration ozone generation in the laboratory for various applications
Ozone (O3) the allotrope of oxygen is a powerful disinfectant and oxidant and nature’s agent for cleansing the environment. Ozone present in nature is only of sub-ppm level. In order to have ozone in large quantities, it is inevitable that same is produced artificially in a machine. In our laboratory, we have devised a novel and innovative plasma device for forming ozone in large quantities of thousands of ppm in...
