The aim of this study is to determine the effect of using computer simulation on students’ performance in teaching and learning physical science, particularly the electrical Ohm’s law. A sample of 182 students classified into two groups–experimental (92) and control (90)–from two middle schools in Meknes city (one in the rural area and the other urban area) was the subject of a pretest and posttest evaluation. The outcomes of the administered test to both groups of students, control and experimental, were compared and analyzed using Student’s t-test and the Mann–Whitney U test with Statistical Package for the Social Sciences (SPSS). The results obtained suggest that the experimental group register the best performances after the posttest than the control group (
p
<
0.05
). While no difference, in terms of performance, was signed according to gender in the experimental group (
p
>
0.05
), the urban students were more successful than the rural ones, with and without the use of simulations. In this respect, this study recommended using and practicing simulation software to improve and develop the performance of middle school students.
This paper presents a study of the solar dome system that is considered as one of the most important economical solutions in the domain of drinking water production. For this, a mathematical model was built from equations describing the optical and thermal phenomenon involved in this process. The concentration of radiation and the heat flow were simulated in each 0.1m² of the dome using the metrological parameters of Morocco’s region Rabat-Salé-Kenitra. The results can follow the evolution of the temperature of glass, salt water, point dew temperature, saturation pressure and evaporation rate as well as humidity reached in August month for the study zone. For this, a numerical implementation on Matlab and Ansys are compared with measurements for the same parameters shown in the domain study of single slope. The comparison results are more significant by the rise of the ray concentration rate reached to 99% if the inclination angle of the heliostat is divided into three intervals. The saturation pressure increases as long as with the rate of evaporation and the humidity that produces ordinary daily fresh water.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
