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 ( ). While no difference, in terms of performance, was signed according to gender in the experimental group ( ), 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.

Sustainable agriculture is fundamental to strengthening the resilience of rural communities to climate risks. This article aims to integrate traditional and scientific knowledge by identifying the types of proximity and the modes of valorisation of the territorial resource “rose” activated by the territorial actors of a localised agri-food system (LAFS), specialised in the production and processing of fresh rose in Kalâat M’gouna (K-M), Province of Tinghir in Morocco. The objective is to show to what extent the logics of proximity activated allow for the inclusion/understanding of the mechanisms of resource valorisation implemented by the actors. In other words, we seek to see whether the activation of several types of interaction between actors can promote the emergence of new modes of valuing the rose resource. This will be done by analysing the level of valorisation of the “rose” resource by the actors of this system while proposing tracks of improvement to take part in the sustainable development of this traditional system through its orientation towards the cognitive and innovative aspects. Our methodology is based mainly on a case study of a localised agri-food system (LAFS) using a set of semi-directive interviews conducted with 47 different actors of the system. Thus, we relied on SPSS software to study the possible correlations between the types of proximities existing and the modes of resource valuation activated. In terms of results, we were able to verify the domination of traditional proximities (geographical, organisational, relational, etc.) at the level of interactions between actors. On the other hand, there is a kind of insufficiency of the relations which are based on the knowledge and the (cognitive) knowledge.
