A student's cultural background affects his or her learning they do impact students' learning.
Culture includes what people actually do and believe. Culture strongly influences how we see the world, how we try to understand it, and how we communicate with each other. Therefore a culture largely determines the style of learning and teaching. Students may come from homes where children are being told to be seen rather than heard.
Working and learning with people from different backgrounds and cultures in the classroom helps students develop a more complete understanding of the subject matter. It also teaches students how to use their strengths and perspectives to contribute to a diverse work environment. Building trust and fostering stronger relationships results in student engagement, greater motivation, and enthusiasm for learning together.
The bottleneck effect is the sharp in the population size due to the fact of the environmental changes such as the famines and the floods and the diseases and other events that lead to the variation in the gene pool s and thus a reduction of the species with a smaller remaining genetic diversity. The genetic drift causes the bottlenecks and this can create a random alternation of the alleles and leads to the loss of the species.
