ABSTRACT

In this paper, we present a simulation of artificial selection of maize that can be used as a bridging case for the subsequent introduction of natural selection in school. The proposed simulation takes up essential biological elements but also has a cultural meaning for the inhabitants of some regions of Latin America. After implementing a test of the simulation with secondary school teachers, we identified fundamental ideas that are introduced as a result of participating in the simulation: intentionality, recognition of variants, gradual process and population. These ideas are relevant for understanding evolution as natural selection. Therefore, the simulation could be used as a bridging case because it focuses the attention on relevant ideas for artificial selection and leaves aside others that are not productive.

摘要

在本文中，我们提出了玉米人工选择的模拟，可用作随后在学校引入自然选择的桥梁案例。拟议的模拟包含基本的生物元素，但对拉丁美洲某些地区的居民也具有文化意义。在与中学教师进行模拟测试后，我们确定了参与模拟所引入的基本思想：意向性、变异识别、渐进过程和总体。这些想法与将进化理解为自然选择有关。因此，模拟可以用作桥接案例，因为它将注意力集中在人工选择的相关想法上，而将其他无效的想法放在一边。
