In 2014, evolution through natural selection was introduced to the primary science National Curriculum in England for year 6 (ages 10-11). As teachers had little prior experience of teaching this concept, it provided a rare opportunity to study the effectiveness of different approaches. A study was developed to investigate the impact of…

This paper presents an active learning approach that focuses on practical investigation of the ecosystem of tidal flats using 3D modeling and printing for biology students in order to enhance understanding of natural selection. The learning approach for the study followed a 5-step procedure: i) learning about 3D modeling and printing, ii)…

This paper gives an example of how to address the challenge of designing a learning progression that describes student thinking, with the necessary specificity to align instructional opportunities and assessment tools. We describe the Conceptual Underpinnings of Evolution project and the iterative process of developing a novel learning progression…

The "Next Generation Science Standards" ("NGSS") challenge prevalent beliefs that young children are "not ready" to understand natural selection, introducing core aspects in grades 1, 2, and 3 (NGSS Lead States 2013). The authors' research and teaching team engaged in a multiyear project to understand how early grades…

The phenomenon known as "essentialism"--the belief that all species have an essential form with variation being a form of accident of aberration from the essence of the species--is widespread and important because it is at odds with biological reality. The prospect of teaching children about inheritance and evolution would be undermined…

Evolution and inheritance appear in the new National Science Curriculum for England, which comes into effect from September 2014. In the curriculum documents, it is expected that pupils in year 6 (ages 10-11) should be taught to: (1) recognise that living things have changed over time; (2) recognise that living things produce offspring of the same…

Although children often characterize animals by the animals' color or pattern, the children seldom understand the evolutionary and ecological factors that favor particular colors. In this article, we describe two activities that help students understand the distinct evolutionary strategies of warning coloration and camouflage. Because both of…

Provides background information on how scientists have learned about the history of the Earth, including studying fossils, dating rocks, and tracing geological movements. Included are teaching activities about prehistoric animals, state fossils, tracing animal movement and evolution, and discovering fossils. Contains reproducible handouts and…

In this paper, I describe the action research I conducted in my third-grade science classrooms over the course of two years. In order to gain an understanding of my third-grade students' ideas about animal adaptations and how the teaching of a unit on crayfish influenced these ideas, I used clinical interviews, observations, and written…

The purpose of this curriculum guide is to help teachers implement the Alabama Course of Study: Science. The major emphasis of the guide is to provide student-oriented, hands-on activities that engage students in "sciencing" behaviors. This guide has two major components, the table of contents and the activities. The table of contents…
