Since the adoption of the "No Child Left Behind Act," states have had to adopt rigorous, K-12 academic science standards to secure federal funding. Corresponding to this legislation and a concurrent call for equitable, relevant science standards, the "Next Generation Science Standards" were developed. As the country learns to…

Simplified, reductionist approaches to curriculum design and delivery are pervasive in science education. In ecological curricula--particularly in, but not limited to K-12--biomes, ecosystems, habitats, and other units of study are simplified and presented as static, easily identified and described entities. Characteristics, components, and…

In this article, we compared French and Cameroonian schoolchildren's initial conceptions and comprehension of the night and day cycle in order to test for cultural influence. Forty students aged almost 8 years (Grade 2) were individually interviewed in their schools about night and day dynamics before they had received any teaching in astronomy.…

To understand students' argumentation abilities, there have been practices that focus on counting and analyzing argumentation schemes such as claim, evidence, warrant, backing, and rebuttal. This analytic approach does not address the dynamics of epistemic criteria of children's reasoning and decision-making in dialogical situations. The common…

Kim and Roth (this issue) purport to draw on the social-psychological theory of L. S. Vygotsky in order to investigate social relations in children's argumentation in science topics. The authors argue that the argumentation framework offered by Stephen Toulmin is limited in addressing social relations. The authors thus criticize Toulmin's Argument…

The interaction analysis presented by Kim and Roth examines nine students, their teachers, the learning task and materials in a mixed second and third grade science classroom during the school day. In the research narrative readers are introduced to two resourceful and creative groups of students as they work on a task assigned by their…

In this paper we investigate how the bodily activity of teaching, along with the embodied aspect of lived experience, relates to science teachers' ways of dealing with bodies as living organisms which are both the subject matter as well as the site or vehicle of learning. More precisely, the following questions are pursued: (1) "In what ways…
