Against a backdrop of advocacy for interdisciplinary STEM curricula, this paper explores the design principles underpinning a three-year longitudinal research project that develops and evaluates interdisciplinary mathematics and science learning sequences involving multiple teachers and student cohorts across the primary school years. The research…

Learning about heredity is important across the K-12 continuum. However, these ideas may be challenging for students. We examined third-grade students' ideas about heredity in the context of a new, six-week, model-based science unit that uses corn as a model organism to support students' ideas about heredity. We analyzed data collected during…

The diet of many students consists of on-the-go processed food. As part of a larger school garden project, the authors wanted students to consider the relevance of plants in their own lives, both as food sources for us and for the animals that we eat. In this article, they present a mini-unit they taught in a third-grade classroom that helped…

With the adoption of the Common Core State Standards for Mathematics (CCSSM) (CCSSI 2010), many concepts related to area are covered in third grade: (1) Recognizing area as an attribute of a plane figure; (2) Understanding that a square with a side length of one is a unit square; (3) Measuring area by tiling figures and counting the squares it…

The purpose of this study was to explore the effects of the context-aware ubiquitous learning (u-learning) approach versus traditional instruction on students' ability to answer questions that required different cognitive skills, using the framework of Bloom's taxonomy of educational objectives, including knowledge, comprehension, application,…

Elementary students should have opportunities to develop scientific models to reason and build understanding about how and why plants depend on relationships within an ecosystem for growth and survival. However, scientific modeling practices are rarely included within elementary science learning environments and disciplinary content is often…

Not only is science perceived by some as a hard-to-teach subject, but there are certain topics that all teachers regard as notoriously hard to teach. While their natural inclination may be to eliminate some of the details, teachers have to be careful not to water down the curriculum. How do they share the complexity of the natural world without…

Take plant lessons outdoors with this engaging and inquiry-based activity in which third-grade students learn how to apply soil conservation methods to growing plants. They also collect data and draw conclusions about the effectiveness of their method of soil conservation. An added benefit to this activity is that the third-grade students played…

Although the teaching of photosynthesis occurs yearly in elementary classrooms, one thing that makes it challenging is the inclusion of English language learners (ELLs). This article presents several activities for teaching and assessing of photosynthesis in a third grade classroom. The activities incorporate the photosynthesis content, teaching…

The purpose of this study is to investigate the effect of the use of group works and demonstration experiments based on conceptual change approach in the elimination of misconception about the subject of photosynthesis and respiration in plants in pre-service science teachers. This study was conducted with 78 pre-service science teachers including…

The inspiration for this article was not conceived over lunch, but more specifically over the box in which the lunches were packaged. Five colleagues brainstormed ideas for teaching a unit on trees for the third grade that would fit in our boxes. The disciplines involved were art, children's literature, science, social studies, and technology.…

Tree rings can be used not only to look at plant growth, but also to make connections between plant growth and resource availability. In this lesson, students in 2nd-4th grades use role-play to become familiar with basic requirements of trees and how availability of those resources is related to tree ring sizes and tree growth. These concepts can…
