Classroom talk is frequently limited, often used to check student comprehension rather than develop thinking. In classrooms with higher numbers of students living in poverty, teachers talk more and students talk less (Lingard, Hayes, and Mills 2003), positioning students as passive learners, which is problematic to developing critical thinking.…

This column presents ideas and techniques to enhance science teaching. In today's classrooms, teachers face numerous challenges. They are preparing students for jobs and careers that are not even conceived of yet. Assessments are being used to address students' college and career readiness and to promote critical thinking and problem solving.…

This article describes a two-day lesson in which fifth-grade students took on the role of marine biology scientists, using their critical-thinking and problem-solving skills to explore human impact on the blue crab ecosystem. The purpose of "Crabby Interactions" was to help students understand the impact of human activities on the local…

Of the eight scientific practices highlighted in "A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas," the first is for students to develop abilities to ask questions and define problems (NRC 2012). Constructing a range of questions about an object or phenomenon validates not only what students have…

Where the author teaches is far from the ocean, bordered on one side by forests of ponderosa and by the High Desert on the other. So when his first graders walked into class on the Monday morning after the 2011 earthquake and subsequent tsunami along the coast of Japan--and their usual light conversations about the weekend included some sobering…

Children's descriptions of commonplace objects and events of life are often limited because they do not provide adequate information about the context of their observation. Encouraging primary and early intermediate students to consider the context of an observation can further encourage them to generate questions about what they are observing and…

Physical models in the classroom "cannot be expected to represent the full-scale phenomenon with complete accuracy, not even in the limited set of characteristics being studied" (AAAS 1990). Therefore, by modifying a popular classroom activity called a "planet walk," teachers can explore upper elementary students' current understandings; create an…

A prop box is a teacher-created resource full of age-appropriate and meaningful activities focused on a central theme. Prop boxes work much like learning centers in an elementary classroom with the important addition of providing opportunities for socio-dramatic play. Prop box play engages students in self-chosen activities that promote critical…

Presents a strategy for science learning through a game activity which uses human and/or animal footprints. Provides numerous ideas for creativity in constructing a story and adapting tracks for experiential experiences. (RT)
