A problem-solving experiment is a learning activity that uses experimental design to solve an authentic problem. It combines two evidence-based teaching strategies: problem-based learning and inquiry-based learning. The use of problem-based learning and scientific inquiry as an effective pedagogical tool in the science classroom has been well…

How do scientists make inferences for something they cannot directly observe? The Black Box approach seems ideal to help students understand how scientists work. Black Boxes are sealed units; their interior is not accessible. The effort to determine their possible content (internal structure) demands successive modifications in hypothesis,…

The Idea Bank provides tips and techniques for creative teaching, in about 1,000 words. For this article, the authors analyzed 93 educational applications (apps) that have the potential to help students meaningfully engage in the science practices outlined in the Next Generation Science Standards. Some of the ways teachers can use these apps in…

In looking at successful inquiry activities, patterns in pedagogical approach emerge (Meyer et al. 2011). This article discusses one such approach--the design challenge. A design challenge can be defined as an activity in which students are given an explicit task to create a product that meets a defined goal. However, simply asking students to…

Problem solving is a valuable skill in the science classroom. Students often use a variety of inquiry strategies to identify problems and their implications; develop action plans; locate relevant sources, information, and data; and formulate solutions. Problem solving is a logical, analytical, and sometimes creative process. The less tangible,…

The author presents the science and engineering practices from the recently released "A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas." He recognizes the changes implied by the new framework, and eventually a new generation of science education standards will present new perspectives for the science…

Too often, teachers scratch their heads and ask, "What were my students thinking?" then answer, "I don't want to know." But teachers should want to know, and students should question their own thinking, as well. Critical thinking involves not just problem solving, creativity, analysis, and synthesis but also self-awareness of learning and learning…

There are many types of inquiry activities out there: Demonstrations, guided or scaffolded inquiry labs, open- or free-inquiry labs, and problem-based or project-based learning activities are all staples in science education. The importance of inquiry is highlighted in such documents as the National Science Education Standards (NRC 1996) and the…

Whole-class inquiry (WCI) assessments range from challenging, paper-and-pencil puzzles to lab-based problems that require students to apply their own gathered data to a new scenario; the latter might also require students to perform a lab with new parameters, or to answer a question using data from a previous lab. In this article, the authors…

Teacher research--often called "action research"--is an intentional and systematic inquiry into one's own classroom practice with the goal of improved student learning (Cochran-Smith and Lytle 1993). In this article, the authors present a teacher research project undertaken to improve student understanding of the gas laws in a high…

Describes an activity on density and its role on an object's floating or sinking. Uses canned regular and diet Coke soda pop to demonstrate differences in density. (YDS)

Introduces the Global Positioning System (GPS) and explains its use in the science classroom. (YDS)

Focuses on problem-based learning (PBL). Explains ill-defined problems of PBL and compares PBL with the typical problem solving approach. Lists 10 steps to involve students in constructing understanding for use with PBL. (YDS)

Uses a hypothetical ecology problem in which students need to apply problem based learning for a town government. Explains how to evaluate student results. (YDS)

Describes the stages and outcomes of a junior high school science lesson on erosion and deposition utilizing a "kids as researchers" theme. Stages include awareness, discussion, investigation, experimentation, generalization, and extension. (SK)
