Fishbone diagrams, also known as Ishikawa diagrams or cause-and-effect diagrams, are one of the many problem-solving tools created by Dr. Kaoru Ishikawa, a University of Tokyo professor. Part of the brilliance of Ishikawa's idea resides in the simplicity and practicality of the diagram's basic model--a fish's skeleton. This article describes how…

Mendel and his peas. Goodall and her chimpanzees. Bentley and his snowflakes. Pasteur and his sheep. Not only do these stories intrigue students, but they also demonstrate the trials and tribulations associated with scientific inquiry. Using scientists' biographies piques student interest while providing an added dimension to their understanding…

Through a project funded by the National Science Foundation, Horizon Research has been developing assessment items for students (in the process, compiling item-writing principles from several sources and adding their own). In this article, the authors share what they have learned about writing items that reveal student understanding, including…

To confront some of the challenges faced by teachers beginning to implement Standards-based inquiry activities in their middle school classrooms, learning coordinators and teachers selected an inquiry-based set of courses and created a District Science Curricula Scope and Sequence, which overviewed the major units and showed teachers and parents…

In this article, the author shares a very successful 50-minute inquiry-based physics lesson that uses only small metal cans, a bit of string, and the inquiring minds of middle schoolers. The topic of the lesson is wave motion and energy transfer. The intent of this article is to show that tests of student-generated hypotheses can be simple, quick,…

Teaching science in middle school is both rewarding and demanding. Creating an exciting learning environment with a rich science curriculum that engages all students is challenging enough. Monitoring the progress of as many as 150 individual students and knowing that they understand the science concepts we are teaching can be overwhelming. How can…
