The vision for science proficiency presented in "A Framework for K-12 Science Education" calls for significant shifts in both teaching and assessment. In this paper, we describe an effort to develop and validate a set of "proximal transfer tasks" for high school biology classrooms where teachers were implementing a…

Problem-based learning (PBL) is widely endorsed as a desirable learning method, particularly in science. Especially in light of the method's heavy demand on resources, evidence-based practice is called for. Rigorous studies of the method's effectiveness, however, are scarce. In Study 1, college students enrolled in an elementary physics course…

This case study involved year 9 students carrying out project work in biology via problem-based learning. The purpose of the study was to (a) find out how students approach and work through ill-structured problems, (b) identify some issues and challenges related to the use of such problems, and (c) offer some practical suggestions on the…

Describes the development of a project-based unit on hot-air balloons used with Israeli junior high school students. Concludes that students in the program gained experience with high-level scientific principles and technological processes, the project allows for a learning environment of cooperation and teamwork, and collaboration between…
