ConstraintsThe researchers experienced a variety of constraints while working within the public school setting. The demands of high-stakes testing made the teaching of the science curriculum secondary to the teaching of math, reading, and writing. The researchers were therefore provided with a maximum of 45 minutes per day for a two-week period to conduct the study. Integration of science with other areas of the curriculum was also not a possibility in this time frame, nor was it feasible to work with ESL teachers and special educators to more adequately meet the needs of students with limited English proficiency or students with significant learning difficulties.
