Laboratory experiences as a part of most U.S. high school science curricula have been taken for granted for decades, but they have rarely been carefully examined. What do they contribute to science learning? What can they contribute to science learning? What is the current status of labs in our nation�s high schools as a context for learning science? This book looks at a range of questions about how laboratory experiences fit into U.S. high schools: What is effective laboratory teaching? What does research tell us about learning in high school science labs? How should student learning in laboratory experiences be assessed? Do all student have access to laboratory experiences? What changes need to be made to improve laboratory experiences for high school students? How can school organization contribute to effective laboratory teaching? With increased attention to the U.S. education system and student outcomes, no part of the high school curriculum should escape scrutiny. This timely book investigates factors that influence a high school laboratory experience, looking closely at what currently takes place and what the goals of those experiences are and should be. Science educators, school administrators, policy makers, and parents will all benefit from a better understanding of the need for laboratory experiences to be an integral part of the science curriculum-and how that can be accomplished.
Many would argue that the state of urban science education has been static for the past several decades and that there is little to learn from it. Rather than accepting this deficit perspective, Improving Urban Science Education strives to recognize and understand the successes that exist there by systematically documenting seven years of research into issues salient to teaching and learning in urban high school science classes. Grounded in the post structuralism of William Sewell_and brought to life through the experiences of different students, teachers, and school settings in Philadelphia_this book shows how teachers and students can work together to enact meaningful science education when social and cultural differences as well as inappropriate curricula often make the challenges seem insurmountable. Chapters contain rich images of urban youth and each strives to offer insights into problems and suggestions for resolving them. Most significant, in spite of the challenges, the research offers hope and shows that fresh approaches to teaching and learning can lead students_some who have already been pronounced academic, even societal, failures_to becoming avid and deep learners of science.
