Improving youth science comprehension in the United States is imperative to reverse current trends in student achievement and to meet an expected shortage of scientists in the future. This lag in achievement scores and need for future scientists is a problem. One challenge is to link inquiry-based learning and experiential education with curriculum designed to improve understanding, skill development, and reasoning abilities to achieve the broader impacts of improved science comprehension. The authors propose a conceptual process model for delivering Extension programs designed to enhance youth achievement in the sciences.
