Technology is changing the way students interact with knowledge, and open-ended activities are one of the main types of tasks that students engage with in technology-rich environments. However, the amount of guidance needed to promote learning in these environments remains unknown. We explore this issue by focusing on the effects of step-by-step…

This dissertation explored the roles schools can play in the successful outcomes of large carnivore or keystone reintroduction projects. Schools are more than centers for knowledge acquisition--they connect their community and disseminate information quickly to a wide audience. This study took place in California's Eastern Sierra Nevada, a…

As California competes for jobs in an increasingly competitive global economy, the state faces a looming shortage of highly educated workers (PPIC, 2012). For a variety of reasons, the need for individuals with degrees in science, technology, engineering, and mathematics (STEM) is of particular concern. Nowhere is this more true than in the…

Although studies examining student understanding of key concepts are common throughout the science education literature, few have examined science concepts linked to conservation or environmental issues such as global warming and alternative energy. How students make sense of these complex concepts has the potential to influence their role as…

This study reports on our steps toward achieving a conceptually coherent and empirically validated learning progression for carbon cycling in socio-ecological systems. It describes an iterative process of designing and analyzing assessment and interview data from students in upper elementary through high school. The product of our development…

The study reported here investigated the impacts of participation in 4-H on young people's interest and participation in science. Survey data were collected from relatively large and ethnically diverse samples of elementary and high school-aged students in California. Results indicated that although elementary-grade 4-H members are not more…

Given California's role in the Pacific economy, its historic Asian heritage, and the strong and growing presence of Asian communities and businesses in the state, it is imperative that students statewide understand the history of Asia. Unfortunately, the California state curricular framework and standards in history and social science limit the…

This article reports on a public school that is succeeding in encouraging Latino high school students to select Computer Science (CS) as a major. The students attend a charter high school designed to encourage low-income Latino students to attend college and attain proficiency in English, Spanish, and computers. Using data from surveys and by…

This paper describes how a university outreach program promotes academic achievement and identity development among culturally diverse tenth-grade students. The primary goal of the outreach program is to advance students' engagement and competency in mathematics and science learning. A secondary goal of the program is to promote the development of…
