Since August of 2011, Project iLASER (Investigations with Light And Sustainable Energy Resources) has engaged children, youth and adults in public science education and hands-on activities across the entire length of the U.S.-Mexico border, from the Pacific Ocean to the Gulf of Mexico. The two main themes of Project iLASER activities focus on sustainable energy and materials science. More than 1,000 children have been engaged in the hands-on activities developed through Project iLASER at 20+ sites, primarily in after-school settings in Boys & Girls Clubs. Sites include Boys & Girls Clubs in California (Chula Vista, Imperial Beach, El Centro and Brawley); Arizona (Nogales); New Mexico (Las Cruces); and Texas (El Paso, Midland-Odessa, Edinburg and Corpus Christi). The project was co-funded between the NSF Division of Chemistry (CHE) and the Division of Research on Learning in Formal and Informal Settings (DRL).

The University of Texas at El Paso will conduct a research project that implements and documents the impact of co-generative dialogues on youth learning and youth-scientist interactions as part of a STEM research program (i.e., Work with A Scientist Program). Co-generative dialogues seek to specifically assist with communication and understanding among collaborators. Over four years, 108 11th grade youth from a predominantly (90%) Hispanic high school will conduct STEM research with twelve scientists/engineers (e.g., chemist, civil engineer, geologist, biologist) and undergraduate/graduate students as part of 7 month-long after school program, including bi-weekly Saturday activities for 5 months followed by an intensive month-long, self-directed research project in the summer. Youth will be randomly assigned to experimental groups that include the co-generative dialogue treatment and control groups without the intervention. The scientists and their STEM undergraduate/graduate students will participate in both experimental and control groups, with different youth. Youth will receive high school credit to encourage participation and retention. The PI team hypothesizes that co-generative dialogues will result in improved learning, communication, and research experiences for both youth and scientists. Educational researchers will conduct co-generative dialogues, observations, interviews, and surveys using validated instruments to address the following research goals: (1) To investigate the impact of the treatment (co-generative dialogues) on youth knowledge, attitudes, perceptions of their experience, and their relationships with the scientists; (2) To investigate the impact of the treatment on scientists and graduate students; and (3) To identify critical components of the treatment that affect youth-scientist interactions. It is anticipated that, in addition to providing in-depth STEM research experiences for 108 youth from underrepresented groups at a critical time in their lives, the project will result in widely applicable understandings of how pedagogical approaches affect both youth learning and scientist experiences. The project also seeks to bridge learning environments: informal, formal, university and digital.
The proposed CAREER study uses a comprehensive mixed-methods design to develop measures of motivational beliefs and family supports for Spanish and English speaking Mexican-origin youth in high school physical science. The research examines a three-part model which may provide a deeper understanding of how Mexican families support youth through their general education strategies, beliefs about physical science, and science specific behaviors. This approach incorporates motivation and ecodevelopmental theories while pursuing an innovative line of research that examines how the contributions of older siblings and relatives complement or supplement parental support. The study has four aims which are to (1) to develop reliable, valid measures of Mexican-origin adolescent motivational beliefs and family supports in relation to high school chemistry and physics, (2) to test whether family supports predict motivational beliefs and course enrollment, (3) to test how indicators in Aim 2 vary based on gender, culture, English language skills and relationship quality, and (4) to examine how family supports strengthen or weaken the relationship between school-based interactions (teachers and peer support) and the pursuit of physical science studies. Spanish and English-speaking Mexican-origin youth will participate in focus groups to inform the development of a survey instrument which will be used in a statistical measurement equivalence study of 300 high school students in fulfillment of Aim 1. One hundred and fifty Mexican high school students and their families will participate in a longitudinal study while students progress through grades 9-12 to examine Aims 2- 4. Data to be collected includes information on science coursework, adolescent motivational beliefs, supports by mothers and older youth in the family, and family interactions. All materials will be in English and Spanish. The educational and research integration plan uses a three pronged approach which includes mentoring of doctoral students, teacher outreach, and the evaluation of the ASU Biodesign high school summer internship program using measures resulting from the research. It is anticipated that the study findings will provide research-based solutions to some of the specific behaviors that influence youth motivation in physical sciences. Specifically, the study will identify youth that might be most affected by an intervention and the age of maximum benefit, as well as valid, reliable measures of youths' motivation that can used in interventions to measure outcomes. The study will also identify family behaviors that may be influenced, including education strategies for school preparation, beliefs about physical science, and sciece-specific strategies such as engaging in science activities outside school. The findings will be broadly disseminated to science teachers, scholars, and families of Mexican-origin youth. This multi-tiered approach will advance current scholarship and practice concerning Mexican-origin adolescents' pursuit of physical science.
Individuals are at an increased risk to drop out of the STEM pipeline if they are female or Latino, and during certain periods including high school. Families are a potential untapped resource of support for high school students. Based on the expectancy-value model, we examined if a variety of parental behaviors predicted students’ ability self-concepts in and value they placed on biology, chemistry, and physics. Self-report surveys were collected from 988 9th grade Latino boys, Latina girls, Caucasian boys, and Caucasian girls. The findings suggest that, as early as the beginning of high
