This study examined the various ways adults engage and support youth in connected learning settings, which are focused on supporting youth in their interests or passions. Youth from 5 Chicago community-based, out-of-school time (OST) programs participated in focus groups on the topic of adult-youth relationships. Participants reported characteristics and behaviors of supportive adults as well as the outcomes associated with those behaviors. Analyses revealed that the following characteristics of adults enabled engagement and relationship development: (a) mutual respect, (b) genuine interest, (c) ongoing communication and friendship, and (d) going above and beyond. Youth also identified the specific ways that adults supported them: (a) guidance and motivation, (b) skill-based support, (c) role modeling, (d) connecting, (e) emotional support, and (f) cultivating youth voice. Finally, participants reported the following outcomes related to such support: (a) social capital, (b) a sense of empowerment and control of their futures, and (c) a sense of acceptance and validation. This study is a contribution to the literature on adult-youth relationships in connected learning sites and draws attention to the potential socioemotional and instructional benefits of such programs. Our study also highlights the various ways that adults in OST programs can successfully engage youth and form relationships.Most recently, researchers have become interested in youth sparks and interests because of their developmental benefits. Sparks are a "passion for a self-identified interest, skill or capacity that metaphorically lights a fire in the adolescent's life, providing energy, joy, purpose and direction" (Scales, Benson, & Roehlkepartain, 2011, p. 264). A national study of racially/ethnically diverse 15-year-olds found that participants in the high sparks group had better academic outcomes (i.e., more focused on learning, higher grades, more effort in school) than youth in the low sparks or no sparks J.

For instance, in their sample of African American adolescents, Hurd and Sellers (2013) found that more connected (e.g., closer, more involved) mentoring relationships yielded greater academic engagement compared to not having mentoring relationships at all. Liao and Sanchez (2016) also found that urban, low-income Latinx adolescents with closer and more growth-oriented relationships (e.g., higher relational quality and instrumental quality) had better academic outcomes compared to those with less close and less growth-oriented relationships or those without mentors. Hence, the youth mentoring literature suggests the importance of focusing on the quality of youth-adult relationships. Similar to research on mentoring, investigations of OST and conne...
