In this paper, we report findings from the second year of a threeyear research and professional development program designed to help elementary school teachers engage in dialogic teaching to support the development of students' argument literacy. We define argument literacy as the ability to comprehend and formulate arguments through speaking, listening, reading, and writing. The professional development program was focused on promoting teachers' use of a specific type of talk called 'inquiry dialogue' to achieve the goal of developing students' argument literacy. We used a single-group pretest-posttest design to assess the impact of the professional development on teachers' epistemological beliefs and their enactment of inquiry dialogue in text-based discussions. Our analyses of videotaped discussions at the beginning and end of the year showed that there were substantial improvements in teachers' facilitation of inquiry dialogue and in the quality of students' argumentation during discussions. Contrary to expectations, however, there were no changes in teachers' epistemology; teachers' beliefs about knowledge and knowledge justification remained at a relativist stage throughout the course of the program, suggesting that teachers continued to view all opinions as equally valid and regard arguments and the use of reasons and evidence as idiosyncratic.

This study investigates how adolescents begin to demonstrate skills and approaches that help them pursue their aspirations. The qualitative study examined emergent forms of key indicators of adolescent thriving: the 5Cs of positive youth development and sense of purpose. Pre- and post-program interviews with 24 S2 (~seventh grade) Scottish adolescents who participated in a school-based character program explored the presence, absence, and elucidations of each of the 5Cs as well as their conceptualizations of a sense of purpose. Findings showed great variability within the sample, despite participants’ similarities in age, race, ethnicity, and socioeconomic status. This work informs future study and measurement of potentially nascent forms of the 5Cs and purpose among early adolescents.
