Exploring threats to internal validity of direct assessment in single-case design research.

Single-case design research studies have historically used external observers to collect time series data that may be used to evaluate intervention effectiveness; however, single-case interventions implemented in educational settings may use the person implementing the intervention (e.g., teacher) to collect data in order to maximize feasibility.

Creating Compassion: Using Art for Empathy Learning with Urban Youth.

Social-emotional learning (SEL) curricula are being increasingly implemented with young children; however, access to comprehensive programs can be prohibitive for programs limited by finances, time, or other factors. This article describes an exploratory case study that investigates the use of creative activity in the direct promotion of empathy and indirect promotion of other social-emotional skills for early elementary children in an urban-based after-school setting. A novel curriculum, Creating Compassion, which combines art engagement with explicit behavioral instruction, serves as a promising avenue for social-emotional skill development, and has particular importance for children from low-income households.
