Will Obama's My Brother's Keeper and Similar Initiatives Have a Positive Impact on Low-Income Students?

Barack Obama's My Brother's Keeper is designed to narrow persistent gaps that boys and young men of color confront often and to help all young people achieve their potential in college and career.

How do instructional designers evaluate? A qualitative study of evaluation in practice

This study employed a qualitative research design to investigate how instructional designers use evaluation in everyday design practice. While past research has examined how designers spend their time, how they generally make decisions, and expert-novice differences, little attention has been paid to use of context, input, process, or product evaluation, from the perspective of practicing designers. Based on interviews of practitioners, our findings included ten themes regarding how designers use evaluation to improve their products. While these results substantiate to some degree the claim that practitioners believe clients will not pay for formal evaluations, they also suggest that practitioners use evaluation in important but less formal ways. Other conclusions regarding the role of evaluation in design are provided and future directions for training and research are discussed.     

Creating Collaborative Partnership With Local Churches to Improve Academic Performance of K-12 Public Schools

Since their founding, the Black churches have strived to implement and fulfill their missions. These institutions acknowledge the importance to become actively involved in the community as well as engaged in the lives of young people. Black churches are faced with unique challenges every day, however, they provide significant number of resources to the communities at large. In this study, we examine the role of partnerships through local churches and its impact on low performing schools using qualitative methodology. Research shows that low performing schools are influenced positively by partnerships with Black churches.
