Adolescence is a distinct, yet transient, period of development between childhood and adulthood characterized by increased experimentation and risk-taking, a tendency to discount long-term consequences, and heightened sensitivity to peers and other social influences. A key function of adolescence is developing an integrated sense of self, including individualization, separation from parents, and personal identity. Experimentation and novelty-seeking behavior, such as alcohol and drug use, unsafe sex, and reckless driving, are thought to serve a number of adaptive functions despite their risks. Research indicates that for most youth, the period of risky experimentation does not extend beyond adolescence, ceasing as identity becomes settled with maturity. Much adolescent involvement in criminal activity is part of the normal developmental process of identity formation and most adolescents will mature out of these tendencies.Evidence of significant changes in brain structure and function during adolescence strongly suggests that these cognitive tendencies characteristic of adolescents are associated with biological immaturity of the brain and with an imbalance among developing brain systems. This imbalance model implies dual systems: one involved in cognitive and behavioral control and one involved in socio-emotional processes. Accordingly adolescents lack mature capacity for self-regulations because the brain system that influences pleasure-seeking and emotional reactivity develops more rapidly than the brain system that supports self-control. This knowledge of adolescent development has underscored important differences between adults and adolescents with direct bearing on the design and operation of the justice system, raising doubts about the core assumptions driving the criminalization of juvenile justice policy in the late decades of the 20th century. It was in this context that the Office of Juvenile Justice and Delinquency Prevention (OJJDP) asked the National Research Council to convene a committee to conduct a study of juvenile justice reform.The goal of Reforming Juvenile Justice: A Developmental Approach was to review recent advances in behavioral and neuroscience research and draw out the implications of this knowledge for juvenile justice reform, to assess the new generation of reform activities occurring in the United States, and to assess the performance of OJJDP in carrying out its statutory mission as well as its potential role in supporting scientifically based reform efforts.

As student learning objectives become an increasingly prominent approach to setting goals and growth measures in schools, teachers’ competence in formative assessment is essential. Using Formative Assessment to Support Student Learning Objectives introduces current and future educators to SLOs as tools for shaping career- and college-ready students. Written in concise and straightforward language, and replete with step-by-step exercises, real-life examples, and illustrative charts, this useful guide provides pre- and in-service educators with the theoretical background and practical tools needed to implement the latest SLO research in their classrooms.

Synthesizing the literature from the survey and measurement fields, this book explains how to develop closed-response survey scales that will accurately capture such constructs as attitudes, beliefs, or behaviors. It provides guidelines to help applied researchers or graduate students review existing scales for possible adoption or adaptation in a study; create their own conceptual framework for a scale; write checklists, true-false variations, and Likert-style items; design response scales; examine validity and reliability; conduct a factor analysis; and document the instrument development and its technical quality. Advice is given on constructing tables and graphs to report survey scale results. Concepts and procedures are illustrated with "Not This/But This" examples from multiple disciplines.User-Friendly Features*End-of-chapter exercises with sample solutions, plus annotated suggestions for further reading.*"Not This/But This" examples of poorly written and strong survey items.*Chapter-opening overviews and within-chapter summaries.*Glossary of key concepts.*Appendix with examples of parametric and nonparametric procedures for group comparisons.

A comprehensive resource for assessment practitioners, this book provides step-by-step guidance for developing, administering, scoring, and validating a range of performance tasks, including literacy and other types of proficiency assessments. The authors explore how to establish the purpose of the assessment and how to develop scoring tools, train raters, reduce rater bias, review scores and report results, and use item-level and test-level analyses to optimize reliability and validity. Clearly written and well organized, the book includes many practical examples and accessible explanations of concepts and statistical procedures. It encompasses the breadth of applications of performance assessment today, from educational testing and the credentialing of professionals to research and program evaluation.User-friendly features include:*Checklists of activities to complete at each stage of a performance assessment *End-of-chapter questions to facilitate self-study *Annotated suggestions for further reading *A quick-reference glossary of terms*Examples drawn from multiple educational and professional licensure contexts
