According to the 2014–2015 State of the States in Gifted Education, Colorado is the only state in the United States where a series of on-site, customized twice-exceptional professional development (2E PD) opportunities have been implemented. The purpose of this case study evaluation was to understand the implementation of 2E PD during 2014–2016 in a school district in Colorado. Seven training participants and four administrators who were involved in the training were purposefully selected. Data sources consisted of interviews, documentation, and archival records. Eight major themes emerged: (a) increased knowledge and skills, (b) evolved attitudes, (c) recurring challenges, (d) utilizing a team approach, (e) improved performance, (f) difficulty in measuring impact, (g) improved school culture, and (h) planning for the future. In addition to a discussion of themes, implications for improving educator and student outcomes and for creating organizational support and changes are presented.

In this paper, we propose an extended chaotic maps-based keyword search scheme over encrypted data resist outside and inside keyword guessing attacks in cloud storage services, which achieves the essential requirements of a secure cloud storage service. A secure cloud storage service has to satisfy five security requirements: consistency, ciphertext indistinguishability, trapdoor indistinguishability and resist off-line keyword guessing attacks (including offline outside keyword guessing attack and off-line inside keyword guessing attack). Moreover, due to the characteristics of extended chaotic maps and session key establishment, which allow two communication parties to agree a common session key and the agreed session key is only known by the data sender and the authorized data receiver. Therefore, in this paper, we integrated the concept of session key establishment and extended chaotic maps into our proposed scheme which aims to resist the off-line keyword guessing attacks not only from the outside cloud attackers but also from an inside malicious cloud server. To the best of our knowledge, none of the recently proposed secure keyword search schemes can resist inside keyword guessing attacks and this work is the first attempt to provide a secure keyword search scheme without inside keyword guessing attacks in cloud storage services.

This column presents the 2019 NAGC Pre-K to Grade 12 Gifted Programming Standards and its applications to the field of gifted education. It describes the revision process and the differences between the 2010 NAGC Programming Standards and this revision. These differences include the incorporation of new research, evidence, and best practices; alignments with other national professional standards; and an emphasis on shared terminology across various fields, simplified language, and streamlined outcomes and evidence-based practices.
