Evaluating the Influence of an Urban High School Reform Effort on College Readiness and Access Outcomes: A Quasiexperimental Cohort Study

It is widely accepted that postsecondary education has become a necessity for US youth. College access, however, has been found not to be equal for all. As a result, federally funded college-readiness programs, such as Gaining Early Awareness and Readiness for Undergraduate Programs (GEAR UP), have been established to increase the numbers of economically disadvantaged students with access to college. This quasiexperimental case study compared academic and nonacademic college-readiness indicators between cohorts of GEAR UP students and nonparticipants in 1 urban high school. Overall, cohorts of GEAR UP students outperformed their non-GEAR UP peers on all measures (grade-point average, attendance rate, behavior, graduation rate, and college enrollment) despite a dramatic demographic shift that led to greater proportions of educationally disadvantaged students in the GEAR UP cohorts.     

Reading to Children and Listening to Children Read: Mother–Child Interactions as a Function of Principal Reader

Research Findings: Although storybook reading has received considerable research attention, listening to children read has been the source of much less inquiry. In this study, 40 mother–child dyads were videotaped during adult-to-child and child-to-adult reading. Relations between book-related themes (e.g., types of talk), maternal evaluative feedback (e.g., praise, criticism), maternal miscue feedback (e.g., graphophonemic clues, terminal feedback), and child engagement (e.g., laughter, questions) were analyzed. The results suggest that the development of literacy appreciation and literacy skill can occur during the same storybook-reading session. Specifically, when mothers read to their children, communication about the illustrations was associated with increased child engagement, yet a positive correlation was also observed between text-related productions and child engagement. When children read to their mothers, text-related productions were featured more prominently. After children made reading errors (miscues), graphophonemic and terminal feedback were the 2 most frequent responses by mothers. In addition, graphophonemic cues were positively associated with child engagement. Practice or Policy: In sum, the results demonstrate that adult-to-child and child-to-adult reading serve the goals of both literacy acquisition training and literacy appreciation; furthermore, orienting children toward the text during either session did not hamper child engagement.     

Developing sociopolitical consciousness at Freedom Schools: implications for culturally responsive teacher preparation

This article describes the programmatic ways in which the Children’s Defense Fund Freedom Schools® program develops culturally responsive teaching practices?amongst its summer interns, particularly in the area of developing sociopolitical consciousness.?This paper places specific focus on the role that historical knowledge, the acknowledgement of a ‘we’ discourse and instilling a lifelong commitment to service plays in cultivating teacher sociopolitical consciousness. The research reported here aims to serve as a case for lessons to be learned by traditional, university-based teacher education programs committed to preparing teachers to teach in culturally responsive ways.     

Teaching gender and sexuality diversity in foundations of education courses in the US

This article is a summary of comprehensive units on gender and sexuality diversity that the authors have used in teacher education courses in undergraduate and graduate social foundations of education classes over several years. The course lesson plan includes a five‐part analysis of the following categories: biological sex; gender identity/sexual identity; gender roles; sexual behavior; and sexual orientation. The authors have experienced much success and positive student evaluation by using this approach. This is true even in religiously and politically conservative universities. The authors introduce the complexity of biology, gender roles, and gender identity, before addressing human sexuality. This helps to diffuse many stereotypes and misconceptions in the initial lessons.     

How to combine objectives and methods of evaluation in iterative ILE design: lessons learned from designing Ambre-add

This article deals with evaluating an interactive learning environment (ILE) during the iterative-design process. Various aspects of the system must be assessed and a number of evaluation methods are available. In designing the ILE Ambre-add, several techniques were combined to test and refine the system. In particular, we point out the merits of combining measures of the ILE's impact on learning with analyses of the learner's activity. In this article, the approach used to evaluate Ambre-add is described and analyzed, and its advantages and disadvantages are discussed. Then, a general procedure for evaluating ILEs during iterative design is proposed.     

Classroom behaviour management content in Australian undergraduate primary teaching programmes

The ability to differentiate classroom behaviour management (CBM) strategies is an important skill for novice teachers in increasingly diverse classrooms. Worldwide, little is known about the curriculum content offered to pre-service teachers in the area of CBM. This article reports the findings from the first nationwide survey of Australian primary pre-service teacher educators coordinating units and programmes with CBM content. Twenty-five Australian tertiary institutions with primary programmes participated, providing information on 102 of the 118 units with CBM content. Stand-alone units were offered in 68% of programmes and embedded in 96% of programmes. Unit coordinators included a mean of 8.3 approaches/models per unit. They commonly included applied behaviour analysis, decisive discipline, positive behaviour intervention and support, and choice theory/reality therapy, among the 36 approaches/models listed. More than half (57.9%) of the stand-alone units and only 20% of embedded units were coordinated by an academic with a stated CBM research interests. Units coordinated by an academic with CBM research interests contained more hours/model and included research-based models more often than those without CBM research interests, although they still included non-research-based models.

Stability of switching linear systems with switching signals driven by stochastic processes

This paper presents conditions to assure the exponential stability in probability for autonomous switching linear systems. The switching signal acting on the autonomous system produces intervals that follow independent, identically distributed stochastic processes—the stability then follows by verifying simple-to-check linear matrix inequalities.     

Distributed optimization with information-constrained population dynamics

In a multi-agent framework, distributed optimization problems are generally described as the minimization of a global objective function, where each agent can get information only from a neighborhood defined by a network topology. To solve the problem, this work presents an information-constrained strategy based on population dynamics, where payoff functions and tasks are assigned to each node in a connected graph. We prove that the so-called distributed replicator equation (DRE) converges to an optimal global outcome by means of the local-information exchange subject to the topological constraints of the graph. To show the application of the proposed strategy, we implement the DRE to solve an economic dispatch problem with distributed generation. We also present some simulation results to illustrate the theoretic optimality and stability of the equilibrium points and the effects of typical network topologies on the convergence rate of the algorithm.
