Academic Engagement and Achievement Among Latina/o and Non-Latina/o Adolescents

This article presents an exploratory study of the relation between academic engagement and academic achievement for Latina/o and non-Latina/o adolescents attending a predominantly low-income, Latina/o urban middle school in Southern California. A sample of 61 students (37 Latinas/os and 24 non-Latinas/os) participated in the study. The Latina/o students’ mean grade point average was lower than the non-Latina/o students’ mean grade point average. The study results revealed a significant interaction between academic engagement and grade point average for Latina/o students but not for non-Latina/o students. Findings are discussed in regard to the promotion of Latina/o adolescent achievement through increased levels of academic engagement.     

Accountability,school reform,and equity: The troubling case of Sylvan school district

Most educational accountability systems draw upon relatively simplified indicators of student learning. Despite sufficient criticism and evidence of their misuse, test scores continue to be emphasized—even though they have a deadening effect on the very school district these accountability systems intend to primarily influence. This paper focuses on one of these low-performing school districts. The case study of Sylvan One reveals that the influence of state policy is especially circumscribed in a district like Sylvan's that is beset by such prevailing conditions as the politics of race, the culture of poverty, vacuums in communication and leadership, and the uncritical mass of human resources. Each of these conditions limits change and reform dramatically. Account-ability and reform must focus on a rigorous curriculum and well-understood standards—but only in the context of this community, replete with its problems ofrelationships, resources, andracism. These are the “three Rs” that are tantamount to creating and sustaining reform. And this approach is more about political development than anything else. Recommendations for moving beyond the traditional policymaking tools of mandates and inducements are suggested, recognizing that policy may at best promote equality, but not necessarily excellence and equity.     

Required pecking and refraining from pecking alter judgments of time by pigeons

There is evidence that humans' perception of time is affected by the activity in which they are engaged while they are timing. The more demanding the task, the faster time appears to pass. A similar effect has been found in pigeons. Pigeons trained to discriminate between a short-duration (2-sec) and a long-duration (10-sec) stimulus were required to peck when the stimulus was one color and to refrain from pecking when it was a different color. On probe trials of intermediate durations, the bisection point (50% choice of the stimulus associated with both long and short stimuli) for trials in which the pigeons were required to peck was almost 1 sec longer than on trials in which the pigeons were required to refrain from pecking (Zentall, Friedrich, & Clement, 2006). In the present research, we replicated this effect and determined the relation between this effect and the typical bisection point that occurs when pecking is permitted but not required. Results indicated that the typical procedure results in a bisection point that is between required pecking and refraining from pecking. Furthermore, the rate of pecking when pecking is allowed but not required also falls between the rate of pecking for the required-pecking and refrain-from-pecking conditions. This result suggests that, similar to humans, pigeons underestimate the passage of time when they are active or when attention to time-related cues has to be shared with attention to satisfying the response requirement.
