A CHASE domain containing protein kinase OsCRL4,represents a new AtCRE1-like gene family in rice

INTRODUCTION Cytokinins play a major role in many differentdevelopmental and physiological plant processes,such as cell division, regulation of root and shootgrowth and branching, chloroplast development,leaf senescence, stress response and pathogen re-sistance (Mok and Mok, 2001). Significant ad-vances have been achieved in our understanding ofcytokinin signaling, providing important insightsinto the molecular partners involved (Hutchisonand Kieber, 2002; Sheen, 2002). It had been…

A theory of instruction for introductory programming skills

ABSTRACT

Background and Context: Current introductory instruction fails to identify, structure, and sequence the many skills involved in programming.

Objective: We proposed a theory which identifies four distinct skills that novices learn incrementally. These skills are tracing, writing syntax, comprehending templates (reusable abstractions of programming knowledge), and writing code with templates. We theorized that explicit instruction of these skills decreases cognitive demand.

Method: We conducted an exploratory mixed-methods study and compared students’ exercise completion rates, error rates, ability to explain code, and engagement when learning to program. We compared material that reflects this theory to more traditional material that does not distinguish between skills.

Findings: Teaching skills incrementally resulted in improved completion rate on practice exercises, and decreased error rate and improved understanding of the post-test.

Implications: By structuring programming skills such that they can be taught explicitly and incrementally, we can inform instructional design and improve future research on understanding how novice programmers develop understanding.     

Contemporary Classics? The Early Onset of Influence of Articles Published in Criminology and Criminal Justice Journals, 2010–2015

Citation analysis is a valuable method for tracking the growth and transmission of scientific knowledge. In criminology and criminal justice, such analyses tend to be focused on “classic” works or on highly cited scholars over many years. As an alternative approach, we focus on work that has been cited rather quickly – what we term the “early onset” of impact. In doing so, we identified 221 of the most highly cited peer-reviewed articles, authored by 480 scholars, which were published in criminology and criminal justice journals between 2010 and 2015. Analyses reveal wide variation in substantive topics and methodological approaches, as well as a substantial gender gap with respect to authorship. Additional analyses provide insight into both journal and institutional/program prestige. We conclude with directions for future research and stress the importance of tracking over time articles that appear to be off to an early start with respect to scholarly impact.

Introduction to “Racial Inequality and Education: Patterns and Prospects for the Future”

Abstract

American society is in the midst of profound economic and demographic changes. At the same time that the racial and ethnic composition of American society is changing, disparities in income and wealth have grown wider and more pronounced than ever before. This article explores the ways in which race is implicated in the widening gaps in wealth and opportunity, and how these inequities impact educational achievement.
