Peer-Collaborator Preferences of African American and White Sixth-Graders in Mathematics Classrooms

Abstract

This study focused on academic and social correlates of collaborator preferences of African American and White sixth-graders in mathematics classrooms in fall and spring. Students’ appraisals of emotional risk were examined as a moderator. Nomination procedures identified collaborator preferences, group affiliations, and social centrality; students self-reported engagement and emotional risk; school records provided achievement scores. Results indicated students preferred group affiliates, but not exclusively, as collaborators. Students with greater centrality, achievement, and engagement received more nominations. In the fall, high achievers received more nominations when appraisals of risk were high; whereas, engaged students whose appraisals of risk were low received more nominations. Results are interpreted in relation to coordinating social and academic factors in peer collaboration.

Evaluating a computer‐based reading programme with children with Intellectual Disabilities: feasibility and pilot research

Increasing evidence indicates that individuals with Intellectual Disabilities (ID) might benefit from phonics‐based reading instruction. However, research and instruction in this field has predominantly focused on sight word reading. Models for complex interventions recommend that feasibility research be conducted prior to conducting randomised studies to assess efficacy of interventions (Thabane et al., 2010). The aim of the current paper is therefore to investigate feasibility questions relating to conducting a full‐scale randomised controlled trial (RCT) evaluation of an online, phonics‐based reading programme (Headsprout^? Early Reading; HER) with children with ID. Employing a randomised pre‐test post‐test group design, this study explores and trials important aspects of a RCT evaluation to inform a full‐scale RCT. We also found that HER had a significant effect on reading skills when compared with ‘education as usual’, with large effect sizes on the main outcome measure. This indicates that further, more robust evaluations using HER with children with ID are a worthwhile pursuit.     

大学英语中个性化教学的探索与实践

个性化教学不是一种学习方式或方法,而是一种教育理念。在每个学生接受传授的同时,以学生为中心,目的是让学生按自己的进度,用自己的方法来学习他们所需要的内容,计算机和网络技术是必要的硬件保证。文章探讨了使用计算机进行个性化教学的利与弊以及如何进行个性化教学。最后,作者以一次教学尝试说明了个性化教学的可行性和效果。

论科学知识观的转型及其对科学教学的意义

科学知识观是科学教学的前提与先导.科学知识观主要包括对科学知识的性质和获得两个方面的认识.科学知识的性质在原来传统的、确定的、客观的、普遍的、价值中立的基础上增加了不确定性、文化性、境域性、价值性等因素,科学知识的获得已由主观认识与客观对象相符合的过程,向开放、动态、生成的过程转变.科学教师树立现代科学知识观,有利于调...     

教学临界阈研究的问题与思路

教学临界阈研究是探究和揭示教学有效性内在本质及其规律的关键,是我们对有效教学问题从外条件研究到内问题探讨的转折点。这些内问题的探讨主要包括学习者的有效学习量究竟是多少才能引起学习临界点的出现,影响教学从量变到质变的关键因素是什么,教学临界阈的产生能否促使学习者知而达智、行而致能。超额学习、掌握学习、语言输入理论、结构方程模式等成果为教学临界阈的研究奠定了基础,人类工效学、知识生态学和博弈论更是为教学临界阈研究提供了多元视角。时间、空间、群体和影响程度等质变临界阈的存在意味着教学临界阈研究有着不同的研究思路,而具体内容学习变化的曲线则是判断教学临界阈的基本依据。通过变量干预而改变教学临界状态是研究有效教学的一个新的切入点。     

德育在高职英语教学中的渗透

在高职英语教学过程中,教师应设法改变德育缺失的状况,借助教材的德育内涵、英语礼貌原则及良好的教学言语和行为,把德育潜移默化地贯穿到传授英语语言知识、培养学生英语语言能力和英语交际能力中,提高英语教学质量和德育效率,满足新形势对复合型人才的要求。
