Special education and general education preservice teachers’ co-teaching experiences: a comparative synthesis of qualitative research

Co-teaching is commonly used to support students with disabilities in inclusive educational settings. However, there is often a gap between the potential effectiveness of co-teaching and actual classroom practice. This study examined preservice teachers’ co-teaching experiences to better understand this gap to identify potential practices for improving teacher training and service delivery. A review of 11 studies revealed that both special education and general education preservice teachers believed that co-teaching practices provided them opportunities to communicate and work collaboratively. Both groups agreed on the significant impact of personality in co-teaching as well as challenges in implementing co-teaching. Furthermore, special education preservice teachers noted that they lacked content knowledge, whereas general education preservice teachers thought they needed more training in the provision of accommodations and modifications. Study limitations, areas for future research, and implications for preservice teacher preparation are discussed.

Hearing Words,Learning Words: How Different Presentations of Novel Vocabulary Words Affect Children’s Incidental Learning

Research Findings: Children learn most of their vocabulary incidentally, by hearing words used in their environment. This study explored which kinds of presentations of words, without any direct instruction, yielded greater depth of target word knowledge. Changes in 56 kindergartners’ depth of knowledge for each of 23 novel target words (N = 1,288) based on presentation in 1 of 3 conditions (read-aloud, teacher conversation, or both read-aloud and conversation) were explored and compared to control words that were never presented. A 2-level, cross-classification analysis modeled the postintervention score for each word for each child. Children’s word meaning knowledge improved most when words were presented via combined conversations and read-alouds. Vocabulary gains for words presented via conversations differed across classrooms. Practice or Policy: Both teacher conversations and read-aloud presentations of target vocabulary should be used together. Professional development for teachers’ effective vocabulary conversations may be needed.     

一种在MPEG-4编码过程中提高实时性的算法

本文提出了一种新的在MPEG-4编码过程中提高实时性的算法。算法采用双重筛选机制,充分利用了运动估计的结果提取运动对象。首先在运动估计过程中加入背景优先准则进行第一重筛选;然后根据运动估计后宏块的最小平均绝对差值分利用区域自适应门限进行第二重筛选,从而获得运动区域掩模;最后对掩模进行形态滤波和填充消除噪声点,最终得到运动区域。算法分别在硬件和软件平台上进行测试,结果表明提出的算法得到了理想的分割效果,较传统的在编码前进行运动对象提取的方法实时性大大提高了。
