Evaluating the feasibility of remotely administered curriculum-based measurement for students with autism: A pilot study

Students with autism may struggle to develop the academic skills necessary for success in school and beyond. Understanding and improving academic skills performance requires appropriate measurement approaches. One such option that has been minimally studied with students with autism is curriculum-based measurement (CBM). Coinciding with the need to study different approaches to academic skills measurement for students with autism was the global pandemic which forced a shift to remote service delivery with little warning. While some autistic students struggled with this shift, others thrived, raising questions about how to further support students with autism in virtual formats. The purpose of this study was to examine the feasibility of using remotely administered CBM for autistic students by studying both the practicality and acceptability of this approach. Five students with autism (Grades 2–5) participated in this pilot study, completing reading, math, and writing CBMs at three time points. Student behavior and assessor fidelity were collected to examine practicality; assessor ratings of usability provided insight regarding the acceptability of the approach. Results indicated that remotely administered CBM is feasible for some students with autism: all participants completed the study tasks with minimal behavioral difficulties, and assessor ratings of acceptability were high.     

一种收发不同频天线测试系统设计改造

本文介绍了一种带有非线性器件的射频通道天线的测试方法,针对这一种类型的天线系统,构建了一种收发不同频的天线测试系统。基于已有的室内天线远场测试系统,在不改变原有远场系统硬件配置以及软件系统的基础上,只添加一套对应的混频装置,就可完成对带有发射上变频与接收下变频通道的天线测量。系统的改造方案具有一定的通用性。在工程上对内置频率转换器件的这一类型天线方向图的精确测量具有一定的借鉴意义。

Measurement Invariance Testing with Many Groups: A Comparison of Five Approaches

With the increasing use of international survey data especially in cross-cultural and multinational studies, establishing measurement invariance (MI) across a large number of groups in a study is essential. Testing MI over many groups is methodologically challenging, however. We identified 5 methods for MI testing across many groups (multiple group confirmatory factor analysis, multilevel confirmatory factor analysis, multilevel factor mixture modeling, Bayesian approximate MI testing, and alignment optimization) and explicated the similarities and differences of these approaches in terms of their conceptual models and statistical procedures. A Monte Carlo study was conducted to investigate the efficacy of the 5 methods in detecting measurement noninvariance across many groups using various fit criteria. Generally, the 5 methods showed reasonable performance in identifying the level of invariance if an appropriate fit criterion was used (e.g., Bayesian information criteron with multilevel factor mixture modeling). Finally, general guidelines in selecting an appropriate method are provided.

论中国语境下Disinformation概念的对接、转换与重新阐释

[目的/意义]针对中西方理解与应用Disinformation概念存在较大差异这一现状,提出中国语境下这一概念的对接、转换与重新阐释,为围绕中国问题开展Disinformation研究创造条件,进而在我国开辟新的研究领域。[方法/过程]梳理分析中西方理解Disinformation概念的差异,然后基于这一概念的3种基本属性,提出Disinformation概念进入中国语境的基本路径,即对接→转换→重新阐释。[结果/结论]信息误导意图3种属性及施众、受众两个要素,是中西方Disinformation概念对接、转换的基础和依据;从信息和信息活动两个角度,提出中国语境下Disinformation概念的两种定义,Disinformation则译为误导性信息或信息误导与反误导。Disinformation概念经重新阐释,可应用于研究中国社会现象,解决中国现实问题。
