开源软件在高校的应用与推广策略研究

在UNESCO的大力推动下,MIT的“开放课件计划”已在世界范围内掀起了一场“开放式教育资源”(OERs)运动。而OECD的教育创新研究中心所提出的将“开放源代码软件”(OSS)作为开放式教育资源之必要组成部分的观点,又将OERs与OSS紧密地联系在一起,从技术角度为OERs运动提供了更强大的动力。本文以开放源代码在高校中的应用为研究主题,论述了OSS国外的应用状况及其对高校信息化建设的重要价值和促进作用,并对OSS在国外高校受到重视的原因进行了详细分析。以此为基础,研究者提出,在国内高校推广和应用OSS不仅可以有效地降低校园信息化的成本,更为重要的是,OSS体现了与高等教育机构相同的价值观念和哲学理念,即:知识是由全人类共同创造的,理应以开放的形式来向每一个成员提供。在论文的最后,研究者也提出在一些在国内高校中促进OSS应用的方法与建议。

Do Black students misbehave more? Investigating the differential involvement hypothesis and out-of-school suspensions

Black students are much more likely to be disciplined using out-of-school suspensions (OSS) compared with White students. One often-cited hypothesis, though relatively untested, is the role of misconduct and students attitudes that support deviant behavior. The differential involvement hypothesis suggests that disproportionate sanctioning may result if one group of students is engaged in greater levels of misbehavior compared with the other group. Using a national high school dataset, the author used various student-reported measures of misconduct (e.g., fighting) and 18 attitudes supporting deviant behavior (e.g., it is okay to disobey school rules) to investigate their association with receiving an OSS. Findings showed that misconduct and deviant attitudes were important factors in predicting the receipt of OSS though results indicated that Black students did not generally misbehave or endorse deviant attitudes more than White students did.     

The Rhetoric of Free: Open Source Software and Technical Communication During Economic Downturns

This article explores the ramifications of deploying free and open source software (F/OSS) for technical communication program development. Against the backdrop of the recession, the article draws on empirical research to examine how different stakeholders understand the F in F/OSS, its relationship with proprietary software, and the institutional contexts surrounding these technologies. It contributes four recommendations for working with F/OSS that might help programs shore up in tough times and thrive postdownturn.     

Inequitable Compliance: Implementation Failure of a Statewide Student Discipline Reform

Researchers and others in the education community are concerned about over-reliance on exclusionary discipline such as out-of-school suspension (OSS) and expulsion. Exclusionary discipline is associated with lower student achievement, higher risk of drop-out or grade retention, and involvement in the juvenile justice system. In response, many schools, districts, and states are moving toward less exclusionary consequences. In 2013, the Arkansas state legislature passed a bill prohibiting the use of OSS as a consequence for truancy. Yet, even after 3 school years, there has not been a complete elimination in the use of OSS for truancy. In this article, I use 8 years of student achievement, demographic, and disciplinary data from all Arkansas public schools to assess which school-level factors are associated with the use of OSS as a consequence for truancy in the year the law was passed, and which are associated with policy compliance in the following 3 years. I find schools that served more minority students, had higher rates of truancy, and higher rates of OSS were less likely to comply with the policy, all else equal. Combined, these results suggest that the types of schools likely targeted by this policy are the same ones not fully complying with it. As a result, the impact of policy reforms, which sound beneficial prima facie, may be limited if changes are not communicated well to schools, if there is not accountability to ensure compliance, and if there is not school capacity to handle discipline effectively.

Longitudinal disciplinary and achievement outcomes associated with school‐wide PBIS implementation level

Positive behavioral interventions and support (PBIS) is a multitiered framework for behavioral support that is being increasingly implemented in schools. Although research has linked PBIS to improved student outcomes, less research is longitudinal and considers both academic and behavioral outcomes. This study examined the relationships between changes in school‐wide (i.e., Tier I) PBIS implementation level and changes in disciplinary and achievement outcomes over a 2‐year period. Participants included 85 Ohio schools with data on PBIS implementation fidelity (from the tiered fidelity inventory, or TFI), out‐of‐school suspensions (OSSs), and statewide achievement tests for the 2015–2016 and 2016–2017 school years. Linear regressions were conducted to examine the degree to which changes in TFI Tier I scores predicted changes in OSS and achievement scores when controlling for school‐level demographic variables that also were related to the outcome variables. Changes in TFI Tier I scores was found to significantly predict changes in OSS per 100 students but not changes in achievement scores.     

School demographic variables and out‐of‐school suspension rates: A quantitative and qualitative analysis of a large,ethnically diverse school district

This study examined out‐of‐school suspensions (OSS) in a large, ethnically diverse school district using both quantitative and qualitative procedures. Pearson product moment correlations and semi‐partial correlations were used to identify those school‐level variables that showed the strongest relationships to the duplicated OSS rate among elementary schools (n = 97) and secondary schools (n = 45). Additionally, interviews were conducted with administrators and student support personnel from the 24 schools in the district with the highest suspension rates and 24 demographically matched schools with significantly lower suspension rates. The majority of these schools served a high percentage of children from low socioeconomic backgrounds. Although the correlational analyses indicated that student demographic variables (e.g., percentage of White students, percentage of Black students, percentage of students receiving free or reduced price lunch) were strongly related to a school's suspension rate, the school comparisons showed that not all schools serving a high percentage of children placed at risk have high suspension rates. Implications of the findings for school discipline reform are discussed. © 2002 Wiley Periodicals, Inc.     

Discipline Reform: The Impact of a Statewide Ban on Suspensions for Truancy

Chronic absenteeism and truancy have been linked to a variety of undesirable outcomes for students including increased risk of dropout, lower test scores, lower educational and social engagement, juvenile delinquency, and substance abuse. One controversial response to truancy is the use of exclusionary discipline, such as out-of-school suspensions (OSS). Out of concern that such a practice is counter-intuitive and likely not effective at improving student engagement or academic outcomes, some states have recently banned this practice altogether. This analysis uses Arkansas as a case study to estimate the impact of a state-level ban on the use of OSS for truancy on attendance—an important measure related to student engagement and opportunity to learn. Using an eight-year panel of student-level data in a difference-in-differences framework, we find no evidence of improvement in attendance for truant students. Implications for policy design, implementation, and evaluation are discussed.
