CO2对HCl-NaOH滴定体系的影响

在CO2共存的情况下，不同浓度的HCl-NaOH滴定体系的实验数据进行了分析评价。结果表明：当采用适中浓度的HCl-NaOH滴定体系，且HCl、NaOH浓度相同或相近时，在选用甲基橙作指示剂的条件下，实验结果准确度较高。     

语用协调在阅读理解中的作用

语用协调是语言交际过程中一种重要的语用调节机制和认知策略。它可以对语篇信息流中的预设信息做出适当调节,从而在不影响语篇连贯性的前提下使语篇合乎语言交际的经济原则。语用协调在语篇建构和语篇理解过程中发挥着十分重要的作用。因此,在英语阅读理解中有意识的运用语用协调的语篇功能,可以促进阅读理解的能力。     

皮亚杰建构主义对素质教育的启示

建构论是皮亚杰发生认识论的核心,他提出的主客体相互作用的双向建构理论,对我国素质教育的推行,以及形成新的教育模式,都具有深刻的启发性。总体来说主要有以下几方面的启示:有效的教学过程应是教和学的有机统一;教师应鼓励学生积极主动地参与课堂活动;教育活动要打破学生已有的平衡状态,指导和帮助学生建立新的平衡;有效的教学应培养和促进学生的自我调节;有效的教学应充分重视活动的重要性。     

高职院校实施“1+X”证书制度的价值、问题与对策

高职院校“1+X”证书制度的实施有助于实现学历教育与职业培训的相互贯通,进一步深化职业教育校企合作,提升技术技能型人才的培养质量。当前,高职院校在实施“1+X”证书制度的过程中还存在一些问题:高职院校重视度不够,“三教”改革的推进力度不足;“X”证书的影响力较小,社会认可度较低;“1+X”证书制度的对接不顺畅,缺乏课证融通制度的实施保障。因此,高职院校需要提升重视度,以“1+X”证书制度为基础,推动高职院校的“三教”改革,凝聚多方面的优势资源,提高“X”证书的社会影响力,健全课证融通制度,逐步完善“1+X”证书的配套制度体系。     

试论跨文化交际中平等交流意识的缺失及对策

跨文化交际是双向交流过程，交际双方都应了解彼此的文化特征并相互尊重对方的文化习惯。跨文化交际实践与研究应树立平等意识，不应存在文化迁就倾向。我们在学习吸收西方文化的同时，更应重视维护和研究如何用外语来推介自己的文化。     

Beyond a transmission model of communication

Elbers grapples with two persistent issues in psychology: (a) the role of the adult and the child in development, and (b) depictions of competence as context specific or generalized. Elbers' entrenchment in a transmission model of meaning undermines his portrayal of the child as an active participant in development. Furthermore, his characterization of competence as something in the head of the individual hinders his attempts to contextualize competence. We outline a framework informed by Vygotsky, Bakhtin, and others, which depicts both the formation and the functioning of mental processes (or competence) as fundamentally interactive. Mental functions arise in social interactions in which all participants accommodate each other, thus obviating the question of who is active or passive in the interaction. Furthermore, the social interactive origins of mental functioning impose a social context on all competencies. Such a framework facilitates movement away from the dilemmas which Elbers cogently raises.     

“What’s in it for Me?” A Study on Students’ Accommodation or Resistance during Group Work

This article explores students’ accommodation and resistance while participating in group work. The data collected are from fieldwork observations in several classrooms over the course of four terms in different secondary school classes in Sweden, and also from interviews with the students. Through this data analysis, we report that the students accommodated for such reasons as amusement, compliance, fulfilling expectations, and striving for high marks. The reasons for students’ resistance were blending, inability, stage fright, and vagueness. Macro-sociological concepts from Ziehe's cultural theory were used to capture explanations for students’ behaviour in order to understand why students, on a micro-sociological level, accommodate or resist when using group work as a learning mode. On the basis of results, three models of interpretation were developed, namely, individual, institutional, and structural.     

Do Proper Accommodation Assignments Make a Difference? Examining the Impact of Improved Decision Making on Scores for English Language Learners

Does it matter if students are appropriately assigned to test accommodations? Using a randomized method, this study found that individual students assigned accommodations keyed to their particular needs were significantly more efficacious for English language learners (ELLs) and that little difference was reported between students receiving incomplete or not recommended accommodations and no accommodations whatsoever. A sample of third and fourth grade ELLs in South Carolina (N = 272) were randomly assigned to various types of test accommodations on a mathematics assessment. Results indicated that those students who received the appropriate test accommodations, as recommended by a version of a computerized accommodation taxonomy for ELLs (the selection taxonomy for English language learners accommodations; STELLA), had significantly higher test scores than ELLs who received no accommodations or those who received incomplete or not recommended accommodation packages. Additionally, students who were given no test accommodations scored no differently than those students that received accommodation packages that were incomplete or not recommended, given the students' particular needs and challenges. These findings are important in light of research and anecdotal reports that suggest a general lack of systematicity in the current system of assigning accommodations and a tendency to give all available accommodations regardless of individual child characteristics. The results also have important implications for how future accommodation research should be structured to determine the benefits of particular accommodations and accommodation packages. This study would suggest that control and treatment groups should be assembled based on specific student needs in order for direct comparisons to be made.     

Navigating the complexity of disability support in tertiary education: perspectives of students and disability service staff

Access to education is a right for all students. This right is typically realised through the provision of disability support and reasonable adjustments to enable tertiary students with disabilities to participate on an equal footing with their peers. This paper presents perspectives of disability service staff and students about implementing and using reasonable adjustments. Data were collected at 2 tertiary institutions in Australia through interviews with 25 students with disabilities and 7 disability service staff. Data were thematically analysed. The complexity of and variability in the processes of negotiating and implementing disability support were identified as an overarching theme in the data. These processes involved engaging multiple parties. The task of negotiating reasonable adjustments is used to illustrate some of the complexities inherent in supporting students with disabilities. These findings challenge existing assumptions that support is easily accessible and simply provided. They highlight the complexity of using reasonable adjustments, and the tendency for this to be seen as a student responsibility. Finally, the findings imply that disability services need to reorient from a focus on care and concern towards a rights orientation and foster students’ skills in self-advocacy to better enable them to negotiate without disadvantage.     

‘I've never done a dissertation before please help me’: accommodating L2 students through course design

This article considers how course design accommodates the adaptation of L2 students into the early stages of the master's dissertation (Social Sciences and Humanities) at a UK university. I present a contrastive process-oriented analysis of two students' experiences on different courses, extracted from a 13-month ethnographic study in which students' self-reports (journals; interviews) were triangulated with their assignments, interviews with lecturers and classroom observation. I identify two ‘literacy events’ in the early stages: discussing the topic and preparing the proposal. In order to make visible these events, I deploy Lave and Wenger's Community of Practice model, while taking a post-structuralist view of learning as a dynamic between language, identities, power relations, affordances and agency. Findings show unequal support for these events on the two courses; I argue that this exemplifies significantly different ideologies relating to the accommodation of L2 students, and discuss implications for course design.
