Remarkable rate acceleration of SmI3-mediated iodination of acetates of Baylis-Hillman adducts in ionic liquid： facile synthesis of （Z）-allyl iodides

Stereoselective transformation of Baylis-Hillman acetates I into corresponding （Z）-allyl iodides 2 has been achieved by treatment of I with samarium triiodide in THF. Remarkable rate acceleration of samarium triiodide-mediated iodination of 1 was found when ionic liquid 1-n-butyl-3-methyl-imidazolium tetrafluroborate （[bmim]BF4） was used as reaction media in stead of THF. This novel approach proceeds readily at 50 ℃ within a few minutes to afford （Z）-allyl iodides 2 in excellent yields. A mechanism involving stereoselective iodination of the acetates of Baylis-Hillman adducts by samarium triiodide is described, in which a six-membered ring transition state played a key role in the stereoselective formation of 2.     

Student leadership in small group science inquiry

Background: Science educators have sought to structure collaborative inquiry learning through the assignment of static group roles. This structural approach to student grouping oversimplifies the complexities of peer collaboration and overlooks the highly dynamic nature of group activity.

Purpose: This study addresses this issue of oversimplification of group dynamics by examining the social leadership structures that emerge in small student groups during science inquiry.

Sample: Two small student groups investigating the burning of a candle under a jar participated in this study.

Design and method: We used a mixed-method research approach that combined computational discourse analysis (computational quantification of social aspects of small group discussions) with microethnography (qualitative, in-depth examination of group discussions).

Results: While in one group social leadership was decentralized (i.e., students shared control over topics and tasks), the second group was dominated by a male student (centralized social leadership). Further, decentralized social leadership was found to be paralleled by higher levels of student cognitive engagement.

Conclusions: It is argued that computational discourse analysis can provide science educators with a powerful means of developing pedagogical models of collaborative science learning that take into account the emergent nature of group structures and highly fluid nature of student collaboration.     

Attention-Deficit/Hyperactivity Disorder: Underlying Deficits in Achievement Motivation

This South African study aims at contributing to the debate regarding the processes underlying the core deficits of Attention-Deficit/Hyperactivity Disorder (ADHD) by investigating the motivational factors underlying the symptoms of ADHD. It investigates the difference between adolescents with ADHD (combined type) and adolescents without ADHD regarding their achievement motivation. The results add to previous knowledge regarding the motivational deficits demonstrated by ADHD children and provide a valuable insight into their achievement motivational patterns, especially regarding negative fear of failure and the motive to achieve. Recommendations are suggested regarding educational and therapeutic strategies to improve the ADHD child's motivation at home and at school.     

Exploring the pedagogical features of integrating essential competencies of scientific inquiry in classroom teaching

ABSTRACT

Background: As inquiry-based instruction is not universally implemented in science classrooms, it is crucial to introduce instructional strategies through the use of contextualized learning activities to allow students with different background knowledge and abilities to learn the essential competencies of scientific inquiry and promote their emotional perception and engagement.

Purpose: This study explores how essential scientific competencies of inquiry can be integrated into classroom teaching practices and investigates both typical and gifted secondary students’ emotional perception and engagement in learning activities.

Sample: A case teacher along with 226 typical and 18 gifted students from a suburban secondary school at Taiwan participated in this study.

Design and methods: After attending twelve 3-hour professional development workshops that focused on scientific inquiry teaching, the case teacher voluntarily developed and elaborated her own teaching activities through the discussions and feedback that she received from workshop participants and science educators. Quantitative and qualitative data were collected through activity worksheet, questionnaire, video camera, and tape recorders. Frequency distribution, Mann-Whitney U test, and discourse analysis were used for data analyses.

Results: Case teacher’s teaching activities provide contextual investigations that allow students to practice making hypotheses, planning investigations, and presenting and evaluating findings. Students’ learning outcomes reveal that typical students can engage in inquiry-based learning with positive emotional perception as well as gifted students regardless of their ability level. Both gifted and typical students’ positive emotional perception of and active engagement in learning provide fresh insight into feasible instructions for teachers who are interested in inquiry-based teaching but have little available time to implement such instructions into their classrooms.

Conclusions: The results of our work begin to address the critical issues of inquiry-based teaching by providing an exemplary teaching unit encompassing essential scientific competencies     

‘Come in with an open mind’: changing attitudes towards mathematics in primary teacher education

Background: The relationship between attitudes and behaviour has led to a focus on the role played by attitudes in the teaching and learning of mathematics.

Purpose: This paper reports on an investigation into student teachers’ self-reported attitudes towards mathematics in the context of a mathematics education programme. The programme had been developed by the authors in response to a new, reformed four-year undergraduate initial teacher education (ITE) for primary teachers in Ireland. The authors aimed to use the feedback to evaluate and develop the course further.

Sample: We report on the attitudes of 345 pre-service primary teachers enrolled in a four-year undergraduate ITE programme. 281 of these participants had matched survey data before and after participating in the mathematics education programme.

Method and Design: Four evaluation criteria were used as a conceptual framework for the evaluation of the mathematics education programme. A multi-method approach was taken in investigating the students’ attitudes to mathematics by using a scale as a quantitative measure of attitude alongside open-ended survey items that provided qualitative insights into changes in attitudes.

Results and conclusions: Results from the survey data suggested overall that the participants’ attitudes towards mathematics were more positive after they had experienced the mathematics education programme. Overall, the written responses suggested that according to self-reportage, participants perceived that participation in the mathematics education programme had affected their attitudes towards mathematics positively. Comments indicated that the ‘small group’ tutorial structure was particularly well received and was associated with opportunities to actively engage, explore, interact and reflect. Suggestions offered by the participants will be used to inform planning and development of the mathematics programme.     

Embodied experiences: Critical insights from Dewey for contemporary education

ABSTRACT

Background: Reflecting increased cross-disciplinary interest in the significance of the body in education, this paper considers that a greater appreciation of John Dewey’s conceptualisations of experience and habit would benefit contemporary theory- and practice-related concerns.

Sources of evidence and main argument: The paper draws upon pragmatist-informed epistemological insights into the nature of experience and the habitual body from John Dewey. In doing so, the paper highlights how embodied experiences could become more central to realising a diverse range of educational goals. These include contexts where students appreciate that embodied learning practices can play a reconstructive part in shaping their identity, as well as the culture and school environments they share with others.

Conclusion: The paper concludes by exemplifying and critiquing some conceptual possibilities which recognise the benefits of intensifying bodily experiences and cultivating related habits in everyday contemporary schooling.     

English teachers’ uses of motivational strategies beyond an established framework

ABSTRACT

Background: Although the usefulness of Dörnyei’s framework of motivational strategies to language teachers has been widely tested, motivational techniques that are not within the framework have less commonly been accounted for.

Purpose: This study explores the uses of motivational strategies beyond Dörnyei’s taxonomy, and the factors that cause English teachers to use them.

Methods: In total, 22 teachers of English as a foreign language (EFL) in Hong Kong participated in this study. Reflective journal data and interview data, supported by classroom observations, were collected and analysed qualitatively.

Findings: The results reveal that, while most of the reported strategies corresponded closely to Dörnyei’s recommendations, two additional macrostrategies – routine teaching activities and uses of authentic materials – were employed. The most predominant factor leading to the use of these two macrostrategies was a concern about feasibility.

Conclusions: This study hence suggests the need for a new line of research on strategies that are primarily instructional and secondarily motivational, as well as further studies that take the feasibility of motivational strategies into greater consideration.

Bring your own device – a snapshot of two Australian primary schools

Background: The use of 1:1 and Bring Your Own Device strategies in schools is in its infancy and little is known about how mobile devices such as tablets are being used to support educational practice.

Purpose: In this article, two suburban primary schools in Sydney, Australia were focused on with an aim to understand how mobile device strategies were developed and implemented and how the devices were being used in the schools.

Design and method: This qualitative study uses a case study method. It draws upon questionnaires, interviews and classroom observations, and builds upon previous research in English and Australian schools.

Findings: Results of the research indicate that the devices have only recently been incorporated into the school and suggest that their usage has been generally embraced by both school staff and parents. Key issues highlighted by these two schools included the importance of the school’s vision and uncertainty about the differences between models of provision. Participant responses also referenced some positive impacts on classroom practice, which amplify constructivist pedagogy: there were examples of device use extending student learning by supporting peer assessment, collaboration, research skills and projects.     

Implementation of routine electronic health record-based child abuse screening in General Emergency Departments

BackgroundRoutine child abuse screening is an approach to early identification of abuse. Previous studies evaluated paper-based screens; the widespread use of electronic health records suggests that screening is more likely to succeed if integrated into the electronic record.ObjectiveTo implement an electronic health record-based child abuse screen in a diverse hospital system and to evaluate the screening rate, rate of positive screens, and number of reports to Child Protective Services and assess whether hospital and patient characteristics are associated with these rates.Participants and settingChildren <13 years of age evaluated at one of 13 Emergency Departments within University of Pittsburgh Medical Center Health System.MethodsA previously validated child abuse screen was slightly modified and integrated into Cerner. Multivariable logistic regression models were used to estimate the odds of the outcomes of interest, controlling for key covariates.ResultsOf 17,163 eligible children: 68% received the screen of which 1.9% were positive. The rate of reports to Child Protective Services was higher among children who were screened (p < 0.0001). Younger children were more likely to be screened, have a positive screen, and have a report filed. There was no difference in the odds of being screened according to hospital teaching status, size or urban vs rural location.ConclusionsA child abuse screening tool can be integrated into the electronic health record in a large health-care network. The increased number of reports among children who were screened suggests that screening facilitates detection of suspected maltreatment.     

Class Scheduling

The purpose of this paper is to explore the desirability of using computer scheduling to allocate students into the activities (lectures, tutorials, practical classes) for courses requested and the possibility of integrating the scheduling into the enrolment process     

Book review

An equitable and democratised higher education system should, in principle, be permeable to the flow of populations with different social and/or cultural backgrounds, allowing access to any parts of the system. However, despite the democratisation efforts that took place in Portugal after the 1974 revolution, and although the student population is now much more diversified and heterogeneous than ever before, the particular routes to higher education still hinder the free access of students to some areas of the system.

Purpose

In this study, those different routes to higher education and the way they might influence students’ choices are analysed. Of particular interest was whether students tended to make choices based on feasibility rather than personal preference.

Sample

Data were collected through individual semi-structured interviews with 60 first year students (32 female and 28 male), from universities and polytechnics, both public and private, and from three first cycle study programmes (Arts, Pharmacy and Computer Engineering) in the urban area of the city of Porto.

Design and Methods

The analysis was a small scale qualitative investigation of Portuguese students’ perceptions underlying their choices in higher education. The sample selection took into account the diversity of the student population and sought to include different student profiles to gather contrasting cases and potentially contrasting views. Data gathered through interviews (conducted in 2009/2010) were systematised by means of a content analysis technique and submitted to a codification process according to a grid of categories that emerged from the analysis of data.

Results

Findings from this small scale exploration suggest that the majority of the students interviewed chose a study programme based on preference but based their choice of institution on feasibility.

Conclusions

The study provides insights into factors that limit student access to all parts of the higher education system, namely to some selective and more prestigious institutions.     

Teachers and students’ perception of competence-based education in the agricultural higher education system (Case of a student cooperative in Iran)

Purpose: This quantitative study sought to investigate the perceptions of teachers and students regarding competency-based education (CBE) principles at the College of Agriculture at Razi University.

Design: This research is a comparative analysis of two groups. The first group consists of undergraduate and graduate students majoring in agriculture who are members and non-members of student cooperatives (n?=?256). The second group consists of agricultural faculty members (n?=?59).

Findings: The results of this study show that students and teachers have different views with regard to the extent to which CBE principles are practiced in the College of Agriculture. Moreover, students with different learning patterns had different perceptions regarding the extent to which CBE is practiced, whereas teachers with different teaching patterns had the same perception of the application of CBE principles in the College of Agriculture.

Practical implications: This study has practical implications for agricultural higher education in general and colleges of agriculture in particular. Colleges of agriculture across Iran could encourage their students to establish and engage in student cooperatives so that the ‘what’ and ‘how’ aspects of CBE are put into practice.

Theoretical implications: This study has theoretical implications for CBE principles. For example, student cooperatives can be utilized by faculty members as one of the main strategies for developing CBE in agricultural colleges.

Originality/value: This study is original in that it moves from theory to practice when considering CBE.     

High school students’ scientific epistemological beliefs,self-efficacy in learning physics and attitudes toward physics: a structural equation model

Background: There are some theoretical evidences that explain the relationships between core beliefs (i.e., epistemological beliefs) and peripheral beliefs (self-efficacy in learning) in the literature. The close relationships of such type of beliefs with attitudes are also discussed by some researchers. Constructing a model that investigates these relationships by considering theoretical and empirical evidences can empower researchers to discuss these relationships more comprehensively.

Purpose: The purpose of this study is to explore the relationships among Turkish high school students’ scientific epistemological beliefs, self-efficacy in learning physics and their attitudes toward physics.

Sample: A total of 632 high school students participated in this study; however, 269 female and 229 male (a total of 498) high school students’ data were used.

Design and methods: Three distinct instruments that measure scientific epistemological beliefs, self-efficacy in learning physics and attitudes toward physics were combined into a unique questionnaire form and it was distributed to high school students. To explore the relationships among these variables, structural equation modeling was used.

Results: The results showed that scientific epistemological belief dimensions uncovered by the nature of knowing (source and justification) significantly and positively related to both self-efficacy in learning physics and attitudes toward other important physics dimensions. Additionally, self-efficacy in learning physics significantly and positively predicted attitudes toward multiple physics dimensions (importance, comprehension and requirement). However, epistemological belief dimensions related to the nature of knowledge (certainty and development) did not have significant impact on self-efficacy in learning physics or attitudes toward physics.

Conclusions: This study concludes that there are positive and significant relationships among Turkish high school students’ scientific epistemological beliefs, self-efficacy in learning physics and their attitudes toward physics.     

Facilitating student well-being: relationships do matter

Background: Alongside academic and vocational goals, schools are increasingly being called upon to address student well-being. Existing evidence suggests that strong relationships and a sense of connectedness in school communities are important for fostering subjective well-being. However, identifying the specific nature of such relational dynamics, and accommodating the ‘personal’ within school cultures increasingly dominated by ‘performance’ narratives, remains a problematic task.

Purpose: This paper draws on Honneth’s recognition theory to offer fresh insight into how relationships act to facilitate and limit the experience of well-being at school. We suggest that such an approach holds considerable potential for developing teachers’ understanding of the tacit and explicit ways they and their students experience being cared for, respected and valued and the ways in which such actions impact on well-being.

Design and methods: The paper reports the qualitative findings from a large mixed-method study, involving students and staff across primary and secondary schools in three regions of Australia. The qualitative phase involved focus groups with 606 primary and secondary students and individual interviews with 89 teachers and principals.

Results: Across the focus groups and interviews, students and teachers placed substantial emphasis on the importance of relationships, while reporting differences in their views about which relationships support well-being. Alongside this, there were differences in the importance teachers and students placed on each of the three strands of Honneth’s recognition theory (translated for this study as being cared for, respected and valued) for influencing student well-being.

Conclusions: The findings affirm the critical role that relationships play in promoting well-being in the context of schools. Using recognition theory to analyse students’ and teachers’ views and experiences of well-being provides much greater insight into how these relationships are enacted – this being through the mutual experience of being cared for, respected and valued – within the context of schools.

Framing the role of the school leader in OECD documents: A critical analysis

ABSTRACT

This paper explores the OECD framing of the role of the school leader in a series of its publications, drawing on role theory, using critical analysis of how school leaders’ roles are represented in a body of OECD texts. The research findings provide insight into the multi-faceted portrayal of the ‘ideal’ role of school leadership as framed by the OECD. The findings also show the dominance of classic scientific management ideas in the framing of the role of school leadership by the OECD. The study demonstrates how adopting role theory can provide a deeper understanding of how OECD discursive actions redraw new roles for those working in education.     

Exceeding expectations: scaffolding agentic engagement through assessment as learning

Background: The active involvement of learners as critical, reflective and capable agents in the learning process is a core aim in contemporary education policy in Australia, and is regarded as a significant factor for academic success. However, within the relevant literature, the issue of positioning students as agents in the learning process has not been fully examined and needs further exploration.

Purpose: This study aims to explore ways in which aspects of self-regulated learning theory may be integrated with the concept of agentic engagement into classroom practice. Specifically, the study seeks to scaffold students’ self-assessment capabilities and self-efficacy by using a formative assessment-as-learning process. The research examines how scaffolded planning, as part of the forethought phase in the Assessment as Learning (AaL) process, influences self-regulation and student agency in the learning process.

Sample: 126 students from school years two, four and six (student age groups 7, 9 and 11 years), and 7 teachers at an independent (co-educational, non-religious) primary school in the Northern Territory, Australia, participated in the study.

Design and methods: Conducted as a one-setting, cross-sectional practitioner research study, the data sources included students’ planning templates, writing samples, interviews with students and teachers and email correspondence with teachers. The data were analysed for emerging themes and interpreted from a framework of social cognitive theory.

Findings: In this study, students were given the opportunity and support to exercise agentic engagement. Findings suggested that, in particular, students who were identified by their teachers as low-achieving and/or with poor motivation, were perceived by the teachers as exceededing expectations by demonstrating relatively greater motivation, persistence, effort and pride in their work than would be the case usually.

Conclusions: The findings from this formative AaL study suggest that AaL has the potential to help scaffold primary students’ development of assessment capabilities.
