A comparative study of mothers’ beliefs and childrearing behaviour: The effect of the child’s disability and the mother’s educational level

The article presents the results of a data analysis intended to examine the relationship between children’s personality, maternal beliefs and childrearing behaviour and various disabilities on the one hand (mildly, moderate or severe mental handicap, sensorial handicap, developmental disabilities) and mothers’ educational level on the other. Data were taken from 102 mothers of disabled children between the ages of three and six. The children came from the Walloon Region of Belgium and were regularly counselled by an early intervention team (Services d’Aide Précoce — SAP). Variance analyses were performed on questionnaire data from the total sample (n=102). The questionnaires were based on the Five Factor Model of personality rating (Roskam, de Maere-Gaudissart, & Vandenplas-Holper, 2000), and on Sameroff’s levels of parental development for the rating of maternal beliefs. Factorial correspondence analyses were also performed on maternal self-reported childrearing behaviour as described in 50 interviews with mothers, analysed with a coding gird.     

Mach’s principle

The underlying idea in Mach’s principle is that the origin of inertia or mass of a particle is a dynamical quantity determined by the environment, in particular the rest of the matter in the universe. In this article, we discuss the role of this idea in the Brans-Dicke theory of gravitation and the Hoyle-Narlikar cosmology.     

Hubble, Hubble’s law and the expanding universe

Hubble’s name is associated closely with the idea of an expanding universe as he discovered the relation between the recession velocity and the distances of galaxies. Hubble also did a lot of pioneering work on the distribution of galaxies in the universe. In this article we take a look at Hubble’s law and discuss how it relates with models of the universe. We also give a historical perspective of the discoveries that led to the Hubble’s law.     

Teacher interpersonal behaviour and student achievement in English as a Foreign Language classrooms in China

We examined the relationship between English as a Foreign Language (EFL) teachers’ interpersonal behaviour and students’ fluency in English in secondary education in China. A total of 160 students from four classes in the southwest part of China were asked to assess their teachers’ interpersonal behaviour using the Questionnaire on Teacher Interaction (QTI). This was the first time that the QTI was successfully translated and used (in EFL classrooms) in China. Cronbach’s α reliability coefficients for the scales were adequate, while confirmatory factor analyses provided support for the theoretical framework behind the questionnaire. Results showed that teacher uncertainty was negatively correlated with student achievement. Furthermore, the degree of teacher cooperation with students was the only significant predictor for student achievement, but its effect disappeared when student background variables were taken into account. Results also indicated a discrepancy between students’ perceptions of preferred and actual teacher interpersonal behaviour. The tolerant-authoritative profile was the most common interpersonal style based on Chinese students’ perceptions.     

Āryabhata and axial rotation of earth

In the first part of this series, we discussed the celestial sphere and Aryabhata’s principle of axial rotation; in this part we shall discuss in detail the concept of sidereal day and then mention Aryabhata’s computations on the duration of sidereal day.     

The importance of being ignorant

In many real life situations, we have to draw conclusions from data which are not complete and have been affected by measurement errors. Such problems have been addressed from the time of Bayes and Laplace (late 1700’s) using concepts which parallel Boltzmann’s use of entropy in thermal physics. The idea is to assign probabilities to different possible conclusions from a given set of data. A critical — and sometimes controversial — input is a ‘prior probability’, which represents our knowledge before any data are given or taken! This body of ideas is introduced in this article with simple examples.     

Unpacking the CRT in Negotiating White Science

In this forum, we summarize CRT’s origins, tenets common to most CRT writings, and CRT’s evolution. We discuss Yerrick’s article Negotiating White Science with respect to certain CRT premises. Specifically, we use the CRT tenet of racism as emphasized in first- and second-generation CRT and CRT elements liberal racial ideology and voices of color to critically examine Yerrick’s propositions.     

Origin (?) of the Universe

The expansion of the universe was established based on observations made in the 1920’s, of the Doppler shift of light from galaxies. The proportionality between velocity and distance is the famous Hubble Law. Simplified mathematical models of the universe are based on the idea, which is supported by observations, that there are no preferred locations or directions in space.     

Conditional inference and advanced mathematical study: further evidence

In this paper, we examine the support given for the ‘theory of formal discipline’ by Inglis and Simpson (Educational Studies Mathematics 67:187–204, 2008). This theory, which is widely accepted by mathematicians and curriculum bodies, suggests that the study of advanced mathematics develops general thinking skills and, in particular, conditional reasoning skills. We further examine the idea that the differences between the conditional reasoning behaviour of mathematics and arts undergraduates reported by Inglis and Simpson may be put down to different levels of general intelligence in the two groups. The studies reported in this paper call into question this suggestion, but they also cast doubt on a straightforward version of the theory of formal discipline itself (at least with respect to university study). The paper concludes by suggesting that either a pre-university formal discipline effect or a filtering effect on ‘thinking dispositions’ may give a better account for the findings.     

Enhancing part-time in-service teacher training programmes to facilitate rural teacher development in China

Despite the frequent criticisms directed toward them, in-service teacher training (INSET) programmes remain one of the most commonly used approaches for enhancing teachers’ professional development. This article reports on a study that examined the effects of a part-time masters of education INSET programme based in Central China. The main source of data was reflective papers written by 38 teacher participants; classroom observations and informal interviews also helped reveal the teachers’ perspectives on the programme. Whilst the programme was very popular, and had a variety of positive impacts on the teachers’ professional development, the programme paradigm involved several drawbacks. The results suggest that part-time INSET programmes for rural teachers should be supplemented by various other forms of teacher development activities to meet the dual goals of developing such programmes and providing professional development for teachers.     

Motives,attitudes and approaches to studying in distance education

This study investigated the relationships between demographic characteristics, motives and attitudes to studying, self-reported study behaviour and measures of outcome. Students taking courses by distance learning received a postal survey containing a short form of the Motivated Strategies and Learning Questionnaire (MSLQ) and the Revised Approaches to Studying Inventory (RASI). Path analysis was used to assess the causal relationships among 395 students’ age, gender and prior qualifications, their scores on the MSLQ and the RASI and their marks. Evidence was obtained for the causal efficacy of most of the paths among the main components. In particular, the causal link between variations in students’ motives and attitudes and variations in their study behaviour is bidirectional.     

Cost management based security framework in mobile ad hoc networks

INTRODUCTION Mobile ad hoc networks are under active research focused on issues such as routing, security (Venkatra- man and Agrawal, 2003) and data management (Fan and Zhang, 2004). People have proposes many kinds of security mechanisms such as SAR (Yi et al., 2002), SRP (Papadimitratos and Haas, 2002), ARAN (San- zgiri et al., 2002), ARIADNE (Hu et al., 2005) and SEAD (Hu et al., 2002) for networks. The resource consumptions of security mechanisms are always large in mobile …     

Class-first analysis in a continuum: an approach to the complexities of schools, society, and insurgent science

This essay addresses Katherine Richardson Bruna’s paper: Mexican Immigrant Transnational Social Capital and Class Transformation: Examining the Role of Peer Mediation in Insurgent Science, through five main points. First, I offer a comparison between the traditional analysis of classism in Latin America and Richardson Bruna’s call for a class-first analysis in the North American social sciences where there has been a tendency to obviate the specific examination of class relations and class issues. Secondly, I discuss that a class-first analysis solely cannot suffice to depict the complex dimensions in the relations of schools and society. Thus, I suggest a continuum in the class-first analysis. Third, I argue that social constructions surrounding issues of language, ethnicity, and gender necessarily intersect with issues of class and that, in fact, those other constructions offer compatible epistemologies that aid in representing the complexity of social and institutional practices in the capitalist society. Richardson Bruna’s analysis of Augusto’s interactions with his teacher and peers in the science class provides a fourth point of discussion in this essay. As a final point in my response I discuss Richardson Bruna’s idea of making accessible class-first analysis knowledge to educators and especially to science teachers.     

Why do learning goals (not) work: a reexamination of the hypothesized effectiveness of learning goals based on students’ behaviour and cognitive processes

Explicitly informing students about learning goals has been argued to foster intentional learning. This study tested three theoretical hypotheses regarding the facilitating effects of learning goals by investigating 72 students’ actual reading behaviour and cognitive processes (i.e., the use of learning goals). Participants studied a text presented on 15 separate computer screens with/without learning goals. In line with the three hypotheses, the analyses focused on three aspects: students’ interpretations of the learning goals, information selection processes and monitoring behaviour. Results indicated variability among students in their perceptions of the learning goals in terms of goal consistency and specificity. Students in the learning goal condition recorded more goal-relevant information in their notes. However, only few students deliberately used learning goals to monitor their goal-directed activities while studying the text. Analysis of students’ reading behaviour and cognitive processes suggests that the absence of significant performance differences between the conditions can be explained by referring to students’ actual use of learning goals.     

Āryabhata and axial rotation of Earth

Āryabhata (born 476 CE) is regarded as a pioneer of mathematical astronomy in ancient India. In this three-part article, I shall discuss one important contribution of Āryabhata in astronomy involving the least technical background —the principle of axial rotation (Part 1) and computations on the sidereal day (Part 2). Portions of 4 verses, pertaining to Earth’s rotation, from his famous treatise Āryabhatīya will be quoted. In Part 3, I shall give a brief historical account on the concept of axial rotation of Earth.     

A fusion of horizons: students’ encounters withWill and Wave

In a case study, I applied philosophical hermeneutic principles in an advanced level EFL writing class in Taiwan. A “fusion of horizons” occurs at the junction of two intertwined interpretations: one from our socio-historical tradition and the other from our experience of novel phenomena. I explored students’ hermeneutic horizons in relation to Nietzsche’s textWill and Wave. Data collection was through classroom observations, informant interviews, and an analysis of three students’ interpretive essays. The results indicated that students experienced particular difficulties comprehending metaphors and the author’s purpose. Comprehension was a painstaking effort for most students because of their perceived ambiguity of Nietzsche’s message. Nevertheless, the text evoked personal stories and new perspectives for some students     

Students’ Reasoning about the Future of Disturbed or Protected Ecosystems & the Idea of the ‘Balance of Nature’

This paper is part of a larger study that aims at highlighting students’ interpretations of the idea of the ‘Balance of Nature’, as well as its use in their reasoning about the future of an ecosystem, in order to subsequently develop a learning environment that might promote a reconsideration of its validity and usefulness. Our focus here is particularly set on whether and how non biology-major students use this idea when making predictions about (a) the future of an ecosystem that is supposed to have suffered a human-driven disturbance, and (b) the future of an ecosystem that is supposed to be protected against such disturbances. Administering a questionnaire of 12 items - 4 of which concern us here - to 61 1st-year educational sciences students at the University of Patras, we traced - among others - their reasoning about (a) the future of three ecosystems (forest, sea, lake), supposed to have suffered different human-driven disturbances (fire, oil spill, new population introduction), and (b) the future of a protected forest ecosystem of a national park. According to our findings, most of the students found it very likely for a disturbed ecosystem to fully recover its initial state - mainly due to a ‘recovery process’ or inherent ‘recovery mechanisms’ - showing a strong belief in an extremely resilient ‘Balance of Nature’. Moreover, most of them appeared to believe that if human-protected, an ecosystem will be in a continuous ‘balance’, while very few were skeptical enough to claim a non-predictable future for it.     

Innovative Work Behaviour in Vocational Colleges: Understanding How and Why Innovations Are Developed

In workplaces, innovative products and processes are required to address emerging problems and challenges. Therefore, understanding of employees’ innovative work behaviour, including the generation, promotion, and realisation of ideas as components of this behaviour is important. In particular, what fosters innovation development and what triggers these activities is important for its promotion and adoption in contemporary workplaces. To investigate how and why innovations at work are developed and enacted, an explorative study comprising structured interviews with vocational teachers in the German vocational system was conducted. The teachers reported on activities they undertook during the development of a specific innovation. Furthermore, they provided information on factors that made this innovation necessary and that they were activated by. The study indicates that even when opportunities for innovation development existed in a workplace, the needs and goals of teachers were pivotal for these opportunities to be recognised and teachers’ innovative work behaviour to be triggered. By analysing vocational teachers’ work activities, we found that the development of innovations was a complex, iterative and primarily social process. By encouraging teachers to act on opportunities for change and by establishing a collaborative structure at schools, innovation development can be facilitated. We also found that throughout the development of an innovation, reflection played an important role. If the importance of reflective activities is acknowledged by workplaces such as these participants’ vocational schools, this not only fosters innovations but also the teachers’ professional development.
