Investigating problem-based learning in Saudi Arabian mathematics education: a TIMSS-related study

The aim of this study is to investigate the effectiveness of problem-based learning (PBL) on students’ mathematical performance. This includes mathematics achievement and students’ attitudes towards mathematics for third and eighth grade students in Saudi Arabia. Mathematics achievement includes, knowing, applying, and reasoning domains, while students’ attitudes towards mathematics covers, ‘Like learning mathematics’, ‘value mathematics’, and ‘a confidence to learn mathematics’. This study goes deeper to examine the interaction of a PBL teaching strategy, with trained face-to-face and self-directed learning teachers, on students’ performance (mathematics achievement and attitudes towards mathematics). It also examines the interaction between different ability levels of students (high and low levels) with a PBL teaching strategy (with trained face-to-face or self-directed learning teachers) on students’ performance. It draws upon findings and techniques of the TIMSS international benchmarking studies. Mixed methods are used to analyse the quasi-experimental study data. One -way ANOVA, Mixed ANOVA, and paired t-tests models are used to analyse quantitative data, while a semi-structured interview with teachers, and author’s observations are used to enrich understanding of PBL and mathematical performance. The findings show that the PBL teaching strategy significantly improves students’ knowledge application, and is better than the traditional teaching methods among third grade students. This improvement, however, occurred only with the trained face-to-face teacher’s group. Furthermore, there is robust evidence that using a PBL teaching strategy could raise significantly students’ liking of learning mathematics, and confidence to learn mathematics, more than traditional teaching methods among third grade students. Howe ver, there was no evidence that PBL could improve students’ performance (mathematics achievement and attitudes towards mathematics), more than traditional teaching methods, among eighth grade students. In 8th grade, the findings for low achieving students show significant improvement compared to high achieving students, whether PBL is applied or not. However, for 3th grade students, no significant difference in mathematical achievement between high and low achieving students was found. The results were not expected for high achieving students and this is also discussed. The implications of these findings for mathematics education in Saudi Arabia are considered.

Direitos do aluno em contexto escolar : um estudo comparado entre o Ensino Secundário Público e o privado no Concelho de Lisboa

Considerando o importante papel que as instituições educativas desempenham na formação das crianças e dos jovens, o respeito pelos direitos dos alunos é condição fundamental, para lhes proporcionar uma educação de qualidade. Partindo desta consciência, resolvemos efetuar um estudo de caso, numa escola da rede pública de ensino e numa escola da rede privada de ensino, ambas situadas no concelho de Lisboa, com o objetivo de conhecer as perceções dos alunos sobre a promoção dos seus direitos em contexto escolar e descortinar as semelhanças e as diferenças entre os dois contextos educativos, atendendo à diferente natureza jurídica das duas instituições. Para concretizarmos esse objetivo, formulámos as seguintes perguntas derivadas, cujas respostas procuraremos obter no decurso do nosso estudo: (i) os alunos têm conhecimento de que são titulares de direitos?; (ii) exercem os seus direitos em condições de plena igualdade e sem qualquer discriminação?; (iii) o interesse superior do aluno é a primordial consideração que a Escola tem em conta, em todos os assuntos que lhe dizem respeito?; (iv) o direito à vida, à sobrevivência e ao desenvolvimento dos alunos é garantido na Escola? e (v) a opinião dos alunos é tida em consideração, em todos os assuntos que lhes dizem respeito?. Para atingirmos os objetivos que delineamos, desenvolvemos um estudo de caso, recorrendo a uma abordagem metodológica predominantemente qualitativa, com recurso a técnicas variadas, designadamente a entrevista, o inquérito por questionário e a análise documental. Procedemos à revisão da literatura, de acordo com as áreas conceptuais previamente definidas, que se consubstanciaram nos princípios gerais de direito internacional, consignados na Convenção sobre os Direitos da Criança de 1989, e à luz dos quais todos os direitos nela constantes devem ser interpretados: o princípio da não discriminação, o princípio do interesse superior da criança, o direito à vida, à sobrevivência e ao desenvolvimento, e o princípio do respeito pelas opiniões da criança. A análise dos conceitos e da diferente natureza jurídica das duas instituições foi, também, objeto do nosso estudo. Por outro lado, a legislação portuguesa relacionada com os direitos dos alunos, também, foi por nós revista neste estudo, nomeadamente, os diversos estatutos do aluno que se sucederam no tempo. A análise dos resultados obtidos permitiu-nos concluir que o respeito dos direitos dos alunos, nas suas diversas dimensões, não foi ainda totalmente conseguido, sobretudo o seu direito à não discriminação e o seu direito à participação a nível micro e meso. Não se podendo generalizar o estudo, a comunidade educativa tem de desenvolver um esforço para a compreensão da dimensão e da importância do respeito dos direitos dos alunos, sobretudo na criação de um clima democrático, que favoreça a plena igualdade de oportunidades a todos os alunos e a livre escolha do projeto educativo pelas famílias das crianças e dos jovens.

Sobre (vivência) e mortalidade de pequenos negócios: o caso de mercados varejistas potiguares

This paper‟s starting point was the objective of understanding the relation between the reasons pointed out by small businesses owners for the continuity or shutdown of their businesses, and the reasons presented by the Environmental Theories. The paper discusses the Environmental Theories understand that it is supported by a systemic metaphor speech, discussing the theme in terms of organizational survival and mortality . The text reviews the literature showing the changes in the administrative thinking regarding the organization versus environment relation, and presenting general ideas about the micro and small businesses. In methodological terms, the qualitative approach was used in the research. Regarding the data collection technique, an in-depth thematic interview was used. It was carried out considering the elements of the techniques of life history and oral history, always giving priority to real world related narratives told by the interviewed subjects. The empirical corpus of the research was made up of seven owners of small retail businesses in two Potiguar cities: Natal and Mossoró. The interpretative and analytical process focused, at first, on the reflexive dialogue with each one of the owners‟ professional life history and business management experience, constituting the first level of analysis: reflections on individual narratives; and, afterwards, the interpretative process was developed through the analysis of all the subjects‟ statements, identifying the recurring themes and constituting the second level of analysis: reflection on the totalizing narrative. The themes identified in the totalizing narrative, that refer to the continuity of the businesses are: evolution, control, fidelity, liking what one does for a living. The themes that came up as reasons for shutdown are: lack of empathy with the business, lack of evolution, competition problems, suppliers and the government. The text synthesizes its comprehensions affirming that the reasons associated with continuity and shutdown of small markets, for this group of owners specifically, come up as a permanent tension between the volunteerism (quite human) and the determinism (systemic). The tension is shown in testimonies that at the same time evoke the organicist systemic logic through the themes evolution/no evolution, and also counterpoints with themes related to the interested human action, based on desires, feelings and personal convictions such as: liking what one does/ lack of empathy. As for the reflexive dialogue between the postulates of the Environmental Theories and the narratives, the results make it possible to affirm that, differently from the tension expressed by the subjects while talking about their reasons, the reasons associated with survival and mortality of businesses according to the Environmental Theories are theoretically polarized, seeming to preach options that are stagnated and shaping towards the subjects involved in the organization-environment relation

Estimating abundance and spatial distribution patterns of the bubble crab Dotilla fenestrata (Crustacea : Brachyura)

The bubble crab Dotilla fenestrata forms very dense populations on the sand flats of the eastern coast of Inhaca Island, Mozambique, making it an interesting biological model to examine spatial distribution patterns and test the relative efficiency of common sampling methods. Due to its apparent ecological importance within the sandy intertidal community, understanding the factors ruling the dynamics of Dotilla populations is also a key issue. In this study, different techniques of estimating crab density are described, and the trends of spatial distribution of the different population categories are shown. The studied populations are arranged in discrete patches located at the well-drained crests of nearly parallel mega sand ripples. For a given sample size, there was an obvious gain in precision by using a stratified random sampling technique, considering discrete patches as strata, compared to the simple random design. Density average and variance differed considerably among patches since juveniles and ovigerous females were found clumped, with higher densities at the lower and upper shore levels, respectively. Burrow counting was found to be an adequate method for large-scale sampling, although consistently underestimating actual crab density by nearly half. Regression analyses suggested that crabs smaller than 2.9 mm carapace width tend to be undetected in visual burrow counts. A visual survey of sampling plots over several patches of a large Dotilla population showed that crab density varied in an interesting oscillating pattern, apparently following the topography of the sand flat. Patches extending to the lower shore contained higher densities than those mostly covering the higher shore. Within-patch density variability also pointed to the same trend, but the density increment towards the lowest shore level varied greatly among the patches compared.

Development of semicrystalline morphology of poly(L-lactic acid) during processing of a vascular scaffold

New and promising treatments for coronary heart disease are enabled by vascular scaffolds made of poly(L-lactic acid) (PLLA), as demonstrated by Abbott Vascular’s bioresorbable vascular scaffold. PLLA is a semicrystalline polymer whose degree of crystallinity and crystalline microstructure depend on the thermal and deformation history during processing. In turn, the semicrystalline morphology determines scaffold strength and biodegradation time. However, spatially-resolved information about the resulting material structure (crystallinity and crystal orientation) is needed to interpret in vivo observations.

The first manufacturing step of the scaffold is tube expansion in a process similar to injection blow molding. Spatial uniformity of the tube microstructure is essential for the consistent production and performance of the final scaffold. For implantation into the artery, solid-state deformation below the glass transition temperature is imposed on a laser-cut subassembly to crimp it into a small diameter. Regions of localized strain during crimping are implicated in deployment behavior.

To examine the semicrystalline microstructure development of the scaffold, we employed complementary techniques of scanning electron and polarized light microscopy, wide-angle X-ray scattering, and X-ray microdiffraction. These techniques enabled us to assess the microstructure at the micro and nano length scale. The results show that the expanded tube is very uniform in the azimuthal and axial directions and that radial variations are more pronounced. The crimping step dramatically changes the microstructure of the subassembly by imposing extreme elongation and compression. Spatial information on the degree and direction of chain orientation from X-ray microdiffraction data gives insight into the mechanism by which the PLLA dissipates the stresses during crimping, without fracture. Finally, analysis of the microstructure after deployment shows that it is inherited from the crimping step and contributes to the scaffold’s successful implantation in vivo.

Hyperlinks in e-books : expanding the functionality of end-notes

With its powerful search engines and billions of published pages, the Worldwide Web has become the ultimate tool to explore the human experience. But, despite the advent of the digital revolution, e-books, at their core, have remained remarkably similar to their printed siblings. This has resulted in a clear dichotomy between two ways of reading: on one side, the multi-dimensional world of the Web; on the other, the linearity of books and e-books. My investigation of the literature indicates that the focus of attempts to merge these two modes of production, and hence of reading, has been the insertion of interactivity into fiction. As I will show in the Literature Review, a clear thrust of research since the early 1990s, and in my opinion the most significant, has concentrated on presenting the reader with choices that affect the plot. This has resulted in interactive stories in which the structure of the narrative can be altered by the reader of experimental fiction. The interest in this area of research is not surprising, as the interaction of readers with the fabric of the narrative provides a fertile ground for exploring, analysing, and discussing issues of plot consistency and continuity. I found in the literature several papers concerned with the effects of hyperlinking on literature, but none about how hyperlinked material and narrative could be integrated without compromising the narrative flow as designed by the author. It led me to think that the researchers had accepted hypertextuality and the linear organisation of fiction as being antithetical, thereby ignoring the possibility of exploiting the first while preserving the second. All the works I consulted were focussed on exploring the possibilities provided to authors (and readers) by hypertext or how hypertext literature affects literary criticism. This was true in earlier works by Landow and Harpold and remained true in later works by Bolter and Grusin. To quote another example, in his book Hypertext 3.0, Landow states: “Most who have speculated on the relation between hypertextuality and fiction concentrate [...] on the effects it will have on linear narrative”, and “hypertext opens major questions about story and plot by apparently doing away with linear organization” (Landow, 2006, pp. 220, 221). In other words, the authors have added narrative elements to Web pages, effectively placing their stories in a subordinate role. By focussing on “opening up” the plots, the researchers have missed the opportunity to maintain the integrity of their stories and use hyperlinked information to provide interactive access to backstory and factual bases. This would represent a missing link between the traditional way of reading, in which the readers have no influence on the path the author has laid out for them, and interactive narrative, in which the readers choose their way across alternatives, thereby, at least to a certain extent, creating their own path. It would be, to continue the metaphor, as if the readers could follow the main path created by the author while being able to get “sidetracked” into exploring hyperlinked material. In Hypertext 3.0, Landow refers to an “Axial structure [of hypertext] characteristic of electronic books and scholarly books with foot-and endnotes” versus a “Network structure of hypertext” (Landow, 2006, p. 70). My research aims at generalising the axial structure and extending it to fiction without losing the linearity at its core. In creative nonfiction, the introduction of places, scenes, and settings, together with characterisation, brings to life the facts without altering them; while much fiction draws on facts to provide a foundation, or narrative elements, for the work. But how can the reader distinguish between facts and representations? For example, to what extent do dialogues and perceptions present what was actually said and thought? Some authors of creative nonfiction use end-notes to provide comments and citations while minimising disruption the flow of the main text, but they are limited in scope and constrained in space. Each reader should be able to enjoy the narrative as if it were a novel but also to explore the facts at the level of detail s/he needs. For this to be possible, end-notes should provide a Web-like way of exploring in more detail what the author has already researched. My research aims to develop ways of integrating narrative prose and hyperlinked documents into a Hyperbook. Its goal is to create a new writing paradigm in which a story incorporates a gateway to detailed information. While creative nonfiction uses the techniques of fictional writing to provide reportage of actual events and fact-based fiction illuminates the affectual dimensions of what happened (e.g., Kate Grenville’s The Secret River and Hilary Mantel’s Wolf Hall), Hyperbooks go one step further and link narrative prose to the details of the events on which the narrative is based or, more in general, to information the reader might find of interest. My dissertation introduces and utilises Hyperbooks to engage in two parallel types of investigation Build knowledge about Italian WWII POWs held in Australia and present it as part of a novella in Hyperbook format. Develop a new piece of technology capable of extending the writing and reading process.

On multimodality of obnoxious faclity location models

Obnoxious single facility location models are models that have the aim to find the best location for an undesired facility. Undesired is usually expressed in relation to the so-called demand points that represent locations hindered by the facility. Because obnoxious facility location models as a rule are multimodal, the standard techniques of convex analysis used for locating desirable facilities in the plane may be trapped in local optima instead of the desired global optimum. It is assumed that having more optima coincides with being harder to solve. In this thesis the multimodality of obnoxious single facility location models is investigated in order to know which models are challenging problems in facility location problems and which are suitable for site selection. Selected for this are the obnoxious facility models that appear to be most important in literature. These are the maximin model, that maximizes the minimum distance from demand point to the obnoxious facility, the maxisum model, that maximizes the sum of distance from the demand points to the facility and the minisum model, that minimizes the sum of damage of the facility to the demand points. All models are measured with the Euclidean distances and some models also with the rectilinear distance metric. Furthermore a suitable algorithm is selected for testing multimodality. Of the tested algorithms in this thesis, Multistart is most appropriate. A small numerical experiment shows that Maximin models have on average the most optima, of which the model locating an obnoxious linesegment has the most. Maximin models have few optima and are thus not very hard to solve. From the Minisum models, the models that have the most optima are models that take wind into account. In general can be said that the generic models have less optima than the weighted versions. Models that are measured with the rectilinear norm do have more solutions than the same models measured with the Euclidean norm. This can be explained for the maximin models in the numerical example because the shape of the norm coincides with a bound of the feasible area, so not all solutions are different optima. The difference found in number of optima of the Maxisum and Minisum can not be explained by this phenomenon.

Investigating the Death of the Early Paleozoic Moyero River Geomagnetic Superchron: Middle Ordovician Paleomagnetism from Estonia

Flat-lying Early and Middle Ordovician limestones exposed on the North margin of Estonia provide key insights into the early Paleozoic biosphere and climatic history of the Baltic Platform, and potentially offer a site for calibrating the duration of the proposed Moyero River Reversed Superchron. Past paleomagnetic analyses on these rocks have been focused primarily on determining paleomagnetic pole positions and have been hampered by relatively weak remanent magnetizations. We therefore applied techniques of the Rock and Paleomagnetic Instrument Development (RAPID) consortium using thin-walled, low-noise quartz glass sample holders on an automatic system to enhance magnetostratigraphic resolution. Our results, based on over 300 oriented core samples spanning the stratigraphic interval from the Volkhov stage, up through the Lasnamägi stage, confirm previous work isolating a stable characteristic magnetization of reversed polarity, and furthermore confirm the presence of an interval of magnetically Reversed polarity spanning an interval of at least 15 million year duration. In addition, we recognize a magnetic overprint of presumed Normal polarity held in antiferromagnetic phases, of presumed Permian age, based on the apparent polar wander path given by (Plado et al., 2010).

Climate change and irrigation water requirement at Jaguaribe river basin, semi-arid northeast of Brazil.

Summary: Climate change has a potential to impact rainfall, temperature and air humidity, which have relation to plant evapotranspiration and crop water requirement. The purpose of this research is to assess climate change impacts on irrigation water demand, based on future scenarios derived from the PRECIS (Providing Regional Climates for Impacts Studies), using boundary conditions of the HadCM3 submitted to a dynamic downscaling nested to the Hadley Centre regional circulation model HadRM3P. Monthly time series for average temperature and rainfall were generated for 1961-90 (baseline) and the future (2040). The reference evapotranspiration was estimated using monthly average temperature. Projected climate change impact on irrigation water demand demonstrated to be a result of evapotranspiration and rainfall trend. Impacts were mapped over the target region by using geostatistical methods. An increase of the average crop water needs was estimated to be 18.7% and 22.2% higher for 2040 A2 and B2 scenarios, respectively. Objective ? To analyze the climate change impacts on irrigation water requirements, using downscaling techniques of a climate change model, at the river basin scale. Method: The study area was delimited between 4º39?30? and 5º40?00? South and 37º35?30? and 38º27?00? West. The crop pattern in the target area was characterized, regarding type of irrigated crops, respective areas and cropping schedules, as well as the area and type of irrigation systems adopted. The PRECIS (Providing Regional Climates for Impacts Studies) system (Jones et al., 2004) was used for generating climate predictions for the target area, using the boundary conditions of the Hadley Centre model HadCM3 (Johns et al., 2003). The considered time scale of interest for climate change impacts evaluation was the year of 2040, representing the period of 2025 to 2055. The output data from the climate model was interpolated, considering latitude/longitude, by applying ordinary kriging tools available at a Geographic Information System, in order to produce thematic maps.

Spatio-temporal modeling of data imputation for daily rainfall series in homogeneous zones.

Spatio-temporal modelling is an area of increasing importance in which models and methods have often been developed to deal with specific applications. In this study, a spatio-temporal model was used to estimate daily rainfall data. Rainfall records from several weather stations, obtained from the Agritempo system for two climatic homogeneous zones, were used. Rainfall values obtained for two fixed dates (January 1 and May 1, 2012) using the spatio-temporal model were compared with the geostatisticals techniques of ordinary kriging and ordinary cokriging with altitude as auxiliary variable. The spatio-temporal model was more than 17% better at producing estimates of daily precipitation compared to kriging and cokriging in the first zone and more than 18% in the second zone. The spatio-temporal model proved to be a versatile technique, adapting to different seasons and dates.

Inter-industry analysis and monetary policy evaluations in the Korean flow of funds accounts

This study mainly aims to provide an inter-industry analysis through the subdivision of various industries in flow of funds (FOF) accounts. Combined with the Financial Statement Analysis data from 2004 and 2005, the Korean FOF accounts are reconstructed to form "from-whom-to-whom" basis FOF tables, which are composed of 115 institutional sectors and correspond to tables and techniques of input–output (I–O) analysis. First, power of dispersion indices are obtained by applying the I–O analysis method. Most service and IT industries, construction, and light industries in manufacturing are included in the first quadrant group, whereas heavy and chemical industries are placed in the fourth quadrant since their power indices in the asset-oriented system are comparatively smaller than those of other institutional sectors. Second, investments and savings, which are induced by the central bank, are calculated for monetary policy evaluations. Industries are bifurcated into two groups to compare their features. The first group refers to industries whose power of dispersion in the asset-oriented system is greater than 1, whereas the second group indicates that their index is less than 1. We found that the net induced investments (NII)–total liabilities ratios of the first group show levels half those of the second group since the former's induced savings are obviously greater than the latter.

Computational Evaluation of Wind Loads on Low- and High- Rise Buildings

Buildings and other infrastructures located in the coastal regions of the US have a higher level of wind vulnerability. Reducing the increasing property losses and causalities associated with severe windstorms has been the central research focus of the wind engineering community. The present wind engineering toolbox consists of building codes and standards, laboratory experiments, and field measurements. The American Society of Civil Engineers (ASCE) 7 standard provides wind loads only for buildings with common shapes. For complex cases it refers to physical modeling. Although this option can be economically viable for large projects, it is not cost-effective for low-rise residential houses. To circumvent these limitations, a numerical approach based on the techniques of Computational Fluid Dynamics (CFD) has been developed. The recent advance in computing technology and significant developments in turbulence modeling is making numerical evaluation of wind effects a more affordable approach. The present study targeted those cases that are not addressed by the standards. These include wind loads on complex roofs for low-rise buildings, aerodynamics of tall buildings, and effects of complex surrounding buildings. Among all the turbulence models investigated, the large eddy simulation (LES) model performed the best in predicting wind loads. The application of a spatially evolving time-dependent wind velocity field with the relevant turbulence structures at the inlet boundaries was found to be essential. All the results were compared and validated with experimental data. The study also revealed CFD’s unique flow visualization and aerodynamic data generation capabilities along with a better understanding of the complex three-dimensional aerodynamics of wind-structure interactions. With the proper modeling that realistically represents the actual turbulent atmospheric boundary layer flow, CFD can offer an economical alternative to the existing wind engineering tools. CFD’s easy accessibility is expected to transform the practice of structural design for wind, resulting in more wind-resilient and sustainable systems by encouraging optimal aerodynamic and sustainable structural/building design. Thus, this method will help ensure public safety and reduce economic losses due to wind perils.

Le processus décisionnel sous-jacent à la rétroaction corrective des enseignants de français langue seconde à l'oral

L’objectif de cette étude qualitative est de décrire et de comprendre le processus décisionnel sous-jacent à la rétroaction corrective d’un enseignant de langue seconde à l’oral. Pour ce faire, elle décrit les principaux facteurs qui influencent la décision de procéder à une rétroaction corrective ainsi que ceux qui sous-tendent le choix d’une technique de rétroaction particulière. Trois enseignantes de français langue seconde auprès d’un public d’adultes immigrants au Canada ont participé à cette recherche. Des séquences complètes d’enseignement ont été filmées puis présentées aux participantes qui ont commenté leur pratique. L’entretien de verbalisation s’est effectué sous la forme d’un rappel stimulé et d’une entrevue. Cet entretien constitue les données de cette étude. Les résultats ont révélé que la rétroaction corrective ainsi que le choix de la technique employée étaient influencés par des facteurs relatifs à l’erreur, à l’apprenant, au curriculum, à l’enseignant et aux caractéristiques des techniques. Ils ont également révélé que l’apprenant est au cœur du processus décisionnel rétroactif des enseignants de langue seconde. En effet, les participantes ont affirmé vouloir s’adapter à son fonctionnement cognitif, à son état affectif, à son niveau de langue et à la récurrence de ses erreurs. L’objectif de cette étude est d’enrichir le domaine de la formation initiale et continue des enseignants de L2. Pour cela, des implications pédagogiques ont été envisagées et la recommandation a été faite de porter à la connaissance des enseignants de L2 les résultats des recherches sur l’efficacité des techniques de rétroaction corrective, particulièrement celles qui prennent en compte les caractéristiques des apprenants.

Feeling existentially touched - A phenomenological notion of the well-being of elderly living in special housing accommodation from the perspective of care professionals

This article presents a phenomenological analysis of interview material, in which 12 care professionals in elderly care reflect on the elderly's well-being within the frame of special housing accommodation. The perspective of the care professionals is of special interest. The findings show that the well-being is characterized as the elderly's feelings of being existentially touched. The well-being is an existential experience of being acknowledged as a human being and is an approach that classifies the elderly's needs as those of having, loving, and being. The meaning of the phenomenon is elucidated by the constituents: (1) to feel the freedom of choice, (2) to feel pleasure, and (3) to feel closeness to someone or something. The findings contribute new understanding of well-being in the elderly care by its existential dimension of the well-being as "just being'' and of doing things in order to experience meaningfulness. Accordingly, the well-being of the elderly as it is seen from the perspective of the care professionals involves both carers' subjectivity and intersubjectivity between the care professional and the elderly. An implication for promoting elderly's well-being is to develop awareness of these existential dimensions.
