The design of optimal education policies when individuals differ in inherited wealth and ability

In this paper I consider the role of education poli-cies in redistribution of income when individuals differ in two aspects: ability and inherited wealth. I discuss the extent to which the rules that emerge in unidimensional settings apply also in the bidimen-sional setting considered in this paper. The main conclusion is that, subject to some qualifi cations, the same type of rules that determine optimal education policies when only ability heterogeneity is considered apply to the case where both parameters of heterogeneity are considered. The qualifi cations pertain to the implementation of the optimal alloca-tion of resources to education and not the way the optimal allocations fi rst- and second-best differ.

Naar verantwoorde zelfregulatie in opvoeding, onderwijs en diagnostiek.

De beoordeling van vorderingen en inzet van (extra) diagnostiek ('indicatiestelling') in het onderwijs kunnen de kans op het ontstaan van problemen bij een kind vergroten. Tijdige herkenning en preventieve ondervanging van de problemen vragen veranderingen in de inhoudelijke, evaluatieve, didactisch-organisatorische en diagnostische systematieken in en rond scholen. Daarom wordt gewerkt aan de opbouw van een inhoudelijk integrerende, pedagogisch-didactische kernstructuur (PDKS). Deze helpt de dialoog en samenwerking tussen opvoedeling(en) of leerling(en), opvoeder(s), leerkracht(en) en andere professionals eenduidig in te richten en te optimaliseren. Didactisch-organisatorische steun wordt verleend door passende software in de vorm van 'Diagnostische, Instructie en Management Systemen' (DIMS). De beoogde veranderingen worden samen met leerkrachten en schoolleidingen ontwikkeld en proefondervindelijk gerealiseerd in enkele scholen voor primair onderwijs. De schoolontwikkeling biedt de contextuele condities ter realisatie van 'verantwoorde zelfregulatie' van elk kind of elke leerling. Dit wordt toegelicht in verschillende praktijkvoorbeelden. Ook worden volgende ontwikkelingen geschetst.

‘Optimaliserend Onderwijs’ voor elke leerling. Multiniveau theoretisch ontwerp en praktijkontwikkeling

Een review van onderwijsanalyses en (beleids)onderzoeken verricht in de periode 1916-2015 wijst uit dat de reguliere jaarklassensystematiek in het Nederlandse primair en voortgezet onderwijs aanleiding geeft tot prestatie- en motivatieproblemen bij risico-leerlingen. Dit zijn met name de leerlingen die qua ontwikkelingspotenties of leervorderingen (aanvankelijk) duidelijk naar beneden of naar boven afwijken van leeftijdsgenoten in een groep of klas. Ondervanging van deze problemen lijkt mogelijk via een preventieve systematiek van ‘Optimaliserend Onderwijs’ voor elk kind in de vóór- of vroegschoolse educatie en elke leerling in het primair of voortgezet onderwijs. Een eerste vraag betreft de inhoudelijke en vormgevingskenmerken van dit onderwijsontwerp: welke richtlijnen en specificaties daarvan kunnen het onderwijs, spelen en leren voor elke leerling, zo optimaal mogelijk inhoud en vorm geven en hoe ziet een model van dit Optimaliserend Onderwijs eruit? Een tweede vraag is gericht op de realisatie van dit onderwijsontwerp: hoe is deze onderwijssystematiek te ontwikkelen in de Nederlandse schoolpraktijk? Gebruik van de sneeuwbalmethode in met name Nederlandse onderzoeks- en designliteratuur leidt tot beantwoording van de eerste vraag in de vorm van een multiniveau theoretisch ontwerp van ‘Optimaliserend Onderwijs’. Kernpunten hierin zijn: landelijke (deel)curricula gekenmerkt door instructievarianten; integratie van dubbele diagnostiek (individueel-longitudinaal en vergelijkend-genormeerd); flexibele certificerings- en diplomeringsstructuur; een ondersteunende schoolorganisatie; gecontroleerde opbrengst-optimalisering per kind of leerling en op instellings- en schoolniveau; per vóór- of vroegschoolse instelling of school(bestuur) kunnen ook vrije ofwel eigen onderwijsinvullingen worden ingericht. Beantwoording van de tweede vraag gebeurt met behulp van (onderzoeks)literatuur over multiniveau onderwijsinnovatie in de schoolpraktijk. Aanbevolen wordt om, op basis van een gezamenlijk besluit van het ministerie van Onderwijs, Cultuur en Wetenschap, de Tweede Kamer, relevante onderwijsinstanties, schoolbesturen en ouderorganisaties, te komen tot inrichting van samenhangende ontwikkelingsprojecten en -onderzoeken. Via een projectenserie in instellingen voor vóór- of vroegschoolse educatie en scholen voor primair en voortgezet onderwijs kan gecontroleerd worden samengewerkt tussen leid(st)ers, leerkrachten en docenten, scholen, ontwikkelings- en andere onderwijsinstellingen, instellingen voor onderzoek en informatietechnologie, en onderwijspolitiek. Tussenresultaten van Optimaliserend Onderwijs worden steeds in andere instellingen en scholen beproefd en verder verspreid.

Learning for self-regulation: Improving instructional benefits for pupils, teachers, parents, schools, and society at large

Compulsory education laws oblige primary and secondary schools to give each pupil positive encouragement in, for example, social, emotional, cognitive, creative, and ethical respects. This is a fairly smooth process for most pupils, but it is not as easy to achieve with others. A pattern of pupil, home or family, and school variables turns out to be responsible for a long-term process that may lead to a pupil’s dropping out of education. A systemic approach will do much to introduce more clarity into the diagnosis, potential reduction and possible prevention of some persistent educational problems that express themselves in related phenomena, for example low school motivation and achievement; forced underachievement of high ability pupils; concentration of bullying and violent behaviour in and around some types of classes and schools; and drop-out percentages that are relatively constant across time. Such problems have a negative effect on pupils, teachers, parents, schools, and society alike. In this address, I would therefore like to clarify some of the systemic causes and processes that we have identified between specific educational and pupil characteristics. Both theory and practice can assist in developing, implementing, and checking better learning methods and coaching procedures, particularly for pupils at risk. This development approach will take time and require co-ordination, but it will result in much better processes and outcomes than we are used to. First, I will diagnose some systemic aspects of education that do not seem to optimise the learning processes and school careers of some types of pupils in particular. Second, I will specify cognitive, social, motivational, and self-regulative aspects of learning tasks and relate corresponding learning processes to relevant instructional and wider educational contexts. I will elaborate these theoretical notions into an educational design with systemic instructional guidelines and multilevel procedures that may improve learning processes for different types of pupils. Internet-based Information and Communication Technology, or ICT, also plays a major role here. Third, I will report on concrete developments made in prototype research and trials. The development process concerns ICT-based differentiation of learning materials and procedures, and ICT-based strategies to improve pupil development and learning. Fourth, I will focus on the experience gained in primary and secondary educational practice with respect to implementation. We can learn much from such practical experience, in particular about the conditions for developing and implementing the necessary changes in and around schools. Finally, I will propose future research. As I hope to make clear, theory-based development and implementation research can join forces with systemic innovation and differentiated assessment in educational practice, to pave the way for optimal “learning for self-regulation” for pupils, teachers, parents, schools, and society at large.

La construction de relations de confiance au sein des équipes-écoles d’établissements en milieu autochtone du Québec selon les perceptions de leur direction

Résumé : La gestion des ressources humaines dans les écoles situées au sein de communautés autochtones est marquée par différents enjeux d’ordres social, culturel, ethnoculturel, économique et administratif qui impactent les pratiques de leurs directions. Ceux-ci touchent à tous les aspects de la gestion des écoles et peuvent être révélateurs d’un malaise dans l’encadrement des actrices et des acteurs à travers des structures administratives, juridiques, éducatives ou de gouvernance qui comportent des défis relationnels et interactionnels majeurs. Ce type de malaise peut moduler les actions des actrices et des acteurs des établissements et peut entrainer des impacts dans leurs relations, notamment au niveau de leurs relations de confiance, essentielles à la qualité de leurs actions communes. L’approfondissement de cette problématique porte essentiellement sur les conditions associées à la construction de la confiance qui sont de différents ordres, c’est-à-dire contextuel, institutionnel, organisationnel, relationnel ou individuel. Utilisant une approche qualitative, cette recherche repose sur vingt-trois entrevues semi-dirigées avec des directions d’établissement provenant de dix-sept communautés et de trois nations autochtones différentes. L’analyse est menée à partir d’une approche exploratoire constructiviste et interprétativiste. Les conclusions permettent de dégager que la construction de relations de confiance entre des actrices et des acteurs sont tributaires de conditions dans lesquelles s’inscrivent des dynamiques interactionnelles particulières. Influencées par le contexte autochtone singulier, ces conditions sont préalables aux actrices et aux acteurs ou associées à leurs comportements, attitudes, actions ou pratiques. Il apparait que ces dynamiques s’inscrivent dans une configuration des équipes-écoles se caractérisant par six catégories-types d’individus qui se déclinent selon leur origine et leur appartenance ou leur identité ethnique, à savoir les voyageurs autochtones et allochtones, les étrangers autochtones et allochtones et les natifs autochtones et allochtones. La meilleure compréhension de cette organisation conduit à une conception large de la configuration des dynamiques interactionnelles entre des individus et des groupes et entre des communautés d’individus. Ces individus s’affilient spécifiquement selon des identités ou des appartenances individuelles ou de groupe qui peuvent être de différents ordres soit particulièrement, mais non exclusivement, ethnique, linguistique, familial ou se rapportant à des croyances particulières.

Education, preferences for leisure, and the optimal income tax schedule

Recent advances in dynamic Mirrlees economies have incorporated the treatment of human capital investments as an important dimension of government policy. This paper adds to this literature by considering a two period economy where agents are di erentiated by their preferences for leisure and their productivity, both private information. The fact that productivity is only learnt later in an agent's life introduces uncertainty to agent's savings and human capital choices and makes optimal the use of multi-period tie-ins in the mechanism that characterizes the government policy. We show that optimal policies are often interim ine cient and that the introduction of these ine ciencies may take the form of marginal tax rates on labor income of varying sign and educational policies that include the discouragement of human capital acquisition. With regards to implementation, state-dependent linear taxes implement optimal savings, while human capital policies may require labor income taxes that depend directly on agents' schooling.

Optimal design of periodic functionally graded composites with prescribed properties

The computational design of a composite where the properties of its constituents change gradually within a unit cell can be successfully achieved by means of a material design method that combines topology optimization with homogenization. This is an iterative numerical method, which leads to changes in the composite material unit cell until desired properties (or performance) are obtained. Such method has been applied to several types of materials in the last few years. In this work, the objective is to extend the material design method to obtain functionally graded material architectures, i.e. materials that are graded at the local level (e.g. microstructural level). Consistent with this goal, a continuum distribution of the design variable inside the finite element domain is considered to represent a fully continuous material variation during the design process. Thus the topology optimization naturally leads to a smoothly graded material system. To illustrate the theoretical and numerical approaches, numerical examples are provided. The homogenization method is verified by considering one-dimensional material gradation profiles for which analytical solutions for the effective elastic properties are available. The verification of the homogenization method is extended to two dimensions considering a trigonometric material gradation, and a material variation with discontinuous derivatives. These are also used as benchmark examples to verify the optimization method for functionally graded material cell design. Finally the influence of material gradation on extreme materials is investigated, which includes materials with near-zero shear modulus, and materials with negative Poisson`s ratio.

The nurse lecturer role in clinical practice conceptualized: helping clinical teachers provide optimal student learning

Despite the fairly wide reporting in the literature of the ma ny roles of clinical supervision by the nursing teacher, little attention has been given to conceptualizing the relative priorities these roles take during the process of supervising nursing students in clinical practice. The purpose of this paper is to consider the manifestations and implications of conflicting roles when nurse lecturers undertake clinical supervision. Previously published research will provide working examples of issues in a conceptual framework for clinical teaching.

Graduating 4th year radiology residents' perception of optimal imaging modalities for neoplasm and trauma: a pilot study from four U.S. universities

OBJECTIVE: Our purpose was to assess 4th year radiology residents' perception of the optimal imaging modality to investigate neoplasm and trauma. MATERIALS AND METHODS: Twenty-seven 4th year radiology residents from four residency programs were surveyed. They were asked about the best imaging modality to evaluate the brain and spine, lungs, abdomen, and the musculoskeletal system. Imaging modalities available were MRI, CT, ultrasound, PET, and X-ray. All findings were compared to the ACR appropriateness criteria. RESULTS: MRI was chosen as the best imaging modality to evaluate brain, spine, abdominal, and musculoskeletal neoplasm in 96.3%, 100%, 70.4%, and 63% of residents, respectively. CT was chosen by 88.9% to evaluate neoplasm of the lung. Optimal imaging modality to evaluate trauma was CT for brain injuries (100%), spine (92.6%), lung (96.3%), abdomen (92.6%), and major musculoskeletal trauma (74.1%); MRI was chosen for sports injury (96.3%). There was agreement with ACR appropriateness criteria. CONCLUSION: Residents' perception of the best imaging modalities for neoplasm and trauma concurred with the appropriateness criteria by the ACR.

Implementing the OPTIMAL model : the impact on students' motivation in an elementary school games environment

Optimal challenge occurs when an individual perceives the challenge of the task to be equaled or matched by his or her own skill level (Csikszentmihalyi, 1990). The purpose of this study was to test the impact of the OPTIMAL model on physical education students' motivation and perceptions of optimal challenge across four games categories (i. e. target, batting/fielding, net/wall, invasion). Enjoyment, competence, student goal orientation and activity level were examined in relation to the OPTIMAL model. A total of 22 (17 M; 5 F) students and their parents provided informed consent to take part in the study and were taught four OPTIMAL lessons and four non-OPTIMAL lessons ranging across the four different games categories by their own teacher. All students completed the Task and Ego in Sport Questionnaire (TEOSQ; Duda & Whitehead, 1998), the Intrinsic Motivation Inventory (IMI; McAuley, Duncan, & Tanmien, 1987) and the Children's Perception of Optimal Challenge Instrument (CPOCI; Mandigo, 2001). Sixteen students (two each lesson) were observed by using the System for Observing Fitness Instruction Time tool (SOFTT; McKenzie, 2002). As well, they participated in a structured interview which took place after each lesson was completed. Quantitative results concluded that no overall significant difference was found in motivational outcomes when comparing OPTIMAL and non-OPTIMAL lessons. However, when the lessons were broken down into games categories, significant differences emerged. Levels of perceived competence were found to be higher in non-OPTIMAL batting/fielding lessons compared to OPTIMAL lessons, whereas levels of enjoyment and perceived competence were found to be higher in OPTIMAL invasion lessons in comparison to non-OPTIMAL invasion lessons. Qualitative results revealed significance in feehngs of skill/challenge balance, enjoyment and competence in the OPTIMAL lessons. Moreover, a significance of practically twice the active movement time percentage was found in OPTIMAL lessons in comparison to non-OPTIMAL lessons.
