Implementation of project based learning in a training package context

Wright, Julie, j.wright@rmit.edu.au January 2008 (has links)
Training Packages form the basis upon which practitioners in the Vocational Education and Training (VET) sector in Australia develop their pedagogical processes. As workplaces adapt their practices to compete globally, demand for skilled and knowledgeable workers places pressure on institutional training providers such as TAFE to develop training programs that support the acquisition of higher order thinking skills in graduates. Using a competence based framework as a backdrop, the research centres on the notion of the place of Project Based Learning in a Training Package context. The research proposes that learning through projects is an effective means of integrating Training Package outcomes with an instructional model that engages learners in independent, flexible and reflective learning. The research was conducted retrospectively from a case study of an AQF Level 6 Textile, Clothing and Footwear Training Package Program at RMIT University TAFE. An Action Research approach underpins the investigation, resulting in the profiling of teaching, learning and assessment as areas in need of further examination. These defining themes are explored in the context of the Project Based Learning model developed at RMIT, with consideration given to the potential for broader application. The discussion concludes with a theoretical review of the new understandings of pedagogy. The study aims to establish that a constructive alignment exists between the behaviourist approach of Training Packages and the more constructivist theories behind Project Based Learning; rendering it a suitable instructional model that meets the needs of 21st century learners.

Computational Studies of the Effects of Active and Passive Circulation Enhancement Concepts on Wind Turbine Performance

Tongchitpakdee, Chanin 14 June 2007 (has links)
With the advantage of modern high speed computers, there has been an increased interest in the use of first-principles based computational approaches for the aerodynamic modeling of horizontal axis wind turbine (HAWT). Since these approaches are based on the laws of conservation (mass, momentum, and energy), they can capture much of the physics in great detail. The ability to accurately predict the airloads and power output can greatly aid the designers in tailoring the aerodynamic and aeroelastic features of the configuration. First-principles based analyses are also valuable for developing active means (e.g., circulation control), and passive means (e.g., Gurney flaps) of reducing unsteady blade loads, mitigating stall, and for efficient capture of wind energy leading to more electrical power generation. In this present study, the aerodynamic performance of a wind turbine rotor equipped with circulation enhancement technology (trailing edge blowing or Gurney flaps) is investigated using a three-dimensional unsteady viscous flow analysis. The National Renewable Energy Laboratory (NREL) Phase VI horizontal axis wind turbine is chosen as the baseline configuration. Prior to its use in exploring these concepts, the flow solver is validated with the experimental data for the baseline case under yawed flow conditions. Results presented include radial distribution of normal and tangential forces, shaft torque, root flap moment, surface pressure distributions at selected radial locations, and power output. Results show that good agreement has been for a range of wind speeds and yaw angles, where the flow is attached. At high wind speeds, however, where the flow is fully separated, it was found that the fundamental assumptions behind this present methodology breaks down for the baseline turbulence model (Spalart-Allmaras model), giving less accurate results. With the implementation of advanced turbulence model, Spalart-Allmaras Detached Eddy Simulation (SA-DES), the accuracy of the results at high wind speeds are improved. Results of circulation enhancement concepts show that, at low wind speed (attached flow) conditions, a Coanda jet at the trailing edge of the rotor blade is effective at increasing circulation resulting in an increase of lift and the chordwise thrust force. This leads to an increased amount of net power generation compared to the baseline configuration for moderate blowing coefficients. The effects of jet slot height and pulsed jet are also investigated in this study. A passive Gurney flap was found to increase the bound circulation and produce increased power in a manner similar to the Coanda jet. At high wind speed where the flow is separated, both the Coanda jet and Gurney flap become ineffective. Results of leading edge blowing indicate that a leading edge blowing jet is found to be beneficial in increasing power generation at high wind speeds. The effect of Gurney flap angle is also studied. Gurney flap angle has significant influence in power generation. Higher power output is obtained at higher flap angles.

田揚名 Unknown Date (has links)
2005年天下雜誌製造業一千大資料顯示,國內企業總部有四成比例分佈在台北都會區,而近年來新竹科學園區的崛起對台灣經濟發展有其不可忽視的力量,而其形塑帶來新的產業空間意象(知名地域品牌)、高科技產業群聚以及產業網絡發展更進一步帶動周邊廠商或總部在新竹縣市聚集。 回顧近代區位選擇理論及企業總部相關文獻,指出生產性服務業及創新氛圍對製造業總部在地理空間區位選擇具有關鍵性的影響;並透過觀察臺灣地區各縣市企業總部分佈情形及兩岸分工的現況分析,藉由logist統計分析並以深入訪談方式確認企業設置總部區位分佈因素,提出以下結論:觀察發現製造業企業總部空間分佈差異性頗大,其中制度因素透過統計分析結果證實會對企業總部區位分佈產生影響,尤其是大廠在總部區位分佈上比較偏好工業地域(台北及新竹縣市)。 在兩岸專業分工方面,形成特定地域擁有科技產業群聚,並可發現其地理空間分佈以新竹科學園區、南港軟體園區及內湖科技園區為主,前兩者為制度下的產物,而後者則為民間自主力量,由內湖科技園區、南港軟體園區以及新竹科學園區,以及北部地區充足的知識設施及產、官、學界共同建構出的創新氛圍確實影響企業總部區位分佈。 企業總部主要是組織上指揮系統的概念,總部提供各子公司所需要的技術、資金、行銷策略和在地化的配套措施,近年國內製造業廠商大量出走對岸,導致國內產業及組織發生結構性的改變,基於國際化競爭及全球化佈局之際,企業如何調適與轉型即成為未來生存的關鍵所在。建議政府未來持續培育優質研發環境及高素質人力資源,持續強化創新氛圍塑造產業發展優質環境。 / According to the 1,000 major manufacturing industry in Taiwan,’ 40% of domestic enterprise headquarters are located in the Taipei metropolis. In recent years, the emergence of Hsinchu Science Park shows strength of economic development in Taiwan. This strength further moulds and brings the new industry space image (famous region brand), the industry cluster, as well as the development of industry network. Moreover, these factors drive related manufacturer or general headquarters to assemble in Hsinchu. Reviews of modern position theory and general headquarters point out that the productive service industry and innovative atmosphere have critical influence on sing geographical space position for the manufacturing industry. This study observes the general headquarters of enterprises of all counties and cities in Taiwan; By using logist statistical analysis and the interview method to confirm distribution factors of general headquarters position, this study propose the following conclusions. There is great difference in the space distribution of general headquarters between manufacturing industry enterprises. Among them, the statistical analysis confirms that the factor of system has influence on the position of enterprises general headquarters. Especially, as far as the general headquarters location is concerned, big factories have preference for choosing industrial regions. For the part of division among specialized deartments of two sides, clusters of scientific and technological industry, which form specific regions, are located mainly in Hsinchu Science Park, Nankang Software Park, and Neihu Technology Park. The first two parks are products of government systems, while the third one is established by independent strength of private companies. It is showed that the innovative atmosphere, which is composed of the above three parks and sufficient knowledge facilities in northern Taiwan, indeed influences locations of enterprises general headquarters. The general headquarters of enterprises are mainly the concept of the command system in an organization. It is suggested that the government should keep cultivate research/development environment and high quality human resources, and strength innovative atmosphere to mould better industry environments in the future.

Eigenverantwortung und Verhandlungsautonomie für innovatives und gesundes Arbeitshandeln

Hüttges, Annett 23 December 2010 (has links) (PDF)
Die vorliegende Arbeit untersucht die Relevanz von Merkmalen psychologischer Verträge und organisationaler Demokratie, Basisdimensionen psychischer Arbeitsanforderungen und Eigenverantwortung als Determinanten für Gesundheit, Arbeitsengagement und Innovation bei flexibilisierter Wissensarbeit. Dabei knüpft sie an der Frage an, welchen Erklärungswert indirekte Kontrollmechanismen auf organisationaler Ebene für die widersprüchliche Befundlage bei eigenverantwortlich handelnden Beschäftigten haben. Dazu wird das Konzept der Verhandlungsautonomie (Moldaschl, 2001) als organisationale Kontrolle von Beschäftigten über ihre Arbeits- und Beschäftigungsbedingungen vorgestellt, operationalisiert und in seiner strukturellen Invarianz bestätigt. Die empirischen Ergebnisse weisen ferner auf die inkrementelle Validität des Konstruktes hin, da Verhandlungsautonomie einen substanziellen zusätzlichen Beitrag zur Varianzaufklärung von Innovation und Gesundheit bei Wissensarbeit leistet, der über Personen- und Tätigkeitsmerkmale hinausgeht. Im Mittelpunkt der Arbeit steht die Überprüfung eines theoretisch begründeten Wirkungsmodells, in dem Eigenverantwortung als personale Ressource und Verhandlungsautonomie als organisationale Ressource wechselseitig aufeinander bezogene Determinanten für Stresserleben, Arbeitsengagement und innovatives Arbeitshandeln darstellen. Die Ergebnisse verweisen auf die Bedeutung von Eigenverantwortung und Verhandlungsautonomie als Innovations- und Gesundheitsressourcen, um Widersprüche zwischen leistungs- und gesundheitsbezogenen Zielen in Organisationen zu reduzieren, indem sie einer progressiven Entwicklung chronischer arbeitsbezogener Stresszustände im Innovationsgeschehen entgegen wirken. Damit eröffnen sich für Organisationen Handlungsperspektiven, durch Stärkung organisationaler Demokratie einerseits und Unterstützung eigenverantwortlichen Arbeitshandelns mit einer breiten Auslegung individueller Arbeitsrollen andererseits das Entstehen von Innovationen unter salutogenen Bedingungen zu befördern.

Fukttillstånd i olika ytterväggar med tre olika fasadsystem : En parameterstudie med Wufi / Moisture conditions in different exterior walls with three different façade systems : A parameter study with Wufi

Augustsson, Andreas, Adolfsson, Kristian January 2015 (has links)
Ett stort antal av miljonprogrammets byggnader är idag i behov av renovering. Då många av dessa byggnader har en hög energiförbrukning kan det vara lönsamt att samtidigt energieffektivisera byggnaderna, bland annat genom tilläggsisolering. Det är av stor vikt att noggrant undersöka hur byggnaderna påverkas ur fukthänsyn innan nya fasadsystem tas i bruk för att undvika framtida fuktrelaterade skador.Syftet är att undersöka tre fasadsystem utifrån hur olika fuktbelastningar, väderstreck, tilläggsisoleringar och stommaterial påverkar ytterväggars fukttillstånd och risken för mikrobiell tillväxt. Även hur väl de olika fasadsystemen lämpar sig för att uppföras på en befintlig stomme i trä-, lättbetong- och betongstomme har undersökts. För att undersöka detta har fuktsimuleringar gjorts i fuktberäkningsprogrammet Wufi och resultaten har analyserats genom jämförelse av RF-kurvor samt riskbedömning för mögeltillväxt i Wufi Bio.En övergripande slutsats är bland annat att inläckage av slagregn är en stor belastning för fasadsystemen. Systemens fuktsäkerhet beror till stor del på dess förmåga att hantera inläckaget.Studien visar även att en fungerande ventilerad luftspalt, en god dränerande funktion eller en konstruktion med genomgående relativt ångöppna material har förmågan att hantera inläckage av slagregn effektivt. / A large number of buildings built under “miljonprogrammet” is today in need of renovation. With their high energy consumption it is also considered profitable to improve the buildings energy efficiency e.g. by additional insulation. It is however important to thoroughly evaluate potential damp issues that might arise as a result of these improvements before starting to implement a new building exterior.The aim of this study was to investigate three different façade systems based on how their moisture content and risk for mould growth are affected by different moisture loads, orientation, and additional insulation. Included is also a performance evaluation for each building exterior solution mounted on existing structure of wood, lightweight concrete and concrete structure. Damp simulations were done with the program Wufi and the results were then analysed by comparison to RF-curves in combination with risk assessments of the growth of mould with “Wufi Bio”.The overall conclusion shows that leakage due to torrential rain poses a great strain on building exterior systems. A solutions damp proof quality is largely dependent on its ability to withstand leakage from outer sources.The study also shows that a well ventilated cavity wall, sufficient drainage or a construction of exclusively vapour open materials has a positive impact on the amount of leakage.

Δόσης, Σωτήρης 26 August 2014 (has links)
Στόχος της παρούσας διατριβής είναι η σχεδίαση και η αξιολόγηση μιας διδακτικής ακολουθίας για την κίνηση του απλού εκκρεμούς, στα πλαίσια της καινοτομικής και εποικοδομητικής αντίληψης για το αναλυτικό πρόγραμμα Φυσικών Επιστημών. Πρόκειται για έρευνα εφικτότητας η οποία διενεργείται σε τρία επίπεδα: της ανάλυσης, του σχεδιασμού και της εφαρμογής. Το επίπεδο ανάλυσης περιλαμβάνει την επιστημολογική ανάλυση του Γαλιλαϊκού πλαισίου μελέτης της κίνησης του απλού εκκρεμούς, την ανάλυση των νοητικών παραστάσεων των μαθητών για την κίνηση του απλού εκκρεμούς και την ανάλυση των απαιτήσεων της καινοτομικής και εποικοδομητικής αντίληψης για το αναλυτικό πρόγραμμα Φυσικών Επιστημών. Το επίπεδο σχεδιασμού περιλαμβάνει τη διατύπωση των διδακτικών στόχων και τη διαμόρφωση του περιεχομένου της διδακτικής ακολουθίας. Δομικά χαρακτηριστικά της ακολουθίας συνιστούν (α) η πολιτισμική επιλογή του τεχνολογικού πλαισίου λειτουργίας του ρολογιού-εκκρεμούς, (β) η εννοιολογική επιλογή της Γαλιλαϊκής προσέγγισης της μελέτης του απλού εκκρεμούς και (γ) η μεθοδολογική επιλογή της σχολικής εκδοχής της υποθετικο -παραγωγικής προσέγγισης της επιστημονικής γνώσης. Η προτεινόμενη ακολουθία απαρτίζεται από τέσσερις διδακτικές ενότητες και υλοποιείται μέσω δραστηριοτήτων - προβλημάτων, οι οποίες βασίζονται σε μετασχηματισμένο ή αυθεντικό υλικό προερχόμενο από την Ιστορία της Επιστήμης. Το επίπεδο εφαρμογής περιλαμβάνει την πειραματική εφαρμογή της διδακτικής ακολουθίας σε 36 μαθητές της Γ΄ Γυμνασίου και την αξιολόγηση της γνωστικής προόδου που υποθέτουμε ότι θα σημειώσουν. Χρησιμοποιείται η τεχνική του ερωτηματολογίου για να ανιχνευθούν οι νοητικές παραστάσεις των μαθητών πριν και μετά τη συμμετοχή τους στην εφαρμογή του προγράμματος. Η ανάλυση των δεδομένων πραγματοποιείται σε τρία επίπεδα. Στο πρώτο επίπεδο καταδεικνύεται η θετική συμβολή των δραστηριοτήτων της διδακτικής ακολουθίας στη μετακίνηση των απαντήσεων των μαθητών προς την κατεύθυνση της αποδεκτής σχολικής γνώσης για τη κίνηση του εκκρεμούς. Στο δεύτερο επίπεδο καταδεικνύεται η συνολική σημαντική γνωστική πρόοδος των μαθητών στις τρεις συνιστώσες της επιστημονικής γνώσης, την πολιτισμική, την εννοιολογική και τη μεθοδολογική. Τέλος, στο τρίτο επίπεδο καταδεικνύεται η θετική συμβολή της διδακτικής ακολουθίας στη συγκρότηση ομάδων μαθητών που χρησιμοποιούν με επαρκή και συνεκτικό τρόπο τόσο την εννοιολογική όσο και τη μεθοδολογική συνιστώσα της επιστημονικής γνώσης. / The aim of this thesis is the design and evaluation of a teaching sequence for the motion of the simple pendulum, under the innovative and constructive approach of the science curriculum. This study belongs to the ‘feasibility’ research current and was carried out at three levels: analysis, design and implementation. The level of analysis involves the analysis of Galilean epistemological framework about the motion of the pendulum, the analysis of mental representations of students about the motion of the simple pendulum and the analysis of the requirements of innovative and constructive approaches for the science curriculum. The level of design includes the formulation of learning objectives and the content development of the teaching sequence. The structural features of the sequence concern (a) the cultural dimension of scientific knowledge (the relationship between the simple pendulum and the timekeeping problem), (b) the conceptual dimension of scientific knowledge (a Galilean semi-quantitative approach of the isochronal motion of the simple pendulum) and (c) the methodological dimension of scientific knowledge (a hypothetico-deductive approach of the relation between the period of the simple pendulum, its string length and its gravitational acceleration) The proposed sequence is composed of four modules and is implemented through problem – solving activities, which are based on transformed or authentic material from the History of Science. The application level includes the experimental implementation of the teaching sequence to 36 students aged 14-15 y.o. and the evaluation of their cognitive progress that we assume took place during the teaching. A questionnaire is used to detect mental representations of students before and after having participated in the teaching intervention. Data analysis was carried out on three levels. The first level shows the positive contribution of the activities of the teaching sequence to a transformation of student responses towards the acceptable scientific school knowledge about the motion of the simple pendulum. The second level shows the overall significant cognitive progress of students in the three components of scientific knowledge, cultural, conceptual and methodological. Finally, the third level shows the positive contribution of the teaching sequence in the formation of groups of pupils using in an efficient and coherent manner both conceptual and methodological aspects of scientific knowledge.
