Managing learner aggression in rural secondary schools in the Empangeni District of KwaZulu-Natal

Singh, Gunam Dolan 06 1900 (has links)
The aim of this study was to investigate the causes and consequences of learner aggression in rural secondary schools in the Empangeni District of KwaZulu-Natal. The study also sought to establish the management strategies required to manage learner aggression in rural secondary schools. An in-depth literature study was conducted in this regard. A qualitative research design and methodology was adopted to investigate the phenomenon through an interview process with participants from five rural secondary schools. This study found that the causes of learner aggression were rooted in the family, the environment and the school. It was further established that the consequences of learner aggression were so serious that it resulted in victims experiencing intense fear, anxiety, tension, depression and ill-health. Furthermore, the findings of the empirical investigation concurred, to a large extent, with the findings of the literature study. Based on these findings, recommendations were made regarding the management of learner aggression in rural secondary schools. / Educational Leadership and Management / M. Ed. (Education Management)

The mission of the local church amidst social disruption and transition : a study of the Ilitha and Ndevana communities in the Eastern Cape

Odendaal, J. N. 01 1900 (has links)
The policy of Separate Development and its forceful implementation by the Nationalist Government from the !960's and into the 1980's resulted in the resettlement of thousands of Africans in the 'homeland' Ciskei in the Eastern Cape. All these changes had a profound and very often a disruptive influence on the lives of those involved. People's ability to survive amidst these circumstances, was tested to the limit. This study looks at the role of the local Christian faith community in supporting its members during these rapid and disruptive socioeconomic and political changes. The study is confined to two congregations of the Uniting Reformed Church in Southern Africa in Ilitha and Ndevana in the Eastern Cape. Following an introductory chapter, Chapter 2 gives a historical outline of developments in the broader Ciskei. Attention is also given to demographic, social and economic conditions. Chapter 3 describes the culture and feeling of despair, powerlessness and mistrust that is deeply entrenched in the minds of many people in the community due to depressive socio-economic situations. Chapter 4 gives an overview of the churches in the area and describes the supportive structures and actions of two churches in the Ilitha-Ndevana area. No instant solutions are offered to members but through mutual support they find a sense of belonging and encouragement in the midst of their hardship. In Chapter 5 a model for the mission of the local church in a context of social and economic change and disruption, is presented. It is shown how the image of Christianity and the Gospel have been distorted and misused in the past through the entanglement of mission and colonialism, a negative attitude towards African culture, and by contributing to the subordination of women in society. A vision that people in Africa can have peace and dignity and become self-reliant is proposed. Within the local faith community this vision is built on an understanding of God as the weak and suffering Lord, on fellowship and mutual support, a new reading of the Bible, a practical community based spirituality, and an emphasis on healing. / Die daarstelling en .kragdadige toepassing van die beleid van Afsonderlike Ontwikkeling vanaf die 1960's tot·die 1980's het tot gevolg_gehad dat duisende Swart Suid-AftilCaners hervestig is in die Ciskei-tuisland in die Oos-Kaap. Al hierdie veranderinge het verreikende en baie dikwels ontwrigtende gevolge op die betrokkenes gehad. Mense se vermoens om binne hierdie omstandighede te oorlee:t: is tot die uiterste beproef. Hierdie studie kyk na die rol van die plaaslike · Cbristelike. geloofsgemeenskap in die ondersteuning van sy lede tydens snelle en ontwrigtende sosiale, ekonomiese en politieke veranderinge. Die studie is beperk tot twee gemeentes van die Verenigende Gereformeerde Kerk in Suider-Aftika in Ilitha en Ndevana in die Oos-Kaap. Na 'n inleidende hoofstuk, gee hoofstuk 2 'n historiese oorsig van ontwikkelinge in die breere Ciskei-gebied. Aandag word ook gegee aan demografriese, sosiale en ekonomiese toestande. Hoofstuk 3 beskryf 'n kultuur en gevoel van moedeloosheid, magteloosheid en wantroue wat, as gevolg van neerdrukkende sosiaal-ekonomiese toestande, diep in menige mense se gemoedere vasgele is. Hoofstuk 4 gee 'n oorsig oor die kerke in die gebied en beskryf die ondersteunende strukture en optrede in twee gemeentes in die Ilitha-Ndevana area. Geen kitsoplossings word aan lede aangebied nie, maar deur onderlinge steun vind hulle geborgenheid en bemoediging te midde van swaarkry. In hoofstuk 5 word 'n model aangebied vir die missie van die plaaslike kerk te midde van sosiale en ekonomiese veranderinge en ontwrigting. Daar word aangetoon hoe die beeld van die Christendom in die verlede verwring en misbruik is deur: die verstrengeling van sending en kolonialisasie; 'n negatiewe houding teenoor kultuur in Afrika; en deur by te dra tot die ondergeskikte posisie van vroue in die samelewing. 'n Visie dat die mense van Afrika vrede en menswaardigheid kan geniet en self onderhoudend kan raak, word voorgestel. Binne die plaaslike geloofsgemeenskap word aan hierdie visie gebou deur 'n begrip van God as die magtelose en lydende Here, deur onderlinge gemeenskap en ondersteuning, 'n nuwe lees en begrip van die Bybel, 'n praktiese gemeenskaps-gerigte spiritualiteit en 'n beklemtoning van heling en herstel. / Christian Spirituality, Church History and Missiology / D.Th.

The impact of grade 10 learners' behaviour on their academic performance in mathematics

Hagoramagara, Franco 10 1900 (has links)
The aim of this study was to identify types of behaviour manifested by learners during mathematics instruction, and the impact that this behaviour might have on the mathematics performance of learners. The study was conducted in Far East cluster of Johannesburg East District, in the province of Gauteng, South Africa. At the time of the study the Far East cluster of Johannesburg East District consisted of a population of seven public high schools, of which two schools were randomly sampled to participate in the study. Participants consisted of (n=10) Grade 10 mathematics learners, 2 mathematics teachers and 2 heads of mathematics departments (HODs). Data from learners were collected using a set of their assessment scores accumulated over a period of six months, that is, from January 2014 to June 2014 (Section 1.3.3). Also, semi-structured interviews were carried out with learners to determine types of classroom behaviour they perceived to influence their mathematical performance. The aim of documenting learners‟ assessment scores (document analysis) was to determine their average performance in Grade 10 mathematics over a stipulated period. Teachers and HODs completed questionnaires to identify types of classroom behaviour that learners manifested during mathematics instruction. The study followed a qualitative approach with phenomenology research design (Section 3.2). The study identified several types of classroom behaviour that characterized mathematics instruction in both schools, such as making noise and not doing classwork and homework activities. In addition, the study established that forms of behavioural patterns that are manifested by learners during a mathematics instruction influenced their performance in the subject. Huitt‟s (1997) model was used to conceptualize and interpret the results. / Mathematics Education / M. Ed. (Mathematics Education)

Determinants of Intention to Use New Technology: An Investigation of Students in Higher Education

DuPree, Yolanda 01 January 2015 (has links)
The federal government continues to monitor the cost of paper texts as an essential component of postsecondary education expenses. The Higher Education Act (HEA), which was initially passed in 1965, was created to buttress the educational resources of colleges and universities. Along with addressing the benefits of financial aid in postsecondary and higher education, the act referenced the projected financial burdens of paper texts. The last 2008 reauthorization suggested that colleges and universities develop plans to reduce the costs of college. Congress is currently working to reauthorize the legislation. Based on this information, the problem identified in this study explored how to use the results of the study to develop a framework that may be used by universities. This framework could be used to consider the success (or failure) of the intention to use e-texts in student learning, given how the cost of textbooks contributes to the perceived high cost of college attendance. The primary goal of the study was to evaluate students’ perceptions of the usefulness of e-texts. The subordinate goal was to address the financial benefits of e-texts. In this study, the author has explored the perceived ease of use, perceived usefulness, and computer self-efficacy involved in the actual use of new technology such as textbooks in electronic format among undergraduate, postsecondary or university students. The main research questions for the study were: “How do the variables perceived ease of use, perceived usefulness, and computer self-efficacy impact the intention to use, which may be a predictor of actual use of new technology?” and “How will the results of this study assist institutions of higher education in planning for the successful acceptance of new technologies, which may or may not be a predictor of actual use?” The researcher used a Web-based survey and selected a sample of 5,600 undergraduate students from two universities. There were 482 complete responses to the survey. The context of the study included two traditional, land-based, universities. This was an exploratory, quantitative, qualitative research study. The research study measured the level of impact of perceived ease of use, perceived usefulness, and computer self-efficacy on the intention to use that may or may not lead to the actual use of new technology. The researcher investigated the topic and provided a framework for identifying factors that may lead to the intention to use new technology, which may determine the actual use of technology (i.e., technology acceptance). The higher levels of students’ perceived ease of use, and perceived usefulness of the e-texts, the more apt the student is to choose an e-text as opposed to a paper text. The lower costs of e-texts in comparison to paper texts would be a positive predictor of financial benefits for the students that choose to use e-texts. The financial gains in the purchasing of e-texts could lead to a positive impact on the total of college and education costs. The author also concluded that the market for recreational reading continues to grow for e-texts usage. Academic use of e-texts still represents a lesser portion of the market place. This study contributed to the body of knowledge, profession, and overall literature in the field of study regarding intentions to use new technology, user acceptance research, and information systems. The results of the study have provided a framework for launching new technology within a postsecondary school environment.

Effect of Individualized Curricular Accommodations, Incorporating Student Interest and the Impact on the Motivation and Occurrence/ Nonoccurrence of Disruptive Behavior Displayed By Students with Emotional/behavioral Disorders.

Teaff, Teresa L. 12 1900 (has links)
As a result of the reauthorization of the Individuals with Disabilities Education Act of 1997, schools must now consider positive behavioral interventions and strategies to address problem behavior of students with Emotional/Behavioral Disorders (E/BD). Given the poor behavioral, academic, and social outcomes for these students, there is a compelling need to identify effective, proactive interventions. Current literature has well established the ineffectiveness of traditional, punitive, and consequence-laden strategies to deal with behaviors. Research has shown the manipulation of antecedent stimuli, in the form of curricular adaptations, can provide a positive, proactive means of managing behavior. Specifically, curriculum modifications, based on student interest, are proposed as a positive, proactive strategy used to manipulate antecedent stimuli to improve the behavior of students with E/BD. The purpose of this study was to investigate the manipulation of antecedent stimuli through the implementation of individualized, curricular adaptations, based on student interest, to reduce the problem behavior of students exhibiting disruptive behaviors. A second purpose was to explore the effect of those adaptations on the behavior motivation of students with E/BD. In this study, curriculum modifications based on student interest were used to reduce disruptive behavior, increase desirable behavior, and effect change in the motivation for problem behavior among four elementary school boys with E/BD. Use of an ABAB reversal design, including interval data collection, and the use of a behavior rating scale and a motivation assessment scale were used to establish baseline data and determine effectiveness of the intervention. Results indicate that each student demonstrated a reduction in disruptive behavior, an increase in desirable behavior, and changes in motivation for behavior.

Recherche de gaz/mélange gazeux sans hexafluorure de soufre pour des applications haute tension

Nechmi, Houssem Eddine 12 December 2016 (has links)
Dans l’état actuel des techniques utilisées pour l’isolation gazeuse des systèmes d’énergie électrique à haute tension, l’hexafluorure de soufre (SF6) tient une place prépondérante en raison de ses performances diélectriques et chimiques (bonne tenue diélectrique, point d'ébullition bas, stabilité chimique, non toxicité, etc.) ; il est l’un des meilleurs isolants gazeux connus à ce jour. Il est principalement utilisé dans les appareils de coupure pour l’extinction de l’arc électrique, les lignes de transmission à isolation gazeuse et autres équipements de puissance. Cependant, de par sa taille excessive, sa durée de vie trop importante et son grand effet radiatif, la molécule de SF6 constitue un agent aggravant de l’effet de serre avec un potentiel de réchauffement global (PRG ou GWP en anglais) très élevé (23900 fois supérieur à celui du CO2). Ainsi, les recommandations internationales (COP3) et européennes (règlement (UE) n°517/2014) tendent à restreindre très fortement, voire interdire son utilisation pour préserver l’environnement. Depuis, une tâche importante a été engagée par les industriels pour trouver d’autres gaz ou mélanges de substitution avec moins d’impact sur l’environnement et des exigences diélectriques comparables ou supérieures à celles du SF6. Les candidats les plus prometteurs appartiennent tous au groupe des molécules poly-fluorées (CF3I, Perfluorinated Ketones, Octafluorotetra-hydrofuran, Hydrofluoroolefin (HFOs) ou heptafluoro-iso-butyronitrile(Fluoronitriles)), Ils offrent tous une tenue diélectrique entre 1.2 et 2.71 par rapport au SF6. Ces molécules candidates ouvrent des perspectives intéressantes pour la substitution de SF6 dans l’appareillage sous enveloppe métallique destiné pour le réseau T&D haute tension. Leur principal inconvénient réside dans leur masse moléculaire élevée, ce qui implique une température de fonctionnement plus élevée par rapport au SF6. Ce travail porte sur l’étude expérimentale des performances diélectriques des mélanges de Fluoronitriles-CO2. Les paramètres intrinsèques de l’avalanche électronique sont identifiés à partir des courants de la décharge stationnaire de Townsend. L’évaluation de ces courants a permis d’extraire le coefficient d’ionisation effectif pour différents mélanges de Fluoronitriles. Une comparaison du potentiel d’isolation de ces mélanges avec celui du SF6 pur, dans différentes géométries électrodes (sphère-plan, pointe-plan, sphère-sphère, système avec le profil de Bruce), sur une large gamme de pression et pour toutes les formes d'ondes de tension normalisées pour d'isolation est présentée. Les résultats de mesures de tensions de claquage de ces mélanges et du CO2 pur, pour comparaison, dans un système coaxial cylindrique de taille réelle, similaire à celui utilisé dans les postes à enveloppe métallique (GIS - Gas Insulated Switchgear), sont également présentés ; une étude de l’influence de la surface et de l’état de surface des électrodes sur la tenue diélectrique en fonction de différents paramètres (pression, rugosité, surface effective, forme de tension et polarité, température de gaz …) est faite. / SULPHUR hexafluoride, SF6, is the most common compressed gas used in high voltage power equipment since the 1950s and in HV transmissions and substations applications (GIS, GCB, GIL …), SF6 holds a prominent place because of its dielectric and chemical performance (high dielectric strength, non-toxicity, low condensation temperature, thermal stability, non-flammability, chemical inactivity with the other constituent materials of the apparatus, availability and moderate cost). It is one of the best insulators gas known today. Despite its excellent properties in both electrical insulation and current interruption performance, the excessive size, the radiative effect and atmospheric lifetime of SF6 molecule makes this gas an aggravating agent for the greenhouse gas effect, with a very high global warming potential (GWP) (23900 times higher than CO2). Thus, the international and European recommendations (COP 3) and (Regulation (EU) No 517/2014) respectively tend to strongly restrict or prohibit its use to preserve the environment. Since then, an important task was undertaken by manufacturers to find other gases or mixtures of substitution with less impact on the environment and dielectric performances comparable or superior to those of SF6. Naturally, the investigations were oriented towards halogenated products that have reduced GWP such as CF3I, Perfluorinated Ketones, Octafluorotetra-hydrofuran, Hydrofluoroolefin (HFOs) or heptafluoro-iso-butyronitrile (Fluoronitriles)), all offer a dielectric strength between 1.2 and 2.71 relative to SF6. These candidates open interesting perspectives for the substitution of SF6 in the GIS applications designed for high voltage T & D network. Their main disadvantage is their high molecular weight, which implies a higher operating temperature compared to SF6. This work deals with the experimental study of dielectric performance of Fluoronitriles CO2 mixtures. Intrinsic parameters of the measured steady state Townsend swarm currents are identified. The evaluation of the currents produce the effective ionization rate constant in different Fluoronitriles-CO2 mixtures. In addition, this work provides a conventional assessing of insulating performance with typical breakdown experiments, conducted for different field configurations over a wide pressure range and for all standard voltage waveforms. The experiments are conducted with different electrodes geometries namely plane-to-plane (Bruce profile), sphere-to-sphere, sphere-to-plane and rod-to-plane. AC and LI breakdown characteristics of CO2 and different Fluoronitriles /CO2 mixtures gas were experimentally analyzed in a real scale GIS coaxial test system. The main investigated parameters are the effect of roughness and effective surface area HV inner conductor on insulation performance, depending on various parameters (pressure, form and voltage polarity, gas temperature…).

核心技術能耐發展策略對筆記型電腦產業產品創新的影響-以華碩、宏碁開發小筆電產品為例 / The influence of core technology competence development strategy to notebook industry product innovation - A case study over Asus and Acer netbook product dvelopment

洪榮成, Hung, Richard Unknown Date (has links)
2007年6月,華碩電腦發表Eee PC精簡式筆記型電腦,此創新產品俟後由臺灣資訊工業策進會市場情報中心(MIC)統稱為精簡型小筆電,簡稱小筆電,英文名稱則採用美商英代爾對於這款產品的統稱:Netbook。 Eee PC所設定的目標市場著眼於消費性市場,將產品定位於已開發國家使用者的第二臺電腦以及開發中國家使用者的第一臺電腦。產品上市後掀起銷售高潮,由於小筆電的加入,筆記型電腦在2008年第三季出貨量首度超越桌上型電腦,比先前2007年預估提早兩年,Eee PC因而被譽為臺灣電腦廠商價值創新的一大步。 本研究主要的探討問題有四:核心技術能耐發展策略對於產品創新的影響為何? 品牌與ODM廠商在創新產品開發上的合作與分工為何? 品牌廠商因應競爭者之破壞性創新的作法為何? 核心技術能耐為基礎的產品創新在市場上所需具備的成功條件為何? 在研究設計上以策略與組織、技術、市場三構面做為主要分析架構。策略與組織構面由領導者企圖心、核心競爭優勢、企業文化、組織架構、企業網絡定位等變項構成;技術構面上由產品研發經驗、內部知識傳遞、外部資源網絡、產品開發管理等變項構成;市場構面由品牌效益、顧客需求、產品行銷、產業合作網絡等變項組成用以探討對於破壞性創新產品構思及開發階段的影響。研究方法上採用「個案研究法」,以領導廠商華碩與宏碁為研究對象。在資料上透過企業訪談與次級資料蒐集的方式來了解個案公司在創新產品的發展過程,並結合核心競爭力、產業價值鏈、破壞性創新、新產品開發程序、吸收能耐與知識傳遞、技術面競爭策略等學理加以分析,本研究所獲得的研究發現如下: 一.建立核心競爭能耐的方向及重點決定了企業在產業價值鏈的位置與所從事的價值活動。 二.企業基於核心技術能耐發展策略而對產品創新方向做出技術領導者與技術追隨者的不同策略選擇。技術領導者著重產品的破壞性創新設計,技術追隨者著重於產品成熟技術的市場性。 三.品牌廠商與ODM的研發製造合作關係上,考量中心點在於顧客對企業的認知價值。品牌廠商並以平均分配(Allocation)與相互制衡(Leverage)為策略,取得各家資源之長為己用。 四.設計代工廠從OEM經營模式進入ODM經營模式,在逐步接手研發價值活動後,ODM設計製造廠開始投入自主研發,成為個人電腦產品技術提供者。但在缺乏通路品牌下,所創造的產品創新價值只能透過品牌廠技術採用將創新價值傳達至消費者。 五.企業發展破壞性創新產品時,原價值網絡上具產業主導地位的供應商透過關鍵技術的掌握,並經由品牌行銷掌握終端使用者,形成不易突破的慣性,對於廠商產品創新產生鉗制作用。 六.企業發展破壞性創新產品若無法取得市場客戶對產品的價值認同,則雖有技術成就,但難以成為產品的競爭優勢。 七.企業在發展破壞性創新產品過程中,若缺乏行銷業務部門參與,將可能造成產品上市後的市場資訊掌握失準。 八.破壞性創新產品所設定於原價值網絡的目標市場,往往因為高科技產業的不確定性因素,在實際執行時意外產生新應用,產品因而進入新價值網絡的新市場。 九.破壞性創新產品進入新市場時不確定因素多,廠商因需求不易掌握而經常發生嘗試錯誤的探索行為,但市場晚入者觀察先驅者經驗,往往能立即掌握正確資訊而迅速反應市場需求。 十.企業發展破壞性創新產品,若未造成有效技術差距,技術領導者與市場先驅者將不易維持首動者優勢。技術追隨者與市場晚入者藉由學習領導者經驗將有機會快速超越。 本研究最後並提出一些實務上建議,以做為產業界發展核心技術能耐策略與發展破壞性創新產品的參考。 / In June, 2007, Asus Computer announced her Eee PC in Computex Taipei, Taiwan International Computer Exhibition.

Second, how brand owner works with ODM suppliers on innovative product development? Third, how brand owner reacts to disruptive innovation? Last, what are market successful factors of an innovative product which based on core technology competence? Analysis framework of this research consists of three aspects: strategy and organization, technology, marketing. As an exploratory study, research design is qualitative research and case study over certain firms: Asus and Acer, with 90% market shares of netbook in year 2008. For data gathering, primary data came from interviews to firms’ management team members, specifically R&D and PM Directors, secondary data studies came from varies sources: research reports, annual reports, and so on. To explore the influence of core technology competence toward product innovation in idea generation and product development stage, study of related theories in advance is necessary: core competence, value chain, disruptive innovation, new product development procedure, absorptive capability, knowledge transmission, and competitive strategy of technology. Discoveries of this research are: 1.Direction and focus of establishing core competence decides the firm’s position in value chain and the value activities firm engaged. 2.Core technology competence development strategy directs firm’s choice of technology leader or follower, leader focuses on innovative product design, follower focuses on mature technology’s market taking. 3.Customers perceive value is the key consideration that brand owners work with ODM suppliers. “Allocation and Leverage” are strategy that brand owners manage multiple ODM suppliers. 4.From OEM to ODM business model, ODM firms start to develop own independent research projects, this trend leads ODM to be technology supplier in foreseeable future. But, research results can only go through brand owners to consumer market. 5.Key technology suppliers of existing value network will obstruct disruptive innovation products through market’s inertia. 6.Technology based innovative products can’t have competitive advantage in the market without customer’s perceive value. 7.Sales marketing team’s participation is important for disruptive innovation during product development stage. 8.Unexpected new value network will emerge due to uncertainty of high-tech industry, new application out of target market leads to new value network which is different from existing one. 9.Pioneer frequently tries and error for disruptive innovation product due to uncertainty of market, late entrant learned from pioneer’s experience, and react to market demand efficiently. 10.Innovative product without technology gap, firm can’t maintain first mover advantage too long, technology follower have chance to transcend in short period. Conclusions of this research are summarized from above discoveries, and suggestions to industry firms made by this research can be reference to firms’ development strategy of core technology competence as well as product development of disruptive innovation.

台灣教育創新模式之探討:兩個表演藝術教育破壞性創新實例 / An education innovation model for Taiwan: two examples of disruptive innovation in performing arts education

紀博善, Dale Albanese Unknown Date (has links)
近年來,創造力教育受到越來越多守門人的關注,包括企業界領袖、學者專家、政策制定者和教育工作者。另外在學術界和教育界,也有 越來越多的人接受「創造力是可以教」的觀念。因此,追求文化和社會適當的教育創新模式來實施創造力教育是非常重要的。 接觸藝術、學習藝術是培養創造力的重要途徑, 但在正式教育體制很難提供機會平等的平台時,相關的教育守門人就必須創造機會解決此一問題。Christensen、Horn與Johnson (2008、2011)也認為傳統的教育創新只是進行永續性的創新,所以他們進而提出破壞性創新的教育模式,以彌補傳統創新教育模式之不足。 本研究的目的是在探討兩個台灣表演藝術教育破壞性創新的個案:紙風車319鄉村兒童藝術工程和台北景文高中之優人神鼓表演藝術班。本研究的研究方法包括文獻分析,深度訪談和觀察。研究結果發現紙風車319鄉村兒童藝術工程的破壞性教育模式提供更多的機會讓偏遠的兒童可以接觸藝術,對他們產生正面的影響。優人神鼓表演藝術班的教育創新模式讓具有藝術興趣和才能的學生開啟創新的學習管道,一方面發展他們的藝術才情,另一方面也可以在正式教育中表現良好。 / In recent years, creativity in education has received increased attention from gatekeepers - the business leaders, scholars, policy-makers, and educators – around the world. There is also growing acceptance in the academic and educational worlds that “creativity can be taught.” Thus it is now crucial to pursue culturally and socially appropriate models for implementing creativity education. Encountering and studying the arts is an important approach to developing creativity. However, when traditional formal education systems are unable to provide an equal platform for encountering the arts, relevant gatekeepers must come up with new solutions. Christensen, Johnson, & Horn (2008; 2011) write that traditionally, educational innovation has relied on sustaining innovation, which they hold is insufficient for new educational demands today. They propose instead a model of disruptive innovation for education, which has greater potential impact on the education system, to help close the gap between educational ideals and practice. Leadbeater and Wong (2010) further categorize innovations in either formal or informal educational settings. This study examines two cases of disruptive innovation in performing arts education from Taiwan: Paper Windmill Theatre’s First Mile, Kid’s Smile 319 Townships Art Project program and the U-Theatre Performing Arts Class at Taipei Jingwen High School. The research methods employed include document analysis, in-depth interviews, and observations. The research findings conclude that the 319 Project's disruptive innovation model for informal education provided children in remote locations with opportunities to encounter the arts, making a positive impact on their lives. The disruptive innovation model for formal education used by the U-Theatre Performing Arts Class gave students with interests and potential in performing arts a channel for their abilities, both helping them develop their artistic interests and talents and enter university.
