Van Hiele Model

In secondary mathematics, students often see little connection between geometry and the real-life mathematical situations around them. When asked to describe geometric figures, their descriptions are sometimes no more than an identification of sides and angles. They have not had experience in using more than one property in a mathematical situation or in describing how two geometric properties are related. The van Hiele model of how students learn geometry proposes that students' understandings of geometry move from recognition to description to analysis (Fuys, Geddes, and Tischler 1988). For students to make this transition to analytic thinking, teachers need to create problem situations that enhance development of students' intuitive understandings. These investigations allow students to explore relationships among geometric shapes and to make conjectures about properties. The conjectures can then be stated formally as theorems.

The study explored the pre-service secondary Mathematics teachers’ levels of geometric thinking in geometry and their enacted example space function while they were exposed to van Hiele model instruction. The findings of the study reveal that most of the students were functioning at the recognition level in plane geometry and the highest geometric thinking level manifested prior to their exposure to van Hiele model is the informal deduction level. The evidences based on the study show that students’ example space function from various phases of instruction does not depend on their levels of geometric thinking that they had in plane geometry. Students with various levels of geometric thinking were able to generate quality examples across phases of instruction. Evidences likewise support the claim that van Hiele model assists students’ development of their example space function. Prior to the instruction misconception on properties of prism was evident among students. After the instruction, the breadth and the depth of understanding in relation to properties of prism was evident based on the quality of examples they provided. The most dominant geometric thinking level after students’ exposure to the van Hiele model instruction is also the recognition level.

This book deals with practical or real life aspects of public finance. It focuses on the growth in the activities of governments, in a world that expects more than in the past from governments. The book focuses on the growing complexity in both the work of the private market and that of the public sector. It stresses that part of the growing complexity is due to the more ambitious role that governments tried to play today, while part is due to choices made by governments, so that complexity may be partly avoidable. This was important in the different pursuit of social welfare by different countries. Complexity has increased opportunities for abuses, for rent seeking, and for mistakes in policies. It may also have increased the attraction of populist policies that claim to offer magical or easy solutions to problems. A major conclusion of the book is that the objective of simplicity in laws and in policies should be given more importance by both economists and governments.

AbstractEffective treatment of frequent oil spills and endless discharged oily wastewater is crucial for the ecosystem and human health. In the past two decades, the collection of oil from water surface has been widely studied through the simple fabrication of superhydrophobic meshes with various coating materials, but little attention is paid to the design aspects of the meshes based oil-collecting device and practical oil collection. Here, 3D-printing devices with different configurations of (super)hydrophobic meshes, circular truncated cone (CTC), cylinder and inverted CTC, and the same inverted cone-shaped structure (below the meshes for temporary oil storage) are investigated. Results demonstrate that the CTC meshes based device especially for an oblate one not only shows higher stability and discharge of the collected oils than previous reports, but also allows floating oils to enter the (super)hydrophobic mesh faster. We anticipate that future success in developing high-performance (super)hydrophobic meshes and the further optimization of the CTC mesh-based device parameters will make our proposed device more practical for the treatment of real-life oil spills.

Based on research, milennials have one prominent character over the past generations, it is creative thinking. after several studies milenials have a huge interest on fashion and craft, as seen on their creative activity both In real life and digital life related to it. Indonesian Creative Entrepreneurs nowadays are dominated with Millennials1. But what prevent their bussinesses from growing are the synergy inbetween that is too complicated, waisting their time and money. Creative Hub is a space, sustainably supporting creative entrepreneurs and people to gather, collaborate, and grow. Createur itself is a combination of Creative and Entrepreneur. Createur located near Pasar Baru, a historic shopping center that supply various things related to fashion and craft, there are also skilled workers related. Design method that was used is Pattern Language by studying physical pattern around site and recreating new pattern associated with the building programs produced. Createur in this case provide various kinds of facilty related from idea searching, designing, producing, to publishing. Milenials that was working inside the Creative Hub can easily jump to the field discovering materials. watching the skilled workers, and practice directly inside the Creative Hub. AbstrakBerdasarkan pengkajian, milenials memiliki satu karakteristik yang menonjol dari generasi sebelumnya, yakni berpikir kreatif. Setelah melakukan beberapa studi milenials memiliki minat yang besar terhadap bidang Fashion dan Kriya, hal ini terlihat dari banyaknya aktivitas kreatif milenials baik di dunia nyata maupun di dunia maya yang terkait dengan kedua hal tersebut. Pelaku usaha kreatif di indonesia saat ini didominasi oleh Milenials. Namun yang menjadi penghalang berkembangnya usaha kreatif milenials adalah sinergi usaha yang terlalu rumit dan membuang banyak waktu dan biaya. Pusat Kreativitas adalah ruang yang secara berkelanjutan mendukung pelaku usaha kreatif dan orang-orang untuk berkumpul, berkolaborasi, dan berkembang. Createur sendiri adalah gabungan dari creative dan entrepreneur yang artinya adalah pelaku usaha kreatif. Createur berlokasi di dekat Pasar Baru, pusat perbelanjaan bersejarah yang menyediakan berbagai macam kebutuhan yang berhubungan dengan fashion dan kriya didalamnya-pun banyak tenaga terampil terkait. Metode perancangan yang digunakan adalah pattern language dengan mengkaji pola fisik di sekitar tapak dan membuat pola baru dengan mengaitkan dengan program bangunan yang dihasilkan. Createur dalam hal ini menyediakan berbagai macam fasilitas yang berhubungan mulai dari pencarian ide, mendesain, produksi, hingga publikasi. Milenials yang sedang bekerja di dalam Pusat Kreativitas dapat dengan mudah terjun ke lapangan berbelanja bahan produksi, melihat para tenaga ahli bekerja, dan langsung mempraktikannya di dalam Pusat Kreativitas.

Abstract The practical orientation of action research, together with its embedded and participative principles, means it is particularly suited to complex, interconnected questions and ‘real life’ systemic issues. In the realm of first-person action research, Judi Marshall’s (1999) influential article “Living Life as Inquiry” described how such research can extend to one’s whole life whereby professional and personal questions can be set within politically relevant frames. Over the past two decades, many students and researchers have worked with and drawn much imaginative inspiration from the idea of living life as inquiry (LLI). However little has been written to describe how the practice develops and the many forms it can take. This article draws on our extensive experience as inquirers ourselves and as educators, working with students and change agents motivated to address social and environmental concerns. Twenty years after the original article we have conducted a reflective review that included surveying the literature, and working in depth with a range of stories and current practices. From this comes a textured expansion of the language and practice of living life as inquiry as it is approached from the specificity of people’s lives. Through narrative and visual textures, we present views into the many different ways LLI is developed through day-to-day practices of experimentation, data gathering, artistic exploration, intervention and reflection. We explore what this means for quality in the enactment of inquiry. The article draws particular attention to the embodied nature of inquiry and seeks to capture its fleeting, processual quality.

The Great War

AbstractPat Hanna's Famous Diggers, a professional vaudeville theatre troupe comprising ex-Great War Anzac soldiers (initially, mainly New Zealanders, as Hanna was himself) played for nearly two years (1923–24) at the old Cremorne Theatre in Brisbane. One item Hanna premiered at the Cremorne was Louis XI, a short (ten-minute) comic sketch he wrote himself. Modernism in the inter-war years, given its usual location within avant-garde aesthetics, high culture, internationalism and radical politics, is not — with the notable exception of Brecht's cabaret work in the 1920s — usually associated with popular theatre. While one comic playlet hardly challenges that positioning, Louis XI was a direct result of the Great War's profound reshaping of modern life. Many of the dramatised sketches performed by Hanna's company, including Louis XI, were structured around a contrast between events as they had occurred in the trenches and as they were portrayed in a utopian or dystopian fantasy, sometimes triggered by shell shock or a dream. Several, again including Louis XI, involve the past, and express the curiosity and cultural dislocation Australian- and New Zealand-born soldiers felt as they moved for the first time through real-life landscapes and architecture they had known only from popular history and romance.

The activity of fieldwork, that is research conducted with individuals and groups in a real-life and by implication, real-time setting or living environment rather than research under controlled conditions and specific time-frames, continues to draw strong attention and criticisms. Given the plethora of these schools of thought and their critiques over the past decades including relativism in its intense expressions, emphases on quantification as a sine-qua-non, hermeneutics, praxis, semiotics, deconstructionism and essentially “post-modernist” approaches to enduring questions of objectivity, recording behaviour, methodological rigor, meaning and their epistemological references, it is significant that (1) fieldwork still continues and does so in a variety of disciplines, and (2) most criticisms have been directed essentially at issues of validity, viability and reliability in relation to “data”, rather than some grand meta-disciplinary demise.There are those who would dearly like to throw baby, bathwater and the entire endeavour out, and such critiques are important: in their confabulations, they evoke enduring and profound issues with trenchancy. Nor have political assaults been slow to enter the battle: fieldwork, especially as perceived via an increasingly hapless anthropology, is seen as an enduring colonial tool, an exploiter of the ethnic domain, a servant of capitalism and product of the western will to power.
