Download or read book Fondamenti di Informatica Temi d esame risolti written by D. Braga and published by Società Editrice Esculapio. This book was released on 2020-07-01 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Questo testo raccoglie, raggruppati per argomento, una serie di esercizi assegnati nei temi d’esame dei corsi di Informatica 1, Informatica A e Fondamenti di Informatica al Politecnico di Milano, per i corsi di laurea in Ingegneria Informatica, Ingegneria dell’Automazione e Ingegneria Matematica. Il testo si rivolge principalmente agli studenti dei corsi erogati per la Laurea di Primo Livello (nelle discipline dell’Ingegneria dell’Informazione). Più in generale, però, crediamo che questo testo costituisca un pratico e rapido riferimento per chi, studiando la materia, voglia vedere esempi compatti di codice che risolvono problemi relativamente semplici, ma rappresentativi delle tipiche difficoltà che si presentano nella gestione di tutte le strutture dati più classiche. Il testo include anche una breve sezione dedicata alle basi di dati relazionali e al linguaggio SQL, argomento trattato o accennato in molti corsi di informatica di base. Per quanto riguarda le soluzioni proposte, è importante sottolineare che il progetto di una soluzione, per quanto a problemi molto semplici come quelli trattati in questo volume, non produce comunque mai risultati univoci, poiché risente inevitabilmente degli stili e delle preferenze dei singoli. Gli autori dichiarano pertanto sin d’ora che soluzioni presentate sono influenzate dal loro stile. Non sono certo le uniche soluzioni corrette, dunque; anzi, in vari casi tra i commenti alle soluzioni proposte sono discusse alcune soluzioni alternative, e a volte sono riportati alcuni errori comuni. In particolare, poi, si è cercato di mostrare soluzioni ricorsive a tutti i problemi per i quali questo potesse essere fatto in modo compatto e conciso, per contribuire a convincere gli studenti che la ricorsione è un paradigma di computazione generale, e non semplicemente una modalità di scansione di alcune particolari strutture dati. Per semplicità di consultazione, in tutto il volume i testi degli esercizi, riportati così come comparivano nei temi d’esame assegnati, sono racchiusi all’interno di riquadri. Le nostre soluzioni, invece, sono liberamente impaginate tra tali riquadri. Ringraziamo Davide Barbieri, Francesco Bruschi, Alessandro Campi, Carlo Alberto Furia e Gerardo Pelosi per i consigli, le idee e i suggerimenti trasferitici nel tempo in cui questo materiale è andato accumulandosi. Il testo riserva una particolare attenzione a temi “delicati” quali la ricorsione, i record di attivazione e la memoria dinamica. Include anche una breve sezione dedicata alle basi di dati relazionali e al linguaggio SQL, argomento trattato o accennato in molti corsi di informatica di base.

This book was released on 2020-09-01 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nell'ambito della formazione universitaria, è andato sempre più allargandosi il numero di corsi di base che adottano il C come linguaggio di programmazione. La scelta risulta sicuramente giustificata dall'ampio uso che dello stesso si fa in ambito industriale e accademico e dalla propedeuticità dello stesso in vista di un successivo passaggio alla programmazione in C++, ma lo studente che affronta per la prima volta l'attività di programmazione incontra spesso parecchie difficoltà nella risoluzione di problemi applicativi. Risultano particolarmente critiche: la formulazione dell'algoritmo risolutivo, la scelta delle strutture dati e l'uso appropriato delle - comode ma non immediate - funzioni di libreria per la gestione dell'input/output. Il presente volume raccoglie alcuni esercizi e temi d'esame (relativi al corso di Fondamenti di Informatica tenuto dal Prof. Licia Sbattella presso il Politecnico di Milano) ritenuti significativi nell'ambito: della definizione dell'algoritmo risolutivo, della scelta e gestione di tipi di dati e delle strutture di controllo, dell'uso dei file, della definizione e utilizzo di strutture dinamiche, della definizione e utilizzo di algoritmi di tipo ricorsivo. Ogni soluzione propone: una dettagliata spiegazione delle scelte operate (in termini di algoritmo, di strutture dati, di funzioni di libreria), lo pseudocodice relativo all'algoritmo implementato, il codice relativo all'implementazione, i risultati attesi a fronte di un determinato insieme di dati d'ingresso.

Available in PDF, EPUB and Kindle. Book excerpt: The demand for academic coursework and corporate training programs using the Internet and computer-mediated communication networks increases daily. The development and implementation of these new programs requires that traditional teaching techniques and course work be significantly reworked. This handbook consists of 20 chapters authored by experts in the field of teaching in the online environment to adult students enrolled in graduate university degree programs, corporate training programs, and continuing education courses. The book is organized to first lay a conceptual and theoretical foundation for implementing any online learning program. Topics such as psychological and group dynamics, ethical issues, and curriculum design are covered in this section. Following the establishment of this essential framework are separate sections devoted to the practical issues specific to developing a program in either an academic or corporate environment. Whether building an online learning program from the ground up or making adjustments to improve the effectiveness of an existing program, this book is an invaluable resource.--From Amazon.
Download or read book The Myth of Achievement Tests written by James J. Heckman and published by University of Chicago Press. This book was released on 2014-01-14 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: Achievement tests play an important role in modern societies. They are used to evaluate schools, to assign students to tracks within schools, and to identify weaknesses in student knowledge. The GED is an achievement test used to grant the status of high school graduate to anyone who passes it. GED recipients currently account for 12 percent of all high school credentials issued each year in the United States. But do achievement tests predict success in life? The Myth of Achievement Tests shows that achievement tests like the GED fail to measure important life skills. James J. Heckman, John Eric Humphries, Tim Kautz, and a group of scholars offer an in-depth exploration of how the GED came to be used throughout the United States and why our reliance on it is dangerous. Drawing on decades of research, the authors show that, while GED recipients score as well on achievement tests as high school graduates who do not enroll in college, high school graduates vastly outperform GED recipients in terms of their earnings, employment opportunities, educational attainment, and health. The authors show that the differences in success between GED recipients and high school graduates are driven by character skills. Achievement tests like the GED do not adequately capture character skills like conscientiousness, perseverance, sociability, and curiosity. These skills are important in predicting a variety of life outcomes. They can be measured, and they can be taught. Using the GED as a case study, the authors explore what achievement tests miss and show the dangers of an educational system based on them. They call for a return to an emphasis on character in our schools, our systems of accountability, and our national dialogue.

Download or read book Plant Genetic Conservation written by Nigel Maxted and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent development of ideas on biodiversity conservation was already being considered almost three-quarters of a century ago for crop plants and the wild species related to them, by the Russian geneticist N.!. Vavilov. He was undoubtedly the first scientist to understand the impor tance for humankind of conserving for utilization the genetic diversity of our ancient crop plants and their wild relatives from their centres of diversity. His collections showed various traits of adaptation to environ mental extremes and biotypes of crop diseases and pests which were unknown to most plant breeders in the first quarter of the twentieth cen tury. Later, in the 1940s-1960s scientists began to realize that the pool of genetic diversity known to Vavilov and his colleagues was beginning to disappear. Through the replacement of the old, primitive and highly diverse land races by uniform modem varieties created by plant breed ers, the crop gene pool was being eroded. The genetic diversity of wild species was equally being threatened by human activities: over-exploita tion, habitat destruction or fragmentation, competition resulting from the introduction of alien species or varieties, changes and intensification of land use, environmental pollution and possible climate change.

Download or read book The Mathematics Teacher in the Digital Era written by Alison Clark-Wilson and published by Springer Science & Business Media. This book was released on 2013-12-08 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume addresses the key issue of the initial education and lifelong professional learning of teachers of mathematics to enable them to realize the affordances of educational technology for mathematics. With invited contributions from leading scholars in the field, this volume contains a blend of research articles and descriptive texts. In the opening chapter John Mason invites the reader to engage in a number of mathematics tasks that highlight important features of technology-mediated mathematical activity. This is followed by three main sections: An overview of current practices in teachers’ use of digital technologies in the classroom and explorations of the possibilities for developing more effective practices drawing on a range of research perspectives (including grounded theory, enactivism and Valsiner’s zone theory). A set of chapters that share many common constructs (such as instrumental orchestration, instrumental distance and double instrumental genesis) and research settings that have emerged from the French research community, but have also been taken up by other colleagues. Meta-level considerations of research in the domain by contrasting different approaches and proposing connecting or uniting elements

Download or read book The Art Science of Learning Design written by Marcelo Maina and published by Springer. This book was released on 2015-07-21 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live in an era defined by a wealth of open and readily available information, and the accelerated evolution of social, mobile and creative technologies. The provision of knowledge, once a primary role of educators, is now devolved to an immense web of free and readily accessible sources. Consequently, educators need to redefine their role not just “from sage on the stage to guide on the side” but, as more and more voices insist, as “designers for learning”. The call for such a repositioning of educators is heard from leaders in the field of technology-enhanced learning (TEL) and resonates well with the growing culture of design-based research in Education. However, it is still struggling to find a foothold in educational practice. We contend that the root causes of this discrepancy are the lack of articulation of design practices and methods, along with a shortage of tools and representations to support such practices, a lack of a culture of teacher-as-designer among practitioners, and insufficient theoretical development. The Art and Science of Learning Design (ASLD) explores the frameworks, methods, and tools available for teachers, technologists and researchers interested in designing for learning Learning Design theories arising from findings of research are explored, drawing upon research and practitioner experiences. It then surveys current trends in the practices, methods, and methodologies of Learning Design. Highlighting the translation of theory into practice, this book showcases some of the latest tools that support the learning design process itself.
Download or read book Identifying Citizens written by David Lyon and published by John Wiley & Sons. This book was released on 2013-05-03 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: New ID card systems are proliferating around the world. These may use digitized fingerprints or photos, may be contactless, using a scanner, and above all, may rely on computerized registries of personal information. In this timely new contribution, David Lyon argues that such IDs represent a fresh phase in the long-term attempts of modern states to find stable ways of identifying citizens. New ID systems are “new” because they are high-tech. But their newness is also seen crucially in the ways that they contribute to new means of governance. The rise of e-Government and global mobility along with the aftermath of 9/11 and fears of identity theft are propelling the trend towards new ID systems. This is further lubricated by high technology companies seeking lucrative procurements, giving stakes in identification practices to agencies additional to nation-states, particularly technical and commercial ones. While the claims made for new IDs focus on security, efficiency and convenience, each proposal is also controversial. Fears of privacy-loss, limits to liberty, government control, and even of totalitarian tendencies are expressed by critics. This book takes an historical, comparative and sociological look at citizen-identification, and new ID cards in particular. It concludes that their widespread use is both likely and, without some strong safeguards, troublesome, though not necessarily for the reasons most popularly proposed. Arguing that new IDs demand new approaches to identification practices given their potential for undermining trust and contributing to social exclusion, David Lyon provides the clearest overview of this topical area to date.

Download or read book Exploring Big Historical Data The Historian s Macroscope Second Edition written by Shawn Graham and published by World Scientific. This book was released on 2022-02-24 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every day, more and more kinds of historical data become available, opening exciting new avenues of inquiry but also new challenges. This updated and expanded book describes and demonstrates the ways these data can be explored to construct cultural heritage knowledge, for research and in teaching and learning. It helps humanities scholars to grasp Big Data in order to do their work, whether that means understanding the underlying algorithms at work in search engines or designing and using their own tools to process large amounts of information.Demonstrating what digital tools have to offer and also what 'digital' does to how we understand the past, the authors introduce the many different tools and developing approaches in Big Data for historical and humanistic scholarship, show how to use them, what to be wary of, and discuss the kinds of questions and new perspectives this new macroscopic perspective opens up. Originally authored 'live' online with ongoing feedback from the wider digital history community, Exploring Big Historical Data breaks new ground and sets the direction for the conversation into the future.Exploring Big Historical Data should be the go-to resource for undergraduate and graduate students confronted by a vast corpus of data, and researchers encountering these methods for the first time. It will also offer a helping hand to the interested individual seeking to make sense of genealogical data or digitized newspapers, and even the local historical society who are trying to see the value in digitizing their holdings.
