Zum Einfluss von Computeralgebrasystemen auf mathematische Grundfertigkeiten: Eine empirische Bestandsaufnahme (Essener Beiträge zur Mathematikdidaktik)

by Robert Neumann

Mit einer empirischen Studie untersucht Robert Neumann, ob sich Leistungsunterschiede von Studienanfängern im Bereich mathematischer Grundfertigkeiten auf den in der Schule verwendeten Taschenrechnertyp zurückführen lassen. Auf der Basis von Leistungstests mit über 450 Studierenden liefert der Autor einen empirisch gestützten Beitrag zu den Langzeitauswirkungen verschiedener Computeralgebrasysteme, die im Mathematikunterricht verwendet wurden. Dabei kann der Autor im Bereich der Interpretation von Funktionsgraphen signifikante Unterschiede feststellen. Seine Ergebnisse weisen darauf hin, dass es eine Gruppe von Schülern und Schülerinnen gibt, die bisher nicht im erhofften Maße von Rechnertechnologien profitieren. ​

Zum Einfluss digitaler Werkzeuge auf die Konstruktion mathematischen Wissens (Studien zur theoretischen und empirischen Forschung in der Mathematikdidaktik)

by Michael Rieß

Michael Rieß untersucht die qualitativen Unterschiede in der Konstruktion mathematischen Wissens nach einem Unterricht mit digitalen Werkzeugen. Dazu erarbeitet er zunächst auf der Basis allgemeiner Lerntheorien ein Wirkungsmodell für den Einfluss der im Mathematikunterricht verwendeten Werkzeuge auf individuelle mathematische Konzepte. Das Modell bildet die Grundlage für das Design der empirischen Studie, deren Ergebnisse im Kontext der entwickelten Theorie Einblicke in die mögliche Beantwortung der Fragestellung liefern. Der Autor identifiziert unterschiedliche Denkweisen, Lösungsstrategien und Verwendungen mathematischer Darstellungen und zeigt, dass insbesondere die beobachteten Differenzen Charakteristika aufweisen, die über die Verwendung unterschiedlicher Handlungsschemata hinausgehen. Dies stützt die Annahme, dass der Umgang mit verschiedenen Werkzeugen zu fundamentalen Änderungen individueller mathematischer Konzepte führen kann.

ZK Developer's Guide: Developing Responsive User Interfaces For Web Applications Using Ajax, Xul, And The Open-source Zk Rich Web Client Development Framework

by Jurgen Schumacher Markus Stauble

ZK is an open-source web development framework that enables web applications to have the rich user experiences and low development costs that desktop applications have had for years. ZK includes an Ajax-based event-driven engine, rich sets of XML User Interface Language (XUL) and XHTML components, and a markup language. The ZK rich client framework takes the so-called server-centric approach: the content synchronization of components and the event pipelining between clients and servers are automatically done by the engine and Ajax plumbing codes are completely transparent to web application developers. Therefore, the end users get rich user interfaces with similar engaged interactivity and responsiveness to that of desktop applications, while for programmers, development remains similar in simplicity to that of desktop applications. This book is a Developer's Guide that steps you through the ZK framework with examples. It starts with installing and configuring ZK and takes you on to integrate it with other frameworks. By the time you are through the book you will be able to build an application on your own.

Zeroing Dynamics, Gradient Dynamics, and Newton Iterations

by Lin Xiao Yunong Zhang Zhengli Xiao Mingzhi Mao

Neural networks and neural dynamics are powerful approaches for the online solution of mathematical problems arising in many areas of science, engineering, and business. Compared with conventional gradient neural networks that only deal with static problems of constant coefficient matrices and vectors, the authors’ new method called zeroing dynamics solves time-varying problems. Zeroing Dynamics, Gradient Dynamics, and Newton Iterations is the first book that shows how to accurately and efficiently solve time-varying problems in real-time or online using continuous- or discrete-time zeroing dynamics. The book brings together research in the developing fields of neural networks, neural dynamics, computer mathematics, numerical algorithms, time-varying computation and optimization, simulation and modeling, analog and digital hardware, and fractals. The authors provide a comprehensive treatment of the theory of both static and dynamic neural networks. Readers will discover how novel theoretical results have been successfully applied to many practical problems. The authors develop, analyze, model, simulate, and compare zeroing dynamics models for the online solution of numerous time-varying problems, such as root finding, nonlinear equation solving, matrix inversion, matrix square root finding, quadratic optimization, and inequality solving.

Zero Comments: Blogging and Critical Internet Culture (Kultur- Und Medientheorie Ser.)

by Geert Lovink

In Zero Comments, internationally renowned media theorist and 'net critic' Geert Lovink revitalizes worn out concepts about the Internet and interrogates the latest hype surrounding blogs and social network sites. In this third volume of his studies into critical Internet culture, following the influential Dark Fiber and My First Recession, Lovink develops a 'general theory of blogging.' He unpacks the ways that blogs exhibit a 'nihilist impulse' to empty out established meaning structures. Blogs, Lovink argues, are bringing about the decay of traditional broadcast media, and they are driven by an in-crowd dynamic in which social ranking is a primary concern. The lowest rung of the new Internet hierarchy are those blogs and sites that receive no user feedback or 'zero comments'. Zero Comments also explores other important changes to Internet culture, as well, including the silent globalization of the Net in which the West is no longer the main influence behind new media culture, as countries like India, China and Brazil expand their influence and looks forward to speculate on the Net impact of organized networks, free cooperation and distributed aesthetics.

Zend Framework 2 Application Development

by Christopher Valles

The book is really pragmatic, focusing on the key aspects you usually need to create an application. We skip the boring theory and jump straight to the action. Also, the examples don't try to be perfect, they just show the topic in question or the tool/components we are using. Here the focus is on the framework itself not on how to architect applications. The book will spend a lot of time reviewing the examples and each chapter is created around the example used to explain the topics so the example is first, then the explanation.This book is great for you if you are new to Zend Framework 2 and are looking to get a practical approach in how to use the framework. This book will be also really helpful if you are a Zend Framework 1 user but you want to adapt you knowledge to the new version of the framework. It's assumed that you will have good experience using PHP and specially with the Object Oriented programming paradigm.
