Putting theory into practice: The creation of REALs in the context of today's universities
Rich Environments for Active Learning (REALs), as described by R. Scott Grabinger and Joanna Dunlap, are comprehensive educational systems based on constructivist principles that present an intellectual and practical challenge to university lecturers. As teachers and researchers, academics are concerned with improving the learning potential of teaching strategies and, to this end, the theory of the REAL provides inspiration and ideas based on sound theoretical principles. Yet in the context of the current pressured climate, having the time and resources to put such an extensive, theory into practice can seem little more than a pipeâdream. It is argued that using a computerâbased application such as the Hypermedia Learning Tutorials (HLTs) as the heart of a REAL allows lecturers to take positive steps towards the creation of comprehensive, flexible, integrated learning environments. The concept of the HLT is discussed and a practical application in the field of advanced secondâlanguage acquisition is described. Based on conceptual analysis and the results of preliminary student evaluation, it is argued that the HLT encompasses both in theory and in practice the chief qualities of REALs and can form the basis for their creation in a wide variety of disciplines
Some issues in the 'archaeology' of software evolution
During a software project's lifetime, the software goes through many changes, as components are added, removed and modified to fix bugs and add new features. This paper is intended as a lightweight introduction to some of the issues arising from an `archaeological' investigation of software evolution. We use our own work to look at some of the challenges faced, techniques used, findings obtained, and lessons learnt when measuring and visualising the historical changes that happen during the evolution of software
Harnessing Technology: new modes of technology-enhanced learning: opportunities and challenges
A report commissioned by Becta to explore the potential impact on education, staff and learners of new modes of technology enhanced learning, envisaged as becoming available in subsequent years. A generative framework, developed by the researchers is described, which was used as an analytical tool to relate the possibilities of the technology described to learning and teaching activities.
This report is part of the curriculum and pedagogy strand of Becta's programme of managed research in support of the development of Harnessing Technology: Next Generation Learning 2008-14. A system-wide strategy for technology in education and skills.
Between April 2008 and March 2009, the project carried out research, in three iterative phases, into the future of learning with technology. The research has drawn from, and aims to inform, all UK education sectors

Kymatio: Scattering Transforms in Python
The wavelet scattering transform is an invariant signal representation
suitable for many signal processing and machine learning applications. We
present the Kymatio software package, an easy-to-use, high-performance Python
implementation of the scattering transform in 1D, 2D, and 3D that is compatible
with modern deep learning frameworks. All transforms may be executed on a GPU
(in addition to CPU), offering a considerable speed up over CPU
implementations. The package also has a small memory footprint, resulting
inefficient memory usage. The source code, documentation, and examples are
available undera BSD license at https://www.kymat.io

Measuring constructive alignment: an alignment metric to guide good practice
We present a computational model that represents and computes the level to which an educational design is constructively aligned. The model is able to provide âalignment metricsâ for both holistic and individual aspects of a programme or module design. A systemic and structural perspective of teaching and learning underpins the design of the computational model whereby Bloomâs taxonomy is used as a basis for categorising the core components of a teaching system and some basic principles of generative linguistics are borrowed for representing alignment structures and relationships. The degree of alignment is computed using Set theory and linear algebra. The model presented forms the main processing framework of a software tool currently being developed to facilitate teachers to systematically and consistently produce constructively aligned programmes of teaching and learning. It is envisaged that the model will have broad appeal as it allows the quality of educational designs to be measured and works on the principle of âpractice techniquesâ and âlearning elicitedâ as opposed to content
Cyclical Flow: Spatial Synthesis Sound Toy as Multichannel Composition Tool
This paper outlines and discusses an interactive system designed as a playful âsound toyâ for spatial composition. Proposed models of composition and design in this context are discussed. The design, functionality and application of the software system is then outlined and summarised. The paper concludes with observations from use, and discussion of future developments
Evaluation of Computational Grammar Formalisms for Indian Languages
Natural Language Parsing has been the most prominent research area since the genesis of Natural Language Processing. Probabilistic Parsers are being developed to make the process of parser development much easier, accurate and fast. In Indian context, identification of which Computational Grammar Formalism is to be used is still a question which needs to be answered. In this paper we focus on this problem and try to analyze different formalisms for Indian languages
