Lifelong learning and second-order learning objects

Current cultural, social, and economic trends challenge traditional concepts of learning and lifelong learning. This paper draws on the twofold nature of learning in a knowledge society and explores options for technological support. The concept of Second‐Order Learning Objects is introduced as a potential means to foster generative learning. Generative learning goes beyond that what is already known and extends or transforms the socially shared knowledge including its artefacts and practices. According to the notion of individual and social learning as a process of reflective action, the role of strategies and media for reflection and inquiry is stressed. This paper outlines the use of schematically represented strategies for learning and reflection and sketches important features of a pursuant modelling approach.     

The trouble with learning objects

Object-oriented instructional design (OOID) offers the promise of universal access to online instructional materials, increased productivity among trainers and educators, and solutions for individualizing learning. However, it is unclear whether it can fulfill these promises to the degree many envision. As with every new instructional technology, it is easy to become overoptimistic about learning objects, but problems of education are always more complex than technology alone can solve. In this article, I take a critical look at the proposed benefits of learning objects described in the published literature, particularly scalability andadaptability. I also look at both the difficulties in defining the term learningobject and the limitations of metaphors used to describe the concept, and concludes with propositions for learning object usage. The title of this article is a reference to the popular Star Trek episode, “The Trouble with Tribbles” (Gerrold, 1967). In that episode, one of the crew of theEnterprise adopts a cute, furry, and apparently harmless alien creature for a pet, only to find that it reproduces with a fury. Soon the population of tribbles outstrips the resources of the ship, floods its compartments, and threatens the crew's mission, as well as their lives. This was chosen to suggest that while object-oriented instructional design holds tremendous promise on many levels, it also has potential dangers. Instructional designers need to carefully study these creatures called, learning objects before adopting them so readily, lest they find themselves up to their ears in ineffective education and training endeavors. and a doctoral student in Educational Leadership and Innovation at the University of Colorado at Denver.     

Infants' learning about words and sounds in relation to objects

In acquiring language, babies learn not only that people can communicate about objects and events, but also that they typically use a particular kind of act as the communicative signal. The current studies asked whether 1-year-olds' learning of names during joint attention is guided by the expectation that names will be in the form of spoken words. In the first study, 13-month-olds were introduced to either a novel word or a novel sound-producing action (using a small noisemaker). Both the word and the sound were produced by a researcher as she showed the baby a new toy during a joint attention episode. The baby's memory for the link between the word or sound and the object was tested in a multiple choice procedure. Thirteen-month-olds learned both the word-object and sound-object correspondences, as evidenced by their choosing the target reliably in response to hearing the word or sound on test trials, but not on control trials when no word or sound was present. In the second study, 13-month-olds, but not 20-month-olds, learned a new sound-object correspondence. These results indicate that infants initially accept a broad range of signals in communicative contexts and narrow the range with development.     

Promises and pitfalls of learning objects

Learning objects (LOs), generally understood as digital learning resources shared through the Internet and reused in multiple learning contexts, have aroused worldwide enthusiasm in the field of educational technology during the last years. Although LOs and LO systems offer tremendous possibilities to improve educational practices, there are many theoretical problems and practical shortcomings which are usually neglected. In this article we introduce the promises of cost‐effectiveness, reusability, modifiability and adaptability associated with LOs. Then we critically look at the problems underlying the LO approach, and provide our own alternative interpretation of LOs as useful elements of meaningful learning environments. Because of their flexible nature, LOs and LO systems can be used to support a variety of learning theories and instructional strategies—both sophisticated and reductionist ones (Parrish, 2004 Parrish, P. E. 2004. The trouble with learning objects. Educational Technology, Research & Development, 52(1): 49–67. [Crossref], [Web of Science ®] [Google Scholar]). LOs per se are not necessarily pedagogically functional or non‐functional, but their pedagogical value is determined through their context of use. The implementation of LOs requires a sound pedagogical grounding, and we argue that only by using LOs according to the principles of contemporary learning theories can their promises be fulfilled.     

Towards a useful classification of learning objects

The learning object remains an ill-defined concept, despite numerous and extensive discussion in the literature. This paper attempts to address this problem by providing a classification that potentially brings together various perspectives of what a learning object may be. Six unique types of learning objects are proposed and discussed: presentation, practice, simulation, conceptual models, information and contextual representation objects. The common characteristics of each are synthesized in a proposal that a learning object is best described as a representation designed to afford uses in different educational contexts. The classification of learning objects proposed could be useful as a framework for designers of digital resources and for those engaged in use of these resources in educational contexts.

Novel noun and verb learning in Chinese-, English-, and Japanese-speaking children

When can children speaking Japanese, English, or Chinese map and extend novel nouns and verbs? Across 6 studies, 3‐ and 5‐year‐old children in all 3 languages map and extend novel nouns more readily than novel verbs. This finding prevails even in languages like Chinese and Japanese that are assumed to be verb‐friendly languages (e.g., T. Tardif, 1996 ). The results also suggest that the input language uniquely shapes verb learning such that English‐speaking children require grammatical support to learn verbs, whereas Chinese children require pragmatic as well as grammatical support. This research bears on how universally shared cognitive factors and language‐specific linguistic factors interact in lexical development.     

Effectiveness of learning objects in various instructional settings

Learning objects (LOs), generally understood as digital learning resources shared and accessed through the Internet and reused in multiple learning contexts, have aroused enthusiasm in the field of educational technology. Although LOs offer many possibilities to change educational practices, there is a lack of empirical evidence on the effectiveness and usefulness of LOs. This paper reports results from three studies on effectiveness of LOs in various instructional settings. According to the results, there exists interaction between the effectiveness of LOs and various instructional arrangements. In order to be effective LOs require carefully designed learning environments and instructional arrangements. LOs themselves do not guarantee high‐quality learning performance and meaningful learning activities. It is the context of use together with instructional arrangements that defines the pedagogical value of LOs.     

An evaluation of European learning objects in use

Most studies on reusable digital learning materials, learning objects (LOs), relate to their use in universities. Few empirical studies exist to explore the impact of LOs on pedagogy, especially in schools. This paper provides evidence from an evaluation of the use of LOs in schools. The evidence is from a European Union‐funded project, Context eLearning with Broadband Technologies (CELEBRATE), involving 500 schools in six countries across Europe, in a pilot to examine the impact of LOs on pedagogy. It brought together producers and users to try out technically and pedagogically sound ways of producing, making available through a portal, and using LOs. This paper reports data from both quantitative and qualitative studies conducted during 2004, including: online surveys (of all the teachers involved), routine data from the portal and semi‐structured interviews in 40 schools in all six countries.     

Attention performance in young adults with learning disabilities

Attention acts as the mind's “gatekeeper” by regulating and prioritizing the stimuli processed by the central nervous system. It is essential for cognitive performance, memory, and behavior, and we know that even slight deficiencies in attention compromise learning. Basic neuroscience research further indicates that attention consists of (fairly) independent subcomponents, which rely on distinct neural structures, and serve different functions in everyday behavior. Disturbances of brain function, such as those suggested to be related to learning disabilities, may lead to different patterns of attention performance (i.e., some attention systems may work sufficiently well, while others are substantially impaired). The present experiment describes a pilot study that aimed to characterize the extent and range of individual variations in attention performance in persons classified as learning disabled. Specifically, we tested the hypothesis that attention is not uniformly impaired in these individuals. Rather, we expected some subcomponents to be more severely impaired than others, and substantial heterogeneity in the individual “deficit patterns.”The Test of Everyday Attention (TEA) was used to assess visual selective attention, attentional switching, sustained attention, and auditory–verbal working memory in students with nondyslexic learning disability (LD group) and matched controls. The group comparison revealed a significantly weaker performance in the LD group. Analysis of subtest-specific scaled scores further indicated great individual differences in the performance pattern. Thus, in each student with LD, we found normal performance in at least two subtests, while other subcomponents where severely impaired. The study supports the idea of differential attention deficits in the learning disabled, and suggests individual patterns of “strengths and weaknesses.” Taking the relationship of attention and learning into account, this finding is important with respect to the design of individual learning programs and the teaching techniques chosen for the acquisition of skills and knowledge.     

Case studies of learning objects used in school settings

The purpose of this study was to investigate the role and characteristics of virtual learning objects in selected classroom cases. Four Finnish cases represented such pedagogical approaches as student‐centeredness, process orientation and collaborative inquiry. The case study approach enabled the investigation of concrete practices in using learning objects in ordinary classroom settings. The goal of the study was to examine the interrelatedness of the teachers’ pedagogical practices with characteristics and affordances of the learning objects, in order to understand how learning objects can support the development of advanced pedagogical practices in schools. The data used were qualitative, consisting of the participating teachers’ agendas, and observations and video recordings during classroom sessions. The results indicate that the learning objects were mostly used as exploration tools, information sources, assessment models and objects of discussion. An expert‐like use of knowledge was characteristic in the pedagogical settings, especially when the teacher was experienced in using ICT in teaching. However, not all the learning objects supported such practices, thus preventing a teacher from reaching intended pedagogical aims.     

An online authoring tool for creating activity-based learning objects

As higher education increasingly relies on e-learning, the need for tools that will allow teachers themselves to develop effective e-learning objects as simply and quickly as possible has also been increasingly recognized. This article discusses the design and development of a novel tool, Enook (Evolutionary note book), for creating activity-based learning objects (LOs). This tool has three general foci: 1) creation of various activity-based objects for experimental learning or learning by doing while simultaneously offering as many learning resources as a real e-book that services as both a textbook and a notebook, dual functions that paperback books can never provide; 2) management of all aspects of live instructor-led classroom training in a network environment, such the Web and or a mobile network; 3) facilitated use of data on students’ progress to monitor their understanding of the material and to provide other meaningful information through learning analytics.     

Transforming clinical imaging data for virtual reality learning objects

Advances in anatomical informatics, three‐dimensional (3D) modeling, and virtual reality (VR) methods have made computer‐based structural visualization a practical tool for education. In this article, the authors describe streamlined methods for producing VR “learning objects,” standardized interactive software modules for anatomical sciences education, from newer high‐resolution clinical imaging systems data. The key program is OsiriX, a free radiological image processing workstation software capable of directly reformatting and rendering volumetric 3D images. The transformed image arrays are then directly loaded into a commercial VR program to produce a variety of learning objects. Multiple types or “dimensions” of anatomical information can be embedded in these objects to provide different kinds of functions, including interactive atlases, examination questions, and complex, multistructure presentations. The use of clinical imaging data and workstation software speeds up the production of VR simulations, compared with reconstruction‐based modeling from segmented cadaver cross‐sections, while providing useful examples of normal structural variation and pathological anatomy.

Toward an instructional design model based on learning objects

The present moment in the history of higher education requires setting strategies and specific action plans to guarantee a place in the highly competitive and demanding world scenario. The incorporation of information and communication technologies is one of the feasible paths to be considered, but this requires formulating proposals insuring appropriate use of said technologies seeking improvement of education quality. For this purpose, Universidad de La Sabana has developed an instructional design model based on learning objects.     

Design of learning objects for concept learning: effects of multimedia learning principles and an instructional approach

Literature suggests using multimedia learning principles in the design of instructional material. However, these principles may not be sufficient for the design of learning objects for concept learning in mathematics. This paper reports on an experimental study that investigated the effects of an instructional approach, which includes two teaching techniques – (a) variation theory and (b) representations of subject matter – on the design of learning objects for secondary school algebra concept learning. The results of this study showed that the experimental group performed significantly better than the control group on algebra learning achievement. The results also showed that only the experimental design with the addition of the instructional approach resulted in higher-order mathematical thinking skills and improved procedural skills of the students. Further analysis reveals that concept learning was simplified when multimedia learning principles were applied and the information was presented by the instructional approach.
