Learning Object (LO) is a representation of interactive content that are used to enrich e-learning activities. The goals of this case study were to evaluate accessibility and compatibility factors from learning objects that were produced by using BINUS E-learning Authoring Tool. Data were compiled by using experiment to 30 learning objects by using stratified random sampling from seven faculties in undergraduate program. Data were analyzed using accessibility and compatibility tests based on Web Content Accessibility Guidelines 2.0 Level A. Results of the analysis for accessibility and compatibility tests of Learning Objects was 90% better than average. The result shows that learning objects is fully compatible with major web browser. This paper also presents five accessibility problems found during the test and provide recommendation to overcome the related problems. It can be concluded that the learning objects that were produced using BINUS E-learning Authoring Tool have a high compatibility, with minor accessibility problems. Learning objects with a good accessibility and compatibility will be beneficial to all learner with or without disabilities during their learning process. Index Terms—accessibility, compatibility, HTML, learning object, WCAG2.0, web

In literature, there are a number of indexes suggested that serve as the indicator of commonality among product components, modules and variants. However, as these elements are increasingly interconnected with aspects other than the component view, the existing commonality metrics are unable to effectively model these aspects due to their limitation in capturing relevant information for analysis. Therefore, there exists a need to consider multiple design and manufacturing aspects in commonality metrics so that a comprehensive view of the commonality among product variants can be presented. In the current representation schemes proposed for product family modeling, ontology is one of the most promising ones to model the complex semantic relations among various elements in a product family. Nevertheless, the research and application of ontology in the analysis of a product family has so far received little attention. In this paper, we proposed a framework to generate a semantically annotated multi-facet product family ontology. Using a case study of a laptop computer family, we suggest and demonstrate a new commonality analysis approach based on the semantically annotated multi-facet laptop product family ontology. Together with a new method of deriving product variants based on the aforementioned ontology, our approach illustrates the merits of using semantic annotation in assisting ontology based product family analysis.

In the context of distance education, one aspect materialized by educational technology is through the use of learning objects (LO). These elements can be defined as educational digital resources that favor students' interaction with many languages and different media. This chapter aims to present two scenarios. The first one involves a case study about the production of didactic content. This study will focus on teaching and will consist of showing the rationale behind the content production method used by the company and the methodology used in the construction of learning objects in the context of a learning unit. The second scenario will consist of students' views by means of a survey conducted with more than 4 thousand students from higher education institutions (HEIs) from different regions of Brazil who consume the content and make use of the learning objects. The reflections point to the pedagogical potential of learning objects but also to concerns in view of great challenges posed by hybrid teaching within the Brazilian scenario.

This chapter provides an in depth discussion of the issues involved in integrating learning design and learning objects into generic Web sites. It has a dual focus and consists of two parts: the first part outlines and critiques the notion of the Net Generation and its implications for learning design, while the second part is based on a case study of a generic academic learning support Web site and allows for the testing of some of the theoretical assumptions about the Net Generation. Informed by empirical research, this chapter concludes by offering suggestions on ways to exploit convergent possibilities of integrating learning design and learning objects in a Web environment, while paying careful attention to divergent capabilities of students targeted in such an environment.

Abstract: Sustainability transitions require societal change at multiple levels ranging from individual behavioral change to community projects, businesses that offer sustainable products as well as policy-makers that set suitable incentive structures. Concepts, methods and tools are currently lacking that help to initiate and design transition governance processes based upon an encompassing understanding of such diverse interactions of actors and intervention points. This article presents a methodological framework for the initiation and design of transition governance processes. Based upon a conceptualization of sustainability transitions as multilevel learning processes, the methodological framework includes participatory modeling, a systematic literature review and governance system analysis to identify social units (learning subjects and contexts), challenges (learning objects) and intervention points (learning factors) relevant for initiating case-specific transition governance processes. A case study on sustainable food systems in Ontario, Canada is provided to exemplify the application of the methodological framework. The results demonstrate the merit of combining stakeholder-based and expert-based methods, as several learning factors identified in the participatory process could not be found in the general literature, and vice versa. The methodological framework allowed for an integrated analysis of the diversity of existing initiatives in the case study region and specific intervention points to support place-based sustainability innovations. Initiators of transition governance processes can use the results by designing targeted interventions to facilitate and coordinate existing initiatives or by setting new impulses through purposeful action.

Harman & Koohang (2005) stated that a learning object “ .. is not merely a chunk of information packaged to be used in instructional settings. A learning object, therefore, can include anything that has pedagogical value - digital or non-digital such as a case study, a film, a simulation, an audio, a video, an animation, a graphic image, a map, a book, or a discussion board so long as the object can be contextualized by individual learners. The learner must be able to make meaningful connections between the learning object and his/her experiences or knowledge he/she previously mastered. “ The above definition asserts that a learning object must have “pedagogical value” and that a learning object is 1) anything digital or non-digital such as a film, a simulation, or a case study, and 2) the ability of the learner to contextualize the object, i.e., the learner is capable of making “meaningful connections” between the object and his/her previous experiences and/or knowledge. Once the contextualization occurs, the object will have “pedagogical value” and it no longer merely an object, it is a learning object. Can all objects be contextualized? Is it necessary for all objects to be contextualized? What shall one call an “object” that is retrieved (and may even have some value other than pedagogical value and/or use) from an open access or commercial learning objects repository labeled as a “learning object” with no pedagogical value? If these objects are not learning objects, but have some sort of value and use, how shall one refer to these objects? Perhaps “informing objects”?
