Learning through question and answer interactions on the web

© 2002 IEEE. The paper discusses the use of a question and answer section of a discussion board on a computer-mediated web conferencing tool, and the way in which this facility fits with ideas of social learning. A description is provided of how learning was developed through questions and answers in this subject and insights are shared regarding the various uses of this facility by the students. Issues related to participation, peer misconceptions and teacher intervention are raised and discussed

An In-Class Role-Playing Activity to Foster Discussion and Deeper Understanding of Biodiversity and Ecological Webs

In a general sense, biodiversity is an intuitively simple concept, referring to the variety of Earth’s organisms. Ecologists, however, conceptualize biodiversity in a more nuanced, multidimensional way to reflect the enormous diversity of species, niches, and interspecific interactions that generate spatiotemporal complexity in communities. Students may not fully comprehend or appreciate this deeper meaning if they fail to recognize the full range of species in a community (e.g., the often-ignored microbes and small invertebrates) and how their varied interactions (e.g., mutualism, parasitism) and activities (e.g., ecosystem engineering) affect an ecosystem’s emergent structure (e.g., food webs) and function (e.g., decomposition). To help students learn about biodiversity and complex ecological webs, a role-playing activity was developed in which students “become” a different species (or resource) that they investigated for homework. In class, students work in small groups to “meet” other species in their community and, as appropriate for their roles, “consume” or “interact” with each other. As they make intraspecific connections, students collectively create an ecological web diagram to reveal the structure of their community’s relationships. This diagram is used for further exploration and discussion about, e.g., trophic cascades, non-trophic interactions, ecosystem engineering, and species’ effects on the movement of energy and nutrients. This inquiry-based activity has been observed to sustain student engagement and yield productive discussions and positive responses. Further, qualitative assessment indicates that students’ knowledge about biodiversity and ecological interactions improves after the activity and discussions, suggesting that students benefit from acting in and constructing their own ecological webs

Between the Lines: documenting the multiple dimensions of computer supported collaborations

When we consider the possibilities for the design and evaluation of Computer Supported Collaborative Learning (CSCL) we probably constrain the CS in CSCL to situations in which learners, or groups of learners collaborate with each other around a single computer, across a local intranet or via the global internet. We probably also consider situations in which the computer itself acts as a collaborative partner giving hints and tips either with or without the addition of an animated pedagogical agent. However, there are now many possibilities for CSCL applications to be offered to learners through computing technology that is something other than a desktop computer, such as the TV or a digital toy. In order to understand how such complex and novel interactions work, we need tools to map out the multiple dimensions of collaboration using a whole variety of technologies. This paper discusses the evolution of a documentation technique for collaborative interactions from its roots in a situation where a single learner is collaborating with a software learning partner, through its second generation: group use of multimedia, to its current test-bed: young children using digital toys and associated software. We will explore some of the challenges these different learning situations pose for those involved in the evaluation of collaborative learning

INCORPORATING WEB TECHNOLOGY IN FACE TO FACE COOPERATIVE LEARNING IN AN ENGINEERING COURSE

Traditional and monologue type of teaching and learning environment has been at the saturated stage. The teachers and students have shown their indifferences toward teaching and learning process. New approach, which requires students’ involvement in learning process, was introduced. Peer based learning activities through face-to-face interaction have been introduced to students. Variety of learner centered learning activities was developed and it has contributed in developing new learning culture to the students, i.e. collaborative and shared out attitude towards each other. Applying the Web Technology to this cooperative learning environment promotes more active and personal learning experiences to each individual student. Through threaded discussion facility students are able to evaluate, comment, share and enrich other ideas, opinions and problems. Web technology supports the face-to-face cooperative learning, as students are able to keep their group and class learning activities on beyond their scheduled formal class meeting. Variety teaching-learning scenarios certainly play prominent role to this group activity

Constructing Datasets for Multi-hop Reading Comprehension Across Documents

Most Reading Comprehension methods limit themselves to queries which can be answered using a single sentence, paragraph, or document. Enabling models to combine disjoint pieces of textual evidence would extend the scope of machine comprehension methods, but currently there exist no resources to train and test this capability. We propose a novel task to encourage the development of models for text understanding across multiple documents and to investigate the limits of existing methods. In our task, a model learns to seek and combine evidence - effectively performing multi-hop (alias multi-step) inference. We devise a methodology to produce datasets for this task, given a collection of query-answer pairs and thematically linked documents. Two datasets from different domains are induced, and we identify potential pitfalls and devise circumvention strategies. We evaluate two previously proposed competitive models and find that one can integrate information across documents. However, both models struggle to select relevant information, as providing documents guaranteed to be relevant greatly improves their performance. While the models outperform several strong baselines, their best accuracy reaches 42.9% compared to human performance at 74.0% - leaving ample room for improvement.Comment: This paper directly corresponds to the TACL version (https://transacl.org/ojs/index.php/tacl/article/view/1325) apart from minor changes in wording, additional footnotes, and appendice

Chatbots for learning: A review of educational chatbots for the Facebook Messenger

With the exponential growth in the mobile device market over the last decade, chatbots are becoming an increasingly popular option to interact with users, and their popularity and adoption are rapidly spreading. These mobile devices change the way we communicate and allow ever-present learning in various environments. This study examined educational chatbots for Facebook Messenger to support learning. The independent web directory was screened to assess chatbots for this study resulting in the identification of 89 unique chatbots. Each chatbot was classified by language, subject matter and developer's platform. Finally, we evaluated 47 educational chatbots using the Facebook Messenger platform based on the analytic hierarchy process against the quality attributes of teaching, humanity, affect, and accessibility. We found that educational chatbots on the Facebook Messenger platform vary from the basic level of sending personalized messages to recommending learning content. Results show that chatbots which are part of the instant messaging application are still in its early stages to become artificial intelligence teaching assistants. The findings provide tips for teachers to integrate chatbots into classroom practice and advice what types of chatbots they can try out.Web of Science151art. no. 10386

Interaction and effectiveness of corporate e-learning programmes

This study was conducted in a large Mexican organization running a virtual corporate university. It aimed to evaluate students’ perceptions of three types of interaction (learner–teacher, learner–content and learner–learner) and their views on the effectiveness of online courses in terms of satisfaction, learning and behaviours. Twenty-six employees who had studied at least one online course within the organization answered an online survey. Four of them were interviewed. Results show that: (1) Learners value their interaction with the content the most. (2) Online learning is generally perceived as an effective method for delivering corporate training. (3) There is no perceived relationship between online interactions and training effectiveness. The findings are limited to the specific context of the participating organization. Further research into online learning in corporate settings is needed to understand training interactions and changes in job performance
