Investigation of students' perceptions and opinions on the use generative artificial intelligence (GenAI) in education is a topic gaining much interest. Studies addressing this are typically conducted with large heterogeneous groups, at one moment time. However, how students perceive GenAI tools can potentially depend many factors, including their background knowledge, familiarity tools, learning goals policies courses they taking.In study we explore following computing for...
Textbooks are educational documents created, structured and formatted by domain experts with the primary purpose to explain knowledge in a novice. Authors use their understanding of when structuring formatting content textbook facilitate this explanation. As result, structural elements textbooks carry implicitly encoded authors. Our paper presents an extensible approach towards automated extraction models from enrichment additional links (both internal external). The themselves essentially...
Textbooks are educational documents created, structured and formatted by domain experts with the main purpose to explain knowledge in a novice. Authors use their understanding of when structuring formatting content textbook facilitate this explanation. As result, structural elements textbooks carry implicitly encoded authors. Our paper presents an extendable approach towards automated extraction from taking into account rules internal structure. We focus on PDF as most common representation...
Textbooks are educational documents created, structured and formatted in a way that facilitates understanding. Most digital textbooks released as mere copies of their printed counterparts. We present mechanism extracts knowledge models from enriches content with additional links (both internal external). The essentially become hypertext where individual pages annotated important concepts the domain. also show extracted can be automatically connected to Linked Open Data cloud, which helps...
A typical index at the end of a textbook contains manually-provided vocabulary terms related to content textbook. In this paper, we extend our previous work on extraction knowledge models from digital textbooks. We are taking more critical look and present mechanism for classifying according their domain specificity: core concept, an in-domain concept domain, foreign domain. link extracted DBpedia leverage aggregated linguistic structural information textbooks construct prune domain-specific...
Quality of learning objects metadata, in many respects, defines the quality an adaptive environment presenting these to a student. Metadata inconsistencies and gaps may be cause various problems: from system malfunction ineffective experiences. In this paper, we propose intelligent rigorous mechanism for detecting metadata collections content. The converts into OWL2 ontology, detects logical conflicts using Semantic Web reasoning techniques generates human-readable explanations author...
Este artículo describe un enfoque innovador para la extracción de modelos conocimiento a partir libros texto y su aplicación en los negocios. A través proceso detallado, que incluye extracción, vinculación, enriquecimiento, análisis formalización, se crean alta calidad. es el resultado una investigación doctoral, este ofreceun resumen ejecutivo misma. Los creados tienen aplicaciones educación, pero también pueden ser usados potencialmente ámbito empresarial. En ese sentido, explora las...

Isaac Alpizar-Chacon is an assistant professor in the Software Technology for Learning and Teaching group at Department of Information Computing Sciences, Utrecht University. In addition to his primary role, he also associate Instituto Tecnológico de Costa Rica. His research interests focus on impact GenAI tools computing education, integration these into classroom, teaching learning computational thinking skills, knowledge extraction. Dr. holds a MSc degree Computer Science from Saarland...
There are a large number of educational resources available on the Internet through different repositories. However, authenticity methods learning objects has not been widely adopted by repositories, making it difficult to verify authors content. To solve this problem, our goal is aid users and have trusted verification versioning applying digital signatures into lifecycle objects. In propose, after object uploaded repository, author presents his/her certificate, special LOM record created...
