Testing the model-observer similarity hypothesis with text-based worked examples

Example-based learning is a very effective and efficient instructional strategy for novices. It can be implemented using text-based worked examples that provide a written demonstration of how to perform a task, or (video) modelling examples in which an instructor (the ‘model’) provides a demonstration. The model-observer similarity (MOS) hypothesis predicts that the effectiveness of modelling examples partly depends on the degree to which learners perceive the models to be similar to them. It is an open question, however, whether perceived similarity with the person who created the example, would also affect learning from text-based worked examples. Therefore, two experiments were conducted to investigate whether MOS would also play a role in learning from worked examples. In Experiment 1 (N = 147), students were led to believe via pictures and a short story that the worked examples were created by a male or female peer student. Males showed higher performance and confidence, but no effects of MOS on learning were found. In Experiment 2 (N = 130), students were led to believe that a peer student or a teacher created the examples. Again, no effects of MOS were found. These findings suggest that the perceived origin of text-based worked examples is not important for learning.     

Mental health problems of Dutch youth with hearing loss as shown on the Youth Self Report

The prevalence OF mental health problems among youth with hearing loss was assessed with an adjusted version of the Dutch rendition of the Youth Self Report, or YSR (Achenbach, 1991). The sample totaled 202 youth, aged 11-18 years, with auditory disabilities. The prevalence rates of externalizing problems, internalizing problems, and moderate to severe overall mental health problems were found to be 2-3 times higher than in a normative sample. Deaf participants scored significantly higher than hard of hearing participants in these areas. Main-streamed participants scored significantly lower than peers in schools for the deaf or for the hard of hearing. Participants with low IQ scores showed significantly more internalizing and social problems than those with moderate to high scores. The adjusted YSR is recommended for screening in schools and in mental health services for youth with hearing loss for prevention and early intervention.     

Place-based education from three perspectives

Abstract

This article examines the perception of the Czech place-based education program School for Sustainable Development from the perspectives of the participating students, teachers, and representatives of the local municipalities. The study is based on an analysis of paired or group interviews with 47 students, 7 teachers, and 6 representatives. The findings show that while the teachers perceived the process of the students’ involvement in planning and conducting a community-based project as highly participative, the students’ opportunities to shape the process through making their own decisions were rather limited and the teachers kept control over important parts of the process to themselves. While the cooperation of the schools with their respective municipalities was appreciated by most of the respondents, several barriers have been identified. Participation in the project has likely increased the teachers’ self-effectiveness, developed the students’ interpersonal competence, and improved the atmosphere at the schools involved.

The Merits of Using “Worldview” in Religious Education

This article aims to argue that worldview is a useful concept in religious education because of its encompassing character. In the first part of the article three essential characteristics of “worldview” are distinguished: “worldview” includes religious and secular views; a distinction between organized and personal worldviews should be made; and existential questions are a necessary part of “worldview.” The second part of the article demonstrates how two articles about Grimmitt's distinction between learning about and from religion benefit from using “worldview” and how the authors can address their points more clearly by using the concept and its three essential characteristics.     

Assessing Teachers’ Science Content Knowledge: A Strategy for Assessing Depth of Understanding

One of the characteristics of effective science teachers is a deep understanding of science concepts. The ability to identify, explain and apply concepts is critical in designing, delivering and assessing instruction. Because some teachers have not completed extensive courses in some areas of science, especially in middle and elementary grades, many professional development programs attempt to strengthen teachers’ content knowledge. Assessing this content knowledge is challenging. Concept inventories are reliable and efficient, but do not reveal depth of knowledge. Interviews and observations are time-consuming. The Problem Based Learning Project for Teachers implemented a strategy that includes pre-post instruments in eight content strands that permits blind coding of responses and comparison across teachers and groups of teachers. The instruments include two types of open-ended questions that assess both general knowledge and the ability to apply Big Ideas related to specific science topics. The coding scheme is useful in revealing patterns in prior knowledge and learning, and identifying ideas that are challenging or not addressed by learning activities. The strengths and limitations of the scoring scheme are identified through comparison of the findings to case studies of four participating teachers from middle and elementary schools. The cases include examples of coded pre- and post-test responses to illustrate some of the themes seen in teacher learning. The findings raise questions for future investigation that can be conducted using analyses of the coded responses.     

Encouraging Prospective Teachers to Engage Friends and Family in Exploring Physical Phenomena

Involving people outside of a science course can foster learning for students enrolled in the course. Assignments involving friends and family provided such opportunities in an undergraduate physics course for prospective teachers. These assignments included reflecting upon prior experiences, interviewing friends and family members, engaging them in exploring physical phenomena, and teaching them with relevant websites. The six strands of science learning articulated in Learning Science in Informal Environments (National Research Council in Learning science in informal environments: People, places, and pursuits. National Academies Press, Washington, DC, 2009) provided a framework for analyzing the prospective teachers’ responses. Through such assignments, the instructor created opportunities for the prospective teachers to use and build upon knowledge learned in class as well as to gain confidence and experience in facilitating the learning of others.     

Network Applications for Group-Based Learning: Is More Better?

Group-based learning is being introduced into many settings in higher education. Is this a sustainable development with respect to the resources required? Under what conditions can group-based learning be applied successfully in distance education and in increasingly flexible campus-based learning? Can networked support facilitate and enrich courses where group-based learning is applied? These questions formed the basis of the motivation for the research project whose main results are presented here. The goals set for the research were the identification of problems associated with the planning, operationalisation, and monitoring of group tasks in group-based learning in higher education, and the identification of networked support options which, in combination with appropriate instructional decisions, have the potential to remedy these problems. The solutions identified were tested in the context of three case studies.     

Promoting Self-Directed Learning in Simulation-Based Discovery Learning Environments Through Intelligent Support

Providing learners with computer-generated feedback on their learning process in simulation-based discovery environments cannot be based on a detailed model of the learning process due to the “open” character of discovery learning. This paper describes a method for generating adaptive feedback for discovery learning based on an “opportunistic” learning model that takes the current hypothesis of the learner and the experiments performed to test this hypothesis as input. The method was applied in a simulation–based learning environment in the physics domain of collisions. Additionally, the method was compared to an environment in which subjects received predefined feedback on their hypotheses, not taking the experimentation behavior into account. Results showed that overall both groups did not differ on knowledge acquired. A further analysis indicated that, in their learning processes, the learners in the experimental condition built upon their intuitive knowledge base, whereas the learners in the control condition built upon their conceptual knowledge base. In addition, measures of the learning process showed that the subjects in the experimental condition adopted a more inquiry-based learning strategy compared to the subjects in the control condition. We concluded, therefore, that providing learners with adaptive feedback had a different and beneficial effect on the learning process compared to more traditional predefined feedback.     

Designing the Internet of Things for learning environmentally responsible behaviour

We present two designs in the area of the Internet of Things, utilizing the ontology-driven Smart Objects For Intelligent Applications (SOFIA) Interoperability Platform (IOP). The IOP connects domestic objects in the physical world to the information world, allowing for coaching the behaviour of, or raising awareness in, domestic energy consumption. The concept and architecture of the SOFIA IOP is introduced, in which the domestic objects are knowledge processors connected to a semantic information broker. This broker, using a blackboard design pattern, ontologies, and semantic web technologies, enables interoperability among both digital and physical entities. The two designs based on the SOFIA IOP are presented as examples for coaching with and learning from the Internet of Things. Although both designs are in the area of domestic energy consumption, they can be seen as good starting points towards broader areas of ubiquitous learning enabled by the Internet of Things.
