Ratings of usability of didactic models: a comparative case study in Croatia and Germany

The study refers to the unfavourable reputation and status of general didactics as well as its decreasing importance in teacher education. This is a result of poor performance achieved in international tests by students. They score low on knowledge and arguments, and empirical studies indicate that didactic models are useless. In view of the above problem, the aim of this article is to examine the validity of the argument that didactic models are useless. It is necessary to examine if general didactics are being in an unfavourable position along with its possible successors in the international context. In order to achieve that, we conducted an empirical study into the usability of didactic models for lesson planning in Croatia and compared it with the results obtained in previous research in Germany. The term usability means the advantages of theory in practice. On the basis of the results of the empirical study, we concluded that didactic models are not generally unusable. Additionally, they are different according to their usability. These results open a path for further research on this topic in the international context.     

Technology intensity and agglomeration economies

This article investigates the relationship between industry technology intensity and the impacts of agglomeration economies on industrial growth. Many recent studies suggest the actual economic impacts of different forms of agglomeration economies depend on industrial characteristics such as technology intensity, but systematic empirical evidence is still lacking. To fill this gap, we analyze employment data covering all 3-digit NAICS industries of U.S. counties. The results confirm that technology-intensive industries are more likely to benefit from Jacobs spillovers as measured by related variety, while sectors with low technology intensities can better benefit from MAR spillovers as measured by regional specialization.     

Learning with videos vs. learning with print: The role of interactive features

Two complementary studies, one in the laboratory and one in the field, compared the usage patterns and the effectiveness of interactive videos and illustrated textbooks when German secondary school students learned complex content. For this purpose, two videos affording different degrees of interactivity and a content-equivalent illustrated textbook were used. Both studies showed that in contrast to previous studies working with non-interactive videos, the effectiveness of interactive videos was at least comparable to that of print, probably due to the possibilities provided for self-regulated information processing. It was shown that the interactive features of the videos were used spontaneously. However, features enabling micro-level activities, such as stopping the video or browsing, seemed to be more beneficial for learning than features enabling macro-level activities, such as referring to a table of contents or an index. This finding is explained by students’ misconceptions about the use of features enabling macro-level activities.     

Automatic,semantics-based indexing of natural language texts for information retrieval systems

The fundamental idea of the work reported here is to extract index phrases from texts with the help of a single word concept dictionary and a thesaurus containing relations among concepts. The work is based on the fact, that, within every phrase, the single words the phrase is composed of are related in a certain well denned manner, the type of relations holding between concepts depending only on the concepts themselves. Therefore relations can be stored in a semantic network. The algorithm described extracts single word concepts from texts and combines them to phrases using the semantic relations between these concepts, which are stored in the network. The results obtained show that phrase extraction from texts by this semantic method is possible and offers many advantages over other (purely syntactic or statistic) methods concerning preciseness and completeness of the meaning representation of the text. But the results show, too, that some syntactic and morphologic “filtering” should be included for effectivity reasons.     

Believing in Neuromyths Makes Neither a Bad Nor Good Student‐Teacher: The Relationship between Neuromyths and Academic Achievement in Teacher Education

Neuromyths have been discussed to detrimentally affect educational practice, but the evidence for this assumption is still very scarce. We investigated whether 255 student‐teacher' beliefs in neuromyths are related to their academic achievement (overall grade point averages and first‐year practical courses). Believing or rejecting neuromyths that make no direct assumptions about learners' educability was not related to academic achievement. Believing in neuromyths that explicitly deny the educability of learners was only marginally related to academic achievement. We conclude that self‐reported beliefs in neuromyths do not differentiate between high‐ and low‐achieving initial teacher education students.     

Evaluation of Online, On-Demand Science Professional Development Material Involving Two Different Implementation Models

This report presents pilot-test results for a science professional development program featuring online, on-demand materials developed by the National Science Teachers Association. During the spring 2006 semester, 45 middle school teachers from three different school districts across the United States participated in a professional development program designed to facilitate content knowledge and skills in the area of Newtonian force and motion. Participants from one of the school districts experienced a full-day instructor-led workshop along with two web-based seminars with a content-area expert. This was followed by a 4-week period of time in which they had access to self-directed, online, on-demand instructional materials that included activities, information, simulations, examples, and practice with immediate feedback over the targeted outcomes. Participants from the two other school districts only had access to the online materials with no instructor-led experience. This report documents positive gains in achievement as well as levels of confidence in teaching the material within all of the professional development groups. Data about the use of specific features within the online material are included, as well as completion rates and attitude survey results. Recommendations for future study are also included.     

An Insight into Professional Identity Formation: Qualitative Analyses of Two Reflection Interventions During the Dissection Course

The professional behavior of future doctors is increasingly important in medical education. One of the first subjects in the curriculum to address this issue is gross anatomy. The Tuebingen Medical Faculty implemented a learning portfolio and a seminar on medical professionalism during the dissection course. The aims of this research project are to get an overview of how students form a professional identity in the dissection course and to compare the content of both their oral and written reflections on the course. A qualitative analysis was conducted of the oral and written reflections on the dissection laboratory experience. This study was conducted during winter term 2013/2014 with a cohort of 163 participants in the regular dissection course. Written reflection texts (from n = 96 students) and audio recordings from four oral reflection seminar discussions (with n = 11 students) were transcribed and deductively categorized with Mayring’s qualitative content analysis method. Both qualitative analyses show that students reflected on many topics relevant to professional development, including empathy, respect, altruism, compassion, teamwork, and self-regulation. Quantitative analysis reveals that students who attended the oral reflection wrote significantly more in their written reflection than students who did not. There is, however, no difference in the reflection categories. Reflection content from students corresponds with categories derived from existing competency frameworks. Both the seminar (oral reflections) and the learning portfolio (written reflections) present excellent opportunities to foster professional development during anatomy education; the key is using them in conjunction with the dissection course.
