TY - JOUR A1 - Hermanns, Jolanda T1 - The task navigator following the STRAKNAP concept BT - Development, application, and evaluation of a new scaffold to support nonmajor chemistry students while solving tasks in organic chemistry JF - Journal of chemical education / Division of Chemical Education, Inc., American Chemical Society N2 - Educational Scaffolding was first mentioned in 1976 by Wood et al. Several examples for scaffolding in chemistry are also known from the literature. As written scaffolds, stepped supporting tools to support students while solving problems in organic chemistry were developed, applied, and evaluated. Although the students rated the tool as very helpful, a think-aloud study showed that the support given by this scaffold was not sufficient. As a further development of stepped supporting tools, task navigators were therefore developed, applied, and evaluated. This new scaffold gives tips on strategy, knowledge, and application of knowledge after the STRAKNAP concept. The evaluation of this tool shows that the students rated the tool as being very helpful. A think-aloud study showed that the scaffold supports the students while they solve a problem. Because of the stepwise construction of the task navigators and the providing of the knowledge needed for the application, the students can solve parts of the task successfully even if they do not solve all parts correctly; the students can always start from scratch. When students use the tool regularly, their knowledge of organic chemistry increases compared to students who did not use the tool at all. The task navigator is not only a scaffold for the content of the task but also for the development of methodological competences on the field of strategies and applying knowledge.

A main goal of the course was to enable the students to solve reaction mechanisms. To achieve the goals of the course, several games were specially designed and used. The course was conducted at a German university with ca. 30 students who participated voluntarily. The course was evaluated by several tools: students' products were collected in the course, there were two pre/post-tests, and additionally, interviews on the strategy of designing reaction mechanisms were conducted. The performance of the teacher and the self-assessment of the students were also part of the evaluation. The results of the written exam were compared with the results of the bachelor chemistry major students. The course "Training OC" was rated very well by the students. They were of the opinion that they learned the application of basic concepts taught in this course. This is supported by the results of the evaluation and the written exams. The course concept of Training OC will therefore become a permanent part of the course "Organic Chemistry I" which will be redesigned for the next round in 2020-21.

Therefore, the current study investigates the meaning of the medium-that means video compared to text-based reflections-and the type of situations-that are positive or difficult situations of teaching-and relations to preservice teachers' reflective processes. Also, levels of reflections are investigated. In our study, we examine reflections of 55 preservice teachers using a quasi-experimental design. Qualitative content analysis shows that preservice teachers reflect deep levels of teaching while using videos of peers in situations that they evaluated as positive experiences in school. However, when rating situations that were evaluated as challenging preservice teachers reflected deep levels when using videos of peers as well as text-based reflections. Implications of the study for teacher training in reflection are discussed. N2 - Die Reflexion praktischer Unterrichtserfahrungen ermöglicht es Lehramtsstudierenden theoretische Wissensaspekte und praxisrelevante Erkenntnisse miteinander zu verknüpfen. Die vorliegende Studie untersucht die Bedeutung des Mediums der Reflexion (eigenes Video vs. fremdes Video vs. Protokoll) sowie der Art der reflektierten Unterrichtssituation (positiv vs. herausfordernd) für die Reflexionsprozesse Lehramtsstudierender. Darüber hinaus wird untersucht, auf welchen Ebenen (Basal‑, Sicht- und Tiefenstrukturen) das Unterrichtsgeschehen reflektiert wird. Datengrundlage der quasi-experimentellen Studie sind Unterrichtsreflexionen von 55 Lehramtsstudierenden, die inhaltsanalytisch ausgewertet wurden. Die Ergebnisse zeigen, dass Lehramtsstudierende die Tiefenstrukturen des Unterrichts reflektieren, wenn die Reflexion von Situationen, die als positiv erlebt wurden, anhand fremder Unterrichtsvideos geschieht. Bei der Reflexion von herausfordernden Unterrichtssituationen werden Tiefenstrukturen sowohl anhand von fremden Videos als auch anhand von Protokollen reflektiert. Die Implikationen der Ergebnisse für die Lehrkräftebildung werden im Hinblick auf die Reflexion von Unterrichtspraxis diskutiert.

BT - eine Analyse von Beiträgen der Zeitschrift für Erziehungswissenschaft BT - an analysis of contributions to the journal JF - Zeitschrift für Erziehungswissenschaft : ZfE N2 - The present study examines articles published in Zeitschrift fur Erziehungswissenschaft (ZfE-Journal of Educational Sciences) between 1998 and 2017, to discover whether the thematic focus of the articles it published during this period changed over time. To do this, we scrutinized articles in four consecutive five-year periods: 1998-2002, 2003-2007, 2008-2012, 2013-2017. Using the titles and abstracts of 821 articles published between 1998 and 2017, we conducted a quantitative text analysis and identified the most frequent and most characteristic bigrams that emerged during these periods. In addition, we looked at whether specific word stems (e.g., "erziehungswissenschaft", "bildungsforsch", "didakt") began to occur more frequently over the two decades under study. Finally, we used the text mining tool Leximancer (TM) to construct concept maps that point to the semantic structure of the topics and key concepts in the analyzed articles. The results indicate that, over the course of this twenty-year period, the ZfE predominantly published empirical articles with a focus on the social aspects of education, but that its focus on research into general pedagogy decreased in frequency. N2 - er vorliegende Beitrag beschäftigt sich mit den Publikationen, die in der Zeitschrift für Erziehungswissenschaft (ZfE) in den Jahren 1998–2017 veröffentlicht wurden. Angesichts der Veränderungen in der erziehungswissenschaftlichen Forschungslandschaft in der jüngeren Vergangenheit untersuchen wir, inwiefern sich eine veränderte Schwerpunktsetzung auch in den Beiträgen der ZfE nachweisen lassen. Dazu führen wir zunächst eine quantitative Textanalyse durch und identifizieren die häufigsten sowie die charakteristischen Bigramme (Zweiwortsequenzen) in vier aufeinanderfolgenden Fünfjahres-Abschnitten (1998–2002, 2003–2007, 2008–2012, 2013–2017). Zudem prüfen wir, inwiefern bestimmte Wortstämme (bspw. „erziehungswissenschaft“, „bildungsforsch“, „didakt“) über die Jahre hinweg häufiger auftreten. Schließlich erstellen wir mit dem Textmining Tool Leximancer™ concept maps, die Hinweise auf die semantische Struktur der Themengebiete und Schlüsselkonzepte geben. Die Ergebnisse deuten darauf hin, dass im gesamten Zeitraum mehrheitlich Beiträge mit empirischem Fokus publiziert wurden, ein inhaltlicher Fokus auf sozialen Aspekten von Bildung lag und die Beschäftigung mit der allgemeinen Erziehungswissenschaft abnahm.

BT - Evidence from a large scale study JF - Frontiers in education N2 - This study investigates the relationship between teacher quality and teachers’ engagement in professional development (PD) activities using data on 229 German secondary school mathematics teachers. We assessed different aspects of teacher quality (e.g. professional knowledge, instructional quality) using a variety of measures, including standardised tests of teachers’ content knowledge, to determine what characteristics are associated with high participation in PD. The results show that teachers with higher scores for teacher quality variables take part in more content-focused PD than teachers with lower scores for these variables. This suggests that teacher learning may be subject to a Matthew effect, whereby more proficient teachers benefit more from PD than less proficient teachers.
