The impact of social media on informal learning in museums

This paper posits that social networking can take a central role in learning in informal environments such as museums, libraries and galleries. It argues that social media offers young people agency previously unavailable in informal learning environments in order to explore complex responses to and participation with cultural content. The paper will consider transformations in digital literacy and the processes by which young learners can connect with knowledge in informal learning environments to become active cultural participants.

Die Wirkung sozialer Medien auf informelle Bildung in Museen

Dieses Papier postuliert, dass soziale Vernetzung eine zentrale Rolle im Lernen in informellen Umgebungen wie Museen, Bibliotheken und Galerien annehmen kann. Es behauptet, dass soziale Medien jungen Leuten als Agentur in informellen Lernumgebungen dienen können, die zuvor nicht verfügbar sind, um komplexe Antworten zu erkunden und Beteiligung mit kulturellem Inhalt zu erkennen. Die Autoren betrachten Transformationen in digitalen Fähigkeiten und den Prozessen, durch die junge Anfänger sich mit Wissen in anderen informellen Bildungsumgebungen verbinden können, um aktive kulturelle Teilnehmer zu werden.

L’impact des medias “sociaux” sur l’apprentissage informel dans les musées

Le présent article affirme que la mise en réseau humain peut jouer un rôle central pour l’apprentissage dans des environnements informels comme les musées,les bibliothèques et les galeries. Il avance que les medias “sociaux” offrent aux jeunes des moyens qui n’existaient pas auparavant dans les environnemetns d’apprentissage informels pour permettre d’explorer des réactions complexes et d’interagir avec le contexte culturel. Les auteurs examinent les mutations de la compétence numérique et les processus par lesquels les jeunes apprenants peuvent se brancher sur la connaissance dans des environnements d’apprentissage informels pour devenir des acteurs culturels dynamiques.

El impacto de los medios colectivos sobre el aprendizaje informal en los museos

Esta artículo postula que la creación de redes humanas puede desempeñar un papel central para el aprendizaje en entornos informales como los museos, las bibliotecas y las galerías. Apunta que los medios sociales ofrecen a los jovenes capacidades que antes no estaban asequibles dentro de los entornos de aprendizaje informal para explorar las respuestas complejas y interagir con el contexto cultural. Los autores consideran las transformaciones en el alfabetismo digital y los procesos a través de los cuales los jovenes alumnos pueden conectarse con los conocimientos dentro de esos entornos informales de aprendizaje para convertirse en actores culturales dinámicos.     

Assessing graduate assistant teacher communication concerns

The purpose of this study was to develop an instrument measuring teacher communication concern as experienced by graduate teaching assistants (GTAs). Two‐hundred and thirty‐three GTAs enrolled in a preservice orientation program completed two scales: a revised, expanded version of the Teacher Communication Concern scale and a 28‐item Concerns Checklist. Results indicate that GTAs experience eight somewhat interrelated types of concern: self, task, impact, role conflict, teaching, area knowledge, procedural knowledge, and time management. Furthermore, GTA variables of expected duties, prior teaching experience, newness to area, foreign born, and age are likely to predict differential types of concerns.     

Short lesson plan associated with increased acceptance of evolutionary theory and potential change in three alternate conceptions of macroevolution in undergraduate students

Undergraduates commonly harbor alternate conceptions about evolutionary biology; these alternate conceptions often persist, even after intensive instruction, and may influence acceptance of evolution. We interviewed undergraduates to explore their alternate conceptions about macroevolutionary patterns and designed a 2-h lesson plan to present evidence that life has evolved. We identified three alternate conceptions during our interviews: that newly derived traits would be more widespread in extant species than would be ancestral traits, that evolution proceeds solely by anagenesis, and that lineages must become more complex over time. We also attempted to measure changes in the alternate conceptions and levels of acceptance of evolutionary theory in biology majors and nonmajors after exposure to the lesson plan. The instrument used to assess understanding had flaws, but our results are suggestive of mixed effects: we found a reduction in the first alternate conception, no change in the second, and reinforcement of the third. We found a small, but significant, increase in undergraduate acceptance of evolutionary theory in two trials of the lesson plan (Cohen's d effect sizes of 0.51 and 0.19). These mixed results offer guidance on how to improve the lesson and show the potential of instructional approaches for influencing acceptance of evolution.     

Computer-assisted instruction to prevent early reading difficulties in students at risk for dyslexia: Outcomes from two instructional approaches

The relative effectiveness of two computer-assisted instructional programs designed to provide instruction and practice in foundational reading skills was examined. First-grade students at risk for reading disabilities received approximately 80 h of small-group instruction in four 50-min sessions per week from October through May. Approximately half of the instruction was delivered by specially trained teachers to prepare students for their work on the computer, and half was delivered by the computer programs. At the end of first grade, there were no differences in student reading performance between students assigned to the different intervention conditions, but the combined-intervention students performed significantly better than control students who had been exposed to their school’s normal reading program. Significant differences were obtained for phonemic awareness, phonemic decoding, reading accuracy, rapid automatic naming, and reading comprehension. A follow-up test at the end of second grade showed a similar pattern of differences, although only differences in phonemic awareness, phonemic decoding, and rapid naming remained statistically reliable.

The Pedagogy of Primary Historical Sources in Mathematics: Classroom Practice Meets Theoretical Frameworks

We analyze our method of teaching with primary historical sources within the context of theoretical frameworks for the role of history in teaching mathematics developed by Barbin, Fried, Jahnke, Jankvist, and Kjeldsen and Blomhøj, and more generally from the perspective of Sfard’s theory of learning as communication. We present case studies for two of our guided student modules that are built around sequences of primary sources and are intended for learning core curricular material, one on logical implication, the other on the concept of a group. Additionally, we propose some conclusions about the advantages and challenges of using primary sources in teaching mathematics.
