Images of Science Linked to Labwork: A Survey of Secondary School and University Students

This paper presents findings about the images of science drawn upon in laboratory work, by upper secondary and university students, in academic streams with a science focus. Data were collected through four written questions, administered to a total of 368 students. The questions all required students to comment on laboratory investigations carried out by research scientists or by science students. We show that students' reasoning has an epistemological and an ontological dimension, and that it often differs significantly from accepted perspectives on the nature of science. The issue for teaching appears to be showing students what counts (and what does not count) as appropriate reasoning in actual situations. In other words, explicit teaching about the various relationships that can exist between theory and data would transform labwork towards a more critical process that involves making and justifying decisions.     

Pädagogisierung und Systembildung

Eine M?glichkeit, das Verh?ltnis von P?dagogik und Gesellschaft zu beschreiben, scheint im Begriff P?dagogisierung zu liegen. In der jüngeren Diskussion lassen sich zwei Konzeptualisierungen dieses Begriffs unterscheiden. P?dagogisierung kann erstens als Transformation sozialer Probleme in p?dagogische Probleme gedeutet werden. Hier wird unterstellt, dass soziale Probleme durch die Einwirkung auf Menschen mit den Mitteln institutionalisierter Erziehung und Bildung zu bearbeiten seien. P?dagogisierung l?sst sich zweitens als Ausdifferenzierung eines symbolisch-kommunikativen Systems innerhalb der Gesellschaft beschreiben. Diese Vorstellung referiert auf die Abl?sung des P?dagogischen von den klassischen Erziehungsinstitutionen. Vor dem Hintergrund dieser Unterscheidung rückt der vorliegende Beitrag in drei Fallstudien den gesellschaftlichen Umgang mit dem so genannten Dritte-Welt-Problem in der Bundesrepublik in das Blickfeld. Die dabei zu beobachtenden Bezugnahmen auf P?dagogik durch die Dritte-Welt-Protestbewegung, das zust?ndige Bundesministerium und Organisationen des Erziehungssystems werden als je unterschiedliche P?dagogisierungsf?lle rekonstruiert. Deren Hybridit?t, d.h. sowohl Eingrenzung wie Entgrenzung, sowohl Bezug des P?dagogischen auf wie auch Abl?sung des P?dagogischen vom institutionalisierten Erziehungssystem, legt es theoretisch nahe, so die These, P?dagogisierungsprozesse in den Zusammenhang von Formbildungen des P?dagogischen einzuordnen.     

The effect of practical work on students' understanding of combustion

This paper describes a study which investigated 14 and 15 year old students' understanding of combustion in both England and Spain, and explores the effect of practical laboratory experience on students' understanding. The teaching and learning styles used with the students in the study were explored using questionnaires and interviews. The students' understanding of combustion was explored using a questionnaire. The responses of English and Spanish students are significantly different. The quality of the responses is explored in terms of the awareness of students of the involvement of gases in combustion, and it appears, however, that the more extensive use of practical work in English schools has had only a marginal effect on their understanding of combustion.

Including students’ diverse perspectives on classroom interactions into video-based professional development for teachers

Video is often used in professional development courses to sensitize mathematics teachers to students’ thinking and issues of classroom interaction. This article presents an approach that incorporates students’ perspectives on mathematics classroom interactions into video-based professional development in order to enhance teachers’ reflection on diverse awareness of students concerning demands within mathematics classroom interactions. This approach is theoretically justified by the empirical research on equal participation in classroom interaction and practically elaborated by video material from Grade 5 students. Empirical snapshots from design experiments with teachers demonstrate that teachers’ sensitivity can be enhanced.

The impact of bilingual preschool education on the language development of Spanish-speaking children

This study addressed the question of what effect bilingual preschool education has on the Spanish and English language development of Spanish speaking children. This question was addressed by measuring the language proficiency of children enrolled in a bilingual preschool program and children who stay at home during the day. Three dimensions of language proficiency were examined: language reception, production, and verbal complexity. Using a repeated measures design, it was found that children enrolled in preschool gained proficiency in English at a faster rate while maintaining a similar level of Spanish proficiency as those children who stay at home during the day. Results of this study are discussed in terms of current issues in the early childhood education of non-English-speaking children.     

Student satisfaction in higher education: a meta-analytic study

This paper discusses the results of a meta-analysis performed to identify key antecedent and consequent constructs of satisfaction in higher education. We offer an integrated model to achieve a better understanding of satisfaction in the context of higher education. To accomplish this objective, we identified 83 studies that were valid and relevant to the research objective of the current study, generating a total of 469 observations. We identified studies published from 1986 to 2016 and analyzed six antecedent dimensions (perceived value of educational services, resources provided to the student, service quality perception, marketing orientation, identity of the higher education institution, university environment) and one consequent dimension related to satisfaction. The 7 dimensions exhibited a total of 51 relationships. We believe that the originality of the findings clearly contributes to future academic research in higher education.
