Metacognitive and multimedia support of experiments in inquiry learning for science teacher preparation

ABSTRACT

Promoting preservice science teachers’ experimentation competency is required to provide a basis for meaningful learning through experiments in schools. However, preservice teachers show difficulties when experimenting. Previous research revealed that cognitive scaffolding promotes experimentation competency by structuring the learning process, while metacognitive and multimedia support enhance reflection. However, these support measures have not yet been tested in combination. Therefore, we decided to use cognitive scaffolding to support students’ experimental achievements and supplement it by metacognitive and multimedia scaffolds in the experimental groups. Our research question is to what extent supplementing cognitive support by metacognitive and multimedia scaffolding further promotes experimentation competency. The intervention has been applied in a two-factorial design to a two-month experimental course for 63 biology teacher students in their first bachelor year. Pre-post-test measured experimentation competency in a performance assessment. Preservice teachers worked in groups of four. Therefore, measurement took place at group level (N?=?16). Independent observers rated preservice teachers’ group performance qualitatively on a theory-based system of categories. Afterwards, experimentation competency levels led to quantitative frequency analysis. The results reveal differing gains in experimentation competency but contrary to our hypotheses. Implications of combining scaffolding measures on promoting experimentation competency are discussed.     

REPORT ON FIVE CITIES

This article examines one university's policies regarding Native mascots and ethnic fraud through a Tribal Critical Race Theory analytic lens. Using the principle of interest convergence, we argue that institutions of higher education allow and even work actively towards a particular form or level of diversity, but they do not extend it far enough. Once racial remedies no longer hold value or benefit the institution itself, the status quo is maintained. Ultimately, the university has an interest in “celebrating” diversity and supporting superficial multiculturalism, but it does not have an interest in critical, social justice-oriented policies that challenge the status quo, the current racial order, or the institution's privilege and power.

Changers and the Changed: Moral Aspects of Coming Out in Physical Education

In this paper we draw from interviews with four lesbian sportswomen and physical educators whose personal journeys inform us about the difficulties and rewards of challenging homophobia and heterosexism. Our co-participants discussed their life stories in terms of the interrelationships among sport, moral, and lesbian identities and their coming out process. Analyses of these narrations revealed three major themes associated with coming out in sport and physical education settings: integrity, compassion, and community. Each of these themes is discussed in terms of our co-participants' experiences and interpretations of moving from fear and isolation to a sense of community and empowerment.     

School choice in England: evidence from national administrative data

We study school choice in England using a new dataset containing the choices of all parents seeking a school place in state secondary schools. We provide new empirical evidence to inform how the school choice market functions, including the number of choices made, whether the nearest school is the first choice and the probability of an offer from the first choice school. These indicators show that school choice is actively used by many households in England. We use the rich data available to describe how choices vary by pupil, school and neighbourhood characteristics and how school choice is used differently by different groups and in different parts of the country. For the first time, we are able to present national data on how the school choices made by parents vary according to pupils’ ethnic group and across urban and rural areas. We show, contrary to some existing literature that has relied on smaller and less representative samples of parents and pupils, that school choices do not vary significantly by social background. We show that parents pro-actively use the choice system and present new evidence on the extent to which the current school admissions criteria that prioritise distance penalise poorer families.     

Promoting secondary school students’ evaluation of source features of multiple documents

The current research examined whether instructional activities centering on contrasting cases promoted secondary school students’ evaluations of source features present in a multiple-documents inquiry context. Two hypothetical students’ document evaluation strategy protocols were designed: One featured more sophisticated strategies commonly enacted by experts and better college students and a second featured less sophisticated strategies commonly enacted by secondary school students. A series of classroom-based activities required that students compare/contrast the two protocols to decide which were the best strategies when analyzing multiple scientific documents and why. The findings demonstrated that students who previously participated in the intervention activities included more scientific concepts from more useful documents when generating essay responses from memory, displayed better rankings of the usefulness of the set of multiple documents, and offered more principled justifications based on source feature evaluations of trustworthiness compared to students who instead received typical classroom instruction. We discuss the instructional implications of a contrasting-cases approach in facilitating secondary school students’ usage of source features within multiple-documents inquiry contexts.     

The cognitive development of young dual language learners: A critical review

Dual language exposure and bilingualism are relatively common experiences for children. The present review set out to synthesize the existing research on cognitive development in bilingual children and to identify the gaps and the methodological concerns present in the existing research. A search of major databases for research conducted with typically developing, preschool-age dual language learners between 2000 and 2013 yielded 102 peer-reviewed articles. The existing evidence points to areas of cognitive development in bilingual children where findings are robust or inconclusive, and reveals variables that influence performance. The present review also identifies areas for future research and methodological limitations.
