A Longitudinal Study Showing how Students use a Molecule Concept when Explaining Everyday Situations

In this paper we present results from a 10‐year (1997–2006) longitudinal study in which we, by interviews once or twice every year, followed how students, throughout the compulsory school, developed their understanding of three situations in which transformations of matter occur. We believe that students have to meet scientific ideas early in order to gradually, in social cooperation with classmates, friends, teachers, and other grown‐ups, elaborate the meaning of a concept. We followed 23 students all born in 1990. In 1997 we introduced the idea of the particulate nature of matter. We have conducted interviews allowing students to explain the transformation of matter in fading leaves left lying on the ground, burning candles, and a glass of water with a lid on. In the interview at 16 years of age, less than one‐fifth of the students use molecular ideas in scientifically acceptable ways. The overall conclusion is that most students do not connect the knowledge they gain in school about the particulate nature of matter to these everyday situations. On the other hand, the students seem capable of using a simple particle model and the model can help them understand the invisible gas state. The question of how to use this capability in order to develop students’ scientific ideas is still not solved and more research is argued for.     

Developing narratives as a pedagogical approach to fostering professional interpersonal competences

The study examined a project aimed at helping students develop professional interpersonal skills. Groups of university students in social work, teacher training, and a student mentoring program for children at-risk participated in seminars where they developed narratives derived from personal experience in interaction with others. The theoretical framework for the project was inspired by the idea of “stories to live by” developed by Clandinin and Connelly. Data for the study were collected from questionnaires, interviews, and focus groups. Results indicated that narrative-building activities, when implemented in a structured and consistent manner, can contribute to improving empathy and perspective-taking abilities, developing self-knowledge, and enhancing communication skills.     

Different Methods – Different Results: How the Swedish Results in Mathematics Vary Depending on Methodological Approach

The results for TIMSS population 2 in Sweden indicated that Swedish student achievement in mathematics was average. There were even mass media reports that indicated that Swedish students had some of the lowest results in mathematics. The issue that is addressed in this article is whether the performance of Swedish students is average or even low. To answer this, the basis of comparison between the different countries needs to be discussed. Mass media, for example, based its comparison on all 45 countries participating in TIMSS population 2 and in its national TIMSS report, the Swedish National Agency for Education presented a different selection of countries. The report compared the results of the 25 countries that met the sampling requirements set by the TIMSS International Study Centre. This focuses the discussion on what approaches are used when comparing results from different countries in an international comparative study. In this article the TIMSS results, as presented by the Swedish National Agency for Education, are compared with the results obtained with other methodological approaches. The comparison is based on the importance of three variables for the results of the comparison: equal number of years in school, the selection of countries, and the contents of the textbooks in the different countries. The results indicate that the number of years in school, as well as the content of the textbooks in each country, are important factors when comparing the results for different countries.     

Remembering Nina Lenček, 18 January 1924–25 November 2014

Columbia University Libraries’ longtime Slavic & East European Studies Librarian Nina Len?ek passed away on November 25, 2014, at the age of 90. On January 22, 2015, a large group of her friends, family, and colleagues gathered at Butler Library to remember, honor, and celebrate her remarkable life and legacy.     

A Conceptual Characterization of Online Videos Explaining Natural Selection

Educational videos on the Internet comprise a vast and highly diverse source of information. Online search engines facilitate access to numerous videos claiming to explain natural selection, but little is known about the degree to which the video content match key evolutionary content identified as important in evolution education research. In this study, we therefore analyzed the content of 60 videos accessed through the Internet, using a criteria catalog with 38 operationalized variables derived from research literature. The variables were sorted into four categories: (a) key concepts (e.g. limited resources and inherited variation), (b) threshold concepts (abstract concepts with a transforming and integrative function), (c) misconceptions (e.g. that evolution is driven by need), and (d) organismal context (e.g. animal or plant). The results indicate that some concepts are frequently communicated, and certain taxa are commonly used to illustrate concepts, while others are seldom included. In addition, evolutionary phenomena at small temporal and spatial scales, such as subcellular processes, are rarely covered. Rather, the focus is on population-level events over time scales spanning years or longer. This is consistent with an observed lack of explanations regarding how randomly occurring mutations provide the basis for variation (and thus natural selection). The findings imply, among other things, that some components of natural selection warrant far more attention in biology teaching and science education research.     

Influences of family based prerequisites,reading attitude,and self-regulation on reading ability

This study investigated the effect of self-regulated learning, as indicated by academic self-concept, motivation and learning strategies, reading attitude and family based prerequisites on reading ability. Students (n = 4018) in the eighth grade answered the IEA reading literacy test, the self-regulated learning questionnaire and a student questionnaire about their background. The exploratory factor analysis (EFA) revealed that the self-regulated learning questionnaire did not measure the intended three dimensions, but only two: Verbal/General academic self-concept and a new dimension called Goal oriented strategies. Structural Equation Modelling (SEM) with a cross-validation sample was conducted to determine the effects in the final model. The strongest effect on reading ability was from Verbal/General academic self-concept (β = .43 for final and β = .56 for cross-validation model). Gender differences revealed that girls read better on narrative and expository texts, had a more positive reading attitude, and more positive verbal self-concept, whereas boys had a higher academic self-concept (not domain-specific), self-efficacy, control expectation, reported more memorising, elaboration, and instrumental motivation (all differences p < .001).     

Brauchen mehrsprachige Jugendliche eine andere fach- und sprachintegrierte Förderung als einsprachige?

Which kinds of content- and language-integrated interventions can better support mathematical learning, depending on students’ language background, as measured by communication on the discourse level or additional lexical training on the word level? A control trial compared interventions with two different materials (discursive versus lexical-discursive, each 5 × 90?min.) with respect to the dependent variable of conceptual and procedural knowledge for fractions. The effects are investigated differentially for four language groups: monolinguals versus bilinguals, each with higher versus lower German language proficiency (n = 343). For both interventions, the ANOVA shows an increase of mathematical knowledge for the experimental group, which is significantly higher than for the control group, but no significant difference between the interventions. The intervention with lexical-discursive materials led to a slightly higher increase of knowledge in the post test, but the discursive intervention was superior in the follow up test. Monolingual and multilingual students had similar patterns of growth without differential pattern. However, the proficient monolingual students tend to profit more from the interventions, especially from the lexical-discursive intervention.     

The power of positioning: on the normalisation of gender,race/ethnicity,nation and class positions in a Swedish social work textbook

This article presents a feminist reading of a Swedish social work academic textbook as a case study. We use a discourse analytic approach and positioning theory, focusing on author positions through different story lines. The aim is to make visible how differences are created and positions of the author/reader normalised in terms of gender, race/ethnicity and class. The analysis illustrates how the organisation of the book privileges a particular story line by presenting gender research in a special section of the book and as a perspective. A neutral, unmarked author position is assumed, presented as a common ‘we’ by identifying ‘women researchers’ and ‘feminist’ points of departure as different. If the unmarked author/reader ‘we’ position appears desirable and morally superior, the clients’ gender, ethnicity and class are often openly discussed in relation to social problems, positioning them as ‘the other’. Finally there is also a story line of more critical and ambivalent knowledge positions.
