Students Fail to Transfer Knowledge of Chromosome Structure to Topics Pertaining to Cell Division

Cellular processes that rely on knowledge of molecular behavior are difficult for students to comprehend. For example, thorough understanding of meiosis requires students to integrate several complex concepts related to chromosome structure and function. Using a grounded theory approach, we have unified classroom observations, assessment data, and in-depth interviews under the theory of knowledge transfer to explain student difficulties with concepts related to chromosomal behavior. In this paper, we show that students typically understand basic chromosome structure but do not activate cognitive resources that would allow them to explain macromolecular phenomena (e.g., homologous pairing during meiosis). To improve understanding of topics related to genetic information flow, we suggest that instructors use pedagogies and activities that prime students for making connections between chromosome structure and cellular processes.     

“I didn’t know water could be so messy”: coteaching in elementary teacher education and the production of identity for a new teacher of science

Through the examination of the experiences of a pre-service teacher participating in a field-based science methods course, we make evident the ways in which a combination of collaborative teaching experiences and reflexive dialogues allowed for the evolution and transformation of her identity. This teacher is Johaira Lara, the second author of this paper, and we have engaged in a cowriting approach that has created layers of writings over time, with the focus of providing evidence of her changing perceptions and understandings of teaching and learning science. We describe the ways coteaching and cogenerative dialogues provided the opportunity for Johaira to examine and reconsider her views on science teaching, and mediated the production and transformation of her identity. We offer an evolving analysis of her identity transformation related to specific aspects of the course that were pivotal for her emergence as an elementary teacher of science.

Recent developments in technology have transformed the telephone from an exclusively interpersonal medium to an interactive electronic mass medium. The diffusion of innovations framework was applied to examine whether adoption of audiotext and 1–900 services is related to use of functionally similar entertainment media. Findings suggest that adoption of audio information services was more powerfully explained by media use patterns than demographics.     

Multidimensional Perfectionism,Depression, and Satisfaction With Life: Differences Among Perfectionists and Tests of a Stress‐Mediation Model

This study examined the relationship between adaptive and maladaptive perfectionism, stress, depression, and satisfaction with life in a sample of undergraduate women. The authors found that maladaptive perfectionists had lower satisfaction with life and higher stress and depression scores compared with adaptive perfectionists. Results also indicated that stress mediated the relationship between maladaptive perfectionism and depression and between both maladaptive and adaptive perfectionism and satisfaction with life. Implications for college counselors are discussed.     

Alltagssituationen und Experimente: Was sind geeignete naturwissenschaftliche Lerngelegenheiten für Kindergartenkinder?

Natural sciences are an educational topic in kindergartens. At the same time, little is known about how to promote and facilitate the learning of natural sciences for children in kindergarten. This contribution reports on a quasi-experimental study with 245 children, which compares the learning situations ‘experiments’ with ‘discussions on the relevance of the natural sciences in daily life’. Three experimental groups, in which the learning situations were varied, where compared with a control and a baseline group. Children in the last year of kindergarten took part in three 90-minute learning settings on the topics ‘melting and freezing water’, ‘evaporation and condensation of water’ and ‘solubility and insolubility in water’. Learning gains were measured using a pre-post-design with a Rasch-scaling. Cognitive performance and family background were controlled for. A significant benefit in comparison to the control and baseline groups could only be found for a combination of both learning situations.     

Reading between the lines: Implicit assessment of the association of parental attributions and empathy with abuse risk

ObjectiveResearchers in the child maltreatment field have traditionally relied on explicit self-reports to study factors that may exacerbate physical child abuse risk. The current investigation evaluated an implicit analog task utilizing eye tracking technology to assess both parental attributions of child misbehavior and empathy.MethodBased on the observation that readers experience comprehension difficulty when encountering passages inconsistent with their beliefs, an eye tracker gauged the extent of difficulty parents experienced reading vignettes that inappropriately characterized a child as culpable for misbehavior and that presented a non-empathic child interaction.ResultsResults suggest self-reports of attributions and empathy are related to both child abuse potential and discipline intentions; however, the eye tracking analog for empathy correlated with abuse potential but not punishment decisions whereas the analog for attributions correlated with punishment decisions but not abuse potential.ConclusionsSuch contrasts between self-report and analog assessment underscore the need for continued research studying theorized abuse risk constructs using alternative approaches to better identify the important risk markers associated with elevated child abuse risk and to minimize methodological overlap.     

Students’ Experience of Working with Socioscientific Issues - a Quantitative Study in Secondary School

This research project aims to investigate how students in lower secondary school experience work with socioscientific issues (SSI). The six socioscientific cases developed and used in this project are relevant according to characteristics of SSI and to the national curriculum. Approximately 1,500 students in Sweden have worked with one SSI case chosen by the teachers. A questionnaire-based instrument was used to measure the affective domain of students?? attitudes towards and interest in science before starting to work with the case and a second questionnaire after finishing a case. The second student questionnaire, measured the situational characteristics of the SSI work and perceived cognitive and affective outcomes. According to the students?? self-reported experience, all cases were interesting and related to a current issue. Most cases were equally interesting to boys and girls, the only exception was You are what you eat, which girls found more interesting than boys did. Almost all students claim that they learnt new facts, learnt to argue for their standpoint and to search and evaluate information during the work with the cases. The girls?? average scores were higher on several aspects of learning outcomes. Furthermore the students, especially the girls, perceived that the outcome of working with SSI had relevance for their future, with some cases more relevant than others. The more interesting the student found the case, the more they claimed they learnt. The students do not, however, claim that they learnt more science than during ordinary lessons.     

Developing a research partnership: teachers as researchers and teacher educators

This paper discusses a combined university–school research project involving three associate teachers from the pre-service teacher education degree at the University of Otago, New Zealand in the examination of their literacy teaching practice. The provision of resources for this collaborative study allowed the teachers to design the project in response to the learning needs of the children in their classrooms. The paper specifically analyses the research experience for the teachers as they theorized their classroom literacy practice and utilized the research findings to inform the content and processes of teaching at both the primary and tertiary classroom levels.     

An examination of the conflict resolution strategies and goals of children with depressive symptoms

The purpose of this study was to examine (a) the reports of conflict strategies and goals in response to hypothetical conflict situations, (b) generation of solutions to hypothetical conflicts, and (c) conflict in observed dyadic exchanges in children with high and low depressive symptoms. Children from Grades 4, 5, and 6 were divided into high (n = 57) and low (n = 57) depressive symptoms groups. Results indicated that the two groups differed on the types of conflict strategies but not conflict goals chosen in hypothetical social problem‐solving tasks. Also, children reporting depressive symptoms typically chose less effective strategies to solving social problems. In observed dyadic exchanges, the high depressive symptoms group employed more negative strategies than the low depressive symptoms group, but no significant differences were noted for the prosocial conflict resolution strategies exhibited. Findings and implications for children with depressive symptoms are highlighted.     

Understanding students' interactions: why varied social tasks matter

Many social interactions between school‐age children contain both competitive and cooperative elements. In order to gain a better understanding of how students at risk for emotional and behavioural difficulties (EBD) negotiate social exchanges in cooperative and competitive‐related tasks in comparison with non‐EBD students: (a) prosocial; (b) negative; and (c) conflict behaviours were assessed. Fifty‐seven children at risk for EBD and 57 comparison children participated in three different social tasks with non‐target partners. Both students and teachers completed a standardised behaviour checklist. Social ability and sex differences were considered. Results are discussed from a social‐cognitive framework, and practical implications will be highlighted.
