The Role of Semantic Context and Memory in the Acquisition of Novel Nouns

Three studies assessed the ability of 2-year-olds to use semantic context to infer the meanings of novel nouns and to retain those meanings a day later. In the first experiment, 24 2-year-olds heard novel nouns in sentences that contained semantically constraining verbs (e.g., "Mommy feeds the ferret"). They chose from a set of four novel object pictures to indicate the referent. Children learned a majority of the novel words. However, they occasionally failed to choose the correct object even when they understood the verb. Experiment 2 examined whether this was due to an inability to identify some of the pictures of novel objects. Experiment 3 tested 24 2-year-olds' memory for the newly learned nouns following a 24 hr delay and found significant retention. Results are discussed in terms of learning mechanisms that facilitate vocabulary acquisition in young children.     

Marriage and the Parenting Alliance: Longitudinal Prediction of Change in Parenting Perceptions and Behaviors

The study evaluates how marriage and the parenting alliance affect parenting experiences over time. Couples ( N = 79) with school-age children who have mental retardation completed self-report and observational measures of marriage, the parenting alliance, and parenting attitudes and behaviors at 2 periods, 18–24 months apart. Longitudinal structural equation modeling demonstrated significant effects of marital quality on changes over time in self-reports of perceived parenting competence for both the mothers and the fathers, and in observed negative mother-child interactions. Also, in all cases, the parenting alliance mediated the effects of marriage on parenting experiences. There was little evidence of reciprocal causation in which parenting variables predicted change in the quality of marriage and the parenting alliance. Interactions involving child age suggested that teenagers as opposed to younger children were more reactive to negative features of their parents' marital functioning and parenting alliance. Implications are discussed regarding stable but negative marital functioning and regarding possible differences in mothers' and fathers' parenting in the context of marital distress.     

Methodological considerations for studying science-in-the-making in educational settings

In this paper we explore the methodological implications of sociocultural approaches for the study of scientific knowledge and practices. Research in science studies and science education is reviewed with a focus on methodological considerations. Informed by empirically-based studies of scientific practices from multiple disciplinary perspectives, we describe our perspective for investigating science education which combines ethnography and discourse analysis. This theoretical position on the discursive nature of the social construction of school science-in-the-making forms the basis for theoretical and methodological critique and discussion. We provide a review of the history of nature of science (NOS) research to trace the methodological influence of Science and Technology Studies in science education. Four methodological issues associated with studying science as cultural practices are discussed: the local and contingent nature of situated definitions of science; theory dependence and coherence of research methodologies; attention to the study of school science-in-the-making; and reflexivity.     

Relationship of College Students' Current Attachment to Appraisals of Parental Conflict

This study assessed the relationship of parental attachment and gender to appraisals of conflict with parents in an effort to clarify the psychological mechanisms that mediate the relationship between attachment and psychological well-being. Appraisals of conflict with parents were found to be related to level of attachment and gender.     

Teaching in the 21 century

One of the hottest topics in higher education today is distance or distributed education (DE)—whether to get into it or not, whether it's as good as traditional in-class education or not, what forms of DE are better than others, whether it's a threat to faculty or not, and more. This paper addresses making sure DE efforts meet the course objectives and the students needs by working through five DE components: defining the students, defining the faculty, defining the curriculum, describing needed support systems, and understanding the environment created (ethical, aesthetic, cultural, and hidden aspects). Careful consideration of these five components will help ensure a successful DE program with positive experiences for faculty and students alike, and assure you readiness to embrace teaching in the 21^st century.     

Working memory for color in honeybees

Honeybees were tested in delayed conditional discrimination procedures (matching-to-sample and nonmatching-to-sample), using color stimuli presented on a video monitor. A small but reliable tendency to choose the color presented as the conditional cue was found, regardless of whether the contingencies reinforced or discouraged this tendency. The perseverative tendency occurred even with a delay of up to 1–2 min between the conditional cue and the choice. The tendency cannot be explained by changes in the associative value of the colors. Explanation of the results requires some form of working memory for color.     

Early Language Experience in a Tseltal Mayan Village

Daylong at-home audio recordings from 10 Tseltal Mayan children (0;2–3;0; Southern Mexico) were analyzed for how often children engaged in verbal interaction with others and whether their speech environment changed with age, time of day, household size, and number of speakers present. Children were infrequently directly spoken to, with most directed speech coming from adults, and no increase with age. Most directed speech came in the mornings, and interactional peaks contained nearly four times the baseline rate of directed speech. Coarse indicators of children’s language development (babbling, first words, first word combinations) suggest that Tseltal children manage to extract the linguistic information they need despite minimal directed speech. Multiple proposals for how they might do so are discussed.     

The role of research ethics committees: Friend or foe in educational research? An exploratory study

Ethics committees have an important role to play in ensuring ethical standards (e.g. BERA, ESRC, RCUK recommendations) are met by educational researchers. Balancing obligations to participants, society, institutions and the researchers themselves is not, however, easy. Researchers often experience the ethics committee as unsympathetic to their research endeavour, whilst ethics committees find some research approaches do not make ethical implications sufficiently explicit. This potential for misunderstanding is evident in the literature, but studies investigating how participants perceive this relationship are missing. This research comprises a novel empirical study which explores researcher perceptions of research ethics committees. Fifty-five participants in higher education departments of education responded to an online survey. Open and closed-ended questions were used to collect data on roles, methodological stance, experiences of the research ethics committee, perceived tensions and examples of good practice. The results indicated that contemporary educational researchers regard research ethics committees as friends when researcher and reviewer are transparently engaged in a shared endeavour. When this shared endeavour breaks down, for a variety of reasons—including apparently unreasonable demands or mutual misunderstanding—the research ethics committees can become foes. The difference between foe and friend lies in the quality of communication, clear systems and a culture of respectful mutual learning. The contributions of this study have practical implications for the ways that education researchers and research ethics committees relate to one another within university settings, both to alleviate areas of tension and to arrive at a shared understanding which will enable best ethical research practice.
