One Cow Does Not an Animal Make: Young Children Can Extend Novel Words at the Superordinate Level

Six match-to-sample picture/object selection experiments were designed to explore children's knowledge about superordinate words (e.g., "food") and how they acquire this knowledge. Three factors were found to influence the learning and extension of superordinate words in 3- to 5-year-old children (N = 230): The number of standards (one versus two), the type of standards presented (from different basic-level categories versus from the same basic-level category), and the nature of the object representations used (pictures versus objects). A different pattern of superordinate word acquisition was found between 3-year-olds and 4- and 5-year-olds. Although 4- and 5-year-olds could learn and extend novel words to superordinate categories in the presence of two picture exemplars from different categories or a single three-dimensional (3-D) exemplar, 3-year-olds could do so only in the presence of two 3-D exemplars. These findings indicate that young children's acquisition of superordinate words is influenced by multiple factors and that there is a developmental progression from multiple exemplars to single exemplars in superordinate word learning.     

Does a Nexus Exist Between the Work of Administrators and Student Outcomes in Higher Education?: An Answer from a Systematic Review of Research

Journal articles within the field of higher education that focus on college and university administrators, have for the most part, examined topics such as leadership, governance, and institutional effectiveness. Recently, internal and external critics have questioned the ability of college and universities to impact educational outcomes, more specifically student outcomes. In this regard, this study sought to examine how the work of administrators in higher education affects student outcomes. From a systematic review of 10 years of research studies on higher education that focus on administrators as a unit of analysis in higher education, the researchers found that the nexus between the work of administrators and student outcomes was nascent.     

Population education in the USA

By the late 1960s, universities and private organizations began to develop population education programs and courses in the wake of the warning of demographer Philip M. Hauser about the lack of demographic information in the school curriculum. In the early 1970s, the US Department of Health, Education, and Welfare provided limited funding for teacher training workshops and classroom materials. Baltimore City's district wide population education program proved successful in 1975 after 10 years of work, population education materials were adopted in the official social studies curriculum, and this model was accepted later by other school systems. In 1979 not quite 15 US colleges and universities taught population issues at graduate-level training or by offering workshops and materials. By the mid-1970s, universities and private organizations were conducting conferences and workshops for secondary school teachers. In the 1970s, these included the Center for Information on America. Environment-Population Education Services, Planned Parenthood, Population Institute, Population Reference Bureau (PRB), the World Bank, and Zero Population Growth (ZPG). In the 1970s and early 1980s various other organizations contributed to population educations, e.g. the University of Cincinnati by organizing institutes, the National Catholic Educational Association representing 8200 schools ZPG with teacher-training workshops, and PRB with meaningful materials for students and teachers. The state of population education in 1992 means that PRB staff lead 15-30 workshops each year and provide workshop materials for teachers. ZPG emphasizes hands-on learning. Pet Net, a network of volunteer teacher trainers leading workshops, and ZPG staff conducted 88 workshops in 1991.     

Engagement in Academic Work: The Role of Learning Goals, Future Consequences, Pleasing Others, and Perceived Ability

Engagement in academic work was viewed from a multiple goals perspective. Two studies were conducted in which high school math students completed an instrument measuring five goals students might have for doing academic work (learning goals, performance goals, obtaining future consequences, pleasing the teacher, and pleasing the family), perceived math ability, self-regulatory activities, strategies (deep or shallow) used when studying for math, and the amount of effort and persistence expended on the class. Factor analysis indicated that the five goals scales and the perceived ability scale represented unique factors. The correlations among the variables revealed theoretically consistent interrelationships. Multiple regression analyses indicated that various goals (e.g., learning goals, obtaining future consequences, and pleasing the teacher), perceived ability, and some interactions accounted for significant amounts of variance in the task engagement measures (self-regulation, strategy use, effort, and persistence) and achievement. Results are discussed in relation to current theory and their practical implications.     

Individual and group meaning‐making in an urban third grade classroom: Red fog,cold cans,and seeping vapor

We examined third graders' understandings of condensation using an expanded notion of the Emergent Perspective, a reflexive consideration of individual and group meaning‐making situated in the culture of the classroom. Data were collected from two small groups of students in an inquiry‐based, urban classroom during a unit on the water cycle. Measures included conceptual pre‐/posttests, interviews, written work, and discourse analyses of a science lesson. Although we identified the supportive role of the teacher's explicit assessments of children's ideas, within the small groups, the force that most potently shaped meaning‐making was students' persuasive power, which was in part influenced by the rhetorical moves employed. Specifically, students' evaluative comments (a type of rhetorical move) about contributions of other group members seemed to be particularly persuasive in these groups. Evaluative comments, apart from students' academic status, were shown to be an important influence in not only social knowledge production but also in individual internalization. Our explanation focuses on the particular discursive practices as intellectual resources of urban students, but we are also mindful of the cognitive complexity of the material and the developmental abilities of the students. © 2005 Wiley Periodicals, Inc.

Early career teachers’ emotion and emerging teacher identities

The goal of our project was to develop an understanding of the connections among emotional episodes and emerging professional teacher identities of first year teachers. We interviewed eight first year mathematics and science teachers. We asked them to reflect on emotional episodes and talk about how those emotions informed their teaching identities. Our data yielded a model of ‘identity-work’ that reflected the teachers’ engagement in a reflective process of understanding themselves as it related to those emotional episodes. Our model includes four key processes: (1) Teacher incoming identity beliefs; (2) Teacher identity emotional episodes; (3) Teacher attributions and (4)Identity adjustment. All of our teachers exhibited a form of this process with some teachers elaborating on the ways in which pleasant emotional experiences confirmed their identities and others elaborating on the ways in which unpleasant emotional experiences caused them to confront and/or adjust their emergent identities. Implications for future research and teacher education are discussed.

Tracking of the expected time to reinforcement in temporal conditioning procedures

In one experiment, the rate and pattern of responding (head entry into the food cup) under different distributions of intervals between food deliveries were examined. Separate groups of rats received fixed-time (45, 90, 180, or 360 sec), random-time (45, 90, 180, or 360 sec), or tandem fixed-time (45 or 90 sec) random-time (45 or 90 sec) schedules of reinforcement. Schedule type affected the pattern of responding as a function of time, whereas mean interval duration affected the mean rate of responding. Responses occurred in bouts with characteristics that were invariant across conditions. Packet theory, which assumes that the momentary probability of bout occurrence is negatively related to the conditional expected time remaining until the next reinforcer, accurately predicted global and local measures of responding. The success of the model advances the prediction of multiple measures of responding across different types of time-based schedules.     

Healthy Families New York (HFNY) randomized trial: effects on early child abuse and neglect

OBJECTIVE: To evaluate the effects of a home visiting program modeled after Healthy Families America on parenting behaviors in the first 2 years of life. METHODS: A sample of 1173 families at risk for child abuse and neglect who met the criteria for Healthy Families New York (HFNY) was randomly assigned to either an intervention group that was offered HFNY or a control group that was given information and referrals to other services. Data were collected through a review of CPS records, and maternal interviews at baseline and the child's first birthday (90% re-interviewed) and second birthday (85% re-interviewed). RESULTS: HFNY mothers reported committing one-quarter as many acts of serious abuse at age 2 as control mothers (.01 versus .04, p<.05). Two sets of interactions were tested and found to have significant effects (p<.05). At age 2, young, first-time mothers in the HFNY group who were randomly assigned at 30 weeks of pregnancy or less were less likely than counterparts in the control group to engage in minor physical aggression in the past year (51% versus 70%) and harsh parenting in the past week (41% versus 62%). Among women who were "psychologically vulnerable," HFNY mothers were one-quarter as likely to report engaging in serious abuse and neglect as control mothers (5% versus 19%) at age 2. CONCLUSIONS: These findings suggest that who is offered home visitation may be an important factor in explaining the differential effectiveness of home visitation programs. Improved effects may be realized by prioritizing the populations served or by enhancing the model to meet program objectives for hard-to-serve families.     

Experiences of HIV/AIDS Counselors in Zimbabwe and Their Perceptions on the State of HIV/AIDS Counseling in Zimbabwe

This study investigated Zimbabwean counselors' experiences of providing HIV/AIDS counseling and their perceptions about the state of HIV/AIDS counseling in Zimbabwe. The participants were a diverse group of counselors, 30 through 59 years of age, who provided counseling services to HIV/AIDS clients. Participants thought HIV/AIDS counselors in Zimbabwe received minimal support and supervision and were undertrained. They identified that the first sessions with clients were the most difficult. They also found it problematic to work with couples who were serodiscordant (one partner who is HIV positive and the other HIV negative) and couples wanting children. The later stages of the counseling process were also found to be challenging. Though the participants acknowledged they had negative psychological experiences when counseling HIV/AIDS clients, they also expressed feelings of satisfaction and fulfillment in their work.
