Identification with early primary school mathematics: a home–school activity theory conceptualisation and methodology

This paper offers a new methodology for researching children’s identifications in the early primary phase that makes visible the ‘seeds’ of academic dis-/identities, which typically flower later in adolescence. It focuses on the ‘case’ of mathematical identifications (MI) to exemplify how children come to dis/identify from the academic curriculum more broadly. MI is defined as any act where cultural representations of being mathematical are reflected back on to the child by others or the self, as they engage in mathematical activity. Data are presented concerning Bilal and Nico to show identifications in a hybrid home–school mathematics activity that contradict or ‘align’ with MI elicited in school-mathematical activity. It is argued that contradictions between these MIs indicate ‘potential’ development towards disengagement (the case of Nico). This contrasts with home–school alignment involving Bilal’s ‘schoolified’ home activities, which (re)validate school-mathematical activity. It is further argued that this conceptual innovation offers potential for investigating identity in early childhood.     

Causal modeling of secondary science students' intentions to enroll in physics

The purpose of this study was to explore the utility of the theory of planned behavior model developed by social psychologists for understanding and predicting the behavioral intentions of secondary science students regarding enrolling in physics. In particular, the study used a three-stage causal model to investigate the links from external variables to behavioral, normative, and control beliefs; from beliefs to attitudes, subjective norm, and perceived behavioral control; and from attitudes, subjective norm, and perceived behavioral control to behavioral intentions. The causal modeling method was employed to verify the underlying causes of secondary science students' interest in enrolling physics as predicted in the theory of planned behavior. Data were collected from secondary science students (N = 264) residing in a central Texas city who were enrolled in earth science (8th grade), biology (9th grade), physical science (10th grade), or chemistry (11th grade) courses. Cause-and-effect relationships were analyzed using path analysis to test the direct effects of model variables specified in the theory of planned behavior. Results of this study indicated that students' intention to enroll in a high school physics course was determined by their attitude toward enrollment and their degree of perceived behavioral control. Attitude, subjective norm, and perceived behavioral control were, in turn, formed as a result of specific beliefs that students held about enrolling in physics. Grade level and career goals were found to be instrumental in shaping students' attitude. Immediate family members were identified as major referents in the social support system for enrolling in physics. Course and extracurricular conflicts and the fear of failure were shown to be the primary beliefs obstructing students' perception of control over physics enrollment. Specific recommendations are offered to researchers and practitioners for strengthening secondary school students' intentions to study physics.     

A conceptual framework for job change

Change related to the job is identified as an exigent issue in the field of career development. This paper presents an effort to conceptualize a job change framework. The intent is increase awareness, generate discussion, and stimulate empirical research in this area.The conceptual framework for job change has been predicated on client concerns. The framework involves the unique relationship of several life factors which influence individual job change, and provides a means for systematic personal decision-making. A schematic diagram is also included as a tool that can be used for counseling and research applications.     

Experience and brain development

This article considers how experience can influence the developing and mature brain and proposes a new categorization scheme based upon the type of information stored and the brain mechanisms that appear to be involved in storing it. In this scheme, experience-expectant information storage refers to incorporation of environmental information that is ubiquitous in the environment and common to all species members, such as the basic elements of pattern perception. Experience-expectant processes appear to have evolved as a neural preparation for incorporating specific information: in many sensory systems, synaptic connections between nerve cells are overproduced, and a subsequent selection process occurs in which aspects of sensory experience determine the pattern of connections that remains. Experience-dependent information storage refers to incorporation of environmental information that is idiosyncratic, or unique to the individual, such as learning about one's specific physical environment or vocabulary. The neural basis of experience-dependent processes appears to involve active formation of new synaptic connections in response to the events providing the information to be stored. Although these processes probably do not occur entirely independently of one another in development, the categories offer a new view more in accord with neural mechanisms than were terms like "critical" or "sensitive period."     

Using the standard Wald confidence interval for a population proportion hypothesis test is a common mistake

Employing a Wald confidence interval to test hypotheses about population proportions could lead to an increase in Type I or Type II errors unless the hypothesized value, p0, is used in computing its standard error rather than the sample proportion.

Ethos,Habitus and Situation for Learning: An ecology

It is argued that the concept of ethos connects with Bourdieu's 'habitus' and the notion of situated learning. It can be argued that ethos can be defined as an organisation's habitus. An ecological perspective suggests that habituses external to the school provide dispositions that continuously construct and re-construct school ethos, and the evolving ethos itself provides developing dispositions and contexts for situated co-learning and participation in communities of practice; for example, shared learning about how to learn. Some implications for school improvement and leadership in schools are discussed.     

The economic impact of nonresident students on West Virginia's economy

This paper describes a cost-benefit analysis of the impact of nonresident higher education students on the economy of West Virginia during the academic year 1985–86. During that year, the 10,091 FTE nonresident students enrolled in higher education institutions in West Virginia contributed to the state economy an estimated $72,182,000 through tuition and fees, living expenses, and travel expenses of parents and friends. The $72,182,000 flowing through the state's economy generated $86,618,318 in direct and indirect financial benefit to the state, while the state allocation attributed to the education of these nonresident students was $28,668,537. This return on investment, a benefit to cost ratio of 3.02, represents the net economic impact on West Virginia's state and local economies associated with higher education's nonresident enrollment in 1985–86. The ratio suggests that for each one dollar invested by the state in non-resident students, the state realized a return of $3.02 over the period of one academic year.Presented at the Twenty-Seventh Annual Forum of the Association for Institutional Research, Kansas City, May 1987.     

Polynesian Folklore: An Alternative to Plastic Toys

Because folklore has the capability to teach and to preserve the thoughts, feelings, and beliefs of a people, suggestions are offered for using folklore to deepen children's understanding of Polynesian culture. Maori nature fables, along with error/punishment stories involving the woman or man on the moon, represent the instructive function. Tales and legends preserving cultural history are represented by a folk story reflecting values and customs of everyday life, accounts of legendary monsters reflecting cultural hopes and fears, and heroic tales of the popular demigod Maui. Specific stories are reviewed, juvenile collections are referenced, and classroom activities are offered.     

Enumeration of lymphocyte subsets using flow cytometry: Effect of storage before and after staining in a developing country setting

Lymphocyte subset estimations by flow cytometry in population-based studies require transportation of samples from the field site to the laboratory. As samples arrive late in the day they have to wait overnight before being processed. The effect of two possible approaches, sample storage for 24 h before staining and immediate staining with analysis after 24 h and 48 h were evaluated. Two sets of experiments were performed with EDTA (ethylenediamine tetra-acetate) anticoagulated peripheral blood. In the first experiment, after collection, each sample was divided into two portions. One portion was stained at the time of blood collection and the other 24 h later after keeping it at room temperature (38–45°C). In the second experiment, blood samples were stained within 1–2 h. Each sample was analyzed immediately upon completion of staining process and subsequently after 24 h and 48 h of storage at 4°C. Results suggest that blood collected in EDTA can be processed using whole blood lysis method, after storage at room temperature (38–45°C) for 24 h with some but not significant alteration in T-cell subsets. Storage at 4°C after staining for 24 h results in a lesser and insignificant loss of cells or alteration of T-cell subsets and may be the method of choice.
