Whole-School Collaborative Sustained Professional Development and Science Teacher Change: Signs of Progress

The experiences of middle school science teachers at two schools in the southeastern US who participated in collaborative, sustained, whole-school professional development and their implementation of standards-based instructional practices are the focus of this study. Participants were involved in their second year of the professional development experience. The research question that was explored was “How are science teachers implementing standards-based instruction while participating in effective professional development experiences?” Data collected in the form of teacher interviews and classroom observations using an observation protocol. Findings indicate that even with effective professional development, teachers implement standards-based instructional practices at varying levels. The reasons for these differences are discussed and the role of teacher beliefs and the impact of beliefs, experience and support from administrators on professional development efforts are discussed. Implications for future science education reform stakeholders and professional development efforts are revealed.     

Mainstreaming the Hearing Impaired Student‐‐An Area of Preparation Responsibility for Teacher Training Programs: A Pilot Study

Interviewing, as an information‐gathering tool for prospective teachers of the deaf, was used to document the perspectives which deaf children, their parents, teachers and administrators bring to the mainstreaming process. Data revealed the different, and sometimes competing priorities of mainstreaming participants; these priorities are discussed in terms of their impact upon the success or failure of the mainstreaming process and the preparation responsibilities of teacher training programs.     

Alternative models of learning disabilities identification: considerations and initial conclusions

The final session of the National Research Center on Learning Disabilities (NRCLD) Responsiveness-to-Intervention (RTI) Symposium, "What are alternative models to LD identification other than RTI?" included four papers that discussed concerns over the exclusive reliance on an RTI approach to learning disability identification, considerations for analyzing proposed LD identification models, and various alternatives to LD identification. The work of the participating panelists is summarized in this discussant paper, and next steps for the NRCLD in light of these presentations are suggested.     

A model for making decisions about ethical dilemmas in student assessment

In this mixed-methods study we investigated the development of a generalized ethics decision-making model that can be applied in considering ethical dilemmas related to student assessment. For the study, we developed five scenarios that describe ethical dilemmas associated with student assessment. Survey participants (i.e., educators) completed an online survey to express their decision-making process when faced with ethical dilemmas relating to student assessment. Based on the literature and the educators’ written responses to the scenarios, elements to consider in an ethics decision-making model related to student assessment include the following: (1) the critical incident giving rise to the ethical dilemma; (2) identification of the conflict elements; (3) decisions about the ethicality of the elements; (4) justification of the decisions; (5) implications; and (6) alternative suggestions. This model offers guidance to educators in considering the dimensions of an ethical dilemma in assessment prior to making a decision.     

Parent-daughter transmission of the androgen receptor gene as an explanation of the effect of father absence on age of menarche

Based on an evolutionary theory of socialization, Belsky and colleagues proposed that girls exposed to a stressful environment, especially when due to father absence in the first 7 years of life, showed an early onset of puberty, precocious sexuality, and unstable relationships as adults. The authors of this article examined an alternative explanation that a variant X-linked androgen receptor (AR) gene, predisposing the father to behaviors that include family abandonment, may be passed to their daughters causing early puberty, precocious sexuality, and behavior problems. The results of a study of 121 White males and 164 White females showed a significant association of the short alleles of the GGC repeat polymorphism of the AR gene with a range of measures of aggression and impulsivity, increased number of sexual partners, sexual compulsivity, and lifetime number of sex partners in males; and paternal divorce, father absence, and early age of menarche in females. These findings support a genetic explanation of the Belsky psychosocial evolutionary hypothesis regarding the association of fathers' absence and parental stress with early age of onset of menarche and early sexual activity in their daughters. A genetic explanation of the father absence effect is proposed in which fathers carrying the AR alleles are more likely to abandon a marriage (father absence) and pass those alleles to their daughters in whom they produce an earlier age of menarche and behavioral problems.     

Teaching the design and interpretation of graphs through computer-aided graphical data analysis

Graphs are one of the primary means of exploration and communication in the practice of science, but students in science laboratories are customarily taught only the low-level mechanics of constructing a single kind of graph when given a table of information. The use of a microcomputer can relieve the drudgery of plotting, allowing students to pursue higher-level issues in the design and interpretation of graphs through repeated “thought experiments.” We introduced computer-assisted graphical data analysis to inner-city high school students with weak math and science backgrounds, emphasizing the dynamic manipulation of various kinds of graphs to answer specific questions. Drawing on extensive recordings and classroom observations, we describe examples of the performance of these students on open-ended problem-solving tasks in which graphs can be used to arrive at meaningful answers to applied data analysis problems.     

Summation of undetected excitation following extinction of the CER

The effects of compounding two conditioned stimuli (CSs), each of which had been extinguished to varying degrees in different groups of rats given identical acquisition training, was examined within the conditioned emotional response paradigm. Greater suppression to the compound than to the individual CSs was observed following 6, 12, 48, 72, and 96 stimulus extinction trials, although after only 12 extinction trials suppression to the individual stimuli was no longer observed. The amount of compound suppression decreased progressively as the number of extinction trials increased until, after 120 extinction trials on each stimulus, the compound no longer elicited observable suppression. Control group data indicated that the observed summation effect could not be attributed to disinhibition. The possible role of the summation of undetected excitation in studies examining configurai conditioning, avoidance conditioning and reinstatement is discussed briefly.     

Toddlers' Attachment Security to Child-Care Providers: The Safe and Secure Scale

Attachment relationships of toddlers (N = 45) to their child-care providers were investigated. Children's behaviors with their mothers were observed at home at 24 months and with their child-care providers at 26 months. Attachment Q-Sort procedures were used at home (90 items) and in child care (78 items); the latter yielded a 15-item Safe and Secure Scale describing the safe haven and secure base functions of attachment relationships in child care—being able to (a) seek and receive positive attention, (b) feel safe and protected, (c) receive support for exploration, (d) receive consolation when distressed, and (e) seek and accept assistance. Independent observational measures of child-care quality also were obtained at 24 months. As hypothesized, the Safe and Secure Scale was related to proximal rather than distal indicators of child-care quality, and it was a stronger measure than the child-caregiver Q-security score that was based on all 78 items. Child-mother and child-caregiver security were significantly related.     

An approach to psychosexual counselling

Summary In considering in this paper the origins, development and need for psychosexual counselling to be an integral part of the provision of a counselling service, one must not lose sight of the fact that some higher educational institutions still have no general counselling provision.It is interesting to note that in the UK at a time when the age of consent and voting age were lowered to eighteen years (Family Law Reform Act, 1969, operational 1970 and Representation of the People Act, 1969), and students were rejecting the idea of wardens and academic tutors acting in loco parentis, the National Union of Students (at their annual conference in 1969) passed a resolution pressing for Counselling Services to be established in each higher educational institution-staffed by fully trained personnel, Milner (1974). Nine years later this resolution has not yet been fully implemented.The university community represents a cross-section of the population, any of whom may have a psychosexual problem and seek help from the counselling service. Counsellors must be trained to treat psychosexual problems as part of their normal range of activities.Storr (1960) points out that it is The individual as well as the disease that needs treatment. This applies in counselling as it does in medicine, so that the counsellor should be able to treat the individual as a whole, and at the same time treat his psychosexual problem.University of Reading
