Erroneous concerns about child sexual abuse

AIM: To assess the incidence and nature of concerns about sexual abuse, with particular reference to erroneous concerns of sexual abuse made by children. METHODS: A review of case notes of all child sexual abuse reports to the Denver Department of Social Services over 12 months. Cases were put into four groups: substantiated, not sexual abuse, inconclusive and erroneous accounts by children. RESULTS: 551 cases were reviewed. Forty-three percent were substantiated, 21% were inconclusive and 34% were not considered to be abuse cases. There were 14 (2.5%) erroneous concerns emanating from children. They comprised three cases of allegations made in collusion with a parent, three cases where an innocent event was misinterpreted as sexual abuse and eight cases (1.5%) of false allegations of sexual abuse.CONCLUSION: Erroneous concern of sexual abuse from children are uncommon. The four categories of concern in this study, in contrast to the simple classification of substantiated and unsubstantiated, provide a means of encouraging open minded assessments of the typical concerns which a child protection agency receives.     

Parental training and involvement in sexuality education for students who are deaf

The study examined whether schools for the deaf were providing services to assist parents in communicating with their children about sexuality (including sexual signs) and whether parents were involved in the sexuality education curriculum within their child's school. The Sexuality Curriculum Questionnaire for Educators of Students Who Are Deaf (Getch & Gabriel, 1998) was completed by 71 educators teaching sexuality curricula in schools for the deaf across the United States. Results indicated that parents were more likely to be involved in approval and development of their children's sexuality education than to receive assistance with sexuality education from the schools. Although the level of parental participation in curriculum development and approval is encouraging, the number of parents actually participating in curriculum development and approval remains low.     

Assessment and student participation: ‘choice and voice’ in school principal accounts of schooling territories

Schooling territories are bounded spaces where policies, bodies, practices, and discourses meet and collide. It is well documented in assessment literature that students who are active decision-makers understand their learning processes and have the necessary wherewithal to access support across schooling spaces. These spaces are co-produced through interrelationships, where youth participation is associated with power, voice, democratic citizenship, legal entitlement, empowerment, motivation and self-confidence. Recognising the growing pedagogical emphasis on locating students as responsible for their own learning, we consider how assessment practices constitute enabling and constraining schooling territories. Assessment for learning (AfL) can be linked with emancipatory practices in schooling territories where learner agency is co-produced through socio-material classroom relations. We use principal comments to map a range of interrelated schooling territories as a relational cartography of spatialised practices and student participation in AfL. Mostly, these territories are teacher imagined and defined, constructed through schooling and policy frameworks, and determined through the use of student achievement and student voice data. These conceptualised schooling spaces are interrogated to consider the positionality of students within AfL-related territories. While choice and participation may seem emancipatory, we reveal that AfL practices can serve a rarely acknowledged process of affirming territorial power.     

Rates of responding in the pigeon generated by simple and complex schedules which provide the same rates of reinforcement

Four pigeons pecked for food reinforcement on variable interval 1-min schedules and on the variable-interval 1-min components of multiple, concurrent, and pseudoconcurrent schedules. The pseudoconcurrent schedule provided only one schedule of reinforcement; but, any reinforcer could be collected by responding on either of two keys. The rate of responding generated by the variable interval schedule was not greater than the rates of responding generated by the components of the complex schedules. But, the rate of reinforcement obtained from the variable interval schedule was greater than the rates of reinforcement obtained from the components of the multiple schedule. These results may contradict the equation proposed by Herrnstein (1970). The equation predicts that the rate of responding generated by a schedule of reinforcement will be greater when the schedule appears alone, than when it appears as one component of a complex schedule.     

Outcomes of first year secondary students in a computer‐augmented physics program on measurement

Measurement is a foundational topic in secondary school physics that must be taught to all beginning secondary education students in Kenya. The secondary level offers education for students who are aged between 12‐ and 18‐years‐old. Physics teachers in the Rift Valley province identified the topic of measurement as an area that is difficult to teach through traditional methods. This study explored the effectiveness of a computer‐augmented physics (CAP) program on teaching the topic of measurement to first year secondary students. A total of 118 secondary education students (65 males and 53 females) participated in the study. They were randomly selected and randomly assigned to three similar classrooms situated in three schools easily accessible by the Njoro‐Menengai and Nakuru‐Marigat roads better and served as the treatment and control groups. Except for the treatment group, all groups received the same course content for a period of six weeks. The findings of the study affirmed the impact of innovation on the students’ learning outcomes in that the mean gains of the participants in the CAP treatment were significantly higher than that of their counterparts in the regular program. Also, the results indicated that the mean differences between the experimental group and the control group were statistically significant in favour of the treatment group. The findings also showed no relationship between the participants’ gender and their learning outcomes. The study concludes that the use of the computer to augment conventional physics teaching has major implications for secondary physics in this area.     

From natural numbers to numbers and curves in nature - II

In this second part of the article we discuss how simple growth models based on Fibbonachi numbers, golden section, logarithmic spirals, etc. can explain frequently occuring numbers and curves in living objects. Such mathematical modelling techniques are becoming quite popular in the study of pattern formation in nature.     

Salivary cortisol as a predictor of socioemotional adjustment during kindergarten: a prospective study

This study, based on a sample of 172 children, examined the relation between average afternoon salivary cortisol levels measured at home at age 4.5 years and socioemotional adjustment a year and a half later, as reported by mothers, fathers, and teachers. Cortisol levels were hypothesized to be positively associated with withdrawal-type behaviors (e.g., internalizing, social wariness) and inversely related to approach-type behaviors, both negative and positive (e.g., externalizing, school engagement). Higher cortisol levels at age 4.5 predicted more internalizing behavior and social wariness as reported by teachers and mothers, although child gender moderated the relation between cortisol and mother report measures. An inverse relation was found between boys' cortisol levels and father report of externalizing behavior. A marginal inverse relation was found between child cortisol levels and teacher report of school engagement. Behavior assessed concurrently with cortisol collection did not account for the prospective relations observed,suggesting that cortisol adds uniquely to an understanding of behavioral development.
