The prevalence and seriousness of incestuous abuse: Stepfathers vs. biological fathers

Analysis of interviews obtained from a random sample of 930 adult women in San Francisco revealed that 17% or one out of approximately every six women who had a stepfather as a principal figure in her childhood years, was sexually abused by him. The comparable figures for biological fathers were 2% or one out of approximately 40 women. In addition, when a distinction was made between Very Serious Sexual Abuse (including experiences ranging from forced penile-vaginal penetration to non-forceful attempted fellatio, cunnilingus, and anal intercourse) and other less serious forms, 47% of the cases of sexual abuse by stepfathers were at the Very Serious level of violation compared with 26% by biological fathers. Possible explanations for these startling discrepancies are discussed, and some of the implications for remarriage are considered.     

Learning Multi‐unit Number Concepts and Understanding Decimal Place Value

Research indicates that many errors in secondary school mathematics can be attributed to lack of understanding of decimal place value. Recently it has been suggested that this arises from an underlying weakness in integer place value concepts and perception of multidigit numbers in unitary terms rather than base ten, multi‐unit structures. Development of place value and multidigit number concepts was examined in individual interviews with 262 primary school pupils, aged between 7 and 12 years, using subjects’ concrete representations of written numerals and associated verbal explanations. Almost all the children had some understanding of integer place value; most older children had multi‐unit concepts of three‐ or four‐digit numbers; but two‐digit numbers, especially values of 20 or less, were frequently perceived in terms of units by all age groups. This was particularly common for the value ten where 55% of subjects displayed unitary concepts. Implications for understanding and teaching decimal place value are discussed.     

A Longitudinal Study of Children’s Developing Knowledge and Reasoning in Science

The growth in science understanding and reasoning of 12 children is being traced through their primary school years. The paper reports findings concerning children’s growing understandings of evaporation, and their changing responses to exploration activities, that show the complexity and coherence of learning pathways. Children’s responses to identical explorations of flight, separated by two years, are used to explore the interactions between conceptual knowledge and scientific reasoning, and the manner in which they change over this time. The paper discusses the particular insights afforded by a longitudinal study design, and some attendant methodological issues.     

Towards a model for the assessment of student boredom and boredom proneness in the UK higher education context

Recently identified as an academic ‘achievement emotion’, boredom has long been implicated as a factor contributing adversely to student attainment across a diverse range of formal educational settings. Despite this, the study of boredom, particularly among students in higher education, remains a relatively neglected and underdeveloped field. In this article, and following a systematic review of the research literature, we present details of a new research instrument and diagnostic tool derived from Farmer and Sundberg’s Boredom Proneness Scale (BPS), specifically intended to assess or measure the recurring propensity or habitual disposition of students to becoming bored particularly within the UK higher education context (e.g. further education, university college and university provision). Referred to here as the BPS-UKHE, to distinguish it from its predecessor, the statistical validity and reliability as well as educational relevance and meaningfulness of the BPS-UKHE is established, confirming its multidimensional nature with subscales (Tedium, Time, Challenge, Concentration and Patience) reflecting boredom’s acknowledged cognitive, affective, motivational and behavioural components. Full-scale, five-factor and three-factor ‘short-form’ solutions are offered, the immediate utility of which in identifying students more prone to boredom than others and gauging emotional response is demonstrated. The BPS-UKHE has application in many areas and is considered a valuable tool in relation to the UK student engagement agenda, its scales and potential, as well as theoretical underpinning, available for empirical use and critical comment.     

PREDICTING MATHEMATICS ACHIEVEMENT: THE INFLUENCE OF PRIOR ACHIEVEMENT AND ATTITUDES

Achievement in mathematics is inextricably linked to future career opportunities, and therefore, understanding those factors that influence achievement is important. This study sought to examine the relationships among attitude towards mathematics, ability and mathematical achievement. This examination was also supported by a focus on gender effects. By drawing on a sample of Australian secondary school students, it was demonstrated through the results of a multivariate analysis of variance that females were more likely to hold positive attitudes towards mathematics. In addition, the predictive capacity of prior achievement and attitudes towards mathematics on a nationally recognised secondary school mathematics examination was shown to be large (R ²  =  0.692). However, when these predictors were controlled, the influence of gender was non-significant. Moreover, a structural equation model was developed from the same measures and subsequent testing indicated that the model offered a reasonable fit of the data. The positing and testing of this model signifies growth in the Australian research literature by showing the contribution that ability (as measured by standardised test results in numeracy and literacy) and attitude towards mathematics play in explaining mathematical achievement in secondary school. The implications of these results for teachers, parents and other researchers are then considered.     

The Semiotic Function of a Bridging Representation to Support Students’ Meaning-Making in Solution Chemistry

Research in Science Education - Many researchers have reported that bridging analogies can productively support students’ scientific meaning-making. How this can be understood semiotically...     

Sources of Individual Differences in Children's Understanding of Fractions

Longitudinal associations of domain‐general and numerical competencies with individual differences in children's understanding of fractions were investigated. Children (n = 163) were assessed at 6 years of age on domain‐general (nonverbal reasoning, language, attentive behavior, executive control, visual‐spatial memory) and numerical (number knowledge) competencies; at 7 years on whole‐number arithmetic computations and number line estimation; and at 10 years on fraction concepts. Mediation analyses controlling for general mathematics ability and general academic ability revealed that numerical and mathematical competencies were direct predictors of fraction concepts, whereas domain‐general competencies supported the acquisition of fraction concepts via whole‐number arithmetic computations or number line estimation. Results indicate multiple pathways to fraction competence.     

Source-code plagiarism in universities: a comparative study of student perspectives in China and the UK

There has been much research and discussion relating to variations in plagiaristic activity observed in students from different demographic backgrounds. Differences in behaviour have been noted in many studies, although the underlying reasons are still a matter of debate. Existing work focuses mainly on textual plagiarism, and most often derives results by studying (small) groups of overseas students studying in a Western context. This study investigates understanding of source-code plagiarism (i.e. plagiarism of computer programmes) amongst university students in China. The survey instrument was a Chinese translation of a survey previously administered in English in the UK. This paper reports the results of the exploratory survey conducted in China, and compares these results to those from a parallel survey conducted in the UK. The results show that there is a significant difference in understanding between the respondents from the two surveys, and suggest topics which a future and more comprehensive study may focus on.
