Determinants of middle school students' intention to enroll in a high school science course: An application of the theory of reasoned action

The determinants of intentions to enroll in a high school science course were investigated, using the theory of reasoned action, among earth science students enrolled in a middle school located in a middle-income, suburban community in central Texas. The sample consisted of 5 of 14 eighth-grade earth science classes, randomly selected for this study. Classes contained Caucasian and minority students, male and female, of differing science abilities who were grouped according to general academic abilities—basic, average, and gifted and talented. The prediction of behavioral intention of sample participants was tested using four external variables, attitude, and subjective norm (Direct-Full Effects Model), attitude and subjective norm alone (Direct-Reduced Effects Model), and disaggregated data on attitude and subjective norm (Indirect Effects Model). Results of the study revealed attitude and subjective norm to be the sole predictors of behavioral intention for the aggregated data, but to be differentially effective for groups formed on the basis of sex, ethnicity, general ability, and science ability. Evidence is presented to show that the relative contributions of attitude and subjective norm to the prediction of behavioral intention varies among students depending upon their sex, ethnicity, general ability, and science ability. Results of the study are discussed in terms of increasing the enrollment of all students in elective science courses.     

Appreciated abroad, depreciated at home. The career of a radiochemist in Norway: Ellen Gleditsch (1879-1968)

Ellen Gleditsch (1879-1968) became Norway's first authority on radioactivity and the country's second female full professor. From her many years abroad--in Marie Curie's laboratory in Paris and at Yale University in New Haven with Bertram Boltram--she became internationally acknowledged and developed an extensive personal and scientific network. In the Norwegian scientific community she was, however, less appreciated, and her appointment as a professor in 1929 caused controversy. Despite the recommendation of the expert committee, her predecessor and his allies spread the view that Gleditsch was a diligent but outdated researcher with little scientific promise-a view that apparently persists in the Norwegian chemical community today. In addition to her scientific work, Gleditsch acquired political influence by joining the International Federation of University Women in 1920; she later became the president of both the Norwegian section and the worldwide organization. She worked in particular to establish scholarships enabling women to go abroad.     

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.     

Roles of assessment in secondary education: Participant perspectives

Performance pressure at both the institutional and individual level of secondary education has been identified as a pressure that is acknowledged all over Europe and raises questions about the extent to which agents in lower and upper secondary education interpret assessment in terms of either control or learning, or perhaps both. Drawing on empirical findings from two case studies in Denmark, the article focuses on the social roles of educational evaluation and assessment, and discusses the ways in which the local level interpretations of policy demands influence teaching and learning in secondary education. To enable an analysis of the understanding of different agents in the field, the article combines important sociological thinking with the basic distinction between assessment of programmes and assessment of individuals. Presuming that assessment practices bear the traces of the social structure that they both express and reproduce, the aim of this paper is to interrogate how the agents view and interpret such practices.     

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.     

A Maximal Graded Exercise Test to Accurately Predict VO2max in 18–65-Year-Old Adults

The purpose of this study was to develop an age-generalized regression model to predict maximal oxygen uptake (VO_2max) based on a maximal treadmill graded exercise test (GXT; George, 1996) George, J. D. 1996. Alternative approach to maximal exercise testing and VO_2max prediction in college students. Research Quarterly for Exercise and Sport, 67: 452–457. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]. Participants (N?=?100), ages 18–65 years, reached a maximal level of exertion (mean?±?standard deviation [SD]; maximal heart rate [HR_max]?=?185.2?±?12.4 beats per minute (bpm); maximal respiratory exchange ratio [RER_max]?=?1.18?±?0.05; maximal rating of perceived exertion (RPE_max)?=?19.1?±?0.7) during the GXT to assess VO_2max (mean?±?SD; 40.24?±?9.11 mL·kg^?1·min^?1). Multiple linear regression generated the following prediction equation (R?=?.94, standard error of estimate [SEE]?=?3.18 mL·kg^?1·min^?1, %SEE?=?7.9): VO_2max (mL·kg^?1·min^?1)?=?13.160?+?(3.314 × gender; females?=?0, males?=?1) ? (.131 × age) ? (.334 × body mass index (BMI))?+?(5.177 × treadmill speed; mph)?+?(1.315 × treadmill grade; %). Cross validation using predicted residual sum of squares (PRESS) statistics revealed minimal shrinkage (R_p ?=?.93 and SEE _p ?=?3.40 mL·kg^?1·min^?1); consequently, this model should provide acceptable accuracy when it is applied to independent samples of comparable adults. Standardized β-weights indicate that treadmill speed (.583) was the most effective at predicting VO_2max followed by treadmill grade (.356), age (?.197), gender (.183), and BMI (?.148). This study provides a relatively accurate regression model to predict VO_2max in relatively fit men and women, ages 18–65 years, based on maximal exercise (treadmill speed and grade), biometric (BMI), and demographic (age and gender) data.

Parents who hit and scream: Interactive effects of verbal and severe physical aggression on clinic-referred adolescents’ adjustment

The goals of this study were first, to delineate the co-occurrence of parental severe physical aggression and verbal aggression toward clinic-referred adolescents, and second, to examine the interactive effects of parental severe physical aggression and verbal aggression on adolescent externalizing and internalizing behavior problems. This research involved 239 referrals of 11- to 18-year-old youth and their dual-parent families to a non-profit, private community mental health center in a semi-rural Midwest community. Multiple informants (i.e., adolescents and mothers) were used to assess parental aggression and adolescent behavior problems. More than half of clinic-referred adolescents (51%) experienced severe physical aggression and/or high verbal aggression from one or both parents. A pattern of interactive effects of mother-to-adolescent severe physical aggression and verbal aggression on adolescent behavior problems emerged, indicating that when severe physical aggression was present, mother-to-adolescent verbal aggression was positively associated with greater adolescent behavior problems whereas when severe physical aggression was not present, the links between verbal aggression and behavior problems was no longer significant. No interactive effects were found for father-to-adolescent severe physical aggression and verbal aggression on adolescent adjustment; however, higher father-to-adolescent verbal aggression was consistently linked to behavior problems above and beyond the influence of severe physical aggression. The results of this study should promote the practice of routinely assessing clinic-referred adolescents and their parents about their experiences of verbal aggression in addition to severe physical aggression and other forms of abuse.     

Résolution de problèmes d’hydrodynamique face à un circuit concret — Comparaison des stratégies avant et après apprentissage

The aim of this piece of research is to study physical reasoning and problem solving strategies among novices before and after a learning treatment in the field of hydrodynamics problems. The study is designed to investigate the meaning of becoming more expert in a specific domain. The results show several changes among novices after the learning treatment. Types of physical reasoning strategies appear which were not observed at the pretest. Nevertheless these correct reasoning strategies coexist with misconceptions (local reasoning). As far as general strategies are concerned, some changes are also observed. At the pretest most subjects proceed by trial and error. At the post-test their approach is guided by specific physical reasoning strategies, even if sometimes erroneous. Although the learning treatment did not deal with these various aspects, it appears that subjects experience a more rigourous approach, controlling much better than earlier the effects of their actions on the circuit. It seems as though, at the time of the pretest, the absence of domain-specific knowledge prevented students from applying a rigourous experimental approach, in principle independent of the domain concerned.
