Fairness and Consequential Validity of Teacher Work Samples

Acknowledging the necessity to establish the fairness and consequential validity of teacher candidate performance assessments when they are used to make high-stakes decisions impacting entry into the profession, we investigated whether there were any adverse results from the use of the Renaissance Teacher Work Sample (TWS) assessment at two universities as a consequence of the age, gender, or race/ethnicity of teacher candidates. We also investigated education program and program entrance requirements, such as Praxis I scores, and measures of grade point average, as general predictors of TWS success. The findings indicated no disparate impact or adverse consequences based on the gender, age, or race/ethnicity of the teacher candidates. Selected variables did predict a moderate amount of the variance of the TWS total scores of both preinterns and student-teaching interns. The process used to determine the value implications of the results was also discussed.     

Self-belief does make a difference: A reciprocal effects model of the causal ordering of physical self-concept and gymnastics performance

Abstract

A large body of research in support of the reciprocal effects model of causal ordering demonstrates that prior academic self-concept predicts subsequent academic achievement beyond what can be explained in terms of prior achievement. Here we evaluate the generalizability of this support for the reciprocal effects model to a physical activity context in which achievement is reflected in gymnastics skills on a standardized gymnastics performance test evaluated by expert judges. Based on the responses of 376 adolescents collected at the start (T1) and end (T2) of a gymnastics training programme, there is support for a reciprocal effects model in which there are significant paths leading from both T1 gymnastics self-concept to T2 gymnastics skills and from T1 gymnastics skills to T2 self-concept. Although there were gender and age effects (girls and older participants had better gymnastics skills, boys had higher self-concepts), multiple group structural equation models indicated that support for the reciprocal effects model generalized over responses by boys and girls. In summary, self-concept and performance are both determinants and consequences of each other.     

Specificity of a Maximal Step Exercise Test

To adhere to the principle of “exercise specificity” exercise testing should be completed using the same physical activity that is performed during exercise training. The present study was designed to assess whether aerobic step exercisers have a greater maximal oxygen consumption (max VO₂) when tested using an activity specific, maximal step exercise test (SET; arms and legs) versus a maximal running test (legs only). Female aerobic step exercisers (N=18; 20.7 ± 1.5 years) performed three maximal graded exercise tests (GXTs): 2 SETs; 1 treadmill test (TMT). The SET consisted of six 3-min progressive stages of alternate lead, basic step, basic step with biceps curls, knee raise with pull-down, repeater knee with pull-down, lateral lunge with pull-down, and side squat with shoulder presses. Stepping rate was 32 steps· min^?1 on an 8-in (20.32 cm) step for stages 1–3, and a 10-in (25.4 cm) step for stages 4–6. Submaximal and maximal heart rate (HR) and oxygen consumption (VO₂) were recorded at the end of each stage. Test–retest reliability for the first five stages of the SET ranged from .91 to .97 for HR, and from .84 to .96 for VO₂. Maximal HR was significantly greater (p =.0001) for the SET (200 ± 6.2 beats·min^?1) as compared to the TMT (193 ± 7.9 beats·min^?1). No significant difference was found for max VO₂ (42.9 ± 8.5, 41.2 ± 5.9 ml·kg^?1·min^?1, p =.14). The SET was a valid and reliable protocol for assessing responses of these aerobic step exercisers; however, max VO₂ from a TMT did not differ significantly from the SET. Conversely, max HR obtained from the criterion TMT was 7 beats·min^?1 lower than from the SET. If a training HR for step exercise (arms and legs exercise) is prescribed based on the max HR from treadmill exercise (legs only), then the training HR should be calculated from a TMT max HR that has been increased by 7 beats·min^?1 to obtain an intensity of step exercise comparable to that of running.     

Sending Minnie the Minx Home: Comics and reading choices

This paper reports on aspects of two qualitative studies which focused on children's interests in comics. The earlier study (Millard, 1997) was part of a larger survey of 254 boys' and girls' reading interests, sampled at the point of transition between primary and secondary school. The second study, which forms the main body of this paper, explores the reactions to a home-school comic lending library based in three primary classrooms over a period of seven weeks. Results from both studies are discussed in this paper and the implications for the development of the primary school literacy curriculum explored.     

Leading with intent: cultivating community conversation to create shared understanding

School improvement is a central focus for school leaders. Whilst measures such as high-stakes testing and other government accountability agendas have at times marred the discourse of school improvement, how schools develop their capacity to ultimately improve the core business of student learning remains important. As an extensive area of scholarship, much has been written to support leaders in improving learning and teaching in their school. Indeed, studies demonstrate the value of establishing schoolwide goals and expectations and the importance of using evidence to improve teaching practice. This article presents qualitative data from 4 independent schools in the state of New South Wales (NSW) Australia which suggest that whilst the concept of school improvement is not new, the capacity of schools to embrace some key concepts found in this area of study is limited. The article proposes that through cultivating conversations within their communities, schools can foster shared understanding and enhance their capacity for improvement.     

A Laboratory Experiment, Based on the Maillard Reaction, Conducted as a Project in Introductory Statistics

ABSTRACT: A simple laboratory experiment, based on the Maillard reaction, served as a project in Introductory Statistics for undergraduates in Food Science and Technology. By using the principles of randomization and replication and reflecting on the sources of variation in the experimental data, students reinforced the statistical concepts and techniques introduced to them in lectures before the experiment. The experiment was run simultaneously by several student groups, using the same materials. Comparing the results of their analyses of variance, students became aware of the difference between P values and significance levels in making statistical decisions. In the experiment, the complete randomized design was applied; however, it is easy to adjust the experiment to teach students simple regression and randomized block designs.     

Industry and Business Working with Education Through the Ages Within the UK

Abstract

The article looks at how, when major technologies appeared, from hand printing to data processing, via printing and broadcasting, ‘business’ or ‘companies’ or ‘industry’ responses involved education. The reasons for the response, it has to be said, often had a touch of self interest, but were none the less effective for that. This is continuing today as some of the examples cited indicate.
