Does student-centered instruction engage students differently? The moderation effect of student ethnicity

Student-centered instruction is featured in reforms that aim to improve excellence and equity in mathematics education. Although research on stereotype threat suggests that student-centered instruction may have differential effects on racial minority students, the relationship between student-centered mathematics instruction and student engagement remains understudied. This study examined the relationship between student-centered mathematics instruction and adolescents’ behavioral, cognitive, emotional, and social engagement in mathematics and whether the relationship differed by ethnicity. The authors used a multilevel path analysis with data from 3,883 sixth- to 12th-grade students (52.1% girls, 38.2% eligible for free/reduced lunch, 66.1% Caucasian, 23.8% African American, 7.2% multiracial, and 2.9% Asian American). The results showed that student-centered instruction was positively related to all dimensions of mathematics engagement. However, the positive association between student-centered mathematics instruction and student engagement was weaker for African American students. This study provides empirical evidence for the benefits of student-centered instruction while suggesting differential effects based on students’ ethnicity.     

The Evaluation of Student Fitness Levels in Exercise Science and Physical Education Teacher Education Programs

The debate on whether kinesiology students should undergo fitness testing is controversial. Some are strong proponents of fitness testing, while others are in strong opposition. As advocates for fitness testing among kinesiology majors, we aimed to assess the fitness levels of Exercise Science and Physical Education Teacher Education majors and evaluate current physical education teacher education (PETE) fitness criterion. One hundred and sixteen participants (males N = 49; females N = 67) underwent health-related fitness assessments. 37% of males and 51% of females met PETE’s fitness criteria. Both groups performed significantly better in body fat percentage and upper body strength than PETE’s acceptable (average) standards; however, most were significantly lower than target (above average) standards. Presented are fitness passing criteria for PETE majors and fitness reporting that aids in improved fitness tracking and accountability. We also highlight the need for NASPE and SHAPE America to clearly define fitness expectations for PETE majors and encourage other kinesiology faculty to consider implementing fitness testing in their programs.

Diabetic cardiomyopathy and reactive oxygen species (ROS) related parameters in male and female rats: A comparative study

Studies were carried out to examine and compare the effects of alloxan-diabetes on reactive oxygen species (ROS) related parameters in the heart from male and female rats. Effects of insulin treatment were also evaluated. The diabetic state severely compromised the ROS defense mechanism in the cardiac tissue and the effects were more pronounced in the female than in the male rats. There was several fold increase in the xanthine oxidase (XO) activity in general and the magnitude of increase was higher in the females; insulin treatment resulted in further increase in the XO activity. The glucose-6-phosphate dehydrogenase (G6PDH) and catalase activities decreased and the reduced glutathione (GSH) content in mitochondria was completely depleted in diabetic state with significant decrease in the GSH levels in the post-mitochondrial fraction; the effect was more pronounced in the females. The superoxide dismutase (SOD) and glutathione peroxidase (GPox) activities increased in the diabetic state to a greater extent in male rats. Insulin treatment had restorative action only on some parameters. In conclusion, our results suggest that diabetic state may further compromise the weak ROS defense systems in the heart thus initiating a lesion at the level of mitochondria which ultimately leads to cardiomyopathy and the effects are especially more pronounced in the females. Our results also pointed out that insulin treatment was ineffective in restoring ROS related parameters.

An algorithm for Eigenvalue assignment in multi-input systems

This paper describes a computational method for solving the problem of eigenvalue assignment in a multi-input linear system. The given system is first reduced to an upper block Hessenberg form by means of orthogonal state coordinate transformations. It is then shown how a sequence of state feedback matrices and orthogonal state coordinate transformations can be applied to obtain a block triangular structure for the resulting state matrix, where the matrices on the diagonal are square matrices in upper Hessenberg form and of dimensions equal to the controllability indices of the multi-input system. Furthermore, the structure of the corresponding input matrix is such that the problem of eigenvalue assignment in the multi-input system can be reduced to several single-input eigenvalue assignment problems where the dimensions of the single-input systems are equal to the controllability indices of the multi-input system.     

Networks of knowledge, matters of learning, and criticality in higher education

Higher education in the UK has become preoccupied with debates over the authority of knowledge and of criticality. In this article we argue that approaches to knowledge in higher education might benefit from a network sensibility that foregrounds the negotiated processes through which the material becomes entangled with the social to bring forth actions, subjectivities and ideas. We draw from a set of analytic perspectives that have arisen from actor-network theory traditionally associated with the writings of Bruno Latour. These approaches emphasise the contingent in knowledge production, even to claim that objects, knowledge or otherwise, come into being through enactment as effects within particular webs of relations. What becomes visible in such analysis is the precarious fragility of concepts and categories often assumed to be immutable, and the work required to establish their stability. We argue that this actor-network analysis helps to move away from a focus on separate entities and individuals to understand their material relationality. This analysis also foregrounds the controversies that tend to be foreclosed in what Latour calls ‘matters of fact’, and makes visible the different worlds in which knowing is evoked in practice. From this departure point the issue of interest is not which knowledge accounts are superior but how and when particular accounts become more visible or valued, how they circulate, and what work they perform in the process. These approaches afford a criticality that we argue open important entry points for rethinking curriculum, teaching and learning in higher education.     

Fifth graders' science inquiry abilities: A comparative study of students in hands‐on and textbook curricula

A large number of American elementary school students are now studying science using the hands‐on inquiry curricula developed in the 1990s: Insights; Full Option Science System (FOSS); and Science and Technology for Children (STC). A goal of these programs, echoed in the National Science Education Standards, is that children should gain “abilities to do scientific inquiry” and “understanding about scientific inquiry.” We have studied the degree to which students can do inquiries by using four hands‐on performance assessments, which required one or three class periods. To be fair, the assessments avoided content that is studied in depth in the hands‐on programs. For a sample of about 1000 fifth grade students, we compared the performance of students in hands‐on curricula with an equal number of students with textbook curricula. The students were from 41 classrooms in nine school districts. The results show little or no curricular effect. There was a strong dependence on students' cognitive ability, as measured with a standard multiple‐choice instrument. There was no significant difference between boys and girls. Also, there was no difference on a multiple‐choice test, which used items released from the Trends in International Mathematics and Science Study (TIMSS). It is not completely clear whether the lack of difference on the performance assessments was a consequence of the assessments, the curricula, and/or the teaching. © 2006 Wiley Periodicals, Inc.

Teaching Now with the Living: A Dialogue with Teachers Investigating Contemporary Art Practices

The Education Departments of Tate Modern and Goldsmiths College collaborated with a group of teachers to find out what they understood by the term ‘contemporary art’ and to discover the conditions that enable contemporary art practices in the classroom. We explored questions with eleven teachers, from both primary and secondary schools, during the Autumn of 2004. Although the cultural/ethnic context of the schools the teachers worked within was diverse, they shared a commitment to working with contemporary art in the classroom and exploring new pedagogies in this field. Their engagement with contemporary art and their revealing and compelling experiences are documented, contextualized and summarized. Samples of the discussions form the substance of this article. This is preceded by an analysis of the success of socially‐orientated contemporary art in the wider global context and its contrast with the omission of these practices in many schools. Conclusions have been tentatively drawn about how the curriculum may be better served by the use of contemporary art, as well as the means by which new learning methods may be facilitated.
