Validity of Palpation Recovery Pulse Rate to Estimate Exercise Heart Rate Following Four Intensities of Bench Step Exercise

Abstract

Previous investigations regarding activity during the post-knowledge of results (KR) interval have considered the performance of interference groups over KR-supplied acquisition trials as indicative of effects upon learning. The absence of transfer tests in these studies, however, preclude such an assumption. Indeed, the use of a retention test in the present investigation (no-KR trials following an interpolated phase) provided evidence suggesting that, while activity during the post-KR interval is detrimental to performance, no such assumption can be made regarding this effect upon learning. These findings are discussed relative to recent arguments that some of the commonly accepted “Laws of KR” may be contradictory when applied simultaneously to motor learning and performance.

Longitudinal effects of RtI implementation on reading achievement outcomes

Because several studies have investigated student outcomes in schools implementing Response to Intervention (RtI), relatively little research has investigated the impact of implementation on students’ long‐term achievement outcomes (i.e., several years after exposure). The purpose of this study was to describe one elementary school's RtI implementation process and to examine students’ long‐term reading comprehension outcomes following their exposure to various phases of implementation. Four cohorts of students who experienced different implementation phases (i.e., a baseline condition or Phases I, II, or III of implementation) during Grade 2 were subsequently followed across Grades 3, 4, and 5 to examine their outcomes on two reading comprehension measures. Results indicated that students who experienced the early phases of RtI implementation (i.e., Phases I and II) during Grade 2 generally had higher mean comprehension scores in Grades 4 and 5 than students in the baseline condition. Implications for practice and future research are discussed.     

Emotion regulation and academic perceptions in adolescence

Although studied extensively in the field of adolescent mental health, the role of emotion regulation (ER) in the academic functioning of adolescents is not well understood. This study examined the role of ER in adolescents’ perceptions of themselves and their learning environments. We compared adolescents with high and low levels of ER on perceptions of school achievement and attitudes towards school and their perception of their parents’ academic involvement. Students completed surveys about perceptions of their learning and parental involvement, as well as their ER abilities. Results indicated that students with higher emotion dysregulation endorsed more negative self-perceptions of their own academic abilities, had more negative attitudes towards school, and rated their mothers and fathers as more controlling in relation to their learning. These results demonstrate the importance of ER in the academic context, particularly in the home learning environment.     

Preparing teachers to create a mainstream science classroom conducive to the needs of English‐language learners: A feminist action research project

A feminist action research team, which consisted of a science educator, an English‐language learner (ELL) educator, a first‐year science teacher, and a graduate assistant, set a goal to work together to explore the process a beginning teacher goes through to establish a classroom conducive to the needs of middle‐level ELL learners. The guiding questions of the study were answered by gathering a wealth of data over the course of 5 months and taken from the classroom, planning sessions, and researchers and students. These data were collected by observations, semistructured interviews, and written document reviews. The progressive analysis ultimately revealed that: (a) successful strategies a beginning teacher must utilize for teaching middle‐level ELL children in a mainstream classroom involve complex structural considerations that are not part of the teacher's preparation; (b) learning increases for all children, but there are differences in learning achievement between ELL and non‐ELL children; and (c) student and peer feedback proved to be an effective means of enhancing the growth of a beginning teacher seeking to increase her skills in teaching ELL learners. The experiences and findings from this project have implications for teacher preparation programs committed to preparing educators to teach science to all children. © 2005 Wiley Periodicals, Inc.

Sociotechnical co-evolution of an e-Learning innovation network

This paper reports on a longitudinal study of a network of 10 special education needs schools over a span of 11 years that leveraged the opportunity offered by a government-funded e-learning pilot scheme initiative to further their efforts in providing the same educational opportunities to their students as those in mainstream schools. The trajectory of this network’s evolution shows that its robustness lies in the joint leadership network among the schools, and the insight and agency that this leadership network exhibited in the intentional exploration and crafting of a social structure and mechanism to support innovative developments in technology and pedagogical innovation, which we refer to as sociotechnical co-evolution. By adopting a sociotechnical system framework to analyse the changes at the landscape, regime and niches levels, we show that in fact landscape factors play a crucial role in shaping the innovation trajectory through its influence on the niches. Network leadership, within-school leadership and organizational infrastructures evolve and play an important role in the co-construction of the sociotechnical regimes needed to bring about deep and widespread changes in pedagogical practice.     

Developing Multicultural Counseling Competencies Through Experiential Learning

Counselor educators are challenged to prepare students for working with culturally diverse clients. The recent attention paid to multicultural counseling competencies has defined domains of learning; however, training methods to support the development of multicultural counseling competencies have received less emphasis. This article focuses on experiential learning as a teaching and learning methodology to increase students' multicultural counseling competencies. The authors outline ethical and practical suggestions for using experiential learning in multicultural counseling curriculum.     

The Community of Practice among Mathematics and Mathematics Education Faculty Members at an Urban Minority Serving Institution in the U.S.

Using narrative inquiry as a research method, four mathematics and mathematics education faculty members explored the integration of theoretical perspectives into their personal narratives as they developed a community of practice. Initially their focus was strictly on improving their students’ mathematical knowledge. As their community of practice matured, however, their work took on a larger meaning as they contributed to the institution’s strategic goal of raising the annual dollar amount of external funding and to the development of their personal and collective identities. This unusual level of inter-departmental collaboration has been recognized by the institution’s highest administrators, who have called upon its members to develop new, collaborative partnerships with regional school districts and community colleges.     

Integration of Disabled Students into Regular Classrooms in the United States and in Victoria,Australia

The authors recently visited schools in Victoria, Australia, which were representative of those involved in educating students with disabilities. This paper compares beliefs and values in the US and Victorian systems as they relate tothe education of students with disabilities. It is suggested from the perspective of a practitioner how these varying beliefs are orchestrated in public policy, with comparisons being made of important differences in practice in the education of disabled students in the two systems.     

Similarities and differences in teachers' beliefs about effective teaching of mathematics: Japan and Hawai'i

This paper examines the similarities and differences in beliefs about the effective teaching of mathematics held by teachers from two different socio-cultural backgrounds: Tokyo, Japan and Hawai'i, U.S.A. Data were collected using a part of the Teacher General Classroom Process Questionnaire (Grade 8) of the Second IEA Mathematics Study. Validation and interpretation of the data collected were based on classroom observations and interviews. The results indicate that while there are some similarities in beliefs of what constitutes effective teaching, the differences are greater. These differences appear to reflect the difference in the teachers' socio-cultural environment. In particular, the differences appear in classroom management, face-saving strategies, and providing for individual needs and differences.
