The use of motor activity learning in the development of science concepts with slow learning fifth grade children

This study compared the motor activity technique of learning, using physical education activities, with traditional ways of developing science concepts with fifth grade slow learning children. Two groups of ten children each were equated on the basis of pretest scores. Both groups were taught by the same classroom teacher. One group was taught through motor activity learning and the other by traditional procedures. Both groups were retested after a two-week teaching period, and again after a three-month extended interval. The difference in the posttest scores favored the motor activity learning group, p < .01 (t = 4.33, df 9). The difference in the extended interval test also favored the same group, p < .001 (t = 6.37, df9). Using the differences in test scores as criteria for learning, the children in the motor activity learning group learned and retained significantly more than those in the traditional group.     

Effect of matrine and carvedilol on collagen and MMPs activity of hypertrophy myocardium induced by pressure overload

INTRODUCTION Matrine, a monomer of traditional Chinese medi-cine, comes from leguminosae plants such as Kusheng, is quinoilizidine with four-loop and molecular formula of C15H24N20. Matrine has been proved to have anti-arrhythmia (Xu et al., 2004), anti-hypoxia and decreasing heart rate effects (Zhang et al., 1990a; 1990b) in many animal experiments, and has the role of inducing calmness (Luo et al., 2001) and lowering body temperature (Tao and Wan, 1992). Traditional Chinese medicin…     

Overcoming Junior High School Students' Misconceptions About Microscopic Views of Phase Change: A Study of an Analogy Activity

This study was conducted to examine the effectiveness of an analogy activity, which was designed to overcome junior high students' misconceptions about the microscopic views of phase change. Eighty Taiwanese 8th graders were randomly assigned to either a control group or an experimental group. For the control group, the subjects were instructed through traditional teaching whereas for the experimental group, an analogy activity was conducted on students. This specific analogy activity was presented in the form of role-playing in which students acted as particles and worked together to perform the conditions of phase changes. Through analyzing these students' drawings of the atom arrangements for the three states of some substances, it was found that the students of experimental group, though in many cases, did not perform statistically better than did those of control group in an immediate posttest. The comparisons of a delay test between these two groups indicated that the analogy activity had clearly positive impacts on students' conceptual change on these scientific concepts in terms of long-term observations.     

Promotion of autonomy for participation in physical activity: a study based on the trans-contextual model of motivation

The aim of this study was to analyse the effects of a school-based intervention to promote physical activity, utilising the postulates of the trans-contextual model of motivation. The study examined two separate classes of elementary school students (mean age 11.28?years), one of which served as the control group (n?=?26) and the other as the experimental group (n?=?21). The intervention in the experimental group consisted of showing videos related to physical activity participation, conducting discussions and doing tasks related to the content presented in the videos and conducting family discussions. Autonomy support from teachers, peers and parents; motivation in physical education and leisure time physical activity; the different variables of theory of planned behaviour; and physical activity, were measured before and after the intervention. Results showed an increase in teacher autonomy support, identified regulation in physical education, autonomy support from parents and peers, integrated and identified regulation in leisure time physical activity, control, subjective norm, intention and physical activity in the experimental group. Furthermore, this increase resulted in post-intervention differences across groups in such variables. Results are discussed in relation to the important role of families in the promotion of physical activity participation.     

Effects of combination of irbesartan and perindopril on calcineurin expression and sarcoplasmic reticulum Ca2＋-ATPase activity in rat cardiac pressure-overload hypertrophy

INTRODUCTION Left ventricular hypertrophy has been thought to be the principal predicators of predisposing risk factor of cardiac morbidity and mortality (Devereux, 1995; Levy et al., 1990). The pathogenesis that mediates cardiac hypertrophy is poorly understood. Cardiachypertrophy can be induced by hemodynamic over-load, ischemic disease, neurohumoral factors and intrinsic defects in cardiac structural protein genes (Sadoshima and Izumo, 1997; Vikstrom and Lein-wand, 1996). Another in…     

The role of autonomy supportive activities on students’ motivation and beliefs toward out-of-school activities

Physical education in elementary education usually provides children’s first contact with sports. According to the trans-contextual model of motivation, physical education teachers can positively influence children’s beliefs toward and actual leisure time physical activity behavior. The aim of this study was to examine the effect of a dance-based physical education program on motivation regarding physical education lesson participation, as well as leisure time physical activity participation. The sample consisted of 252 pupils attending Grades 5 and 6 of elementary school (M_age?=?10.48 years, SD?=?0.50 years). Participants were randomly assigned into three groups. The first group attended a physical education lesson based on various forms of dance, the second one attended lessons with Greek traditional dances only, and the third group served as active control group that attended the typical curriculum. The intervention lasted six weeks. Before and after the intervention, students completed survey-based measures of motivational climate, motivational regulations in physical education and leisure time, enjoyment, attitudes, perceived behavioral control, subjective norms, and intentions toward leisure time physical activity. In support of the trans-contextual model, results showed that students in the dance intervention programs scored significantly higher in perceptions of motivational climate and beliefs toward leisure time physical activity. The findings of the study suggest that dancing lessons at school can bolster more positive attitudes and beliefs toward physical education and leisure time physical activity.     

Effects of Practical Life Materials on Kindergartners' Fine Motor Skills

A pretest-posttest control group design was used to measure the effect of practical life materials on public school kindergarten children's fine motor skill development over a 6-month period. The dependent measure was a penny posting test. More than 50 different sets of activities were provided to the experimental group (n = 101). Teachers coached students in following specific steps to use tweezers, tongs, and spoons to manipulate a variety of objects. Students then employed the materials during center time in their classrooms. Although experimental and control group teachers reported equal amounts of fine motor activity in their classrooms, significant interaction effects were found indicating the experimental group outperformed the control on the posttest measure. An overall effect size of 0.74 indicates that the type of fine motor activity is important in children's development.     

Intrathymic inoculation of donor liver specific antigen alleviates rejection of liver allotransplantation

Use and effects of liver specific antigen in orthotopic liver transplantations were researched in this study. Group I: syngeneic control (Wistar-to-Wistar); Group II: acute rejection (SD-to-Wistar); Group III: Thymic inoculation of SD rat LSA day 7 before transplantation. The observation of common situation and survival time, rejection grades, NF-κB activity of splenocytes and IL-2mRNA expression of grafted liver were used to analyze acute rejection severity and immune state of animals in different groups. The common situation of group I was very well after transplantation and no signs of rejection were found. Recipients of group II lost body weight progressively All dead within day 9 to day 13 posttransplantation; median survival time was 10.7 ±0.51 days. It was an optimal acute rejection control. As for group III, 5 out of 6 recipients survived for a long time and common situation was remarkably better than that of group II. Its rejection grades were significantly lower than that of group II(P<0.05). NF-κB activity was only detected in group I at day 5 and day 7 after transplantation, whereas high activity of NF-κB was detected at all time points in groupII and the low NF-κB activity detected in group III was significantly lower than that of group II (P<0.05). No IL-2mRNA expression was detected at any time point in group I, whereas high level expression was detected at all time points in group II and the low level expression only detected at day 3 in group III was significantly lower than that of group II (P<0.05). Conclusion: LSA is an important transplantation antigen which is involved directly in the immunorejection of liver transplantation. We report here for the first time that intrathymic inoculation of LSA can alleviate the rejection of liver allotransplantation; and that grafts can survive for a long time thereby, thus leading to a novel way to achieve liver transplantation immunotolerance.

The professional development needs of staff in Wales on behaviour management and attendance: findings from the NBAR Report

This paper presents the evidence collected for the National Behaviour and Attendance Review (NBAR) in Wales on the professional development needs of staff on behaviour management and school attendance. These data were collected in two stages between 2006 and 2008. At Stage 1, data were collected from four pre‐selected professional focus groups who met throughout Wales to consider specific topics relating to the behaviour of children and young people in schools at the present time (n = 121). At Stage 2, relevant professional focus groups were established to specifically examine the themes of professional development and training in behaviour management and attendance in both North and South Wales (n = 62). This latter group activity built on the preliminary work of the NBAR review group’s own sub‐group on professional development and training. The paper considers the outcome of all these findings and their implications for future practice in Wales.     

A school-based motivational intervention to promote physical activity from a self-determination theory perspective

The authors analyzed the effects of a multidimensional intervention to promote physical activity (PA) in school, based on self-determination theory. The study involved 88 students, between 14 and 17 years old, who were divided into a control group (n = 59) and an experimental group (n = 29). In the experimental group, a 6-month intervention was conducted, applying a teaching unit of fitness and health in physical education (PE) classes, an extracurricular program of healthy PA, and meetings with families. Questionnaires were administered to measure different motivational variables and PA levels at four time points. Significant differences were found in favor of the experimental group in parental and peer autonomy support; integrated regulation in PE; autonomy, intrinsic, and identified regulation in leisure-time PA; moderate, hard, and very hard PA; and physical self-worth. Motivational effects were maintained over time but the effects on PA levels disappeared at 6 months.     

Child Engagement in Inclusive Preschools: Contributions of Classroom Quality and Activity Setting

Preschool process quality and activity setting are considered important aspects influencing child engagement. As such, it is important to understand how educational settings can promote engagement, particularly for children with disabilities and/or at risk. This observational study describes process quality and activity setting in inclusive preschools, analyzing its predictive role for child engagement. Participants were 184 children attending 39 preschools. Three groups of children, nested within classrooms, were considered: with disabilities (n = 45), at risk (n = 59), typically developing (n = 80). Child Observation in Preschool assessed engagement and activity setting; Classroom Assessment Scoring System assessed quality of teacher–child interactions. Research Findings: Results from multilevel regressions show that classroom emotional support and organization and more time in free play were positively predicting child engagement, whereas more time in whole group was a negative predictor of engagement. Besides these main effects, an interaction effect between child developmental functioning and activity settings was found. For at-risk children, more time in whole-group activities had greater negative effects on child engagement. For children with disabilities, more time in free-play had greater positive effects on child engagement. Practice or Policy: Results contribute to inform teachers regarding the importance of individualizing interactions and planning activity settings to promote engagement and participation in inclusive preschools.     

Evaluating the effectiveness of a mindfulness coloring activity for test anxiety in children

The authors investigated the effectiveness of a mindfulness art activity compared with a free draw/coloring activity on test anxiety in children. The sample consisted of 152 students (50% female; M_age = 10.38 years, SD = 0.88 years) randomly assigned to a mindful (n = 76) or free (n = 76) group. Participants completed a standardized measure of anxiety and state mindfulness before and after the coloring activity, immediately before a spelling test, as well as a measure of dispositional mindfulness. Results revealed an overall significant decrease in test anxiety and an overall significant increase in state mindfulness following the interventions. Furthermore, although a significant negative correlation was found between dispositional mindfulness and change in state mindfulness pre- and post-coloring intervention, a significant positive correlation was found between dispositional mindfulness and pre-intervention state mindfulness, suggesting a possible ceiling effect. Explanations for these findings and implications for school personnel and future research are discussed.     

Cognitive Motor Coordination Training Improves Mental Rotation Performance in Primary School‐Aged Children

The long‐term physical activity in specific sport activities can change the quality of mental rotation performance. This study investigates the influence of Life Kinetik—a motion program with tasks of cognition and motor coordination—on mental rotation performance of 44 primary school–aged children. While the experimental group received Life Kinetik lessons twice a week for 5 weeks, the control group took part in regular physical education classes for the same period of time. Both groups performed a mental rotation task before and after the intervention. The experimental group showed a significant increase in mental rotation ability than the control group.     

Synthesis of Schiff bases of naphtha[1,2-d]thiazol-2-amine and metal complexes of 2-（2＇-hydroxy）benzylideneaminonaphthothiazole as potential antimicrobial agents

Objective： A series of 2-benzylideneaminonaphthothiazoles were designed and synthesized incorporating the lipophilic naphthalene ring to render them more capable of penetrating various biomembranes. Methods： Schiff bases were synthesized by the reaction of naphtha[1,2-d]thiazol-2-amine with various substituted aromatic aldehydes. 2-（2＇-Hydroxy）ben- zylideneaminonaphthothiazole was converted to its Co（Ⅱ）, Ni（Ⅱ） and Cu（Ⅱ） metal complexes upon treatment with metal salts in ethanol. All the compounds were evaluated for their antibacterial activities by paper disc diffusion method with Gram positive Staphylococcus aureus and Staphylococcus epidermidis and Gram negative Escherichia coli and Pseudomonas aeruginosa bacteria. The minimum inhibitory concentrations of all the Schiff bases and metal complexes were determined by agar streak dilution method. Results： All the compounds moderately inhibited the growth of Cram positive and Gram negative bacteria. In the present study among all Schiff bases 2-（2＇-hydroxy）benzylideneaminonaphthothiazole showed maximum inhibitory activity and among metal complexes Cu（Ⅱ） metal complex was found to be most potent. Conclusion： The results obtained validate the hypothesis that Schiff bases having substitution with halogens, hydroxyl group and nitro group at phenyl ring are required for the antibacterial activity while methoxy group at different positions in the aromatic ring has minimal role in the inhibitory activity. The results also indicated that the metal complexes are better antibacterial agents as compared to the Schiff bases.     

The Effect of Passive and Active Education Methods Applied in Repetition Activities on the Retention of Anatomical Knowledge

This study examines the long-term retention of anatomical knowledge from 180 students after various repetition activities. The retention of anatomical knowledge was assessed by multiple-choice tests at five different points in time: before and after a course in Functional Anatomy, before and after repetition activities that occurred 14 weeks after this course, and 28 weeks after this course to establish long-term retention. Students were divided into five groups: one without any repetition activity, one with a restricted repetition activity (the multiple-choice test), and three groups that were offered repetition activities (traditional lecture, e-learning module, and small group work in the dissection room). During all three repetition activities the same information was conveyed, and this content was not revisited in other courses for the duration of the study. The results showed that students who did not engage in a repetition activity scored significantly lower on the long-term retention test compared to all other groups (ANCOVA: P = 0.0001). Pair-wise comparison with estimated means showed that the other four groups, regardless of the type of repeating activity, did not differ in the amount of knowledge they retained during any of the five assessments (P = 0.008, P = 0.0001, P = 0.001, and P = 0.0001, respectively). This study suggests that the type of repetition activity has no effect on knowledge retention both immediately following the activity and in the long term. It is concluded that the repetition of anatomical knowledge in any form is beneficial for students and will likely improve student outcomes in a curriculum that builds on prior knowledge.     

The effects of college students’ positive thinking,learning motivation and self-regulation through a self-reflection intervention in Taiwan

This quasi-experimental study examined the effects of a self-reflection intervention on college (college in this article refers to university-level education) students’ positive thinking, learning motivation and self-regulation in Taiwan. One hundred and two college students were selected to participate in an 18-week intervention forming the experimental group (EG) which emphasized providing main lecture, role-play, self-reflection activity, group discussion and group work. Another 179 college students from two other courses were selected as a comparison group. This study showed that supportive, resourced discussion with peers and instructor, self-reflection activities and assignment as a facilitative agent improved the EG students’ positive thinking, learning motivation and self-regulation. In addition, three structural equation models revealed that positive thinking had a strong and direct relation to Taiwanese college students’ pretest learning motivation (β?=?.85) and self-regulation (β?=?.77); learning motivation had a strong and direct relation to students’ pretest positive thinking (β?=?.86) and self-regulation (β?=?.81); and self-regulation had a strong and direct relation to students’ pretest positive thinking (β?=?.83) and learning motivation (β?=?.86). Instructional implications and research recommendations are discussed.     

Process reflection during Japanese lesson study experiences by prospective secondary mathematics teachers

Although potentially powerful for educators, the construct of teacher reflection has become diluted, rendering teacher engagement with meaningful reflection problematic. This article presents a theoretical framework that divides teacher reflection into two broad categories. The first and most common incident reflection occurs as specific incidents or episodes unconnected to future activity. The second process reflection—based on the work of John Dewey and Donald Sch?n—connects reflective incidents into a cyclic progression that refines ideas through experimental action. I examined the reflective activity of a group of prospective secondary mathematics teachers as they jointly planned a public school lesson to illustrate how incidents of reflection can be refined and linked into more powerful and purposeful progressions of ideas. I conclude with implications for mathematics teacher development.     

Better Movers and Thinkers: An evaluation of how a novel approach to teaching physical education can impact children's physical activity,coordination and cognition

This study aimed to identify what impact a novel approach to teaching physical education (PE) had on children's physical activity (PA), coordination and cognition compared to current provision. One hundred and fifty children were recruited from six primary schools in Scotland. Outcome measures were the Cognitive Assessment System, the Physical Activity Habits Questionnaire for Children and fundamental locomotor skills (crawling, creeping, marching and skipping). Pre-, post- and 6-month follow-up testing was conducted and data analysed comparing a control and an intervention group. Each group received 2 hours of PE each week during the 16-week intervention. Current provision in PE was delivered in the control group and a Better Movers and Thinkers approach to PE delivered in the intervention group. Significant effects of intervention relative to the control group were identified in cognition (p ≤ 0.001, d = 0.76) and coordination (p ≤ 0.001, d = 0.97). No significant effects of intervention were identified for PA (p ≤ 0.200, d = 0.24). The improvement in the outcome measures remained at the 6-month follow-up testing. The present study has identified cognitive and coordination improvements as a result of a novel PE intervention with benefits maintained 6 months later. This supports the need for modification in current PE provision to optimise the potential for learning across the curriculum.     

Using a 10-day mindfulness-based app intervention to reduce burnout in special educators

The field of special education is thought to be a stressful profession due to the complex needs of the students. The current study aimed to assess the effectiveness of a mindfulness-based smartphone application intervention for reducing burnout in special educators. We used the Copenhagen Burnout Inventory scale (with three subscales; personal, work-related and student-related) to measure burnout and the Five Facets of Mindfulness (shortened version) to assess mindfulness. Special educators (n = 29) were assigned to either the experimental group (n = 14) which used the ‘Smiling Mind’ app for guided meditations or the active control group (n = 15) which used ‘Day One’, a note-taking app, for a list-making activity. Both groups used their assigned apps for 10 days. The experimental group showed significant reductions from baseline to post-intervention on the personal burnout subscale while the control group did not, indicating that the intervention affected this domain of burnout. This was maintained at a 2-week follow-up. Mindfulness scores did not significantly increase in the experimental condition, meaning that the mechanism of this decrease in personal burnout is unknown. Further research is needed in order to add to the knowledge on preventing and treating burnout in special educators.
