The effects of static stretching on speed and agility: One or multiple repetition protocols?

Although static stretching (SS) is utilized during warm-up before training and competition, the results about its effects on performance remain controversial. We examined whether performing a stretch of short-to-moderate duration (<60 sec) in a single repetition produces a similar or different effect on speed and agility performance from the effect which is produced while performing the same stretch in multiple repetitions of the same total duration. According to a repeated measurement design, 40 trained males were randomly assigned to either (1) a single repetition group or (2) a multiple repetition group. The participants in each group performed five trials: a control trial (no stretches were performed) and four experimental trials of SS protocols consisting of five exercises performed at either 20 sec (2 × 10 in the second group), 30 sec (3 × 10 in the second group), 40 sec (4 × 10 in the second group) or 60 sec (6 × 10 in the second group) of total duration. A two-way repeated measures analysis of variance showed that the participants in both group improved their speed performance in response to the 20-sec trial, whereas agility remained unaffected. Data analysis also revealed that the repetition number did not affect speed and agility performance. These data suggest that SS of short duration (<30 sec) may actually improve acute speed performance, whereas SS of moderate duration may not hamper speed and agility performance. Moreover, the effects of SS protocols are related to the total duration of each exercise and not to the number of repetitions in which each exercise is performed.     

Mathematics-related anxiety and attitudes: examining the impact among Latina preservice teachers

The purpose of this study was to investigate mathematics-related anxiety and attitudes among Latina preservice teachers. Three sections from the Inventory of Mathematics Attitudes, Experience, and Self Awareness were administered to preservice teachers enrolled in a curriculum and instruction mathematics course during the 1st semester of a 2-semester credential program. Pre- and postsurvey data were examined among female students. There were significant differences on 5 statements that suggest positive perceptions about mathematics and 5 statements that suggest negative perceptions about mathematics. We discuss strategies to reduce mathematics anxiety and address attitudes in preservice teachers.

Using the Internet for Communicative Learning Activities in Kindergarten: The Case of the “Shapes Planet”

With the widespread use of the internet, more and more children get acquainted with its various uses at a young age while an increasing number of teachers are designing learning activities that utilize various internet services. Toward this direction, teachers need practical examples of pedagogically verified learning activities. This paper presents an experimental case study of a learning activity meant for teaching preschoolers geometric concepts, which uses communication tools from the internet. The activity constitutes a developmentally appropriate adaptation of a successful model, known as “Monster Exchange”, to kindergarten. The paper presents the proposed adaptation, the experimental findings regarding the errors children mad, the difficulties they encountered, and finally, the drawings that children produced, with the aim of evaluating the appropriateness and the learning value of the activity.     

Single-sex computer classes: An effective alternative

Conclusion Considering the technology gender gap that exists today, there can be no doubt that our current educational system is not engaging female students in technology or awakening them to possibilities of the technology industry as a career. Females are not afraid of computers or lack the ability to master computer skills, but they find the computer environment objectionable (http : / / www.aauw.org/2000/ techsavvybd.html). Several factors within the educational system heighten these objections and impede female progression through technology classes. It is these factors that our educational system must address. Single-sex computer classes offer female students the educational advantages of learning in a comfortable, non-threatening classroom environment where they are encouraged to enthusiastically participate in classroom discussions and activities (Kumagi, 1995). In these classes, curriculum may be adjusted to reflect the need females to see computers as productivity tools (Caplice, 1994). As a result of positive experiences gained while attending single-sex computer classes, females are more likely to pursue higher level computer classes. Although it is possible to argue that single-sex computer classes do not mirror the real world females must contend with once outside the classroom, they are, however, effective interim interventions to enable females to lessen the current technology gap (Kumagi, 1995).     

Education and assessment in Sweden

Education and assessment in Swedish schools have been affected by several reforms during the last two decades. The educational system has moved from centralization to decentralization and a goal‐oriented approach has been introduced on all educational levels. This paper provides an historical overview of the Swedish educational system, educational and assessment policies and principles, to explain why and how the reforms have been carried out. This is followed by a discussion on the effects and consequences of recent reforms, based on findings in recent education and assessment research.     

Conflict, Social Competence, and Gender: Maternal and Peer Contexts

The current study was designed to address two major purposes. The first goal was to investigate the joint influence of children's sociometric status and sex on their conflict behavior, and the second goal was to explore the similarities and differences in children's conflict behavior across two contexts, specifically conflicts arising during interactions with mothers and with peers. Forty-two first-graders were videotaped playing with their mothers and then with an unfamiliar peer partner. Conflict behavior occurring in the mother-child context was quite different from that occurring between children, reflecting the contrast between the vertical and horizontal nature of these relationships. Most striking were the large number of sociometric status and sex differences in conflict behavior found across both contexts. Further, it appears that effective conflict behavior may differ for boys and girls. Implications for future research are discussed.     

Factors influencing the incidence of utilization deficiencies and other patterns of recall/strategy-use relations in a strategic memory task

Factors that influence the incidence of utilization deficiencies and other recall/strategy-use patterns on a strategic memory task were evaluated in two hundred and fourteen 7- and 9-year-old children. Both utilization deficiencies and the incidence of children showing increases in both recall and strategy use over phases were more likely to be observed on phase transitions involving prompting or when different lists of items were included on consecutive trials; in contrast, increases in recall in the absence of increases in strategy use were more likely to be found between trials consisting of the same stimulus items. This research clearly indicates that patterns of recall/strategy-use relations, including utilization deficiencies, vary meaningfully with the age of the child and a variety of contextual factors.     

Resilience to adult psychopathology following childhood maltreatment: evidence from a community sample

OBJECTIVE: Child abuse is an important risk for adult psychiatric morbidity. However, not all maltreated children experience mental health problems as adults. The aims of the present study were to address the extent of resilience to adult psychopathology in a representative community sample, and to explore predictors of a good prognosis. METHODS: Data are drawn from a follow-up of the Isle of Wight study, an epidemiological sample assessed in adolescence and at midlife. Ratings of psychiatric disorder, peer relationships and family functioning were made in adolescence; adult assessments included a lifetime psychiatric history, personality and social functioning assessments, and retrospective reports of childhood sexual and physical abuse. RESULTS: Ten percent of individuals reported repeated or severe physical or sexual abuse in childhood. Prospective measures revealed increased rates of adolescent psychiatric disorders in this group. Rates of adult psychopathology were also high. A substantial minority of abused individuals reported no mental health problems in adult life. Resilience of this kind was related to perceived parental care, adolescent peer relationships, the quality of adult love relationships, and personality style. CONCLUSION: Good quality relationships across childhood, adolescence and adulthood appear especially important for adult psychological well being in the context of childhood abuse.
