Analysis of STEM Activities in Primary Students’ Science Projects in an Informal Learning Environment

This study adopted a researcher-generated framework to analyze STEM activities demonstrated in primary students’ science projects in an annual extracurricular event held in Hong Kong. Ten students’ project reports were randomly selected from each of the three groups of 24 outstanding, 45 merit, and 68 consolation awarded projects. Content analysis was conducted to code the activities in each project. The coded information was then changed into numerical data for quantitative analysis. The results showed that, in general, more engineering and science activities than technology and mathematics activities were adopted by the primary students in their projects. More projects with the Outstanding Award conducted STEM activities than those projects with Merit and Consolation Awards, and significant group differences existed in the science and mathematics activities. Besides, science activities significantly positively related to engineering and mathematics activities. Furthermore, STEM-related content knowledge of discipline core ideas and crosscutting concepts were reported. This study sheds light on the pattern of STEM activities in students’ science projects, and has implications for promoting STEM integration in primary education.     

The counseling needs of foreign students

This paper reports the findings of three studies of the counseling needs of international students at a medium sized University in the Midwestern region of USA. The studies were conducted over a period of five years (1977–83), and provide an historical perspective on the changes in student needs as well as in the programs designed to respond to these needs.     

Creative literacy activities promote positive reading attitude in children learning English as a foreign language

This study investigated the effects of creative literacy classroom activities on the acquisition of English as a foreign language. Ninety Chinese second graders were tested on reading attitude and English receptive vocabulary knowledge. They were randomly assigned to either a control group or an experimental group, which engaged in English creative classroom activities for 10 weeks. Repeated measures analyses showed a significant interaction effect for reading attitude, providing empirical evidence that English creative classroom activities can enhance reading attitude. This study extends past research by demonstrating the links between creative activities and reading attitude, as well as highlights the feasibility of incorporating creative literacy activities within foreign language education. This provides a new direction for researchers and educators to develop instructional practices that incorporate a stimulating environment for English‐as‐a‐foreign‐language students. Future longitudinal research could examine whether these benefits can be maintained over a longer period.     

Lumbar spinal loads and muscle activity during a golf swing

This study estimated the lumbar spinal loads at the L4-L5 level and evaluated electromyographic (EMG) activity of right and left rectus abdominis, external and internal obliques, erector spinae, and latissimus dorsi muscles during a golf swing. Four super VHS camcorders and two force plates were used to obtain three-dimensional (3D) kinematics and kinetics of golf swings performed by five male collegiate golfers. Average EMG levels for different phases of golf swing were determined. An EMG-assisted optimization model was applied to compute the contact forces acting on the L4-L5. The results revealed a mean peak compressive load of over six times the body weight (BW) during the downswing and mean peak anterior and medial shear loads approaching 1.6 and 0.6 BW during the follow-through phases. The peak compressive load estimated in this study was high, but less than the corresponding value (over 8 BW) reported by a previous study. Average EMG levels of different muscles were the highest in the acceleration and follow-through phases, suggesting a likely link between co-contractions of paraspinal muscles and lumbar spinal loads.     

Ground reaction forces and kinematics of plant leg position during instep kicking in male and female collegiate soccer players

The players' ability to achieve the greatest distance in kicking is determined by their efficiency in transferring kinetic energy from the body to the ball. The purpose of this study was to compare the kinetics and kinematics of the plant leg position between male and female collegiate soccer players during instep kicking. Twenty-three soccer players (11 males and 12 females) were filmed in both the sagittal and posterior views while performing a maximal instep kick. Plant leg kinetic data were also collected using an AMTI 1000 force platform. There were no significant differences between the sexes in plant leg position, but females had significantly greater trunk lean, plant leg angle, and medial-lateral ground reaction force than the males. Males showed higher vertical ground reaction forces at ball contact, but there were no significant differences in ball speed at take-off between the sexes. Ball speed at take-off was inversely related to peak anterior-posterior ground reaction force (-0.65). The anatomical differences between the sexes were reflected in greater trunk lean and lower leg angle in the females.
