Today, early science education is a well-accepted view. Enhancing children’s curiosity about the natural world and fostering positive attitudes toward science are primary goals of science education. However, questions remain regarding the appropriate ways to identify, nurture, and study these emotional states in pre-schoolers. This study examines the potential of using pre-schooler’s verbal (e.g. self-generated figurative expressions) and behavioral (sensorimotor interactions) responses while participating in a scientific activity, as indicators of curiosity and attitudes toward science. The responses of 41 pre-schoolers were documented via a response questionnaire developed for this study. An integrated quantitative–qualitative approach was utilized for data analyses. Results show that pre-schoolers utilize figurative expressions to express various emotional valences. Generation of verbal expressions that entail positive emotional valences and the desire to engage in sensorimotor interactions during a scientific activity were identified as positively correlated. Additionally, girls were more likely to express curiosity and positive attitudes toward science than boys in the context of this study. The findings suggest that these verbal and behavioral measures may serve as indicators of attitudes and curiosity toward science among pre-school children. 相似文献

Two studies were undertaken to assess the value of exposing people to performance visualization in order to help them cope with communication apprehension (CA) in employment interviews. The first study, which took place in a laboratory, employed a pre/post‐test experimental design. Seniors who were preparing to enter the job market took part in mock interviews, completed a state communication apprehension (CA) measure, a trait CA measure, and a scale designed to measure negative thinking. Participants were then assigned to performance visualization, placebo, or control conditions. After exposure to the requisite treatment, they participated in another mock interview and completed the same battery of measures. The second study took place in the field. In this study, participants, who were about to undergo a screening interview for a job, completed state and trait CA measures, were exposed to performance visualization, and completed the state and trait CA measures the second time. These studies indicated that exposure to performance visualization related negatively to CA and negative thoughts, as well as positively to being offered a job. It showed no relationship to being asked back for a second interview. The implications of these findings are discussed in the conclusion of this report. 相似文献

This study explored the relationship between four types of autonomy (health autonomy, informational autonomy, living autonomy, and financial autonomy) and the acceptance of five types of long-term care (adult day care, respite care, assisted living, unit care, and group home) for the elderly in Taiwan. Data were collected from 167 middle-aged and older people. The acceptance of five types of long-term care ranged from 75.9–84.9%. Financial autonomy and information autonomy were significantly related to acceptance of all five types of long-term care. Living autonomy is related to assisted living and group homes. Policy implications are discussed. 相似文献

The emphasis on scientific inquiry has increased the importance in developing the fundamental abilities to conduct scientific investigations and urged a need for valid assessments of students' inquiry abilities. We took advantage of the advanced technology to develop a simulation-based assessment of inquiry abilities (SAIA) that allowed students to generate scientific explanations and demonstrate their experimental abilities. This paper describes the validation of the assessment. Data were collected from 48 12th-grade students at a local high school who were categorized into three groups based on their program majors. Both quantitative and qualitative approaches were utilized to validate SAIA. The quantitative results showed that SAIA was aligned with a validated reasoning-skill test (criterion-related validity), discriminated variance among different groups (construct validity), and was highly suitable for examining inquiry abilities (content validity). Additionally, we utilized the think-aloud technique in order to identify the performances exhibited by students while they accomplished the SAIA tasks. The protocol analysis indicated that in general, students demonstrated the expected abilities in SAIA and that their SAIA scores accurately reflected their performance levels of inquiry abilities. The results suggested that SAIA was a valid assessment for evaluating the inquiry abilities of high school students. This study also provided systemic strategies for validating simulation-based assessments. 相似文献

The purpose of this study was to quantify trunk axial rotation and angular acceleration in pitching and batting of elite baseball players. Healthy professional baseball pitchers (n = 40) and batters (n = 40) were studied. Reflective markers attached to each athlete were tracked at 240 Hz with an eight-camera automated digitizing system. Trunk axial rotation was computed as the angle between the pelvis and the upper trunk in the transverse plane. Trunk angular acceleration was the second derivative of axial rotation. Maximum trunk axial rotation (55 ± 6°) and angular acceleration (11,600 ± 3,100 °/s2) in pitching occurred before ball release, approximately at the instant the front foot landed. Maximum trunk axial rotation (46 ± 9°) and angular acceleration (7,200 ± 2,800 °/s2) in batting occurred in the follow-through after ball contact. Thus, the most demanding instant for the trunk and spine was near front foot contact for pitching and after ball contact for batting. 相似文献

Due to a growing trend of exploring scientific knowledge on the Web, a number of studies have been conducted to highlight
examination of students’ online searching strategies. The investigation of online searching generally employs methods including
a survey, interview, screen-capturing, or transactional logs. The present study firstly intended to utilize a survey, the
Online Information Searching Strategies Inventory (OISSI), to examine users’ searching strategies in terms of control, orientation,
trial and error, problem solving, purposeful thinking, selecting main ideas, and evaluation, which is defined as implicit
strategies. Second, this study conducted screen-capturing to investigate the students’ searching behaviors regarding the number
of keywords, the quantity and depth of Web page exploration, and time attributes, which is defined as explicit strategies.
Ultimately, this study explored the role that these two types of strategies played in predicting the students’ online science
information searching outcomes. A total of 103 Grade 10 students were recruited from a high school in northern Taiwan. Through
Pearson correlation and multiple regression analyses, the results showed that the students’ explicit strategies, particularly
the time attributes proposed in the present study, were more successful than their implicit strategies in predicting their
outcomes of searching science information. The participants who spent more time on detailed reading (explicit strategies)
and had better skills of evaluating Web information (implicit strategies) tended to have superior searching performance. 相似文献

We investigated the effects of different exercise intensities on C-reactive protein (CRP), and whether changes in CRP levels correlated with blood lipid levels. Ten men exercised at 25%, 65%, and 85% of their maximum oxygen consumption rates. Participants' blood was analyzed for CRP and blood lipid levels before and after the exercise sessions. Although there was an intensity effect for postexercise high-density lipoprotein levels, there were no significant differences or correlations for postexercise CRP levels or between CRP and lipid levels across the three exercise intensities. In an acute aerobic bout model with isoenergetic expenditures, CRP was not affected by the exercise intensity. Additionally, changes in blood lipid levels might not have been connected to CIRP levels for physically fit participants. 相似文献
