Cross‐level invariance in a multilevel item response model can be investigated by testing whether the within‐level item discriminations are equal to the between‐level item discriminations. Testing the cross‐level invariance assumption is important to understand constructs in multilevel data. However, in most multilevel item response model applications, the cross‐level invariance is assumed without testing of the cross‐level invariance assumption. In this study, the detection methods of differential item discrimination (DID) over levels and the consequences of ignoring DID are illustrated and discussed with the use of multilevel item response models. Simulation results showed that the likelihood ratio test (LRT) performed well in detecting global DID at the test level when some portion of the items exhibited DID. At the item level, the Akaike information criterion (AIC), the sample‐size adjusted Bayesian information criterion (saBIC), LRT, and Wald test showed a satisfactory rejection rate (>.8) when some portion of the items exhibited DID and the items had lower intraclass correlations (or higher DID magnitudes). When DID was ignored, the accuracy of the item discrimination estimates and standard errors was mainly problematic. Implications of the findings and limitations are discussed. 相似文献

The concept of emotional affinity and connection with nature using the term of ‘biophilia’ along with its counter-part ‘biophobia’ has been merely researched in the area of environmental education. In this study, it was hypothesized that children’s negative emotions (biophobia) such as fear towards insects can be changed into affinity (biophilia) through an environmental education program. One hundred and four third-grade students from an elementary school in Seoul, South Korea participated in the honey bee environmental education program, and their emotional changes were measured with Inclusion of Nature in Self and Connectedness to Nature Scale. The result after the program implementation showed that the participants’ affinity toward nature was significantly improved. This empirical study suggests that an environmental education programs on insects of which children initially feel scared can be effective in helping to overcome fear toward insects and nature, and to revive their innate biophilia. Especially, honey bees, one of the most crucial insect species providing priceless ecosystem services can be a good medium for environmental education program to promote children’s innate love towards nature. This study, to the authors’ knowledge, was the first research which attempted to link an insect-mediated environmental education program to children’s connectedness to nature with the biophilia–biophobia approach. 相似文献

This research explicates the construct of social ability and describes the relationship between students' academic motivation and social ability in online learning environments. Findings reveal perceived peers social presence, perceived written communication skills, perceived instructor social presence, comfort with sharing personal information, and social navigation as the five factors that define social ability. In addition, the multivariate multiple regression analyses indicate that different motivational constructs vary in their relationships with the multiple social ability factors. Intrinsic goal orientation is related to perceived peers social presence. Self-efficacy explains the variance of perceived instructor social presence and comfort with sharing personal information. Task value is associated with social navigation and both perceived peers and instructor social presence. Additional studies are needed to replicate the current findings and further explicate social ability in online learning, to continue to improve the social ability instrument, and to examine the value of other academic motivation beliefs in predicting social ability as well as that of social ability in predicting learning outcomes. 相似文献

The authors investigate the salient factors that influence users’ continuance intentions to use smart-connected sports products. Drawing on the theory of planned behavior (TPB), they propose that three major factors—attitude, social comparison as social influence, and perceived behavioral control—significantly influence users’ continuance intentions. Smart-connected sports product users (N = 236) participated in this study. Collected data were analyzed using Partial Least Squares (PLS) modeling. Results suggest two different attitudinal beliefs—technology-related (perceived usefulness) and fashion-related (perceived comfort) factors—of smart-connected sports products influence attitudes toward the products and that control-related factors (technical functionality and facilitating conditions) play a role in regulating users’ volitional behaviors from their intentions. The authors highlight user beliefs of smart-connected sports products based on TPB and propose a concrete, practical set of factors that practitioners might manipulate to facilitate users’ continuance intentions to use smart-connected sports products. 相似文献

In this era of globalization, cross-cultural comparison studies could help counselor training programs enhance educational opportunities that are informative, supportive, and culturally responsive to students. Counselors-in-training in both the United States and South Korea were sampled in this study assessing self-esteem (individual and collective) and counselor activity self-efficacy (CA self-efficacy). Results indicated that American students endorsed higher levels of collective self-esteem and CA self-efficacy compared to Korean students. Age was positively correlated with CA self-efficacy in both the American and Korean samples. Additionally, the variable of supervision hours and internship experience was positively correlated with CA self-efficacy for American students, but showed no relationship with CA self-efficacy for Korea students. Implications for understanding the cultural differences of counseling-trainees’ self-confidence and the need for conducting cross-cultural comparison studies to provide insights about the training and development of trainees in cross-cultural settings are discussed. 相似文献

This longitudinal study described park usage and assessed the contribution of parks to moderate to vigorous physical activity (MVPA) among adolescent girls. High school girls from California (n = 131) and Minnesota (n = 134) wore a global positioning system (GPS) monitor and accelerometer for 6 consecutive days at two time points, one year apart. Park visits were classified by linking the GPS, accelerometer, and park and built environment data around home and school locations into a geographic information system. At baseline, 20% of girls visited a park at least once (mean 0.1 times/day), which was similar one year later (19%, mean 0.1 times/day). Girls lived a mean Euclidean distance of 0.2 miles to the nearest park at both times. Among all park visits, the mean Euclidean distance of the park visited was 4.1 (baseline) and 3.9 miles (follow-up). The average duration of park visits was higher at baseline (63.9 minutes) compared to follow-up (38.4 minutes). On days when a park was visited, MVPA was higher than on days when a park was not visited. On average, 1.9% (baseline) and 2.8% (follow-up) of MVPA occurred in parks. In this study, parks were an under-used resource for adolescent girls, particularly for MVPA. 相似文献

This paper describes portfolio development by pre-service art teachers in a secondary teaching programme at California State University, Los Angeles, USA. A portfolio reflects knowledge, skills, and beliefs about teaching in general and teaching art specifically. It displays one’s learning experiences as they are collected, organized, and refined to provide a critical framework and rich portrayal of one’s best work. The article addresses the questions of what a portfolio in art education is, what its goals are, how one creates a portfolio, how one assesses portfolios once they are developed, what the issues and challenges surrounding the use of portfolios as assessment tools are, and finally, some likely future developments of portfolio assessment in teacher education. 相似文献

The purpose of the study is to analyse how the standard of resting metabolic rate (RMR) affects estimation of the metabolic equivalent of task (MET) using an accelerometer. In order to investigate the effect on estimation according to intensity of activity, comparisons were conducted between the 3.5 ml O2 · kg?1 · min?1 and individually measured resting VO2 as the standard of 1 MET. MET was estimated by linear regression equations that were derived through five-fold cross-validation using 2 types of MET values and accelerations; the accuracy of estimation was analysed through cross-validation, Bland and Altman plot, and one-way ANOVA test. There were no significant differences in the RMS error after cross-validation. However, the individual RMR-based estimations had as many as 0.5 METs of mean difference in modified Bland and Altman plots than RMR of 3.5 ml O2 · kg?1 · min?1. Finally, the results of an ANOVA test indicated that the individual RMR-based estimations had less significant differences between the reference and estimated values at each intensity of activity. In conclusion, the RMR standard is a factor that affects accurate estimation of METs by acceleration; therefore, RMR requires individual specification when it is used for estimation of METs using an accelerometer. 相似文献
