Psychosocial factors impacting STEM career selection

Attention on P-20 science, technology, engineering, and mathematics (STEM) education has increased tremendously in recent years. Many efforts are underway to promote STEM major and career selection across the nation; specifically, in engineering and computer science. The authors' purpose was to examine an underlying profile combinations of latent traits that influence student STEM career selection while designing serious educational games (SEGs). The authors combine a number of quantitative analysis methods in an effort to develop a rich understanding of how a profile combination of traits interact with one another to effect selection of STEM careers and majors. Study participants were 585 students enrolled in a full-time traditional high school. The addition of SEG design experiences into the student profile increases the probability of STEM career selection by 5.1 times.     

科学发展观与基础教育课程改革--对课程改革的理性反思

新课程改革存在理论准备不足、实践先导不充分、新课程与旧课程缺乏衔接、师资条件不匹配、社会接纳程度不够等问题.新课程改革对科学发展观的偏离,可能给教育的可持续发展造成潜在性危机.     

尚奇:汉赋创作的潜在动力

尚奇是汉赋创作实践所呈现出的一种审美流向。西汉赋尚奇物之铺陈，多带有诡奇之气；东汉赋之尚奇则表现为题材的尚奇入怪。汉赋尚奇与汉文化受楚文化的影响有关，也与汉人尚奇谈的风尚有关，更与汉人对辞赋娱人性质的认识和汉赋作家文学创作上的超越心理有关。尚奇是汉赋创作的潜在动力。     

《"锻炼锻炼"》潜文本释义——关于赵树理评价问题

<锻炼锻炼>是一个充满紧张的复杂文本.它的潜文本意义与其表层的意识形态形成有力的对峙,显示了在新的研究视野下赵树理小说丰富的阐释可能性.然而这种潜文本并不是赵树理有意识的创造而是潜意识的产物.它提示不能根据十七年的文学环境对赵树理做简单的评价.     

旅游规划评审中的"潜规则"质疑

旅游规划评审时甲方、乙方与评委会三方“博弈”,派生出一系列“不足为外人道”的潜规则。围绕甲方追求质量抑或形式、评委追求真理抑或情面、乙方追求声誉抑或利益的“位移”,潜规则贯穿于评审前的评委遴选、评审本设计与装潢及交付时间控制,评审中的表决、拟写评语、归纳修改意见,评审后的修改本鉴定等诸多环节。《旅游规划通则》实有修订完善之必要。     

Relationships among Singaporean secondary teachers’ conceptions of assessment and school and policy contextual factors

This study examines teachers’ conceptions of assessment and related contextual factors at the classroom, school and national levels. A representative survey of Singaporean secondary school teachers resulted in a final sample consisting of 229 teachers from 9 secondary schools. Findings on that, teachers endorse views of assessment for school accountability, student accountability and student improvement, but little endorsement of assessment as irrelevance. Teachers report feeling capable and qualified to use assessments, but concerned about how much they are trusted as assessors at school and national levels. Follow-up latent class analysis identified groups of teachers based on their responses to the irrelevance of assessment; teachers who found assessment irrelevant were present across all schools and subjects, but showed lower sense of preparation for assessment, school-level support and importance of academic success in society.     

Robustness of Stepwise Latent Class Modeling With Continuous Distal Outcomes

Recently, several bias-adjusted stepwise approaches to latent class modeling with continuous distal outcomes have been proposed in the literature and implemented in generally available software for latent class analysis. In this article, we investigate the robustness of these methods to violations of underlying model assumptions by means of a simulation study. Although each of the 4 investigated methods yields unbiased estimates of the class-specific means of distal outcomes when the underlying assumptions hold, 3 of the methods could fail to different degrees when assumptions are violated. Based on our study, we provide recommendations on which method to use under what circumstances. The differences between the various stepwise latent class approaches are illustrated by means of a real data application on outcomes related to recidivism for clusters of juvenile offenders.     

现代化中的传统文化与构建社会主义和谐社会

现代化是现代性成长中从传统社会向现代社会转型的过程。它不是传统文化的断裂,而是必须发挥传统文化的现代潜能。构建社会主义和谐社会,是在社会变革中以马克思主义为指导,弘扬传统文化中公平正义、诚信友爱、自强不息、中庸和合、"天人合一"的精神,克服现代性分裂导致的矛盾冲突,走出有中国特色的社会主义现代化道路。     

Structural Models for Binary Repeated Measures: Linking Modern Longitudinal Structural Equation Models to Conventional Categorical Data Analysis for Matched Pairs

The current widespread availability of software packages with estimation features for testing structural equation models with binary indicators makes it possible to investigate many hypotheses about differences in proportions over time that are typically only tested with conventional categorical data analyses for matched pairs or repeated measures, such as McNemar’s chi-square. The connection between these conventional tests and simple longitudinal structural equation models is described. The equivalence of several conventional analyses and structural equation models reveals some foundational concepts underlying common longitudinal modeling strategies and brings to light a number of possible modeling extensions that will allow investigators to pursue more complex research questions involving multiple repeated proportion contrasts, mixed between-subjects × within-subjects interactions, and comparisons of estimated membership proportions using latent class factors with multiple indicators. Several models are illustrated, and the implications for using structural equation models for comparing binary repeated measures or matched pairs are discussed.
