Outside school time: an examination of science achievement and non-cognitive characteristics of 15-year olds in several countries

Elementary and secondary students spend more hours outside of class than in formal school and thus have more time for interaction with everyday science. However, evidence from a large international survey, Program of International Student Assessment (PISA) (OECD 2012), found a negative relationship between number of hours attending after-school science and science assessment scores in many countries, raising questions about why. The secondary analysis of the 2006, 2009, and 2012 PISA surveys found that in most Western countries the longer students attended after-school science programs (in a typical week), the lower their PISA standardized science test score, but the higher their positive attitudes toward future science careers, interest in science, and self-confidence in science. Several potential hypotheses for this relationship are examined and rejected. Further analysis of a causal relationship between frequent attendance in after-school programs and student achievement and attitudes should clearly identify the content of the program so that the analysis could distinguish experiences closely related to regular school curricula from the informal science activities that are not. A new analysis also should include carefully designed longitudinal surveys to test the effectiveness of informal experiences on later life choices in career and study.     

Nonscience majors learning science: A theoretical model of motivation

A theoretical model of nonscience majors' motivation to learn science was tested by surveying 369 students in a large‐enrollment college science course that satisfies a core curriculum requirement. Based on a social‐cognitive framework, motivation to learn science was conceptualized as having both cognitive and affective influences that foster science achievement. Structural equation modeling was used to examine the hypothesized relationships among the variables. The students' motivation, as measured by the Science Motivation Questionnaire (SMQ), had a strong direct influence on their achievement, as measured by their science grade point average. The students' motivation was influenced by their belief in the relevance of science to their careers. This belief was slightly stronger in women than men. Essays by the students and interviews with them provided insight into their motivation. The model suggests that instructors should strategically connect science concepts to the careers of nonscience majors through such means as case studies to increase motivation and achievement. © 2006 Wiley Periodicals, Inc.

齐国兵学文化与《孙子兵法》

齐国大地军事家辈出,兵法著作内容宏富,孙武生长于泱泱大国的古老齐国,齐国是中国的兵学发源地,先秦的主要兵书出自齐地,孙武的兵学思想上承源远流长的齐国兵学传统流脉,深深承受于地域文明滋养,深深打上了齐文化的印痕。在中国兵学发展历史上,从姜尚到孙武再到其后的孙膑,形成了源远流长而又一脉相承的齐国兵学文化传统。     

长沙市初中生当前学习动机特点调查

通过采用问卷法对长沙市初中生的学习动机状况进行了调查研究。结果表明：（1）初中生的学习动机中，表面型、深层型与成就型三种动机并存，其中，以成就型和深层型学习动机为主，表现型学习动机居后；（2）初中生在三种学习动机上性别差异不显著，在成就型学习动机上有显著的年级效应；（3）初中优、差生在三种学习动机上均表现出一定的差异，且在成就型动机上达到了极显著的水平。     

美国非虚构小说崛起的科技和思想背景

美国非虚构小说在上世纪中期的繁荣具有深厚的科学技术和思想意识根源。科技创新在提升人类认识水平和改善生存环境的同时，也革新了作家的认知观念和创作思想。认识危机的弥漫，怀疑意识的扩散，使作家放弃了虚构、解释和说教的传统，代之以真实事件来表达主题。而对这一段历史的回顾具有双重意义：不但可加深对美国这一重要的学现象的研究，而且给我们提供了洋为中用，以史为鉴的依据，有助于我们探讨国内目前纪实性学的繁荣。

Characteristics of students who benefit from high-quality mathematics instruction

The present study examined characteristics of students who took advantage of the opportunity to learn Algebra II from a highly skilled teacher. In particular, student information was gathered concerning: (a) the amount of mathematics students knew prior to the class, (b) their motivation for learning mathematics, (c) the number and types of interactions they had with the teacher during class, (d) degree of self-regulation, and (e) general aptitude. A model for achievement was used that suggests both opportunity and propensity are important (i.e., students must be willing and able to take advantage of opportunity). Support for the model was found. Propensity to take advantage of a highly favorable opportunity accounted for almost sixty percent of the variance in achievement. In particular, students who were self-regulated, had strong mathematics backgrounds, and had low levels of frustration benefited more from high-quality instruction.
