This paper evaluates the impact of teaching innovations, introduced in public primary schools under the Children Resources International (CRI) Program, on student outcomes. We estimate students’ learning based on their scores on standardized tests. We match schools and children within the treatment and comparison group and find that the CRI Program has been effective in raising learning achievement. Moreover, the results are robust to unobserved selection bias. The average gain for a CRI student represents an improvement of 0.40 standard deviations. The results stay unchanged when we use alternative estimators for the treatment effect including the bias-corrected estimator proposed by Abadie and Imbens (2006). 相似文献

ABSTRACT: One of the core competencies in the IFT education standards for students is to achieve competency in communications skills (that is, oral and written communication, listening, interviewing, and so on). According to the IFT guidelines, by the time students graduate, they should not only be able to search for and condense information but also be able to "communicate technical information to a nontechnical audience." The Education Division of IFT sponsors an annual writing competition for undergraduate students to bring attention to and promote the development of communication skills. The short essays can be on any technical subject or latest development in the food science and technology field that may be important to the consumer. The article must be written in a nontechnical language such that someone reading a local newspaper could also understand it. Due date for submissions is typically the 1st week in June every year. More information on eligibility, rules, submission, and judging criteria is posted on IFT's Student Association website. Monetary prizes are awarded to the authors of the top 3 articles, and the winning entry is published in the Journal of Food Science Education (JFSE) each year. JFSE is pleased to publish this year's winning entry submitted by Masooma Zahed from Chapman Univ. 相似文献

Subject-specific self-efficacy is a measure of confidence in one’s own ability to complete tasks related to that subject. This confidence does not necessarily reflect actual ability in the subject and can be an over- or underestimate of true ability. We use nationally representative samples of 15-year-old students from the US to measure the degree of over-/under-confidence in mathematics and science, and explore its relationship with student demographic characteristics such as gender, grade and race. Our results suggest that white students consistently underestimate their ability, whereas black and Hispanic students consistently overestimate it. This pattern in over-/under-confidence persists even after controlling for student and school level differences. Implications are discussed. 相似文献

Good quality deoxyribonucleic acid (DNA) is the pre-requisite for its downstream applications. The presence of high concentrations of polysaccharides, polyphenols, proteins, and other secondary me- tabolites in mango leaves poses problem in getting good quality DNA fit for polymerase chain reaction (PCR) applications. The problem is exacerbated when DNA is extracted from mature mango leaves. A reliable and modified protocol based on the cetyl- trimethylammonium bromide (CTAB) method for DNA extraction from mature mango leaves is described here. High concentrations of inert salt were used to remove polysaccharides; Polyvinylpyrrolidone (PVP) and β-mercaptoethanol were employed to manage phenolic compounds. Extended chloroform-isoamyl alcohol treatment followed by RNase treatment yielded 950?1050 μg of good quality DNA, free of protein and RNA. The problems of DNA degradation,contamination, and low yield due to irreversible binding of phenolic compounds and coprecipitation of polysaccharides with DNA were avoided by this method. The DNA isolated by the modified method showed good PCR amplification using simple se- quence repeat (SSR) primers. This modified protocol can also be used to extract DNA from other woody plants having similar problems. 相似文献

The present study investigated the role of disciplinary climate in the classroom and student math self-efficacy on math achievement. The student part of the Program for International Student Assessment (PISA) 2003 survey containing 4,199 U.S. observations was employed in a weighted least squares nested multiple regression framework to predict math achievement from disciplinary climate and self-efficacy in addition to several control variables. The results showed that improvement in disciplinary climate was associated with a reduction in the achievement gap whereas improvement in self-efficacy was associated with an expansion in that gap. These effects varied across race and gender. A significant interaction effect was found between the disciplinary climate and self-efficacy. Educational implications are discussed. 相似文献

Research shows that mindfulness interventions for test anxiety in a college student population are beneficial (Lothes, Matney, & Naseer, 2022). This study assessed the effects of online mindfulness practices over a 5-week period on anxiety and test anxiety in college students. Participants included 20 students that were randomly assigned to either a sitting meditation or a wait list control (WLC). A weekly schedule of mindfulness practices was given to participants to complete on their own for 5 weeks. The WLC did not do any mindfulness for the first 5 weeks. Participants in the both conditions showed significant within-group reductions in test anxiety, overall anxiety, and DASS scores during their mindfulness interventions. Both groups also showed significant increases in FFMQ scores. Mindfulness may play a role in the reduction of anxiety and test anxiety. Further research is needed to assess how mindfulness may affect anxiety and test anxiety in college students. 相似文献

A subject analysis of 5195 publications in library and information science (LIS) research in Pakistan over a period of 62 years revealed that the majority of Pakistani LIS research focused on a few subject areas. Pakistani LIS researchers gave little attention to many subjects and completely ignored others. More than a quarter (26.72%) of the total items focused on “information treatment for information services” while 22% were related to “libraries as physical collections.” Other areas with some attention included “industry, profession and education” (12.32%) and “theoretical and general aspects of libraries and information” (11.40%). Researchers paid little attention to “housing technologies,” “technical services in libraries, archives and museums,” and “management.” 相似文献

This review article considered the nature of styles and strategies and then surveyed work on cognitive styles. Different researchers have used a variety of labels for the styles they have investigated. Analysis of the way in which they assessed style, its effect on behaviour and performance, and studies of the relationship to other labels, suggested that the labels may be grouped into two principal cognitive styles. These were labelled the Wholist‐Analytic and Verbialiser‐Imager dimensions. A computer presented method of assessing the position of an individual on these dimensions was described. 相似文献
