Portraying intelligence: children’s drawings of intelligent men and women in Finnish and Russian Karelia

This study sets out to examine Finnish and Russian children’s representations of intellectual competence as contextualised in the hierarchies of abilities, age and gender. Finnish and Russian pupils, aged 11–12?years, were asked to draw pictures of an intelligent person and an ordinary person. It was found that gender appearance of intelligent men and women was less heterosexual than that of ordinary men and women. In Russian pictures, the intelligent characters, especially women, were widely separated from the ordinary ones in terms of cognitive-mental features. In Finnish depictions, the differentiation between the intelligent and ordinary characters, especially women, was not so categorical and was primarily based on status. It appears that Russian children are apt to relate their representations of intellectual ability to the institutionalised systems of cognitive competence, education and science, whereas Finnish children associate intelligence to social success as well. Further, cultural and gender-related hierarchies of age seemed to reflect in the children’s images.     

Academics’ conceptions of assessment and their assessment practices

The present study focuses; firstly, on analysing academics’ conceptions of the purpose of assessment; secondly, on their assessment practices; and thirdly, on the relationship between their conceptions and practices. The data consisted of interviews with 28 pharmacy teachers. The analysis resulted in a continuum of categories of conceptions, from reproductive conceptions with an emphasis on measuring the reproduction of correct information, to more transformational conceptions with an emphasis on the development of students’ thinking and understanding. Although broad variation in assessment practices was recognised, teachers mostly described the use of traditional forms of assessment. Analysis of the relationship between conceptions and practices revealed high consistency between conceptions and practices.     

快速阅读训练对小学生阅读效果影响的实验研究

本研究以小学五年级学生为被试,经过12周的快速阅读训练,使学生初步掌握快速阅读训练的技能,据此探索快速阅读训练和阅读方式(先看文章再回答问题、先看问题再读文章)对小学生阅读效果的影响。结果发现:第一,快速阅读训练可显著减少学生的总阅读时间、提高阅读速度,但不影响阅读理解率;第二,先看问题再读文章的阅读方式在主旨题目的理解率上有其独特优势;第三,阅读方式和快速阅读训练在学生阅读效果上不存在交互作用,即两者不存在相互影响的问题。     

Optimization of enzymatic hydrolysis of cassava to obtain fermentable sugars

This work evaluates the enzymatic hydrolysis of starch from cassava using pectinase, α-amylase, and amyloglucosidase. A central composite rotational design (CCRD) was carried out to evaluate the effects of amyloglucosidase, pectinase, reaction time, and solid to liquid ratio. All the experiments were carried out in a bioreactor with working volume of 2 L. Approximately 98% efficiency hydrolysis was obtained, resulting in a concentration of total reducing sugar released of 160 g/L. It was concluded that pectinase improved the hydrolysis of starch from cassava. Reaction time was found to be significant until 7 h of reaction. A solid to liquid ratio of 1.0 was considered suitable for hydrolysis of starch from cassava. Amyloglucosidase was a significant variable in the process: after its addition to the reaction media, a 30%–50% increase in the amount of total reducing sugar released was observed. At optimal conditions the maximum productivity obtained was 22.9 g/(L·h).     

Using NLM Exhibits and Events to Engage Library Users and Reach the Community

In an effort to reach out to library users and make the library a more relevant, welcoming place, the University of Florida's Health Science Center Library hosted exhibits from the National Library of Medicine's (NLM) Traveling Exhibition Program. From 2010 through 2012, the library hosted four NLM exhibits and created event series for each. Through reflection and use of a participant survey, lessons were learned concerning creating relevant programs, marketing events, and forming new partnerships. Each successive exhibit added events and activities to address different audiences. A survey of libraries that have hosted NLM exhibits highlights lessons learned at those institutions.     

Professional development schools and special education: A promising partnership?

Abstract

Professional development schools (PDSs) have become an important component of preservice teacher preparation. Researchers investigating the effect of the PDS model on the principal stakeholders (preservice teachers, classroom teachers, students, and university faculty) have reported many positive effects. The role of the PDS in special education teacher preparation, however, appears to be less well defined. This article focuses on PDS participation of special education teacher preparation programs and addresses the apparent reluctance to embrace the PDS model.     

Hands-on Activities and Their Influence on Students’ Interest

This study investigates the influence of hands-on activities on students’ interest. We researched whether students with experience in specific hands-on activities show higher interest in these activities than students without experience. Furthermore, the relationship between the quality of the hands-on experience and interest in the respective activity was examined. In total, 28 typical hands-on activities of biology education were considered. The activities were divided into the categories experimentation, dissection, work with microscopes, and classification. A total of 141 students from the 11th grade completed questionnaires on interest in the hands-on activities, their experience with each activity, and the quality of the respective experience. Students’ interest in experimenting, working with microscopes, dissecting and classifying tends to benefit from performing hands-on activities. However, findings indicated that the performance of various hands-on activities can influence students’ interest differently. For seven hands-on activities, we identified a positive effect of hands-on experience on interest, while in one case, practical work appeared to have influenced students’ interest negatively. However, for most hands-on activities, no effect of experience on interest was found. The quality of hands-on experiences showed positive correlations with interest in the respective hands-on activities. Therefore, this paper argues in favour of designing biology lessons that allow for experiences with hands-on activities that also interest students. Our findings underline the necessity of investigating the effects of various hands-on activities in a differentiated manner.     

The price of admission: Who gets into private school,and how much do they pay?

I analyze how elementary and secondary private schools decide which students to admit from their applicant pool using mechanism design theory. The problem for an individual private school of who to admit and how much to charge in tuition, is complicated by the existence of peer-effects: the value students place on attending school is increasing with the average ability of the entire class at that school. This feature, coupled with the fact that students can always attend public school for free, places constraints on the types of classes the private school can admit. In my model, students have an ability type that is known to the school through testing, as well as a wealth type that is private information. Students report their wealth to the school and on the basis of the results from the ability test and wealth reports, the school institutes an allocation rule and a payment rule. Allocation rules which only admit all high ability students and no others, or all high wealth students and no others are not feasible. I utilize a simple example to show how in a revenue-maximizing allocation, the private school always under-admits the highest ability students relative to the allocation rule that maximizes social welfare.
