Learners who enrol in massive open online courses (MOOCs) have different backgrounds and tend to have different motivations than learners in traditional courses. Based on value-expectancy theory, an instrument was developed to measure motivation for enrolling in a programming MOOC. A study with 1229 adult participants in Estonian-language programming course “About Programming” was conducted to validate the instrument. Results of confirmatory factor analysis validated the 7-factor scale named factors influencing enrolment in MOOC (FIEM). FIEM comprises three factors of expectancies, three factors of values and one factor of social influence. The highest and lowest rated motivational factors influencing enrolment in programming MOOC are discussed in the paper. Interest in and expectations for the course, personal suitability of distance learning and suitability for family and work are the highest-rated motivational factors for those who enrol in MOOC. Usefulness related to own children, social influence and usefulness to related to certification were the lowest rated. The results of this study can be useful for designers of programming MOOCs and the developed scale might be used in future studies.  相似文献   

Digital Module 05: Diagnostic Measurement—The G‐DINA Framework https://ncme.elevate.commpartners.com     

Wenchao Ma  Jimmy de la Torre 《Educational Measurement》2019,38(2):114-115

In this ITEMS module, we introduce the generalized deterministic inputs, noisy “and” gate (G‐DINA) model, which is a general framework for specifying, estimating, and evaluating a wide variety of cognitive diagnosis models. The module contains a nontechnical introduction to diagnostic measurement, an introductory overview of the G‐DINA model, as well as common special cases, and a review of model‐data fit evaluation practices within this framework. We use the flexible GDINA R package, which is available for free within the R environment and provides a user‐friendly graphical interface in addition to the code‐driven layer. The digital module also contains videos of worked examples, solutions to data activity questions, curated resources, a glossary, and quizzes with diagnostic feedback.  相似文献   

大学生孤独感对手机成瘾倾向的影响:生命意义感的调节作用     

陆娟  宫火良 《保定学院学报》2020,(3):95-100

为了探究大学生孤独感、手机成瘾倾向和生命意义感之间的关系,采用UCLA孤独量表、大学生手机成瘾倾向量表、人生意义感问卷,选取408名大学生作为被试进行问卷调查。结果发现:(1)孤独感与手机成瘾倾向呈显著性正相关,生命意义感与手机成瘾倾向呈显著性负相关,孤独感和生命意义感相关性不显著;(2)孤独感和生命意义感都显著预测手机成瘾倾向,生命意义感在孤独感和手机成瘾倾向之间的调节效应显著,低生命意义感大学生的孤独感对手机成瘾倾向的预测力更强。因此,大学生的孤独感能正向预测手机成瘾倾向,生命意义感能调节二者之间的关系,低水平的生命意义感会加剧孤独感对手机成瘾倾向的预测作用,而高水平的生命意义感会使孤独感对手机成瘾倾向的影响较小。  相似文献   

The Influence of Hygroscopic Materials on the Fluctuation of Relative Humidity in Museums Located in Historical Buildings     

C. Ferreira  V. P. de Freitas 《文物保护研究》2020,65(3):127-141

ABSTRACT

The preservation of artefacts in museum collections is profoundly affected by fluctuations in temperature and, especially, relative humidity (RH). Since the late nineteenth century, many studies have been carried out on the best way to control hygrothermal conditions. In old buildings located in maritime temperate climate zones (such as Portugal) with strong thermal inertia, and which have low ventilation rate (relative to the volume and number of visitors), daily and seasonal hygroscopic inertia may help to assure the maintenance of RH stabilization conditions. The use of expensive active systems may be minimized through the passive behaviour of internal finishing building materials. This work presents the results of an experimental laboratory study conducted in a flow chamber to demonstrate the enormous potential of hygroscopic materials in stabilizing interior relative humidity. Based in these results and in-situ monitoring in a museum housed in a building, located in Porto, with a typical construction of the 1950s (granite masonry and reinforced concrete slabs), a numerical analysis was done to quantify the influence of hygroscopic materials in stabilizing the interior relative humidity.  相似文献

中药组方对提高有氧耐力运动员成绩的作用   总被引：2，自引：0，他引：2  

李勤  周新华  李娟 《体育学刊》2001,8(4):55-57

把运动性疲劳的机体视为微细损伤的集合体,据此认识进行中药组方.通过对20名耐力跑运动员进行3个月分组对照实验后,测定实验前后的血色素(Hb)、个体乳酸阈值的跑速、红细胞(RBC)-SOD活性、RBC-GSH-Px活性、血浆丙二醛(MDA)的含量、RBC-MDA含量、定量负荷后血乳酸恢复速率和5000m跑最好成绩变化等.结果显示:服用中药组的各项指标和运动成绩均明显优于对照组(P＜0.05),表明本中药组方具有保护组织细胞、延迟疲劳出现和加快机能恢复的效果,对提高耐力运动成绩有良好的作用.  相似文献   

关于审判监督程序法律设置的探析     

祝娟  李英 《贵阳金筑大学学报》2001,(3)

审判监督程序是我国刑事诉讼中的一项重要补救程序。笔者在对这一程序进行分析后认为,法院不能成为审判监督程序的提起机关。如果由法院提起审判监督程序,会导致诉讼职能的混淆,导致法律监督的错位,引起证据规则的混乱,带来上诉不加刑原则的虚置等后果。从完善审判监督程序出发,提出审判监督程序的提起机关一体化,对按审判监督程序审理的案件一律开庭审理,从而保证审判监督程序的作用得到充分发挥。  相似文献
