Analysis of self-regulated learning processing using statistical models for count data

Researchers often use measures of the frequency of self-regulated learning (SRL; Zimmerman, American Educational Research Journal, 45(1), 166–183, 2000) processing as a predictor of learning gains. These frequency data, which are really counts of SRL processing events, are often non-normally distributed, and the accurate analysis of these data requires the use of specialized statistical models. In this study, we demonstrate how to implement and interpret count statistical models in path and latent profile analyses to investigate the role of SRL as a mediator of the relation between pretest and posttest conceptual understanding. Our findings from a sample of 170 college students using a computer to learn about the circulatory system show that SRL does mediate the aforementioned relation, and that count models are a more accurate representation of SRL processing data than standard analysis models based on ordinary least squares estimation. The results of our path analyses revealed which specific SRL processes were related to learning, above and beyond the effect of prior knowledge. Our latent profile analysis revealed two groups of participants, indicative of Brophy’s (2004) model of schematic and aschematic learners. We conclude with implications and future directions for basic and applied SRL research.

Matters of Form: Questions of Race,Identity, Design,and the U.S. Census

This case examines how functionalist approaches manifest culturally based on users’ contexts. The authors conduct a critical visual semiotic analysis of the race and Hispanic origin questions on the 2010 U.S. Census form, demonstrating how incongruities in design potentially harm people. This demonstrates a need for adding critical analyses to design and research and it refocuses the Society for Technical Communication’s value of promoting the public good on to design and documentation in order to fight injustice.

棒喝:虚火正旺危机四伏的大学英语教育

现今的大学英语教育,虚火正旺隐患多多,对专业学习冲击最大,直接导致本科教育质量的下滑。目标过高,导向偏差是其主要成因。从长计议,必须将英语考级社会化,坚决取消英语考级证书与毕业证、学位证相挂钩;按学校不同情况,分等论级区别对待。确定不同的英语教学目标要求;同时应引导社会舆论,淡化用人单位对英语考证的不适当要求;把英语教育的主要精力投放到外语学院及专门人才培养上,以“少而精”取代“全民性”。     

An Examination of Text Complexity as Characterized by Readability and Cohesion

To better understand dimensions of text complexity and their effect on the comprehension of adolescents, 103 high school seniors were randomly assigned to 4 groups. Each group read versions of the same 2 informational passages and answered comprehension test items targeting factual recall and inferences of causal content. Group A passages had a challenging readability level and high cohesion; Group B passages had an easier readability and low cohesion; Group C passages had a challenging readability level and low cohesion; and Group D passages had an easier readability and high cohesion. Students in Group D significantly outperformed students in Group C (g = 0.78). Although the effect sizes of comparisons among all groups ranged from g = 0.13 to 0.73, no other comparisons were statistically significant. Results indicate that adolescents’ reading comprehension is dually influenced by a text's readability and cohesion. Implications for matching readers to instructional text are discussed.

Exploring anatomy and physiology using iPad applications

This study examined the use of iPads with anatomy applications (apps) in the laboratory sections of the largest undergraduate course at the university, Anatomy and Physiology, serving more than 300 students. The majority of these students were nursing, exercise science/physical education and biology majors. With a student survey (student opinion) and student practicum grades as metrics, this study determined whether the introduction of this novel mobile technology improved student grades and aided the students in learning the course material. The results indicated that students’ grades improved with the introduction of the iPads, and 78% of the students reported that the iPads facilitated their ability to learn the course material. There was a positive association between frequency of app use and standardized mastery of the course material, as students who used the apps more frequently scored higher and indicated that they felt as though they had learned the material more comprehensively. Owning or having an iPad at home did not have a significant effect on the learning of the material. The general consensus by students was that iPad anatomy apps should be used frequently to better develop student understanding of the course material.

Regarding uncertainty in teachers and teaching

The literature on teacher uncertainty suggests that it is a significant and perhaps inherent feature of teaching. Yet there is disagreement about the effects of these uncertainties on teachers as well as about the ways that teachers should regard them. Recognition of uncertainties can be viewed alternatively as a liability or an asset to effective teaching. Findings from the literature on uncertainties in teaching are summarized and analyzed, including explanations in the research about what accounts for and contributes to uncertainties. Recommendations for research and professional development are provided.     

叙事谋略与元代戏曲的人文情怀

元代戏曲的叙事谋略表现于典型冲突模式的构建与解决。具体来看涉及情礼、理法、伦理、人性四种模式和现实、浪漫两种冲突解决方式。这种叙事谋略背后潜隐着剧作家们的独特思想理念和审美价值趋向,体现了他们的人文情怀,即对普通民众生存状态的关注、对正常人欲美好人性的肯定颂扬以及对人道正义的坚守。
