A High-Enrollment Course-Based Undergraduate Research Experience Improves Student Conceptions of Scientific Thinking and Ability to Interpret Data

We present an innovative course-based undergraduate research experience curriculum focused on the characterization of single point mutations in p53, a tumor suppressor gene that is mutated in more than 50% of human cancers. This course is required of all introductory biology students, so all biology majors engage in a research project as part of their training. Using a set of open-ended written prompts, we found that the course shifts student conceptions of what it means to think like a scientist from novice to more expert-like. Students at the end of the course identified experimental repetition, data analysis, and collaboration as important elements of thinking like a scientist. Course exams revealed that students showed gains in their ability to analyze and interpret data. These data indicate that this course-embedded research experience has a positive impact on the development of students’ conceptions and practice of scientific thinking.     

The incorporation of hands-on tasks in an online course: an analysis of a blended learning environment

This article describes the design and evaluation of a blended online/face-to-face course completed by more than 6000 learners throughout the United States of America and internationally. The educational impact was monitored using a variety of evaluation strategies. The results, in terms of achieved knowledge and overall satisfaction, indicate that a focus on online instruction combined with face-to-face, hands-on activities showed statistically significant improvement in the learners' understanding of the course material, while also validating the impact of the curriculum in their workplace. As illustrated through the blended course design, this study further showed that online learners with greater improvement in their pre- and posttest scores also exhibited significantly greater likelihood in demonstrating competency in several areas during the hands-on portion of the course. In particular, participants working in the information systems field exhibited the highest mean difference score (21.49) on the pre- and the posttests, while those working in the laboratory had the lowest (12.17). Likewise, the odds that participants who reviewed the course contents sought to further understand their job roles was 58.2 times greater for those in information systems, while it was only 19.0 times greater for laboratory staff, than those who did not review their job roles.

The social impact of the “Digital Divide” in a Central–Eastern European country provides a comprehensive study of different “Digital Divides” existing between “emerging democracies” (or “emerging new market-oriented economies”) from Central and Eastern Europe, as well as between them and industrialized developed countries (Western Europe, USA, etc.). Former and actual influencing factors are analyzed and evaluated, basic facts and social impacts are presented, some solutions are issued. The United Nations' concerns and roles are emphasized.

The Choice Architecture of School Choice Websites

Abstract

We conducted a randomized factorial experiment to determine how displaying school information to parents in different ways affects what schools they choose for their children in a hypothetical school district. In a sample of 3,500 low-income parents of school-aged children, a small design manipulation, such as changing the default order in which schools were presented, induced meaningful changes in the types of schools selected. Other design choices such as using icons to represent data, instead of graphs or just numbers, or presenting concise summaries instead of detailed displays, also led parents to choose schools with higher academic performance. We also examined effects on parents’ understanding of the information and their self-reported satisfaction and ease of use. In some cases, there were trade-offs. For example, representing data using only numbers maximized understanding, but adding graphs maximized satisfaction at the expense of understanding.     

The Role of Strategic Planning in Accessing False-Belief Understanding

Recently, Chandler and Hala found that actively involving 3-year-olds in planning a deception facilitated performance on false-belief questions. The methodology used, however, provided no basis for determining whether the good performance of these young subjects was the result of the deceptive intent of their planning efforts, or whether other sorts of planning would have been equally effective. The research reported here systematically varied both ( a ) subjects' responsibility for planning where to relocate an object and ( b ) whether the goal behind this relocation was a deceptive one. The present research demonstrated, first, when subjects simply watched the transfer take place, it made no difference whether the object was moved for deceptive or some more practical reason. In contrast, those subjects who had themselves strategically planned a deception were markedly better at answering questions about another's false beliefs than those who simply witnessed the transfer taking place. No comparable facilitating effect was found when subjects planned a transfer but without deceptive intent. We argue that strategic planning works to underscore the importance of the belief states of others and provide opportunities not afforded by "standard" unexpected change or transfer tasks for showcasing 3-year-olds' emerging understanding of the possibility of false belief.     

Change in strategy: The relationship of attribution,expectancy, performance,and satisfaction

The purpose of the study was to examine the degree to which change in examination preparation is related to measures of attribution, expectancy, prior performance, perceived success/failure, and satisfaction. Subjects were students in an intermediate graduate statistics course. Although performance is the single best predictor of change in preparation, three attribution measures and satisfaction contributed unique predictive variance. While expectancy was significantly related to change in preparation, it did not add uniquely to the multiple correlation.
