Using VoiceThread to Create Community in Online Learning

A sense of belonging to a learning community has been identified as one of the factors contributing to greater student satisfaction and persistence in online education programs. Using the community of inquiry framework as a theoretical guide, the purpose of this study was to explore the role of VoiceThread, a web-based platform that facilitates cloud communication, in creating a sense of community for U.S. adult learners in the online environment. This study surveyed 39 students in a College of Education fully online master’s program and in a blended doctoral program regarding their experiences using VoiceThread in their courses. Results indicate that students perceive VoiceThread positively in the creation of online community. Students reported feeling more connected their classmates due to the tool’s ability to add voice to online activities. Students also felt more connected to their instructor due to VoiceThread’s ability to humanize, or make the instructor seem real.     

Developing a Test of Scientific Literacy Skills (TOSLS): Measuring Undergraduates�� Evaluation of Scientific Information and Arguments

Life sciences faculty agree that developing scientific literacy is an integral part of undergraduate education and report that they teach these skills. However, few measures of scientific literacy are available to assess students’ proficiency in using scientific literacy skills to solve scenarios in and beyond the undergraduate biology classroom. In this paper, we describe the development, validation, and testing of the Test of Scientific Literacy Skills (TOSLS) in five general education biology classes at three undergraduate institutions. The test measures skills related to major aspects of scientific literacy: recognizing and analyzing the use of methods of inquiry that lead to scientific knowledge and the ability to organize, analyze, and interpret quantitative data and scientific information. Measures of validity included correspondence between items and scientific literacy goals of the National Research Council and Project 2061, findings from a survey of biology faculty, expert biology educator reviews, student interviews, and statistical analyses. Classroom testing contexts varied both in terms of student demographics and pedagogical approaches. We propose that biology instructors can use the TOSLS to evaluate their students’ proficiencies in using scientific literacy skills and to document the impacts of curricular reform on students’ scientific literacy.     

Not Mechanics but Meaning: Error in Tertiary Students' Writing

This paper draws upon an extended report to the now‐defunct Commonwealth Tertiary Education Commission which analyses the errors found in over 300,000 words of writing in a British History course, produced by two groups of first year students in 1974 and 1984. There were no statistically significant differences between the two year groups. More interestingly and importantly, the results of the study indicate that the most statistically significant elements in error‐prone writing are those concerned not so much with the formal mechanics of writing but with the constitution of meaning. We interpret these results to suggest strongly that most of the problems of those writers who make many grammatical errors in their writing are problems which do not lend themselves to ‘purely’ grammatical solutions     

Standards and assessment: coherence from the teacher’s perspective

We sought to understand how teachers’ perspectives on standards-based instructional practices, classroom assessment, and external testing do or do not show coherence and alignment. Based on survey methods (n?=?155) and interviews with a sample of secondary school teachers (n?=?9) in a large urban district in the USA, we explored general trends and individual teachers’ viewpoints. Our results suggest that the teachers’ instructional use of standards, classroom assessment preferences, and beliefs about the test-driven system are moderately correlated. Interview data provide insight into reasons teachers hold beliefs that do or do not fit well into a coherent assessment system.     

The neuroscience of perceptual categorization in pigeons: A mechanistic hypothesis

We are surrounded by an endless variation of objects. The ability to categorize these objects represents a core cognitive competence of humans and possibly all vertebrates. Research on category learning in nonhuman animals started with the seminal studies of Richard Herrnstein on the category “human” in pigeons. Since then, we have learned that pigeons are able to categorize a large number of stimulus sets, ranging from Cubist paintings to English orthography. Strangely, this prolific field has largely neglected to also study the avian neurobiology of categorization. Here, we present a hypothesis that combines experimental results and theories from categorization research in pigeons with neurobiological insights on visual processing and dopamine-mediated learning in primates. We conclude that in both fields, similar conclusions on the mechanisms of perceptual categorization have been drawn, despite very little cross-reference or communication between these two areas to date. We hypothesize that perceptual categorization is a two-component process in which stimulus features are first rapidly extracted in a feed-forward process, thereby enabling a fast subdivision along multiple category borders. In primates this seems to happen in the inferotemporal cortex, while pigeons may primarily use a cluster of associative visual forebrain areas. The second process rests on dopaminergic error-prediction learning that enables prefrontal areas to connect top down the relevant visual category dimension to the appropriate action dimension.     

An assessment of international college student adjustment

International students have realistic expectations about their adjustment to college, however, they seem to experience a more difficult transition than U.S. students. Scores on the Student Adaptation to College Questionnaire for international and U.S. students are compared. The results indicated that international students scored significantly lower on the social and the institutional attachment and goal commitment subscales. The Student Adaptation to College Questionnaire may have applications in targeting international student needs.     

Games for math: Thoughts to grow on

Every child is different when it comes to math. One child loves big numbers. Another child loves addition. A third sinks into despair at the sight of mathematical symbols — until suddenly, at age eight, an unexpected math talent develops. In one way, though, all children are the same: they like math games. Put the right game in front of a child, explain the rules, and that child will eagerly play, happy and alert.Excerpted fromGames for Math, by Peggy Kaye. © 1987.
