Reading-Specific Flexibility Moderates The Relation Between Reading Strategy Use And Reading Comprehension During The Elementary Years, Emily K. Gnaedinger, Alycia M. Hund, Matthew S. Hesson-Mcinnis Jan 2016

Reading-Specific Flexibility Moderates The Relation Between Reading Strategy Use And Reading Comprehension During The Elementary Years, Emily K. Gnaedinger, Alycia M. Hund, Matthew S. Hesson-Mcinnis

Faculty Publications – Psychology

The goal was to test whether cognitive flexibility moderates the relation between reading strategy use and reading comprehension during the elementary years. Seventy-five second through fifth grade students completed a think aloud task and a metacognitive questionnaire to measure reading strategies, two card-sorting tasks to measure general and reading-specific cognitive flexibility, and one standardized measure of reading comprehension, as well as measures of oral reading fluency and vocabulary. As expected, oral reading fluency and vocabulary predicted reading comprehension, as did reading-specific flexibility. Importantly, reading-specific flexibility had a significant moderating effect, over and above the other effects. Specifically, weak reading-specific flexibility …

Chair Support, Faculty Entrepreneurship, And The Teaching Of Statistical Reasoning To Journalism Undergraduates In The United States, Robert J. Griffin, Sharon Dunwoody Jan 2016

Chair Support, Faculty Entrepreneurship, And The Teaching Of Statistical Reasoning To Journalism Undergraduates In The United States, Robert J. Griffin, Sharon Dunwoody

College of Communication Faculty Research and Publications

Statistical reasoning is not the same as doing calculations. Instead, it involves cognitive skills such as the ability to think critically and systematically with data, skills important for everyday news work and essential for the era of data journalism. Twin surveys of the chairs of undergraduate journalism programs in the United States, conducted 11 years apart, revealed that those who perceived benefits from statistical reasoning instruction were more likely to reward entrepreneurship (faculty attempts to integrate this instruction into their classes), but with slow gains over time in the fairly small number of such faculty. Being consistent with university goals …

Old New Media: Closed-Circuit Television And The Classroom, Amanda R. Keeler Jan 2016

Old New Media: Closed-Circuit Television And The Classroom, Amanda R. Keeler

College of Communication Faculty Research and Publications

This article explores closed-circuit television (CCTV) and its ‘bright promise stage’, as it was contemplated, marketed, and implemented as a low-cost classroom tool. After the Federal Communications Commission issued the 1952 Sixth Report and Order, many schools and communities sought to bring educational television to the classroom. However, this model was financially out of reach for most. CCTV was a more affordable version of educational television that could cater to specific classroom needs and allow schools to create their own in-house network. CCTV represents just one of many new technologies that have been promoted as ideal for classroom instruction over …

Idiom Token Classification Using Sentential Distributed Semantics, Giancarlo Salton, Robert J. Ross, John D. Kelleher Jan 2016

Idiom Token Classification Using Sentential Distributed Semantics, Giancarlo Salton, Robert J. Ross, John D. Kelleher

Conference papers

Idiom token classification is the task of deciding for a set of potentially idiomatic phrases whether each occurrence of a phrase is a literal or idiomatic usage of the phrase. In this work we explore the use of Skip-Thought Vectors to create distributed representations that encode features that are predictive with respect to idiom token classification. We show that classifiers using these representations have competitive performance compared with the state of the art in idiom token classification. Importantly, however, our models use only the sentence containing the tar- get phrase as input and are thus less dependent on a potentially …
