The present study examined whether or not different input delivery modes have an effect on listening comprehension of Turkish students learning English at the university level. It investigated the effect of one single mode, which is audio-only, and three dual input delivery modes, which were audio-video, audio-video with target language subtitles and audio with PowerPoint presentation, on listening comprehension. The data have been gathered through: a listening proficiency exam, a topic familiarity questionnaire, listening comprehension tests, think-aloud protocols and a semi-structured focus group interview. Analysis of data demonstrated that the students’ listening comprehension scores were significantly lower in audio-video with subtitles mode. In addition to this, the students stated that they experienced most confusion and anxiety in understanding through audio-video with subtitles. Moreover, the students mentioned that they were most successful in the audio with PowerPoint presentation mode. Results also indicated that the students were influenced by their pre-university listening class experiences, meaning that they were most accustomed to the audio-only mode, and therefore felt most relaxed when they listened only. 相似文献

Freshmen Learning Communities (FLCs) or Freshmen Interest Groups (FIGs) recently emerged on the landscape of higher education as an innovative means of improving educational outcomes. Building around a cohort‐based pedagogical model, FLCs use thematic foci, block scheduling, and faculty collaboration to ease the transition into the first‐year college experience. This paper outlines the logic and structure of a criminology/criminal justice‐based FLC. It details how pedagogical variations such as writing across the curriculum and web‐based design can be included. A large body of input and output data is considered that measures how students respond to the FLC experience. 相似文献

Eliminating noisy information and extracting informative content have become important issues for web mining, search and accessibility. This extraction process can employ automatic techniques and hand-crafted rules. Automatic extraction techniques focus on various machine learning methods, but implementing these techniques increases time complexity of the extraction process. Conversely, extraction through hand-crafted rules is an efficient technique that uses string manipulation functions, but preparing these rules is difficult and cumbersome for users. In this paper, we present a hybrid approach that contains two steps that can invoke each other. The first step discovers informative content using Decision Tree Learning as an appropriate machine learning method and creates rules from the results of this learning method. The second step extracts informative content using rules obtained from the first step. However, if the second step does not return an extraction result, the first step gets invoked. In our experiments, the first step achieves high accuracy with 95.76% in extraction of the informative content. Moreover, 71.92% of the rules can be used in the extraction process, and it is approximately 240 times faster than the first step. 相似文献

This study examines pre-school children's learning styles by utilising a mathematical model. The model uses a Euclidean geometry algorithm to generate a graphical representation of the learning styles. The algorithm of the developed mathematical model was developed as a practical application of the theoretical assumptions. Index of Learning Styles for Children (ILSC), developed by one of the researchers, has been applied to a total of 301 five-year-old children. Results of the study indicate that children utilise the active, cognitive and visual learning styles under the control of the right hemisphere, and the sequential (analytical) learning styles under the control of the left hemisphere. The modelling algorithm reveals that the children's learning style preferences are shifted towards the right hemisphere at the rate of 8%. The results also provide empirical support that the developed model can mathematically explain the theoretical assumptions it is based on. 相似文献

This study examined substantive political coverage of the first presidential debate and the political conventions in 2004 on The Daily Show with Jon Stewart and the broadcast television networks' nightly newscasts. The study found the networks' coverage to be more hype than substance and coverage on The Daily Show with Jon Stewart to be more humor than substance. The amount of substantive information in The Daily Show with Jon Stewart and the broadcast network newscasts was the same, regardless of whether the unit of analysis was news stories about the presidential election campaign or the entire half-hour program. 相似文献

This study investigated how preservice teachers develop collective efficacy when preparing lesson plans for a science methods course, and how this collective efficacy changed over time. The data were collected from four preservice science teachers working in a group to fulfil the requirements of the course. Findings revealed that four factors, including collaborative work, sharing the same goal, attitudes towards group work and group cohesion, played an important role in the development of collective efficacy among preservice teachers. The study also showed that collective efficacy improved continuously over the semester. 相似文献
