Economics and Business Education: A Comparative Study Of The Ukraine and The United States
No full textI examined seven different groups of secondary students from the USA and Ukraine, ranging from those with 9 hours of economics instruction to those who had no formal training. The TEL means were tested using a Chi Square test of independence. This study clearly demonstrates two important findings. First, the Ukraine with all of its problems has done a miraculous job of improving both interest in economics and producing more informed students. A second finding is that both countries need to improve education in business in their curriculum if they are to reach the majority of students
Mapping the components of finance cases using the cognitive flexibility model
No full textThe theory of cognitive flexibility provides a strong conceptual framework for integrating the multifarious events and situations that combine to form the core of cases used in upper-level finance courses. Transference is the basic tenet of case-based learning. Students must be able to transfer their knowledge and critical thinking skills from one case to another. The issue addressed in this paper is one of practicality. How does one use the cognitive flexibility approach as a pedagogical scaffolding to construct case-based courses in finance? The purpose of this paper is to suggest a means for constructing the learning objects interface for a set of core finance cases and to illustrate how these system components are used to facilitate the learners\u27 cognitive and metacognitive development
Interteach: The Effects of Active Engagement Compared to Passive Lectures
Get PDFPrevious research has indicated how Boyce and Hineline’s (2002) interteaching technique is an effective teaching approach compared to traditional methods. Although researchers have examined the efficacy of various components within interteaching, few have altered the lecture component to increase active engagement. Saville et al., (2011) compared the effects of lectures (delayed, regular, and none), concluding no significant difference in performance between delayed and regular lectures within interteaching. Although delaying the lecture showed no difference in performance, the study concluded that removing the lecture component affected test scores. The current study was designed to evaluate the efficiency of the lecture component through modification by randomizing two teaching conditions within the lecture component. The present investigation assesses student performance through quiz scores by comparing active engagement to passive lectures between two graduate classes. The study revealed student performance at an equivalent level for passive and active lectures. Although active engagement produced higher average test scores for Group 1, there was an insignificant difference between the conditions on account of student performance
Video Modeling Using the Additional Salient Feature of Phonetic Hand Gestures to Teach Vocal Skills
Get PDFVideo modeling has become an effective tool for practitioners in teaching a variety of essential skills to individuals, especially children diagnosed with autism spectrum disorder (ASD). Video modeling is not only considered a highly effective intervention for skill acquisition, but it is also a consistent, practical, and cost-effective evidence-based teaching strategy utilized by many professionals. Research has also expanded to evaluate video modeling with additional salient features (s) to increase the effectiveness of video modeling. Although a multitude of research has explored the effectiveness of video modeling, there is limited research integrating the use of a speech-language pathology intervention strategy— specifically phonetic hand gestures—with video modeling to address social communication goals and teach vocal skills to individuals with varying exceptionalities. Therefore, the purpose of this study is to evaluate the use of video modeling with the additional salient feature of phonetic hand gestures to teach vocal skills to children diagnosed with diverse exceptionalities. Results indicated that the presentation of video modeling was deemed more effective in teaching vocal skills than without video modeling. Results vary for each participant
Off the Rails: A Path Forward for High-Speed Rail in the Northeast Corridor
No full textThis thesis seeks to determine the major factors hindering the development of high-speed rail (HSR) in the Northeast Corridor of the United States. After conducting a PESTL analysis to determine the political, economic, social, technological, and legal roadblocks to HSR, the author discovered a myriad of inefficiencies and areas of concern. These included partisan gridlock, inadequate funding for Amtrak, American exceptionalism, outdated infrastructure, nonenforcement of laws regarding the preference of passenger rail over freight rail on shared railways, and, perhaps most critically, a lack of a unified and comprehensive vision for HSR. After analyzing these factors, the author proposed two diverging paths forward – make adjustments to the current Acela higher-speed trains or introduce a new, technologically advanced Maglev system. The former is more immediately feasible in an era of hesitancy toward major public investment and would include some minor changes like enforcing pre-existing laws. The latter would allow the US to create HSR that leads the world and allows them to capitalize on its benefits to the greatest extent possible. The author argues that creating the Maglev is the optimal approach under the proper conditions and with a strong enough coalition. While this study provides clarity on the current issues pertaining to HSR and elucidates two paths forward, further research must be done on the creation of a Maglev in the Northeast Corridor to determine how to most effectively facilitate that project
Long-Term Antibacterial Efficacy of Silver (I) Cyanoximates Against Streptococcus mutans UA159 Biofilm Growth
No full textStreptococcus mutans is the primary causative agent of dental caries due to its ability to form resilient multispecies biofilms. These biofilms promote acid production and degradation of the protective layers of the tooth, making biofilm formation a target for novel treatments. Silver(I) cyanoximates are of interest as alternatives to traditional antimicrobials and antibiotics due to the high UV and heat resistivity as well as poor solubility of the cyanoxime ligand paired with the well-established antimicrobial silver ion. Previous research has shown that silver(I) cyanoximates can effectively inhibit S. mutans biofilm formation after 24 hours in vitro. This study aimed to evaluate the time-dependent efficacy of the most effective silver(I) cyanoximates—Ag(ECO), Ag(PiCO), and Ag(2PiCO)—in inhibiting S. mutans biofilm formation. In vitro minimum biofilm inhibitory concentration (MBIC) assays were conducted over 24, 48, and 72 hours, and optical density was measured using spectrophotometry to determine biofilm formation. The results of this study indicate that Ag(ECO), Ag(PiCO), and Ag(2PiCO) were all effective and exhibited stable and sustained inhibition of biofilm formation over time at a concentration of 32 μg/ml. Our findings suggest that these silver(I) cyanoximates show promise as antimicrobial and antibiotic alternatives in the field of dentistry
Justifying the Opposite: A Pedagogical Reminder for those Teaching Financial Ratio Analysis
No full textAlthough introductory finance texts may be clear and instructors may be thorough, students often exhibit an extremely superficial understanding of financial ratio analysis upon leaving their introductory classes. We find that students’ understanding can be enhanced by requiring them to justify why the opposite of their initial impression of a financial ratio may be correct. Thus, students – or other analysts – may be too quick to judge whether the value of a particular financial ratio is “good” or “bad.” This approach requires little additional classroom time, yet seems to create a better understanding of the interrelated financial variables comprising the ratio
