The Effects Of Subject Presentation Types In Problem Based Learning (PBL) Problems On Student Motivation: A Pbl Implementation In Speech Language Pathology

Problem-Based Learning (PBL) is an evidence-based instructional approach designed to maximize one’s ability to use static knowledge as evidence for solving authentic problems (Barrows, 1986). Students have been observed as underprepared or skipping steps during the PBL process due to fatigue or low motivation (Czabanowska, Moust, Meijer, Schr��-B夫, & Robertson, 2012). This study considered the impact of the presentation of the PBL subject (i.e., the key character involved in the problem) on student motivation within the context of Speech and Voice Science curricula. The results of this mixed-methods study showed the frequency of engagement behaviors declined overall. Although engagement levels declined and fatigue appeared to play a role, most students identified the final problems designed with a combination of higher social presence (i.e., audio-visual, face-to-face interaction) and challenging content as the most motivating. Students were able to develop a sense of ownership and responsibility for their problem-solving efforts, fostered by the direct interaction with the problem subject. This study also provides an example of a PBL implementation at the undergraduate level in Speech Language Pathology

A guide to motivating students to twist to better spelling

Students learn and retain more when they enjoy the process or avenue of learning. Students have fun learning to spell when visual, auditory, and hands-on learning are included in the process. In addition, the intervention project can be used to support and assist second language learners. The benefits from this intervention project will not only strengthen students\u27 phonemic and spelling foundation, but will also enhance their reading comprehension and writing effectiveness

Comparison of Porcelain Surface and Flexural Strength Obtained by Microwave and Conventional Oven Glazing

Statement of problem. Although the superior qualities of microwave technology are common knowledge in the industry, effects of microwave glazing of dental ceramics have not been investigated. Purpose. The purpose of this study was to investigate the surface roughness and flexural strength achieved by glazing porcelain specimens in a conventional and microwave oven. Material and methods. Thirty specimens of each type of porcelain (Omega 900 and IPS d.Sign) were fabricated and sintered in a conventional oven. The specimens were further divided into 3 groups (n=10): hand polished (using diamond rotary ceramic polishers), microwave glazed, and conventional oven glazed. Each specimen was evaluated for surface roughness using a profilometer. The flexural strength of each specimen was measured using a universal testing machine. A 2-way ANOVA and Tukey HSD post hoc analysis were used to determine significant intergroup differences in surface roughness (α=.05). Flexural strength results were also analyzed using 2-way ANOVA, and the Weibull modulus was determined for each of the 6 groups. The surfaces of the specimens were subjectively evaluated for cracks and porosities using a scanning electron microscope (SEM). Results. A significant difference in surface roughness was found among the surface treatments (P=.02). Follow-up tests showed a significant difference in surface roughness between oven-glazed and microwave-glazed treatments (P=.02). There was a significant difference in flexural strength between the 2 porcelains (P Conclusions. The surface character of microwave-glazed porcelain was superior to oven-glazed porcelain. Omega 900 had an overall higher flexural strength than IPS d.Sign. Weibull distributions of flexural strengths for Omega 900 ovenglazed and microwave-glazed specimens were similar. SEM analysis demonstrated a greater number of surface voids and imperfections in IPS d.Sign as compared to Omega 900

Serving as a Peer Reviewer: Rewards and Challenges

The practice of peer review is essential to ensure academic quality of articles published in professional journals. Nurses with expertise in evidence-based best practices are often well-qualified to serve as peer reviewers. Peer reviewers play an integral role in the peer review process to disseminate quality information. The peer-reviewed International Journal of Faith Community Nurses is the official journal of Faith Community Nurses International. Individuals interested in faith community nursing can aide in advancing this specialty of nursing practice by serving as a peer reviewer. The purpose of this article is to explore the peer review process, and to identify rewards and challenges of serving as a peer reviewer

Methods for Increasing Leptin Levels Using Nicotinic Acid Compounds

The invention relates to the use of nicotinic acid and nicotinic acid esters, such as nicotinic acid alkyl esters, to increase the amount of leptin in a subject. As a result, one can treat conditions, such as conditions characterized by wounds, by administering sufficient amounts of nicotinic acid or nicotinic acid ester to increase leptin levels to alleviating amounts. Various conditions and modes of treatment are disclosed

Topical Micronutrient Delivery System and Uses of Thereof

The invention involves methods and compositions useful in delivering micronutrients to cells. By formulating the micronutrient in the form of an ester that is convertible to the active form of the micronutrient, one can combine it with a co-ester that inhibits esterases, so that the micronutrient can reach the targeted cells prior to degradation. Both methods and compositions are described

Methods and Compositions Useful in Enhancing Oxygen Delivery to Cells

The invention discloses compositions and methods which are useful in improving delivery of oxygen to cells. The compositions require at least one derivative of a compound. The derivatives are chosen to have log P values below about 6.0
