Pre-Service Teachers’ Perceptions of Asynchronous Online Discussion on Blackboard

The purpose of this phenomenological study was to understand students’ perceptions of using asynchronous on line discussion as a learning tool. Six pre-service teachers who took a course in educational technology applications for secondary grades at a Rocky Mountain region mid-sized university were selected to be interviewed. Phenomenological data analysis was used to analyze the interview data. The interviewees’ perceptions of the asynchronous on line discussions centered around purposes, group size, tools for learning, advantages/disadvantages, and the instructor’s role. The findings of this study provide instructors with helpful information on how students perceive asynchronous online discussion and also provide instructors with possible interventions to enhance students’ motivations for participating in asynchronous online discussion

Team Members’ Perceptions of Online Teamwork Learning Experiences and Building Teamwork Trust: A Qualitative Study

Teamwork factors can facilitate team members, committing themselves to the purposes of maximizing their own and others\u27 contributions and successes. It is important for online instructors to comprehend students\u27 expectations on learning collaboratively. The aims of this study were to investigate online collaborative learning experiences and to identify important factors that were crucial for building teamwork trust. A qualitative research method was utilized in the study. Data were collected from students\u27 responses of three open-ended questions and interviews. The results indicated that students who enjoyed working in the group setting had a good relationship with their team members and they trusted their team members. In contrast, the questionable behaviors of members (lack of communication and low level of individual accountability) were negative factors of their teamwork experiences. In addition, students considered individual accountability, familiarity with team members, commitment toward quality work, and team cohesion were important factors for building trust with team members. Quantitative analyses confirmed that teamwork trust was correlated significantly with two of the important factors for building trust indicated by team members: familiarity with members (r = .74) and team cohesion (r = .79). Implications and recommendations for future research were also discussed

Learning-related Soft Skills Among Online Business Students in Higher Education: Grade Level and Managerial Role Difference in Self-Regulation, Motivation, and Social Skill

The purpose of the study was to investigate how undergraduate and graduate business management students, as well as those who had a managerial role in their career and who did not, differ on levels of soft skills (SRL strategies, motivation, and social skills) after gender was controlled. Moreover, we intended to investigate how well soft skills factors influence business students’ successes in an online learning environment after students’ individual characteristics and learning characteristics were controlled. To serve this purpose, this study conducted MANCOVA and hierarchical multiple regression analyses on data collected from 162 students in fully online business courses. First, the results of the study indicated that graduate students had higher level of soft skills than undergraduate students, especially in self-regulation and motivation. Likewise, students with managerial experiences demonstrated a higher level of soft skills. Next, hierarchical regression analysis revealed that the final regression model with all soft skills factors included could predict approximately 34% of the variance in students learning outcomes to a statistically significant level. In addition, goal setting, self-efficacy, and social skills were found to be significant predictors. We suggest that instructors and instructional designers should realize that soft skills are important contributor to the learning outcomes. Therefore, mechanisms to enhance student soft skills should be embedded into the online course in order to improve student learning outcomes. This should be especially a priority for undergraduate online courses because undergraduate students do not demonstrate higher soft skills compared to graduate students

Learning Chinese Through a 21st Century Writing Workshop with the Integration of Mobile Technology in a Language Immersion Elementary School

Digital mobile devices such as iPads have been around for many years and have been more and more popular in K-12 classrooms. Research has pointed out the advantages of using iPads in classrooms to enhance teaching, engage learning, and promote learning outcomes. iPads have been proved to be a useful and powerful digital mobile device in language learning including speaking, listening, reading, and writing. The purpose of the study was to investigate whether a technology integrated 21st century writing workshop had an influence on the ability and attitude towards writing in Chinese for second graders enrolled in the Mandarin Chinese program in a language immersion elementary school. Twenty-four students participated in the study. Recording technology (iPad recording app), an iPad camera, and the Book Creator App were integrated into the 21st century writing workshop. A pre-survey, post-survey, and observation were used to collect data. The results of the study confirmed that writing barriers decreased when the Chinese immersion program students utilized iPads in the writing workshop. Also, the writing ability and attitudes of the Chinese immersion program students improved after the completion of their 21st century writing workshop

Relationships between Connectedness, Performance Proficiency, Satisfaction, and Online Learning Continuance

Maintaining momentum is vital in terms of how soon students can complete a program, especially for those who are in the early stage of taking online courses. This study attempted to extend the existing literature by examining the influence of online students’ perceived sense of connectedness, performance proficiency, and satisfaction on their intentions to continue an online learning course. A quantitative survey approach was adopted to test our hypothesized structural model. Three hundred and sixty-nine students who had taken fewer than three fully online courses participated in this study. The results revealed that three out of four testing hypotheses were all supported at the 0.01 significance level, and one of the path coefficients indicated that online students’ confidence in their ability or competency to perform academic tasks did not directly influence their intention to take future online courses. Instead, the influence of performance proficiency on online learning continuance intention was mediated through the factor of satisfaction. In addition, satisfaction was found to have a significantly direct impact on online learning continuance intention, suggesting that when students taking online courses are satisfied with their online learning experience, the likelihood for them to continue taking other online courses is higher

Numerical earthquake models of the 2013 Nantou, Taiwan, earthquake series: Characteristics of source rupture processes, strong ground motions and their tectonic implication

On 27 March and 2 June 2013, two large earthquakes with magnitudes of ML 6.2 and ML 6.5, named the Nantou earthquake series, struck central Taiwan. These two events were located at depths of 15–20 km, which implied that the mid-crust of central Taiwan is an active seismogenic area even though the subsurface structures have not been well established. To determine the origins of the Nantou earthquake series, we investigated both the rupture processes and seismic wave propagations by employing inverse and forward numerical simulation techniques. Source inversion results indicated that one event ruptured from middle to shallow crust in the northwest direction, while the other ruptured towards the southwest. Simulations of 3-D wave propagation showed that the rupture characteristics of the two events result in distinct directivity effects with different amplified shaking patterns. From the results of numerical earthquake modeling, we deduced that the occurrence of the Nantou earthquake series may be related to stress release from the easternmost edge of a preexistent strong basement in central Taiwan

A strong-motion hot spot of the 2016 Meinong, Taiwan, earthquake (M_w = 6.4)

Despite a moderate magnitude, M_w = 6.4, the 5 February 2016 Meinong, Taiwan, earthquake caused significant damage in Tainan City and the surrounding areas. Several seismograms display an impulsive S-wave velocity pulse with an amplitude of about 1 m s-1, which is similar to large S-wave pulses recorded for the past several larger damaging earthquakes, such as the 1995 Kobe, Japan, earthquake (M_w = 6.9) and the 1994 Northridge, California, earthquake (M_w = 6.7). The observed PGV in the Tainan area is about 10 times larger than the median PGV of M_w = 6.4 crustal earthquakes in Taiwan. We investigate the cause of the localized strong ground motions. The peak-to-peak ground-motion displacement at the basin sites near Tainan is about 35 times larger than that at a mountain site with a similar epicentral distance. At some frequency bands (0.9 - 1.1 Hz), the amplitude ratio is as large as 200. Using the focal mechanism of this earthquake, typical “soft” and “hard” crustal structures, and directivity inferred from the observed waveforms and the slip distribution, we show that the combined effect yields an amplitude ratio of 17 to 34. The larger amplitude ratios at higher frequency bands can be probably due to the effects of complex 3-D basin structures. The result indicates that even from a moderate event, if these effects simultaneously work together toward amplifying ground motions, the extremely large ground motions as observed in Tainan can occur. Such occurrences should be taken into consideration in hazard mitigation measures in the place with frequent moderate earthquakes

Effect of music interventions on anxiety during labor: a systematic review and meta-analysis of randomized controlled trials

Background Anxiety is commonly experienced during the delivery process and has shown to have adverse effects on maternal and infant health outcomes. Music interventions tend to reduce the effects of anxiety in diverse populations, are low cost, are easily accessible, and have high acceptability. The aim of this review and meta-analysis was to assess the effectiveness of music interventions in reducing anxiety levels among women during labor. Methods Seven databases from inception to the end of December, 2018, without any language or time restriction including Embase, PubMed, the Cochrane Library, the Cumulative Index to Nursing and Allied Health, PsycINFO, Airiti Library, and PerioPath: Index to Taiwan Periodical Literature were searched using key terms related to pregnancy, anxiety, and music. Randomized controlled trials that assessed the effect of music during labor and measured anxiety levels as an outcome were included. Meta-analyses were conducted to assess anxiety reduction following a music intervention compared to that after placebo treatment. Results A total of 14 studies that investigated a total of 1,310 participants were included in this review. The meta-analyses indicated that those in the intervention group had a significant decrease in anxiety scores (standardized mean difference = −2.40, 95% confidence interval (CI) [−3.29 to −1.52], p < 0.001; I2 = 97.66%), heart rate (HR) (difference in means = −3.04 beats/min, 95% CI [−4.79 to −1.29] beats/min, p = 0.001; I2 = 0.00%), systolic blood pressure (SBP) (difference in means = −3.71 mmHg, 95% CI [−7.07 to −0.35] mmHg, p = 0.031; I2 = 58.47%), and diastolic blood pressure (DBP) (difference in means = −3.54 mmHg, 95% CI [−5.27 to −1.81] mmHg, p < 0.001; I2 = 0.00%) as compared to the women in the control group. Conclusions Music interventions may decrease anxiety scores and physiological indexes related to anxiety (HR, SBP, and DBP). Music interventions may be a good non-pharmacological approach for decreasing anxiety levels during labor
