Drivers and inhibitors of SaaS adoption in Korea

The concept of software as a service (SaaS) has received considerable attention in recent years, and an increasing number of countries have consequently promoted the SaaS market. However, those countries without mature SaaS markets have experienced many SaaS-related problems. To facilitate SaaS adoption, we first analyzed Korea's newly established SaaS market. We then employed a method based on the two-factor theory in order to classify the SaaS market into adoption-driving and adoption-inhibiting areas. From the adoption-driving area perspective, the results of the method demonstrate the validity of the consumerization phenomenon and the PEST analysis. Customer factors in the consumerization phenomenon and economic factors in the PEST analysis were the most important drivers of SaaS adoption. From the adoption-inhibiting area perspective, customer factors as well as supplier and environment factors inhibited SaaS adoption; according to the PEST analysis, social, economic and political factors inhibited SaaS adoption. These results have important implications for Asian countries with newly established SaaS markets, including Australia, China and Singapore.     

Phases and patterns of group development in virtual learning teams

With the advancement of Internet communication technologies, distributed work groups have great potential for remote collaboration and use of collective knowledge. Adopting the Complex Adaptive System (CAS) perspective (McGrath, Arrow, & Berdhal, Personal Soc Psychol Rev 4 (2000) 95), which views virtual learning teams as an adaptive and self-organizing entity, this study examined group development processes of seven intact virtual learning teams over 12 weeks using the multiple case study design. Content analysis revealed seven temporal group development phases: orientation, scheduling, exploration, work and decision, progress check and evaluation, refinement and formatting, and termination. The development pattern of each virtual learning team could be described as either Linear Progression, a straight movement through those phases, or Adaptive Progression, a backward movement to a previous phase for adaptation before proceeding. We also identify the factors that caused each team to develop in one way or the other and conclude with the implications of conceptualizing virtual teams as a CAS.     

Improving caregivers’ confidence with the Powerful Tools for Caregivers program

ABSTRACT

The Powerful Tools for Caregivers (PTC) program is designed to help caregivers develop skills to improve their self-efficacy in caregiving. To demonstrate the effectiveness of the PTC program in Boise, Idaho, the program’s pre-survey (n = 277), end-of-program survey (n = 131), and 6-month follow-up post-survey data (n = 100) collected between 2011 and 2017 were analyzed in this study. The end-of-program survey data indicated that caregivers viewed the quality of the program to be excellent and that all of them felt more confident as a caregiver. Factor analysis and reliability testing on the pre-survey data confirmed that seven questions included in the pre- and 6-month follow-up post-survey instruments reliably measured a single factor named as caregiver confidence. A paired samples t-test on 76 complete sets of pre- and 6-month follow-up post-survey data on the seven questions revealed that caregivers improved their confidence in caregiving to a statistically significant level (p < .001, d = 45). Additional paired samples t-tests on each of the seven questions with the Bonferroni correction showed statistically significant improvements in three areas: making tough decisions (p < .001, d = .53), coping with emotions (p < .001, d = .54), and using stress-reducing activities (p < .007, d = .33). Caregivers experienced the greatest improvement in their confidence in making tough decisions. Despite these significant improvements, caregivers still struggled with finding ways to reduce stress and manage their emotions associated with caregiving as shown by the lowest pre- and 6-month follow-up post-survey scores. In addition to the study results, several considerations when synthesizing PTC research results are discussed.     

The Effect of a Collaborative Mentoring Program on Beginning Science Teachers' Inquiry-based Teaching Practice

This study investigated how a collaborative mentoring program influenced beginning science teachers' inquiry-based teaching and their reflection on practice. The one-year program consisted of five one-on-one mentoring meetings, weekly science education seminars, weekly mentoring group discussions, and self-evaluation activities. The participants were three beginning science teachers and three mentors at the middle school level (7–9th grades) in an urban area of South Korea. For each beginning teacher, five lessons were evaluated in terms of lesson design/implementation, procedural knowledge, and classroom culture by using the Reformed Teaching Observation Protocol. Five aspects of the beginning teachers' reflections were identified. This study showed that a collaborative mentoring program focusing on inquiry-based science teaching encouraged the beginning teachers to reflect on their own perceptions and teaching practice in terms of inquiry-based science teaching, which led to changes in their teaching practice. This study also highlighted the importance of collaborative interactions between the mentors and the beginning teachers during the mentoring process.     

Improving Preservice Middle Grades Science Teachers’ Understanding of the Nature of Science Using Three Instructional Approaches

The purpose of this study was to investigate changes in preservice teachers’ understanding of the nature of science (NOS) as a result of four activity-based interventions that represent three instructional approaches used in a middle grades science methods course. Ten participants’ understanding of NOS and their perceptions about the activity-based interventions were investigated. Data were collected using open-ended questionnaires and in-depth interviews before and after the interventions. Written artifacts and recorded group discussions were collected during the interventions. The results of this study showed that inclusion of various approaches to teaching NOS can contribute to developing preservice teachers’ understanding of NOS. The activities complemented each other in the teaching of the NOS components. In addition, the preservice teachers perceived that the four interventions were helpful in improving their understanding of NOS and in preparing them for future teaching.     

The relationship between university student learning outcomes and participation in social network services,social acceptance and attitude towards school life

Educators try to use social network services (SNSs) in their teaching because they are regarded as beneficial to student learning. However, little research to date has empirically investigated whether the use of an SNS increases university student learning outcomes. A total of 730 university students in the capital area of South Korea participated in the present study. Based on social learning theory, we developed a general structural model that included SNS participation (SP) as an exogenous variable and a range of endogenous variables: cognitive domain learning outcomes, affective domain learning outcomes, social domain learning outcomes, social acceptance (SA) and attitude towards university life (AT). The study results confirmed that the model adequately explained causal relationships between student learning outcomes and SA, AT and SP. SA was identified as a key variable because of its direct effect on learning outcomes. However, SP was considered more important because of its large indirect effects on all learning outcomes through both SA and AT.     

Affective and motivational factors of learning in online mathematics courses

We investigated what factors would be related to students' achievement in mathematics courses offered at a virtual high school. This was an attempt to understand why some succeed and some do not as well as to suggest what should be done to help with student success. Seventy‐two students responded to a self‐report survey on motivation (ie, self‐efficacy, intrinsic value), mathematics achievement emotions (ie, anxiety, anger, shame, hopelessness, boredom, enjoyment, pride), and cognitive processes (ie, cognitive strategy use, self‐regulation). A three‐step hierarchical multivariate regression was employed to examine which of the factors predict student achievement. Results showed that motivation accounted for approximately 13% of the variance in student achievement and self‐efficacy was the significant individual predictor of student achievement. However, when achievement emotions were added to the analysis, self‐efficacy failed to predict student achievement and emotions accounted for 37% of the variance in student achievement. Cognitive strategy use and self‐regulation did not explain any additional variance in the final scores. Findings are discussed and implications for future research and development are also suggested.     

Determining the Overall Impact of Interruptions During Online Testing

With an increase in the number of online tests, interruptions during testing due to unexpected technical issues seem unavoidable. For example, interruptions occurred during several recent state tests. When interruptions occur, it is important to determine the extent of their impact on the examinees’ scores. There is a lack of research on this topic due to the novelty of the problem. This article is an attempt to fill that void. Several methods, primarily based on propensity score matching, linear regression, and item response theory, were suggested to determine the overall impact of the interruptions on the examinees’ scores. A realistic simulation study shows that the suggested methods have satisfactory Type I error rate and power. Then the methods were applied to data from the Indiana Statewide Testing for Educational Progress‐Plus (ISTEP+) test that experienced interruptions in 2013. The results indicate that the interruptions did not have a significant overall impact on the student scores for the ISTEP+ test.
