Developing an integrated e-learning culture: a model grounded in the Australian Army experience

Newton, Diane Unknown Date (has links)
Understanding the influences on e-learning effectiveness in workplaces is a necessary, but contentious task. The transfer of knowledge about e-learning from higher education to workplace situations has resulted in discursive tensions between expectations and practice. Measurement of the aspects of e-learning effectiveness is often discussed in the literature in terms of discrete economic, pedagogical and technological criteria. Few studies have investigated e-learning use in terms of the complexity of factors in a workplace environment and there is a scarcity of relevant substantive models of e-learning effectiveness factors in workplace contexts. This study aimed to improve understanding of the factors influencing e-learning effectiveness, particularly in large, dispersed workplaces and to develop a model based on the understanding of these factors. This study represents the first external research into the Australian Army’s e-learning projects. The Army was selected as a large, dispersed workplace organisation with ten years experience in designing and using multimedia rich CD-ROM learning materials. The Army had undertaken trialing and evaluation of its e-learning courses prior to providing substantial infrastructure for implementation in training centres. These evaluations indicated e-learning effectiveness in terms of training efficiencies and learning outcomes that at least matched traditional face-to-face classroom instruction. That is, that e-learning fitted with the training requirements. The study was aimed at the understanding of how the Army’s workplace environment was influencing the effectiveness of e-learning courses from multiple perspectives.Using an inductive Grounded Theory approach provided an established analytical method for developing a substantive model. While the field-based research was limited to a single organisation, it included multiple sites across Australia and a cross-section of e-learning activities and respondents throughout the organisational hierarchy. The main data source was 101 open-ended interviews conducted with respondents at Army bases or by phone. Where interviewing was not possible due to Army operational concerns, questionnaires were used (129 responses). Other data sources included Army documents and the researcher’s observations and participation in e-learning classes.While the Army’s internal evaluation processes had justified the adoption of e-learning courses, it was evident in the study that the interaction of factors within the Army’s culture was influencing perceptions and experiences of e-learning effectiveness. An Integrated E-learning Culture Model (IECM) based on the analysis of stakeholder perspectives in the Army is presented. The IECM is based on the four factors that emerged as influencing e-learning effectiveness, which were organisational priorities, the learning environment, the instructor’s role and learners’ needs. The main concern for respondents was to manage tensions associated with these four factors by integrating e-learning into the organisational culture. That is, e-learning effectiveness was discussed in terms of a process of alignment of the e-learning culture with the organisational culture.Comparison of the IECM with some empirical studies of e-learning use in other large, dispersed workplaces indicates its relevance outside the Army context. An E-learning Comparative Alignment Framework (ECAF) for using the IECM in other research was developed in this study. Further comparison of the ECAF with alignment theories from related research disciplines suggests areas for further theoretical research. This thesis proposes that by adopting the perspective that e-learning environments are not value-free, it is possible to identify and align the competing priorities and discourses that influence how e-learning effectiveness is constructed and experienced in an organisation.

Middle School Teachers' Technology Integration

Noonan, Andrea 01 January 2018 (has links)
Although school districts have invested heavily in technology for teachers and students, the problem of inconsistent technology integration permeated a local school district. In order to create a 21st century learning environment for students, teachers must integrate technology with curriculum and evidence-based teaching practices. The purpose of this case study was to investigate current middle school teachers' technology integration in a suburban school district in North Dakota, Midwest Public Schools (pseudonym). Technological Pedagogical Content Knowledge (TPACK) was used as a conceptual framework to guide the study. This study focused on exploration of current teacher practice in regard to technology integration and the perceived support they currently receive to do so. A case study research design was used, and data collection included interviews and classroom observations of 10 middle school teachers to determine current technology integration practices and explore the barriers for integration and teachers' perceived support in this endeavor. The 10 participants were chosen based on content area, grade level, and years of experience. The data were analyzed using thematic coding followed by an open coding process based on the TPACK framework constructs. Teachers are using technology in their instruction at varying levels. Overall, the case showed a strong indication of TCK and lower results in the area of student technology use. The results provided information for administrators in the district regarding additional training for teachers based on their current technology integration and perceived barriers of implementation in the classroom. Social change implications for this study involve an increased awareness of technology integration for teachers and administrators. Classroom teachers in this local district as well as districts across the nation could benefit from improved practice using technology to be able to learn and work in the complex school and work environments.

Primary Teachers' Perspectives on iPad Integration: Barriers, Challenges, and Successes

Campbell, Richard Cory 01 January 2016 (has links)
Despite the rapid expansion of mobile technologies in K-12 schools, recent research has shown that many teachers are ill prepared to take advantage of these new tools. This study was designed to address the problem of lack of effective iPad integration in primary classrooms at an international school in South Korea. The purpose of this case study was to examine primary teachers' perceptions of the implementation of an iPad initiative begun in 2012. Framed by Koehler and Mishra's technological pedagogical content knowledge model (TPACK), the study was guided by research questions that involved teachers' perceptions of the barriers, challenges, and successes regarding iPad implementation in the primary classroom. A purposeful sample of 5 K-2 teachers who use iPads in the classroom was chosen. The case study design entailed semi-structured interviews, classroom observations of each participant, and examination of teachers' lesson plans. Data were coded and analyzed using inductive analysis based on components of a conceptual logic model. Credibility and trustworthiness were ensured through member checking and triangulation of data. Results showed lack of experience, collegial support, and iPad-specific training as barriers and future preparation for teachers as a challenge. Successes were demonstrated through formative assessments and digital portfolios. The resulting project was a comprehensive professional development plan to provide primary teachers with the knowledge and skills to implement technology in the classroom and ongoing support to develop a professional technology learning network. In terms of broad social change, this research and project might provide insight to better prepare educators to make the best use of integrated learning technologies for efficient and effective teaching and learning in classrooms.

Teaching slope of a line using the graphing calculator as a tool for discovery learning

Nichols, Fiona Costello 01 January 2012 (has links) (PDF)
Discovery learning is one of the instructional strategies sometimes used to teach Algebra I. However, little research is available that includes investigation of the effects of incorporating the graphing calculator technology with discovery learning. This study was initiated to investigate two instructional approaches for teaching slope of a line in Algebra I. One approach involves the graphing calculator as a tool in a discovery learning setting. The second approach involves using the graphing calculator to reinforce traditional instruction. An urban public school division located in southeastern Virginia was the site for this investigation. Two Algebra I classes from each of two middle schools and two Algebra I classes from each of three high schools were involved in this study. The experimental groups completed a discovery learning activity, while the control groups used traditional instruction. This study is an investigation of whether there was a difference in student achievement in slope of a line when one discovery learning activity was completed prior to formal instruction. It was concluded that student achievement did not increase with the inclusion of one discovery learning based activity. Further study is needed to evaluate if discovery learning is effective if utilized throughout the unit on slope of a line, if additional professional development focused on discovery learning is necessary, or if a series of discovery learning activities would increase student achievement.

A Q-methodology study of adult English language learners' perceptions of audience response systems (clickers) as communication aides

Rodriguez, Lisa Ann 01 January 2010 (has links)
This study explored the perceptions of adult English language learners about the use of audience response systems (clickers) to facilitate communication in a classroom environment. In the early stages of second language acquisition, learners' receptive capabilities surpass expressive capabilities, often rendering them silent in their second language. Educational strategies and tools may be available to help English language learners communicate more effectively by enabling them to demonstrate their knowledge and express their opinions nonverbally. Many studies have been conducted with clickers, but none were found pertaining to adult English language learners. Second language acquisition theory provided the theoretical base for this research. In this Q-methodological study, adult English language learners enrolled in a computer skills course ranked statements about using clickers according to how closely they align with their personal perceptions. Factor analysis was performed to identify commonalities and patterns in perceptions. The findings support the view that second language acquisition theory influences how technology tools are perceived by English language learners. Adults with lower English language proficiency levels perceived the anonymity provided by clickers to be beneficial. Participants with beginning to intermediate levels of English proficiency perceived the clickers to be more valuable for communication than did those with lower levels of English proficiency. Results of this study may affect positive social change by leading to more effective instructional and assessment practices for adult English language learners and by fostering research into the viability of educational technology communication tools with all English language learners.

Interactive Technology and Engaging Learners in the Mathematics Classroom

Camara, Phyllis 01 January 2011 (has links)
The Program for International Assessment tested students in mathematics from 41 countries and found that students in the United States ranked in the lowest percentile. This struggle with math among youth in the United States prompted this quasi-experimental quantitative study about using interactive technology to engage and motivate 9th grade students in an Algebra classroom. The theoretical basis of this study was a constructivist perspective, using the Piagetian concept of action as an intellect builder. A convenience sample of 76 students was divided into 4 groups: Group 1, the control group, used no technology and consisted of 21 students; Group 2 used the TI Nspires calculators and consisted of 17 students; Group 3 used the TI Nspire calculators with the TI Navigator and consisted of 20 students; and Group 4 used the TI Nspire calculators, the TI Navigator, and the clickers. The participants were given 45 instructional classes that covered a 9-week period. All groups took the Motivated Strategy for Learning Questionnaire (MSLQ) and the State of Texas Assessment of Academic Readiness test (STAAR) before and after the treatment of interactive technologies. A paired t test and a factorial repeated ANOVA were conducted, revealing no significant effect for the MSLQ based on the use of technology. However, the use of technology with the STAAR did show a significant difference in test scores for 2 treatment groups: Group 3, which used the calculator and the TI navigator; and Group 4, which used the calculator, the TI navigator, and the clickers. These results support the use of additional technology that is needed in the mathematics classroom to support the use of the calculators.
