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.

The present work examines the use of background music (BM) to facilitate learning. This dissertation includes three independent, yet interrelated studies that synthesized scholarship to characterize the methods, and BM characteristics that have been manipulated in primary research, to identify trends, patterns and gaps. Then, it integrates findings of experimental studies that reported influences of music on cognitive performance to inform future research and theory. Lastly, this dissertation reports a design-based research study aimed at improving an online learning environment with the use of BM to enhance students' motivation, engagement and knowledge retention.

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.

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.

Technology is a learning and teaching tool that enhances students' communication, innovation, and critical thinking skills, also known as 21st century learning goals. Successfully using technology in the classroom to promote these learning goals, however, has presented some challenges for teachers. While research has identified a variety of obstacles that prevent teachers from using technology, little investigation has been done on the barriers of technology integration as related to 21st century learning goals. The purpose of this qualitative case study was to examine teachers' perceived barriers to technology integration related to 21 st century learning goals. Guided by a conceptual framework that posited a relationship between the digital divide and students' learning, the research questions in this study investigated teachers' perceived barriers to technology integration. Twenty-three elementary school teachers from a local school district completed an open-ended questionnaire, and 6 of the teachers participated in interviews to gather data to investigate the problem. Coding using the constant comparative analysis was the primary strategy for data analysis. Findings indicated that teachers perceived a lack of technology resources to allow students individual access to technology as the primary obstacle to technology integration. These findings led to the implementation of a program for to allow students to bring their own technology to school. Social change resulting from this study could include a transformation of teachers' instructional practices and student learning; this transformation might, in turn, affect student achievement of 21st century learning goals.

Increasingly, educational reform efforts are turning towards data-driven decision making strategies to help teachers improve instruction through skills-based instruction/content that is both measurable and aligned to common rigorous standards, such as the Common Core State Standards (CCSS). Examining the impact of a formative online assessment system on a summative measurement of student achievement may provide evidence that data-driven instructional platforms can impact student achievement and learning outcomes. Guided by the theoretical frameworks of Vygotsky and Dewey, along with the concepts of multiple intelligence, constructivism, and mastery learning, this study examined the relationship between student scores from an online formative assessment administered quarterly and an end-of-year summative evaluation. A stepwise multiple regression analyzed the predictive power of the iReady formative assessment program towards archived SAT-10 reading and mathematics data among Grades 1-4 students, before and after the iReady program was implemented (N = 339). The results showed a significant relationship between the iReady program and SAT-10, explaining 11.6% of the variance in SAT-10 scores. The study's intended audience is educators, school districts, and policy makers who are using the achievement data produced by formative assessments to improve results on measures of academic achievement, leading to positive social change.

Stakeholders in a midsized rural high school district were concerned that faculty failure to integrate educational technologies into instruction was adversely affecting student performance as measured by recent state mandated test scores. The purpose of this study was to determine if relationships existed between faculty age, gender, tenure, and overall attitude toward technology, and the implementation of technology into classroom instruction. Dewey's and Knowles' theories of adult learning were used as theoretical frameworks because they emphasize the practical application of knowledge in the transfer of learning. The research design was a one-time cross-sectional survey of teachers within the district. The data were collected using the Levels of Technology Implementation survey extended to include 5 additional questions about attitude towards technology developed using existing literature and consultation with experts. The convenience sample was comprised of 103 volunteer respondents at 3 midsized rural high schools. Analysis of the data utilized Pearson's correlation coefficients, independent samples t-tests, ANOVAs, and ANCOVAs. Findings indicated that technology implementation in classroom instruction for this group is generally deficient. No significant relationships between faculty age, gender, and tenure and technology implementation existed, but attitude toward technology proved to be a significant factor for increased technology implementation into classroom instruction. These findings led to the creation of a professional development program to increase the impact of technology on the transfer of learning. Increasing faculty expertise in implementing instructional technology into classroom instruction will lead to greater innovation in the classroom and improved student outcomes.
