Book Description
The concept of function is critical to the study of mathematics since it cuts across virtually all areas of mathematics and has a robust ability to provide meaningful representations of complex situations in the real world. Studies however, have shown that students have difficulty in shifting among representations of a function. Other studies have shown that graphing calculators can improve students' conceptual understanding of functions by allowing them to explore the various representations. This book extends the research base by considering how teachers' beliefs about graphing calculators may influence their use of multiple representations. The book also examines how the nature of classroom dynamics - teacher directed lessons versus lessons involving student exploration - influences the role of the graphing calculator and subsequently the exploration of multiple representations. Results reported here should benefit various groups involved with teacher preparation including pre-service teacher educators, professional development providers for in-service teachers and curriculum developers who create materials that incorporate technology.

Book Description
Graphing calculators have been used in education since 1986, but there is no consensus as to how, or if, they should be used. The National Council of Teachers of Mathematics and the National Research Council promote their use, and ample research supports the positive benefits of their use, but not all teachers share this view. Also, rural schools face obstacles that may hinder them from implementing technology. The purpose of this study is to determine how graphing calculators are used in mathematics instruction of high schools in western Kansas, a rural region of the state. In addition to exploring the introduction level of graphing calculators, the frequency of their use, and classes in which they are used, this study also investigated the beliefs of high school mathematics teachers as related to teaching mathematics and the use of graphing calculators. Data were collected through surveys, interviews, and observations of classroom teaching. Results indicate that graphing calculators are allowed or required in almost all of the high schools of this region, and almost all teachers have had some experience using them in their classrooms. Student access to graphing calculators depends more on the level of mathematics taken in high school than on the high school attended; graphing calculator calculators are allowed or required more often in higher-level classes than in lower-level classes. Teachers believe that graphing calculators enhance student learning because of the visual representation that the calculators provide, but their teaching styles have not changed much because of graphing calculators. Teachers use graphing calculators as an extension of their existing teaching style. In addition, nearly all of the teachers who were observed and classified as non-rule-based based on their survey utilized primarily rule-based teaching methods.

Book Description
This study investigated the beliefs and classroom practices of four teachers who had used graphing calculators in their teaching for a minimum of three years prior to the study and at least one prior year in the teaching of second year algebra. The persistence criteria, prior experience utilizing graphing calculators in their teaching, was designed to provide an investigation of established beliefs and practices. A case study approach involving detailed examination of the four teachers was used. The data collected and analyzed included interviews, observational fieldnotes, videotapes of classroom observations, and documents. Upon the completion of data collection detailed descriptions of the beliefs and classroom practices of the individual teachers were created. Additional analysis included exploration of the consistencies and discrepancies within individual teacher's beliefs and practices, exploration of the consistencies among teachers, and comparisons of teachers' professed beliefs and demonstrated practices to the constructivist theory and visions for the use of graphing calculators. A high degree of consistency was found between the teachers' beliefs and classroom practices, both when graphing calculators were in use and when they were not. Particularly notable were the consistency between the espoused belief in the importance of assisting students in making connections and the observed emphasis on connections between concepts being presented and concepts previously explored. It was found that teachers' experiences outside of the classroom, especially interaction with other teachers, played a significant role in the process of bringing beliefs and practices into agreement. These experiences served as factors in development of beliefs and practices and as stimulators for reflection, the central element in the process of developing an integrated structure of beliefs and practices. The use of graphing calculators was found to focus on learning to use the tool to do mathematics and not as a tool to learn mathematics. While the focus on using the graphing calculator as a tool to do mathematics was not consistent with the constructivist approach to teaching and the visions for the use of graphing calculators, it was consistent with the teachers' view of algebra as the foundation for the study of higher mathematics.

Book Description
The research question addressed in this project was: how can I teach students to effectively use their graphing calculators in their high school math classes and on the math section of the ACT? First, the calculator skills that students need both in their math classes and on the ACT were determined. Then a curriculum was built to help teach students these skills. Finally the curriculum was used in teaching several students these skills.

Book Description
Nowadays, technology plays a fundamental role in education, in general, and in mathematics education in particular. The graphing calculator has been an important technological tool in mathematics classrooms since its invention and introduction in 1985 by Casio. As graphing calculators provided so many uses, their contribution to the teaching and learning process has been investigated by many researchers who have shown the use of such technology can have a significant effect on improving mathematics teaching and learning. Investigating the impact of graphing calculators on student learning is important. It is also essential to research teachers' perspectives on how using graphing calculators in mathematics determines how such use affects their teaching and learning. However, there are few studies on this issue. Therefore, this dissertation study may fill the gap in the literature in terms of examining high school mathematics teachers' perspectives when they teach a precalculus course with technology integrated in the curriculum materials. In this study, I analyzed eleven teachers' perspectives about using graphing calculator technology in a precalculus course, titled Functions, Statistics, and Trigonometry (FST). This study was a descriptive intrinsic case study in which I analyzed teachers' perspectives about how they use graphing calculators in the FST course, specifically about their teaching and students' learning with available graphing calculator technology. Additionally, I explored teachers' perspectives about the issues they face when using the available technology and for what topics teachers frequently used it. I used mixed methods to examine eleven mathematics teachers' perspectives about their teaching, students' learning, and issues that arise when they use graphing calculator technology.

Book Description
This study investigated teachers' conceptions of mathematics and their teaching practices with respect to the use of graphing calculators in their mathematics classrooms. Case studies on three teacher participants were developed using quantitative and qualitative data that consisted of self-assessments on beliefs in mathematics, observations, surveys on professional and personal technology use, and semi-structured interviews. All three teachers viewed mathematics as a dynamic field, emphasized understanding concepts as opposed to mechanical procedures, and preferred the construction and understanding of the concept over the memorization of procedures. All three teachers were willing to use graphing calculators in the mathematics classroom and all three had a similar goal of attempting to use the graphing calculators to eliminate mechanical processing time and enhance their students' ability to construct their own learning. The evidence from the study suggests that these teacher's practices, with respect to the use of graphing calculators in the mathematics classroom, are influenced by how proficient their students are at using this technology and how accessible the technology is. There were five major findings from the study: (1) if the mechanics of operating a graphing calculator involve at least as much mental effort as the mechanics involved in pencil and paper work, then using the graphing calculator will not free up students so that they can concentrate on constructing their own knowledge and understanding of mathematical concepts or solving more complex problems; (2) when mechanical operating issues are overcome, introducing graphing calculators into the mathematics classroom aids teachers in helping students construct their own mathematical knowledge by allowing all students to begin at a common starting point; (3) to obtain the full benefits of having students learn with the graphing calculators in the mathematics classroom, teachers must require students to use the graphing calculators when they are being evaluated; (4) teachers will determine for themselves where graphing calculators can be most appropriately used in the curriculum; and (5) teachers require strategies that will allow them to successfully deal with managing the day-to-day difficulties involved in using technological instruments such as the graphing calculator in the classroom. Implications for future study include how we can help those teachers inexperienced with the use of technology to incorporate the use of technology in their classrooms, how we need to address the need for consistent teaching practices throughout the intermediate, secondary and post-secondary levels, and how future case studies can be coded to reflect more precisely the language used by teachers to question students in the classroom. Suggestions for educators to consider when using graphing calculators in the mathematics classroom are given at the end of the study.

Book Description
The need exists for methods courses to address the pedagogy issues of using graphing calculators. There needs to be a teacher candidate forum to examine their pedagogical perspectives on using graphing calculators in teaching, to explore when and how to use graphing calculators in the classroom, and to provide opportunities to practice teaching with graphing calculators. A recent study by Lyublinskaya, Donoghue and Zhou (2006) tracked the effects of such training on elementary and secondary pre-service teachers in methods classes for math and science. All students were divided into two groups. The first group consisted of undergraduate and graduate students preparing to teach secondary science and math, and who were enrolled in math and science methods courses. The second group consisted of undergraduate students preparing to teach in the elementary schools and who were enrolled in science methods courses. This study concludes that the perspectives and attitudes of pre-service teachers in their methods courses strongly depend on the intensity and length of experience they have with use of graphing calculators and calculator-based data collection devices (probe ware). The study also concludes that participants' confidence in the use of technology is somewhat independent of their perspective.

Book Description
Graphing calculators are mainstay in the U.S. high school mathematics curriculum and because of that considerable research has been done on the effect of graphing calculators in the math classroom. Until recently most of the research on graphing calculator use in mathematics education has either been quantitative in nature, focusing on student achievement and attitude, or qualitative focusing on the teaching and learning of a particular mathematical topic (Choi-Koh, 2003; Ellington, 2003; Forester & Mueller, 2002; Smith & Shotsberger, 1997, for example). In addition, there is a growing body of research on how students are adapting graphing calculator technology to their mathematical learning (Artigue, 2002; Drijvers, 2000; Guinn and Trouche, 1999). However, none of this work addresses how students use the graphing calculator when they are working in independent situations or their perceptions of how the graphing calculator impacts their mathematical experience. My work aims to attend to this gap in the research. This dissertation reports on a mixed methods study with data consisting of survey data (n = 111) and in-depth interview data compiled from six case studies. The case study students participated in a task based interview and a stimulated response reflection interview. Particular attention was paid to both the affective and mathematical aspects of graphing calculator use. The data indicates that AP Calculus students value the ability to change the cognitive demand of tasks, the ability to engage in mathematical play, to check their written solutions, and to manage time effectively when doing mathematics. All of the students reported that using the graphing calculator in each of these ways provides them with both a mathematical and affective pay-off. Most surprising is that the ways in which the students value using their graphing calculators to solve problems does not coincide with their perceptions of what it means to 'do math' in a school setting. This result suggests that in the continuing discussion of how and if graphing calculators should be incorporated into school mathematics and assessment it is important to address this inconsistency.
