Middle School Mathematics Teachers Learning to Teach with Calculators and Computers

This paper reports the results of a project in which experienced middle grades mathematics teachers immersed themselves in calculator and computer use for both doing and teaching mathematics and prepared themselves as leaders for communicating their knowledge to colleagues. Project evaluation included interviews with participants at the beginning and end of the project and evaluation forms completed at the end of the project. Pre-interviews indicated that virtually all of the participants had no experience using technology to teach mathematics. Many felt that technology was not likely to be as effective in helping students learn mathematics as other teaching techniques. Post-interviews indicated that all teachers were confident of their abilities to use some technologies in teaching mathematics. They acknowledged that technology was useful in developing conceptual understanding and that their role was to guide this conceptual development. The differences in participants' perceptions about how the project affected them yielded suggestions for future inservice efforts about technology.     

Middle School Mathematics Teachers Learning to Teach With Calculators and Computers

This paper reports the results of a project in which experienced middle grades mathematics teachers immersed themselves in calculator and computer use for both doing and teaching mathematics and prepared themselves as leaders for communicating their knowledge to colleagues. Project evaluation included formal observation of students while they used technology in learning mathematics. Classroom observation data suggested that computers hold somewhat more attraction for students than calculators. Overall, students in all 13 classes, independent of the type of technology used, were observed to be off-task 3% of the time. These data suggested a classroom environment in which the teacher worked hard to engage students in mathematical activity. The fact that students were observed off-task so little is encouraging. The difference in off-task behaviors for calculators versus computers suggests that different technologies will indeed have different effects on students. It appears that the introduction of technologies in classrooms altered the ways teachers taught.     

Stepping into iSMART: Understanding Science–Mathematics Integration for Middle School Science and Mathematics Teachers

This paper is based on an online graduate program for middle school science and mathematics teachers in Texas titled Integration of Science, Mathematics and Reflective Teaching (iSMART). Launching the program for its first cohort in fall 2010, the authors attempted to answer the following two questions in this paper: (a) How do the members of the iSMART design team and the first cohort of teacher participants define science and mathematics integration with similar and different emphases? and (b) How would these definitions and concerns impact the ongoing design of the program? The iSMART design team members and the participating cohort teachers had a shared view regarding the importance of integration and its possible impact on student motivation. The findings also revealed that the two groups showed some different points of emphasis in their definitions of integration. These issues will be addressed in the ongoing design of the program in the following three areas: (a) design of the second summer meeting activities, (b) greater emphasis on teacher as researcher and action research, and (c) administrative support for teacher collaboration.     

Problem Posing: A Neglected Component in Mathematics Courses for Prospective Elementary and Middle School Teachers

The purpose of this article is to describe a scheme which is designed to guide the prospective teacher beyond the point of proficiency as a student solving given problems. By experiencing several stages of inquiry, the scheme provides a mechanism where by the prospective teacher advances toward assuming the role of a teacher posing his or her own problems. Although the scheme has been developed within the context of a standard mathematics course for preservice teachers, the ideas set forth are equally appropriate for incorporation within a science course for prospective teachers.     

Applying NAEP to Improve Mathematics Content and Methods Courses for Preservice Elementary and Middle School Teachers

This study explored how mathematics content and methods courses for preservice elementary and middle school teachers could be improved through the integration of a set of instructional materials based on the National Assessment of Educational Progress (NAEP). A set of eight instructional modules was developed and tested. The study involved 7 university instructors and 542 preservice teachers (PSTs) from three different universities. A quasi‐experimental nonequivalent groups design was used for this study in which the following data sources were collected and analyzed. Three versions of a Learning Mathematics for Teaching test were given to assess PSTs‘ mathematical content knowledge for teaching: (a) Elementary Number Concepts and Operations—Content Knowledge; (b) Elementary Geometry—Content Knowledge; and (c) Middle School Number Concepts and Operations—Content Knowledge. In addition, the Mathematics Teacher Efficacy Beliefs Instrument was given to assess PSTs’ teacher efficacy beliefs. Test results were analyzed using paired samples t‐tests. Findings suggest that use of instructional materials, based on NAEP, with PSTs results in increases in their mathematical content knowledge for teaching and in their teaching efficacy beliefs.     

Controlling Choice: Teachers,Students, and Manipulatives in Mathematics Classrooms

This research study examines the instructional practices of 10 middle grades teachers related to their use of manipulatives in teaching mathematics and their control of mathematics tools during instruction. Through 40 observations of teaching, 30 interviews, and an examination of 67 written documents (including teachers' plans and records), profiles were developed that describe how teachers used and controlled manipulatives during instruction. Results showed that teachers used a variety of manipulatives and other mathematics tools over the course of the year‐long study. Teachers reported using a mathematics tool (manipulative, calculator, or measuring device) in 70% of their lessons, and this self‐report was verified by observations in which teachers used mathematics tools in 68% of their lessons. During a 3‐ to 4‐month period of “free access,” in which students had some measure of control in their selection and use of the mathematics tools, the students used manipulatives spontaneously and selectively. During free access, teachers exhibited various behaviors, including posting lists of items on containers, assigning group leaders to manage tools, and negotiating the control of the mathematics tools during instruction.     

Secondary Mathematics Modeling: Issues and Challenges

Mathematical modeling plays a prominent role in the mathematics reform effort. For example, modeling, as incorporated in the curriculum recommendations of the National Council of Teachers of Mathematics, forms the basts of classroom activities developed by groups such as the Consortium for Mathematics and Its Applications and the Systemic Initiative for Montana Mathematics and Science. Modeling is also a topic of workshop and conference presentations at the state, regional, and national levels. Recommendations regarding the future of mathematics education indicate that the emphasis on modeling will continue to grow. In this article, an overview of mathematical modeling is presented and the reasons underlying the current interest in this topic are discussed. The article also identifies several practical issues that are raised by the use of modeling in secondary classrooms.     

Knowing and Teaching Middle School Mathematics: A Professional Development Course for In‐Service Teachers

This article describes a professional development course intended to improve the content understanding of middle school mathematics teachers. The design of the course included three professional learning strategies: problem solving, examination of student thinking, and discussion of research. The concepts studied in the course included multi‐digit subtraction, multi‐digit multiplication, operations with fractions, and concepts of area and perimeter. Results from pre‐ and post‐tests administered to the nineteen participants indicate a significant increase in the mean score for each concept and document growth in the teachers' content understanding. In particular, their solutions moved from primarily procedural to more conceptual. Responses to an open‐ended survey indicate other important aspects of the professional development. Examples of teachers' work and comments are included.     

The Impact of Participation in an Ancillary Science and Mathematics Program (SEMAA) on Engagement Rates of Middle School Students in Regular Mathematics Classrooms

The purpose of this study was to investigate the impact of participation in a federally sponsored, short‐term, cocurricular, mathematics and science program (Science Engineering Mathematics Aerospace Academy, SEMAA) on the engagement rates of sixth‐ and seventh‐grade students in public school mathematics classes. Engagement was measured with the Student Record of Behavior at three time intervals. Results of a 22.3 ANOVA investigating three main effects (participation, level of access to technology, and time) and their primary and secondary interactions reflected no discernable impact of the SEMAA program on student engagement rates. Ancillary programs designed to compensate for deficiencies in daily instructional programs may represent engagement opportunities vastly different from the daily instructional programs they support. Consequently, ancillary programs may not impact engagement in regular classrooms and subsequently improve achievement outcomes, especially when implemented in low‐performing schools and high‐stakes accountability settings. Recommendations include alignment of ancillary programs with the daily instructional programs they support and with ongoing professional development activities and that further study include broadened samples, settings, and variables.     

Including Curriculum Focus in Mathematics Professional Development for Middle‐School Mathematics Teachers

This paper examines professional development workshops focused on Connected Math, a particular curriculum utilized or being considered by the middle‐school mathematics teachers involved in the study. The hope was that as teachers better understood the curriculum used in their classrooms, i.e., Connected Math, they would simultaneously deepen their own understanding of the corresponding mathematics content. By focusing on the curriculum materials and the student thought process, teachers would be better able to recognize and examine common student misunderstandings of mathematical content and develop pedagogically sound practices, thus improving their own pedagogical content knowledge. Pre‐ and post‐mathematics content knowledge assessments indicated that engaging middle‐school teachers in the curriculum materials using pedagogy that can be used with their middle‐school students not only solidified teachers' familiarity with such strategies, but also contributed to their understanding of the mathematics content.
