appendix. The teachers were able to engage in the unit asstudents and were given time for reflection and discussion after each lesson within the unit. Teachers were first introduced to a multi-meter and were asked to measure the voltage ofseveral batteries. The unit had an inquiry-based focus; instead of telling the teachers how to use amulti-meter they were allowed to explore and discover how to measure voltage on their own. Asthe unit progressed, the teachers were introduced to each separate component of a circuit in asimilar way. After the battery was the resistor, then the LED, then the switch and finally thebreadboard. As each component was introduced the teachers were given a loosely structuredactivity that allowed them to explore the
Calculus, which most certainly covers this topic, but the problem“feels” different to students in the later course because the notation and setting have changed andthe purpose is specific to statistics rather than the more abstract concepts of the area of a two-dimensional region and anti-derivatives.Previous WorkIn recent years the authors have been exploring ways to reframe course assignments to provide agreater variety of application and visualization avenues to enhance critical thinking and promptstudent reflection. The objective is to provide multiple levels of connections that promotestudents’ cognitive retention.

that the national education system does not focus on thedevelopment of STEM competencies. As a result, the motivation of engineering students inmathematics courses is continuously hampered because of deficiencies in prerequisites.The case study presented in this paper is part of a wider project conducted at our institution.The project involved several math courses taken by first and second year engineeringstudents. The main objective of this project was to support mathematics instructors in theprocess of contributing to improve student learning, by continuously reflecting on theeffectiveness of the pedagogical practices that are applied inside and outside the classroom,while adopting a continuous improvement culture that benefits student
engineering calculus course taught via synchronous broadcast at a mid-size,Western, public university. The instructional innovation required first year calculus students toparticipate in an asynchronous, online discussion forum for graded credit. Data, consisting ofwritten reflections and transcribed interviews, were gathered from three STEM faculty memberswho each played a different role in the change process: a mathematics instructor implementingthe online forum within his course; an engineering faculty peer-mentor assisting with theimplementation of the online forum; and a STEM education faculty member evaluating theimplementation and observing the process of change. Situated within the interpretive researchparadigm, this study uses exploratory

The idea is toengage students in a context-rich problem, through the use of a driving question, to guide themthrough active learning modules exploring core concepts, and to lead them to a solutionmethodology. The production of a final report serves as a mechanism that allows them to revisetheir original solution based on a synthesis of the knowledge and understanding gained throughthe learning modules.The developmental framework for instructors using EFFECTs begins with the identification ofthe concepts to be studied; in general these are difficult concepts. Next, these concepts areassociated with active learning activities; each concept could be associated with a single

. APOS theory is initiated with Piaget’stheory of reflective abstraction [17] and got expanded to K16 mathematics education and RUME in recent years. Itwas applied in 1997 to mathematical topics for analyzing combined math knowledge of a student in a specificsubject [1]. Action, process, object, and schema are the mental structures proposed as a part of the APOS theory tofollow developmental stages of the learners. The main goal of this theory is to observe and categorize mentalstructures through observations of learners’ mental mechanisms; it is important to understand the totality ofknowledge and its’ reflection in applications.In the relevant APOS literature, learners’ conceptual view of the function was studied in [3] by relying on

Topics covered include: Constructivism, Motivation, Problem solving,Engaging with Groups, Grading and Feedback, and Metacognition (see Appendix A for fullcourse syllabus)These topics are organized around three main modules during the semester. The first one is basedon understanding the learning process as an elaborated process where
of the reflection when theengineering students and the beginning teachers reflected on the engineering design process theyimplemented during the activity. They compared this to the mathematical practice standards theyare expected to implement throughout their classrooms. What occurred during this discussionwere many connections among the different aspects of these two descriptions. They sawconnections between the mathematical expectations to make sense of the problem and theengineering process of identifying the needs and constraints. They linked the mathematicalstandards of reasoning abstractly and constructing viable arguments to the engineering processesof developing possible solutions and selecting promising solutions.

Rather than conduct a quasi-experimental design with a selection of GTAs participating incase analysis and others not, we instead used mixed qualitative and quantitative methods tocollect and analyze data solely from participants who experienced the use of case analysis in theirfirst semester of graduate school. This paper focuses in particular on two quantitative measures(survey data and student performance) and on two qualitative measures (case discussion recordsand reflective writings). We give a summary of the data within each of those four categoriesseparately. However, the nature of the research questions is such that a more significant analysisinvolves integration of those

Application of the instrument lead us to reflect that, once the appropriation is achievedthrough the motion context, it could be easier for students to apply it without connection with areal context. It also reveals the difficulties for interpreting graphical information based on thederivative function. These findings are part of the overall results of a doctoral dissertationconcerning with the use of digital technologies for the learning of Calculus.Keywords: Calculus learning, digital technologies, linear motion, real context, mediation.BackgroundDigital technologies are important tools in our daily activities, and it looks easy to use them inclassroom to support learning.

The professional development model consisted of two full days of inquiry experience anda half-day at the end of implementation dedicated to reflection of practice. The first day ofprofessional development focused mainly on Algebra concepts and was given prior toimplementing any of the Math Out of the Box lessons. After teachers implemented the tenlessons relating to Algebra, they returned for the second day of professional development dealingprimarily with data concepts. Teachers were also given the opportunity to reflect on the Algebralessons and discuss issues relating to implementation with their peers. Topics such as

In our work we targeted the theme of AcademicChallenge, which includes four engagement indicators: Higher-Order Learning, Reflective andIntegrative Learning, Learning Strategies, and Quantitative Reasoning. We attempted to improvein our students taking calculus courses the Higher-Order Learning component: Applying facts,theories, or methods to practical problems or new situations, the Reflective and IntegratingLearning component: Combining ideas from different courses when completing assignments,and the Quantitative Reasoning component: Reaching conclusions based on own analysis ofnumerical information.Following the revised Boom’s taxonomy of educational objectives, we targeted levels three –Applying, and four

The authors then used acommon rubric focused on desired student learning outcomes to evaluate changes between theinitial and final concept maps and created radar plots to display the results. Both authors werestruck by differences in what we had expected to see and what students actually reported, as wellas by how strongly students reflected some of what we tried

Through integrating them with the ideas given by the architects we developed the concepts of learning activities in the course.Data on learning outcomes and students’ reflections were collected by:• Design project portfolios The design assessment criteria were based on the existing practice of studio evaluation and referred to the three following aspects: concept, planning/detailing, and representation/expression. The mathematics assessment criteria were: perception of mathematical problems, solving applied problems, precision in drawing geometrical objects, accuracy of calculations and parametric solutions.

These objects can bedragged around the screen, which allows the users to observe the consequences of their draggingto understand the relations among the different objects. Users act on geometric objects and DGEsreact to their actions in a manner that corresponds to engineered infrastructure that responds tothe theory of geometry [8, 9]. This co-active relationship between the environment and usersallows users to monitor and reflect on their activity. In an instrument-mediated activity in DGE,the environment

From these data a movie wascreated as described above. In the following figures (Figures 10 to 14) snapshots are shown,which were taken at different evolutionary phases of wave phenomena that occurred in thecourse of the numerical simulation.The snapshot in Figure 10 shows two wave fronts that have already established and propagatetowards each other. Both regions confined by the wave fronts show already a rich internalstructure that is caused by several reflections at the boundaries (Dirichlet boundary conditionsproduce fixed end wave reflections) and by interference.Figure 10: Array of 261206
