Chapter 11


Chapter 11
“Technology in Mathematics and Science Instruction”

1.     What Does TPACK Look Like in Science and Math Education?
A.     The union of the 3 knowledge domains (content, pedagogy, technology) to develop a lesson base from which a teacher can view a lesson and understand how technology can enhance the learning opportunities and experiences for students while also knowing the correct pedagogy to enhance the learning content
B.     For example, when teaching about magnetic north, instead of simply lecturing on the differences between geographic north and magnetic north, the teacher might have students use a magnetic field sensor and data collection software to monitor the magnetic field intensity as they identify magnetic north
2.     Issues and Problems in Mathematics Instructions
A.     Accountability for Standards in Mathematics
                                               i.     Principles and Standards for School Mathematics
à Released in 2000 by the National Council of Teachers of Mathematics
à Serves as the primary resource and guide for all who make decisions that affect the mathematics education of students in pre-K through grade 12
à Achievement of the vision of the document requires, “solid mathematics curriculum, competent and knowledgeable teachers who can integrate instruction with assessment, education policies that enhance and support learning, classrooms with ready access to technology, and a commitment to both equity and excellence.”
à Calls for a common foundation of mathematics to be learned by all students; the following six principles address the critical issues:
-      Equity
-      Curriculum
-      Teaching
-      Learning
-      Assessment
-      Technology (is essential in teaching and learning mathematics; it influences the mathematics that is taught and enhances students’ learning)
à Develops 5 content standards for pre-K through 12th grade
-      Numbers and operations
-      Algebra
-      Geometry
-      Measurement
-      Data analysis and probability
à Develops 5 process standards for pre-K through 12th grade
-      Problem solving
-      Reasoning and proof
-      Communication
-      Connections
-      Representations

5.     Issues and Problems in Science Instruction
A.     Accountability for Standards in Science
                                               i.     American Association for the Advancement of Science (AAAS)
à Science for All Americans (1989)
à Set out recommendations for what all students should know and be able to do in science, mathematics, and technology by the time they graduate from high school
à Challenges science teachers to ensure that all students are scientifically literate so that all children can participate in the everyday science discourse
                                              ii.     The National Research Council (NRC)
à National Science Education Standards (1995)
à Outlines the content that all students should know and be able to do
à Provides guidelines for assessing student learning in science
à Provides guidance for science teaching strategies, science teacher professional development, and the support necessary to deliver high-quality science education
à Describes the policies to bring coordination, consistency, and coherence to science education programs
                                            iii.     Many of the state standards documents have drawn their content from The Benchmarks for Science Literacy (AAAS, 1993) and/or The National Science Education Standards
                                            iv.     U.S. Department of Education and the National Science Foundation endorse mathematics and science curricula that “promote active learning, inquiry, problem solving, cooperative learning, and other instructional methods that motivate students.”
                                              v.     National Committee on Science Education Standards and Assessment (1992) state that “school science education must reflect science as it is practiced and that one goal of science education is to prepare students who understand the modes of reasoning of scientific  inquiry and can use them.”
                                            vi.     Inquiry-Oriented Instruction
à The basis for inquiry-oriented science instruction is developing opportunities for students to learn science process skills:
-      Collecting, sorting, and cataloging
-      Observing, note taking, and sketching
-      Interviewing, polling, and surveying
à  Research has shown that inquiry-based instruction is effective in developing the following:
-      Scientific literacy
-      Understanding of scientific process
-      Vocabulary knowledge
-      Conceptual understanding
-      Critical thinking
-      Positive attitudes towards science
-      Construction of logico-mathematical knowledge
à Research has identified 4 major ways technology is utilized in the successful inquiry-based science classroom:
-      As a productivity tool: technology aides in accomplishing tasks with greater efficiency, allowing students to spend more time on tasks that are more supportive of learning; for example, students spend less time on data management and calculations and more time interpreting and understanding the scientific concepts related to those data
-      Communicating ideas and information: students do not have to spend time constructing illustrations, graphs, and pictures, they can let the software format them, etc.
-      Investigating with technological tools: technology can aid in the fundamental practice of scientific investigation by collecting information and representing information appropriately; the most commonly used technological processes are simulation and data-gathering tools such as probes
-      Creating knowledge products: the use of technology can allow students to synthesize knowledge in more challenging ways through computer-generated graphs, pictures, hyper-links, etc.
                                           vii.     Integration of technology in the science classroom is dependent on an understanding of the definition of technology in the context of scientific teaching and learning
à Benchmarks for Science Literacy, AAAS, 1993:  “Technology once meant knowing how to do things—the practical arts or the study of the practical arts.  But it has also come to mean innovations such as pencils, television, aspirin, microscopes, etc., that people use for scientific purposes, and it refers to  human activities such as agriculture or manufacturing and even to processes such as animal breeding or voting or war that change certain aspects of the world.”
à National Science Education Standards, NRC, 1996: “The central distinguishing characteristic between science and technology is a difference in goal: the goal of science is to understand the natural world, and the goal of technology is to make modifications in the world to meet human needs.  Technology as a design is included in the Standards as parallel to science inquiry.”
B.     The Narrowing Pipeline of Scientific Talent
                                               i.     A trend has been identified in the declining number of students (especially females and minorities) pursuing studies in math, science, and engineering fields
                                              ii.     As a result of the declining numbers of students entering the STEM (science, technology, engineering, mathematics) fields, America is facing a growing crisis in a lack of leadership in these areas
                                            iii.     One of the first reports on the issue: Fueling the Pipeline: Attracting and Educating Math and Science Students (EMC Corp., 2003)
                                            iv.     http://media.umassp.edu/massedu/stem/science-and-engineering-pipeline.pdf
C.     Increasing Need for Scientific Literacy
                                               i.     The science benchmarks reflect a growing need for all citizens to be scientifically literate
                                              ii.     The economic and environmental welfare of the country depends on the character and quality of the science education that the nation’s schools are providing
D.    Difficulties in Teaching K – 8 Science, Study Conducted by Educational Testing Service
                                               i.     Research has compared the SAT scores of teacher candidates passing the Praxis II exam with the average scores for all college graduates
                                              ii.     Conclusions: the elementary education candidates have much lower math and verbal scores than other college graduates do
                                            iii.     The teaching of science for understanding has become difficult due to the lack of deep understanding on the part of the teacher
                                            iv.     The Eisenhower National Clearinghouse offers a guide to improving professional development in the areas of math, science, and technology; http://www.goenc.com/
E.     New Emphasis on and Controversies about Scientific Inquiry
                                               i.     Scientific inquiry: approaching problems scientifically
                                              ii.     When learning with technology focuses on inquiry-based learning, the following approaches are commonly adopted:
à Technology is viewed as a tool, much like a pencil  or pen, only more powerful
à Use of technology is primarily taught in the context of solving a problem
à Students help each other with the mechanics of the technology—in many classrooms, it is the students that are the experts
à Talking about and around the technology is as important as the technology itself; just as talk about how information can be applied is as important as the information itself
à Technology is used to augment the communication by expanding the audience and the expressive options
                                            iii.     The National Science Teachers Association recommends a combination of direct instruction and inquiry-based learning

à Calculator or computer based laboratory (CBL) are ideal for middle through high school students
                                            iii.     Visualizing data and phenomena
à Computer simulations differ from pictures in that students can manipulate computer simulations—they allow students to visualize macroscopic phenomena that are difficult to understand because they cannot be seen directly (i.e., phases of the moon)
à Visualization tools can also be used to see microscopic phenomena that are otherwise difficult/impossible to see (i.e., molecular structure or cellular growth)
à Another use of visualization tools is the ability to rotate images to view them from various vantage points
