Statistics and the recency and place of statistics

The scope of statistics and the recency and place of statistics  in the school curriculum must be considered when discussing the beliefs of teachers involved in statistics education. These beliefs may be very different according to the age and stage of their students. Teachers also have a variety of prior life and academic experience. Some may have formally studied Statistics problems at school and some may not; some may have taken a course in Statistics help as part of their academic teacher training and others may not. For those who have formally studied statistics, their views as a teacher may be closely aligned to their views as a student, especially if they have not been teaching for very long. If, on the other hand, some Statistics tutor/teachers’ encounters with Statistics questions and Statistics answers have been within other disciplines or in everyday life situations then this experience may inform their belief framework. Finally, even if they have completed a statistics course in their pre-service training, the resulting beliefs may vary because of the relative emphases on theoretical statistics, applied statistics, and statistics education issues within the course.  Nowadays  free Statistics help is easily to find on the internet.

With this background in mind, there are a number of domains in which beliefs seem to be significant for teachers and the teaching of statistics in schools. In 1997, Gal et al. proposed some key areas for investigation, such as what teachers believe about statistics itself, the relationship between mathematics and statistics, the place of statistics in the curriculum, what statistics is important for students to learn, and how students learn statistics. The sections that follow examine these questions and some results and speculations will be presented. Shaughnessy (2007, p. 1001), however, points out that despite the years since Gal and colleagues proposed their questions, and despite a reiterated call for work in the area by Batanero, Garfield, Ottaviani, and Truran (2000), very little work has been done. The surveys by McLeod (1992), on students’ beliefs in mathematics more generally, and by Thompson (1992) and Philipp (2007) on teachers’ beliefs, give insights into possible issues, but statistics education is absent from their considerations. There were only a handful of papers on the topic presented at the ICMI/IASE conference in 2008, and what little has been done involves  case studies and/or small or convenience samples. Consequently, results about both teachers’ beliefs in mathematics education and tertiary students’ beliefs in statistics education may provide grounds for speculation about teachers and statistics education. Another section will consider influences on and impacts of beliefs, and belief change.

Research/Resource Sharing

Given the changing direction and magnitude of support for research sponsored by the federal government and industry, coupled with the increased competition from federal laboratories and international groups, engineering colleges must look for new opportunities to establish collaborative research alliances. Some alliances may be local or regional; others will be “virtual,” that is, national or international alliances established through the emerging global information superhighway.

Regional consortia of engineering colleges, for example, may share research facilities, teaching laboratories and faculty. Faculty tenure might even reside with a consortium and not with the individual institutions. Other types of consortia could combine the resources of universities and industry, universities and federal facilities – such as national laboratories – or a combination of all three. The aim is not to create new bureaucracies and expense, but to facilitate high-quality research and teaching that is both effective and efficient.

The National Science Foundation has taken the lead in funding experiments in research and education resource-sharing, and in creation of virtual research and education teams. Such experiments also should be encouraged through the Engineering Research Center (ERC) and Science and Technology Center (STC) programs. Lessons learned by the NSF Engineering Education Coalitions in creating “virtual” research and education teams should be applied to these experiments.

To ensure high-quality research and education, federal funding for science and technology must be distributed through open competition, based on peer review. To enhance technology transfer and industry-university research partnerships, universities, corporations and federal agencies should ensure they have flexible and negotiable policies governing intellectual property rights.

Federal agencies that fund research and education should explore ways of encouraging educational institutions, research organizations, federal laboratories, and industry to share resources. They should provide special consideration for funding projects that are developed by consortia of institutions.

Federal funding for science and technology should be allocated in open competition, based on peer review.

To enhance technology transfer and industry-university research partnerships, universities, industries, and federal agencies should develop flexible and negotiable policies governing intellectual property rights.

Engineering education today is adapting to the changing context of engineering practice, but more can be done to speed and improve the process. A crucial means of accomplishing needed change is through partnerships with industry, government, and the broader educational communities. The policy statements and action items developed in this project are intended to help ensure that engineering education will be RELEVANT, ATTRACTIVE and CONNECTED well into the next century.

Reshaping the Curriculum

Through its accreditation process, the U.S. engineering education system has continually reexamined and re-energized the engineering curricula. Engineering fundamentals have been and will continue to be the core of the engineering curriculum. But because engineers now operate in a world where their accomplishments are often more limited by societal considerations than by technical capabilities, they are engaging in a wider range of activities throughout their professional lives. Thus, engineering education must take into account the social, economic, and political contexts of engineering practice; help students develop teamwork and communication skills; and motivate them to acquire new knowledge and capabilities on their own. Because many modern engineering projects require a combination of several disciplines, students also need exposure to the integrative field of systems engineering.

In essence, an engineering education today aims to prepare an engineer to be successful in the changing workplace. It aims to equip students with technical knowledge and capabilities, flexibility and an understanding of the societal context of engineering.

Engineering schools should not seek to develop these contextual and process skills through separate courses, but by incorporating them into existing curricula and through non-classroom activities. Coursework should feature multidisciplinary, collaborative, active learning; and take into account students’ varied learning styles.

One factor that will promote development of students’ “process” skills is widespread use of multimedia, worldwide information networks. Using this resource, students can access new information and coursework, as well as interact with other students, researchers, practicing engineers in industry and government, and experts from around the world. These changes in the teaching and learning environment will make engineering education more attractive to both students and faculty, if faculty are given the opportunity to stay up-to-date.

Finally, all engineering colleges must address the issue of ethics. While ethics is a complex and difficult topic, engineering administrators and faculty must help students understand that throughout their careers they will encounter ethical issues which they will need to recognize and deal with rationally. Whether engineers are conducting engineering research, managing a company, or building bridges and office buildings, their decisions affect the lives and property of the greater community. Students must understand the importance of upholding that public trust.

While recognizing and encouraging diverse institutional missions and changing industry needs, colleges of engineering must re-examine their curricula and programs to ensure they prepare their students for the broadened world of engineering work. This process has begun among most engineering colleges and must be accelerated with the aim to incorporate:

  • team skills, including collaborative, active learning;
  • communication skills;
  • leadership;
  • a systems perspective;
  • an understanding and appreciation of the diversity of students, faculty, and staff;
  • an appreciation of different cultures and business practices, and the understanding that the practice of engineering is now global;
  • integration of knowledge throughout the curriculum;
  • a multi-disciplinary perspective;
  • a commitment to quality, timeliness and continuous improvement;
  • undergraduate research and engineering work experience;
  • understanding of the societal, economic and environmental impacts of engineering decisions;
  • and ethics.

Re-Examining Faculty Rewards

In whatever way an engineering college defines its mission, to be successful, it must ensure that its faculty reward system supports its goals. Faculty members often face the difficult task of trying to balance the several activities they need for professional advancement, such as research and undergraduate teaching, with a host of new activities their colleagues, students and the public expect them to accomplish. These can include curricula development, interdisciplinary collaboration, work with industry, development of continuing education programs, community outreach, and mentoring of other faculty members and students. As engineering colleges develop institutional missions, they have an opportunity to recraft their faculty reward system to better synchronize faculty rewards with their new, or re-affirmed, institutional expectations.

Changing the faculty reward system will not be an easy task. Faculty rewards are heavily driven by incentives created across the entire university and are part of a nationwide network. Nevertheless, it is important that rewards reflect the goals of the institution and it is important to begin the conversation now. As each institution establishes its vision and charts new directions, it should ensure that its faculty reward system supports the institutional goals.

Engineering Schools and Engineering Careers

We live in a time of revolutionary change. Not only is the world relying increasingly on technology for economic growth and job development, but the nation is making the difficult transition of refocusing a significant amount of its technology investment from national security to international economic competitiveness. At the same time, we view technology as important in helping solve many difficult societal problems, from creating environmentally-sustainable development and improving communications, to devising more effective and cost-efficient health care systems. Communications developments alone are leading to profound redefinitions of such concepts as “community,” “library,” “corporation,” and even “university.”

Within this technological context, engineers play an ever more significant role. They develop new manufacturing processes and products; create and manage energy, transportation and communications systems; prevent new and redress old environmental problems; create pioneering health care devices; and, in general, make technology work. Through these activities, engineers create a huge potential for the private sector to develop national wealth. As noted by Richard Morrow, past chairman of the National Academy of Engineering, “the nation with the best engineering talent is in possession of the core ingredient of comparative economic and industrial advantage.”

And just as important as their specific technical skills, engineers receive valuable preparation for a host of other careers in such areas as finance, medicine, law and management. These professions require analytical, integrative and problem-solving abilities, all of which are part of an engineering education. Thus, engineering is an ideal undergraduate education for living and working in the technologically-dependent society of the twenty-first century.

Responding to Changing Needs

One of the strengths of engineering education in the United States is the broad spectrum of engineering colleges whose development has been unconstrained by a single, centrally-prescribed mission. The more than 300 colleges of engineering range from highly research-intensive institutions to those that focus largely on undergraduate education, with many variations in between. Even with the considerable differences in missions, undergraduate engineering education programs maintain universal core curriculum content and minimum standards through the Accreditation Board for Engineering and Technology (ABET), a national partnership between academics and practicing engineers. Additionally, most engineering schools have forged close relationships with industry and benefit from annual assessments of their programs by external advisory boards that have strong industry participation.

While U.S. engineering education has served the nation well, there is broad recognition that it must change to meet new challenges. This is fully in keeping with its history of changing to be consistent with national needs. Today, engineering colleges must not only provide their graduates with intellectual development and superb technical capabilities, but following industry’s lead, those colleges must educate their students to work as part of teams, communicate well, and understand the economic, social, environmental and international context of their professional activities. These changes are vital to the nation’s industrial strength and to the ability of engineers to serve as technology and policy decision makers.

Most important, engineering education programs must attract an ethnic and social diversity of students that better reflects the diversity of the U.S. and takes full advantage of the nation’s talents. Not only does the engineering profession require a spectrum of skills and backgrounds, but it should preserve its historical role as a profession of upward mobility.

In response to these needs, engineering colleges throughout the country are experimenting with new approaches to curricula, rethinking traditional teaching modes, and developing innovative ways to recruit and retain students from underrepresented groups. The largest and potentially most revolutionary effort is led by the consortia of colleges funded by the National Science Foundation’s Engineering Education Coalitions program. These national engineering college consortia each include a variety of schools ranging from predominantly undergraduate institutions to the most research intensive. The consortia are working to redesign curricula and improve teaching methodologies, each offering a different perspective and strategy.

While it is too early to gauge the success of the coalitions, they exemplify the engineering education community’s leadership and willingness to adjust to change. We applaud and encourage these efforts, but also stress the importance of including partnerships with industry and government in reformulating engineering education.

Engineering Yesterday, Today, and Tomorrow

In early times, the practice of engineering was that of a trade or craft with training occurring through some form of apprenticeship. As it developed into a profession and more recently as an academic discipline, it took on the shape of other academic disciplines, with preparation being an education rather than a training. An important turning point in the Unites States was the land grant college act (Morrill act) of 1862 which established an institution for the teaching of agriculture and the mechanical arts (engineering) in each state. This officially legitimated engineering in higher education although it still had the form of training. Interestingly, this act came into being during the American Civil War and was signed by Abraham Lincoln.

World-War II was the second turning point when it was discovered that many of the technical innovations necessary for that effort came from scientists, mathematicians, and theoretically educated engineers rather than traditionally trained engineers. Most engineers prior to that time had been trained to develop and apply ideas already in existence, not to create new solutions to new problems. After WWII, the university curricula in engineering became much more scientific and mathematical. It took on more elements of an education rather than a training. It slowly became a real academic discipline in its own right rather than only an application of other disciplines. However, it retains the integrating role of applying the physical and life sciences using some of the tools of the social sciences, law, and policy and the values derived from the humanities, letters, arts, and business.

We are now going through a third transition in engineering in response to many factors in society and in technology itself. In the larger picture, society went through the agricultural phase, the industrial phase, and now the information phase. These three phases of civilization created and were created by the most powerful and applicable technologies of the time. Engineering is and will be the creative element in the information age as it has been in preceding ages.
