Information technologies and the development of professional knowledge and identity in teacher education

This paper addresses the preparation in ICT of preservice mathematics teachers. We describe the aims, assumptions, and work carried out in a course offered at the University of Lisbon and briefly discuss the processes involved in the development of professional knowledge and the formation of professional identities. Using a qualitative methodology, based on the administration of free-response questionnaires to the student teachers enrolled in the course in 1999-2000, we analyze their general perspectives about ICT, the implications of the use of ICT in their view of teaching methodologies, and their development of a professional identity. This work provides suggestions for teacher education practice and for further research

Information literacy in secondary education in the Netherlands: The new curriculum

The Dutch government decided to introduce in 1991 some form of comprehensive lower secondary education for grades 7–9. The Minister of Education and Sciences appointed committees for all fourteen subject areas to prepare attainment targets for these domains. The Committee for Information Literacy and Computer Literacy (ICL) was given the task not only to prepare objectives for a 20-h course on ICL, but also to advise the committees for the other subject areas on how to incorporate information technology into their recommendations. The ICL Committee concluded that a course of 20 h was too little for the subject area of information literacy and computer literacy, and decided to generate objectives for the whole domain of ICL, and to prepare proposals for the strategies by which information literacy and computer literacy can be integrated into the new lower secondary school curriculum

Are Early Investments In Computer Skills Rewarded In The Labor Market?

The paper assesses the relationship between investments in computer skills by adolescents and earnings at age 26. The heaviest investors earned 9 to 16 percent more than otherwise equivalent NELS-88 classmates. The payoff to early computer skills was substantial in jobs involving intense and complex uses of computers; negligible when computers were not used at work. It was non-gaming use of computers outside of school that enhanced future earnings, not playing video/computer games—which lowered earnings. Children in low SES families invested less in computer skills and thus benefited less from the job opportunities generated by the digital revolution

Early Determinants of Women in the IT Workforce: A Model of Girls’ Career Choices

Purpose – To develop a testable model for girls’ career choices in technology fields based on past research and hypotheses about the future of the information technology (IT) workforce. Design/Methodology/Approach – Review and assimilation of literature from education, psychology, sociology, computer science, IT, and business in a model that identifies factors that can potentially influence a girl’s choice towards or against IT careers. The factors are categorized into social factors (family, peers, and media), structural factors (computer use, teacher/counselor influence, same sex versus coeducational schools), and individual differences. The impact of culture on these various factors is also explored. Findings – The model indicates that parents, particularly fathers, are the key influencers of girls’ choice of IT careers. Teachers and counselors provide little or no career direction. Hypotheses propose that early access to computers may reduce intimidation with technology and that same-sex education may serve to reduce career bias against IT. Research Limitations/Implications – While the model is multidisciplinary, much of research from which it draws is five to eight years old. Patterns of career choices, availability of technology, increased independence of women and girls, offshore/nearshore outsourcings of IT jobs are just some of the factors that may be insufficiently addressed in this study. Practical Implications – A “Recommendations” section provides some practical steps to increase the involvement of girls in IT-related careers and activities at an early age. The article identifies cultural research as a limitation and ways to address this. Originality/value – The paper is an assimilation of literature from diverse fields and provides a testable model for research on gender and IT

Signaling the Competencies of High School Students to Employers

[Excerpt] The fundamental cause of the low effort level of American students, parents, and voters in school elections is the absence of good signals of effort and accomplishment and the consequent lack of rewards for learning. In most other advanced countries mastery of the curriculum is assessed by examinations that are set and graded at the national or regional level. Grades on these exams signal the student\u27s achievement to employers and colleges and influence the jobs that graduates get and the universities and programs to which they are admitted. Exam results also influence school reputations and in some countries the number of students applying for admission to the school. In the United States, by contrast, students take aptitude tests that are not intended to assess the learning that has occurred in most of the classes taken in high school. The primary signals of academic achievement are diplomas awarded for time spent in school and grades and rank in class—criteria that assess achievement relative to other students in the school or classroom, not relative to an external standard

Development of pre-service mathematics teachers’ professional knowledge and identity in working with information and communication technology

This paper describes the work undertaken in a course in communication and information technology in a pre-service program for secondary school mathematics teachers. This course aimed to help pre-service teachers develop a positive attitude regarding ICT and use it confidently. It focused on the exploration of educational software and of the Internet’s potential as a means of research and production of web sites. We discuss how the pre-service mathematics teachers evaluate their work concerning their commitment, difficulties they found, learning they identified, and personal relationship. We also analyse the effects of the course on the development of their professional knowledge and identity

Three Puzzles on Mathematics, Computation, and Games

In this lecture I will talk about three mathematical puzzles involving mathematics and computation that have preoccupied me over the years. The first puzzle is to understand the amazing success of the simplex algorithm for linear programming. The second puzzle is about errors made when votes are counted during elections. The third puzzle is: are quantum computers possible?Comment: ICM 2018 plenary lecture, Rio de Janeiro, 36 pages, 7 Figure
