This book was published exclusively with the goal of preparing students to be future elementary school teachers. This four-color book is exactly the same as Wheeler and Wheeler's Modern Mathematics, Ninth Edition with the following additions: The preface was written directly with the goal of educating elementary school teachers, NCTM Standards are included in the book's end papers, and Reproductions of actual pages from four-color elementary school textbooks have been added.Guided by a team of reviewers and suggestions from more than 130 professors, the authors have produced an important revision. At the beginning of each section, goals and objectives have been replaced by statements from the NCTM Standards. Within each section the authors present the content, examples, problem sets, and laboratory exercises that fulfill the philosophy and the direction suggested by the Standards. In this edition, Ruric Wheeler is joined by his son, Ed, as co-author.An activities manual for prospective elementary school teachers has been completely rewritten by a team of authors with many years of experience teaching elementary and middle school students. In addition to a rich variety of activities it includes ''Talk to Teachers,'' a section that discusses the significance of each activity in the growth and preparation of the young student.
This comprehensive sourcebook, which identifies and locates kits, games, and manipulatives, is organized into broad subject areas, including reading and language arts, mathematics, social studies, science and health, and the arts. Some 1,500 entries provide physical descriptions of the materials and
Most organisations try to protect their systems from unauthorised access, usually through passwords. Considerable resources are spent designing secure authentication mechanisms, but the number of security breaches and problems is still increasing (DeAlvare, 1990; Gordon, 1995; Hitchings, 1995). Unauthorised access to systems, and resulting theft of information or misuse of the system, is usually due to hackers "cracking" user passwords, or obtaining them through social engineering. System security, unlike other fields of system development, has to date been regarded as an entirely technical issue - little research has been done on usability or human factors related to use of security mechanisms. Hitchings (1995) concludes that this narrow perspective has produced security mechanisms which are much less effective than they are generally thought to be. Davis & Price (1987) point out that, since security is designed, implemented, used and breached by people, human factors should be considered in the design of security mechanism. It seems that currently hackers pay more attention to human factors than security designers do. The technique of social engineering, for instanc- obtaining passwords by deception and persuasion- exploits users' lack of security awareness. Hitchings (1995) also suggests that organisational factors ought to be considered when assessing security systems. The aim of the study described in this paper was to identify usability and organisational factors which affect the use of passwords. The following section provides a brief overview of authentication systems along with usability and organisational issues which have been identified to date. 1.
This open access book, inspired by the ICME 13 topic study group “Affect, beliefs and identity in mathematics education”, presents the latest trends in research in the area. Following an introduction and a survey chapter providing a concise overview of the state-of-art in the field of mathematics-related affect, the book is divided into three main sections: motivation and values, engagement, and identity in mathematics education. Each section comprises several independent chapters based on original research, as well as a reflective commentary by an expert in the area. Collectively, the chapters present a rich methodological spectrum, from narrative analysis to structural equation modelling. In the final chapter, the editors look ahead to future directions in the area of mathematics-education-related affect. It is a timely resource for all those interested in the interaction between affect and mathematics education.
Pentominoes are colored geometric shapes that fit together like puzzle pieces. Activities with them encourage development of problem solving and visual perception skills, and recognition of geometric shapes and relationships. Set includes 6 sets of 12 pieces each.
