This open access book provides an overview of Felix Klein's ideas, highlighting developments in university teaching and school mathematics related to Klein's thoughts, stemming from the last century. It discusses the meaning, importance and the legacy of Klein's ideas today and in the future, within an international, global context. Presenting extended versions of the talks at the Thematic Afternoon at ICME-13, the book shows that many of Klein's ideas can be reinterpreted in the context of the current situation, and offers tips and advice for dealing with current problems in teacher education and teaching mathematics in secondary schools. It proves that old ideas are timeless, but that it takes competent, committed and assertive individuals to bring these ideas to life. Throughout his professional life, Felix Klein emphasised the importance of reflecting upon mathematics teaching and learning from both a mathematical and a psychological or educational point of view. He also strongly promoted the modernisation of mathematics in the classroom, and developed ideas on university lectures for student teachers, which he later consolidated at the beginning of the last century in the three books on elementary mathematics from a higher standpoint.

During the past decade, mathematics education has changed rapidly, giving rise to a polarization of opinions among the community of research mathematicians. What is the appropriate balance among theory, technique, and applications? What is the role of technology? How do we fulfill the needs of students entering other fields? The purpose of this volume, the proceedings of a conference held at the Mathematical Sciences Research Institute in Berkeley in 1996, is to present a serious discussion of these educational issues, with a balanced representation of opposing ideas. Part I deals with general issues in university mathematics education; Part II presents case studies on particular projects; Part III presents a range of opinions on mathematics education in elementary and secondary schools; and Part IV presents the reports of the working groups.

These selected addresses are based upon three affirmations. One is that the Living God has been revealed in Jesus Christ. Another is that there is an eternal life to be lived in the midst of time, in the presence of God, and by the power of His Spirit. The third is that this eternal life is entered into through an experience in which conscience, desire, and will are enlightened, renewed, and surrendered to Christ. Of that experience and its issues these addresses are the exposition. In the 1916 issue of "The Biblical World," a publication of the University of Chicago, a review of "The Evangel of the Strait Gate" evaluates the book. "The twenty-six sermons are full of the profound convictions that have inspired the best Christian preaching; but the expression is fresh and vigorous. There are few sermons of justification by faith which are clearer or more credible than Professor Clow's discourse on this theme under the fine title, "Dressed in Beauty Not My Own." The preacher presents his divisions, propositions, and titles of sections so plainly that there can be no least doubt as to how the subject was disposed in the preacher's mind. There fertile development of the texts in the volume, especially Ephesians 1:1, "The Threefold Environment." Also "A Song of the Upper Room," using the great hymn of Bernard of Clairvaux, is notably fresh and interesting. But the primary factor in the volume is the preacher's consciousness of the verity of the distinctly Christian experience."
