In the February 1977 issue of the Mathematics Teacher, Fred Blaisdell and Art Indelicato coauthored an article entitled “Finding Chord Factors of Geodesic Domes.” Their approach involved threedimensional coordinate geometry and vector analysis, and the opinion was expressed that “the mathematics of geodesic domes is well within the capability of most senior high school mathematics analysis classes.”

The success of Mathematics Teacher is very much dependent on the volunteer efforts of many mathematics educators. Those who serve as department editors, manuscript referees, and publications and courseware reviewers include high school mathematics teachers, curriculum designers, college and university mathematicians, and teacher educators. Their contributions are deeply appreciated.

The program which is now being planned for this summer meeting of N.C.T.M. in Los Angeles will include general sessions addressed by nationally known speakers, a banquet, a luncheon, and many sectional meetings. These meetings should be of interest to teachers of elementary arithmetic, and junior and senior high school mathematics, as well as to teachers of junior and senior college mathematics. Special sections will also deal with aspects of teacher education in mathematics.

In arithmetic through the eighth grade and in first year algebra, is not the thorough understanding of fundamental principles of first importance? That this need of first importance has not been generally taken care of, is evidenced in many ways: (1) Such reports as that given by Admiral Nimitz, pointing out the weakness of our boys in junior and senior high school mathematics. (2) J. Kadushin's statements about the inability of men in the factories to handle simplest work in fractions, and their fear of taking any course in mathematics. (3) Constant complaint from teachers of physics, chemistry and algebra theory as to ignorance of the formula: what it is, what can and cannot be done to it. (4) The experience of much tutoring going on in universities, showing that great numbers have trouble with college mathematics because they did never really understand their work in arithmetic and algebra.

I do not think that the various departments, so called, in The Mathematics Teacher are equally interesting or equally valuable, but a new department, introduced in the January, 1955, issue, is one that I think should receive the support of all teachers of mathematics whether or not they are actually members of The National Council of Teachers of Mathematics. I refer, of course, to the new department edited by Kinney and Dawson of Stanford University. It will have my full support because I think that we have made a failure, more or less, of the junior high school movement.

The study investigated senior high school mathematics teachers’ perception and practices of classroom assessment since assessment is considered a critical tool for assessing the achievement of learning objectives in particular and educational goals in general. The study adopted a mixed-methods design. Sixty-two mathematics teachers were sampled from the selected schools to participate in the study. The instrument used in the data collection was a questionnaire. The internal consistency of the instrument designed had a calculated Cronbach alpha reliability coefficient of 0.74. The quantitative data gathered were analysed using descriptive statistics. The results from the study revealed that mathematics teachers had a positive perception about classroom assessment as most of them indicated that assessment is a tool to inform teaching and learning. There were, however, few teachers who still had a negative perception about assessment. Their reasons being that assessment had always been a tool for assigning grades and also used to promote students, hence had little benefit to teaching and learning process. The study also showed that the mathematics teachers’ practices of classroom assessment did not match up to the views they held about classroom assessment. Retraining of teachers through seminars and workshops were therefore recommended.
