The purpose of this study was to identify disciplinary core ideas that should be included in secondary school agriscience programs using a panel of experts in agricultural education, and to create a matrix of disciplinary core ideas, Agriculture, Food and Natural Resources career pathways performance indicators, and the Next Generation Science…

If the purpose of secondary schooling is to educate the upcoming generation to become active participants in society, evaluation of teaching and learning in the information-rich digital age should be underpinned by relevant theories and models. This article describes an evaluation tool developed using emerging ideas about knowledge creation and…

The monitoring and support of university freshmen is considered very important at many educational institutions. In this paper we describe the results of the educational data mining case study aimed at predicting the Electrical Engineering (EE) students drop out after the first semester of their studies or even before they enter the study program…

In a September 1988 "NASSP Bulletin" article, the author challenged readers to construct a question analysis matrix for curriculum evaluation in relation to critical thinking and problem solving. The author's solution, featuring various "domains" or components categorized according to planning, implementation, and outcome stages, comprises this…

Presents a mathematics problem on probability and matrices placed in a context with insects. Provides an overview, prerequisites, materials needed, and worksheets. (ASK)

Examines the similarities and fundamental differences between procedural programing and logic programing by comparing LogoWriter and PROLOG. Suggests that PROLOG may be a good first programing language for students to learn. (MVL)

Discusses the career matrix, a spreadsheet that identifies all the functions in an organization (horizontally) and the different levels of responsibility (vertically). Describes how technology teachers can develop their own matrix and use it for career awareness and planning with secondary students.(JOW)

Two statements concerning magic squares, considered as 3x3 matrices, are discussed and their proofs given using only high school level techniques. (MP)

The use of matrix sampling to overcome the impracticality of the pair comparison method for obtaining scale values is empirically tested. Results indicate that matrix sampling is useful in such applications. (Author/JKS)

Discussion of the use of computers in math instruction highlights two possibilities suggested in response to an earlier journal column: (1) a program written in BASIC for producing spirolaterals, and (2) the use of LOGO list processing to solve matrix problems for exploring geometric transformations. (LRW)

Presents an activity that illustrates how data stored in a matrix or list can be plotted as a graph in the parameter plotting mode on graphic calculators. (ASK)

Presents a lesson to teach matrices that emphasizes conceptual understanding and allows students to extend their investigations into important and relevant situations by using graphing calculators after important conceptual understanding has been developed. (KHR)

Described is a computer program that uses an interesting matrix method to generate Pythagorean triples. Program listings and output for two programs are included. (MNS)

Several approaches to the teaching of matrices are discussed. (SD)
