### Computation in an algebra of test selection criteria [article]

Jan Pachl, Shmuel Zaks
1999 arXiv   pre-print
One of the key concepts in testing is that of adequate test sets. A test selection criterion decides which test sets are adequate.  ...  In this paper, a language schema for specifying a large class of test selection criteria is developed; the schema is based on two operations for building complex criteria from simple ones.  ...  The schema is based on two operations for combining selection criteria; with these two operations, test selection criteria form a well-behaved algebra.  ...

An important first step in attempting to reduce the incidence of such trauma would be to gain some insights regarding the correlates of success in eighth-grade algebra.  ...  In many schools, superior mathematics students are given the opportunity to study first-year algebra in the eighth grade as the first course of an accelerated mathematics program that culminates with Advanced  ...  DISCUSSION Of the variables included in the present study, an algebra prognosis test was identified as the best overall predictor of success in an eighth-grade algebra course.  ...

### Testing from Algebraic Specifications: Test Data Set Selection by Unfolding Axioms [chapter]

Marc Aiguier, Agnès Arnould, Clément Boin, Pascale Le Gall, Bruno Marre
2006 Lecture Notes in Computer Science
This paper deals with test data set selection from algebraic specifications. Test data set are generated from selection criteria which are usually defined to cover specification axioms.  ...  The unfolding selection criterion consists in covering the input domain of an operation using case analysis.  ...  In this paper, we are interested in the process of selecting test sets from algebraic specifications.  ...

Process algebras and specification languages are usually endowed with an operational semantics in the form of a transition system specification (TSS).  ...  An extension of the mentioned criteria to a setting with inequalities has been also proposed.  ...

### Application of PROLOG to test sets generation from algebraic specifications [chapter]

L. Bougé, N. Choquet, L. Fribourg, M. C. Gaudel
1985 Lecture Notes in Computer Science
We give formal definitions of the basic concepts required in our approach of functional testing. Then we discuss the problem of testing algebraic data types implementations.  ...  This allows the introduction of additional hypotheses and thus the description of an effective method for generating test sets. The method can be improved by using PROLOG.  ...  Gaudel thanks the members of IFIP-WG2.2 for fruitful discussions and comments. This research is supported by CIT-Alcatet.  ...

### iPads in the Mathematics Classroom: Developing Criteria for Selecting Appropriate Learning Apps

Taylor R. Harrison, Hollylynne S. Lee
2018 International Journal of Education in Mathematics Science and Technology
This research presents a set of sixteen criteria that can be used to evaluate the potential of an iPad app to be an effective mathematical learning tool.  ...  The evaluation instrument is presented, along with a discussion of each of the sixteen criteria. The instrument is then applied to seven apps designed for learning algebraic concepts.  ...  So, while there are many factors that can ultimately determine the benefit an iPad app will have on students' learning of mathematics, this instrument can assist designers in developing, and researchers  ...
