Sozen-Ozdogan, Sinem; Akyuz, Didem; Stephan, Michelle – Australian Mathematics Education Journal, 2019
The mathematics standards for many countries include teaching and learning ratios, typically with efficient algorithms and strategies (Australian Curriculum: Mathematics, Assessment and Reporting Authority, 2017; National Council of Teachers of Mathematics, 2014). In the 1990s, Cramer and Post (1993) claimed that school mathematics mostly involves…

Hassani, Mehdi; Kippen, Rebecca; Mills, Terence – Australian Senior Mathematics Journal, 2016
Life tables are mathematical tables that document probabilities of dying and life expectancies at different ages in a society. Thus, the life table contains some essential features of the health of a population. Probability is often regarded as a difficult branch of mathematics. Life tables provide an interesting approach to introducing concepts…

Prodromou, Theodosia – Statistics Education Research Journal, 2016
In the Australian mathematics curriculum, Year 12 students (aged 16-17) are asked to solve conditional probability problems that involve the representation of the problem situation with two-way tables or three-dimensional diagrams and consider sampling procedures that result in different correct answers. In a small exploratory study, we…

Fonger, Nicole L.; Davis, Jon D.; Rohwer, Mary Lou – School Science and Mathematics, 2018
This research addresses the issue of how to support students' representational fluency--the ability to create, move within, translate across, and derive meaning from external representations of mathematical ideas. The context of solving linear equations in a combined computer algebra system (CAS) and paper-and-pencil classroom environment is…

Whitney, Stephanie R. – Mathematics Teaching in the Middle School, 2014
Stephanie Whitney teaches in the department of teacher education at DePaul University in Chicago, Illinois. Her interest is in how students reason and make sense of mathematics, and how teachers can promote this behavior. Students should engage in reasoning and sense making daily in their mathematics classes. It is often through students'…

Fonger, Nicole L. – Mathematics Teacher, 2014
How can the key concept of equivalent expressions be addressed so that students strengthen their representational fluency with symbols, graphs, and numbers? How can research inform the synergistic use of both paper-and-pencil analysis and computer algebra systems (CAS) in a classroom learning environment? These and other related questions have…

Acevedo Nistal, A.; Van Dooren, W.; Verschaffel, L. – Educational Psychology, 2014
This study evaluates the effects of an intervention aimed at improving representational flexibility in linear-function problems. Forty-nine students aged 13-16 participated in the study. A pretest-intervention-posttest design with an experimental and control group was used. At pretest, both groups solved a choice test, where they could freely…

Cotton, Samuel E. – Technology Teacher, 2002
Many problem-solving activities include mathematical principles but students do not use them during the design and experimentation phases before creating a prototype or product. Restricting the amount and/or type of materials available to students will require them to calculate and requisition the materials needed. (JOW)

Garmire, Elsa – Technology Teacher, 2003
Describes an engineering design course that is taught at the postsecondary level but can be adapted for secondary education. It presents the steps in the design process and illustrates, using a matrix, the tradeoffs necessary in design. (JOW)

Garton, Bryan L.; Cano, Jamie – Journal of Agricultural Education, 1996
A study to describe the extent to which cooperating and student teachers (n=15) in agriculture used the problem- solving approach to teaching found that they spent less than 20% of their instructional time using it. Cooperating teachers use most of their time maintaining students' interest in the subject matter; student teachers spent time seeking…

Chaiklin, Seth – Cognitive Science: A Multidisciplinary Journal of Artificial Intelligence, Psychology and Language, 1984
This theoretical analysis articulates verbal rule properties and use implications, describes an empirical study examining characteristics of problem solving performance when verbal rules are instructed as a problem solving method, and discusses role of verbal rules in problem solving and implications for learning procedural skills.

Funkhouser, Charles; Dennis, J. Richard – Journal of Research on Computing in Education, 1992
Pretests measuring problem-solving ability were administered to 71 students in a high school mathematics class. One group was given computer-augmented instruction; the other group was given instruction augmented by mathematics laboratory activities. Posttest results for problem-solving ability were mixed, but the group receiving computer-augmented…

Greeno, James G.; Hall, Rogers P. – Phi Delta Kappan, 1997
Discusses the process of learning to construct and interpret representations from a social practice perspective. If students need to construct tables and graphs to complete a project report in mathematics or science, they can learn to consider whether these forms are effective at communicating important information. If students merely complete…

Mandinach, Ellen B. – Journal of Educational Computing Research, 1987
This study investigated the degree to which seventh- and eighth-grade students of different abilities acquired strategic planning knowledge from a problem-solving computer game called Wumpus. Regression analysis was used to determine the influences of individual differences and either activating or modeling instruction, and to assess transfer of…
