The aim of the 2018 International Association for Development of the Information Society (IADIS) Cognition and Exploratory Learning in the Digital Age (CELDA) conference was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There have been advances in both cognitive…

Discusses approach to integrating computer programing into a calculus-based physics survey college course which stresses three major uses of computers: data reduction, calculation, and simulation. An initial programing exercise and practical constraints--time a student can allot to course and student's level of confidence--are mentioned. (EJS)

Discusses how computational errors arise in analysis of data and how they can be minimized. Shows that all computations are subject to roundoff/truncation errors and how such errors are propagated and influence the stability and condition of a reaction. Applications to procedures used in analytical chemistry are addressed. (JN)

When problems defy solution, mathematicians can settle for "almost." This branch of mathematics (called computational complexity) encompasses both the number of parts involved in a problem and the intricacy of their interrelatedness. Current research in this area is discussed, considering various computer applications involved. (JN)

Many institutional researchers will find that the microcomputer leads to greater efficiency in everything that they do, especially in the two most critical elements of their jobs: thinking and communicating. (Author/MLW)

A method is given for computer calculation of transcendental functions. (MK)

The rule of 78 is used by banks and loan companies to compute the amounts due when installment loans are paid early. Describes an unexpected case of negative amortization when the rule is applied. Presents an actual problem and discusses the case. (YP)

To answer students' questions about predicting grade averages or projecting grades needed to attain specific grade goals, academic advisors can use computerized grade calculations. Spreadsheet and HyperCard versions of grade calculation software are discussed and illustrated, and suggestions are offered for using them in specific advising…

Described are the use of spreadsheet programs in chemical engineering calculations using Lotus 1-2-3 macros. Discusses the macro commands, subroutine operations, and solution of partial differential equation. Provides examples of the subroutine programs and spreadsheet solution. (YP)

This paper proposes a model for a general interface between people and Computer Algebra Systems (CAS). The main features in the CAS interface are data navigation and the possibility of accessing powerful remote machines. This model is based on the idea of session management, in which the main engine of the tool enables interactions with the…

Increased student involvement with the computer at Delta State University, Mississippi, is considered. The university purchased a new computer, NCR Criterion, with six terminals and time-sharing BASIC. Two of these terminals are located in the Department of Physical Sciences, with the others located in the School of Business and in the University…
