The results of an experiment in teaching engineering graphics using the traditional lecture-homework-laboratory technique are compared to a newer lecture homework proposal. Although the newer method reduces professor-student contact, it may prove to be as effective as the older method requiring laboratory instruction. (KR)

Presented is a proposed formula for determining the bearing angle and the slope angle for the line of intersection using the strike and dip angles of two given plane segments. Included is the development of the formula and three example problems. (KR)

Two graphics interface packages, PHIGS and HOOPS, are examined. A comparison of the two packages is made in light of the Iowa State University College of Engineering's need for educational software. Conclusions based on programing experience using both PHIGS and HOOPS are presented. (KR)

This report describes how to improve the effectiveness of the federal role in international Science and Engineering (S&E) based on relevant policy documents and reports and a wide range of different perspectives. The contents of the book are divided into four chapters. Chapter 1, "Introduction," includes "Process for Developing…

Investigated problem- and solution-related activity of (n=28) fourth and fifth graders in ill-defined and open-ended settings. In the course of their negotiations, students demonstrated an uncanny competence to frame and reframe problems and solutions and to decide courses of actions of different complexities in spite of the ambiguous nature of…

Explains the principles of assessment, lists goals and criteria for problem solving, and provides forms of evidence to evaluate students' understanding of the subject knowledge and ability of problem solving. (Contains 43 references.) (Author/YDS)

Carries on from an article about the context for assessment of problem solving skills. Describes other forms of evidence in problem solving skill besides the options given in the previous article. Lists eight forms of evidence related more directly to the problem solving process. Analyzes the relationship among some of these suggested forms of…

Describes differences in modes of thinking between natural sciences and engineering practitioners and presents a study investigating the differences in how engineering and chemistry faculty approach problem solving. (YDS)

The 11th International Conference on Educational Data Mining (EDM 2018) is held under the auspices of the International Educational Data Mining Society at the Templeton Landing in Buffalo, New York. This year's EDM conference was highly competitive, with 145 long and short paper submissions. Of these, 23 were accepted as full papers and 37…

Software-engineering education programs are intended to prepare students for a field that involves rapidly changing conditions and expectations. Thus, there is always a danger that the skills and the knowledge provided may soon become obsolete. This paper describes results and draws on experiences from the implementation of a computer…

The main advantage of using these concepts lies in the reduction of algebraic work involved in solving certain dynamics problems. A brief analytical treatment of the acceleration center and a description of a virtual work principle for equipollent systems in the kinetics of rigid bodies are provided. (MVL)

Past research has suggested that students need to be motivated by themselves (intrinsic learning motivation) and use higher-order cognitive skills so as to excel in problem solving, decision-making, and analytical reasoning in real-life situations. In this study, we examined the role of intrinsic learning motivation (ILM) and cumulative GPA in…

This document looks at specific applications of calculus to engineering. It is noted that for an automobile traveling at constant speed, the mathematical relationship between the directional heading and the angular deflection of the steering wheel can be calculated with respect to time. An analysis is presented which derives the relationship from…

A software package which can aid descriptive geometry instruction is described. Included are the features of the software and the software configuration. This software has been honored as the best and most advanced software of its kind in the People's Republic of China. (KR)

Students' reactions and performances were examined when taught engineering geometry concepts using a standard microcomputer-aided drafting software package. Two sample groups were compared based on their computer experience. Included are the methodology, data analysis, and conclusions. (KR)
