Image-text conversion for web-based drawing involves mental activities of reification which sometimes leads students fluent in graphical hand skills to find it difficult to learn program code drawing. 35 people completed experiments on Topics 1 and 2 and 30 people completed experiments on Topics 1 to 3 on webpage design. A pretest and posttest…

An assessment of graphic literacy was developed by articulating and subsequently validating a skills-based cognitive model intended to substantiate the plausibility of score interpretations. Model validation involved use of multiple sources of evidence derived from large-scale field testing and cognitive labs studies. Data from large-scale field…

The ability to switch between various representations is an invaluable problem-solving skill in physics. In addition, research has shown that using multiple representations can greatly enhance a person's understanding of mathematical and physical concepts. This paper describes a study of student difficulties regarding interpreting, constructing,…

In this work, we analyze the results obtained by a group of freshmen students in a test of prior knowledge on technical drawing carried out before and after attending an introductory course on this subject. The aim of this course was to help students to gain knowledge necessary to take full advantage of the CAD software that is regularly used to…

This article reports on a research effort that investigated whether the use of Microcomputer-Based Labs (MBLs), implemented within an inquiry-based activity sequence on phase transformations (melting and freezing), contributes to the development of fourth grade (9-10 year-old) students' conceptual understanding and ability to construct and…

Describes the design of the Computer-Supported Intentional Learning Environment (CSILE), a database that allows the storage and retrieval of information in several media, e.g., text and drawings. Research on cognitive abilities and learning strategies is reviewed, learner control is discussed, and the implementation of CSILE in grades five and six…

This study compared interaction with a computer vs. observation as learning situations for low and high ability student's learning of spatial visualization and geometric transformations. Thirty-two fifth grade boys took the Differential Aptitude Test, Space Relations Subset (DAT), and then participated in the experiment. Pre-test and post-test…
