In the study reported here, I examined the diagrams that mathematically capable high school students produced in solving applied calculus problems in which a diagram was provided in the problem statement. Analyses of the diagrams contained in written solutions to selected free-response problems from the 1996 BC level Advanced Placement Calculus…

Computer technology can be integrated into science inquiry activities to increase student motivation and enhance and expand scientific thinking. Fifth-grade students used the visual thinking tools in the Kidspiration[R] software program to generate and represent a web of hypotheses around the question, "What affects the distance a marble rolls?"…

This article describes cross-cultural research on the relation between how people conceptualize nature and how they act in it. Mental models of nature differ dramatically among populations living in the same area and engaged in similar activities. This has novel implications for environmental decision making and management, including commons…

Passive students staring blankly at computer screens has been a worrisome image for many educators. Often they fear that technology can remove students from contact with the real world. Two technologies that have been in general use for many years, but are more recently appearing in the educational sector, provide the opportunity to reap the…

The continuous technological progress of the past few decades affords a different orientation to the teaching-learning process, which is useful and advantageous when mathematical concepts are transmitted. This article pursues two different aims. The first one is to examine the present state of the traditional process in relation to the concepts of…

In this study, we examined how students' levels of spatial visualization ability interact with learning physics in a microcomputer-based laboratory (MBL) environment. Undergraduate students who had taken an introductory physics course based on MBL tools were pre- and posttested at the beginning and at the end of the semester on spatial…

The author is an associate professor of animal studies at Colorado State University, but experienced learning difficulties in high school due to her place on the autism-Asperger's spectrum. She had uneven skills, and while algebra was impossible, she did well in courses in which she could use her visual-thinking and associative-thinking skills.…

White and group used a two question, open-ended tests to separately evaluate students' learning of specific biochemical concepts in the general biology lecture and laboratory, in the first performance assessment of molecular visualization in teaching biochemistry. Two studies were devoted to protein structure using globins followed by one…

This workbook for students in grades 3 through 5 is designed to help them understand how stress affects the body and to show them various positive ways of coping with stress in daily life. Fifteen lessons include definitions of stress, relaxation exercises, visualization techniques, problem-solving approaches, dealing with conflicts, the necessity…

This study was designed to investigate the effects of a dynamic instructional environment, English proficiency, and visualization level, independently and interactively, on middle school students' construction of the concepts of reflection and rotation. The effects of a dynamic instructional environment and English proficiency on students' two-…

Two instructional variables, visual illustrations and visual mental imagery, were compared for their influences on learning and cognitive strategies. It was hypothesized, based on dual-code theory, that attempts to combine the two would facilitate learning. In a completely randomized factorial design, treatments consisted of 4 versions of a…

This study examined the construct validity of the Rod and Frame Test (RFT). Subjects were 554 clients (269 males and 285 females) (aged 14 to 65 years) of the Johnson O'Connor Research Foundation (JOCRF), a vocational guidance service. In a battery of diverse ability and style tests (19 tests of the JOCRF battery and 4 tests of cognitive style),…

One purpose of this research is to develop models of cognitive processes in understanding mechanical systems. A particular focus was on the processes in mentally animating the representation of a mechanical system, and the contribution of animation graphics in comprehension. Several studies, involving eye fixations, verbal protocols, and process…

This dissertation presents the results of an investigation of visual mental imagery as a strategy hypothesized to increase the amount of interaction with content material and therefore the level of information processing and acquisition, and to assist information retrieval on posttests. Four treatments were used in a crossed, randomized two by two…

Three-dimensional (3-D) aerial photographs viewed with cardboard filter glasses (anaglyphs) aid elementary and junior high school students in recognizing physical features, offer a realistic vertical perspective, and have motivational values. A review of research on cognition, perception, and the use of anaglyphs reveals that pictures are an…
