The purposes of the study were / to investigate the effect of type of high school on spatial ability, to investigate the relationships between students&rsquo / mathematics achievements, logical thinking abilities and their spatial abilities and to investigate the effect of technical drawing course on the development of students&rsquo / spatial abilities. The study was conducted in Ankara with 251 9th-grade students who enrolled to general, Anatolian, foreign language, commercial vocational and industrial vocational high schools. Two measuring instruments were utilized: Spatial Ability Tests and Group Test of Logical Thinking. Spatial Ability Tests, which were developed by Ekstrom, consist of card rotation, cube comparison tests measuring the spatial orientation ability and paper folding and surface development tests measuring the spatial visualization ability. The tests were translated in to Turkish by Delialioglu, (1996). Group Test of Logical Thinking was developed by Roadrangka, Yeany, and Padilla and a Turkish version of GALT was developed by Aksu, Beberoglu and Payko&ccedil / (1990). In order to analyze the obtained data, one way ANOVA, correlation analysis and t-test were used. The results of the study indicated that / there is no significant effect of type of high school on students&rsquo / spatial abilities / there is a significant positive relationship between spatial ability and mathematics achievement / there is a significant positive relationship between spatial ability and logical thinking ability / there is a significant positive relationship between spatial ability and technical drawing achievement / and there is a significant development in the students&rsquo / spatial abilities of the students in the technical drawing course.

Earlier studies have shown that the use of computer or physical visualization tools result in a more efficient learning of these concepts. It is believed that part of the positive effect is related to training visual-spatial abilities. Based on these studies, this research sought to investigate the impact of an educational intervention on the accomplishments of tasks that measure visual-spatial abilities. A group of 56 students paired by gender was divided randomly into two groups. One of the groups received an educational intervention using a kit for building a tetrahedron; the other group received a list of exercises of molecular geometry. To evaluate the effects of the proposed intervention, students were asked to take part of two mental rotation tests of three dimensional images after each intervention. In one of them, the stimuli were images of molecules, and in the other they were solid three dimensional objects; the images appeared at different rotations on a computer screen. The task was to say the name of the molecules and, in the case of the objects, compare them to other objects that had not been rotated. The tests were applied using equipment that registers eye movements (Tobii® 1750). The analysis was based on response time, right answers, wrong answers, and strategies of eye movement to follow stimuli. The main results showed a larger number of right answers in the group that used the kit, both in the test with images of molecules and in the test of geometric objects. These results lead us to believe that the kit was effective for the visualization of molecules, becoming an important teaching tool in Chemistry. Besides, the effect of the kit in tests of three dimensional objects pointed out to the positive impact that this strategy had on the visual-spatial abilities in general. / Uma das dificuldades encontradas no ensino da Química é o estabelecimento de relações entre representações do nível microscópico e as do macroscópico na exploração de um conceito. Estudos anteriores mostraram que a utilização de ferramentas de visualização computacional ou física resulta em aprendizado mais efetivo de conceitos. Acredita-se que parte do efeito positivo deva estar relacionada a um treinamento de habilidades visoespaciais. Para verificar essa hipótese, um grupo de 56 alunos pareados por gênero foi dividido aleatoriamente em dois grupos. Um dos grupos recebeu intervenção educacional com o kit de montagem física de um tetraedro; o outro recebeu uma lista de exercícios de geometria molecular. Para a avaliação dos efeitos das intervenções propostas, após essas intervenções os alunos realizaram testes de rotação mental de figuras tridimensionais. Em um deles, os estímulos eram figuras de moléculas e, no outro, eram objetos sólidos tridimensionais; as figuras apareciam rotacionadas em uma tela de computador. A tarefa era dizer o nome das moléculas e, no caso dos objetos, compará-los com outros objetos não rotacionados. Os testes foram realizados em equipamento de registro dos movimentos oculares (Tobii® 1750). Foram analisados o tempo de resposta, o número de acertos e erros, e as estratégias visuais de rastreio dos estímulos. Os resultados sinalizaram que o uso do kit foi efetivo para melhor visualização de moléculas, o que o caracterizou como importante ferramenta no ensino-aprendizagem de Química. Além disso, o efeito do kit em testes de figuras tridimensionais apontou para o impacto positivo que esta estratégia teve nas habilidades visoespaciais de forma geral.

Indiana University-Purdue University Indianapolis (IUPUI) / All branches of anatomy (gross anatomy, histology, neuroanatomy, and embryology) involve significant amounts of visual identification. Understanding the spatial relationship and visual representations of anatomical structures forms the basis for much of anatomy education, particularly in laboratory courses. Students in these courses frequently struggle with the visual aspects of identification, and many lack the metacognitive awareness to identify this problem. The research presented here details a series of experiments designed to elucidate the factors involved in students’ difficulties with studying the visual aspects of anatomy. All of the research projects discussed involved surveying students about their specific study habits. Student populations surveyed include first-year medical students and undergraduates in anatomy, physiology. These populations were surveyed about their study habits in each course, and their level of familiarity with visual learning. Additionally some populations were given a mental rotation test to assess their spatial abilities. These survey data were then correlated with course grades in an effort to determine the most successful study strategies. Active learning approaches (including student-produced drawings) were most strongly correlated with high course grades. However, efforts to teach lower-performing students active learning skills did not produce significant results, possibly due to the lack of a metacognitive component in this instruction. The results of each project indicate a lack of good study skills among students at all levels of anatomy instruction, and highlight the need for more instruction in how to study for anatomy, including metacognitive awareness, especially focused on the visual aspects of the course.

Bakgrund Människor behöver dagligen använda sitt spatiala (rumsliga) tänkande. Allt från att hitta saker hemma till att upptäcka saker i världen, för att navigera och att kommunicera. På liknande sätt används denna förmåga för att föreställa sig nya saker och skapa relationer mellan begrepp. Studien i detta arbete har visat att det finns bevis för att personer som studerar teknik och naturvetenskapliga ämnen har mycket att vinna på att förbättra sina spatiala förmågor. Den hittar bevis i tidigare forskning för att personer med bra spatiala förmågor också presterar bra i tekniska- och naturvetenskapliga yrken. Det visar sig också att förmågan går att öva upp och därför kan man diskutera vidare kring frågan om det skulle vara till gagn för svenska elever att öva upp förmågan för att de skall bli duktigare i skolan? Syfte Frågan ovan täcker ett stort område och kräver mycket forskning. I denna studie begränsas frågeställningen till att undersöka om det föreligger en korrelation mellan spatiala förmågor och resultat i matematik. Litteraturen talar också om att det är skillnad på mäns och kvinnors spatiala förmågor varför den kort också tittar på genusskillnader. Metod Undersökningen i denna studie har använt en kvantitativ metod och är en observation av resultat av ett spatialt test samt matematikbetyg. Studien består av en litteraturgenomgång och en empirisk studie i form av ett spatial test. 67 elever i årskurs ett, två och tre på gymnasiet utfört en webbaserad spatialt test för att bedöma deras spatiala förmågor. Resultat Litteraturgenomgången visar på att det finns en korrelation mellan en persons spatiala förmågor och bra resultat i olika tekniska och naturvetenskapliga ämnen. Analysen i den empiriska studien gav lite olika resultat. Till exempel kan man se att det sammanslagna resultatet av alla tre klasser ger en svag korrelation men är inte statistiskt signifikant. Uppdelat per klass kan man finna att det, i klass tre, finns en ganska svag korrelation som är statistiskt signifikant. Studien visar således inte på något generell korrelation, förutom en lite svagare korrelation i två undergrupper. Slutsatsen man bland annat kan dra av denna studie är att underlaget är för litet, 67 elever, och begränsad till endast en skola. Den tidigare forskningen är också begränsad till studier gjorda i USA och till största del på studenter på högskola eller universitet. Ytterligare forskning borde göras i en svensk kontext. / Background People need to use their spatial thinking daily. Everything from finding things at home to discovering things in the world, to navigate and to communicate. Similarly, this ability is used to imagine new things and to create relationships between concepts. This study will show that there is evidence that people studying engineering and science subjects have a lot to gain from improving their spatial abilities. It finds evidence in previous research that people with good spatial abilities also perform well in engineering and science. It also turns out that this ability can be trained and it is therefore interesting to discuss the question whether it would be beneficial for Swedish students to practice the ability to improve their performance in school. Purpose The topic and the question above requires a lot of research, in order to provide a good answer. In this study, the question is limited to if there is a connection between spatial abilities and mathematical results. The literature also tells us that there is a difference in the spatial ability of men and women, why there is a brief discussion at gender differences. Method The study has been carried out using mainly a quantitative method and is an observation of the results of a spatial test and mathematical grade. The study consists of a literature review and an empirical study in the form of a spatial test. 67 students in grade one, two and three in high school have undergone a web-based spatial test to assess their spatial abilities. Results Literature review shows that there is a correlation between a person's spatial abilities and good results in various technical and natural sciences. The analysis here gave a little different result. For example, the combined result of all three classes gives a weak correlation, which is not statistically significant. Dividing the students into subgroups based on grade, a fairly weak correlation was found for grade three that was statistically significant.
