The effects of cognitive style, method of instruction, and visual ability on learning chemical kinetics

Abstract

This manuscript has been reproduced from the microfilm master. TJMI films the text directly from the original or copy submitted. Thu£, some thesis and dissertation copies are in typewriter &ce, while others may be from any type of computer printer.The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or uidistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction.In the unlikely event that the author did not send UME a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion.Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand comer and continuing from left to right in equal sections with small overlaps. Each original is also photographed in one exposure and is included in reduced form at the back of the book.

Designing and evaluating an evidence-informed instruction in chemical kinetics

“…Due to its importance in the understanding of reaction processes, chemical kinetics is included in both school and university curriculum in most countries (Cachapuz and Maskill, 1987;Justi, 2002). There is some empirical data available on students' difficulties in learning chemical kinetics (De Vos and Verdonk, 1986;Cachapuz and Maskill, 1987;Justi, 2002;Lynch, 1997;Van Driel, 2002;Cakmakci et al, 2006;Cakmakci, 2010a). Students' ideas about chemical kinetics were often quoted in the studies focusing on chemical equilibrium (Hackling and Garnett, 1985;Quilez and Solaz, 1995;Van Driel et al, 1998;Van Driel and Gräber, 2002) and thermodynamics (Johnstone et al, 1977;Sozbilir, 2001;Goedhart and Kaper, 2002;Sozbilir and Bennett, 2006).…”

Research on learning difficulties associated with chemical kinetics is investigated and documented by some researchers (Cachapuz and Maskill, 1987;Lynch, 1997;Van Driel, 2002;Justi, 2002;Cakmakci, 2010a). The results showed that chemical kinetics was considered as a difficult concept to understand by both school and undergraduate students (Justi, 2002;Cakmakci, 2010a).…”

Developing and Using Conceptual Computer Animations for Chemistry Instruction

“…However, dynamic chemistry processes such as gas phase equilibrium, collisions of molecules, and electrochemistry are visually represented in these textbooks by static diagrams. Only a handful of studies report instructional strategies, techniques, or uses of technology that might prove successful in the remediation of chemistry misconceptions (12)(13)(14). Because students often have difficulty visualizing, understanding, and remembering how dynamic chemical processes occur, the use of computers to display dynamic motion offers a means to help students understand complex chemistry concepts (15)(16)(17).…”

Enseñanza de la cinética química por medio de simulaciones y aprendizaje activo

“…No obstante, la realidad es que el desarrollo de estas habilidades no se está implementando transversalmente en la enseñanza, especialmente en temas en que es importante su utilización, como es el caso de la cinética química. Este contenido se aborda en el grado décimo, en el que se han encontrado dificultades para su comprensión, debido al uso de metodologías tradicionales que no satisfacen las necesidades de aprendizaje de los estudiantes (Tejada, Chicangana y Villabona, 2013) y excluyen la experimentación, la utilización de las tic y la modelización científica como aspectos fundamentales en la enseñanza de la química (Cardellini, 2012;Kurt y Ayas, 2012;Lynch, 1997).…”
