The Development And Evaluation Of A Computer-Assisted Strategy Designed To Change Student Misconceptions About Chemical Equilibrium, Hassan Hameed Jan 1990

The Development And Evaluation Of A Computer-Assisted Strategy Designed To Change Student Misconceptions About Chemical Equilibrium, Hassan Hameed

Theses: Doctorates and Masters

The main aims of this thesis are twofold. First, to identify and describe misconceptions about chemical equilibrium held by Year-12 chemistry students in the Maldives. Second, to investigate the effects of using a computer-assisted instructional strategy in changing those misconceptions. A misconception idenfication test and an interview schedule developed by Garnett & Hackling (1984) were used to diagnose student misconceptions about chemical equilibrium. The remediation aspect of the study used a computer-assisted instruction (CAI) package. The package was designed in accordance with a model of conceptual change proposed by Posner, Strike, Hewson & Gertzog (1982). The CAI package consists of …

The Effects Of Prisms Learning Cycle Strategies On Achievement, Integrated Process Skills, And Attitudes Towards Physics Of High School Physics Students When Referenced To Kolb’S Learning Style Inventory, Michael P. Kelly Jan 1990

The Effects Of Prisms Learning Cycle Strategies On Achievement, Integrated Process Skills, And Attitudes Towards Physics Of High School Physics Students When Referenced To Kolb’S Learning Style Inventory, Michael P. Kelly

Dissertations and Theses @ UNI

This study asked the question: Is the gain in physics achievement, process skills, and attitudes toward physics, using the PRISMS teaching strategy, different among high school physics students in the four cognitive learning modes identified by the Kolb Learning Styles Inventory (LSI)? In this study a group of high school physics students were tested for gains in scores in the three areas mentioned in the statement of the problem. This treatment group was taught using PRISMS teaching strategies. Their learning styles were classified according to the Kolb LSI. The procedure followed for this study included administration of the Kolb LSI …

Undergraduate Elementary Education Students’ Understanding Of The Particulate Nature Of Matter, Pushpa Pandey Jan 1990

Undergraduate Elementary Education Students’ Understanding Of The Particulate Nature Of Matter, Pushpa Pandey

Dissertations and Theses @ UNI

This study was descriptive in nature and investigated preservice elementary teachers' understanding of the particulate nature of matter. Twenty-two sophomore elementary education majors were interviewed using the interview-about-events technique. Students were asked to observe and offer explanations for some common physical and chemical changes such as melting, evaporating, condensing, dissolving, and burning. Next, the students' model of matter was probed and they were asked to provide a description of each event using their conceptual model. The results indicated that the majority of students (82%) accepted that matter is made of particles. However, only 56% of these students believed that particles …

Undergraduate Elementary Education Students’ Concepts Of Light, Deborah Lynn Orr Jan 1990

Undergraduate Elementary Education Students’ Concepts Of Light, Deborah Lynn Orr

Dissertations and Theses @ UNI

The purpose of the study was to describe some ideas that future elementary school teachers have about light and shadows. Twenty-five freshmen and sophomores in elementary education were interviewed using the Interview-About-Instances technique developed by Osborne and Gilbert. Students were asked to explain specific instances of sources and non-sources of light, the distance light travels, and the role of light in vision. Students defined the word "shadow" and predicted where shadows could be in particular situations. The results of this study indicate that many students lack factual information or have misconceptions concerning light propagation. Fifty-six percent of the students in …
