Item Initiating change in students' achievement and alternative frameworks through a problem solving based instructional model.(1997-03-24) Chang, C. Y.; Barufaldi, J. P.The purpose of this study was to investigate the effects of a problem solving based instructional model on earth science students' achievement and alternative frameworks. Students' opinions toward the instructional method were also investigated. The investigations employed a pretest/posttest control group design to detect any significant change. The 172 participants enrolled in four earth science classes received six weeks of the problem-solving based instruction. Selected items from the Taiwan Entrance Examinations for Senior High School were used to measure achievement in Earth Science content. An instrument with open-ended questions was used to examine conceptual change while a 10-item Likert-type questionnaire was used to explore student opinions toward the instruction. Results of an analysis of covariance on achievement posttest scores revealed that the problem solving based instructional model did significantly improve the achievement of students, especially at the application level. A chi-square analysis on students' alternative frameworks measure indicated that students taught using the problem solving based instructional model experienced significant conceptual changes.

(Author/JRH)Item Earth science student attitudes toward a constructivist teaching approach in Taiwan(The National Association of Geoscience Teachers (NAGT), 1999-01-01) Chang, C. Y.; Hua, H. P.; Barufaldi, J. P.The notion of constructivism is serving as the underpinning for many of the current reforms in science education and has been one of the most influential themes in science education for the past 20 years. This study was designed to investigate the attitudes of earth-science students toward a constructivist teaching approach. Eighty-six ninth-grade students enrolled in two earth-science classes were chosen to participate in the study. A five point Likert-style questionnaire with ten items was administered to the participants to explore their opinions of this teaching method during a six-week intervention. Results of the affective-domain survey strongly suggest that the students held no particular attitudes toward this learning style; yet, they all expressed their understanding of the advantages of the constructivist teaching method in terms of helping them develop science-process skills, improving their thinking skills, and providing opportunities to apply their own ideas. In addition, we also found that student attitudes toward the teaching-learning approach demonstrated a degree of frustration. They realized the advantages of this instructional method; however, they did not view this type of instruction as being promising because it appeared the approach would not help them perform better on their forthcoming achievement tests.Item Inquiry teaching and its effects on secondary-school students' learning of earth science concepts(The National Association of Geoscience Teachers (NAGT), 1998-01-01) Mao, S. L.; Chang, C. Y.; Barufaldi, J. P.Item The use of a problem-solving-based instructional model in initiating change in students' achievement and alternative frameworks(Taylor & Francis (Routledge), 1999-01-01) Chang, C. Y.; Barufaldi, J. P.This study examined the effects of a problem-solving-based instructional model on Earth science students' achievement and alternative frameworks. The investigations employed a pre-test/post-test control group design to detect any significant change. The 172 participants enrolled in four Earth science classes received six weeks of the problem-solving-based instruction. Selected items from Taiwan Entrance Examinations for Senior High School were used to measure students' achievement in Earth science content. An open-ended question instrument was developed by the researchers to examine students' conceptual change. Results of an analysis of covariance on achievement post-test scores revealed that the problem-solving-based instructional model did significantly improve the achievement of students (p < 0.05), especially at the application level p < 0.05. A chi-square analysis on students' alternative frameworks measure indicated that students who were taught using the problem-solving-based instructional model did experience significant conceptual changes than did students who experienced the traditional-lecture type teaching method (p < 0.001).
