State University of New York at Buffalo
Research in Science & Technological Education Vol. 16, No. 2 (1998) pp. 177–202
Uses digraphing as methodology to synthesize students' conceptions of natural phenomena in order to identify the structural characteristics of their conceptions. Contains 41 references. (DDR)
Effects of Combined Hands-on Laboratory and Computer Modeling on Student Learning of Gas Laws: A Quasi-Experimental Study
Journal of Science Education and Technology Vol. 15, No. 1 (March 2006) pp. 89–100
Based on current theories of chemistry learning, this study intends to test a hypothesis that computer modeling enhanced hands-on chemistry laboratories are more effective than hands-on laboratories or computer modeling laboratories alone in...
The Dimensionality of Test Data Generated by Compensatory and Non-Compensatory Two-Dimensional IRT Models and Its Effect on Model-Data-Fit
The difference between compensatory and non-compensatory item response theory (IRT) models in terms of the dimensionality of test data generated by them, and its effect on the model-data-fit were examined. The STRESS (proportion of variance not...
Journal of Science Education and Technology Vol. 20, No. 4 (August 2011) pp. 375–387
This study examines the relationship between opportunity-to-learn (OTL) at home and students' attainment of science proficiency. The data set used was the 2006 PISA science US national sample. Data mining was used to create patterns of association...
Journal of Science Education and Technology Vol. 14, No. 1 (March 2005) pp. 101–116
This study investigates factors affecting the degree of novice physics students application of the naive impetus theory. Six hundred and fourteen first-year university engineering physics students answered the Force Concept Inventory as a pre-test...
Descriptive Categories and Structural Characteristics of Students' Conceptions: An Exploration of the Relationship
Research in Science & Technological Education Vol. 20, No. 1 (2002) pp. 111–32
Explores the relationship between the descriptive categories and structural characteristics of students' conceptions so that a theoretical framework may be developed to explain and predict students' alternative conceptions in science. The...
Journal of Science Education and Technology Vol. 17, No. 4 (August 2008) pp. 373–383
This article reports on an analysis of alignment between NY state core curricula and NY Regents tests in physics and chemistry. Both the curriculum and test were represented by a two dimensional table consisting of topics and cognitive demands. The...
Teachers, Computers, and the Internet: The First Stage of a Community-Initiated Project for the Integration of Technology into the Curriculum
Alberta Journal of Educational Research Vol. 43, No. 4 (1997) pp. 222–34
A study examined the reactions of Canadian secondary school teachers to the rapid introduction by a community group of a school computer laboratory connected to the Internet. Observation, surveys, and interviews revealed a lack of district policy on ...
Science Education Vol. 90, No. 4 (July 2006) pp. 579–604
Holding the premise that the development of expertise is a continuous process, this study concerns expert models and modeling processes associated with a modeling tool called Model-It. Five advanced Ph.D. students in environmental engineering and...
McGill Journal of Education Vol. 33, No. 1 (1998) pp. 51–69
Observes secondary school students' use of computers for learning. Identifies limited use of computers for learning by students, dependency of students on teachers for integration, and constraints of teachers on students in terms of teachers'...
Understanding the Life Cycle of Computer-Based Models: The Role of Expert Contributions in Design, Development and Implementation
Educational Technology Research and Development Vol. 63, No. 6 (2015) pp. 831–859
This paper examined the nuances of the background process of design and development and follow up classroom implementation of computer-based models for high school chemistry. More specifically, the study examined the knowledge contributions of an...
Using Rasch Measurement to Develop a Computer Modeling-Based Instrument to Assess Students' Conceptual Understanding of Matter
Journal of Chemical Education Vol. 89, No. 3 (February 2012) pp. 335–345
Research suggests that difficulty in making connections among three levels of chemical representations--macroscopic, submicroscopic, and symbolic--is a primary reason for student alternative conceptions of chemistry concepts, and computer modeling...
Journal of Computers in Mathematics and Science Teaching Vol. 31, No. 3 (July 2012) pp. 259–281
This paper reports a feasibility study on developing computer model-based assessments of chemical reasoning at the high school level. Computer models are flash and NetLogo environments to make simultaneously available three domains in chemistry:...
Teacher Conceptions and Approaches Associated with an Immersive Instructional Implementation of Computer-Based Models and Assessment in a Secondary Chemistry Classroom
International Journal of Science Education Vol. 36, No. 3 (2014) pp. 467–505
This paper reports on a case study of an immersive and integrated multi-instructional approach (namely computer-based model introduction and connection with content; facilitation of individual student exploration guided by exploratory worksheet; use ...
