The purpose of this study was to investigate the effect of the levels of group cooperation on students' achievement during a series of physical science laboratory activities. Six intact seventh grade physical science classes taught by two teachers, with each teacher instructing three classes, were selected from two middle schools....
Current reforms in science education advocate instruction which capitalizes on broad,
integrative understandings of a few underlying concepts. Such recommendations imply
that science teachers already hold integrated conceptualizations and will use such
understandings to guide practice. However, little research exists which delineates the
global content understandings of biology teachers (herein...
The purpose of this study is to examine the events and activities that
triggered strategic and large-scale changes in four community college based
Small Business Development Centers. A review of the literature in
organizational theory and community college education was used to form
an integrated conceptual scheme which could be...
The purpose of this study was to examine fifth,
seventh, and tenth graders' attitudes toward school and
classroom science by means of questionnaires and
interviews. In particular, the study hoped to determine
(a) if a relationship existed between these two attitudes,
(b) what relationship, if any, grade level, gender,
ethnicity,...
The purpose of this study was to examine whether teaching materials designed
around fourth graders' preconceptions effectively produced conceptual change about
light propagation. Four Taiwanese fourth-grade intact classes (194 subjects), taught by
two teachers, participated in this study. The experimental group was exposed to the
conceptual change materials (CCM), and...
The purpose of this study was to identify the management demands that may
be unique to science classrooms. The sample consisted of three biology teachers and
three language arts teachers from two high schools located within the same school
district. To establish a basic framework, two quantitative questions were addressed:...
A large body of research has examined how children enter the science classroom
with previously formed ideas about the content they will learn. These ideas influence how
the child interprets instruction. This study reversed the investigative focus by exploring
how children's ideas in science influence teaching. Specifically, the study examined...
Authentic assessment of visitor learning in museum settings is a challenging
endeavor. Evaluation literature includes very few studies that link adult visitors' behavior
to their learning. Multiple data collection methods in a naturalistic environment hold
great promise for increasing understanding of informal public education.
In 1997, Oregon State University's Hatfield...
This study assessed the influence of three history of science (HOS) courses on college students and preservice science teachers' conceptions of the nature of science (NOS), and examined whether participants who entered the investigated HOS courses with a conceptual framework consistent with current NOS views achieved more elaborate NOS understandings....
A large amount of research has been conducted that establishes that students
of all ages hold conceptions about a variety of science topics that are not in line
with accepted scientific beliefs. These preconceptions have been identified in a
variety of ways in research situations; this study focused on how...
