Enhancing Scientific Literacy Through Multiple Text Genres

Science project-based curricula generally include the use of multiple tools
for inquiry (Krajcik, Blumenfeld, Marx, Bass, & Fredricks, 1998), but little
is known about how teachers and students employ print-based tools in the service
of classroom science inquiry projects. In particular, what are the effects
on student learning of textual tools designed with different forms of texts,
including expository, narrative, and real-world texts? How can teachers and
students use such textual tools most effectively in project-based science
learning? In this project, we address questions regarding the development
of general and scientific literacy skills by testing print-based tools specifically
designed to support students’ interactions with science-related textual materials
or tools as they engage in inquiry. We hypothesize that careful sequencing
of certain types of text forms or genres, including expository, narrative,
and naturally occurring texts, can support students’ learning of science concepts
and discourse. We will determine the features of textual tools that best support
middle-school students’ science and scientific literacy learning, thus providing
a model for the development of textual tools for different types of curricula.
- What effect do various combinations of text forms have on content and
literacy learning?
- Does the combination of constructed expository text with naturally
occurring text have a greater effect on student learning than the use
of constructed expository text alone?
- Does the combination of constructed expository text with constructed
narrative text have a greater effect on student learning than the use
of constructed expository text alone?
- Does the combination of constructed expository text with both naturally
occurring and constructed narrative text have a greater effect on student
learning than the use of constructed expository text alone?
- What is the role of curriculum readers in the classrooms under study?
- How do teachers use the readers and other print texts?
- How do students engage with the readers?
- How do teachers employ scientific literacy teaching strategies taught
in professional development? What effect do these strategies have on students’
content and literacy learning?
Primary data sources for the project include (a) pre- and post-test scores
on assessments designed specifically to address content knowledge (b) pre-
and post-test scores on assessments designed specifically to address reading
skills reflected in the curriculum; (c) standardized measures of students’
reading and writing ability levels; (d) student content and process interviews;
formal, unstructured interviews with students and teachers; informal reading
and writing inventories; naturalistic and predetermined observations of the
uses of literacy and various types of text; (e) naturally occurring artifacts
of student work; (f) artifacts designed to serve as reader activities and
as assessment measures. Contextual data sources include pre- and post-test
score data, observational data, and content and process interview data collected
across all classrooms in the larger research initiative. This study will provide
science and literacy researchers with the opportunity to develop the capacity
to design innovative science reading materials, literacy professional development
activities for teachers, and classroom enactments of literacy strategies that
advance scientific literacy and science concept learning.
