What does inquiry teaching mean to you?
Which of the following scenarios would best describe your approach in presenting a unit on the gas laws?
At the start of the gas unit, students are given balloons, hot plates, beakers, graduated cylinders, thermometers, pressure probes, syringes, etc. They are instructed to be creative while they record observations and manipulate the items to see what they can discover about gases.
The teacher explains the relationships among temperature, volume, and pressure of a gas. Students then design their own experiments to investigate each relationship, being careful to select and control variables.
Prior to being taught the gas laws, students are provided instructions in order to collect data relating volume and temperature, volume and pressure, and pressure and temperature. Then, by studying and analyzing the data, they begin to discover and construct their own understanding of relationships among the variables.
After presenting the relationships among temperature, volume, and pressure of a gas, the teacher provides students with instructions for collecting gas data. Students perform the experiments and verify that the mathematical relationships among variables are indeed true.

Frameworks for Inquiry: Overview of Project
Inquiry is an approach to learning where the learner constructs his own knowledge about how the world works by gathering data through any of the 5 senses and by making meaning of the interrelationships that exist. The learner gathers data to answer a question that is either posed by the learner or by the instructor. Inquiry learning is a process that is cyclical in nature and requires the student to be engaged as an active participant in his own learning process. The inquiry process emphasizes the learner’s process skill development as he interacts with science and the world around him. It is through these process skills that ANY learner at ANY age interacts with the natural and material world. These interactions lead the learner to new discoveries and understandings by forming mental models and frameworks that new knowledge and concepts can attach to, thereby strengthening and enlarging the individual's overall intelligence. The learner will not only gain science content knowledge with this program but will also use his process skills with increasing sophistication and improve “higher-order-thinking-skills” as he interacts with data through hands-on experiences.
High School Chemistry: An Inquiry Approach is specifically a Guided Inquiry approach that has been developed, improved upon and carefully sequenced with a specific goal in mind. This goal is for high school Chemistry students to derive the concepts contained within a two-year course sequence. The curriculum ensures the student success by starting off with a unit on simple measurement. This unit allows students to focus on how data is collected and analyzed so that meaning comes from the collected data. The course work then addresses chemistry concepts through a macroscopic lens and through the gas laws, progressing in a sequenced journey that parallels chemistry’s historical sequence of discovery and building on a student’s mental model of the particulate nature of matter. As the students work through the units, they continually revisit skills and concepts that are integrated into content that is presented later in the course.
Teachers who transform their teaching method and pedagogy with this guided inquiry style will find that they also will grow dramatically from the experience. Instructors will discover a deeper and broader understanding of the basic chemistry concepts and will learn new and better ways of relating course concepts to one another. Instructors will also discover that their guided inquiry approach to teaching has as much an impact on their students’ success in the course as their attitude and content knowledge. It is just as important for an instructor to aid in the development of formal reasoning patterns as it is to pass on course content. The classroom environment that encourages the use of data for conceptual development will cause the student to be more engaged and construct his own learning while increasing his affective domain, improving his energy and attitude toward learning. The student will internalize and integrate the information on his own to a much greater degree. This will transfer to other learning situations and will help improve success in other academic endeavors. The instructor and the learner will grow in content knowledge, higher order thinking skills, process skills and will become lifelong holistic learners.

Who were the...
Pioneers in Science Inquiry Education
Robert Karplus (1927-1990)
At age 32, Robert Karplus left his work as an outstanding theoretical physicist and pioneered the inquiry movement in science education. The work of Jean Piaget showed that children have to progress from concrete thinking to more formal thinking skills. Karplus was revolutionary in applying Jean Piaget’s work to developing new science curriculum. He worked to create curriculum where children construct, or build, their own mental models of science. He felt that effective teachers need to be aware of the reasoning patterns used by children. He developed a three-phase learning cycle, known as Exploration, Invention, and Discovery, emphasizing science study as hands-on experiences. In 1961 he started the Science Curriculum Improvement Study (SCIS) at the Lawrence Hall of Science on the University of California-Berkeley campus. His first education paper with J. M. Atkin in 1962 was entitled “Discovery or Invention?” He also created a film for SCIC in 1969 titled “Don’t tell me, I’ll find out.”
The following is a quote from his article “Science Teaching and the Development of Reasoning” in Journal of Research in Science Teaching, Vol. 14, No. 2, page 367:
“the formation of formal reasoning patterns should be made an important course objective (at least as important as the covering of a certain body of subject matter”
Another pioneer in Inquiry Science Education is Rodger W. Bybee, director emeritus of Biological Sciences Curriculum Study (BSCS). He was executive director of the National Research Council’s Center for Science, Mathematics, and Engineering Education (CSMEE) in Washington, D.C. Between 1986 and 1995, he was associate director of BSCS. He participated in the development of the National Science Education Standards, and from 1993 to 1995 he chaired the content working group of that National Research Council project.
BSCS’s instructional model expanded on Karplus’ three phases of learning. The model, developed in the late 1980’s, has five phases: engage, explore, explain, elaborate, and evaluate.
The BSCS model used a backward design process described by Grant Wiggins and Jay McTighe in Understanding by Design (2005). The educator starts with a clear statement about what students should learn, based on the content standards. Next, the educator needs to determine what will serve as acceptable evidence of student achievement (evaluation stage). Then, a decision is made about what learning experiences (engage and explore) would most effectively develop students’ knowledge and understanding of the targeted content. Further refinement and activities may result (elaborate).

What do the project data and results tell us about the effectiveness of inquiry teaching?
Do students get the chemistry content when using the High School Chemistry: An Inquiry Approach curriculum?
Our data suggests that they do. The American Chemical Society (ACS) California Chemistry Diagnostic Exam is a 44 question multiple-choice test designed to assess students’ chemistry content knowledge. Nine years of data have been collected. The first two years show data before the project began. The next three years indicate years in which the curriculum was used in pieces. The last four years indicate data for which the course was taught in its entirety using the High School Chemistry: An Inquiry Approach curriculum. For all nine years the average score was above the national average of 22, which suggests that the students are learning as much chemistry content in the High School Chemistry: An Inquiry Approach curriculum course as they were previously learning. The chart below displays these data.
Do students' thinking skills improve when their teachers use the High School Chemistry: An Inquiry Approach curriculum?
The data suggests they do. We pre- and post-tested our students using the Lawson Classroom Test of Science Reasoning (CTSR) and found significant gains in reasoning ability in groups that were exposed to the High School Chemistry: An Inquiry Approach curriculum. During the 2009-2010 school year we did a comparison study. Two teachers are long-term members of the Frameworks for Inquiry project. Both exclusively use the High School Chemistry: An Inquiry Approach curriculum materials developed by the project for their first-year chemistry class and both teach in Missoula high schools. The third teacher (the control) taught first-year chemistry for 25 years and does not use the High School Chemistry: An Inquiry Approach curriculum materials. All three groups of students in these classrooms took an online version of the CTSR in the fall of 2009 (pretest), and again in the spring 2010 (posttest).
The results of the Pre/Post testing are remarkable. Students in the High School Chemistry: An Inquiry Approach curriculum groups (N=57), (N=47), made an average 1.92 and 1.20 point gains respectively. This represents 12.8% and 8.1% increases in their average CTSR scores. In contrast the control (N=35) group made an average gain of 0.37 points representing a 2.5% increase. The average normalized gain (ANG)–a ratio of the percent gain to the maximum possible percent gain–was remarkably different also. The High School Chemistry: An Inquiry Approach curriculum groups ANG results were .519 and .298, respectively, indicating a medium effect on the students’ science reasoning skills. The control group ANG of .0657 indicates the course had no effect on students’ science reasoning skills. The results are summarized in the chart below.
During the 2010-11 school year we did another study involving 3 teachers. Again two of the teachers are long term members of the Frameworks for Inquiry project, and the third is not. All three teachers used the High School Chemistry: An Inquiry Approach curriculum exclusively for their first year chemistry classes. Again, all three groups of students took an online version of the CTSR in the fall of 2010 (pretest), and again in the spring of 2011 (posttest). Students in the three groups (N=79), (N=100), and (N=19) made an average 2.03, 1.11, and 1.80 point gains respectively. This represents a 22.9%, 12.4%, and 19.3% increases in their average CTSR scores. The ANG results were .330, .182, and .319 indicating that the curriculum had a medium affect on the students’ science reasoning skills. These results are significant because the N=19 group was taught by a non-project teacher who had very similar results in reasoning skills gains. The results are also summarized in the chart below.
The main point regarding this data is that curriculum materials developed as inquiry-based can have a profound effect on students’ science reasoning skills.
|Thinking Skills Gains Measured using the Classroom Test of Scientific Reasoning (CTSR)|
|Teacher||Project Teacher A||Project Teacher B||Non-project Teacher C||Project Teacher A||Project Teacher B||Non-project Teacher D|
|Control vs Treatment||Treatment||Treatment||Control||Treatment||Treatment||Treatment|
|CTSR Pretest mean (15 items)||11.3||11.0||9.3||8.85||8.92||9.35|
|CTSR Posttest mean (15 items)||13.3||12.2||9.7||10.87||10.03||11.15|
|Average normalized gain||0.519||0.298||0.0656||0.330||0.182||0.319|
Data from the first year of implementation of the project supports that even a small infusion of inquiry- based learning can impact student thinking skills. A preliminary study used Honors Chemistry students as the control group. Students in Honors Chemistry have stronger math skills than General Chemistry students. The treatment group, General Chemistry students, was given early versions of the first six units of High School Chemistry: An Inquiry Approach curriculum as part of their studies. The treatment group showed higher ANG than the control, despite their lower math abilities.
