IQWST ® (Investigating and Questioning our World through Science and Technology), which transforms adolescents into scientists, was developed over a decade by science education, literacy, and learning science specialists from the University of Michigan,Northwestern University, Michigan State University, and the Weizmann Institute of Science, supported by funding from the National Science Foundation. Students investigate questions relevant to their lives by conducting investigations; collecting and analyzing data; developing and using models to explain phenomena, and engaging in argument from evidence, all in a literacy and discourse-rich environment.
Lessons are organized into thematic units such as Can I Believe My Eyes? (Physical Science) and What’s Going on Inside Me? (Life Science), that support students as they build understanding of core ideas in science as well as understanding and use of scientific practices. Students also pursue their own original questions in units that integrate the fundamentals of Physical Sciences, Life Science, and Earth & Space Science.
As research indicates, and the Framework for K-12 Science Education and NGSS describe, students learn best when they use coherent materials that support them in building understanding over time.
- Sixth-graders learn about species interactions in ecosystems by investigating data from real-world examples of invasive species.
- Seventh-graders explore properties, chemical reactions, and the conservation of mass by making their own soap materials they have investigated across multiple lessons.
- Eighth-graders race, jump, and crawl in the classroom to measure properties of motion and create graphs based on physics equations.
- Eighth-graders use a computer program to investigate a drop in the Galapagos Islands’ finch population.
By referencing real-world science with which students are familiar or have personal experience, science learning has value to diverse students who can apply what they are learning to their everyday lives. Our learning-by-doing pedagogical approach — paired with the expertise of our Chief Learning Officer Dr. LeeAnn Sutherland, Michigan State Professor Joe Krajcik, Northwestern University Professor Brian Reiser, and Weizmann Institute Senior Scientist David Fortus — engages students as active learners and makes science come alive in ways that research has shown best support the broad range of learners found in every classroom.
CLAIM, EVIDENCE & REASONING (CER)
Every science teacher understands the value of students being able to explain phenomena, not simply to define vocabulary words or to answer questions that require them to show what they have memorized. But teaching students to construct explanations is challenging.
IQWST makes the process easier by supporting teachers and students with a systematic approach that includes the now well-known CER framework. The framework divides explanations into three logical, manageable, and teachable components for middle school students: Claim, Evidence, and Reasoning.
We developed the CER framework alongside teachers who were frustrated by their students’ responses to oral and written questions—typically responding in such brief ways that teachers could not adequately assess their students’ understanding. The CER framework was born and developed in IQWST as a result of teachers’ desire to better support their students as scientific thinkers and writers.
To begin, students must be asked questions that require them to think deeply about what they have observed, read, and experienced and to integrate that information as they explain the how or why of phenomena for a specific purpose and audience. Although an explanation must function as a whole, teachers often find it easier to teach the components separately and explicitly.
A claim is a statement of a student’s understanding about a phenomenon or about the results of an investigation; it answers the original question by expressing what he or she is trying to help an audience understand and believe. In practice, teachers often teach that a claim cannot begin with “yes” or “no,” and is typically the first sentence of an explanation.
Although a claim does not need to be the first sentence in an explanation, it is helpful for students to learn to construct explanations with specific guidelines that can be varied later. The claim is typically the part of an explanation that students find easiest to include and to identify as they critique others’ explanations. Claims may be made about data that students have been given or that they have gathered themselves. If an investigation has independent and dependent variables, the claim describes the relationship between them. The quality of an explanation is largely dependent on a good question to begin with, so consider first the question. After an investigation, have students return to that question, and their response, in a sentence, is typically a claim.
While data can refer to all the observations that students have collected or analyzed, data become evidence when used to support a claim. A claim is convincing to someone else only when there is strong evidence to support it.
The evidence for explanations can come from investigations students conduct, from observations they make, or from reports of empirical research others have done. In complex situations, more than one claim might be made about a single data set thus having accurate, appropriate, and sufficient evidence is what makes a claim convincing. The idea that multiple claims might be made using the same data develops across the IQWST curriculum as the inquiry activities become more complex, and students’ options for research questions (and resulting claims and evidence) become increasingly open ended. One challenge of the evidence component is that students assume they do not need to describe the data because their teacher and classmates already know what happened! Thus, helping students to decide which data to choose and how to present those data as evidence is a key step in the process of learning to construct an explanation. Significant time must be devoted to helping students understand what counts as good evidence in science, drawn from qualitative and/or quantitative data, and what it means for evidence to be both appropriate and sufficient.
Reasoning is the most challenging for both students and teachers. Reasoning illustrates why particular evidence is the correct evidence to use in support of a particular claim. Reasoning typically includes describing the scientific knowledge or theory, or what IQWST refers to as the Scientific Principle, that applies to a particular claim and evidence. The principles are not given to students, but are “figured out” through their own investigations and in the context of whole-class discussions.
Reasoning requires students to make explicit the steps of their thinking, showing the logic that leads from the evidence to the claim. Critiquing examples of explanations helps students recognize the components and the need for them. They quickly learn to determine what is missing or inadequately expressed—and because they find this easier than constructing their own explanations, it is often a good starting point. Sharing an anonymous example from 3rd period with students from 1st period enables students to learn what to look for without feeling criticized early in the learning process. IQWST provides systematic scaffolding to guide students in constructing explanations of scientific phenomena, and to support teachers in facilitating this process. Using evidence and reasoning to construct explanations is one of the most important practices students can learn, with application beyond science class to high school, college, career, and citizenship readiness in all areas!
K-5 SCIENCE MODULES
Science explores physical, earth, and the life sciences. The curriculum is designed to provide your child with an understanding of the many aspects of our world and beyond. Throughout the course of the year we will be studying forces and motion, planetary science, organisms and their environment, and much, much more.
The following strategies and activities have been incorporated into the curriculum:
- Lab Notebooks (In class document)
- Lab Notebooks are a permanent record of students’ investigations and observations over the course of each quarter.
- Portfolios (In class document)
- The student portfolios contain rubrics, student reflections and questions about their work, progress, performance, and goals for the future.
- Essay Questions on Tests and Quizzes
- Students are formally assessed weekly or biweekly. Essay questions are also assigned for homework regularly.
- Integration of Mathematical Concepts and Graphing Skills
- Concepts and skills are integrated throughout all lessons, investigations and research.
- Out-of-Class Projects
- Project topics relate to our current units of study. These projects are very important — they will count as a major grade.
- Current Events Research (Opportunity for Extra Credit)
- An integral part of our class discussion, it helps connect real world events with the topics of study. Both student and teacher led, it is presented/shared in a variety of formats (printed articles, PowerPoint, etc.)
