UNIT TEMPLATE: Text-Based STEM Inquiry

This template provides an approach for creating a science investigation that includes reading-focused inquiry to build student science literacy skills. The template was created to support library media specialists and STEM teacher cohorts in the School Librarians Advancing STEM Learning project, led by the Institute for the Study of Knowledge Management (ISKME) in partnership with Granite State University, New Hampshire, and funded by the Institute for Museum and Library Services (IMLS).


Part I: Unit Title: Evaluate This! Drawing Conclusions with Statistics

Part II: Background on LMS and Science Teacher relationship :  This lesson was created by Library Media Specialist Kim Carter and mathematics teachers Alaura Carson and Jen Spoerke.  Jen’s strengths include selecting standards and subjects that are suitable for literacy lessons particularly with integrating writing in math.  Alaura’s strengths are mathematical content knowledge and a willingness to collaborate. Kim’s strengths are inquiry-based instructional design, curation of resources, and knowledge of open-source materials.

Jen is interested in learning more about OER, how to share and organize resources for others’ uses, and how to integrating reading in math. Alaura is interested in learning how to incorporate literacy in a mathematics class.  Kim is interested in learning more about the statistics content and skills and how Alaura and Jen scaffold students’ conceptual understanding and practical applications.

Part III: Unit Description: This unit includes 10 unit days and our blocks are 90-minutes long. Through the interpretation of making inferences and justifying conclusions based on statistical data, students will come to a better understanding of mathematical evidence and reason.  Our lessons will culminate in students presenting their findings comparing local to national data regarding the relationships between educational attainment and financial earnings. Students will have options for different presentation media (web-based, face to face, pamphlet, etc.) and audiences (peers, parents, community members). Over the course of the unit, students will explore a variety of texts and grow in their knowledge of data collection and evaluation to write their own report.

Part IV: Standards

CCSS Mathematics Standards

  • Make inferences and justify conclusions while evaluating reports based on data.
  • Make inferences and justify conclusions from sample surveys, experiments, and observational studies (http://www.corestandards.org/Math/Content/HSS/IC/)

CCSS.MATH.CONTENT:  HSS.IC.B.6 : Evaluate reports based on data.

CCSS Mathematical Practices

  • Reason abstractly and quantitatively.
  • Look for and make use of structure.

CCSS Science Literacy Standards

  • CCSS.ELA-LITERACY.RST.9-10.7: Translate quantitative or technical information expressed in words in a text into visual form (e.g., a table or chart) and translate information expressed visually or mathematically (e.g., in an equation) into words.

Part V: Unit Essential Question:  What inferences and/or conclusions can be drawn from relationships between data sets?

Part VI: Goals for Using Inquiry: The goal for using inquiry in this unit is to have students make inferences and draw conclusions based on data and select their own additional resources to develop an answer to the unit’s essential question.  The math teachers and the media library specialist have selected an anchor text presenting statistical data on educational attainment and annual earnings of young adults. Supporting texts provide resources for students to further consider when making personal meaning of statistical data.

The goal for using inquiry in this unit is to have students examine the anchor text as an open invitation to inquiry about drawing conclusions from statistical data.  Using the anchor text “Annual Earnings of Young Adults” (NCES, 2016) as the base and 2 supportive texts, including “3 Ways to Spot a Bad Statistic” and  Community Profiles for each campus’s city (Keene and Manchester), students will develop their own set of inquiry questions (ex: “I wonder…”) for a comparing local data to the national data presented in the anchor text.  Students will narrow down their inquiry questions to one specific, targeted question that they seek to answer through the culminating activity.

Part VII: Summative Assessment Description and Rubric

Summative Assessment - Students will find local data similar to the supporting text and draw conclusions from the data.  Students will make inferences about why the data is or could be different by creating a report that highlights key data to support their conclusions.

Rubric -

 Research/Statistical Data  Students include 4 or more examples or pieces of data to support their claim from a reliable source.  Students include at least 3 examples or pieces of data to support their claim from a reliable source.  Students include at least 2 examples or pieces of data to support their claim from a reliable source.  Students include fewer than 2 examples or pieces of data to support their claim from a reliable source OR the examples or pieces of data to support their claim are from an unreliable source.
Sources - Citation   Information in all source citations is correct and in the format assigned. Information in all source citations is correct but there are minor errors in formatting.   Information in almost all source citations is correct AND there are minor errors in formatting.  Information in some source citations is correct OR there are major errors in formatting.
 Product  Students create an original, accurate and interesting product that makes a compelling case.  Students create an accurate product that makes a compelling case.  Students create an accurate product but it does not make a compelling case.  The product is not accurate.

Part XIII: Teacher and Librarian Reflection on the Implementation of the Unit

Kim Carter - Librarian: There were plenty of surprises for me in the implementation of our Unit, from our initial implementation to how students engaged with the unit context and tasks to the resulting outcomes.

Initial implementation: In retrospect my first surprise - my team members’ discomfort with teaching reading literacy strategies - shouldn’t have been a surprise at all and is likely more a measure of an unfortunate loss of perspective on my part as my role has decreased my direct connection with daily instructional practice. I honestly don’t know any math teachers who have been taught or have been expected to develop reading literacy instructional skills. Therein lies some of the obvious value of the collaboration! Unfortunately, my availability for co-teaching and collaboration beyond the planning process and the anchor text lesson was limited and I feel was not as effective a team member as I needed to be.

My availability also impacted my interactions with the students. Even though they all knew me, they were definitely not used to having me in their math class. One takeaway is that to be a full collaborator through implementation of the unit, the librarian partner should be involved throughout the unit, not just during the anchor text lesson.

Student Engagement : Generally speaking, students are both MC2 campuses attend MC2 because they want an alternative to traditional classes. Classes are called learning studios with the idea that they’ll be project- and problem-based, a concept that can be a bit more challenging for math curriculum. Add to that the fact that all MC2 learning studios are heterogeneous, across ages and abilities. While students select the learning studios they want, they also have to pay attention to credits they need. All of the above is to say, students in MC2 learning studios are pretty immediate in communicating (verbally or nonverbally) whether or not learning activities are engaging them.

Observations from the anchor text lesson include:

  •  Many students were startled that they were being expected to read an article.
  • The focus topic we selected - the relationship between educational attainment and financial earnings - missed the mark. Students at each campus were more intrigued by the gender differences in earnings than the relationships to educational attainment (a couple pursued this question in their personal projects.)
  • Virtually all students were highly engaged by Supporting Text #1 - 3 Ways to Spot a Bad Statistic. Starting with this engaging video/transcript combination may more successfully hook students into the subsequent anchor text work  It would also be worth considering using the combination of the video with its transcript as the anchor text itself.

Resulting Outcomes : While many students completed the tasks for the unit, fewer students completed the final projects. The students who did complete the work and wrote their final reflections noted skepticism of the value of the use of the anchor text and the explicit close reading activities. One student commented:  “While I get the two [subjects] are connected, that is no excuse for sliding from subject to subject.”  

  Overall, I think we need to do a better job integrating and scaffolding literacy activities within our math instruction. Using high-interest topics to establish purpose and meaning for the use of the texts is particularly important with our often less than confident learners.

Jen Spoerke - Math Teacher

This unit was a challenge to incorporate into the class that we were teaching.  I thought it was going to slide in with minimal disruption, but we moved slower through unit 1 then we were expecting to, so unit 2 (this unit) didn’t get as much build up as we were hoping which resulted in a rough introduction.

As a math teacher, I have never been taught how to teach literacy skills.  I expect that kids come into my class with basic literacy skills that I can help them hone in the context of mathematics.  I was very glad to have Kim come in to teach the literacy lesson because I would have botched if left to my own devices.

The kids struggled with the fact that they were expected to read and analyze a text.  They also struggled with the notion of going back to the text again and again.  It is a trend that I’ve noticed within academia (and I am guilty of it myself) that students are not thrilled with the idea of mingling different subject areas together.  This was very apparent in this particular statistics class; many of the students lost interest in the class and few completed the final project.

I think it would have been helpful to have Kim involved for a longer period of time.  When the kids began writing their report, it would have been great to have her there to tap into her literacy skills.  I can let someone know that what they’ve written sounds weird, but not why or how to fix it.

If this unit is used again in the future, I think there needs to be a more solid connection to the previous unit and better differentiation for various literacy skills.

Alaura Bailey (Carson) - Mathematics Teacher

Planning this unit made me realize how much I miss being able to collaborate with other mathematics teachers and bounce ideas off of them when planning a unit.  It was great to be able to work with Jen and share in the joy and struggles of planning the unit leading up to Evaluate This.  We were able to share what went well with each other and change lessons as needed when one did not go as expected.  It was great being able to work with Kim as well and having the library media specialist as another sounding board.  However, it was difficult to collaborate cross campus with about 60 miles between us.

Having a template to follow was great.  However, at points is was difficult to work with.  I found it to be beneficial and a challenge to select the anchor text before beginning to plan the unit.  We really had to think about the big picture of the unit when picking the anchor text.  I also found the time constraints when of when the SLASL unit had to be taught a challenge.  It made me feel as if some of the lessons leading up to the SLASL unit were rushed and not covered as well as I would have liked.

It was interesting watching the students learn from mistakes that they made when creating the survey.  They wanted to leave many of the questions such as level of educational attainment as short responses rather than multiple choice.  This lead them to have to interpret what some of the responses (such as 13 years of schooling or OJT) meant in terms of educational attainment.  

I am glad that I had the experience of helping to create a text based unit and do see the value in doing so again in the future.  One of the most eye opening realizations for me was that there were even literacy standards for technical subjects.  Now that I am aware of them, I will be more conscientious of them when planning future units.
