Title: Using computational thinking for data practices in high school science.
When conducting a science investigation in biology, chemistry, physics or earth science, students often need to obtain, organize, clean, and analyze the data in order to draw conclusions about a particular phenomenon. It can be difficult to develop lesson plans that provide detailed or explicit instructions about what students need to think about and do to develop a firm conceptual understanding, particularly regarding data analysis. This article demonstrates how computational thinking principles and data practices can be merged to develop more effective science investigation lesson plans. The data practices of creating, collecting, manipulating, visualizing, and analyzing data are merged with the computational thinking practices of decomposition, pattern recognition, abstraction, algorithmic thinking, and automation to create questions for teachers and students that help them think through the underlying processes that happen with data during high school science investigations. The questions can either be used to elaborate lesson plans or embedded into lesson plans for students to consider how they are using computational thinking during their data practices in science.  more » « less

  1. The purpose of this study was to investigate how computational modeling promotes systems thinking for English Learners (ELs) in fifth-grade science instruction. Individual student interviews were conducted with nine ELs about computational models of landfill bottle systems they had developed as part of a physical science unit. We found evidence of student engagement in four systems thinking practices. Students used data produced by their models to investigate the landfill bottle system as a whole (Practice 1). Students identified agents and their relationships in the system (Practice 2). Students thought in levels, shuttling between the agent and aggregate levels (Practice 3). However, while students could think in levels to develop their models, they struggled to engage in this practice when presented with novel scenarios (e.g., open vs. closed system). Finally, students communicated information about the system using multiple modalities and less-than-perfect English (Practice 4). Overall, these findings suggest that integrating computational modeling into standards-aligned science instruction can provide a rich context for fostering systems thinking among linguistically diverse elementary students.

  2. In recent years, Wyoming has developed Computer Science (CS) standards for adoption and use within K-12 classrooms. These standards, adopted in January of 2022, go into effect for the 2022-2023 school year. The University of Wyoming has offered two different computer science week-long professional developments for teachers. Many K-12 teachers do not have a CS background, so developing CS lessons plans can be a challenge in these PDs.This research study is centered around three central questions: 1) To what extent did K-12 teachers integrate computing topics into their PD created lesson plans; 2) How do the teacher perceptions from the two CS PDs compare to each other; and 3) How was the CS PD translated to classroom activity? The first PD opportunity (n=14), was designed to give hands-on learning with CS topics focused on cybersecurity. The second PD opportunity (n=28), focused on integrating CS into existing curricula. At the end of each of these PDs, teacher K-12 teachers incorporated CS topics into their selected existing lesson plan(s). Additionally, a support network was implemented to support excellence in CS education throughout the state. This research study team evaluated the lesson plans developed during each PD event, by using a rubric on each lesson plan. Researchers collected exit surveys from the teachers. Implementation metrics were also gathered, including, how long each lesson lasted, how many students were involved in the implementation, what grades the student belonged to, the basic demographics of the students, the type of course the lesson plan was housed in, if the K-12 teacher reached their intended purpose, what evidence the K-12 teacher had of the success of their lesson plan, data summaries based on supplied evidence, how the K-12 teachers would change the lesson, the challenges and successes they experienced, and samples of student work. Quantitative analysis was basic descriptive statistics. Findings, based on evaluation of 40+ lessons, taught to over 1500 K-12 students, indicate that when assessed on a three point rubric of struggling, emerging, or excellent - certain components (e.g., organization, objectives, integration, activities & assessment, questions, and catch) of K-12 teacher created lessons plans varied drastically. In particular, lesson plan organization, integration, and questions each had a significant number of submissions which were evaluated as "struggling" [45%, 46%, 41%] through interesting integration, objectives, activities & assessment, and catch all saw submissions which were evaluated as "excellent" [43%, 48%, 43%, 48%]. The relationship between existing K-12 policies and expectations surfaces within these results and in combination with other findings leads to implications for the translation of current research practices into pre-collegiate PDs.

  3. Oftentimes engineering design tasks are thought of as acultural and devoid of community inclusion and values. However, engineering design is inherently a cultural endeavor. Problems needing engineering solutions or design thinking are situated in a specific community and need community solutions. This work in progress paper describes initial efforts from a project to help elementary and middle school teachers create culturally relevant engineering design tasks for implementation in their classrooms. To integrate best practices for culturally relevant pedagogy, the engineering design framework developed by UTeach Engineering was adapted to specifically address community needs and cultural values. Changes to the framework also include culturally relevant instructional strategies for classroom implementation. To situate the engineering design steps within a culturally relevant framework questions involving communities and students’ cultural needs, values, and expectations were posed in each stage of the design process. A water filtration engineering design task was situated in the cultural concept of “Mni Wiconi” (Water is life in the Dakota language). This was taught in a summer professional development workshop for a cohort of elementary and middle school teachers, in rural North Dakota, with school districts comprised of large Native American student populations. Teachers adapted this design task for their individual classrooms and content areas (science, math, social studies, ELA) and implemented it in their classrooms in the fall of 2021. Additional support for teachers was provided with fall workshop days aimed at helping them with the facilitation of a culturally relevant engineering task. To integrate culturally relevant teaching and good engineering design tasks, the North Dakota Department of Public Instruction’s Native American Essential Understandings Teachings of our Elder’s website was used. This allowed teachers and students to have firsthand knowledge of how various science and engineering concepts are framed within the indigenous community. Professional development focused on how to situate culturally responsive teaching in engineering design. For example, in one of the school districts the water filtration task was related to increased pollution of a nearby lake which holds significant importance for the local Tribal Nation. In addition to being able to visibly witness the demand for cleaner water, the book “We are Water Protectors” written by Carole Lindstrom, was used to provide cultural grounding for the Identify and Describe stages of the engineering design framework. Case studies of how teachers incorporated the water filtration design task into their lesson plans are presented along with their suggestions on how to improve classroom implementation. Future work in the program includes teachers and their students developing engineering design tasks situated in their own communities and cultures.

  4. In an effort to deepen learning in K-12 science classrooms, there has been a national movement to integrate computational thinking (CT). The purpose of this phenomenographic study was to understand teachers’ perceptions of the function and usefulness of a task analysis and a decision tree tool designed to help them with integration. Teachers participated in a long-term professional development to improve their knowledge and application of CT and then developed lesson plans integrating CT into science investigations. To assist in the integration, teachers used the two unique tools. No one lesson plan or content area addressed all of the CT practices, but all CT practices were addressed in lessons across all four science areas. All 19 teachers found that the task analysis tool helped them to shift their lessons to a student-centered focus and helped them pinpoint data practices so they could systematically integrate CT practices. However, they expressed confusion over the amount of detail to document on the tool. Similarly, teachers found both benefits and barriers to the decision tree tool. Teachers found the decision tree tool to be useful in predicting the ways students may misunderstand a data practice and in reflecting on the level of accomplishment of students. However, teachers were sometimes uncertain with how to efficiently document complex student behaviors when engaged with data practices and CT. Implications for the use of the two lesson planning tools is discussed.

  5. Wyoming recently mandated that computer science instruction be provided in K-12 schools by 2022, and there is an urgent need for designing instruction that can integrate computer science into the teaching of other subjects. This project assembles a network improvement community comprised of partners from the University of Wyoming, community colleges, Wyoming school districts, the Wyoming Library System, the Wyoming Department of Education, and local software development firms. The community meets once monthly over the duration of the project to collaborate stakeholder agendas for meeting the project goals. The community enlists K-8 teachers from across the state to experience professional development and collaborate on integrating computer science into their instruction of STEM and social science topics. The project is producing units for teachers, who are implementing these units with support from master teachers and educational scholars. The community serves as a forum for teachers to debrief and learn from each other about ways to improve their instruction and design of the curricular units. Libraries in the state system act as partners for dissemination to rural areas of the innovative instructional approaches. WySLICE prepares 150 K-8 teachers and state librarians from all disciplines to integrate computer science into their teaching. The project is reaching almost half of all K-8 students in Wyoming. The research questions address how teachers use modeling practices as supports for student understanding of algorithms and coding in a variety of ways. The curricula involve cybersecurity as well as other topics relevant to measurement in mathematics and social studies topics that involve social concerns like voting. Data sources include teacher lesson plans and recordings of their instructional implementation, scoring of each of these according to a rubric, meeting notes of monthly meetings, and results from pre-post student assessments. The evaluation focuses on the meeting of project goals and the quality of the management of the network improvement community. This project is jointly funded by CS for All and the Established Program to Stimulate Competitive Research (EPSCoR). This work is supported by the National Science Foundation under DRL Grant #1923542 "CS For All:RPP - Booting Up Computer Science in Wyoming."
