Online Mathematics Homework Increases Student Achievement, Jeremy Roschelle, Mingyu Feng, Robert F. Murphy, Craig A. Mason

STEM Faculty Scholarship

In a randomized field trial with 2,850 seventh-grade mathematics students, we evaluated whether an educational technology intervention increased mathematics learning. Assigning homework is common yet sometimes controversial. Building on prior research on formative assessment and adaptive teaching, we predicted that combining an online homework tool with teacher training could increase learning. The online tool ASSISTments (a) provides timely feedback and hints to students as they do homework and (b) gives teachers timely, organized information about students’ work. To test this prediction, we analyzed data from 43 schools that participated in a random assignment experiment in Maine, a state that provides …

Discussion In Middle And High School Earth Science Classrooms And Its Impact On Students' Abilities To Construct Evidence-Based Arguments In Their Written Work, Rachel Martin

Electronic Theses and Dissertations

Middle and high school teachers who participate in the Maine Physical Sciences Partnership (MainePSP) noted persistent problems in their classrooms, including low levels of student engagement and gaps in how students use evidence. To address these problems, this study was designed in collaboration with MainePSP teachers in a design-based implementation research process as teachers aimed to better connect classroom discussion and written argumentation. Though scientific writing makes use of argumentation to support ideas, it is often the sharing of ideas that makes an argument stronger.

Two teachers collected data from their seventh and ninth grade Earth Science classrooms at schools …

Calculus Students' Reasoning About Slope And Derivative As Rates Of Change, Jennifer G. Tyne

Electronic Theses and Dissertations

Students’ low success rates in college calculus courses are a factor that leads to high attrition rates from science, technology, engineering and mathematics (STEM) degree programs. To help reach our nation’s goal of one million additional STEM majors in the next decade, we must address the conceptual difficulties of our students. Studies have shown that students have difficulty with the concepts of slope and derivative, especially in cases when students are asked to utilize these concepts in real-life contexts.

For this study, written surveys were collected from 69 differential (first semester) calculus students. Follow-up clinical interviews were performed on 13 …

Inconsistent Conceptions Of Acceleration Contributing To Formative Assessment Limitations, Gregory D. Kranich

Electronic Theses and Dissertations

Science, technology, engineering, and mathematics (STEM) education has become a national priority in light of measures indicating marginal student interest and success in the United States. Just as evidence is integral to policy decisions, so too do teachers depend on evidence to inform instructional choices. Classroom assessment remains a touchstone means of gathering such evidence as indicators of students’ progress, and increasingly, teachers are designing, implementing, and interpreting assessments in collaboration with one another.

In rural Maine, the work of the Maine Physical Sciences Partnership (MainePSP) has enabled science educators to come together as a supportive professional community. We focused …
