This research explores the interplay between students’ understandings of proportional and functional relationships. Approximately 90 students participated in an early algebra intervention in Grades 3– 5. Before the intervention and after each year of the intervention, we evaluated their understandings of proportional and functional relationships. Data revealed that among Grades 4 and 5 students who identified a correct function rule, a higher percentage were unsuccessful solving a proportional reasoning problem than those who were not able to identify a correct function rule. Namely, the data suggest that students’ development of functional thinking may interfere with their development of understanding proportional relationships.

From recursive pattern to correspondence rule Developing students abilities to engage in functional thinking
Stephens, Ana; İşler Baykal, Işıl; Marum, Tim; Blanton, Maria; Knuth, Eric; Murphy Gardiner, Angela (2012-11-01)
Third- through fifth-grade students participating in a classroom teaching experiment investigating the impact of an Early Algebra Learning Progression completed pre- and post-assessment items addressing their abilities to engage in functional thinking. We found that after a sustained early algebra intervention, students grew in their abilities to shift from recursive to covariational thinking about linear functions and to represent correspondence rules in both words and variables.
The effect of problem-based learning on the elementary students' achievement in genetics
Araz, Gülsüm; Sungur, Semra; Department of Elementary Science and Mathematics Education (2007)
The purpose of the study is to investigate the relative effect of problem-based learning (PBL) and traditionally designed science instruction (TDSI) on students’ academic achievement and performance skills in the unit of genetics after controlling for students’ prior knowledge, prior performance skills, reasoning ability, and learning approach. The sample consisted of 192 eight grade students from a public elementary school in Ankara. Four classes instructed by two science teachers were randomly assigned as...
The effect of instruction with analogy-enhanced model on ninth grade students' function achievement and attitudes toward mathematics
Akman, Caner; Bulut, Safure; Department of Secondary Science and Mathematics Education (2005)
This study was conducted to investigate the effect of analogy-enhanced instruction on students̕ achievement in function and attitudes toward mathematics. The study was conducted with 63 ninth grade students in one of the public high schools in Konya, Turkey during Spring 2005 semester. The experimental group received instruction with analogy-enhanced model. The control group received instruction with traditional method. The matching-only pre-test- post-test control group design was used in the study. The fo...
The effects of physical manipulative with or without self-metacognitive questioning on sixth grade students' knowledge acquisition in polygons
Erdoğan, Beril; Ubuz, Behiye; Department of Secondary Science and Mathematics Education (2007)
This study compared the effect of the use of physical manipulative with self-metacognitive questioning versus manipulative without self-metacognitive questioning on the knowledge acquisition in polygons. Participants were 220 sixth grade students. A pretest, treatment and posttest two-group design was used. There were two treatment groups: manipulative with self-metacognitive questioning (MAN+META) and manipulative without self-metacognitive questioning (MAN) Three distinct knowledge tests were designed by ...
The Comparative Effects of Prediction/Discussion-Based Learning Cycle, Conceptual Change Text, and Traditional Instructions on Student Understanding of Genetics
Yilmaz, Diba; Öztekin, Ceren; Sungur, Semra (Informa UK Limited, 2011-01-01)
The present study examined the comparative effects of a prediction/discussion-based learning cycle, conceptual change text (CCT), and traditional instructions on students' understanding of genetics concepts. A quasi-experimental research design of the pre-test-post-test non-equivalent control group was adopted. The three intact classes, taught by the same science teacher, were randomly assigned as prediction/discussion-based learning cycle class (N = 30), CCT class (N = 25), and traditional class (N = 26). ...
