Sari, Puspita; Hajizah, Mimi Nur; Purwanto, Swida – Journal on Mathematics Education, 2020
The number line and the neutralization model have been used very extensively in teaching integer additions and subtractions for decades. Despite their advantages, issues concerning subtractions on these models are still debatable. Therefore, the neutralization on an empty number line (NNL) model is proposed in this research to help students better…

Inel, Yusuf; Urhan, Emrah – International Journal of Contemporary Educational Research, 2020
This study aims to find out the effect of activities and practices on concept education to help carry out activities to teach these concepts more effectively and permanently, and determine student preconceptions about the concepts related to the landforms in the 5th-grade social studies curriculum in the learning subdomain called "People,…

Pratt, Sarah S.; Lupton, Tina M.; Richardson, Kerri – Teaching Children Mathematics, 2015
As teachers seek activities to assist students in understanding division as more than just the algorithm, they find many examples of division as fair sharing. However, teachers have few activities to engage students in a quotative (measurement) model of division. Efraim Fischbein and his colleagues (1985) defined two types of whole-number…

Paik, Seoung-Hey – Chemistry Education Research and Practice, 2015
The purpose of this study was to explore how examples used in teaching may influence elementary school students' conceptions of evaporation and boiling. To this end, the examples traditionally used to explain evaporation and boiling in Korean 4th grade science textbooks were analyzed. The functions of these published examples were explanation…

Durkin, Kelley; Rittle-Johnson, Bethany – Learning and Instruction, 2012
Comparing common mathematical errors to correct examples may facilitate learning, even for students with limited prior domain knowledge. We examined whether studying incorrect and correct examples was more effective than studying two correct examples across prior knowledge levels. Fourth- and fifth-grade students (N = 74) learned about decimal…

Hauck, Nancy – ProQuest LLC, 2012
The purpose of this study was to determine the extent to which sustained teacher professional development in science education affects the classroom instruction of elementary school teachers in third through sixth grade over a 3-year period. The teachers in the study were all elementary endorsed and prepared to be generalists in the content areas.…

Yang, Chih-Chiang; Hung, Jeng-Fung – Online Submission, 2012
The roles of conceptual change and model building in science education are very important and have a profound and wide effect on teaching science. This study examines the change in children's position concepts after instruction, based on different conceptual change theories. Three classes were chosen and divided into three groups, including a…

Hochbein, Craig – Leadership and Policy in Schools, 2012
The purpose of this study is to determine the validity of common assumptions about the rate at which school decline manifests. From a population of 981 elementary schools in the state of Virginia, the author uses three operational definitions of school decline to identify samples of declining schools: Absolute (n = 217), Relational (n = 510), and…

Cepni, Salih; Keles, Esra – International Journal of Science and Mathematics Education, 2006
In this study, the Turkish students' understanding level of electric circuits consisting of two bulbs and one battery was investigated by using open-ended questions. Two-hundred fifty students, whose ages range from 11 to 22, were chosen from five different groups at primary, secondary and university levels in Trabzon in Turkey. In analyzing…

Sharp, Janet; Hoiberg, Karen; Chumbley, Scott – Science and Children, 2003
This standard lesson on identifying salt and sugar crystals expands into an opportunity for students to develop their observation, questioning, and modeling skills. Although sugar and salt may look similar, students discovered that they looked very different under a magnifying glass and behaved differently when dissolved in water. In addition,…
