The aim of this study was to investigate second-grade elementary school students' performance related to their counting skills, place value understanding, and addition operation in natural numbers. A total of 205 second-grade elementary school students from Turkey participated in this study. The data were collected through a 'Personal Information…

Introducing the distributivity property of multiplication over addition is a well-known challenge in mathematics education, especially in primary school. As a contribution, this paper presents the results of a cycle of design research that focuses on the design, implementation and evaluation of a modelling activity in which 2nd-grade students are…

The aim of this study was to improve the 2nd- and 3rd-graders' conceptual subitizing skills by using in-class activities, and to examine whether the practice affects the students' basic number processing skills, calculation performance and overall mathematics achievement in the long run. The training was carried out for eight weeks (640 min in…

A critical challenge for elementary mathematics teachers is meeting the learning needs of all students, especially when there is variability in students' number knowledge. Because young students' number system knowledge (NSK) contributes to future success in mathematics, NSK activities must be designed to engage all students, particularly students…

The purpose of this mixed methods triangulation convergence study (Creswell & Clark, 2017) was to identify the differences between expressions of understanding through writing versus video reflection in a second-grade science classroom. Specifically, we analyzed the reflective piece of the design thinking of the engineering and design process…

This paper reports the professional journey of an English as a foreign language (EFL) teacher from teaching older learners to teaching younger children at a primary school, and the impact of mentoring on the teacher in facilitating the transitioning process. The participant is a Turkish native-speaker male English teacher with 23 years of teaching…

This study investigates the impact of an elementary engineering education teacher professional development program on student learning. The results show a significant increase in students' knowledge in science from pre- to post-test as well as in engineering design from grade two to grade four. Further, the study uses multilevel modeling to…

Many students around the world are exposed to a rote teaching style in mathematics that emphasizes memorization of procedures. Students are frequently presented with standard types of equations in their textbooks, in which the equal sign is immediately preceding the answer (a + b = c). This exposure can lead to many misconceptions, such as…

Soroban abacus training is called as mental arithmetic training in our country. It is known for mental arithmetic to increase the ability of four mode operations. Besides this, how is the situation for the students which are having Soroban abacus training in the terms of problem solving abilities, creativity, development of concepts, attraction…
