ASSISTments is a free online learning tool for improving students' mathematics achievement by providing immediate feedback and hints to students, detailed information on how students performed to teachers, and instructional suggestions for teachers to use. Researchers at the Friday Institute for Educational Innovation conducted an intrinsic,…

Much of the literature surrounding the effectiveness of intelligent tutoring systems has focused on the type of feedback students receive. Current research suggests that the timing of feedback also plays a role in improved learning. Some researchers have shown that delaying feedback might lead to a "desirable difficulty", where students'…

Considered by many as a source of valuable data and a potential to improve mathematics education, a significant amount of studies have been conducted on The National Assessment Program -- Literacy and Numeracy (NAPLAN) test results. This study is a systematic literature review of 86 peer-reviewed journal articles published between 2008 and 2017 to…

Critical thinking and STEM career perception are important in 21th century and STEM education is necessary to promote middle school students' critical thinking skills and STEM perception. In this research we aim to research the effects of engineering design-based STEM education on the middle school students' critical thinking skills and STEM…

Environmental education is defined as raising self-sacrificing people with an awareness of all kinds of problems and solutions to create a more sustainable environment. Environmental literacy is essential in environmental education. The concept of environmental literacy means having a good education in the field of the environment and a high level…

This work aims at studying the anxiety and motivation levels of secondary school students towards science course depending on gender, class levels, and their parents' level of education. In addition, it was aimed to examine the relationship between students' anxiety, motivation, and academic achievement towards science course. The study relies on…

This study aims to investigate the effect of history-of-mathematics activities on the development of mental computation of middle-grade students and to determine the students' views on the history of mathematics. This study was carried out as an action research project. The participants of the study consisted of 19 seventh-grade students studying…

The aim of this study is to examine the effect of SCM-based self-regulation writing instruction on the expository writing and self-regulation skills of middle school 7th grade students. In the research, explanatory sequential mixed method, in which qualitative and quantitative research designs are used together, was used. In the quantitative…

The purpose of this study is to examine how teachers' PCK is expressed in science teaching practice, both from a teacher's and a student's perspective. It is a qualitative study of three teachers' physics classroom lectures in grades 7 and 8. International research has highlighted the impact of teachers on students' achievement in general and in…

We constructed and calibrated an instrument targeting conceptual and procedural fraction knowledge. We used this instrument in a quantitative study with 126 secondary students (7th and 9th graders), testing the hypothesis that there are individual differences in the way students combine the two types of knowledge. Cluster analysis revealed four…

The aim of this study is to examine how the nature of science dimensions are represented in the secondary school 5th, 6th, 7th, and 8th grade science textbooks of the last twenty years. It is also within the scope of the research to investigate how these dimensions in the textbooks changed during the twenty years. The document analysis method was…

Although understandings of scientific inquiry (as opposed to conducting inquiry) are included in science education reform documents around the world, little is known about what students have learned about inquiry during their elementary school years. This is partially due to the lack of any assessment instrument to measure understandings about…

Purpose: In 2017 and 2018, engineering applications and design process were given weight to with the updates carried out in the Physical Sciences Lesson Curriculum in Turkey. For the STEM education which is at the center of this update to reach its target, it is highly important that students accurately learn what engineers do, what their work…

The aim of this study was to examine the loneliness levels of students at the middle school level and their digital game addictions in terms of various variables. The study group consisted of 404 volunteer students in 5th-8th grade in Kutahya, Turkey. As data collection tools, "Digital Game Addiction Scale", developed by Lemmens et al.…

International research suggests that early mathematical competences predicts later mathematical outcomes. In this paper, we build on our previous study of young children's mathematical competencies (MacDonald & Carmichael, 2015) to explore the relationship between mathematical competencies at 4-5 years, as measured by teacher ratings, and…
