In this study, we discussed the participating teachers‟ implementation and understanding of science, technology, engineering and mathematics (STEM) project based learning (PBL). A research team at a STEM center systematically offered professional development activities to 92 teachers in an urban school district in the southern U.S. To investigate the teachers‟ implementation and understanding of the STEM PBL pedagogy, we conducted a collective case study with five teachers. Study data included i

Abstract The present study aims to investigate the effects of smartphone use by college students on their perceived academic performance. Using five hypotheses derived from the literature related to smartphone use, the initial model was set up for path analysis to reveal the relationships among variables regarding college students' smartphone use in the academic setting. Moreover, multiple group analyses were additionally conducted to verify whether students exhibited different relationships in

The integration of project-based learning in Science, Technology, Engineering, and Mathematics activities has received much attention because of its potential in engaging students with real–world problem solving. This study was designed to examine the effectiveness of Science, Technology, Engineering, and Mathematics project-based learning lessons on students’ achievement in algebra, geometry, probability and problem solving. The achievements of two groups of students who participated in the stu

The trend of avoiding science, technology, engineering, and mathematics (STEM) majors has persisted resulting in a lack of professionals in STEM fields. Further, the current STEM education system in Korea does not meet domestic demands for STEM labor. To discover an educational approach encouraging students to choose STEM majors at the post-secondary level, the current study employed a survey instrument investigating students’ attitudes toward STEM project based learning (PBL), and examined the

The purpose of this study was to explore how a science, technology, engineering, and mathematics (STEM) project with mathematical modeling influenced student competencies regarding sustainability in a university classroom. We used mixed methods with a convergent parallel design. Forty-two students participated in a STEM project during six consecutive sessions of an algebra class. Before and after the STEM project, the students completed surveys about their perceptions of the mathematical modelin

This study examined the effects of shadow education on high school students’ creative thinking and academic achievement in mathematics. Data from the Seoul Education Longitudinal Study were used for the analyses, including descriptive statistics, path analyses, and multiple group analyses. The results reveal that shadow education negatively influenced students’ creative thinking in the long term, but positively affected academic achievement in mathematics in the short term. Furthermore, students

The purpose of this study was to examine student attitudes toward science, technology, engineering, and mathematics (STEM) project-based learning (PBL). To guarantee the impact of STEM PBL on academic achievement, it is important to understand student attitudes toward STEM PBL. The initial survey consisted of 51 items, which were created by the authors and adapted/adjusted from previous studies. Exploratory factor analysis and confirmatory factor analysis were employed to examine the psychometri

In this rapidly changing world, universities have an increased responsibility to prepare professionals for a sustainable future, and teacher education is not an exception to this. In this study, we observed a group of preservice teachers engaging in a statistical investigation project. Specifically, we examined their degree of statistical knowledge; how effective the project was in enhancing their statistical knowledge and thinking; and how they participated in the project to make and share data

Bu çalışmanın amacı problem çözme becerisinin bileşenleri (dört adet yöntemsel bileşen ve modelleme yeterliliği) arasındaki ilişkilerin ve öğretim stratejilerinin (işbirlikçi öğrenme ve problem kurma) öğrencilerin matematiksel modelleme yeterliliği üzerindeki etkisini araştırmaktır. Kore’de 1224 öğrencinin katılımıyla öğrencilerin matematiksel problem çözme yeterliliğine ilişkin 40 maddeden oluşan bir anket gerçekleştirilmiş olup ankete verilen yanıtlar nicel yöntemler kullanılarak analiz edilmi

교사의 교육철학은 학교 현장의 교육에 있어서 중요한 역할을 함에도 불구하고, 현 교사 양성 교육과정에서는 교사의 교육철학이 소홀하게 다뤄지고 있다. 교직과목에서 뿐만 아니라 교과교육학 과목에서도 교사의 교육철학이 비중 있게 다뤄질 수 있도록 교육과정을 개선하기 위해서는 우선 예비 교사들의 교육적 신념에 대해 살펴보는 것이 필수적이다. 따라서 본 연구는 수학 예비 교사의 교육 철학과 그것의 하위 영역을 살펴본 후 그 영역들 간의 관계에 대해 논하고자 한다. 수학 교사의 교육철학과 관련한 기존의 연구들은 주로 ‘교사의 신념’에 대한 것이었으며 연구 방법으로는 설문이나 질문지를 통한 연역적 접근이 대부분이었다. 이 연구들은 공통적으로 수학 교사의 신념을 ‘수학 본질에 대한 신념’, ‘수학 교수 방법에 대한 신념’, 그리고 ‘수학 학습 방법에 대한 신념’의 세 가지 영역으로 구분하였다. 이렇듯 교사 신념에 대한 세 가지 영역의 구분이 점차 고착화되었고 그 외의 다른 영역이 존재하는가에 대한

문제해결력은 수학 교육의 핵심역량 중 하나이다. 학습자의 문제해결력을 함양시키기 위한 한 가지 방법으로 프로젝트기법 혹은 프로젝트기반학습의 전략이 개발되고 적용되어져 왔다. 프로젝트를 활용한 교수·학습 방법은 학습자로 하여금 비정형의 문제를 이해하고, 해결방법을 찾아내고, 반성하는 등의 과정을 경험하게 함으로써 결과적으로 문제해결력을 함양시키는데 효과적일 수 있다. 본 연구는 최근 10여 년간의 학술 논문에 소개되었던 프로젝트 활용의 성격과 역사를 분석함으로써 앞으로의 프로젝트기반학습을 현장에 적용하는데 고려해야 할 점을 도출하였다.
