The Common Core Mathematics Standards have raised expectations for schools and students in the United States. These standards demand much deeper content knowledge from teachers of mathematics their students. Given increasingly diverse student population today’s classrooms shortage qualified special education teachers, computer-assisted instruction may provide supplementary support, conjunction with core instruction, meeting needs different learning profiles. purpose this study was to explore...
ABSTRACT The authors compared a conceptual model- based problem-solving (COMPS) approach with general heuristic instructional for teaching multiplication–division word-problem solving to elementary students learning problems (LP). results indicate that only the COMPS group significantly improved, from pretests posttests, their performance on criterion test (that involves equal groups and multiplicative compare problems) prealgebra model expression test. study suggest LP can be expected move...
Informed by a constructivist-based, student-adaptive pedagogical approach, this study explores the benefits of teacher–learner discourse moves for mathematics learning students with disabilities (LD). During constructivist teaching experiment nurturing multiplicative reasoning and problem solving five third-grade school-identified LD, we analyzed global trends detailed dynamics teacher–student interactions statistical analysis. We found that teacher’s to support each individual student’s...
Adaptive automation (AA) can improve performance while addressing the problems associated with a fully automated system. The best way to invoke AA is unclear, but two ways include critical events and operator's state. A hybrid model of invocation, dynamic operator overload (DMOO), that takes into account state was recently shown performance. DMOO initiates using attention allocation, informed by eye movements. We compared an inaccurate invocation system invoked based only on events. Fewer...
This research shows that employing critical thinking (problem-solving and scientific reasoning) skills when learning about climate change helped undergraduate biology students to understand the subject matter better. In this post hoc analysis of pre- post-test scores from a public Florida college, we identified significant results, with medium effect sizes, for treatment help undergraduates tie together concepts on in introductory classes. Age was determined not be factor.
Project-Based Instruction (PBI) is prevalent in science classrooms, which focuses on real-world tasks as a vehicle for student learning. PBI can be fitting instructional approach to enhance mathematics problem-solving. This case study explored two pre-service secondary teachers’ with problem-solving based their intended and enacted lessons. Data sources were the teacher (PST)’s lesson plans video-recorded classroom observations. Results from data analysis report that PSTs employed wide range...
Quantitative Reasoning (QR) is essential for today's students, yet most higher education institutions have not effectively addressed this issue. This study investigates students' quantitative reasoning in STEM and Non-STEM math pathways using a non-proprietary, NSF grant-funded instrument, the Literacy & Assessment (QLRA). Participants were students enrolled at least one college-level pathway course large public institution southeastern US. The results showed significant difference between...
Estimating the difficulty level of math word problems is an important task for many educational applications. Identification relevant and irrelevant sentences in step calculating levels such problems. This paper addresses a novel application text categorization to identify two types mathematical problems, namely sentences. A joint probabilistic classification model proposed estimate probability decisions all problem by utilizing correlation among along with between question sentence other...

The increased relevancy and importance of quantitative literacy (QL) have called for educational reform in undergraduate mathematics course offerings. However, lack clear guidelines has led to wide variability the content outcomes math courses meant address QL. Therefore, having an expert consensus regarding focusing on QL would advance initiative higher education. authors propose Delphi Method aid developing a framework based opinions. explain suggest result this process should yield...
기후변화는 현상 자체의 복잡성과 대응방안의 중요성을 고려할 때, 다양한 분야의 협력을 통한 통합적 접근이 필요한 분야이다. 본 연구에서는 기후변화 분야 학술연구에서의 협력 연구 구조와 연구에서 중심적인 역할을 하는 연구자의 특징을 알아보고자 하였다. 이를 위해, 2012년부터 2016년까지 발간된 학술 문헌 자료를 바탕으로 국내 연구자 중심의 공저자 네트워크 구조를 분석하고, 내에서 지식을 전달하는 매개 중개자들의 특성을 살펴보았다. 공동저자 네트워크는 하나의 큰 컴포넌트 외에는 대부분 분절된 컴포넌트로 구성되어 있었으며, 전반적인 연결수준이 높지 않은 것으로 나타났다. 높은 중심성 지수를 보이는 중개자 15명의 경력과 분야를 살펴본 결과, 경력에서는 뚜렷한 경향성을 보이지 않았지만 전체 연구자에 비해 다학제 연구의 비중이 것을 확인할 수 있었다. 연구는 주로 지구과학 및 환경과학 중심으로 공동연구가 이루어졌으나, 현상의 과학적 이해에서 나아가 산업의 기술혁신과 국제 사회의...
급속도로 진행되는 고령화는 출생성비 불균형완화와 더불어 우리사회가 "남초"(男超)에서 "여초"(女超)로 전환하는데 기여하였다. 남성에 비해 상대적으로 긴 수명을 가지고 있고, 제한된 사회참여의 기회로 인하여 경제적 독립이 어려울 수밖에 없는 여성노인들에게 건강은 노년의 삶의 질을 좌우하는 결정적인 요소로 작용한다. 이에 본 연구는 1995년에서 2016년까지 진행된 여성노인의 건강 및 신체활동에 대한 연구를 대상으로 메타분석을 통해 주요 주제와 연구 요인의 전반적인 흐름과 지형을 살펴보았다. 결과, 시기와 상관없이 건강과 있어서 가장 중심적인 역할을 한 것은 재활 신체활동과 신체관련 기능 나타났다. 아쉬운 부분은 직접적 요소라 할 수 있는 신체적 요소의 비중에 사회적, 심리적 비중이 낮은 것이었다. 연구의 주제인 신체활동은 1인 가구의 급속한 증가와 함께 여성의 수명으로 인해 향후 여성 독거노인의 문제와 직접적으로 연관되어 있다는 점에서 학문적 필요성 뿐 아니라 정책적 차원의...
