This article presents a culturally situated and socially relevant lesson for intentionally teaching secondary students the fundamental engineering concepts related to Problem Framing and Project Management. This lesson includes: (1) class discussions to engage students in a socially relevant problem (food waste and sustainability) within a…

Ratio-proportion is one of the topics that middle school students have difficulty in comprehending. This study aims to determine the learning difficulties that seventh-grade students face while learning about ratio-proportion. Three commonly used strategies to solve ratio-proportion problems are buildup, unit ratio and cross-multiplication. The…

The purpose of this research was to explore students' problem-solving skills through inquiry-based learning with PhET simulation, focussed on direct current electricity matter. The research used a mixed method approach with an embedded experimental model with 34 prospective physics teacher at the State University of Jambi, Indonesia. The data was…

This article examines the work of 30 in-service teachers engaged with modelling activities during a course within an Ecuadorian master's degree program in mathematics teaching. These teachers experienced a sequence of activities designed to explore imaginative aspects of mathematical modelling and problem solving, inviting perspectives from life…

This article explores 6th-grade students' modelling with data in generating models for selecting an Australian swimming team for the (then) forthcoming 2016 Olympics, using data on swimmers' times at various previous events. We propose a modelling framework comprising four components: working in shared problem spaces between mathematics and…

Posing modelling problems in class is supposed to increase students' motivation. As motivation is assumed to emerge from task value and self-efficacy expectations, the present study considered both constructs with the aims to examine (1) whether students have different values and self-efficacy expectations concerning modelling problems versus…

Mathematical modeling, a key strand in mathematics, engages students in rich, authentic, exciting, and culturally relevant problems and connects abstract mathematics to the surrounding world. In this, article, the authors describe a modeling activity that can be used when teaching linear equations. Modeling problems, in general, are typically high…

Numerous studies have shown that mathematical knowledge is situational, meaning that students' abilities to transfer and apply skills depends on the conditions in which they were learned (Barab 1999; Boaler 2002, 2016). Given that the real world seldom presents problems that are confined to a single discipline (Barab 1999), it is imperative that…

This paper analyses job satisfaction and differences in factors affecting it among workers with an intellectual disability and mental illness (MI) depending on their work regime [special employment regime (SER) or occupational service (OS)]. To do so, answers were analysed from 874 participants on a Job Satisfaction Scale used in sheltered…

This study aimed to determine STEM practices assisted by argumentation-based learning, the attitudes and the opinions of the students towards STEM, their perception of problem-solving skills and the argumentation qualifications. In the research, the mixed design has been implemented. The quasi-experimental design with pre-test and post-test…

This research was based on the concern that students didn't see the need for the acquisition of science skills and knowledge perceived as important in relation to different society issues and the world of work. The aim was to determine gymnasium students perceived self-efficacy towards working life skills as well as science curriculum,…

This case study describes how our research team conducted the qualitative think-aloud approach (or cognitive pretesting) to obtaining cognitive validity evidence for a biology inference-making and reasoning measure for undergraduate students. The main goal of our work was to gather high-quality student think-aloud data of reasoning while they were…

This mixed methods study explores secondary students' math identities. The primary purpose of this dissertation is to examine the relationships among students' math identities, their perceived problem solving practices, and their perceived self-regulated learning strategies. This study holds implications for teachers, school administrators,…

The strategy choice model (SCM) is a highly influential theory of human problem-solving. One strength of this theory is the allowance for both item and person variance to contribute to problem-solving outcomes, but this central tenet of the model has not been empirically tested. Explanatory item response theory (EIRT) provides an ideal approach to…

This study examined how or why teachers' perspectives on the importance of infusing self-determination, including problem-solving, goal-setting, and choice-making, might help determine the benefits and use of self-determination as an instructional intervention. The self-determination theory and the causal agency theory were the theoretical…
