Multiscale modeling is a key tool for developing effective techniques to describethese phenomena, which may otherwise be computationally intractable. Specifically, assuming scale-separation in mod-els allows us to examine the interplay between processes active on vastly different length and time scales, defining, forexample, phenomena on macroscales and microscales [13, 53]. In most practically relevant cases, the microscalesare active in the sense that they are hosting localized phase transitions described mathematically by moving interfaceswith a priori known or unknown velocities. The case of known interface velocities is both mathematically and computa-tionally well-understood (cf. e.g., [10]), while the case of unknown interface velocities is still a matter of concern, compare[11, 55] for some very recent asymptotic analysis results concerning closely related reaction-diffusion scenarioswhich arise in the context of reactive transport in porous media.Here, we consider a flow process that takes place on two distinct physical scales. In the simplest setting, we canidentify a macroscopic scale where a model governs the behavior of a (macroscopic) fluid in which averages over theThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided theoriginal work is properly cited.© 2024 The Authors.

Global Education Review, 1 ( 4 ) . 76 - 95. Metacognition, M otivation, and E motions: Contribution of S elf - R egulated L earning to S olving M athematical P roblems Meirav Tzohar - Rozen Levinsky College of Education Bracha Kramarski Bar - Ilan University Abstract Mathematical problem solving is one of t he most valuable aspects of mathematics education. It is also the most difficult for elementary - school students (Verschaffel, Greer, & De Corte, 2000). Students experience cognitive and metacognitive difficulties in this area and develop negative emotions and poor motivation, which hamper their efforts ( 4T Kramarski, 3T 4T 3T 4T Weiss, & Kololshi - Minsker 4T, 2010). The ages of nine through 11 seem to be the most critical for developing attitudes and emotional reactions towards mathematics (Artino, 2009). These metacognitive and motivational - emotional reactions are fundamental aspects of self - regulated learning (SRL), a non - innate process which requires systematic, explicit student training (Pintrich, 2000, Zimmerman, 2000). Most self - regulation studies about problem solving tend to focus on metacognition, few have explored the motivational - emotional component. This study developed, examined, and compared two SRL interventions dealing with two components of self - regulation: metacognitive regulation (MC) and motivational - emotio nal regulation (ME). The study conducted a two - group intervention to examine the possible effects on the self - regulation aspect of student problem - solving ability of increasing one group’s metacognitive awareness, while leaving the motivational - emotional c omponent alone, and of increasing the motivational - emotional awareness of the other group, while leaving metacognitive awareness alone. It also examined the contribution of these components to students’ problem solving and self - regulation. Participants we re 118 fifth - grade students randomly assigned to two groups. The groups completed self - regulation questionnaires before and after intervention to examine metacognition, motivation, and emotion. Students also solved two forms of a 11T rithmetic series problems: verbal and numeric. 11T After intervention, a novel transfer problem was also examined. The intervention consisted of 10 hours over five weeks. Following intervention, the groups exhibited similar improvements in all problems. The MC group performed best in me tacognitive self - regulation, and the ME group performed best in certain motivational - emotional aspects of self - regulation. Research implications are discussed.
