It is the intention of the current study to suggest a trajectory for the advancement of prospective mathematics teachers’ use of meta-cognitive skills in solving mathematics-based programming problems with Scratch. Scratch is a code-based program that can be utilized in teaching various disciplines, especially geometry and its rich range of subjects such as the topic of symmetry. The present study suggests that advancing prospective teachers’ meta-cognitive skills in the Scratch environment could be done through problem solving and negotiations. The present paper analyzed the implementation of the trajectory by two pedagogic supervisors who attempted, in the frame of one-year preparation (2018–2019), to educate 18 prospective teachers to use meta-cognitive skills in mathematics-based programming activities, where this attempt was based on problem solving and negotiation processes. Data were collected through videoing and recording the learning sessions of the prospective teachers and was analyzed using deductive and inductive constant comparison methods. The deductive analysis utilized theoretical models of meta-cognitive processes and negotiation processes. The research results indicated that the negotiation processes supported the development of the prospective teachers’ meta-cognitive processes in solving mathematics-based programming problems with Scratch.

Physical Manipulation

The rise of dynamic modeling and 3-D design technologies provides appealing opportunities for mathematics teachers to reconsider a host of pedagogical issues in mathematics education, ranging from motivation to application and from visualization to physical manipulation. This article reports on a classroom teaching experiment about cube spinning, integrating traditional tools, GeoGebra (www.geogebra.org), and 3-D design and printing technologies. It highlights the rich interplay between worthwhile mathematical tasks and the strategic use of diverse technologies in sustaining sense making and problem solving with a group of prospective teachers.

Object Problem

This paper presents a brief analysis of most known problem solving theoretical models realized using epistemological categories such as observer position, object of study, methods and procedures, and descriptive or explicative scope. The review showed linear and cyclical models, the need to recognize method's limitations to generalizing, the relevance of expliciting observer position, and a diffuse delimitation of the object problem solving as a cognitive process. An integrative and molar theoretical model of problem solving as a dependent variable is proposed whose variations go with critical cognitive processes (information processing, comprehension, reasoning, cognitive styles, and attitudes). Its molar feature refers to that it integrates basic and high order processes in a general cognitive activity; this proposal has to be extensively tested.

A sequel to the author’s article in the preceding issue on the origins, purpose, and planners of Los Angeles’s scenic Mulholland Drive, this article traces the phenomenal accomplishment of the 24-mile mountain road’s construction in one year and under budget. It details the supervision and problem-solving by construction engineer DeWitt L. Reaburn, the bureaucratic streamlining, the use of the latest 1920s road-building technology, and the efficient manpower logistics that made this possible.

The purpose – perfection of the techniques for controlling speed-strength capabilities and endurance of the rotator cuff muscles of biathletes during the period of sport skills perfection. Research methods and organization. The study involved 204 biathletes aged 15-17. We tested the speed- strength abilities and endurance of rotator cuff muscles with the Skierg Concept2 ski ergometer (USA). Research results. Significant changes in the endurance of rotator cuff muscles of biathletes occur in the age period from 15 to 16 years. The change in speed-strength abilities of female biathletes, in contrast to male biathletes, occurs against the background of an increase in the number of ski pole movements per minute. We processed the obtained data using the method of determining the boundaries of confidence intervals. Based on the data processed, we developed the standards for assessment of the speed-strength abilities and strength endurance of rotator cuff muscles of biathletes during the period of sport skills perfection with the Skierg Concept2 ski ergometer (USA). We tested applicability of the developed standards for speed-strength abilities and strength endurance of rotator cuff muscles in a one-year educational experiment. Conclusion. We proposed a methodology for testing speed-strength abilities and strength endurance of rotator cuff muscles with the Skierg Concept2 ski ergometer (USA) in the framework of our study. The developed stand- ards for assessing speed-strength abilities and strength endurance of rotator cuff muscles of biathletes during the period of sport skills perfection help to identify strong and weak points of fitness and to predict the possibility of achieving certain results by individual parameters.

Due to the COVID-19 restrictions, on-site Incident Commander (IC) practical training and examinations in Sweden were canceled as of March 2020. The graduation of one IC class was, however, conducted through Remote Virtual Simulation (RVS), the first such examination to our current knowledge. This paper presents the necessary enablers for setting up RVS and its influence on cognitive aspects of assessing practical competences. Data were gathered through observations, questionnaires, and interviews from students and instructors, using action-case research methodology. The results show the potential of RVS for supporting higher cognitive processes, such as recognition, comprehension, problem solving, decision making, and allowed students to demonstrate whether they had achieved the required learning objectives. Other reported benefits were the value of not gathering people (imposed by the pandemic), experiencing new, challenging incident scenarios, increased motivation for applying RVS based training both for students and instructors, and reduced traveling (corresponding to 15,400 km for a class). While further research is needed for defining how to integrate RVS in practical training and assessment for IC education and for increased generalizability, this research pinpoints current benefits and limitations, in relation to the cognitive aspects and in comparison, to previous examination formats.

Problem Solving Behavior

Organic chemistry education is one of the youngest research areas among all chemistry related research efforts, and its published scholarly work has become vibrant and diverse over the last 15 years. Research on problem-solving behavior, students' use of the arrow-pushing formalism, the investigation of students' conceptual knowledge and their cognitive skills have shaped our understanding of college students' understanding in organic chemistry classes. This review provides an overview of research efforts focusing on student's perspectives and summarizes the main results and pending questions that may guide subsequent research activities.
