Stiffness Evaluation

The assessment of soft tissue stiffness is important to evaluate many neuromusculoskeletal conditions. Several tools have been proposed for the assessment of stiffness, but ultrasonography appears to be most practical. The reflection of ultrasound waves as it travels through tissue enables assessment of tissue echogenicity, which is influenced by the characteristics of the sound wave as well as the characteristics of the tissue through which it passes, such as the amount of fat and fibrous tissue. However, tissue stiffness is not directly proportional to its echogenicity. Hence evaluation of echogenicity, as a stand-alone technique, is inadequate to describe its mechanical properties. The aim of this manuscript is to present a method of combining echogenicity evaluation by ultrasound and stiffness evaluation by palpation to better describe the mechanical properties of muscle using a stiffness-echogenicity matrix.

Literacy Performance

We investigated whether 9-year-olds experience math and/or literacy worries and, if they do, whether it is related to problem-solving abilities. Fifty-eight children judged the correctness of math, literacy, and mental rotation problems that differed in difficulty and rated their worry level about the correctness of judgments. Nonverbal IQ, general math, and literacy abilities were also assessed. Results showed children's worry ratings varied as a function of task and problem difficulty. Latent class analyses of math and literacy worry ratings revealed high-, moderate- and low-worry subgroups in both domains. The high-worry math subgroup exhibited poorer math performance than the other math subgroups, demonstrating a link between math worry and math performance. No relationship was found between worry literacy subgroups and literacy performance. Moreover, no relationship was found between teachers’ rating of children's academic and general worry and children’s own worry ratings. The relevance of the findings for understanding math and literacy worry is discussed.

This study aims to produce teaching materials to improve problem-solving skills that are feasible to use as a class XII physics learning media on sound wave material. In addition, it is also to find out the response of students to teaching materials developed in terms of meeting the standards of usability and quality. This research is R & D research with design according to Borg including: needs analysis, product planning and development, product development, product evaluation, and final products. The instructional materials developed have been implemented in 63 students of class XII SMAN 5 Semarang. Data collection is done by giving a validation sheet to the senior teacher. Data on students 'problem solving abilities were obtained from the results of the pretest and posttest while the students' performance was seen from the observation of practical activities in the laboratory. Students are also given a questionnaire to provide input on the teaching materials that have been developed. The results of the study indicate that the product of development is declared feasible based on expert judgment. Implementation of teaching materials in physics learning in sound wave material is able to improve problem solving skills and student performance.

This study was conducted to derive implications on how educational activities should be organized and operated for improving creative competency in online class situations by analyzing how it has changed in classes before and after COVID-19. These classes were taken by science and engineering students who took the ‘Creative Thinking and Problem Solving’ subject operated by N University. In order to achieve the goals of this study, a pre-post test related to creative competency was administered at the beginning and end of the semester to 92 students who took the face-to-face class in the second semester of 2019, and to 120 students who took the on-line class in the second semester of 2020. The research results are as follows: Creative competency was significantly improved in the face-to-face class, but not in the online class. Looking at each sub-competency of creative competency, both the challenge spirit and problem solving ability were significantly improved in the face-to-face class. Moreover, the student’s challenge spirit ability was significantly improved in the online class, but their problem solving ability was not significantly improved. These results were similar regardless of whether the instructor changed, or if the students’ grades changed. Also, the students’ gender had no bearing on these results either. Based on these research results, as well as on our educational goals and the content of the classes, the project activities involved in the ‘Creative Thinking and Problem Solving’ subject can be used in online classes in their current form. But this study suggested that strategies for improving students' problem-solving abilities need to be supplemented. Specifically, instructors should increase communication opportunities through the parallel use of the real-time remote video system, and should guide their students to become faithful to the team-based project activities through the sub-session function of the real-time remote video system. To this end, the university may consider changing two credits of two hours into two credits of three hours, or three credits of three hours. Universities also need to operate this subject in connection with extra-activities. It is also necessary for instructors to provide a support environment where students can freely meet using the real-time remote video system, and can engage in solving problems through their own initiative.

Speech Model

The paper explores the processes by which children use private speech to regulate their behaviors. The first part of the paper explores the ontological development of self-regulating private speech. The theories of Vygotsky and Luria are used to explain this development. The second part of the paper applies these theories to pedagogical settings. The process by which children are exposed to dialogue strategies that help them solve problems is outlined. The strategy has children posing and answering four questions: What is the problem? How will I solve it? Am I using the plan? How did it work? It is argued that this model helps children systematically mediate their problem solving processes.
