In the study described here, teaching resources have been developed to provide students with explicit opportunities to link invariant properties across a range of different solution strategies, and make comparative judgments about the same solutions. After tackling an unstructured problem, students complete, compare and critique pre-designed student responses to the same problem. The framework used to analyze the data focuses on the types of links students may make between responses. The findings indicate students made varied links when completing them. The outcome of these links appeared to be influenced by how students perceived the representation being completed. Students made further assorted links that focused on invariant properties and the comparative validity of the completed responses.

When teachers give a problem like “Find 3/4 of 60,” they can anticipate the ways in which students will respond. It is easy to tell whether the student knows how to do the problem and whether she or he got the right answer. The mistakes that students might make on this problem are also predictable. Other problems found in traditional middle school curricula might produce more variety in solution strategies, but usually few surprises greet the experienced teacher. Few judgments need to be made, because the strategy is either appropriate or not; and barring computational errors, the answer is either right or wrong. This familiarity with the mathematics, the problems, and potential student responses produces a desirable level of comfort for teachers, even for those who are sometimes uncertain about their own mathematical skill and understanding. It leaves them free to focus on preparing students for the next skill to be learned and assisting those students who need extra help to become proficient. What happens when the curriculum, some of the mathematics, the problems, and the solution strategies all seem new and unpredictable? What does this situation mean for the teacher and for the students?

Purpose From the Audiology Education Summit held in 2017, several working groups were formed to explore ideas about improving the quality and consistency in graduate education in audiology and externship training. The results are described here from one of the working groups formed to examine postgraduate specialization fellowships. Method Over the course of a year, the committee designed and implemented two surveys: one directed toward faculty and one toward students. The rationale for the survey and the results are presented. Comparisons between faculty and student responses are made for similar questions. Results Overall, the results demonstrate that the majority of both students and faculty believe that postgraduation specialization fellowships are needed for either 1 year or a flexible length. There was a consensus of opinion that the fellowship should be paid, as these would be designed for licensed audiologists. Most believed that the fellowships should be “governed by a professional organization (e.g., American Speech-Language-Hearing Association, American Academy of Audiology, American Doctors of Audiology, etc.),” or less so, a “separate body for this specific purpose.” Potential topics for specialization identified were the following: tinnitus, vestibular, cochlear implants, pediatrics, and intraoperative monitoring. The highest priority attributes for a specialization site were “abundant access to patient populations,” “staff of clinical experts,” and “active research.” The weight put toward these attributes differed between faculty and students with faculty prioritizing “university/academic centers,” and “access to academic coursework in the fellowship area.” The faculty rated “caseload diversity,” “minimum hours,” “research,” and “academic affiliation” as requirements for a fellowship site, with less weight for “coursework” and “other.” Finally, the students valued “improved personal ability to provide exceptional patient care,” “the potential for increased job opportunities,” and the “potential for a higher salary” as benefits most important to them, with lower ratings for “recognition as a subject matter expert” or “potential pathway to Ph.D. program.” Conclusions As a result of the survey, further exploration of a postgraduate specialization fellowship is warranted, especially to determine funding opportunities to offset cost for the sites and to ensure that fellows are paid adequately.

The solution strategies of preschool children solving mental-rotation tasks were analyzed in two studies. In the first study n = 111 preschool children had to demonstrate their solution strategy in the Picture Rotation Test (PRT) items by thinking aloud; seven different strategies were identified. In the second study these strategies were confirmed by latent class analysis (LCA) with the PRT data of n = 565 preschool children. In addition, a close relationship was found between the solution strategy and children’s age. Results point to a stage model for the development of mental-rotation ability as measured by the PRT, going from inappropriate strategies like guessing or comparing details, to semiappropriate approaches like choosing the stimulus with the smallest angle discrepancy, to a holistic or analytic strategy. A latent transition analysis (LTA) revealed that the ability to mentally rotate objects can be influenced by training in the preschool age.

IPA Integrated is a place for students to study themselves and the surrounding environment applied in daily life. Integrated IPA Learning provides a direct experience to students through the use and development of scientific skills and attitudes. The importance of integrated IPA requires to pack learning well, integrated IPA integration with the preparation of modules combined with learning strategy can maximize the learning process in school. In SMP 209 Jakarta, the value of the integrated IPA is obtained from 34 students there are 10 students completed and 24 students are not complete because they get the value below the KKM of 68. This research is a development study with the development model of ADDIE (Analysis, Design, Development, Implementation, and Evaluation). The use of KPS-based integrated IPA modules (Science Process sSkills) on the theme of rainbow phenomenon obtained by media expert validation results with an average score of 84.38%, average material expert 82.18%, average linguist 75.37%. So the average of all aspects obtained by 80.55% is worth using and tested to students. The results of the teacher response obtained 88.69% value with excellent criteria. Student responses on a small scale acquired an average score of 85.19% with highly agreed criteria and on the large-scale student response gained a yield of 86.44% with very agreed criteria. So the module can be concluded receiving a good response by the teacher and students.

The problem of this research is motivated by the lack of students' ability in learning to write descriptions. Therefore the purpose of this research is to produce a syllabus for writing a description based on a valid, practical and effective media picture and picture. The model used in this study is the ADDIE model. The subjects in this study were students and teachers of SDN 01 Simabur. Validity data was taken from the learning syllabus validation sheet. Practicality data can be seen from the observation sheet of the implementation of the lesson plan, as well as the questionnaire of teacher and student opinions. The effectiveness data is seen from the results of students' writing learning. The results of the validity test by experts and practitioners are categorized as very valid namely 90% and 87%. The practicality of the syllabus is categorized as very practical, evidenced by observing the implementation of the RPP with a percentage of 89%, and supported by teacher and student responses of 90% and 91%. Finally, the effectiveness felt by students in writing descriptions is categorized to be very effective, which can improve students' ability to write descriptions. In short, that the development of syllabus writing description based on picture and picture media in grade IV elementary school can be declared valid, practical, and effective.

Background: This research was birthed in 2017 during a trip to Lusaka, Zambia, with the purpose of offering fourth-year, medical students attending the University of Zambia, School of Medicine, lectures on psychology topics as part of their clinical studies.  Students were also offered brief therapy sessions where they could process thoughts and feelings causing them internal struggles.  The subject of offering counseling on a regular basis was randomly discussed with the students.  From these discussions the need for this research became evident, with the intent of becoming the launching pad to brainstorm the most effective ways of developing a plan to offer counseling services for all medical students attending the University of Zambia School of Medicine. Methods: An-experimental research design, consisting of completion of a 12-item questionnaire administered by paper and pen. The inclusion criteria were the fourth year, medical students attending the University of Zambia, School of Medicine. Results:  The student responses revealed that most of them had little to no experience with counseling services, but a strong desire for them. Discussion: The goal of this study was to simply establish a need for an on-campus counseling service, the need of which has been established by the very students who would benefit.  With the acceptance of this need, the future plan is to explore the different ways in which this need can be fulfilled with minimal costs to the Medical School Program. Conclusion:  This study is the first step towards identifying the needs of the medical students and sets the ground-work for further research into the specific areas of need and mental health challenges.  More specificity in the area of demographics of students will produce a more comprehensive picture of the areas of concentration for the therapists offering services.

Pembuktian dalam matematika adalah suatu aktivitas yang penting, tetapi aktivitas ini tergolong sulit bagi mahasiswa calon guru matematika. Masalah ini salah satunya dipengaruhi oleh kepercayaan-diri. Tujuan penelitian ini adalah untuk menganalisis karakteristik pencapaian kemampuan pembuktian matematis dan kepercayaan-diri mahasiswa melalui metode Moore. Penelitian ini menggunakan metode campuran bertahap yaitu tahap kuantitatif dan tahap kualitatif. Pada tahap kuantitatif disimpulkan bahwa kemampuan pembuktian pada kelas yang menggunakan metode Moore lebih baik daripada kelas yang menggunakan model pembelajaran langsung. Metode Moore dapat mengungkap proses perkembangan capaian pembelajaran mahasiswa dalam pembuktian, sehingga dosen dapat memberikan umpan balik untuk mengembangkannya. Pada tahap kualitatif, dihasilkan karakteristik kemampuan pembuktian beberapa mahasiswa. Karakteristik ini ditinjau berdasarkan respon mahasiswa terhadap masalah pembuktian. Pada pembelajaran dengan metode Moore, mahasiswa tidak diperbolehkan membuka bahan ajar, sehingga dosen harus mengikuti alur berpikir mahasiswa dan mengarahkan proses berpikirnya. Sebagai implikasi, metode Moore baik digunakan dengan catatan mahasiswa harus belajar terlebih dahulu sebelum pembelajaran di kelas.Proving in mathematics is an important activity, but this activity is classified as difficult for prospective mathematics teacher students. This problem is influenced by self-confidence. The purpose of this study was to analyze the characteristics of achievement of students' mathematical proving ability and self-confidence  through the Moore method. This study uses a phased mixed method, namely quantitative and qualitative stages. In the quantitative stage, it was produced: "Based on the overall and PAM categories, the ability to prove the class using the Moore method is better than the class that uses the direct learning model". Moore's method can reveal the process of developing student learning outcomes in proof, so that lecturers can provide feedback to develop it. In the qualitative stage, the characteristics of the ability of several students are produced. these characteristics are reviewed based on student responses to the problem of proof. In the Moore method of learning, students are not allowed to open teaching materials, so the lecturer must follow the flow of student thinking and direct the thinking process. As an implication of the results of this study, the Moore method is well used with the notes that students must study before learning in class.
