AbstractThis article reports on a case study that aims to help students develop mechanistic reasoning through constructing a model based stop-motion animation of a physical phenomenon. Mechanistic reasoning is a valuable thinking strategy for students in trying to make sense of scientific phenomena. Ten ninth-grade students used stop-motion software to create an animation of projectile motion. Retrospective think-aloud interviews were conducted to investigate how the construction of a stop-motion animation induced the students’ mechanistic reasoning. Mechanistic reasoning did occur while the students engaged in creating the animation, in particular chunking and sequencing. Moreover, all students eventually exhibited mechanistic reasoning including abstract concepts, e.g., not directly observable agents. Students who reached the highest level of mechanistic reasoning, i.e., chaining, demonstrated deeper conceptual understanding of content.

English grammar is how words in the English language are translated into text. This includes the structure of words, phrases, clauses, and phrases, up to and including full-text structure. The main objective of the authors is to discover the difficulties of grammatical structures for students at the Department of Teacher Education. Shikarpur Shaikh Ayaz University. The students of B.Ed. undergraduate level of education department was selected as a data population. The fifty students were randomly selected from the education department. There is quantitative research underway. The researchers used a testing tool for a questionnaire. The student's collected data were analyzed by SPSS-Descriptive statistics.  Some of the challenges and problems are facing during the English Grammar lesson of B.Ed. students. The students have used the conditional verb and also the proper use of a phrasal verb that is one of the problems with students. The use of an article is also one of the fundamental problems for undergraduate students. Teachers should make it possible for students to practice these materials either through activity-based teaching or through the CLT method so that they can be more attentive to EFL learning and not focus on translation alone.

Conceptual understanding has been emphasized in the national curriculum and principles and standards across nations as it is the key in mathematical learning. However, mathematics instruction in classrooms often relies on rote memorization of mathematical rules and formulae without conceptual connections. This study considers the concreteness fading instruction strategy—starting with physical activities with manipulatives and gradually fading concreteness to access abstract concepts and representations—as a promising and sustainable instructional model for supporting students in accessing conceptual understanding in mathematics classrooms. The results from the case study support the validity of the concreteness fading framework in providing specific instructional strategies in each phase of concept development. This study implies the development of sustainable teacher education and professional development by providing specific instructional strategies for conceptual understanding.

ABSTRACTThe effect of inertial forces on the Structural Dynamics (SD) behaviour of Elastic Flapping Wings (EFWs) is investigated. In this regard, an analytical modal-based SD solution of EFW undergoing a prescribed rigid body motion is initially derived. The formulated initial-value problem is solved analytically to study the EFW structural responses, and sensitivity with respect to EFWs’ key parameters. As a case study, a rectangular wing undergoing a prescribed sinusoidal motion is simulated. The analytical solution is derived for the first time and helps towards a conceptual understanding of the overall EFW's SD behaviour and its analysis required in their designs. Specifically, the EFW transient and steady response in on-off servo condition is also attended.

PurposeThis paper draws on the archival records of the Victorian Education Department, literature produced by the governing authority of Tally Ho (the Central Mission), and newspaper reports produced in the mid-20th century about school and education at Tally Ho. This paper also draws on material from the Victorian Aborigines Welfare Board and the Northern Territory Department of Welfare, as well as two historical key government inquiries into the institutionalisation of children.Design/methodology/approachThis paper uses Tally Ho Boys’ Training Farm as a case study to examine the intersection of welfare systems, justice systems and schooling and education for Aboriginal children in institutions like Tally Ho in the mid-20th century. Further, it provides perspectives on how institutions such as Tally Ho were utilised by governments in Victoria and the Northern Territory to pursue different agendas – sometimes educational – particular to Aboriginal children. This paper also explores how histories can be reconstructed when archives are missing or silent about histories of Aboriginal childhood.FindingsThis paper demonstrates how governments used Tally Ho to control and govern the lives of Aboriginal children. By drawing together archives from a range of bodies and authorities who controlled legislation and policies, this paper contributes new understandings about the role of institutions in Victoria to the assimilation policies of Victoria and the Northern Territory in the mid-20th century.Originality/valueScholarship on the institutionalisation of children in the post-war era in Victoria, including the ways that schooling and justice systems were experienced by children living in care, has failed to fully engage with the experiences of Aboriginal children. Historians have given limited attention to the experiences of Aboriginal children living in institutions off Aboriginal reserves in Victoria. There has been limited historical scholarship examining the experiences of Aboriginal and Torres Strait Islander children at Tally Ho. This paper broadens our understandings about how Aboriginal children encountered institutionalisation in Victoria.
