This study aims to design case-based learning with lesson study learning trajectory with the help of teaching aids to make students understand Prim's, Cruscal's, and Djiksra's Algorithms. The validation study was selected because it is a suitable method for this research. The research subjects were 41 Mathematics Education Study Program Students…

As well as knowledge structures can be complex and coherent, they might be small and disconnected. This study focuses on knowledge elements of pre-service teachers using diSessa's phenomenological primitives (p-prims) framework. Based on group interviews, a test was developed regarding the knowledge fragments used for explaining free fall in three…

The Primary Teacher Education (PrimTEd) project was established in response to concerns about the pre-service preparation of primary teachers in South Africa. In order to inform the development of appropriate pre-service mathematics courses, an initial need in the PrimTEd project was to establish the nature of the mathematical knowledge of…

Demonstration interviews with 27 high school students (18-19 years old) were conducted in Zagreb, Croatia, using several standard experiments on interference and diffraction of light. Students were asked for their predictions, observations, and explanations of the experiments. In this process, many student difficulties were identified, both…

Newtonian mechanics is still among the most difficult topics in the physics' syllabus taught at school. For example, even after completing traditional instruction, students still think that a force is necessary to maintain motion. Therefore, a revised method of instruction is needed that meets students' learning needs. The aim of the project…

The transition from high school to university is often a challenge for many students, as they face numerous academic and social adjustments during this time. For the 2020 cohort, these challenges were compounded by the COVID-19 pandemic which further exacerbated the existing concerns and uncertainties. This study reports on the perceptions of a…

Conceptions of ecological processes such as the flow of energy and cycling of matter in an ecosystem are increasingly important understandings in a rapidly changing world. This study utilizes a p-prims, or knowledge in pieces, lens to examine understandings and disconnections in students' conceptualizations of energy flow and matter cycling…

Within initial teacher education there is increasing pressure to enhance the use of assessment data to support students to improve their knowledge and skills, and to determine what standards they meet upon graduation. For such data to be useful, both programme designers and students require meaningful and comprehensive assessment reports on…

When California's students return to school this fall, schools can play a pivotal role in preventing, assessing, and addressing trauma in order to support students' well-being. We summarize the existing evidence base on multi-tiered trauma-informed practices that offer increasingly intensive tiers of support. Although many multi-tiered models of…

A power supply is needed to maintain the function of a computer, heat is needed to keep food from cooling down, and a force is needed to maintain motion. Those are notions that seem very natural to many people as they are based on everyday experiences. However, when it comes to motion, it is not force that maintains motion but momentum. Students…

The purpose of this autophenomenography was to explore our lived experiences in three world music pedagogy programmes. We participated in three different world music pedagogy programmes in the United States and Ghana. We gathered data through field notes and researcher journals, and by collecting interviews of other participants and…

Purpose: Although California school discipline policy changes over the past decade have resulted in significant drops in suspension rates, scholars have found that racial disproportionality in punitive discipline persists for Black, Indigenous, and at times Latinx students. This study utilizes racial capitalism as an analytical framework to…

This study compares the scientific and alternative conceptions of energy and momentum of university first-year science students in Ethiopia and the US. Written data were collected using the Energy and Momentum Conceptual Survey developed by Singh and Rosengrant. The Concentration Analysis statistical method was used for analysing the Ethiopian…

[This paper is part of the Focused Collection on Curriculum Development: Theory into Design.] Developing a solid understanding of simple electric circuits represents a major challenge to most students in middle school. In particular, students tend to reason exclusively with current and resistance when analyzing electric circuits as they view…

Background: Although early closure of formal youth mentoring relationships has recently begun to receive some attention, more information about factors that contribute to premature endings, and how those factors interact, is needed so that empirically-based program practices can be developed and disseminated to prevent such endings and to ensure…
