The falling rod paradox, i.e. the fact that the tip of an almost horizontal rod falls with an acceleration 'higher than g', when the other end is hinged or supported, is a popular physics demonstration. It can be visualized by placing e.g. a coin on the tip of the rod and fixing a cup next to the coin. When the rod is released the free-falling…

Acceleration is a well-researched educational intervention supporting positive outcomes for high-ability students. However, access to acceleration may be restricted due to educators' misapprehensions about this practice. To better understand whether students share educators' concerns, our study explored 26 high-ability students' beliefs about…

With more students returning to in-person instruction, school systems can begin to shift their focus from surviving the crisis to helping students recover. Above all else, that means accelerating students back to grade level--not by rushing through the curriculum, but by using proven strategies that help students engage with the most critical work…

Most people associate summer with activities that have nothing to do with school, or, if they do, summer school comes to mind -- the remediation variety. Historically, summer school is for struggling students who need to relearn and firm up skills from prior years or for those required to retake a class. But what if it could be reimagined how to…

The motion of a cylindrically or spherically symmetric body on an accelerated treadmill, inclined of an angle [theta] with respect to the horizontal, is described by means of Newtonian mechanics. By assuming that the conveyor belt has an acceleration "a[subscript O][superscript ']", not necessarily constant, and that the body rolls on…

A phone emitting sound of a fixed frequency is sliding on an inclined plane and approaching a second phone kept at the bottom of the plane. The detected frequency versus time data by the second phone are used to calculate the acceleration of the sliding phone. The primary objective of this paper is to calculate the sliding friction between the…

The aim was to establish which postural and physical activity outcomes are comparable across different accelerometer brands worn on the thigh when processed using open-source methods. Twenty participants wore four accelerometers (Axivity, ActiGraph, activPAL, GENEActiv) for three free-living days. Postural and physical activity outputs (average…

Recent trends in developmental education (DE) include the reduction of time spent in DE courses, which includes the acceleration of the course content. In 2011, the North Carolina Community College System redesigned all DE mathematics courses using this trend of acceleration. This study looks at the subsequent gateway mathematics course success…

This study used a case study research design to investigate the knowledge, perceptions, and beliefs of elementary principals regarding whole-grade acceleration for gifted students. The research literature is overwhelmingly positive on student outcomes--academically, socially, and emotionally. However, little research exists on the impact of…

The standing vertical jump (SVJ) is a classical topic in Newtonian mechanics (Fig. 1). Although the topic has also been treated by others (other terms used are "standing high jump" or "squat jump"), the present paper shows how a smartphone can be used to capture video of a jump and determine the jump height. A crucial…

It is commonly accepted that repeatedly using mental procedures results in a transition to memory retrieval, but the determinant of this process is still unclear. In a 3-week experiment, we compared two different learning situations involving basic additions, one based on counting and the other based on arithmetic fact memorization. Two groups of…

The trajectory of a ball in air is affected by aerodynamic drag and lift. In general, the trajectory needs to be calculated numerically since the acceleration varies with time in both the horizontal and vertical directions. If the trajectory remains approximately parabolic, then simple analytical solutions can be found, giving useful insights into…

For many years, Atwood's machine has been used to demonstrate, illustrate, or verify Newton's laws in introductory physics courses. It consists of two objects of different mass that are fastened to the ends of a string that hangs over a pulley. In an idealized situation, one assumes that pulley friction, the string's mass, and changes in the…

There is the need to liberate the school science teaching process to suit the culturally bound day-to-day experiences of learners. The clarion call becomes expedient in the light of pedagogical failure in science education, which precipitates poor science achievement, especially in non-Western cultures. Non-Western knowledge systems, specifically…

In recent years, smartphone sensors have been frequently used in educational demonstrations to improve students' understanding of certain physical kinematic topics. In particular, the sensors on modern smartphones enable students to use their phones as physics mini-laboratories, and they have been used to analyze objects' speeds and accelerations…
