This is a description of the conceptual foundations used for designing a novel learning environment for mechanics implemented as an "Industrial Educational Laboratory"--called Fisica in Moto (FiM)--at the Ducati Foundation in Bologna. In this paper, we will describe the motivation for and design of the conceptual approach to mechanics…

Purpose: Using data from children who spoke various nonmainstream dialects of English and who were classified as either children with specific language impairment (SLI) or typically developing (TD) children, we examined children's marking of infinitival TO by their dialect and clinical status. Method: The data came from 180 kindergartners (91…

Purpose: This study used perceptual and acoustic measures to examine the time course of speech adaptation after the attachment of electromagnetic sensor coils to the tongue, lips, and jaw. Method: Twenty native English speakers read aloud stimulus sentences before the attachment of the sensors, immediately after attachment, and again 5, 10, 15,…

This study determined the effect of a sound field amplification system on teacher movement in physical education (PE) settings. Two middle school PE teachers instructing coeducational PE classes were used as the subjects. This investigation used a multiple-baseline single-case design across subjects. The treatment (independent variable) was the…

In this paper, we describe the analysis of multimodal data collected on small collaborative learning groups. In a previous study, we asked pairs (N=84) with no programming experience to program a robot to solve a series of mazes. The quality of the dyad's collaboration was evaluated, and two interventions were implemented to support collaborative…

How do infants plan and guide locomotion under challenging conditions? This experiment investigated the real-time process of visual and haptic exploration in 14-month-old infants as they decided whether and how to walk over challenging terrain--a series of bridges varying in width. Infants' direction of gaze was recorded with a head-mounted eye…

Both students and teachers have misconceptions about Force and Motion, often caused by teachers not being well-prepared to teach the accepted scientific theory. Besides, teachers rarely or never use a cognitive conflict strategy in their teaching. The present study is aimed at investigating the use of a discrepant event to facilitate preservice…

In 1827, Robert Brown noticed pollen suspended in water bouncing around erratically. It wasn't until 1905 that Albert Einstein provided an acceptable explanation of the phenomenon (Kac 1947): Brownian motion is the random movement of particles (e.g., pollen) in a fluid (liquid or gas) as a result of collisions with atoms and molecules. Movement of…

Skill-related fitness is broken down into six different components; agility, speed, power, balance, coordination, reaction time. These skill-related components are movements that are necessary for an individual to successfully demonstrate a variety of motor skills and movement patterns. While essential, these skill-related components of fitness…

This study aimed to assess the validity and reliability of jump assessments using the "MyJump2" application. Eleven junior athletes (15 ± 1.4 years) performed five countermovement (CMJ) and drop jumps (DJ) measured simultaneously by a force platform and "MyJump2." Additionally, intra- and inter-day reliability was assessed over…

Countermovement jump (CMJ) height is an important parameter in physical performance. This study compared CMJ height measured using ChronoJump contact mat (CJ) and Myotest accelerometer (MT) systems with a force platform (FP). Thirty recreationally active adults (32.1 ± 10.4 years, 75.9 ± 12.0 kg, 173.2 ± 6.3 cm) completed a CMJ protocol where…

Rotational motion is ubiquitous in nature, from astronomical systems to household devices in everyday life to elementary models of atoms. Unlike the tangential velocity vector that represents the instantaneous linear velocity (magnitude and direction), an angular velocity vector is conceptually more challenging for students to grasp. In physics…

A spinning top or a spinning hard-boiled egg is fascinating to observe since both objects can remain upright for a relatively long time without falling over. If spun at sufficient speed on a horizontal surface, the spin axis rises to a vertical position and the bottom end tends to remain fixed in position on the surface. If the initial spin is…

Purpose: This study examined the relationship between the acoustic measure relative fundamental frequency (RFF) and a kinematic estimate of laryngeal stiffness. Method: Twelve healthy adults (mean age = 22.7 years, SD = 4.4; 10 women, 2 men) produced repetitions of /ifi/ while varying their vocal effort during simultaneous acoustic and video…

Astronomy concept is regarded as one difficult topic in both teachers' and students' perspective even though it strongly appeals to the human mind. This concept requires imagination and the ability to use various skills and knowledge, for example, actual motion, relative position, and coordination of views from several points on the Earth to…
