The study explored the possibilities to improve students' argumentation ability concerning factors that affect dissolving, through the implementation of two versions of a teaching scheme, with and without particle theory. The participants (age range 10-11, n = 27) belonged to two fifth-grade classes of a primary school in Northern Greece. Data…

In this study, the aim is to analyze opinions of engineering students on science literacy. Research participants constitute of a total of 143 students attending construction engineering department in a university located in the Eastern Black Sea region of Turkey. In this study in which survey model was adopted, data obtained through a form…

Over the past decade an increasing number of studies across a range of domains have shown that the repeated performance of approach and avoidance (AA) actions in response to a stimulus leads to changes in the evaluation of that stimulus. The dominant (motivational-systems) account in this area claims that these effects are caused by a rewiring of…

This article reports two experiments in which the artificial orthography paradigm was used to investigate the mechanisms underlying learning to read. In each experiment, participants were taught the meanings and pronunications of words written in an unfamiliar orthography, and the statistical structure of the mapping between written and spoken…

Students' judgements of their own learning often exceed their knowledge on a given topic. One source of this pervasive overconfidence is fluency, the perceived ease with which information is acquired. Though effects of fluency on metacognitive judgments have been explored by manipulating relatively simple stimuli such as font style, few studies…

Projectile motion is a common phenomenon that is used in introductory physics courses to help students understand motion in two dimensions. Authors have shared a range of ideas for teaching this concept and the associated kinematics in "The Physics Teacher" ("TPT"); however, the "Hoop Challenge" is a new setup not…

Introductory physics labs often focus on a series of common experiments intending to teach the student the measurement side of physics. While these experiments have the potential to be quite instructive, we observed that our students often consider them to be boring and monotonous, which often leads to them being uninstructive. To combat this, we…

We propose discussions and hands-on activities for GCSE and A-level students, covering a fundamental aspect of nuclear physics: the concept of bonds and the energy released (absorbed) when a bond is created (broken). This is the first of the series of papers named "A teaching guide of nuclear physics", whose main goal is to provide…

Science assessments should evaluate the full complement of inquiry practices (NGSS, 2013). Our previous work has shown that a large proportion of students' open responses did not match their scientific investigations (Li et al., 2017a). The present study both unpacks and compares the sub-components underlying students' performance for…

Magnetism and its various applications are essential for our daily life and for many technological developments. The term "magnetism" is almost always used as a synonym for ferromagnetism. However, the magnetic properties of the elements of the periodic table indicate that the vast majority of elements are not ferromagnetic, but rather,…

A long time ago in a galaxy far, far away, two black holes, one of mass 36 solar masses and the other of mass 29 solar masses, were dancing their death waltz, leading to their coalescence and the emission of gravitational waves carrying away with them three solar masses of energy. More precisely, it happened 1.3 billion years ago at a distance of…

The purpose of this experiment was to determine the effects of the meaningful addition of vegetables, using cauliflower and zucchini, to a pizza crust on the likeability of taste, texture, appearance, and overall preference of the pizza. The likeability testing revealed that the cauliflower variation produced an unacceptable product in texture,…

Purpose: The purpose of this study was to investigate the aging effect on the categorical perception of Mandarin Chinese tones with varied fundamental frequency (F0) contours and signal duration. Method: Both younger and older native Chinese listeners with normal hearing were recruited in 2 experiments--tone identification and tone discrimination…

This article reviews PsyToolkit, a free web-based service designed for setting up, running, and analyzing online questionnaires and reaction-time (RT) experiments. It comes with extensive documentation, videos, lessons, and libraries of free-to-use psychological scales and RT experiments. It provides an elaborate interactive environment to use (or…

Given the many older criticisms of Milgram's obedience study and the more damning recent criticisms based on analyses of materials available in the Milgram archives at Yale, this study has become a contentious classic. Yet, current social psychology textbooks present it as an uncontentious classic, with no coverage of the recent criticisms and…
