An investigation of the mathematics applications in the Apple App Store: Do they contain benchmarks of educational quality?
No full textGiven the numerous mathematics applications marketed in the Apple App Store and the lack of quality control, it is critical to determine whether these digital learning tools are well-designed and if they are accurately marketed by developers. The present study evaluated the top math apps (n = 33) priced under $15, categorized into three age groups (i.e. <5, 6-8, and 9-11) in the App Store. It examined how well they incorporate five educational features or benchmarks in their apps, namely- scaffolding, feedback, learning theory, math subjects, and content integration (i.e. the connection between game and learning content). Furthermore, it assessed whether developers mentioned these benchmarks in their store descriptions and if the descriptions accurately reflected the app's content. Most apps included more than three benchmarks. All apps contained feedback and learning theory and most provided some forms of scaffolding. The types and amount of math subjects, feedback, and scaffolding varied significantly across apps. Interestingly, these top apps contained more benchmarks and content than developers advertise in the App Store. The findings emphasize the importance of developers incorporating benchmarks into their apps and accurately communicating this to the public to help them navigate the sea of available apps.Social Sciences and Humanities Research Council of Canada [435-2021-0612]Funding for this work was provided by the Social Sciences and Humanities Research Council of Canada (435-2021-0612)

Enhancing indoor thermal comfort in buildings using innovative foam concrete with phase change material
No full textEnergy consumption can be reduced by improving thermal performance of buildings and using energy efficiently. This can be achieved by integrating phase change material (PCM) with heat storage properties into foam concretes in building envelopes. The present study aims to prepare diatomite/capric acid (CA) composite, integrate it into foam concrete structure and enhance thermal energy performance of buildings under real weather conditions. For this purpose, it was first determined that diatomite could absorb capric acid at a maximum of 50 % (by weight) without leakage by direct impregnation. The prepared diatomite/CA composite was incorporated to foam concrete mixture as a substitute for sand aggregate at four different ratios of 15 %, 20 %, 25 % and 30 %. For diatomite/CA composite, melting and freezing temperatures and enthalpy values were found to be 28.73 degrees C and 28.49 degrees C, and 101 J/g and 193 J/g, respectively. While spreading diameter and dry unit weight values decreased as the ratio of diatomite/CA rose, water absorption and apparent porosity values increased. Thermal conductivity and compressive strength decreased depending on the increase in amount of diatomite/CA. For foam concrete with 30 % diatomite/CA, the highest water absorption, apparent porosity and compressive strength were measured as 25.9 %, 34 % and 6.31 MPa, respectively. Thermal conductivity varied between 0.495 and 0.241 W/mK. Thermoregulation test results demonstrated that foam concrete slabs containing 30 % diatomite/CA significantly improved indoor temperature regulation, achieving a cooling effect of approximately 3.7 degrees C during peak heat periods and contributing to a heating load reduction at night by maintaining indoor temperatures up to 8.8 degrees C warmer

The effect of variety-support in physical education on participation: the serial mediation role of enjoyment and motivation *
No full textAlthough adolescents' Physical Activity (PA) levels are associated with various benefits, PA participation rates remain low. Previous studies have revealed that one of the psychological factors that may have a significant impact on adolescents' PA and participation in Physical Education and Sport (PES) is perceived variety-support. The aim of this study is to examine the serial mediation role of enjoyment and motivation in the relationship between variety-support and participation in PES. For this purpose, firstly, the The Perceived Variety-Support in Physical Education Scale (PVSPES) developed by Eather et al. (2022) adapted to Turkish and applied to middle school (n=561) and high school (n=457) samples. CFA results showed that the Turkish version of the PVSPES was measurement invariant across gender and educational level. The study, which examined the serial mediation role of enjoyment and motivation in the relationship between variety-support and participation, was conducted using structural equation modeling with a sample of 1018 (532 female, 486 male) middle school (n=561) and high school (n=457) students. The findings of the study revealed that students' perceptions of variety-support in the PES had a significant positive direct effect on course participation. It was found that enjoyment (b = .086, BootSE = .014, 95% CI [.059, .115]) and motivation (b = .061, BootSE = .012, 95% CI [.039, .087]) mediated the relationship between variety-support and participation. The serial mediation model revealed that the serial mediation effect of enjoyment and motivation was significant in the effect of students' perception of variety-support on participation (b= .087, BootSE= .011, 95% CI [.067, .109]). As a result, it was found that students' perception of variety-support in PES increases enjoyment and motivation towards the courses, and as a result, both factors positively affect course participation through serial mediation. Offering a variety of activities to students in PES will increase their enjoyment and motivation towards the course and contribute positively to their course participation
