Dynamic Google SketchUp Software and Conventional Teaching Strategy of Students’ Conceptual Knowledge and Procedural Knowledge in Learning Geometry

The purpose of this study is to identify the effect of using dynamic software Google SketchUp (GSU), without software on van Hiele’s theory and conventional teaching strategy of students’ conceptual and procedural knowledge in learning geometry among primary school students. The study was conducted using pre and post-test true experimental methods. This true experimental research involved 96 students from Year Five primary schools in Malaysia. The selection of site or school take into account as convenience and voluntary participation. The study's findings showed significant differences in student's conceptual knowledge and procedural knowledge based on the different types of the strategy group. The post hoc test indicated that using software showed better conceptual and procedural knowledge when compared to without using software on van Hiele’s theory and conventional teaching strategy.

Technical-Economic Evaluation of the Effectiveness of Measures Applied to the Artificial Lighting System of a School

Ensuring optimum interior lighting is a topic of great importance, as this influences not only the well-being of users but also the optimal performance of visual tasks. Lighting can be natural, but if not sufficient, it can be compensated with artificial lighting. This study highlights a methodology for designing a new lighting system that takes into account both technical and economic aspects. The method was applied to an existing school located in southern Italy, in which the electricity consumption is related to the current lighting system. The school is chosen as being representative of the construction type and layout of many local schools. In addition, the coexistence of several visual tasks with different design requisites (e.g., illuminance levels) makes the school a very complex environment. The school lighting is modelled in Google SketchUp and imported into Daysim to simulate the yearly and hourly daylight indoor contribution. Dialux Evo has been used to simulate and design artificial lighting. The results show a reduction of energy consumption of 33% with the simple replacement of fluorescent luminaires with LEDs, while the LED lamp dimming and modulation for rows of luminaires leads to a 95% reduction in energy consumption compared with the current state.

Validated TRNSYS Model for Solar Assisted Space Heating System

The present study involves a validated TRNSYS model for solar assisted space heating system as applied to a residential building in Jordan using new detailed radiation models of the TRNSYS 17.1 and geometric building model Trnsys3d for the Google SketchUp 3D drawing program. The annual heating load for a building (Solar House) which is located at the Royal Scienti?c Society (RS5) in Jordan is estimated under climatological conditions of Amman. The aim of this Paper is to compare measured thermal performance of the Solar House with that modeled using TRNSYS. The results showed that the annual measured space heating load for the building was 6,188 kWh while the heati.ng load for the modeled building was 6,391 kWh. Moreover, the measured solar fraction for the solar system was 50% while the modeled solar fraction was 55%. A comparison of modeled and measured data resulted in percentage mean absolute errors for solar energy for space heating, auxiliary heating and solar fraction of 13%, 7% and 10%, respectively. The validated model will be useful for long-term performance simulation under different weather and operating conditions.

The Effect of Google SketchUp and Need for Achievement on the Students’ Learning Achievement of Building Interior Design

This study aims to find out the effect of the Google SketchUp application and the need for achievement on students’ learning achievements of building interior design. Quasi-experimental research was conducted at the Vocational High School (VHS) with a 2 x 2 factorial design. The Google SketchUp application was used in the experimental group, while the PowerPoint Slides were used in the control group. The sample consisted of 56 VHS students, study program of modeling design and building information. The instruments used are need for achievement tests and learning achievement tests with reliability coefficients of 0.916 and 0.671. To test the hypothesis using multiple variance analysis techniques and the Tukey test. The results show that the Google SketchUp application is more effective than the PowerPoint in the learning of building interior design. Students who classified with a high need for achievement earn higher learning achievement compared to the lower one. There is an interaction between the Google SketchUp application and the students’ need for achievement. For students who have a high need for motivation, using the Google SketchUp application is more effective than using PowerPoint Slides. On the other side, the students who have a low need for motivation, the use of the Google SketchUp application does not differ significantly compared to the use of PowerPoint Slides. This finding is very useful for vocational teachers as an effort to improve the learning process of building interior design. However, it is also possible that these findings can apply more broadly to student learning in other skills competencies in VHS. These findings contribute to the management of vocational education as an effort to implement VHS revitalization. Furthermore, it also can be used as a consideration by the Head of VHS and decision-makers in the Ministry of Education and Culture.
