Penerapan heutagogi gamifikasi terhadap evaluasi pembelajaran geografi di sekolah menengah pertama

Evaluasi pembelajaran dalam bentuk tes sering menimbulkan kecemasan pada diri siswa sehingga mempengaruhi hasil belajar terutama pada pelajaran yang membutuhkan konsentrasi dan daya ingat seperti pelajaran Geografi. Untuk menciptakan suasana evaluasi belajar yang santai dan tidak membuat siswa merasa cemas, dapat dilakukan dengan memanfaatkan game edukasi sebagai alat evaluasi pembelajaran. Game didesain dan dibangun seatraktif mungkin untuk siswa kelas IX SMP dengan aplikasi Java 3D dengan. Game edukasi yang user-friendly, mudah diaplikasikan dan atraktif membuat siswa tidak sadar bahwa sebenarnya ia sedang dievaluasi. Pemanfaatan game edukasi sebagai alternatif media evaluasi pembelajaran mampu mengurangi kecemasan siswa dan membuat hasil evaluasi belajar lebih mendekati kemampuan siswa yang sebenarnya. Dari Hasil Uji Coba Fleksibilitas dan user friendly dengan mekanisme black box mendapatkan nilai 87,3%, hal ini menandakan konsep gamifikasi berjalan secara maksimal.

A Kind of Integrated Model for Panorama, Terrain and 3D Data Based on GML

Panorama image can provide 360 degrees view in one hotspot, which could solve the traditional three-dimensional expression of inadequate authenticity, difficult data acquisition as well as laborious and time-consuming modeling. However, we need other geographic information. So we propose a kind of integrated model based on GML, which contains a set of data structures to obtain panorama, terrain and 3D Data rapidly from the GML file, after analyzing GML files structure and parsing by the Document Object Model (DOM). The experiment shows that integrated model is very validated in web application using PTViewer, Java 3D and Web-related technologies.

Development of Multimedia Environment for Viewing the State of Stress in a Differential Element

The aim of this work is to present a tool developed in a multimedia environment of a cilitate the understanding of the state of plane stress at an infinite simal element, which is directed to lectures in Mechanics of Materials courses. This multimedia resource was developed in Java 3D API, liked an applet, as it is a simple language whose programs can run on all operating system platforms, using the virtual machineconcept. The multimedia resource determines the strains caused by forces acting in a solid body. Usingthis tool the learning process can be more efficiently, and the view of results at an differential element in the state of plane stress can be easier too.

Brep Model, VOXEL Model, and its Inner Attributes

By using dexelization algorithms, a Brep model is transformed to the three direction DEXEL model and VOXEL model. In the VOXEL model, every VOXEL could have its attributes such as color, or transparence. The attributes of the VOXEL model could be set and the inner attributes of a 3D model could be expressed. The VOXEL model and its inner attributes setting are very important for the design of complex models with complex inner attributes. Under Java2.0 and Java 3D, these algorithms were tested and some design examples were given.

Bezier Surfaces and Texture Mapping Using Java 3D

By using Bezier surface matrix formula and the algorithms of texture mapping, the texture mapping onto Bezier surface and its control points net were tested. The texture mapping for Bezier surface model that is composed of six Bezier surfaces was tested too. From the testing examples, it is concluded that these texture mapping algorithms are reliable. All algorithms were implemented by Java and Java 3D.

The 3D Computer Game Design Using Java 3D

In this thesis, the two 3D computer games were designed by Java 3D. In the first game, by using 3DMax, one aircraft carrier, one helicopter, submarines, warships, and destroyer escorts etc were designed. By using Loader3DS of MicrocrowLoader in Loader3DS1_2.jar or ModelLoader of Java 3D, these 3D models are loaded into the Java 3D. The second 3D game displays the 3D fighting and collision of tanks. This function is very important for the 3D game design. By using textures, the different appearances of 3D models were designed. By using Java 3D classes such as Alpha and PositionPathInterpolator and Sounds etc, the motions of 3D models and interactions and the sounds were defined.

Interactive Virtual Reality Cognitive Learning Model for Performance Evaluation of Math Manipulatives

Applications of virtual reality in E-Learning are gaining more popularity due to its interactive characteristics of virtual environments that can be offered. One unique example of this application is the use of virtual manipulatives, since they can be implemented on PCs economically for teaching students interactively in schools and universities. They enable students to learn mathematics thoroughly by easily providing computer-generated dynamic objects, allowing them to explore abstract mathematical concepts in a handson mode experince. In this paper, an implemented virtual reality based math virtual manipulatives is presented. A cognitive virtual reality learning model is also introduced. Performance evaluation of the virtual manipulatives, for several case studies, is achieved. Comparisons between the 2- Dimensions (2D) Java applets from National Library Virtual Manipulatives (NLVM) and the developed Java 3D Virtual Reality Math Manipulatives (VRMM) cases are performed. Results of the practical analysis for student grades show that VR enhances student learning of addition and subtraction operations in the VRMM, and it achieves superior results than the NLVM.

The Design of Artificial Porous Human Bone and RP Procedure Simulation

In design of artificial bones, in order to make it live together with the human bone, it should has the same porous structure as the human bone. But the Brep or solid model can’t achieve this. By transforming the three direction DEXEL model of polyhedrons into its VOXEL model and setting transparency attributes of VOXELs, the porous structure of artificial bone could be designed. By merging the same attribute VOXELs along y axis, a big VOXEL is formed. By this big VOXEL, the once sintering procedure of RP laser head is simulated. Layer by layer, the whole product is produced. Under Java2.0 and Java 3D, these algorithms were tested and some design examples were given.
