Physics @ Singapore platform.

Main Theme:

The central theme of this resource is to provide a simple, interactive tool for students to experiment with basic geometric shapes, specifically those constructed from equilateral triangles. The goal is to facilitate hands-on learning and exploration of shape composition, arrangement, and pattern formation in a 2D environment.

Key Information and Ideas:

• Interactive Learning Tool: The resource is described as an "interactive HTML5 Javascript Applet," emphasizing its digital and engaging nature. This allows students to actively manipulate shapes rather than passively observing them.
• Shape Construction Based on Equilateral Triangles: A fundamental characteristic of the applet is that "Each of the available shapes is constructed using an equilateral triangle as its base, with the area of each shape being a multiple of the area of the base triangle." This provides a consistent and mathematically grounded foundation for the shapes used in the activity.
• Shape Manipulation: The applet allows students to interact with the shapes by enabling them to "construct and build larger geometric shapes of varying sizes." Furthermore, students are provided with toggles to "rotate and erase existing shapes in the play area," offering flexibility in their experimentation.
• Objective: Exploration and Pattern Formation: The primary aim of the interactive is "to simply allow students to experiment with different combinations and arrangements of shapes to form interesting patterns and figures." This highlights a focus on open-ended exploration and creative problem-solving rather than achieving a specific predetermined outcome.
• Target Audience: While not explicitly stated in detail in these excerpts, the mention of "E2K" (Excellence 2000, a Singaporean educational program often aimed at higher-ability students) under "2D Shapes" suggests that this applet could be used with a range of students, potentially including those in enrichment programs. The description as "basic shape building" also implies suitability for younger learners.
• For Teachers: The inclusion of a "For Teachers" section indicates that this resource is designed to be integrated into educational settings. This section, while currently containing "[texthttps://iwant2study.org/lookangejss/math/ejss_model_shape_assembly3/) give direct access to the simulation.
• Credits: The applet is credited to "shaun; lookang" and the applet itself, mentioned in the second source, reiterates this authorship and indicates compilation using "EJS 6.1 BETA (201115)" and release under a specific license (though the specific license details are not fully provided in the second excerpt).
• Context within Open Educational Resources / Open Source Physics @ Singapore: The applet is presented within a broader context of open educational resources focused on physics and mathematics from Singapore. The extensive list of other interactive applets on the same platform demonstrates a commitment to providing a wide range of digital learning tools across various science and math topics. Many of these other resources also appear to be developed using JavaScript and HTML5, suggesting a consistent technology stack for these interactives.
• Potential Learning Goals: The "Sample Learning Goals" section, currently containing "[text]," would typically outline the intended learning outcomes for students using the applet.
• Relation to Other Resources: The lengthy list of other resources suggests a rich ecosystem of interactive learning tools available on the platform, covering diverse topics from physics simulations to math games and language learning activities. The repeated mention of JavaScript HTML5 applets indicates a common development approach.

Quotes:

• "This is a simple interactive, where students can use the available shapes to construct and build larger geometric shapes of varying sizes."
• "Each of the available shapes is constructed using an equilateral triangle as its base, with the area of each shape being a multiple of the area of the base triangle."
• "Students are also allowed to rotate and erase existing shapes in the play area via the toggles provided."
• "The objective of this interactive is to simply allow students to experiment with different combinations and arrangements of shapes to form interesting patterns and figures."

Overall Significance:

The "Basic Shape Building Interactive HTML5 Javascript Applet" offers a valuable, freely accessible tool for teaching and learning basic geometric concepts. Its focus on hands-on manipulation and exploration aligns with constructivist learning principles, allowing students to actively engage with shapes and develop their spatial reasoning and pattern recognition skills. The integration within a larger open educational resource platform enhances its potential impact and accessibility for educators.

Basic Shape Building Interactive HTML5 Javascript Applet Study Guide

Description of the Interactive:

The Basic Shape Building Interactive HTML5 Javascript Applet is a simple tool designed to allow students to explore the construction of larger geometric shapes using smaller, pre-defined shapes. The fundamental building block for all available shapes is an equilateral triangle, and the area of each shape in the applet is a multiple of the area of this base triangle. Users can manipulate these shapes within a designated play area, arranging them in various combinations to form different patterns and figures. The applet provides toggles that enable users to rotate and erase shapes within the play area, facilitating experimentation and exploration of spatial relationships. The primary goal of this interactive is to provide a hands-on environment where students can freely experiment with geometric shapes, discover how they fit together, and develop an intuitive understanding of geometric composition.
