项目摘要

Project Summary: Students with blindness face explicit bias and systemic exclusion in chemistry. The chemistry laboratory remains especially inaccessible—“off limits”—to students with BLV. The exquisite 3D imagery of chemistry also remains inaccessible, as visualizing each image in a textbook would require a large hand-held model. Excluding students from the “central” science—from its tools, data, and imagery— can inhibit learning in other STEM fields. In the state of Texas, 11,000 children and young adults (age 0- 22) have blindness or low vision (BLV). The Texas School for the Blind and Visually Impaired (TSBVI) educates ~ 600 K-12 students per year. The objectives of this project are to increase access to chemistry labs, instrumentation, data, and imagery for high school students at TSBVI (grades 9-12). The project team involves: (i) five PhD-level chemists (three have been completely blind from childhood or birth), (ii) one special educator at Baylor University, (iii) five TSBVI teachers and accessibility specialists, and (iv) the Laboratory Safety Program Manager at Baylor University. Special Research Experiences (SRE’s) have been planned at Baylor University for 30 new TSBVI high school students per year. These two-day experiences will be accompanied by pre-lab and post-lab tactile curriculum, safety training, and role modeling from PhD chemists with blindness. In Aim 1, accessible curriculum is being developed for SRE’s via 3D printing, tactile printing, Braille printing, and audio recording. In Aim 1, millimeter-scale “micro models” of 3D images are also being designed and developed (as an alternative to conventional large tactile models). The ability of TSBVI students to visualize these micro models by oral and manual stereognosis is tested during SRE’s. In Aim 2, lab spaces at Baylor are being modified to be accessible to TSBVI students, to conduct the four SRE’s described in Aim 3. Outfitting the lab involves use of “high tech” solutions (e.g., robots that weigh, dispense and mix solids and liquids) and “low tech lab hacks”. In Aim 3, four different Special Research Experiences will be provided to 15 new TSBVI students per semester (students assigned a different SRE each year). Two SRE’s involve the synthesis of industrially important molecules, using a robotic reactor at Baylor University that is safely enclosed inside an air-tight, blast-proof glove box. Two other SRE’s allow students to use electron and atomic force microscopy and tactile printing to visualize nanoscale molecular assemblies (e.g., protein fibrils and carbohydrate scales of butterfly wings). The four experiences will provide students with knowledge of microscopy; mass spectrometry; simple organic reactions; and protein aggregation. Students will learn that they can visualize the highest resolution imagery from microscopy via tactile graphics. Students will learn that they can safely do chemical synthesis using robots inside glove boxes. The hypothesis, tested in a randomized control trial, is that SRE’s will increase TSBVI student interest, confidence, and sense of belonging in STEM.

项目摘要：失明的学生面临明显的偏见和化学中的全身排斥。这对于BLV的学生来说，化学实验室仍然尤其无法接近“限制”。独家3D 化学图像也仍然无法访问，因为在教科书中可视化每个图像将需要一个大型手持型号。将学生从“中央”科学中排除在其工具，数据和图像中 - 可以抑制其他STEM领域的学习。在德克萨斯州，有11,000名儿童和年轻人（年龄0- 22）患有失明或低视力（BLV）。德克萨斯州盲人和视力障碍学校（TSBVI）每年教育约600 k-12学生。该项目的目标是增加获得化学的机会 TSBVI高中生的实验室，仪器，数据和图像（9 - 12年级）。项目团队涉及：（i）五位博士学位化学家（三位从童年或出生开始完全失明），（ii）贝勒大学（III）的一名特殊教育家（III）五位TSBVI老师和可访问性专家，（iv）贝勒大学实验室安全计划经理。特殊研究经验（SRE）每年在贝勒大学计划为30名TSBVI高中学生计划。这两天经验将伴随前LAB和LAB后触觉课程，安全培训和角色从具有失明的博士化学家进行建模。在AIM 1中，正在为SRE开发可访问的课程通过3D打印，触觉打印，盲文打印和录音。在AIM 1中，毫米尺度“微型还设计和开发了3D图像的模型”（作为常规大型的替代方案触觉模型）。 TSBVI学生通过口头和手册可视化这些微型模型的能力在SRE期间测试了立体认知。在AIM 2中，正在修改Baylor的实验室空间以访问对于TSBVI学生，进行AIM 3中描述的四个SRE。配备实验室涉及使用“高 Tech”解决方案（例如，重量，分配和混合固体和液体的机器人）和“低技术实验室骇客”。 AIM 3，将为15个新的TSBVI学生提供四种不同的特殊研究经验学期（学生每年分配不同的SRE）。两个SRE涉及工业的合成重要的分子，使用贝勒大学的机器人反应堆安全地封闭在气密内，防火杂物盒。另外两个SRE允许学生使用电子和原子力显微镜以及触觉打印以可视化纳米级分子组件（例如，蛋白质原纤维和碳水合物尺度蝴蝶翅膀）。这四种经验将为学生提供显微镜知识；大量的光谱法；简单的有机反应；和蛋白质聚集。学生将了解他们可以可视化通过触觉图形从显微镜出发的最高分辨率图像。学生将了解他们可以安全使用手套箱内的机器人进行化学合成。该假设在随机对照中进行了检验审判是，SRE的会议将增加TSBVI学生的兴趣，信心和属于STEM的归属感。
