Effect of project-based learning on high school students' state-mandated,standardized math and science exam performance

In a technologically driven society, math and science students in the United States are falling further and further behind their international counterparts, resulting in an influx of STEM focused, reformed K-12 schools, including schools focused on project-based learning (PBL). This article reports a study of the effectiveness of PBL on high school students' performance on state mandated standardized mathematics and science achievement measures. Manor New Tech High School is a nationally recognized model STEM school, with a diverse student population, where all instruction is delivered through PBL. Although there is ample research suggesting that PBL is advantageous for increasing STEM learning compared to conventional teaching approaches, there is a lack of studies randomly assigning students to receive PBL. Further, some of the effects observed for students attending project-based schools could be due to a self-selection bias for students or parents that choose such an alternative learning environment. This study addresses both of these concerns and found that students taught through PBL, as a group, matched performance of conventionally taught students on all science 11th grade and mathematics 9th, 10th, and 11th grade TAKS achievement measures and exceeded performance by a scale score increase of 133 for the 10th grade science TAKS measure by (B = 133.082, t = 3.102, p < .05). One possible explanation of the differences observed in this study could be the TAKS instrument used to capture student math and science achievement that interprets “real-life applications” of content differently between math and science questions. These results align with literature on the effects of PBL and deepen our understanding of these effects by providing a controlled study with random assignments to the PBL experience. Future research looking at the effect of PBL on achievement on the PISA could be beneficial in identifying benefits of PBL implementation in schools.     

Development and Assessment of a Three-Dimensional Tooth Morphology Quiz for Dental Students

Tooth morphology has a pivotal role in the dental curriculum and provides one of the important foundations of clinical practice. To supplement tooth morphology teaching a three-dimensional (3D) quiz application (app) was developed. The 3D resource enables students to study tooth morphology actively by selecting teeth from an interactive quiz, modify their viewpoint and level of zoom. Additionally, students are able to rotate the tooth to obtain a 3D spatial understanding of the different surfaces of the tooth. A cross-over study was designed to allow comparison of students’ results after studying with the new application or traditionally with extracted/model teeth. Data show that the app provides an efficient learning tool and that students’ scores improve with usage (18% increase over three weeks, P < 0.001). Data also show that student assessment scores were correlated with scores obtained while using the app but were not influenced by the teaching modality initially accessed (r² = 0.175, P < 0.01). Comparison of the 2016 and 2017 class performance shows that the class that had access to the app performed significantly better on their final tooth morphology assessment (68.0% ±15.0 vs. 75.3% ±13.4, P < 0.01). Furthermore, students reported that the 3D application was intuitive, provided useful feedback, presented the key features of the teeth, and assisted in learning tooth morphology. The 3D tooth morphology app thus provides students with a useful adjunct teaching tool for learning dental anatomy. Anat Sci Educ 00: 000–000. © 2018 American Association of Anatomists.     

儿童青少年骨骼肌相关体适能测试的10大研究问题

摘要：本文的研究目的是引起人们对儿童青少年骨骼肌相关体适能测试的10个亟待解决的问题的关注,目标是激发更多的研究来解答这些问题。这些急需解决的问题包括明确儿童青少年肌肉力量、爆发力（power）、耐力、柔韧性的有效、可信、可行的场地测试方法与健康风险因素/标记物之间的关系;确定运动训练对这些关系的影响;记录追踪这些关系。需要仔细并有针对性地检验柔韧性在健康相关体适能（HRPF）中的作用。体重/体成分在健康相关体适能中是一个独立的组成部分,但它也是一个能够影响骨骼肌测试项目成绩的因素。体重,体脂肪和中心性肥胖以及对这些测试结果进行调整的可能性都是非常重要的研究问题。有几个问题是关于哪些场地测试最适用于学校。最后,需要建立真正的健康相关体适能测试参考标准的界值点。总的来说,为了青少年HRPF,需要在骨骼肌领域进行更多高质量的研究。     

“钱学森之问”与高考作文命题——中美两国高考作文命题比较

中美两国高考作文命题存在较大差异。从写作对象看,中国题主要关注＂社稷＂,美国题主要关注＂个体＂。从价值判断看,中国题比较＂实＂,美国题比较＂虚＂。从材料限定看,中国题比较＂虚＂,美国题比较＂实＂。从可能的表述倾向看,写中国题易引出＂宏论＂,写美国题易导向＂实证＂。

中国小学生解决国外数学试题分析

通过中国小学生解决国外数学试题的分析 ,探讨中国基础教育现状 ,为数学教学改革提供实证研究基础。我们从国外数学测试中筛选、改编了一套小学五年级数学试卷 ,在全国九个省、市做了测验。结果显示 ,中国学生在考察基础知识的项目中表现出色 ;但在考察利用已有的生活经验解决问题的项目中 ,存在着相当的问题。因此 ,中国数学教育在重视基础知识的同时 ,应该引导学生有意义地理解数学、灵活自主地选择数学方法解决问题。     

高职生性格测验及其数学模型的研究

采用卡特尔性格测量表（16PF）对1310名在校高职生进行测试，结果表明，在校高职生的活泼性一影响性、交际性．乐群性等分值水平较高；独立性、怀疑性、情感性、有恒性等性格因素分值水平较低。在16PF性格因素与大一新生入学成绩及大二、大三学生在校学习成绩对照研究中发现，独立性（r=0．11）、世故性（r=0．11）、有恒性（r=0．13）、怀疑性（r=0．12）、自律性（r=0．11）、变革性（r=0．11）等与学习成绩呈高度正相关（r〉0．1）。
