定性的方法进行研究，用定量Kington卡尼克。定量方法采用准实验设计。本设计的目的是评估配对性能对SRT以及比较它们的性能的基础上的友谊和了解，性别和能力。此外，认知任务参与本研究。为了鼓励学生参与，这个任务很难分析，理解或解决。它也必须允许合作伙伴采取各种观点，并提出了作为一个问题的任务。此外，该任务必须在科学的任务，因为说豪和tolmic（2003），“他们需要在一些认知领域的推理（如物质、数量、比例）”。NFER（1979）也表示，“年龄适当的任务是选择从大豆银行试行三年水平”。实际的工作应用：srt1（预测在一个倾斜的罐子；水位透视基于容器倾斜时的绘制与铅垂线方向预测）；和srt2（体积和重量，物质守恒，浮沉），定性的方法，它涉及了学生面试后完成了任务，分别做了。采访的重点是活动的学生参与的朋友和活动的例子，他们共享校内和校外。在采访过程中，有一些问题问他们。这些问题包括最好的朋友，课堂和学校活动，与朋友和课外活动的朋友进行的质量。
加拿大英属哥伦比亚理工代写论文:准实验设计
Qualitative and quantitative methods were used by Kutnick and Kington in this research. For quantitative method, it involved quasi-experimental design. The purposes of the design are to assess paired performance on SRTs as well as to compare their performance based on friendship and acquaintance, gender and ability. Besides that, cognitive task was involved in this research. To encourage students' participation, the task has to be difficult to analyse, understand or solve. It also must allow the partners to take a variety of point of view and present the tasks as a problem. Furthermore, the tasks must upon science tasks because as said by Howe & Tolmic (2003), "they involve reasoning in a number of cognitive areas (e.g. substance, quantity, proportionality)". NFER (1979) also stated that "Age appropriate tasks were selected and piloted from the banks of SRTs for the three Years levels". Actual tasks used in this study included SRT1 (prediction of water level in a tilted jar; perspective-based drawing and prediction of direction of a plumb line in a container when tilted); and SRT2 (volume and heaviness, conservation of matter, and floating and sinking).For qualitative method, it involved interview which had done after students completed the tasks individually. The interview was focused on activities the students involved with friends and examples of the activities that they shared inside and outside school. During the interview, there were some questions that had been asked to them. The questions included the qualities of best friends, classroom and school activities undertaken with friends and activities undertaken with friends outside the school.
