After a long but busy winter break, Grade 9&10students are back to school for a new semester! But before we start anything new, we must have a reflection of what we accomplished in the last semester. So on Feb. 21 and Feb. 25, severalgroups of students from different PBL classes presented and explained the projects they conducted.

Mr, Liao Huiand Ms. Chen Lin, the supervisorsof PBL course gave a brief summary of last semester. Then some students of excellent projects were invited to give a presentation. Students improved a lot through one semester’s learning in PBL class and showed their achievements in various forms. Posters, videos, slideswere used for presentation and the speeches were really impressive. Many students said that their collaboration skills were also improved a lot over the last semester.From the presentation, we found that several of theprojectswere experiments, including the fruit battery experiment, extracting the DNA of bacteria, designing ananti-earthquake building, and creating glow-sticks! Many of the experiments required high tech tools and advanced procedures. This was especially true for the biology PBL. Jennyexplained the procedure of first checking soil for bacteria and then testing the bacteria for a certain disease. She had the privilege to experience extracting the DNA of the disease and showed color coded pictures of her results! It was all very impressive. Others were similar to research projects where students either tried to solve the issue of garbage atSHSIDor analyzing a way to measure the quality of tea leaves. Yes, Leo gave an entertaining speech about his journey on how to measure the quality of tea leaves and it was quite impressive. Others were more curriculum based, such as behavior economics. The students in behavior economics first learned a lesson and then created a project.

During the presentation, they showed some of their previous posters. There were very creative and artsy drawings! As you can see, we accomplished much in the last semester. Let’s hope we achieve even more in this semester!

2月21日和2月25日，所有九年級(jí)和十年級(jí)的學(xué)生分別利用PBL（Project-based learning）兩節(jié)課的時(shí)間在先綿堂輔樓禮堂展示和分享了上學(xué)期PBL課程的成果與感想。

PBL是專門為了提高學(xué)生思考問題和解決問題的能力而開設(shè)的課程。與平時(shí)學(xué)科老師正常上課和布置作業(yè)的形式不同，PBL課程是在老師指引下主要由學(xué)生們自主的進(jìn)行學(xué)習(xí)和探究并完成課題項(xiàng)目。通過這個(gè)成果展示，同學(xué)們可以了解到其他PBL課程的內(nèi)容。

講座的開始，由PBL總負(fù)責(zé)廖輝老師和陳琳老師對(duì)上學(xué)期的PBL開展情況作了總體介紹，隨后他們邀請(qǐng)了部分優(yōu)秀項(xiàng)目的制作學(xué)生展示了他們一學(xué)期的成果。經(jīng)過一學(xué)期的學(xué)習(xí)，同學(xué)們的項(xiàng)目制作能力都得到大幅提高，成果展示形式多樣、精彩紛呈。展板、視頻、報(bào)告等各有特色，亮點(diǎn)頻現(xiàn)。例如在Nina，Dora，和Maureen同學(xué)的關(guān)于電磁小制作的演講里面，她們談到了在整個(gè)學(xué)期里面，她們做的實(shí)驗(yàn)設(shè)計(jì)，學(xué)習(xí)到的知識(shí)，以及對(duì)于這門課程的想法。又例如在Henry同學(xué)的演講里面他提到了如何利用數(shù)學(xué)的軟件，結(jié)合自己的知識(shí)來制作各種各樣有趣的圖形。我們可以發(fā)現(xiàn)，PBL課程的選項(xiàng)不僅豐富有趣，更涉及到各個(gè)不同的學(xué)科。這對(duì)大家來說既是挑戰(zhàn)也是機(jī)會(huì)。不少同學(xué)還表示，通過PBL的學(xué)習(xí)，團(tuán)隊(duì)合作能力也得到了很大的鍛煉。

精彩的展示進(jìn)一步激發(fā)了學(xué)生新學(xué)期的選課熱情，大家都紛紛表示有很多感興趣的課程想要嘗試。不知道這個(gè)學(xué)期的PBL課程，他們又將會(huì)做出怎樣的選擇，將會(huì)創(chuàng)造出怎樣的作品呢？就讓我們一起拭目以待吧！
