AppVidya為學生提供在線上門補習馬鞍山服務,並使他們有機會繼續深造。查布拉說,直到大流行之前,它一直在起飛。

查布拉說:“我們幾乎不知道這種流行病將席捲全球。” “那時我知道有這麼多的學生根本沒有接受任何 上門補習 馬鞍山教育。最初,我只是幫助處於經濟困境的學生,但我想為所有人做到這一點。”

當他被隔離時,由於無法返回他的第二故鄉霍奇基斯學校,CoVidya出生了。

他說:“借助CoVidya應用程序,我的目標是為需要它的任何人提供免費輔導。” “它適用於世界上任何地方的任何學生。”

尋找幫助CoVidya學生的導師很快發生了。 “我打電話給我認識的每個朋友。我打電話給香港政府,並與香港政府的少數民族事務司建立了聯繫,”查布拉說。 “我還問人們是否想教書。當我在Reddit上發布《南華早報》的故事後,我一口氣就得到了幾百名導師。那是對項目的極大推動。”

他的回應使他感到鼓舞。

他說:“讓所有這些人簽約表明了很多人的善意,他們願意付出時間並幫助學生。” “看到我有多少老師,真是令人心動。”

他說,上門補習招聘計劃是在亞洲大流行期間採用的,現在,亞洲國家正逐漸擺脫檢疫,該計劃將繼續下去。

查布拉說:“如果有人想教些東西,無論是大學生還是教授,他們所要做的就是在他們幾個小時的時間內做志願者。”

查布拉(Chhabra)現在正在努力將美國包括在內。“美國康涅狄格州是我一年來度過的9個月,”他說。 “康涅狄格州是我的家。當然,人們也被困在家裡,可以從補習中受益。”

為世界各地的學生提供輔導服務的過程中,一部分是使個人彼此匹配。他說:“起初我是自己做的,然後我在線開發了一個腳本,以幫助進行配對過程,找到哪個學生最適合每個導師。” “如果規模真的很大,將需要大量的人力,但是如果發生這種情況,我會做好準備。該腳本可自動進行配對。”

對CoVidya感興趣的任何學生或專業人士都可以訪問www.appvidya.com/covidya進行註冊。 “您也可以在此處了解有關該項目的更多信息,” Chhabra說。

查布拉說,他正在協助CoVidya,但也要保持忙碌。他說:“這給我要做的事情。” “這比浪費時間玩視頻遊戲要好。

“我一直對計算機,編碼和計算機上的語言感興趣。 ……我一直具有科學STEM背景,我出生於一個非常重視教育的家庭,”他說。 “我相信教育是我們擁有的最好武器。這就是背後的動機。”

在Hotchkiss之前,Chhabra就讀於香港Harrow國際學校的一所英國學校,並與他的母親Sonu Govil和父親Amit Chhabra住在一起。在過去的三個暑假中,他參加了一些課程:約翰·霍普金斯大學的高級物理學課程,是其青年人才中心計劃的一部分,該課程是根據國際人才搜尋和他的數學成績選拔出來的。 2018年,他參加了杜克大學(Duke University)的編碼和機器人技術計劃,這是學校人才識別計劃的一部分。在2019年,他被西北大學的數學課程錄取為人才培養中心計劃的一部分。

他說:“今年夏天,我實際上參加了一個創業計劃LaunchX,在那裡我將創辦自己的初創公司。” “秋天我會回到霍奇基斯。”

在霍奇基斯大學,查布拉是學校報紙的編輯兼作家,並喜歡辯論。他還是網球運動員,鼓手,並且喜歡看電影。但他說,他對教育技術充滿熱情。

他說:“我會盡我所能幫助他人。” “我從未參加過編碼課程,但是今年我很想在Hotchkiss參加一門課程。否則,這就像我在杜克大學上的課程一樣,都是自學的。”

局外人可能會認為Chhabra已經踏上了新職業,但目前還不確定。

他說:“這將屬於STEM領域。” “目前,我專注於此。從長遠來看,我想繼續使用創業技術。但是我沒有具體的計劃。”
