Abstract
This research is experimental research aimed to study the effect of using chatbot in blended learning. The chatbot was used to present and review studying content. Students can do exercises via the chatbot in order to increase the learning achievement. It is a text-based conversational chatbot with teenager personality and was designed to be easily accessible via the Facebook Messenger. It uses Natural Language Processing (NLP) to translate conversational messages into the intents according to the conversational context. The experimental designs were Pretest Posttest Control Group Design used to compare the learning achievement of students, and Static Group Comparison Design used to compare the working memory of students. The Population was vocational certificate students in the colleges under the Institute of Vocational Education Northeastern Region 1. The 2 classrooms of samples were firstly selected using clustering random sampling method, then 60 divided into 2 groups, namely the experimental group consisting of 30 students learning with blended learning using the chatbot, and the control group consisting of 30 students learning with traditional method. The content was the Basic Hydrocarbon Compounds in the Science for Life Skills Development course. The research instruments consisted of the chatbot for blended learning, the achievement test, and the students’ working memory test. The data were analyzed using the mean and standard deviation. The differences of the learning achievement and the students' working memory of both groups were compared using independent sample t-test statistics. The results showed that the learning achievement and the working memory of the experimental group were significantly higher than the control group at a statistical level of .01.
