A Trip Intensity Model on Shopping Travel to the Traditional Market in Makassar City

The present study aims to analyze the travel behaviors of traditional market’s visitors in Makassar City, Indonesia, such as the visitor characteristics, trip chain, and the travel attributes of the visitors. In further, the present study models the trip intensity of the traditional market visitors using the multiple linear regression approach. The study carried out an interview survey on the visitors of Niaga Daya traditional market, one of the biggest traditional markets in the city. The interview survey based on a questionnaire sheet was conducted during the operation time of the market for two days, one day of weekday and one day of weekend. The analysis results show that the majority of the traditional market’s visitors are women and their profession as housewife. In addition, the trip chain of the visitors is dominated by the home-market-home pattern, and most of the visitors used a motorcycle. Furthermore, the results of the visitor intensity model to the traditional market show that the multiple linear regression model used is enough significant in the acceptance of the model. The model analysis revealed that the occupation, the household income, the travel distance, and the travel cost of the visitors have influenced significantly the visitor’s intensity in conducting the shopping travel to the traditional market. The study results provide an expectation in order to develop the continued travel behavior models such as the arrival time choice and the travel mode choice models of the visitors in further studies

The changing of oral argumentation process of grade XI students through Socratic dialogue

Arguments are one of the important purposes in the modern era of learning because it is the basic step to promote student’s critical thinking process and science literacy. Argumentation process can be trained through interactive dialogue that provides opportunities for students to argue. This research aims to change oral argumentation process in biology class of high school through the application of the Socratic Dialogue. The participants were students of grade XI science in one high school located in Surakarta, selected purposively. A classroom action research was done collaboratively between student teacher, lecturers, and teacher, follow the spiral cycles of research by Stephen Kemmis. During the implementation of research, the audio recorder has prepared to record the dialogue and arguments of the students. Next, data recorded that was converted to a dialogue transcript analyzed qualitatively using the Toulmin Argumentation Patterns (TAP). Another data source is teacher’s reflective diaries that contained notes during the learning process. The result shows that student’s oral argumentation process found were only claiming supported by weak warrants.
