摘要：This study aims to examine students' reasoning based on the model in each
laboratory work style and find the effect on scientific attitude and student activity.
This study uses a quantitative approach with the experimental method. The study
was conducted in three classes with different lab work styles. Arduino and sensors
were used as a measurement apparatus in Ohm's law experiments that will
stimulate students' reasoning in each lab work. The measuring instruments consist
of a scientific attitude scale, observation sheet, and worksheet. A descriptive
statistical analysis was used to describe students' reasoning in the three laboratory
work styles. The improvement of scientific attitude and activities were analyzed by
normalized gain. The effects of the three types of lab work to scientific attitudes
were analyzed by analysis of variance (ANOVA). The results show that the style of
lab work gives rise to various students' reasoning. Observations show that many
students solve problems in the experiment by reasoning to improve the
measurement model. Problem-solving laboratory work is effective to improve
activities and scientific attitudes. This study has succeeded to discover alternative
concepts in the laboratory work with reasoning based on models.
