This preliminary study aims at developing a program to improve teacher candidate students’ conceptions on the topic of states of matter and their changes by using Predict-Observe-Explain (POE) strategy. This study employs pre-experimental method. The subjects involved were third-semester students of a primary school teacher education study program (Pendidikan Guru Sekolah Dasar PGSD) in a university in West Java, Academic Year 2017/2018. The research instrument was a five-tiered diagnostic test in the form of multiple-choice. The instrument had gone through expert and empirical validation processes, which were provided before and after the implementation of the POE strategy. The data obtained were analyzed through descriptive and inferential statistics (t-test). The results showed that the use of POE strategy was able to improve the students’ comprehension on the concept of states of matter and their changes either at macroscopic level (N-gain 0.32, p=0.00), submicroscopic level (verbal N-gain 0.44; p=0.00, and visual Ngain 0.49; p=0.00), or symbolic level (N-gain 0.41; p= 0.00). The acquired N-gain indicated the need for further research to improve the course program of states of matter and their changes using the POE strategy to obtain higher N-gain that indicates the need for improvement of the program, including the processes and aids of the course.

未来小学教师对物质状态的观念转变及其通过预测-观察-解释策略的变化

本初步研究旨在开发一个程序,通过使用预测-观察-解释 (POE) 策略来改善教师候选人对物质状态及其变化主题的概念。本研究采用预实验方法。所涉及的科目是西爪哇一所大学的小学教师教育学习计划 (Pendidikan Guru Sekolah Dasar PGSD) 的第三学期学生,2017/2018 学年。研究工具是多项选择形式的五级诊断测试。该工具经过了专家和经验验证过程,这些过程在 POE 战略实施之前和之后提供。获得的数据通过描述性和推论性统计(t 检验)进行分析。结果表明,无论是宏观层面(N-gain 0.32,p=0.00)还是亚微观层面(语言N-gain 0.44),POE策略的使用都能提高学生对物质状态概念及其变化的理解。 ;p=0.00,和视觉 Ngain 0.49;p=0.00),或符号级别(N-gain 0.41;p=0.00)。获得的 N-gain 表明需要进一步研究以改进物质状态及其变化的过程程序,使用 POE 策略以获得更高的 N-gain,表明需要改进程序,包括过程和辅助课程。
