<![CDATA[The purpose of this study was to improve the achievement of IPAS learning outcomes of fourth grade students of SD 3 Wergu Wetan through the implementation of the Think Pair Share Learning Model Assisted by Lapbook Media. The Think Pair Share Model is used because it is considered to be able to encourage student collaboration and discussion, while Lapbook Media has the potential to present IPAS material visually, interactively, and easily understood, which is relevant to the characteristics of fourth grade students. This study is included in the type of Classroom Action Research (CAR) which is carried out in two cycles. Each cycle consists of four stages, namely planning, implementation, observation, and reflection. The subjects in this study were 23 fourth grade students of SD 3 Wergu Wetan. The results of the study revealed that the use of the Think Pair Share learning model with the help of lapbook media was proven to significantly improve the learning outcomes of fourth grade students in science. There was a progressive increase in the level of student learning completion, starting from 22% in the pre-cycle stage, increasing to 48% after cycle I, and reaching 83% in cycle II. This increase was supported by an increase in the average class score from 62 in the pre-cycle stage, the score increased to 72 in cycle I, and reached the highest score of 83 in cycle II, as well as improvements in the distribution of student scores as a whole. This study concludes that the use of the Think Pair Share learning model assisted by Lapbook media is an efficient and promising approach to improving students' academic outcomes in science lessons in elementary schools. Therefore, this model and media are recommended as an alternative teaching strategy that is innovative, fun, and able to activate student involvement more optimally.]]>
