This study aims to describe the improvement of student learning outcomes in science learning using the Problem Based Learning (PBL) Model in Class V of SDN 16 Pulau Karam, Pesisir Selatan Regency. This study is a classroom action research (PTK) with a qualitative and quantitative approach. Implemented in 2 cycles, cycle I consists of 2 meetings and cycle II consists of 1 meeting. The results of the study showed an increase in teaching modules in science learning using the Problem Based Learning (PBL) model, the implementation of science learning using the Problem Based Learning (PBL) model and student learning outcomes in science learning using the Problem Based Learning (PBL) model. This can be seen from the average observation results of the Teaching Module cycle I which was 87.4% (B) increasing in cycle II to 92.8% (SB). This is also seen in the average results of teacher activities in cycle I which were 85.9% (B) increasing in cycle II to 93.8% (SB). In student activities, the average cycle I was 84.3% (B) increasing in cycle II to 93.8%. In student learning outcomes, the average cycle 1 was 81% (B) and increased in cycle 2 to 91%. Based on these results, it can be concluded that using the Problem Based Learning (PBL) model can improve the results of learning science in class V SDN 16 Pulau Karam, Pesisir Selatan Regency.

The purpose of this study was to compare see students' ability to read fluently at level 3 and to see their ability to explain reading content in terms of students' opinions/perceptions through dialogue texts. This research uses a qualitative approach, with a qualitative descriptive type of research. Data collection techniques in this research consisted of: (1) assessment of level 3 fluent reading abilities (2) interviews with students regarding their perceptions regarding the dialogue texts they read (3) documenting the process of reading the text. . Based on these data collection techniques, the research instruments used consisted of: (1) level 3 fluency reading ability assessment sheet, (2) reading comprehension assessment sheet (3) documentation of students' reading processes. This research was conducted by Mifta Hurrahmi and Wini Media Putri, where the research subjects were elementary school students. The results obtained are based on students' ability to read and explain the contents of the reading from the interviews that have been conducted. It can be concluded that the use of dialogue texts is more effective in determining the level of students' ability to read fluently at level 3 and helping students understand the content of the reading they read
