Student Scientific Attitude Analysis TBLA-Based on Temperature and Health Materials

This research is a study that aims to foster students' scientific attitudes through lesson study based on transcript-based lesson analysis (TBLA). There are three main stages in this research, consisting of planning (plan), implementation (do), and reflection (see), which are carried out in 2 cycles. The study was conducted in November 2020. The research subjects were students of class VII Full Day Putri with 14 students. With scientific attitude parameters. It collects data in this study using video recordings of lessons, observation sheets, and documentation of other artifacts. In cycle 1, it can be seen that the results of the analysis of the scientific attitude observation sheet in students are still lacking; that is, most students only get a score of 1 on each indicator. Cycle 2 lesson study is intended to improve learning in process one so that revolution two is carried out based on process one reflection. The results of students' scientific attitudes in process two from the observation sheet analysis show several indicators of scientific attitudes for some students that can be improved. Still, some students decreased from cycle one; this was due to students who were less focused on learning. From the results of this study, it is suggested that teachers can apply the transcript-based lesson study based on lesson analysis. The application of technical analysis will enable teachers to increase their ability to make learning to be carried out more effectively.

Designing The Hypothetical Learning Trajectory (HLT) for Sinus Using Context of Scout Tent

One of the problems in modern mathematics learning is mathematical concepts presented by teachers to students such as machines. So, the concept is used by students as finished products without knowing the origin and how to reconstruct them. The effort that can be made by the teacher in overcoming this is by designing learning wherever possible starting with presenting realistic problems to arrive at an abstract idea. In this article we will discuss the design of sine rule learning in the context of scout tents, which is a type of design research. Design research has three cycles, namely preliminary design, classroom experiment, and retrospective analysis. In this article only the preliminary study phase will be discussed, which includes literature study activities, curriculum analysis, and the design early prototype. An HLT (Hypotetical Learning Trajectory) has been produced which deals with sine rules that use the context of scout tents.
