Abstract

The aim of this research was to determine the effectiveness of guided inquiry based instructional materials in improving students’ mathematical communication ability. The subject of the research was 34 the students in class VIII7 of SMPN 12 Padang. The effectiveness was viewed from the students’ mathematics communication ability after learning by using guided inquiry based instructional materials. The communication skills of students are obtained from tests given in the form of essay tests with 6 items in the Pythagoras theorem lesson. I scoring rubrics indicators of mathematical communication ability were developed by referring to NCTM (1989) and Sumarmo (2003). The scoring results will be compared with the Minimum Completion Criteria (KKM) set by the school with a value of 75. There were 34 students taking essay tests. The value of students ≥ 75 as many as 24 people with a percentage of 70.5%, while the value of 10 other people < 75 with a percentage of 29.5%. More than 65% of students are above KKM. so that guided inquiry based instructional materials can improve students' mathematical communication ability

Abstract

The purpose of this research was to look at the tendency of students' perceptions of online learning in mathematics 2. This research is a quantitative research with survey method. The main data source of this research was obtained from the respondents. This research was carried out at Mechanical Engineering Study Program, faculty of engineering, Krisnadwipaya University, in June 2022. Data collection techniques using questionnaires. Respondent in this research were student of the 2nd semester of mechanical engineering study program in the 2021-2022 academic year. The measurement scale used is a Likert scale with a scale of strongly agree (SS), agree (s), disagree (TS), strongly disagree (STS). The data analysis technique used descriptive statistics. The average percentage of 76.08% for the aspect of online lecture facilities and infrastructure located in the area strongly agrees that the facilities and infrastructure are very supportive of carrying out online lectures. The percentage of 78.57% which is located in the regions strongly agrees with the online lecture aspect in the mathematics course 2. This means that online learning activities can run well and according to the RPS and have a positive impact on students in terms of critical thinking, innovation, expressing communication ideas, and utilization. technology.

Abstract

Precise, fast and accurate information regarding traffic density conditions is what toll road users need. Toll road users can choose a route that is faster, smoother and safer to pass through information on the traffic conditions of the toll road to be passed in front of them, which is conveyed from the Variable Message Sign (VMS). Given the very dynamic traffic conditions in Jabodetabek and Bandung, a very reliable media and information technology support is needed, so that it can provide information on real traffic conditions, precisely according to conditions in the field. This information can be retrieved from Google Maps periodically as needed to update information on traffic conditions in the segments that will be displayed on the VMS. The segment is usually the distance from gate 1 to the next gate, or Interchange 1 to the next Interchange. The period of retrieval of information via Google Maps depends on the dynamics of traffic conditions that will be displayed on the VMS. For example, information related to traffic conditions for the Tomang – Kebon Jeruk segment, which is very dynamic, requires a shorter period of change or information update than the Kunciran – Parigi or Kunciran – Serpong segments, the period of each information change is longer or infrequent, because the traffic conditions are still small. VMS will display the information generated through the distance and average travel time from 1 point to a certain point in 1 segment of the toll road which is processed so as to produce the average vehicle speed data which will be converted into text that will be displayed on the VMS. The text formatted information is sent to the VMS. The process of withdrawing Google Maps data to sending text to VMS can be done in less than 1 minute, even the process can be carried out for more than 1 VMS and even 10 VMS units in 1 minute. This results in fast and accurate information.
