This study aims at analyzing the effect of the Virtual Instrument System Laboratory (Vis-Lab) to enhance technological literacy and problem-solving skills among junior high school students. This type of research can be categorized as Quasi-experimental research with Nonequivalent Control Group Design. The subjects of this study were the seventh-grade students in one of the junior high schools in Sleman Regency, Yogyakarta. The research instrument consisted of pretest and posttest on technological literacy and problem-solving skills. The data analysis technique used N-Gain analysis, prerequisite test, hypothesis testing with MANOVA, and effect size. Based on the MANOVA test, the Sig. value of 0,000 <α (0.05) indicated that there was a gap in the students’ technological literacy and problem-solving skills between the control and the experimental class. The use of VIS-Lab learning media enhanced the ability of technological literacy by 9.0% for the experimental class and 2.1% for the control class respectively. Meanwhile, the effective contribution to the use of VIS-Lab learning media was 36.5% for the experimental class and 4.73% for the control class. It means that the use of VIS-Lab learning media contribute effectively to improving the ability of technological literacy and problem-solving.

Physics Problems

This research is a descriptive study with a qualitative approach, which aims to describe the ability of junior high school students to solve physics problems in various forms of problem representation. The subjects in this study were the IX grade junior high school students in six Palu city schools. Respondents for interviews in the study amounted to 4 people for each form of problem representation, with the criteria of students who answered right, students who answered ± 50% correct, students who answered incorrectly, and who did not answer. The instrument used was a test of problem solving skills and interviews. The data obtained were analyzed qualitatively including data reduction, presenting data and verification while descriptive analysis was performed by calculating the total score, calculating the percentage and categorizing problem solving abilities. The results obtained by the average ability of junior high school students to solve physics problems in various forms of problem representation 21.86% (less category), with the percentage of each form of representation ie verbal representation 36.09% (less category), image/picture representation 23.78% (less category), diagram representation 19.47% (poor category) and graphic representation 8.10% (poor category).

Problem Description

The purpose of this study was to analyze the problem solving skills of junior high school students based on student gender. This research is descriptive qualitative. Data from the research results obtained from the results of writing written questions and the results of oral interviews of 14 students of class VIII from Waringin Middle School, Bandung. The instrument used is 3 numbers of material questions that are in accordance with indicators of cognitive aspects. The results of this study indicate that from the problem description given and from the results of interviews about problem solving abilities of junior high school students with female gender on average, it is better than the problem solving ability on average junior high school students have a way to solve while solving problems. So that researchers can conduct research using active student learning methods to get better results, and also be able to understand other factors related to problem solving problems of junior high school students, both male and female students.

Problem Solving Skills

This research aims to describe the mathematical problem solving skills of junior high school students in relationship materials and functions with Polya strategy. The method used in research is a qualitative descriptive method. This research was conducted at SMP Negeri 35 Palembang with a class XI.6 research sample of 30 people. The research subjects were taken by 6 students, who were grouped into three categories, namely high, medium and low who were taken 2 people each from each category.. The data collection techniques in this study are tests, interviews and documentation. The results of the data obtained are then analyzed using data reduction analysis techniques, data presentation and verification. So the results of the study show that: 1) students who have high category problem solving skills are able to carry out all stages of problem solving, 2) students who have problem solving skills category are able to carry out the problem solving stages of the problem, but at the stage of carrying out planning and problem solving students make mistakes in operation and are not able to perform the stage of planning the answer correctly, 3) students who have low category problem solving skills are only able to carry out one stage that is understanding the problem and not being able to carry out the stage of planning the solving strategy planning and troubleshooting and re-examining the answers obtained correctly.

Problem Solving Skills

This research is motivated by the low ability of problem solving skills of junior high school students. So that a learning model needed that can enhance this ability. The CORE model with open ended approach is believed to be able to improve problem solving skills in junior high school students. The research was conducted in Junior High School 8 Serang 2018/2019 academic year which aim to see the influence of CORE model with open ended approach on problem solving skills of junior high school students. The research method used in this study is quasi-experimental with the type of design that is the nonequivalent pretest posttest control group design. This studi involved two classes consisting of the experimental class and the control class. The population in this study were all students of class grade VII of Junior High School 8 Serang. The sample of this tudy was the VII A class as experimental class and VII B class as control class. The instrumen used in this study was a mathematical problem solving test instrument. The result of the study provide the conclution that there is an influence of CORE model with open ended approach on problem solving.
