Abstract

This study aims to develop affective assessment instruments for practical assistants in physics laboratories. The development model used Plomp development model, consisting of five stages, namely: (1) the initial investigation stage; (2) Design; (3) Realization / construction stage; (4) testing, evaluation and revision; (5) implementation. The questionnaire is prepared based on theory and proven by its relevance (content validation) by experts. Collecting data in this study using non-test data collection techniques in the form of affective / attitude questionnaires. The affective score obtained will be analyzed the validity of the instrument construct using the analysis rash model theory with the winsteps program. Reliability using Alpha Cronbach. The attitude instrument was designed with reference to the criteria and indicators based on Rao's theory. Content validity by 7 experts showed that all items had good validity. The inter rater reliability of the questions was 0.8. Empirical validity shows that all items are valid. The instrument has item reliability 0.93 and person reliability 0.39 with good and moderate categories. This shows that the consistency of the answers from the subject is still weak, but the quality of the items in the instrument's reliability aspect is quite good. The instrument that has been developed meets the criteria of validity and reliability.

Abstract

This study aims to determine; (1) students 'metacognition abilities before being applied to guided inquiry-based student worksheets on Newton's Law II material, (2) students' metacognition abilities after being applied guided inquiry-based student worksheets on Newton's Law II material, and (3) how much influence is the application of guided inquiry based student worksheets on students' metacognitive abilities in Newton's Law II material in class X Mia SMA N 1 Marau. This research is a pre-experimental research design with one group pretest-posttest design research. The population in this study were all students of class X SMA N 1 Marau which consisted of 4 classes. The sample selected using a saturated sample, namely class X Mia as the experimental class. The results of the study were obtained before the treatment of the aspects of students' high metacognition abilities, namely the aspect of strategy setting ability of 81.81% and the aspect of the lowest metacognition ability, namely the aspect of metacognition ability of the debugging strategy by 0%. Meanwhile, the results after being given treatment for the students' high metacognition ability were the aspect of strategic setting ability of 95.23% and the lowest aspect of metacognition ability was the aspect of the metacognition ability of the debugging strategy of 57.77%. The result of the calculation of the effect size is 5.17 or 5.17> 0.8. Thus, the effect of the application of guided inquiry-based worksheets is very influential on students' metacognition abilities.

Abstract

This research aims to improve critical thinking skills by developing OASIS-based modules. The stages of the OASIS Model include concept orientation, concept analysis, concept synthesis, concept investigation and concept synergy. This type of research is development research. The subjects of the study were students of class X MIPA 1 of SMA Negeri 1 Jiwan, Madiun Regency. Data collection techniques were carried out by the method of tests, observations, and questionnaires. Data analysis techniques used the Likert scale and the Guttman scale for the questionnaire and t-test for the test method. Product validation based on 4 aspects namely linguistic, content eligibility, OASIS assessment and presentation of material for material experts and 3 aspects namely module size, cover design, and content design for media experts. Based on the validation results of the developed learning module material, an average rating of 69.6% can be obtained with reasonable criteria (with revisions) and media experts obtained an average rating of 80% with decent criteria. N-Gain results from pretest and posttest obtained an average of 0.35 so as to get a moderate criterion (the ability to think critically increases). Thus the learning modules that have been developed are worthy of being used as teaching materials in learning physics in the Temperature and Heat material and can improve students' critical thinking skills.

Abstract

The aims of this study to (1) determine the student ability of critical think and analyze, using the bahtsul masail method, (2) to find out the difference between the bahtsul masail method and the conventional method in physics learning. The method in this study using a true experimental quantitative method with a pretest-posttest control group design. The population used was all class XI students of SMA NU Al-Ma'ruf Kudus and samples were students of class XI MIPA 2 and MIPA 4 taken by random sampling techniques. The data collection used the pretest and posttest to determine the effect of the bahtsul masail method. The results shows (1) The student thinking ability using the Bahtsul Masail method get higher results. (2) Based on the results of data analysis using paired t-test, it is obtained tcount of -7.4828 and ttable of 1.67 with a significance level of 5% and degrees of freedom of 58 so that if t <ttable, then Ho is rejected and Ha is accepted; This means that there is a difference between the mean pretest and posttest scores, there is also a positive and significant relationship between the bahtsul masail model with students' critical thinking and analyzing abilities. The N-gain value is obtained by an average N-gain score of 0.5902 in the medium category. And for the N-gain score obtained an average of 59,023 which is categorized as quite effective. Thus the application of the bahtsul masail method is effective enough to be applied in a lesson.

Abstract

This research aims to improve the motivation and results of learning physics effort competency, energy, and power through learning with a scientific approach for students of grade X TKRO 4 SMK Negeri 2 Wonosobo. The data collection techniques used documentation and observation techniques to process the data of observation instruments. The results showed that based on theorists through study with scientific approaches can improve the motivation of learning physics for students. Based on empirical (research), the internal motivation aspect rises by 3.48% and the external motivation aspect rises by 3.01%. Then through learning with scientific approaches can increase the motivation to learn the physics effort competence in energy and power subject matter. Then by theoretical, that through learning with scientific approaches can improve student learning results. While based on empirical (research), apparently the highest value remains 86.67, the lowest value rises 37.06%, the average value rises 35.14% and the number of students who graduated up 41.67%, then through learning with scientific approaches can improve the results of the study of Physics effort competence, energy, and power for students. Therefore through learning with a scientific approach can improve the motivation and results of the physics learning of effort competence, energy, and power for students in grades X TKRO 4 SMK Negeri 2 Wonosobo Semester 2 years lesson 2019/2020. Findings in this study reinforce theoretical and empirical perspectives, in the teacher's effort to achieve optimal learning results.
