Abstract

Problems in learning evaluation such as Paper Based Testing (PBT) and Computer Based Testing (CBT) which ignore the ability of individual variations cause the information obtained to be less than optimal. Experts have developed a learning evaluation tool, namely the Computerized Adaptive Test (CAT) to overcome these problems. In the CAT system, the items given to test takers are adjusted to the test taker's ability level. The purpose of this study was to determine the characteristics of the CAT evaluation tool on the topic of vibration, wave and sound as well as to be able to determine the profile of student learning outcomes in vibration, wave and sound materials using CAT evaluation tools. This study uses the Research and Development (R&D) method with a 4-D development model, namely define, design, develop and disseminate. The CAT developed is website-based and has a 78 item question bank with the topic of vibration, waves and sound. The result of the development obtained is that the validity of the instrument gets Aiken's V validity score with an average of 0.93 which exceeds the minimum validity of 0.87 and is declared valid. The validity of the media expert got a score of 86% in the very good category. The method of question analysis uses the Item Response Theory (IRT) one-parameter logistic model (1 PL). The level of difficulty of the questions obtained is easy category as many as 17 items, medium as many as 30 items and difficult as many as 31 items. The results showed that the feasibility of CAT media was 74% in a good category. Obtained profiles of student learning outcomes material vibration waves and sound using CAT with an average value of 47.91 categorized as being slightly below the average of the maximum value of 100.The ability level of test takers can be estimated with only 11-23 items resulting in efficiency better time than PBT and CBT. There is a relationship between the score using CAT and the score without using CAT positively with a correlation value rcount of 0.600192, this value can be interpreted as a strong level of relationship, if the score without CAT is high then the score obtained with CAT is also high, and vice versa.

Abstract

This study aims to describe the procedural thinking ability of prospective teachers to develop physics experiment procedures. This research is descriptive qualitative. Samples were selected by purposive sampling techniques, namely 4th semester and 6th semester students who have attended Basic Physics 1 courses and Basic Physics Experiment 1. The subjects of this study consisted of six people, who were selected based on the ability to compose experimental procedures of physics. Researchers as the main instrument in the study are supported by the results of written tests, interview results and field notes. The results showed that procedural thinking skills in prospective teachers for type-3 (low ability group ) and type-2 (medium ability group) were able to arrange experimental procedures systematically but less detailedly, while in prospective teacher students for type-1 (high ability group) were able to arrange experimental procedures systematically, logically and in detail. The difficulties faced in arranging physics experimental procedures are lack of conceptual understanding, less experimental activities, and prospective teacher students lack of practice in designing physics experimental procedures.

Abstract

Higher Order Thinking Skills (HOTS) is higher-order thinking skills with higher thinking than memorizing facts or retelling something that is heard. In Higher Order Thinking Skills (HOTS) there are three categories: (1) transfer, (2) critical thinking, and (3) problem solving. In this study, the focus is on the third category, physics problem solving ability of students. The main analysis in developing the assessment is the value of validity, reliability, distinguishing power, and the level of difficulty of the questions. This study used a one shot case study method. Based on the results of the validity test using the help of software IBM SPSS Statistic Data Editor 22, the results of the questions are valid with R results> R Table. The value of R in the reliability test is 0.931. In the reliability test obtained, namely R results> R Table to get reliable test results. The difficulty level of questions with category 6 is good and 9 is very good. The distinguishing power of questions with category 3 difficult questions, 9 medium questions, and 3 easy questions. Newton's Law Assessment obtained valid and reliable questions that are used to measure the ability to solve physics problems.

Abstract

Teaching material is a learning resource that can help teachers to teach students in the classroom. Teaching materials used in several schools still use black and white images. The magazine has a variety of text views along with images combined with attractive colors. The materials contained in the teaching material also still emphasizes the description of the material rather than the application and has not linked the Islamic values listed in KI-1 in the 2013 curriculum. I-SETS-based learning approach (Islamic, Science, Environment, Technology, Society) is a contextual approach that links elements of Islam, science, environment, technology, and society. Magazine-based physics teaching material also contain a charge of character values proclaimed by the government. The purpose of this research are to compile a magazine-based physics teaching material, to determine the feasibility, readability, and practicality, as well as character development. The method used in this research is Research and Development. The results showed that magazine-based physics teaching material were compiled using several characteristics, the results of the feasibility test in terms of aspects of content, presentation, language, and graphics of teaching material were very feasible to use. Readability test results show that the teaching material is easy to read. The practicality test results show that teaching material were practical used by students. The development of religious character, discipline, responsibility, and communicative increased after using magazine-based physics teaching material.

Abstract

Diffraction is one of the properties of light in the form of a bending event in the direction of the propagation of the waves through a narrow gap. Research on natural materials as an alternative to grating has been carried out with varying results. Natural ingredients in the form of scallion stems (Allium fistulosum) and banana heart (Musa paradisiaca) were chosen as the diffraction lattice preparations because they have fibers that resemble scratches on the diffraction grating produced by factories. Special care is given to each preparation to obtain the fiber. By using Tracker and analysis of the level of accuracy, the results obtained value m, and an accuracy of 95.81% for the diffraction grating of scallion stems, and the value of d = and accuracy of 90.01%. The results of this study indicate that scallion stalks and banana blossoms have potential and can be used as diffraction grating to explain light diffraction phenomena.

Abstract

In the 21st century education and technology are developing more rapidly. This requires each individual to have skills. One of the skills that must be possessed is creativity. According to Munandar creativity is devided into four models namely person, process, press and product. Product creativity according to Peter Nilsson can be assessed in terms of product form and product Quality based on theory of village Taxonomy Design Creativity Peter Nilsson product form is devided into five aspects, namely Imitation, Variation, Combination, Transformation, and New Creation. This research focuses on transformation aspects only, conducted on Physics Education college students who have received analog electronics courses, then college students are asked to design the opening and closing tools of the water tap according to the order sheet, to then be assessed with an instrument that has been validated by an expert lecturer. The data analysis technique uses a descriptive quantitative approach. The results of the data analysis concluded that the level of creativity of physics education college students in designing the product aspects of transformation, 5,1 on a scale of 0-7 which means college students of UNNES physics education have a high level of creativity.
