Abstract

This study aims to determine: 1) Knowing the characteristics of the product development model of PAKDE lecture based on a scientific approach; 2) Knowing the effectiveness of the application of the PAKDE lecture model based on a scientific approach in improving student learning achievement; and 3) Knowing the effectiveness of the application of the PAKDE lecture model based on a scientific approach in improving the scientific attitude of students. The procedure in this study adapts the development of a 4-D model device developed by Thiagarajan. Field trials using the Wave class with a pretest posttest control group design. Data collection techniques used validation sheets for feasibility data, observation sheets for implementation data, and multiple choice tests for learning achievement data in the cognitive domain of students and questionnaires for data on students' scientific attitudes. The data analysis technique used descriptive statistics to determine the characteristics of the PAKDE lecture model based on a scientific approach, the n-gain score test to determine the increase in learning achievement and the t test to determine the difference in average cognitive learning achievement. The results showed that: 1) The characteristics of the PAKDE lecture model based on the scientific approach that was developed were concluded to be very good; 2) The application of the PAKDE lecture model based on a scientific approach is effective in improving student learning achievement; 3) The application of the PAKDE lecture model based on a scientific approach is effective in improving the scientific attitude of students.

Abstract

This study aims to produce interactive physics learning media based on macromedia flash 8 straight motion material for Class VII students of SMP/MTs. This type of research uses the Research and Development (R&D) approach by adopting the ADDIE development model (Analyse, Design, Development, Implementation, and Evaluation). The design of learning media trials uses the Post-Test Only Control Group Design. The data collection instruments were material expert evaluation questionnaires, media expert evaluation questionnaires, science subject teacher evaluation questionnaires, student response questionnaires, multiple choice tests and student learning activity questionnaires. Data collection techniques were test techniques and observation techniques. Data analysis techniques are media feasibility test, normality test, variance homogeneity test and hypothesis testing. The results of the study from the aspect of the feasibility of learning media, media experts stated that it was feasible with an actual score of 75, material experts stated that it was feasible with an actual score of 73, teachers of science subjects stated that it was feasible with an actual score of 66, and the average response score of 4 students was 58.25 . While the research results from the aspect of learning media trials show that interactive physics learning media based on Macromedia Flash 8 is effective on student learning outcomes with an average experimental class score of 70.38 and classical learning mastery of 71.42%. The percentage of active students is in the good category with a percentage of 69.09%. When compared with the control class with an average value of 50.37 and 22.22% classical learning completeness. The percentage of active students falls into the moderate category with a percentage of 41.82%.

Abstract

This research aims to find out the specifications of the product resulting from development, the feasibility, and effectiveness of the scientific approach-based pocket book learning media on measurement material. This research falls under the category of  research and development (R&D). The method employed in this research was the 4-D method, consisting of the stages of define, design, development, and dissemination. The feasibility level was obtained from the scores given by expert validators and subject teachers, and the 10th-grade students of SPM Ulya Irhamna Bil Qur'an as respondents. The validation from the content expert received a score of 4.13, the validation from the media expert received a score of 4.01, the validation from the subject teacher received a score of 4.09, and student responses yielded a score of 4.18. The research results indicate that the media is suitable for further development. The level of effectiveness was elaborated in the form of pre-test and post-test. The average score obtained from the pretest was 62.5, while the average score obtained from the posttest was 78.9. The categorization of the score based on the N-gain score falls within the range of  0.3 ≤ g ≤ 0.7, categorizing it as moderate effectiveness. Therefore, the interpretation of the N-gain effectiveness score falls within the 40 – 50 percentage range, categorizing it as less effective
