An electronic module was one of the teaching materials. This study aimed to see the feasibility of the electronic module material for thecirculatory system. We used the research and development method. This study’s method had steps that included potential and problems, data collection, product design, design validation, design revision, and product testing. Five validators validated product design. The data analysis used the CVR and CVI values for each criterion in the validation aspect which are course, graphic, contents, and language with a minimum value of 0.99. The study found two important findings. First, from the validator, the CVR values in all elements had a value of 1, and the CVI results each had a value of 1. Hence, the electronic module of the circulatory system material is declared valid and feasible to use. Second, the product trial obtained an overall average score of 88.4% and was very positive. It means that the electronic module could be an alternative teaching material used in the learning process at school or self-study for the student at home.","PeriodicalId":33764,"journal":{"name":"Jurnal Mangifera Edu","volume":"166 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80466398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to determine the urgency of providing life-long learning for students in biology learning. The research method uses qualitative methods, the research instrument used in this study is a questionnaire. The results showed that the student's response was in the high category with a percentage of 60%, which means that students already understand the concept of life-long learning but have not applied it in their daily lives. 60.9% of students responded that life-long learning had not been implemented in biology learning at school and agreed if it was applied in biology learning.

From the results of the initial needs analysis of class X questions, science process skills are still low, the teacher has not fully developed the science process skills-based assessment because it still uses questions from biology books. This study aims to determine the characteristics and feasibility of assessment based on science process skills developed in biology class X semester 2. This research is development research. Development is carried out using a procedural model by adapting Mcintire's research and development model, with 4 stages of test development including defining competencies, test participants and test objectives, developing test plans, compiling test items, writing administrative instructions. This research stage is limited because it only wants to know the characteristics and feasibility of the assessment. The research instrument used an interview sheet, a questionnaire sheet, and an observation sheet. Expert validation was carried out by 6 expert validators: (1) material experts; (2) linguists; and (3) evaluation experts; The data analysis technique uses qualitative descriptive that refers to the formula adapted by Sugiyono (2018) with a scale of 4. The results of this study are in the form of a biological assessment based on science process skills in the form of multiple-choice questions in which there is biology material for class X semester 2.
