The objectives of this study are: (1) to know the need of teaching materials for the senior high school teachers and the students, (2) to know the procedures of Biology teaching materials development of contextual teaching learning-based teaching, (3) to develop Biology teaching materials of contextual teaching learning-based teaching. The research method of this study is research and development. This study found: firstly, the need of teaching materials for the senior high school teachers and the students considers some elements, they are a) situational context, b) fits to curriculum, c) exercises/tasks enable to activate the students' achievement, d) practical based implementation, and e) interesting, clear, and easy to understand. Secondly, the model of development is adapted from Borg and Gall, they are: data collection, planning, drafting a model, experimenting the model, revision the draft, field experiment, revising the final draft, and implementation. Thirdly, the score of post test shows 66.9 (control class) and 79.6 (experimental class), t-value of f value is 2.67 > 1.67 of f table. It can be concluded that the use of Biology CTL based-teaching materials enables to improve the students' achievement in learning Biology.
Augmented Reality is a study that is now popular. Many researches theme have been published in various reputable journals. The purpose of this study is to provide an overview and visualization of Augmented Reality which is used as a medium of learning. This research is a qualitative research through descriptive analysis with literature review formed in bibliometric analysis which describes and visualizes ongoing phenomena as well as in the past regarding various topics related to Augmented Reality. Through the Scopus database source, there are 882 documents related to Augmented Reality were obtained from 2016 to 2020 and various data related to the number of documents by country, author, subject area, visualization of relationships between topics. Topics that are categorized as rare or have not been associated with AR will be an option for us to study more deeply so that it will give knowledge to the scientific of AR as a medium for student learning.
This research aims to examine the effect of Project-based Collaborative Learning (PBCL) strategy on conceptual understanding and application of biology for students with different social skills. The research design used a quasi-experimental design of a non-equivalent control group. The population in this study was all 11thgrade students at Al-Abidin Surakarta high school. Seventy-five students were taken as the research subjects and divided into two groups, 38 students in the experimental class with PBCL implementation and 37 ones in the control class with Collaborative Learning (CL) strategically. Sampling technique using cluster random sampling. The instruments used a questionnaire of social skills developed by Tapia-Gutierrez & Delgado (2015) and a test instrument of multiple choice and essay for conceptual understanding and concept application. The data were analyzed using Multivariate Analysis Of Variance. Based on the results of the research, all significance values 0.00<0.05. The result shows that a significant difference in both strategies PBCL & CL towards either conceptual understanding or concept application exists. In addition, a significant difference in social skills towards either conceptual understanding or concept application appears. The interaction effect between those strategies and social skills towards conceptual understanding and concept application was found.
Abstrak.Sistem pengajaran Indonesia masih dilakukan secara manual dengan menggunakan media yang konvensional seperti kertas (buku) dan papan tulis. Berdasarkan kenyataan ini, maka timbul suatu gagasan untuk membuat suatu aplikasi pembelajaran matematika SMP (Sekolah Menengah Pertama) untuk bekal menghadapi UAN (Ujian Akhir Nasional) berbasis android. Tujuan penelitian pengembangan ini yaitu mengembangkan aplikasi pembelajaran biologi smp berbasis android untuk bekal menghadapi UAN di SMP Islam Bakti 1 Surakarta. Pengembangan media pembelajaran ini, dilakukan dalam bebarapa tahap. Model pengembangan yang digunakan mengacu pada model pengembangan ADDIE yaitu analysis, design, development, implementation dan evaluation. Hasil pengembangan berupa aplikasi Android yang memuat materi biologi SMP.Setelah dilakukan penelitian melalui tahap-tahap tersebut, maka diperoleh hasil penelitian berupa media pembelajaran berbasis android untuk mata pelajaran biologi yang bisa dijadikan salah satu alternatif bagi siswa SMP dalam mempelajari biologi SMP.Kata kunci : Biologi, android, UAN, pembelajaran.
Biology learning is highly recommended to be presented contextually following daily experience and phenomena. This study, a quasi-experimental research using a pretest-posttest non-equivalent control group design, aimed to understand the effect of project-based collaborative learning towards the concept mastery of mushrooms. The subjects of the study were 75 tenth grade of high school students in Surakarta City, Indonesia, divided into two classes: 38 students in the experimental class 37 in the control class. In the experimental class, the students were treated with project-based collaborative learning strategies. In project-based collaborative learning strategy, students were challenged to create a project on oyster mushroom cultivation (Pleurotus ostreatus) With the media garden waste such as sawdust. In the control class, the students were treated with direct instruction. The instrument used was a multiple-choice test and essay developed by researchers to measure students' concept mastery towards mushrooms. Research data were analyzed by independent sample t-test. The results found that the average n-gain score for the experimental and the control classes were 63.09% and 45.73%, respectively. Moreover, all indicators of mushroom concept mastery showed the n-gain scores for the experimental class higher than the control class. Analysis of independent sample t-test proved that the significant differences existed between direct instruction and project-based collaborative learning in improving the concept mastery of mushroom. Finally, This research concluded that project-based collaborative learning is more effective in enriching the concept mastery than direct instruction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
