The aim of this research is to describe validity flipbook type e-book in terms of the feasibility content, language, and display; and describe the practicality of an e-book in terms of an implementation observation. The method used in this study is a modified research and development method and was carried out at the Postgraduate Science Education, the State University of Surabaya in February 2020 - August 2021. The data collection technique was carried out using the validation method and the implementation observation method. The assessment instrument uses a validation sheet and an implementation observation sheet. The validity of the flipbook type e-book is reviewed from the feasibility of the content, the feasibility of the language, and the feasibility of the display. The validity of the flipbook-type e-book was assessed by three validators which included two biology lecturers and one biology teacher. For practicality, use the implementation observation sheet in terms of the use of flipbooks during the learning process. The observation sheet contains statements that will be filled out by four observers. Data analysis was carried out quantitatively. The developed e-book was tested on 20 students of class X Senior High School students in August 2021. The validation results of the flipbook type e-book by three validators obtained an average score of 3.84 with a very valid category. Based on practicality in terms of implementation, flipbooks get an average percentage of 87.2%. Thus, the flipbook-type e-book on the identification of Basidiomycota fungi is declared valid and practical.

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.

 The main purpose of this research was to know the level of understanding of students’ concepts in the sound wave and light waves material in class XI students of senior high school in the sub-district of Tampan, Pekanbaru. This research is survey research. The population in this research were all students of class XI of state Senior high schools in the Tampan sub-district of Pekanbaru, while the research sample numbered 65 students. The research instrument was in the form of concept understanding tests that were compiled based on indicators understanding the concepts of translation, interpretation, and extrapolation. The questions used were in the form of a written test in the form of multiple-choice totaling 26 items. The results of the answers to the questions given are then analyzed using descriptive analysis. The results of this research provide information, that the level of concepts understanding of class XI students in high schools throughout the sub-district of Tampan, Pekanbaru in physics lessons on sound wave material and light waves are in the very low category for the three indicators of translation, interpretation, and extrapolation. Therefore, a learning strategy is needed that is able to overcome the low understanding of the student's concepts.

This research aims to identify class XI MIPA1 senior high school students, who experience misconceptions on the kinetic theory of gas. The method used to determine students who experience misconceptions is the Certainty Response Index (IRK) method. This method has four indexes in identifying students' mastery of concepts, namely lucky guess (LG), not knowing concept (NKC/TTK), knowing concept (KC/TK), and misconception (M). The subjects of the study were senior high school students in class XI MIPA1 in Tasik Malaya. The research instrument used was a kinetic theory of gas test equipped with an IRK scale assessment instrument. This research is a quantitative descriptive research that can determine weaknesses in understanding students' physics concepts with the IRK method. The results of data analysis using IRK revealed that students who experienced lucky guess (LG) were 9.0%, students who knew the concept (TK) were 35.2%, students who lacked knowledge or did not know the concept (TTK) were 21.9%, and students experiencing misconceptions (M) of 33.8%. Based on the sub-topic analysis, the level of misconception the results are also in the high category. Thus it was concluded that through the IRK method it was identified that most students were still experiencing misconceptions, did not know the concepts, and were lucky guessed in understanding the kinetic theory of gas in the class XI MIPA1 of senior high school in Tasik Malaya.

Physics misunderstandings still occur in high school students now. Therefore, it requires complete learning so that students' conceptual physics can be stable and embedded in everyone. This study aimed to diagnose the extent to which students' conceptual understanding of physics on the topic of static fluid is. This study used a survey approach to form a written test for 100 senior high schools in two schools in Central Maluku Regency. The results showed that there were still many students who experienced fluid misconceptions in cases 2, 3, and 5 to achieve a good level. Therefore, deep learning is needed so that students' conceptual physics will be good and not forgotten

Metabolic Fuel

In the present work, I investigated the origin of the misconception that glucose is the sole metabolic fuel previously described among Brazilian high school students. The results of a multiple-choice test composed of 24 questions about a broad range of biology subjects were analyzed. The test was part of a contest and was answered by a sample composed of undergraduate students as well as biologists and practicing biology teachers. The majority of the responders had difficulties in recognizing the existence of gluconeogenesis and the possibility of ATP production using other fuels other than carbohydrates. Biology teachers and biologists seemed to either lack the knowledge or present the misconception regarding energy-yielding metabolism found among students. I argue that in both cases, biology teachers are likely to teach metabolism-related subjects in a manner that may contribute to the appearance of the misconception among high school students.
