Background and objective: Problems currently occurred in the environment are caused by a lack of environmental awareness of the community. Biology students learn the environment in ecological learning. Students must explore environmental knowledge (EK) and are expected to have high environmental awareness (EA) and then apply their knowledge in daily life with pro-environmental behavior (PEB). There is a need for designing climate-change book serials for university students (CCBS-US) towards contextualized learning. This study aimed to determine the relationship between EK and EA and the PEB of biology students as a baseline for designing CCBS-US. Methods: The study used a quantitative descriptive method with a correlational design. Total 136 biology students from a state university in Jakarta, Indonesia served as samples of the study. Results: Research results revealed a positive relationship between EK and PEB of biology students. There was a positive relationship between EA and PEB of biology students and between EK and EA and PEB of Biology students. Moreover, 77% of students reported their EK is very high, 55% of students reported their EA is medium, and 46% of students reported their PEB is medium. Ecological learning has a vital role in shaping the EK, EA, and PEB, thus CCBS-US needs to be developed. Conclusion: The study concluded that there was a relationship between EK, EA, and PEB. The study recommends the development of CCBS-US based on the survey results.

The ethical issue is one of the most important themes in both science and environmental education. Especially related to the right of other species, animal dissection has been brought about two contradictory attitudes. In spring 1996, a survey was conducted to assess the status of animal dissection in secondary schools and the awareness of 94 biology teachers and 422 secondary students toward animal dissection. And the meaning of animal dissection in biology class was discussed in terms of environmental education. The findings were as follows: First, most of students(96.6%) had participated once or twice to animal dissection experiments(eg. fish, frog, shellfish, cuttlefish and chicken). And about half of teachers (57.4$\sim$64.9%) and some students(41.9%) felt ethical conflict in animal dissection. Second, many teachers(81.0%) and students(87.1%) thought that animal dissection was effective method to achieve the goal of biology education, but they needed more consideration on the respect for life in animal dissection experiment. Third, many teachers(88.3%) had students, who objected to animal dissection, participate obligatorily or passively. Fourth, teachers and students thought that audio-visual media such as video(teachers 63.5%, students 39.7%), computer simulations(teachers 31.7%, students 28.1%) and models(teachers 22.2%, students 24.1%) could be effective as alternatives. These findings suggest that animal dissection experiment, although it is needed to achieve the goal of biology education, requires careful consideration on the rights of animal and the respect for life, and alternatives for students who object to animal dissection in biology class.

This study analyzed the effects of 'online biology learning using E-learning system' on elementary school students' science-related attitudes. Samples of the study were composed of 95 sixth-grade students of N elementary school in Seoul, Korea. The learning was conducted for 11 times over a month. The main results of this study are as follows. First, for the paired t-test, a statistically significant difference between the pre and post scores of science-related attitudes was found. After conducting the online biology learning science related attitudes scores of students generally declined. "The boredom caused by simply watching online biology contents" is the decisive cause of the decline in science-related attitude scores analyzed through interviews. Second, in ANCOVA, according to 'levels of meta-cognition'. there was no statistically significant difference in scores of science-related attitudes. but, there was statistically significant difference in science-related attitudes according to 'adoption of scientific attitudes'. Students of high meta-cognition type showed a greater decline in scores than students of low meta-cognition type. Based on the results of this study, implications for research of online biology education and elementary science education are discussed.

The purpose of this study is to investigate college science students' and science teachers' understanding of chromosomal behavior in the context of cell division. The research problems were as follows: 1. What is the level of college science students' understandings of chromosomal behaviors? 2. What is the level of science teachers' understandings of chromosomal behaviors? 3. What is the level of understanding by grade and major area? The sample consisted of 28 sophomore, 17 junior and 23 senior biology students; and 23 middle school science teachers and 14 high school biology teachers. The instrument of the study was a short answer required paper and pencil test. The results of the study were as follows: 1) About 15 percent of the sample could not count the number of chromosome in a cell in appropriate. 2) Seventy percent of the students, and 80 percent of the teachers identified homologous chromosomes as ones with the similar shape and size, and 30 percent of the whole sample could not pair two homologous chromosomes. 3) About 70 percent of the students and 30 percent of the teachers could not mark corresponding allele on chromosome. 4) Biology major students showed higher understanding of overall chromosomal behaviors than non Biology students. Based upon the results, some implications were made. The major one was a development of a teaching model in which students can improve the ability to connect chromosome theory to mendelian genetics.

The main purpose of the study is to identify the key aspects of the use of innovative distance learning technologies in the training of biology students. Currently, there is a modernization, the evolution of the education system from a classical university to a virtual one, from lecture material teaching to computer educational programs, from a book library to a computer one, from multi-volume paper encyclopedias to modern search databases. During studies in higher education, distance learning ensures the delivery of information in an interactive mode through the use of information and communication technologies. The main disadvantage of distance learning is the emotional interaction of the teacher with students. It is necessary to increase the level of methodological developments for independent studies of students. The methodology includes a number of theoretical methods. Based on the results of the study, the main elements of the use of innovative distance learning technologies in the training of biology students were identified.

This paper describes the types of models that biology majors use and how they go about making their models in learning key concepts in biology such as the cell membrane, cytoskeleton and cell structure. Initially, a total of 44 biology students from all year levels enrolled in the second semester of calendar year 2008-2009 were asked to make their respective models of the cell membrane, cytoskeleton and cell structure. They were also asked to answer an open-ended questionnaire. Of the 44, only 20 (five from each year level) were randomly selected for a one-on-one interview. Results showed that the student-generated models from all year levels were mostly analogies, some textbook definitions and occasional drawings. In making their model, students first read the text; second, outline similarities in structure and function or both; and third, make the model. Data suggest that models are good diagnostic tools for identifying critical thinking skills of students. In this case, students mostly demonstrate the ability to recognize similarities in structure and function between the concept and their model. Some senior students demonstrated integration and reflective thinking in making their models. Thus, more opportunities for student-generated models must be available if students were to develop integration and reflective thinking in their models.

본 연구는 고등학생들의 생물 학습 상황의 소집단 활동에서 나타나는 상호작용 유형을 분석하고자 하였다. 상호작용의 유형 분석은 소집단 활동을 위해 교사가 피드백을 제공하고자 하는 면담 과정을 통해 이루어졌다. 상호작용의 유형은 학생과 학생, 학생과 교사간 상호작용 수준에 따라 4가지로 분류되었는데 이는 소집단 내에서 교사와 소집단의 대표 학생 사이에서만 상호작용이 이루어지는 유형(LR, Leader Representation), 일부 학생과 교사의 상호작용이 이루어지고 있는 유형(PSI, Partial Students Interaction), 학생과 학생 사이에 상호작용이 활발히 일어나나 교사와는 대표 학생과 상호작용이 이루어지는 유형(SAI, Students Active Interaction), 구성원 모두가 활발히 상호작용을 하고 모든 학생들이 교사와도 상호작용을 하는 유형(TSAI, Teacher-students Active Interaction) 등이다. 고등학생들은 면담 과정이 거듭될수록 학생과 학생 사이에 상호작용이 활발하게 일어났으며, 학습에 대한 개념 이해가 부족한 초기 단계에서는 학생들 간에 복잡한 상호작용 양상이 나타나지만 개념의 이해가 완성되어 갈수록 점차 상호작용 유형이 간결하게 변화되어가는 특성을 보였다. 이로부터 생물 학습을 위한 소집단에서의 상호작용은 개념 이해가 부족한 학습자에게는 개념을 확인하고 이해할 수 있는 기회를 제공하며, 학습 개념을 상호 형성할 수 있는 긍정적 영향을 미칠 수 있을 것이다.

This study was focused on analyzing students' informal reasoning patterns and their considerations in decision-making on socioscientific issues. This study involved 20 undergraduate students (10 biology majors and 10 non-biology majors) and showed how the two groups responded on socioscientific issues. Semi-structured interviews were conducted twice respectively based on six scenarios of gene therapy and human cloning. The result showed 93% of the total number of participants' decisions were made by rationalistic reasoning, whereas emotional reasoning was 49%, and intuitive reasoning was 27%. Students usually used two or three informal reasoning patterns together. Most of the students took more consideration on social factors. Some perceived ethical and moral implications of the issues, but they did not consider them seriously. They made their decisions depending on their own values, etc. 65% of the participants got their information on socioscientific issues from the mass media. Biology majors hardly used intuitive reasoning compared to non-biology majors. The Biology major group took into deep considerations on socioscientific issues while the non-biology major group seemed to interpret the given scenarios simply. This implied that the content knowledge was a significant factor of their decision-making. Therefore, it is necessary to develop proper science courses for non-major students to improve their decision-making on socioscientific issues. So, when we develop educational materials or programs, we should consider students' reasoning patterns, their considerations in decision-making, and their content knowledge. And because the mass media has the potential to play a key role for an effective education, we need to make a plan to make a practical application.
