The purpose of this study was to survey junior high school teachers' and students' perceptions on the science textbooks. Subjects of this study were 113 science teachers and 715 students from junior high schools in Daegu and Kyungpook area. As statistical method, one-way ANOVA and t-test were used to check differences of the perceptions between teachers and students. Teachers had different perceptions by school location and class size, while students had different perceptions by school location, co-ed, class size, and grade level. Both teachers and students having the relativistic viewpoint on textbook knowledge regarded the knowledge as relativistic one, and preferred the student-centered textbooks. Teachers liked textbooks written by the student-centered view more than students did. Teachers had the more absolutistic viewpoint on textbook knowledge and on teaching, while students liked the electronic textbooks more than teachers did.

Although cooperative learning strategies in many subject areas have been found to be effective, the effect of cooperative learning on academic achievement in science laboratory setting is not clear. Reported results on the effects of the strategies for higher achieving students are not also consistent. In this study, the cooperative learning strategies emphasizing student-centered learning which included higher order thinking activities were used in a elementary school science course. The cooperative and traditional learning groups were selected from fifth-grade classes, and taught about dissolution and solution for 16 class periods. The effects of the cooperative learning strategies upon students' academic achievement, science process skill, the attitude toward science instruction, and the perceptions of classroom environment were investigated. Two-way ANCOVA results revealed that the test scores of academic achievement and science process skill for the cooperative learning group were significantly higher than those of the traditional learning group. No interaction between the instruction and the level of previous achievement was found. The perceptions of confliction were higher in cooperative learning group. In the attitude toward science instruction and the perceptions of participation, however, no significant difference between the two groups was found. Educational implications are discussed.

Based on the importance of visual representation for scientific understanding, this study applied visual thinking in elementary science classes. This study analyzed elementary students' visual thinking and investigated the instructional influences. Students' perceptions on the class applying visual thinking were also investigated. The subject were 38 fourth grade students, 18 in experimental group and 20 in control group. For the unit of 'Shadow and mirror', on-line and off-line blended classes were applied in both group because of COVID-19. The experimental group student were asked to construct their own visual thinking, while the control group students used traditional workbook. The results were as follows. First, students' visual thinking can be classified into three different types, which are 'activity recall type', 'result summary type', and 'core concept representation type' based on what they represent rather than how they represent. Second, applying visual thinking in science class showed significant effects on science academic achievement, science related attitude, and creative academic efficacy. Third, students' perceptions on applying visual thinking in science classes were very positive. Students perceived visual thinking activities were interesting and helpful for understanding science. Educational implications of applying visual thinking in elementary science classes were discussed.

This study investigated high school student and chemistry teacher perceptions on the effect of water vapor in the air on evaporation and boiling of water by a questionnaire. In science textbooks evaporation and the boiling of water are related to the vaporization concept, boiling is related to vapor pressure and air pressure, and vapor pressure is related to the vapor concept in the air. High school student and chemistry teacher perceptions on these linkages were compared. Science textbooks were also analyzed for reasons behind these diverse perceptions. Results revealed that a majority of students conceptualized that vapor in the air was related to evaporation and boiling, but were unable to distinguish the evaporation phenomena at the macroscopic level and the evaporation of water molecules at the microscopic level. They also thought that vapor in the air affected vapor pressure and boiling. Although the percentage of teacher scientific conception was higher, a great number of teachers had diverse perceptions on evaporation and boiling just as students had. Common explanations of evaporation and boiling phenomena in science textbooks were at the macroscopic level. Moreover, there were few connections of concepts even if the explanations were at the microscopic level.

One of the impacts of Covid-19 on education systems has been the shift to online education. This shift has changed the way education is consumed and perceived by students. However, the exact nature of student perception about online education is not known. The aim of this study was to understand the perceptions of Saudi higher education students (e.g., post-school students) about online education during the Covid-19 pandemic. Various aspects of online education including benefits, features and cybersecurity were explored. The data collected were analysed using statistical techniques, especially artificial neural networks, to address the research aims. The key findings were that benefits of online education was perceived by students with positive experience or when ensured of safe use of online platforms without the fear cyber security breaches for which recruitment of a cyber security officer was an important predictor. The issue of whether perception of online education as a necessity only for Covid situation or a lasting option beyond the pandemic is a topic for future research.

Since 1998, an elementary teacher education institute in Korea has hosted the center for the gifted education. The institute hired undergraduate students to escort and liaison each class of the gifted student participants with assisting classroom activities. These liaison teachers observed the gifted classroom activities and evaluated them by using a given checklist and filling out pre-made evaluation forms. Currently this system is being transferred from part-time jobs for students to earn allowance into well organized pre-service teacher program focusing on the gifted education. In other words, the purpose of system is being shifted from how liaison teachers facilitate the gifted program to how the system helps the liaison teachers to be quality teachers for the gifted who can understand what the gifted are and how to facilitate them. Analyzed were the self reports of the liaison teachers regarding their perceptions and beliefs of the gifted and their education program. It was found participant liaison teachers purposed to have more live experiences with getting along with students as well. Liaison teachers’ perceptions on establishing a gifted teacher professional education sequence were reported in this study. The potential scaffolding of the pre-service teacher education program model of the gifted education was provided as a consequence of this study.

Students' engagement is very important for effect science learning. Multidimensional approaches on students' engagement defines engagement in three ways which includes cognitive, behavioral, and cognitive engagement. Based on the multidimensional approaches on students' engagement, this study identified latent groups of elementary students characterized by patterns of cognitive, behavioral, and emotional engagement in science classes. This study also compared students' perceptions of their engagement in general science classes and small-group activities by the latent groups. 377 elementary students were involved in this study. 5-scale Likert survey were used in order to investigate students' engagement in science classes. Latent class analysis using Mplus program identified 3 latent groups of students engagement in science classes: Highly engaged, moderately engaged, and minimally engaged in three ways of engagement. The mean scores of cognitive, behavioral, and emotional engagement were significantly different by three latent groups. In addition, there were significant difference in students perceptions on participating experiments activities and carefully listening of teacher among latent groups. However, there was no significant difference in students' perceptions on their actions during small-group activities. Educational implications were discussed.

The purposes of this study was to analyze qualitatively changes in students' experience and perceptions in relation to studying science using portfolios and any resultant effects on the portfolio itself. Five fourth-grade elementary students from one small city participated in this study. Data was collected through interviews as well as through student portfolios containing the science content matter of two units over two weeks. Observational diaries recorded by a teacher were also used to test the reliability of data collection. All interviews with students were transcribed to develop a suitable network to categorize students' responses. Students' portfolios were analyzed in order to reveal their essential characteristics in combination with their teacher's observational diaries. The results were as follows. First, student perceptions of their portfolios were categorized into three different levels; superficial, extended, and moderate perceptions. The changes in perception could also be divided into three levels; consistent-superficial, unstable, and a progressive-extended pattern. Second, the experience of students with their portfolio were investigated in terms of the following; successfully completing the elements of the portfolio, development of evidence, interaction with peers, teachers, and parents, and the standards of evaluation used for the portfolios. Third, the perceptions and experience of working on the portfolio by students had a number of direct effects on the way in which students actually created and developed their portfolios. Finally, students with positive attitudes towards their portfolios actively participated in the portfolio experience and finally understood what it meant completely. However, students with negative attitudes regarding portfolio based work, did not leave the experience with any heightened awareness of the utility or indeed, purpose of portfolio based work.

The purpose of this study was to investigate teachers' perceptions of gender differences in students' mathematics and science learning ability. The sample included 289 elementary and secondary school gifted teachers. The teachers filled out the survey, asking their perceptions of gender differences in mathematics and science learning ability, as well as of the reasons of the differences. The results were as follows: 1) 65% of the teachers responded that gender differences existed in students' mathematics and science learning ability, 2) 63% of the teachers perceived that the differences began around higher elementary or middle school ages, 3) 57% of the teachers thought that gender differences existed in the high-achieving student group. Teachers perceived the reasons of differences were 1) differences in inborn ability, 2) the different expectation, and 3) the different ways of parental cares. Since teachers' perceptions of students' ability would impact teachers' attitudes on students, implications and suggestions were included in this article to provide teachers insights that promote students' better learning.

For this study we conducted a survey far elementary students from 3rd to 6th grade. We performed a frequence test using statistic program and the cross-tabs between gender and grade. We then conducted a thorough interview with the students, after constructing several meaningful questions reflecting the results of survey. As a result of this study, it was critical to arrange interesting inquiry activities in order to foster student's preference for science and attract them to get involved in the science class. We found that teachers were needed to be more flexible to make a group during the classes and teachers would succeed to reflect student's characteristics. In addition, it is necessary for the teachers to refrain from excessive advising or immoderate interrupting student's experiment activity. We conclude that only when the improvements in the curriculum for science education should be made, teachers would allow students to recognize its significances by themselves, and let them follow the inquiring process during the laboratory class for themselves.
