Slovakian Students’ Knowledge of and Attitudes toward Biotechnology

This study examined university students’ knowledge of and attitudes (n = 378) toward biotechnology in Slovakia, a conservative country where the distribution of genetically engineered products are banned by law. We found a significant positive correlation between attitudes and the level of knowledge; however, although students enrolled in biology courses have better knowledge of biotechnology, their attitudes toward genetic engineering were similar than those of students who do not study biology. Females showed poorer knowledge and lower acceptance of genetically engineered products than did males. Overall, Slovakian students have poor knowledge and numerous misunderstandings about what genetic engineering means, which suggests that science curriculum with respect to this topic should be greatly re‐evaluated and teaching strategies should be improved accordingly.     

Investigating Urban Eighth-Grade Students’ Knowledge of Energy Resources

This study investigated urban eighth-grade students’ knowledge of energy resources and associated issues including energy acquisition, energy generation, storage and transport, and energy consumption and conservation. A 39 multiple-choice-item energy resources knowledge assessment was completed by 1043 eighth-grade students in urban schools in two cities in Pennsylvania, USA. Mean scores for the entire assessment measure indicated low conceptual energy knowledge of the eighth-grade students. Subscale means revealed that student understandings of energy resource acquisition, energy generation, storage and transport, and energy consumption and conservation are not satisfactory. Distractor analysis identified many misunderstandings that eighth-grade students hold with regard to energy resources. Findings revealed that students did not have a sound knowledge and understanding of basic scientific energy resources facts, issues related to energy sources and resources, general trends in the US energy resource supply and use, and the impact energy resource development and use can have on society and the environment. Implications for teacher enactment of energy resources curriculum activities are discussed.     

A Look into Students’ Retention of Acquired Nature of Science Understandings

Having the learning and retention of science content and skills as a goal of scientific literacy, it is significant to study the issue of retention as it relates to teaching and learning about nature of science (NOS). Then, the purpose of this study was to investigate the development of NOS understandings of students, and the retention of these understandings four months after being acquired through explicit reflective instruction in relation to two contexts. Participants were 24 tenth-grade students at a private high school in a city in the Middle East. Explicit NOS instruction was addressed within a six-week unit about genetic engineering. Three NOS aspects were integrated and dispersed across the unit. A questionnaire, together with semi-structured interviews, was administered as pre-, post-, and delayed post-test to assess the retention of participants’ NOS understandings. The questionnaire had two open-ended scenarios addressing controversial socioscientific issues about genetically modified food and water fluoridation. Results showed that most students improved their naïve understandings of NOS in relation to the two contexts following the six-week unit with the explicit NOS instruction. However, these newly acquired NOS understandings were not retained by all students four months after instruction. Many of the students reverted back to their earlier naïve understandings. Conclusions about the factors facilitating the process of retention as the orientation to meaningful learning and the prolonged exposure to the domain were discussed in relation to practical implications in the classroom.     

Students’ Perceptions of Their Science Teachers’ Pedagogical Content Knowledge

Pedagogical content knowledge (PCK) is a type of teacher knowledge to be developed by a teacher. PCK is said to contribute to effective teaching. Most studies investigated the development of PCK and its influence on students’ learning from the teachers’ perspectives. Only a limited number of studies have investigated the components of science teachers’ PCK that helped students’ learning from the perspective of students. Thus, it is the aim of this study to investigate the level of science teachers’ PCK from students’ perspective, in particular whether or not students of different achieving ability had different views of teachers’ PCK in assisting their learning and understanding. Based on the PCK research literature, six components of PCK have been identified, which were as follows: (1) subject matter knowledge, (2) knowledge of teaching strategies, (3) knowledge of concept representation, (4) knowledge of teaching context, (5) knowledge of students, and (6) knowledge of assessment in learning science. A questionnaire consisting of 56 items on a five-point Likert-type scale were used for data collection from 316 Form Four students (16 years old). One-way analysis of variance revealed that the differences in science teachers’ PCK identified by students of different achieving abilities were statistically significant. Overall, students of various academic achieving abilities considered all the components of PCK as important. The low-achieving students viewed all the components of PCK as being less important compared to the high and moderate achievers. In particular, low-achieving students do not view ‘knowledge of concept representation’ as important for effective teaching. They valued the fact that teachers should be alert to their needs, such as being sensitive to students’ reactions and preparing additional learning materials. This study has revealed that PCK of science teachers should be different for high and low-achieving students and knowledge of students’ understanding plays a critical role in shaping teachers PCK.     

Geoethics: Master’s Students Knowledge and Perception of Its Importance

In the 1990s, the field of geoethics started its development, associated with a set of ethical principles that regulate the profession of geologists in their relationship with society and with nature. Given the importance of this field, but also its youth, 36 higher education students attending a Master’s of Geology course were surveyed (20 were from an educational branch and 16 were from a scientific branch). The questionnaire applied to them aimed to achieve the following goals: (a) to identify the knowledge of the respondents about this new field and to verify their position about the inclusion of geoethics in the curriculum, (b) to understand how they consider the importance of geological knowledge in political decisions and (c) to investigate possible differences in the thinking of the respondents, given the specificities of their educational branches. The study concluded that the field of geoethics is unknown to the majority of the respondents. However, the recognition of its importance was also verified, after getting familiar with the definition of the concept, as well as the need for its inclusion in formal education. The respondents also considered relevant the creation of a deontological code that could provide geologists with ethical guidance. They also considered that geology should influence political decisions, but they did not consistently recognise the limits of its influence, which seems to reveal the need of a deeper understanding of the specific nature of geological knowledge when compared with other sciences. Almost all the results were similar in both groups, but the students from the educational branch offered more elaborate answers about the issues present in the questionnaire.     

The Effects of Motion Math: Bounce on Students’ Fraction Knowledge

National assessments suggest that many students do not display proficiency with fractions. Considering that time and materials are precious resources, many educators are looking to use technology to provide supplemental instruction with low demand on the instructor. The current study utilized a multiple-baseline design to examine the effects of the Motion Math: Bounce application on the fraction quantity comparison and number line placement skills of three fifth-grade students. Results indicate that Motion Math: Bounce improved the quantity comparison skills of all three participants and the number line skills of one participant. Additionally, all three participants made improvements from pre- to posttest on a measure of general fraction knowledge. Implications for future research and intervention implementation are discussed.     

Nursing Students’ Perceptions of a Silent Mentor Program in an Anatomy Course

Anatomy is a core course in undergraduate nursing curriculum. In today’s nursing profession, the integration of biosciences and humanities is increasingly emphasized. Anatomy is considered one of the most essential bioscience subjects for nursing practice. Thus, integrating a silent mentor program into the anatomy course can enrich the knowledge of undergraduate nursing students regarding biosciences and humanities and enhance their future patient-centered care competencies. This article aimed to understand the students’ perceptions of integrating a silent mentor program into the anatomy course. Qualitative approach included four focus group interviews. Themes were developed using the analytic induction technique. Twenty-five second-year undergraduate nursing students from a university were recruited. Semi-structured interviews were used to guide four focus group interviews. Focus group interviews were digitally recorded, transcribed, and analyzed. According to the preliminary findings, nursing students regarded silent mentors not only as teaching tools but also as tools to learn more than anatomy. Students greatly respected the silent mentors and were highly engaged in the anatomy course. They expected to become better students or future nurses. Four themes were identified from the interviews: emotional transformation, caring spirit, course engagement, and self-expectation. The findings suggest that the silent mentor program offered students a beneficial learning experience and stimulated their developing competency in nursing humanities. How the silent mentor program can help students achieve optimum academic performance and how their positive experience of the program and humanistic spirit translates into clinical practice in future should be studied further.

Impact of Secondary Students’ Content Knowledge on Their Communication Skills in Science

The expert blind spot (EBS) hypothesis implies that even some experts with a high content knowledge might have problems in science communication because they are using the structure of the content rather than their addressee’s prerequisites as an orientation. But is that also true for students? Explaining science to peers is a crucial part of cooperative learning methods such as the “jigsaw method”. Our study examined the relationship between science communication competence (SCC) and content knowledge (CK) of 10th-grade students (N = 213). Using latent class analysis, we identified two types of students with a different relationship between CK and SCC. Using path analysis, we found that the first type of 109 students primarily used their science CK as the “resource” for addressee-oriented science communication and both their SCC and their CK were correlated with each other. For the second type of 104 students (who used other resources), their CK even had a small negative effect on their SCC. Using t tests, we found that those students primarily using their CK as the resource for communication performed significantly worse in the communication test than did those students who used other resources. Using the EBS hypothesis, we suggest that students’ CK might have ambiguous effects in communication if the content structure—rather than their addressee’s prior knowledge—is used as the primary orientation for communication. We suggest that an effective use of cooperative learning techniques in classroom requires a special prior training for their science communication skills.     

The Effects of Prior Knowledge and Audience on High School Students’ Writing

Abstract

To investigate the likelihood that explicit instruction in text summarization is being provided in classrooms, an "ideal lesson" method was used. Twelve experienced K-12 teachers were asked to devise summarization lessons appropriate to their learners and course content, to deliver the lessons, and to audiotape them. Lessons were transcribed, and instances of mentioning of summarization rules were coded. Only two teachers in the sample group discussed more than one of the five summarization rules assessed. The other teachers provided instruction that emphasized words and facts, despite their having been prompted to "assist students in improving text summaries." Staff development possibilities are discussed.     

Elementary and Middle School Students’ Conceptions of Knowledge,Information, and Truth

Although the study of epistemic beliefs has received growing interest in the past decades, this research tends to focus on high school and undergraduate students, and does not address beliefs about information and truth, concepts that have been regarded as critical for learners in 21st-century educational contexts. In this study, the authors examined 87 elementary and middle school students’ beliefs about the definitions of and relations among knowledge, information, and truth through the use of a graphical and justification task, and addressed the consistency of beliefs across contexts and domains. Results indicated that students tended to regard knowledge, information, and truth as interrelated, and the majority of students described their beliefs as consistent across contexts and domains.     

Appraising the Qualities of Social Work Students’ Theoretical Knowledge: A Qualitative Exploration

Higher professional education aims to prepare students for entering practice with an adequate theoretical body of knowledge. In constructivist programmes, authentic learning contexts and self-directed learning are assumed to support knowledge learning and the transition from education to practice. Through an in-depth exploration, this case study aimed at defining and assessing the qualities of social work students?? theoretical knowledge at initial qualification. Participants were final-year bachelor??s students (n?=?18) in a constructivist professional programme of social work. Students?? knowledge concerning a real-life practical case was elicited through an interview and a form of concept mapping. A six-step procedure was used for a qualitative appraisal of students?? knowledge with the assistance of seven expert teachers. During this procedure an instrument for analysing knowledge qualities was developed, comprising 13 aspects representing four features of expert knowledge: extent, depth, structure, and critical control. Results showed that 13 students received high appraisals for their knowledge extent and depth. Only 4 students received high appraisals for knowledge structure and critical control. 5 Students who received overall lower appraisals seemed inhibited to show their knowledge qualities by preoccupations with self-concerns about their own professional role. Conclusion is that the majority of students needs more learning support for knowledge structure and critical control than offered by their constructivist programme. Further research is needed into the personal factors that influence students?? theoretical knowledge learning and which knowledge qualities can be reached by young adults in a 4?year educational programme.

Students’ conceptions of biology

The argument in this paper has two parallel strands. One describes students’ conceptions of biology; the other uses Habermas’ epistemological framework as a way of suggesting alternative curricular questions. The two strands are brought together, since the research methodology is the situational‐interpretive curriculum orientation, and the findings are considered from this orientation. Thus, the data from the first strand is examined from the second strand, and consequently, new questions arise.

With traditional knowing, science education researchers “know” how students conceive of the science they are learning by having students react to statements of the researcher's conception of science. This way of knowing has been criticized because it depends upon the researcher's set of ways of looking at students’ conceptions. As such, it does not treat students’ knowledge as a first‐order phenomena; knowing is, rather, a second‐order phenomena since it is filtered through another person's conceptions. In this study the Habermasian framework is used as an alternative perspective of knowledge which allows students’ conceptions to be examined at the level at which the conceptions were constructed.

The study suggests that students conceptualize biology from three distinct philosophical positions; but when these positions are considered from the Habermasian framework, they all are examples of the empirical‐analytic tradition. As such, the students’ conceptions have not gone beyond explanatory knowledge, and this raises questions about the curriculum.     

Students’ images of mathematics

Students’ judgments about “what counts” as mathematics in and out of school have important consequences for problem solving and transfer, yet our understanding of the source and nature of these judgments remains incomplete. Thirty-five sixth grade students participated in a study focused on what activities students judge as mathematical, and how they make their judgments. Students completed a photo sorting activity; took, viewed, and captioned their own photos of mathematics; viewed and commented on classmates’ photos; and participated in a small group discussion. Across multiple sources of data, findings showed that students attended to two major features of photos and activities when making judgments: surface cues present in the photos, such as numbers and money, and the possibility for mathematical action. Some students looked for the possibility of mathematics, while others asked if mathematics was necessary. Students also gave higher ratings to activities with which they had personal experience. The article concludes with possible implications for practice.     

A Study of General Education Astronomy Students’ Understandings of Cosmology. Part V. The Effects of a New Suite of Cosmology Lecture-Tutorials on Students’ Conceptual Knowledge

This is the final paper in a five-paper series describing our national study of the teaching and learning of cosmology in general education astronomy college-level courses. A significant portion of this work was dedicated to the development of five new Lecture-Tutorials that focus on addressing the conceptual and reasoning difficulties that our research shows students have with frequently taught cosmology topics, such as the expansion of the universe, the Big Bang, and dark matter. We conducted a systematic investigation of the implementation of these new Lecture-Tutorials and resulting learning gains in order to test the efficacy of these new Lecture-Tutorials. Our investigation included classroom observations, results from pre–post testing using four conceptual cosmology surveys, and comparisons between classes in terms of the class time spent on cosmology topics and other instructional strategies used to teach cosmology. We used this combination of qualitative and quantitative research results to evaluate the conceptual understandings of students who used the new cosmology Lecture-Tutorials compared to those students who did not. The analysis of our data shows that, in many cases, classrooms that used the cosmology Lecture-Tutorials saw a greater increase in their students’ conceptual cosmology knowledge compared to classrooms that did not use the cosmology Lecture-Tutorials. However, our results also indicate how instructors implement the Lecture-Tutorials into their classrooms strongly influences their students’ learning gains.     

Students as Consumers of Knowledge: Are They Buying What We’re Selling?

Academic entitlement, an attitude marked by students’ beliefs that they are owed something in the educational experience apart from what they might earn from their effort, has received attention recently in the literature. In previous work, academic entitlement has been shown to be related to parenting styles and personality constructs. The current study departs from previous research by taking a phenomenological approach to understanding academic entitlement. Focus groups were conducted with a total of 52 first-year students. Responses were coded into six facets of academic entitlement: product value of education, social promotion, role of professors, teaching assistants, administrators, and shoppers or scholars.
