A Conceptual Characterization of Online Videos Explaining Natural Selection

Educational videos on the Internet comprise a vast and highly diverse source of information. Online search engines facilitate access to numerous videos claiming to explain natural selection, but little is known about the degree to which the video content match key evolutionary content identified as important in evolution education research. In this study, we therefore analyzed the content of 60 videos accessed through the Internet, using a criteria catalog with 38 operationalized variables derived from research literature. The variables were sorted into four categories: (a) key concepts (e.g. limited resources and inherited variation), (b) threshold concepts (abstract concepts with a transforming and integrative function), (c) misconceptions (e.g. that evolution is driven by need), and (d) organismal context (e.g. animal or plant). The results indicate that some concepts are frequently communicated, and certain taxa are commonly used to illustrate concepts, while others are seldom included. In addition, evolutionary phenomena at small temporal and spatial scales, such as subcellular processes, are rarely covered. Rather, the focus is on population-level events over time scales spanning years or longer. This is consistent with an observed lack of explanations regarding how randomly occurring mutations provide the basis for variation (and thus natural selection). The findings imply, among other things, that some components of natural selection warrant far more attention in biology teaching and science education research.     

The Role of Family Characteristics for Students’ Academic Outcomes: A Person‐Centered Approach

Using data from 1,571 ninth‐grade students (M_age = 14.62) from 82 academic track schools in Germany and their predominantly Caucasian middle‐class parents, configurations of different family characteristics reported by parents were investigated. Latent profile analyses considering academic involvement, family interest, parents’ self‐concept, child's need for support, and parents’ time and energy identified average, indifferent, motivated and engaged, motivated and disengaged, and involved families. Cross‐sectional and longitudinal associations with students’ motivational (self‐concept, effort, and interest) and achievement outcomes (achievement test and grades) in math were analyzed. Students from families classified as motivated and disengaged showed higher initial levels motivation and achievement. Over 5 months, these students also showed an increase in self‐concept and higher achievement than students from other family types.     

Influences of family based prerequisites,reading attitude,and self-regulation on reading ability

This study investigated the effect of self-regulated learning, as indicated by academic self-concept, motivation and learning strategies, reading attitude and family based prerequisites on reading ability. Students (n = 4018) in the eighth grade answered the IEA reading literacy test, the self-regulated learning questionnaire and a student questionnaire about their background. The exploratory factor analysis (EFA) revealed that the self-regulated learning questionnaire did not measure the intended three dimensions, but only two: Verbal/General academic self-concept and a new dimension called Goal oriented strategies. Structural Equation Modelling (SEM) with a cross-validation sample was conducted to determine the effects in the final model. The strongest effect on reading ability was from Verbal/General academic self-concept (β = .43 for final and β = .56 for cross-validation model). Gender differences revealed that girls read better on narrative and expository texts, had a more positive reading attitude, and more positive verbal self-concept, whereas boys had a higher academic self-concept (not domain-specific), self-efficacy, control expectation, reported more memorising, elaboration, and instrumental motivation (all differences p < .001).     

The reasons students choose teaching professions

The purpose of the paper is to present the reasons students at the Faculty of Education in Maribor, Slovenija, chose pedagogy for their study direction, and therefore becoming a teacher. A total 237 second‐year students of the academic year 2003/04 were included in the research. Of the five groups of reasons for choosing this program (altruistic, material, self‐realization and alternative, and reasons arising from aspiration stereotype), students most often asserted self‐realization, including: teaching provides a useful public function for the whole society; as a teacher, I can be an example to children and young people; this profession will give me a chance for professional development during my whole career; and teaching will enable me to use all my abilities (and talents—for example, music, verbal, dancing, etc.) Important differences were found to exist between students of different disciplines.     

Data-driven assessment of teacher candidates during their internships in deaf education

Deaf education teacher training programs have received criticism for graduating students with gaps in knowledge and skills required for specific placements. The National Council for Accreditation of Teacher Education (NCATE) requires that accredited programs engage in self-study, and NCATE guidelines require programs to collect valid, reliable evidence of teacher candidate performance and candidates' effect on student learning. In the present study, an ecobehavioral assessment computer program, MS-CISSAR (Mainstream Code for Instructional Structure and Student Academic Response), was used in evaluations of 8 teacher candidates during internship experiences. Results were mixed. Some of the instructional arrangements, teaching behaviors, and student responses resembled those found in studies using in-service teachers as subjects; however, some data revealed a need for changes in instruction. Data gathered with MS-CISSAR could be added to evaluations to help training programs meet NCATE requirements for evidence on teacher candidate performance and candidates' effect on student learning.     

The Use of Online Modules and the Effect on Student Outcomes in a High School Chemistry Class

The purpose of the study was to review the efficacy of online chemistry simulations in a high school chemistry class and provide discussion of the factors that may affect student learning. The sample consisted of 351 high school students exposed to online simulations. Researchers administered a pretest, intermediate test and posttest to measure chemistry content knowledge acquired during the use of online chemistry laboratory simulations. The authors also analyzed student journal entries as an attitudinal measure of chemistry during the simulation experience. The four analyses conducted were Repeated Time Measures Analysis of Variance, a three-way Analysis of Variance, Logistic Regression and Multiple Analysis of Variance. Each of these analyses provides for a slightly different aspect of factors regarding student attitudes and outcomes. Results indicate that there is a statistically significant main effect across grouping type (experimental versus control, p = 0.042, α = 0.05). Analysis of student journal entries suggests that attitudinal factors may affect student outcomes concerning the use of online supplemental instruction. Implications for this study show that the use of online simulations promotes increased understanding of chemistry content through open-ended and interactive questioning.     

Developing narratives as a pedagogical approach to fostering professional interpersonal competences

The study examined a project aimed at helping students develop professional interpersonal skills. Groups of university students in social work, teacher training, and a student mentoring program for children at-risk participated in seminars where they developed narratives derived from personal experience in interaction with others. The theoretical framework for the project was inspired by the idea of “stories to live by” developed by Clandinin and Connelly. Data for the study were collected from questionnaires, interviews, and focus groups. Results indicated that narrative-building activities, when implemented in a structured and consistent manner, can contribute to improving empathy and perspective-taking abilities, developing self-knowledge, and enhancing communication skills.
