Prediction/discussion-based learning cycle versus conceptual change text: comparative effects on students’ understanding of genetics

Background and purpose:

The purpose of this study was to investigate the comparative effects of a prediction/discussion-based learning cycle (HPD-LC), conceptual change text (CCT) and traditional instruction on 10th grade students’ understanding of genetics concepts.

Sample:

Participants were 112 10th basic grade male students in three classes of the same school located in an urban area. The three classes taught by the same biology teacher were randomly assigned as a prediction/discussion-based learning cycle class (n?=?39), conceptual change text class (n?=?37) and traditional class (n?=?36).

Design and method:

A quasi-experimental research design of pre-test–post-test non-equivalent control group was adopted. Participants completed the Genetics Concept Test as pre-test–post-test, to examine the effects of instructional strategies on their genetics understanding. Pre-test scores and Test of Logical Thinking scores were used as covariates.

Results:

The analysis of covariance showed a statistically significant difference between the experimental and control groups in the favor of experimental groups after treatment. However, no statistically significant difference between the experimental groups (HPD-LC versus CCT instruction) was found.

Conclusions:

Overall, the findings of this study support the use of the prediction/discussion-based learning cycle and conceptual change text in both research and teaching. The findings may be useful for improving classroom practices in teaching science concepts and for the development of suitable materials promoting students’ understanding of science.     

Activating Students’ Argumentative Resources on Socioscientific Issues by Indirectly Instructed Reasoning and Negotiation Processes

The present study analyses the impact of negotiation processes on activating argumentative resources for decision-making in a socioscientific issue (SSI) in biology classes. The research focuses on the potential of group-based negotiation processes to activate the use of relevant argumentative resources without any prescribed or explicit instructions on these resources and arguments. In the corresponding intervention with a pre-post-design, students are encouraged to reason and weight their own arguments, which are based on protecting local biodiversity. The students have to reason and weight individually (pre-phase) immediately before they discuss their own reasoning and weighting with others in groups (treatment). The students have to then, once again, reason and weight their arguments individually (post-phase). The students are instructed, during these three steps (pre-phase, treatment, post-phase), using an educational tool, target-mat, which structures the reasoning and weighting visually, but does not prescribe the way of argumentation. By analysing the students’ argumentative resources, normative and fact-based elements can be measured immediately before and after the negotiation process. In terms of the pre-phase, the use of differing and appropriate argumentative resources can be analysed in relation to different arguments. The pre- and post-comparison reveals relevant changes leading to a substantial increase of the quality of reasoning. Therefore, in a student-centred decision-making process with minimal guidance, students are encouraged to become aware of the appropriateness of different argumentative resources.

     

A Pilot Study Examining Religious Organization Affiliation,Sexual Health Information Sources,and Sexual Behaviors Among College Students

We conducted an online survey to examine religiosity, sexual health knowledge, and behavior and sexual health information sources among undergraduate students affiliated with student religious organizations (n?=?45) and unaffiliated students (n?=?82). Analyses included Fisher’s exact tests, t-tests, and exact regression models. Students reporting religious affiliation considered religious sources to be believable (p?=?.004 for sexual health; p?p?=?.0042). Although religiously affiliated students reported fewer sexual partners in the past year (p?=?.020), their reported condom use was not significantly different from that of unaffiliated students. Future research should explore the focus and content of romantic relationship information provided by student religious organizations. Health practitioners and educators should consider strategies for collaborating with religious organizations to meet the information needs of these students.     

The Effect of Animated Node-Link Displays on Information Recall

The attentional effects of animation on the processing of information from node-link maps and text were explored. The authors randomly assigned college students to receive a static node-link map presentation (n =40), an animated node-link map presentation (n =37), a static text presentation (n =29), or an animated text presentation (n =27). The participants were asked to recall the information 48 hr later. The participants recalled more main-idea information from animated node-link maps than from static maps or animated text. There were no differences with regard to presentation or display format on the recall of microstructural information.     

An analysis of the different patterns of 1:1 interactions between educational professionals and their students with varying abilities in inclusive classrooms

The purpose of this study was to examine the different types and patterns of 1:1 interactions provided by general educators, special educators and paraprofessionals to children with mild disabilities (n?=?13), severe disabilities (n?=?13), and children without disabilities (n?=?13) in inclusive classrooms. General educators, special educators, and paraprofessionals' 1:1 interactions with students in three comparison groups were recorded in 17 elementary and middle school classrooms using a partial interval observation system. We found significant differences with respect to interaction frequency and content. Teachers and paraprofessionals had consistently more 1:1 interactions with students with severe disabilities, followed by children with mild disabilities, and then students without disabilities. In comparison to special education teachers and paraprofessionals, general educators interacted significantly more frequently with children without disabilities and children with mild disabilities. In contrast, paraprofessionals interacted significantly more often with students with severe disabilities and less frequently with children with mild disabilities and students without disabilities. Instructional interactions in social, behavioural, and functional domains were infrequent in these classrooms. We conclude with a brief discussion of the implications of these findings for future research and practice.     

Environmental attitudes of young people in Turkey: effects of school type and gender

The purpose of this study is to investigate the effect of school type (private and public) and gender on sixth, seventh, eighth and tenth grade students’ attitudes toward the environment. A total of 1497 students (n?=?765 girls; n?=?715 boys; and n?=?17 gender not provided) attending public (n?=?603) and private schools (n?=?892) located in Ankara participated in the study. A 45‐item Likert‐type questionnaire consisting of four dimensions, namely, awareness of environmental problems, national environmental problems, solutions to the problems and awareness of individual responsibility, was used to measure students’ environmental attitudes. A two‐way multivariate analysis of variance (MANOVA) was conducted to determine the effect of school type and gender on four dimensions of the environmental attitude questionnaire. Results showed that school type and gender had a significant effect on the collective dependent variables. Univariate ANOVAs indicated that mean scores on each dimension of the questionnaire were significantly different for students in public and private schools. Moreover, there was statistically significant mean difference between boys and girls with respect to scores on each dimension of the questionnaire. It is concluded as a result of the study that, although there are differences between categories of individuals, there is a widespread support for conservation of the environment among young people living in Ankara/Turkey.     

Adolescents’ Social Networks: Exploring Different Patterns of Socio-Digital Participation

The purpose of the study was to assess adolescents’ participation in various socio-digital activities by using a self-report questionnaire, a social networking questionnaire, and interviews. The participants (n?=?253) were grade 6–9 students from a multicultural lower-secondary school in Finland. Three profiles of socio-digital participation were identified: friendship oriented basic participators (n?=?161), gaming-oriented participators (n?=?61), and creative participators (n?=?31) intensively engaged in diverse socio-digital practices. The analyses revealed systematic differences in social networking relations as a function of adolescents’ social-digital participation profile and gender. The reciprocal values in hanging out, liking, and media multiplexity were highest for creative participators, whereas gaming-oriented participators were less socially active than their peers. The socio-digital expertise of creative participators was socially recognized by a larger group of peers than that of the other groups. The study produces methodological tools suitable for collecting systematic longitudinal data of socio-digital practices of larger groups of adolescents in future.     

Predictors of psychological distress and well-being in a sample of Australian undergraduate students

Previous research has found university students report higher levels of psychological distress compared to the general population. Our aim was to investigate the degree to which personality and contextual factors predict psychological distress and well-being in students over the course of a semester. We also examined whether resilience-building skills, such as positive self-talk, mindfulness meditation and self-management, included in a first-year psychology subject, might reduce distress and improve well-being. Undergraduate first-year students (n?=?150) completed a battery of questionnaires in week three (Time 1; n?=?150) and week 10 (Time 2; n?=?53) of semester. At both times students reported high levels of psychological distress, as measured by the K10, the General Health Questionnaire and the Brief Symptom Inventory, and low levels of psychological well-being, as measured by the Warwick Edinburgh Mental Well-Being Scale. Students exposed to resilience-building skills embedded in a subject (n?=?24) were no less distressed at Time 2 than those not enrolled in that subject (n?=?29). The personality traits of emotional resilience (vs. reactivity) and bounce-back resilience measured at Time 1 were the only significant predictors of psychological distress and well-being measured at Time 2. Students with high emotional and bounce-back resilience had lower psychological distress and higher well-being scores. Future research could consider development and trial of a full semester university subject designed to improve students’ resilience knowledge and skills.     

Degrees of co-creation: an exploratory study of perceptions of international students’ role in community engagement experiences

Increased competition for the international student market has motivated universities to modernize their marketing strategies. Community engagement is an important component of students' international university experience and represents a potential point of competitive advantage. Developing marketing strategies around university–student–community engagement (U–S–CE) requires an understanding of the perspectives of international students, the university and the community. We anchored our study in value co-creation which is a principle of the service dominant logic framework found in the marketing literature. With limited research in the area, a qualitative approach was appropriate. Interviews were undertaken with key university members (n?=?4) and community members (n?=?5) concurrently with focus groups of international students (n?=?22) at a single university. Based on the degree of co-creation by international students in U–S–CE, three groups emerged: consumers, collaborators and co-designers. This study offers theoretical and practical insight, providing a platform for further research into U–S–CE.     

Development of software to support argumentative reading and writing by means of creating a graphic organizer from an electronic text

This paper describes the development of a software program that supports argumentative reading and writing, especially for novice students. The software helps readers create a graphic organizer from the text as a knowledge map while they are reading and use their prior knowledge to build their own opinion as new information while they think about writing their essays. Readers using this software can read a text, underline important words or sentences, pick up and dynamically cite the underlined portions of the text onto a knowledge map as quotation nodes, illustrate a knowledge map by linking the nodes, and later write their opinion as an essay while viewing the knowledge map; thus, the software bridges argumentative reading and writing. Sixty-three freshman and sophomore students with no prior argumentative reading and writing education participated in a design case study to evaluate the software in classrooms. Thirty-four students were assigned to a class in which each student developed a knowledge map after underlining and/or highlighting a text with the software, while twenty-nine students were assigned to a class in which they simply wrote their essays after underlining and/or highlighting the text without creating knowledge maps. After receiving an instruction regarding a simplified Toulmin’s model followed by instructions for the software usage in argumentative reading and writing along with reading one training text, the students read the target text and developed their essays. The results revealed that students who drew a knowledge map based on the underlining and/or highlighting of the target text developed more argumentative essays than those who did not draw maps. Further analyses revealed that developing knowledge maps fostered an ability to capture the target text’s argument, and linking students’ ideas to the text’s argument directly on the knowledge map helped students develop more constructive essays. Accordingly, we discussed additional necessary scaffolds, such as automatic argument detection and collaborative learning functions, for improving the students’ use of appropriate reading and writing strategies.

     

The Effect of Task Instructions on Students’ Use of Repetition in Argumentative Discourse

The reasoning belief of argumentum ad nauseam assumes that when someone repeats something often enough, he or she becomes more convincing. The present paper analyses the use of this strategy by seventh-grade students in an argumentation task. Sixty-five students (mean age: 12.2, SD?=?0.4) from a public school in a mid-sized urban environment took part in the study. The students were asked to either argue to convince an opposing partner or argue to reach consensus with an opposing partner on three dilemmas that dealt with energy sources. Data were gathered according to a between-groups design that included one independent variable (argumentative goal: to convince vs. to reach consensus) and one dependent variable (the degree of argumentative repetitions). We predicted that in the condition to convince their partner, the students would use the repetition strategy more often in their attempts to be persuasive. Our findings show that the mean number of argumentative repetitions was significantly higher for the persuasion group for both of the most frequent argumentative structures (claim and claim data). The mean percentage of repeated claims for the persuasion condition was 86.2 vs. 69.0 for the consensus condition. For the claim data, the mean percentage for the persuasion group was 35.2 vs. 24.3 for the consensus group. Also, students in the persuasion group tended to repeat one idea many times rather than repeating many ideas a few times within the same argumentative structure. The results of our study support the hypothesis that the goal of the argumentative task mediates argumentative discourse and, more concretely, the rate of repetitions and the conceptual diversity of the statements. These differences in rates of repetition and conceptual diversity are related to the amount of learning produced by the instructional goal. We apply Mercer's idea that not all classroom argumentation tasks promote learning equally.     

Development of argumentative discourse based on learning demand / Evolución del discurso argumentativo en función de la demanda de aprendizaje

Abstract

This study is part of a larger project focused on the development of argumentative competence and its effect on knowledge construction. It aims to analyse and compare the changes in the evolution of the claims and the quality of the written arguments used by university students in two learning scenarios: a first scenario where students participated in a debate with the aim of convincing; and a second scenario where the debate was aimed at achieving an agreement by consensus. The participants were 77 first-year university students in Education and Speech Therapy. A quasi-experimental design was adopted with repeated measures, in which students from the two groups wrote two argumentative texts (initial and final) for each type of debate. The results indicate that the initial claims evolved towards more moderate positions at the end of the process; and the quality of the arguments that students wrote in their texts varied significantly depending on the type of demand and the time of writing (initial or final).     

When academics integrate research skill development in the curriculum

This study considered outcomes when 27 academics explicitly developed and assessed student research skills in 28 regular (non-research methods) semester-length courses. These courses ranged from small (n?=?17) to medium-large (n = 222) and included those from first year to masters in business, engineering, health science, humanities and science, across five universities in three Australian cities. The two-year study used three data sets to determine the outcomes of development and assessment initiatives: student pre- (n?=?779) and post-questionnaires (n?=?601), interviews with students (n?=?46) one year after completing a course that developed research skills and interviews with academics (n?=?17) involved in developing and assessing student research skills. These multiple sources provided evidence that students developed a variety of discipline-specific research skills and that these skills were useful for subsequent studies and especially for employment. Academics indicated that the process of making explicit the development of student research skills led to enhancement of their teaching, helping the academics to clarify major course purposes as well as enabling them to provide more substantial feedback to students than in the past. Academics also indicated that this teaching process changed their understanding of disciplinary research and, for some, even suggested new directions in their research.     

Comparing three South African student cohorts on their attitudes to the rights of working women

This study compares three cohorts (1998–1999, 2005–2006 and 2010) of undergraduate psychology students at a South African university on the level of support for working women (women in paid employment) on various issues considered to be feminist. Cohort 1 (n?=?244), cohort 2 (n?=?311) and cohort 3 (n?=?266) completed an adapted version of a questionnaire used by the Research Group on Women and Work (Kitch, S. L. 1994. “‘We're All in this Alone’: Career Women's Attitudes Toward Feminism.” In Women and Careers: Issues and Challenges, edited by C. W. Konek and S. L. Kitch. London: Sage). The expected liberalisation of attitudes over the cohorts was evident for the females but not for the males: the second male cohort had more conservative attitudes than the first and third male cohorts. While there appeared to be strong overall support for gender equality in work and educational fields, there were equally solid endorsements of the importance of marriage and motherhood for working women. Across the cohorts there were somewhat moderate attitudes on the need for structural change in the family and at work. The implications of the findings are considered.     

Chinese and US Middle-School Science Teachers' Autonomy,Motivation, and Instructional Practices

This study examined Chinese and US middle-school science teachers' perceptions of autonomy support. Previous research has documented the link between teachers' perceptions of autonomy and the use of student-oriented teaching practices for US teachers. But is not clear how the perception of autonomy may differ for teachers from different cultures or more specifically how motivation factors differ across cultures. The survey measured teachers' motivation, perceptions of constraints at work, perceptions of students' motivation, and level of autonomy support for students. Exploratory factor analysis of responses for the combined teacher sample (n?=?201) was carried out for each of the survey assessments. Significance testing for Chinese (n?=?107) and US (n?=?94) teachers revealed significant differences in teachers' motivation and perceptions of constraints at work and no significant differences for perceptions of students' motivation or their level of autonomy support for students. Chinese teachers' perceptions of constraints at work, work motivation, and perceptions of student motivation were found to significantly predict teachers' autonomy support. For the US teachers, teacher motivation was the only significant predictor of teachers' autonomy support. A sub-sample of teachers (n?=?19) was interviewed and results showed that teachers in both countries reported that autonomy was important to their motivation and the quality of science instruction they provided to students. The primary constraints on teaching reported by the US teachers related to materials and laboratory space while the Chinese teachers reported constraints related to the science curriculum and standards.     

The professional student program for educational resilience: Enhancing momentary engagement in classwork

Abstract

The Professional Student Program for Educational Resilience (PROSPER) was designed to increase students’ ability to stay momentarily engaged in classwork, thus promoting educational resilience. Participants (N?=?277, 51% male, 74% Irish) from two low-income schools in Dublin, Ireland (School A n?=?158; School B n?=?119), were assessed using the intervention’s theory of change: (1) change in knowledge of how to stay engaged in classwork, (2) subsequent change in momentary engagement in classwork, and (3) subsequent longer-term change in dispositions for engagement (i.e., tendency to enjoy learning). Qualitative results demonstrated that PROSPER facilitated students’ knowledge, momentary engagement, and teachers’ involvement with students. Quantitative analyses uncovered changes in knowledge and momentary engagement for both the higher and lower ability tracks in School A. The results give refined information on how this universal-school based program increased students’ momentary engagement and supported their educational resilience.     

Topoi and literary interpretation: The effects of a critical reading and writing intervention on high school students’ analytic literary essays

Literary scholars use specific critical lenses called topoi (Fahnestock & Secor, 1991) to read literature and write their interpretations of these texts. Literary topoi are used in the discourse of modern college literature classrooms (Wilder, 2002) and are associated with higher grades in students’ literature classes ( [Wilder, 2002] and [Wilder, 2005] ). However, research shows that high school students are generally unable to justify their literary interpretations (Marshall, 2000). In this study, six high school students were taught a strategy to recognize and use topoi to form an interpretation of literature, and then write an argument to support that interpretation. Three of the students were taught to recognize repeated examples of single patterns of symbolism and imagery that support a theme, i.e., the ubiquity topos. The other three were taught to recognize opposing patterns of symbolism and imagery that support a theme, i.e., the paradox topos. All participants were then taught to form arguments based on the topoi, to utilize direct quotations to back their arguments, and to write “tie-in sentences” that link the quotations to the writers’ arguments. Instruction about these topoi resulted in higher quality argumentative essays that provided more textual evidence to support their literary interpretations.
