Reducing the Socio-Economic Status Achievement Gap at University by Promoting Mastery-Oriented Assessment

In spite of official intentions to reduce inequalities at University, students’ socio-economic status (SES) is still a major determinant of academic success. The literature on the dual function of University suggests that University serves not only an educational function (i.e., to improve students’ learning), but also a selection function (i.e., to compare people, and orient them towards different positions in society). Because current assessment practices focus on the selection more than on the educational function, their characteristics fit better with norms and values shared by dominant high-status groups and may favour high-SES students over low-SES students in terms of performances. A focus on the educational function (i.e., mastery goals), instead, may support low-SES students’ achievement, but empirical evidence is currently lacking. The present research set out to provide such evidence and tested, in two field studies and a randomised field experiment, the hypothesis that focusing on University’s educational function rather than on its selection function may reduce the SES achievement gap. Results showed that a focus on learning, mastery-oriented goals in the assessment process reduced the SES achievement gap at University. For the first time, empirical data support the idea that low-SES students can perform as well as high-SES students if they are led to understand assessment as part of the learning process, a way to reach mastery goals, rather than as a way to compare students to each other and select the best of them, resulting in performance goals. This research thus provides a theoretical framework to understand the differential effects of assessment on the achievement of high and low-SES students, and paves the way toward the implementation of novel, theory-driven interventions to reduce the SES-based achievement gap at University.     

High-school students in university research labs? Implementing an outreach model based on the ‘science as inquiry’ approach

In this study we designed, implemented, and evaluated an outreach programme for high-school biology students rooted in the ‘science as inquiry’ approach. Accordingly, students learn about science from experts in the field, as well as through in-class exposure to the history and philosophy of science. Our sample consisted of 11th graders (n?=?497), ages 16–17, attending advanced biology classes. Our goal was to determine whether this programme had a significant effect on students’ understanding of the ‘nature of science’ (NOS) and on their attitudes towards science. Using a controlled pre-post research design, we asked participants to complete a Likert-like questionnaire. Also, we conducted post-programme semi-structured interviews with 35 of the participants. Results show that completion of the programme significantly enhanced participants’ NOS understanding and improved their attitudes towards science. Participants expressed a deep level of NOS understanding and explicitly stated that the field visits to experts’ labs had changed their attitude towards science. We believe that our outreach programme can be adapted for teaching other sciences and for societies worldwide, as long as there is access to university laboratories and researchers willing to interact with young citizens and potential future scientists.     

Social mobility of ethnic minority students in Laos

Idealistically speaking, schools are engines for upward social mobility. Education for ethnic minorities in Laos was set up to achieve nationalist, political, economic and sociocultural goals of ‘equity’ and ‘equality’. It was hoped that education would shift ethnic minorities from a lifestyle based on superstitious beliefs to a modern one, so that they could participate and enjoy ‘equality’ through educational equity. The purpose of this paper is to provide a case study of how equality as a promise in education has impacted on students’ upward mobility, particularly the political discourse of the ‘big man’. This paper explores social mobility provided by national education for ethnic minorities through boarding schooling. It finds that such education has yet to reposition ethnic minorities into the ethnic Lao sociocultural hierarchy. As a result, regardless of their educational success, students are still ranked as ‘ethnic minorities’ and as being ‘poor’ in the eyes of urban students, middle class and rich students, and the ethnic Lao elite.     

Effective field trips in nature: the interplay between novelty and learning

Educational field trips are common practice in environmental education and education for sustainable development, well recognised by researchers for their potential to achieve cognitive and affective educational outcomes. One of the factors that influences learning during field trips is their novelty. The current study focuses on the interplay between novelty, preparation and environmental learning outcomes of 5th and 6th grade students during a typical field trip in Flanders. Our dependent variables are Inclusion of Nature in the Self, the two major ecological values Preservation and Utilisation and ecosystem knowledge. The sample includes 484 students (10–12 years old) and their 24 teachers. Key questions addressed are: (1) What is learned during the field trip? (2) What is the level of novelty for students during a field trip? (3) How does the novelty effect relate to learning? Results show that participation in the field trip leads to a substantial increase in ecosystem knowledge, but fails in reaching the affective goals set out by the field trip organisers. Our results furthermore provide support for the hypothesised non-linear relationship between novelty and knowledge gain, showing that while a little novelty is positive, too much novelty can stand in the way of learning.     

What Do Secondary Students Really Learn during Investigations with Living Animals? Parameters for Effective Learning with Social Insects

Exemplary for social insects, Temnothorax ants allow for various hands-on investigations in biology classes. The aim of this study was to provide a quantitative and qualitative analysis of secondary school students’ learning achievement after teaching units with ants lasting between one and six weeks. The questionnaires included transfer and factual knowledge tasks divided into eight fields of knowledge. Students (N = 459) from 22 classes participated in the study and received different treatments: The experimental group (n = 366) started their investigations by initial observation using stereo microscopes, while the control group (n = 93) conducted ant research without this introductory teaching unit. We investigated the influence of class level, gender and time period of participation on knowledge acquisition. Independent of class level, factual learning achievement was observed for all fields of knowledge except ecology. We did not find a positive correlation between time period of participation and basic ant knowledge acquisition. The findings suggest that ant research may be implemented within the framework of a progressive curriculum for all secondary school students. However, attentive and detailed observation of ant colonies with stereo microscopes and continuous repetition of technical terms seem to be inevitable preconditions for learning achievement.     

How do Detergents Work? A Qualitative Assay to Measure Amylase Activity

We present a practical activity focusing on two main goals: to give learners the opportunity to experience how the scientific method works and to increase their knowledge about enzymes in everyday situations. The exercise consists of determining the amylase activity of commercial detergents. The methodology is based on a qualitative assay using a colorimetric process. Quantitative results are also obtained by measuring the halo formed. This activity is suitable for and adaptable to learners at different levels of education: primary school, secondary education or even for pre-service teachers, which is the group the version described in this paper was intended for. This laboratory activity was designed to include the scientific method as a learning outcome. This was especially important in pre-service teachers, as increasing scientific literacy is one of the primary goals of science education. Through the activity, students also learn about micro-organisms and their applications in their daily lives, which is one of the tenets of Science–Technology–Society–Environment programs. A case study was conducted with a group of learners made up of 75 pre-service teachers from Universitat Rovira i Virgili in Tarragona, in order to verify whether this lab activity is well designed and can be satisfactorily implemented.     

Design and performance frameworks for constructing problem-solving simulations

Rapid advancements in hardware, software, and connectivity are helping to shorten the times needed to develop computer simulations for science education. These advancements, however, have not been accompanied by corresponding theories of how best to design and use these technologies for teaching, learning, and testing. Such design frameworks ideally would be guided less by the strengths/limitations of the presentation media and more by cognitive analyses detailing the goals of the tasks, the needs and abilities of students, and the resulting decision outcomes needed by different audiences. This article describes a problem-solving environment and associated theoretical framework for investigating how students select and use strategies as they solve complex science problems. A framework is first described for designing on-line problem spaces that highlights issues of content, scale, cognitive complexity, and constraints. While this framework was originally designed for medical education, it has proven robust and has been successfully applied to learning environments from elementary school through medical school. Next, a similar framework is detailed for collecting student performance and progress data that can provide evidence of students' strategic thinking and that could potentially be used to accelerate student progress. Finally, experimental validation data are presented that link strategy selection and use with other metrics of scientific reasoning and student achievement.     

Parents’ assessment of circadian preference in elementary school-aged children: Validity and relations to educational outcomes

Meta-analyses suggest that morning-oriented students obtain better school grades than evening-oriented students. This finding has generally been found for students in high school using self-report data for the assessment of circadian preference. Two studies (N = 2718/192) investigated whether these findings generalize across samples (i.e. elementary school-aged students) and methods (i.e. parent reports). These studies also explored whether the relation between circadian preference and school achievement could be explained within an expectancy-value framework. To this end, the Lark-Owl Chronotype Indicator (LOCI) was modified to obtain parents’ evaluations of their children’s circadian preference, while students completed a battery of assessments designed to explore the test-criterion evidence. Structural equation modeling and correlational analyses revealed: (1) morning and evening orientation were two separable factors of children’s circadian preference; (2) correlations with behavioral (e.g. sleep and eating times) and psychological (e.g. cognitive ability) data supported the test-criterion validity of both factors; (3) morning orientation was positively related to school achievement and (4) consistent with an expectancy-value framework this relation was mediated by children’s academic self-concept (ASC). These findings have important research and policy implications for considering circadian preference in the schooling of elementary students.     

Metacognitive inquiry activities for instructing the central dogma concept: ‘button code’ and ‘beaded bracelet making’

ABSTRACT

The central dogma of biology is difficult to learn because its microscopic processes cannot be visualized. This study aimed to devise two inquiry activities: ‘Button Code’ and ‘Beaded Bracelet Making,’ involving the concepts of DNA replication and protein synthesis based on the Metacognitive Learning Cycle (MLC) for students, and to explore the effectiveness of concept learning of the central dogma, how students’ metacognition may be expressed, and students’ perceptions of their inquiry performance. We developed a ‘Concept journal’ including metacognitive scaffolds, and employed the ‘Central Dogma Achievement Test’ as a tool for the above purpose. A total of 18 junior high school students participated in this inquiry course instructed by two of the authors. The results showed that students’ achievement performance was significantly improved on the whole, the students’ metacognition was expressed during the process of inquiry with scaffolding, and most students gave positive responses about their learning performance. According to the results, this inquiry course could develop students’ comprehension of the central dogma concept, and give students opportunities to practice metacognition that might lead to effective learning in inquiry activities. The implications and expandability of this course are discussed.     

The effect of using a case study on the academic achievement of students in learning about the topic of ‘Vitamins’

This study investigates the impact of the Case-Based Learning (CBL) method for the topic of ‘B6, B9 and B12 Vitamins’ on students’ academic achievement in a biochemistry course for an associate degree level in health. To this end, a case study with the title ‘The Reasons for Depression: Do We Know What They Are?’ was developed and implemented. The study had a one-group pre-test and post-test research design. The ‘Vitamins’ Achievement Test’ (VAT) and a Structured Interview Form were used as data collection tools. First-year students of Medical Laboratory Techniques at the Ahmet Erdogan Vocational School of Health Services at Bulent Ecevit University (N = 34) who were aged between18 and 20 made up the study group. The VAT and the Structured Interview Form were analysed using content analysis and the paired-samples t-test was used for the VAT. The results indicated that the frequency of students’ responses in the ‘clear understanding’ category improved in the VAT post-test and it was concluded that there was a significant positive difference in the post-test scores of students. The results of the structured interview indicated that most of the students had positive opinions about the method, material and case study.     

半翻转生物化学教学模式对学生学业成绩和自我认知的影响

“以学生为中心”的翻转课堂教学模式可以提高学生的学业成绩、改善认知和培养创新能力等,但对知识掌握的整体性、系统化和育人方面存在明显的不足;传统教学“以教师为中心”的教学理念却有着知识学习的系统化和育人方面的独特优势。我们结合了翻转课堂和传统教学各自的优点,在山东大学齐鲁医学院2020级口腔医学、药学和预防医学专业的生物化学教学中,引入了翻转课堂与传统教学相结合的半翻转课堂的教学模式,并以2019级的传统教学模式作为对照,对学生的学业成绩和自我认知情况的改善进行统计学分析。结果表明,采用半翻转课堂教学的学生成绩优于传统式教学(P<0.01);学生的自我认知能力在半翻转课堂教学实施前后有显著改善(P<0.01或P<0.05);该研究为医学院校的相关教学和研究工作提供参考。     

How fieldwork-oriented biology teachers establish formal outdoor education practices

ABSTRACT

Fieldwork is an important part of biology as well as science and biology education. However, teachers perceive several reasons for the limited use of fieldwork in schools. Further, outdoor education is often organised as a single fieldtrip guided by outdoor educators, and little research has been done on fieldwork as a regular part of formal biology education. This case study explores three secondary-school biology teachers who untypically use outdoor education as a major part of their ecology courses for 8^th grade students (median age 14). Berger and Luckmann’s theory of the process of institutionalization as a theoretical background is used to interpret the pedagogical and organizational choices of the case study teachers. Analysis of the interviews of the selected three teachers revealed pedagogical and organizational means through which outdoor teaching is institutionalized into a regular activity in biology lessons. The teachers considered regularity, assessment practices and the school curriculum as major tools to legitimate outdoor learning as a formal schoolwork and foster successful learning. However, they also emphasised students’ freedom during outdoor activities. The findings are discussed in terms of how the teachers succeeded in combining the institutional order of formal schooling with students’ freedom in nature.     

Racial/Ethnic Differences in Effects of Welfare Policies on Early School Readiness and Later Achievement

This study examined whether the effects of employment-based policies on children's math and reading achievement differed for African American, Latino and Caucasian children of welfare receiving parents, and if so, why. Two kinds of employment policies were examined: education-first programs with an emphasis on adult education and job training; and work-first programs with an emphasis on immediate employment. With data from two- and five-year follow-ups in four experimental demonstrations in Grand Rapids, Michigan (N = 591) and Riverside County, California (N = 629), there was evidence of small positive effects of the Grand Rapids and Riverside education-first programs on African American and Latino children's school readiness and math scores. An opposite pattern of effects emerged among Caucasian children. In one of the two sites, we found that Latino parents' higher levels of goals for pursuing their own education appeared to explain why their children benefited to a greater degree from the program than their Caucasian counterparts.     

A Meta-Analysis of Self-Reported Achievement Goals and Nonself-Report Performance across Three Achievement Domains (Work,Sports, and Education)

During the past three decades, the achievement goal approach to achievement motivation has emerged as an influential area of research, and is dedicated to understanding the reasons behind the individual’s drive to achieve competence and performance. However, the current literature on achievement goals is segmented rather than integrated. That is, citations across the three major and distinct achievement domains (work, education, and sports) are more the exception than the rule and similarities and differences between findings for the different achievement domains have yet to be tested. The purpose of the present study was to examine the relationships between self-reported achievement goals and nonself-report performance through meta-analysis, and the moderating potential of achievement domain. Identifying achievement domain as moderator improves our understanding to which contexts we can (not) generalize conclusions to, it helps to understand seemingly inconsistent findings, and opens avenues for future research on the underlying processes. Because the achievement goal (AG) measure used in a study is partially confounded with achievement domain, we examined the moderating role of this variable as well. Our findings suggest that – overall – approach goals (either mastery or performance) were associated positively with performance attainment, whereas avoidance goals (either mastery or performance) were associated negatively with performance attainment. These relationships were moderated by achievement domain. For example, relative to the education or work domain, in the sports domain, we did not observe negative correlations between avoidance goals and performance. The absence of statistical moderation due to AG measure suggests that the observed moderation of achievement domain cannot be explained by the AG measure utilized. We suggest further steps to integrate the achievement goal literature, and accordingly, to broaden and deepen understanding of performance attainment in competence-relevant settings, including the workplace, the sports field, and the classroom.

Cell sociology and the problem of automation in the development of pluricellular animals

The principles of automation (automatism and programming) in the unfolding of spatio-temporal patterns during animal development are deduced from experimental data reconsidered from the point of view of cell sociology. The developmental programme in the egg is not part of the genetic information but a part of the cytoplasmic information. Throughout development cells store extra-cellular information released by their neighbours in the form of cytoplasmic information. Successive determinations cannot be considered as successive reprogrammings of cells: each one consists of a selection of one specific programme from the total information previously stored. This programme specifies cell interactions in the determined population as a whole; it is very imprecise and is progressively completed during the course of further differentiation by information released by neighbouring cell populations. Complicated patterns may emerge from only two homogeneous populations involved in distinct differentiation pathways and confronting each other. Consequently the egg developmental programme provides gene effectors and specific physico-chemical conditions necessary for the starting of at least two distinct differentation pathways. Experimental data suggest that there are two components in this programme. One is a molecular machinery which starts at fertilization in the whole cytoplasm. It yields two programmes of differentiation, typically first an endodermal and then an ectodermal one. The other component of the egg developmental programme, which does not require specific information, allows the interception of the first (endodermal) programme. The application of informatics to developmental automatism is discussed in the latter part of the paper.     

Effect of a Multi-Dimensional Intervention Programme on the Motivation of Physical Education Students

This research study purports to verify the effect produced on the motivation of physical education students of a multi-dimensional programme in dance teaching sessions. This programme incorporates the application of teaching skills directed towards supporting the needs of autonomy, competence and relatedness. A quasi-experimental design was carried out with two natural groups of 4^th year Secondary Education students - control and experimental -, delivering 12 dance teaching sessions. A prior training programme was carried out with the teacher in the experimental group to support these needs. An initial and final measurement was taken in both groups and the results revealed that the students from the experimental group showed an increase of the perception of autonomy and, in general, of the level of self-determination towards the curricular content of corporal expression focused on dance in physical education. To this end, we highlight the programme''s usefulness in increasing the students'' motivation towards this content, which is so complicated for teachers of this area to develop.     

Social jetlag,academic achievement and cognitive performance: Understanding gender/sex differences

Adolescents in high school suffer from circadian misalignment, undersleeping on weekdays and oversleeping on weekends. Since high schools usually impose early schedules, adolescents suffer from permanent social jetlag (SJL) and thus are a suitable population to study the effects of SJL on both academic and cognitive performance. In this study, 796 adolescents aged 12–16 years reported information about their sleep habits, morningness–eveningness (M–E), cognitive abilities and grade point average (GPA). Time in bed on both weekdays and weekends was not related to cognitive abilities, and only time in bed on weekdays was related to academic achievement. SJL was negatively related to academic achievement, cognitive abilities (except for vocabulary and verbal fluency abilities) and general cognitive ability (g), whereas M–E was slightly positively related to academic achievement and marginally negatively related to inductive reasoning. Results separated by sex/gender indicated that SJL may be more detrimental to girls’ performance, as it was negatively related to a greater number of cognitive abilities and GPA.     

Improving Upper Elementary Students’ Humane Attitudes and Prosocial Behaviors through an In-class Humane Education Program

Humane education is a long-standing field of education that endeavors to nurture kindness, compassion, and concern for nonhuman animals, people, and the environment. Despite its long history, however, few randomized control studies have evaluated its effectiveness to promote the development of relevant outcomes. The current study sought to address this dearth by investigating the effects of a humane education program on not only participating students’ attitudes, but also their behaviors. Classes of under-served, fourth-grade students in two major US cities were randomly assigned to participate in either a school-based humane education program or a chess club (the control group); all students participated in their respective activity during the same period once a week for 11 weeks. Data were collected on the attitudes (n = 236) and behaviors (n = 167) of participating students exactly one week before and exactly one week after these programs were conducted. Students self-reported their attitudes about the treatment of animals and the environment via the Intermediate Attitude Scale. Teachers rated each students’ prosocial and disruptive behaviors through sub-scales of the Teacher Observation of Classroom Adaptation– Checklist. Nested multilevel models of change found that the development of prosocial behaviors and self-reported attitudes significantly interacted with group assignment: Students who participated in the humane education program showed stronger growth in both of these outcomes compared with students in the control group. Changes in disruptive behaviors, how-ever, were not found to differ between groups. The results support the effectiveness of a humane education program to teach a relatively large and diverse group of upper elementary students to learn about animal welfare issues and to improve their prosocial behaviors. Effects appeared strongest on attitudes; behavioral effects were found to be largely limited to behaviors directly addressed by the humane education program.     

Trends in Biological Education-An International Review

We examined selected situational emotions (interest, well-being and anxiety) experienced by 291 secondary school tenth graders during a hands-on gene technology lesson. Two different instruction groups (I-1, I-2) participated in the same teaching unit, in which four basic gene technology experiments were performed. Using a modified ‘constructivist teaching sequence’, a teacher confronted group I-2 with the alternative conceptions of their peers regarding central issues and processes of gene technology in addition to providing the scientific concepts. The pupils within the I-2 group scored higher in the positive emotions of interest and well-being. The negative emotion anxiety was almost absent in both instruction groups. Furthermore, our results indicate a potential influence of interest and well-being upon learning success. Pupils who felt fine and worked with interest in the experimental lessons scored significantly higher on the cognitive achievement test. Eliciting pupils’ alternative conceptions and using them in a wide variety of teaching contents is therefore advisable. By doing so, teachers could help create a classroom environment where pupils feel safe and confident. Also, a pupil’s interest regarding the choice of material needs to be taken into account if positive emotions need strengthening and the learning achievement needs improvement.
