Seventh grade students' mental models of the greenhouse effect

This constructivist study investigates 225 student drawings and explanations from three different schools in the midwest in the US, to identify seventh grade students' mental models of the greenhouse effect. Five distinct mental models were derived from an inductive analysis of the content of the students' drawings and explanations: Model 1, a ‘greenhouse’ for growing plants; Model 2, greenhouse gases cause ozone depletion or formation, causing the Earth to warm; Model 3, greenhouse gases, but no heating mechanism, simply gases in the atmosphere; Model 4, greenhouse gases ‘trap’ the sun's rays, heating the Earth; and Model 5, the sun's rays are ‘bounced’ or reflected back and forth between the Earth's surface and greenhouse gases, heating the Earth. Science textbooks are critiqued in light of the students' mental models and curricular and instructional implications are explored.     

Marine environmental protection knowledge,attitudes, behaviors,and curricular involvement of Taiwanese primary school students in senior grades

In recent years, rapid changes in the Earth's climate and environment have influenced our lives greatly. The ocean occupies 70% of the Earth's surface and is intimately related to the regulation of climate, fostering of life, and also to social economy, as well as sports and leisure. Students in the senior years of primary education are in a phase of developing value systems. Concurrently, these students are also constantly using the Earth's resources. More importantly, they will play leading roles in the next generation. From the perspective of education, the learning status of student's cognition, attitudes, and behaviors regarding protection of the marine environment must be understood more clearly to avoid future mismanagement of marine environmental problems on the part of these students. Hence, this study uses correlative, regressive, and path statistical analysis to examine data collected from questionnaires. Results show that student knowledge of and attitudes toward marine environmental protection do not have significant influences on behaviors; however, student's marine environmental protection knowledge, attitudes, and behaviors are all within the medium to high range. Because of relatively low student curricular involvement, and because involvement has no correlation with knowledge performance, this study infers that school curricula are not the main sources of student information and attitudes regarding marine environmental protection. Rather, building student attitudes toward marine environmental protection by increasing their involvement in field trips indirectly influences behaviors that are protective of the marine environment. Such an approach is comparatively more effective and can serve as a reference for modifying the implementation methods of marine protection curricula.     

Students choosing colleges: Understanding the matriculation decision at a highly selective private institution

This paper provides an econometric analysis of the matriculation decisions made by students accepted to Williams College, one of the nation's most highly selective colleges and universities. Using data for the Williams classes of 2008 through 2012 to estimate a yield model, we find that—conditional on the student applying to and being accepted by Williams—applicant quality as measured by standardized tests, high school GPA and the like, the net price a particular student faces (the sticker price minus institutional financial aid), the applicant's race and geographic origin, plus the student's artistic, athletic and academic interests, are strong predictors of whether or not the student will matriculate.     

Learning molecular behaviour may improve student explanatory models of the greenhouse effect

We assessed undergraduates’ representations of the greenhouse effect, based on student-generated concept sketches, before and after a 30-min constructivist lesson. Principal component analysis of features in student sketches revealed seven distinct and coherent explanatory models including a new Molecular Details model. After the lesson, which described the invisible molecular behaviour of gases, this group (n = 164) produced significantly more expert-like representations of the greenhouse effect, and included fewer novice ideas. The key behaviour that greenhouse gases emit radiation in random directions is new to most students and directly counters common explanations involving reflection and ‘trapping’ of radiation in the atmosphere. Thus, learning molecular behaviour of greenhouse gases may help students replace non-expert explanatory models. This Molecular Details model has not been previously identified, and is unlikely to have emerged from human evaluation of student sketches alone. When teaching the greenhouse effect, we propose that interventions explicitly incorporate greenhouse gas behaviour.     

A Model of Homework's Influence on the Performance Evaluations of Elementary School Students

This study was the first to test a model of the influence of homework on classroom performance using a sample of elementary school students. A total of 28 teachers in Grades 2 and 4 took part in the study, along with 428 students and parents. The authors used structural equation modeling to examine relationships among variables. Student norms were positively related to the elimination of distractions from homework by parents. Positive student norms, higher student ability, and positive parent attitudes toward homework were all related to greater parent facilitation. Student's attitude toward homework was unrelated to home and community factors but was related positively to parent attitudes toward homework. Classroom grades were unrelated to student's attitude toward homework but were predicted by how much homework the student completed (even after the use of homework in grading was controlled), by student ability, and by the amount of parent facilitation. More generally, parent facilitation was an important mediator of the relation between student norms, student ability, and parent attitudes toward homework, and the outcome of classroom grades.     

Using the PSSC Laboratory Course in the First Year of College

Summaries

English

In the physical sciences, laboratory instruction has always taken place alongside classroom instruction. Undergraduate physics education has been a mixture of theoretical and experimental instruction, where the theoretical part plays the dominant role. The freshman laboratory holds a prominent role because it is the place where the student acquires the skills and attitudes that will help him understand the advanced subjects.

The freshman laboratory is particularly important in countrieswhere the student's instruction in experimentation is practically non‐existent at the secondary‐school level. In these cases, where the freshman laboratory is the student's first exposure to experimental science, we are particularly concerned that together with learning the ‘right’ things the student should develop the ‘right’ attitudes; as the ‘right’ attitudes can encourage curiosity and motivation for lifelong learning.     

A reaction to the commentaries

In this chapter, conclusions are drawn and implications are suggested. Of the non-cognitive variables included in the study, the students’ Priorities were the most important in predicting GPA. In general, non-cognitive variables provided important information on admissions. Furthermore, explicit conceptual models, analyzed with relatively sophisticated statistical techniques, are needed to further our understanding of variables directly and indirectly related to college success.     

The State of the Literature on Student Evaluations of Teaching and an Exploratory Analysis of Written Comments: Who Benefits Most?

The purpose of this exploratory analysis is to review the state of the literature on student evaluations (SEs) of teaching and examine to what extent an instructor's race/ethnicity influences student's qualitative comments. Also, does the intersection of race and gender influence student's qualitative comments on SEs? Utilizing an online survey distributed among various organizational listserv in the discipline of Political Science, this study highlights written comments received on SEs by faculty generally. Additionally, we hope to contribute findings that support how negative comments may affect faculty of color and women.     

Facial micro-expression states as an indicator for conceptual change in students' understanding of air pressure and boiling points

Utilizing facial recognition technology, the current study has attempted to predict the likelihood of student conceptual change with decision tree models based on the facial micro-expression states (FMES) students exhibited when they experience conceptual conflict. While conceptual change through conceptual conflicts in science education is a well-studied field, there is little research done on conceptual change through conceptual conflict in terms of students' facial expressions. As facial expressions are one of the most direct and immediate responses one can get during instruction and that facial expressions are often representations student's emotions, a link between students' FMES and learning was explored. Facial data was collected from 90 tenth graders. Only data from the 72 students who made incorrect predictions were analyzed in this study. The concept taught was the relationship between boiling point and air pressure. Through facial recognition software analysis and decision tree models, the current study found Surprised, Sad and Disgusted to be key FMES that could be used to predict student conceptual change in a conceptual conflict-based scenario.     

“Areas of Instruction”—A Tool for Assessing the Quality of Instructional Situations

A model for analysing the nature of the dyadic teacher–student interplay in instructional situations including one teacher and one student is described. The “teacher” may be a regular teacher, a parent, or any other person who is in the position of teacher. The “student” may be a student of any age. The model may discern (a) if the teacher merely asks for information preknown to the teacher and the teacher evaluates the student's answer according to the teacher's preknowledge, (b) if the teacher asks for information preknown to the teacher, the teacher then scaffolds the student's learning by giving clues to the correct answer and then evaluates the answer according to the teacher's preknowledge, or (c) the teacher asks for information not preknown to her/him and the teacher is genuinely interested in the student's answer. This last scenario (c) is thought to give optimal conditions for cognitive development for the student.     

Teacher attributions of student failure and teacher behavior toward the failing student

The aim of this study was to examine the relation between teacher attributions of student school failure and teacher behavior toward the failing student. A structural equation model was proposed and its ability to fit the data was tested. It was found that teachers tend to behave in ways that indicate more pity and less anger when they attribute a student's low achievement to her or his low abilities, whereas they express more anger when attributing low achievement to the student's low effort. In contrast to previous research that argues in favor of anger as a high ability cue, this study has found that the presence of anger was associated with a teacher tendency to give‐up efforts to help the student improve. This giving‐up behavior was negatively related to the tendency of the teachers to accept some responsibility for the student failure. © 2002 Wiley Periodicals, Inc.     

Grade Placement of High-School Biology

Abstract

Using 35 elementary schools (3,350 fourth and sixth grade students), 10 secondary schools (3,613 eight and eleventh grade students), and 1,145 teachers, this study presents data summarizing the relationships between student' perceptions of "verified" principal competencies and selected school climate indices and outcome variables. The results indicated that there is a general tendency for positive teacher attitudes towards various dimensions of the school and working environment and higher student standardized achievement test performance to be associated with students' reports of a low frequency of interaction with die principal. A student "independence factor" was hypothesized to account for these results, with the implication being that principal/student interaction is minimized in schools where teacher and student attitudes are positive and student achievement is high. In addition, effective principal performance in dealing with student misbehavior was highly and positively associated with school average daily attendance at the secondary level. Supplementary analyses indicated that teacher and student attitudes "mediating" the school environment were relatively independent for both elementary and secondary samples. General support was found for higher correlations between student assessments of principal competencies and school environment measures than with student performance measures.     

Teachers’ academic appraisals and referral decisions: The effect of sharing health information when diabetes is present

Two prior studies showed that giving teachers more information about a student's illness led them to make better attributions about that student's classroom problems and better classroom accommodations. In this study, 235 teachers appraised academic competence and judged whether to seek help or make a referral for a hypothetical student with type 1 diabetes mellitus (T1DM). Teachers received one of five levels comprising increasing disease disclosure and classroom‐relevant information about T1DM. Contrary to prior studies, teachers in this study who were given a student's T1DM diagnosis and details about T1DM's classroom risks failed to make better judgments about the student's academic skill levels or to award more accurate grades. Instead, teachers seemed swayed by this student's apparently careless and inconsistent schoolwork, which was presumably disease related. Likewise, better‐informed teachers were no better at selecting accommodations. However, once it was disclosed that the hypothetical student had T1DM, most teachers seemed knowledgeable about the most appropriate potential Individuals With Disabilities Education Improvement Act category for service delivery. Regarding practice issues, school psychologists were rarely selected as a first choice for consultation, and the more information teachers were provided with about T1DM and the student's disease status, the less likely they were to select a school psychologist as a consultant.     

Innovating science teaching with a transformative learning model

Abstract

This exploratory study aimed to describe the impact of the ‘Science in Family project’, as a transformative learning model for science teachers trying to improve student’s attitudes toward STEM subjects. This study took place in a public elementary school in Monterrey, Mexico, which has been developing this project for more than thirteen years with students from 4th, 5th and 6th grade. We used participant observation and interviews with four families whose children are students of this elementary school, and with one family whose sons were students of this school some years ago. Results showed that there is a relationship between positive attitudes towards science in students who were exposed to transformative learning models of teaching. Two of the participants took steps to follow science related careers. This study helps to illuminate the extent to which teacher education models influence students’ attitudes and how positive attitudes to science are influenced by the use of learning by doing projects.     

“A Fantasy of Untouchable Fullness”: Melancholia and Resistance to Educational Transformation

The progressive language of growth and development that informs our shared ideal of the educated subject also informs the curricular structure of schooling, in which new learning builds upon established knowledge and students' development depends upon their desire to take on those identities associated with various achievements of knowledge. Each re‐creation of the student's identity requires a new production of the student's former identity as an uneducated self — a negative statement of the self‐overcome, fashioned in the language of the curriculum. But what of those objects of attachment or aspects of the child's identity that can neither be integrated in the student's educated identity nor accounted for as a recognizable lost object of childhood? In this essay James Stillwaggon argues that considering the student subject in terms of its melancholic attachments offers some alternatives to thinking of student identity primarily in terms of its progressive learning function. Julia Kristeva's treatment of melancholia as “asymbolia,” or against the representational function of language, is especially significant to this discussion, as it highlights the melancholic's resistance to the most basic educational purpose, namely the further engagement of the subject in language.     

The influences of inductive instruction and resources on students' attitudes toward reading: evidence from PISA 2009

The declining trend in the positive reading attitude of students' has concerned scholars. This paper aims to apply a 3-level hierarchical linear model to analyse how inductive instruction and resources influence both students' positive and negative attitudes towards reading. Approximately 470,000 15-year-old students, and their school principals, from 65 countries completed a questionnaire, which was designed by the Programme for International Student Assessment (PISA). In line with previous research, gender, the student–teacher relationship, online academic searches, and reading habits are correlated with both positive and negative reading attitudes. Multilevel results show that reading attitudes improved when a school provides a context in which inductive instruction has been enforced. The natural log value of gross domestic product (GDP) per capita in a country is statistically significantly negative when associated with a student's positive and negative reading attitudes. Further, in a country with largely unqualified teachers, school-level inductive teaching lowers the negative attitude.     

Evolving patterns of working: do they matter?

We consider how changing attitudes to computer use may alter the habits of students in the use of location and times of the day. We discover for one community the extent to which they absent themselves from the physical university and see some trends. We suggest that this is a deep change of habit, influenced by the ‘digital generation’, and seek qualitative results on what determines the modern student's keyboard behaviour. We present early evidence that, while students are indeed absenting themselves from formal computer facilities, some understanding of the benefits of the physical university remains intact.     

Study skills in anatomy and physiology: Is there a difference?

Many factors influence the way individual students study, including but not limited to: previous coursework, attitudes toward the class (motivation, intimidation, risk, etc.), metacognition, and work schedules. However, little of this research has involved medical students. The present article asks the question, “Do individual medical students study differently for different classes?” Study skills surveys were given to United States medical students at an allopathic medical school and an osteopathic medical school. Students were surveyed near the end of their first year gross anatomy course and again near the end of their first year physiology course. Survey items included Likert scale and open‐ended questions about study habits and basic demographic information. The survey responses were correlated with each student's final grade percentages in the courses. Analysis revealed that the four most common study habits were reviewing lecture notes, taking practice examinations, completing learning exercises, and making drawings and diagrams. The two surveys (anatomy and physiology) from each individual were also compared to see if students reported different study habits in anatomy versus physiology. A negative correlation was found between changing study habits between courses and final anatomy grade percentages. Additional analyses suggest that those students who do change their study habits between courses are increasing the number of study strategies that they attempt. This increase in the number of study strategies attempted may not allow the student to reach the same depth of understanding as their colleagues who utilize fewer strategies.

The unintentional consequences of science teaching

In this study the possibility that variations in the nature and extent to which individual students interact with the teacher may, in fact, produce unintentional consequences is examined. A battery of tests measuring pupil cognitive, motivational, and personality characteristics was administered to 150 students in four classes prior to instruction. The nature and frequency of each student's interaction in a sample of five lessons was then determined. Canonical analysis was used to determine how these antecedent pupil characteristics and communication pattern variables were related to science achievement, attitudes towards science and socio-metric measures. Four independent relationships were found and appear to represent “syndromes” some of which lead to undesirable consequences if allowed to run their full course.
