The effects of an active learning intervention in biology on college students’ classroom motivational climate perceptions,motivation, and achievement

This study examined differences in students’ classroom motivational climate perceptions and motivational beliefs between those enrolled in undergraduate Biology courses that implemented an innovative, active learning intervention and those enrolled in traditional Biology courses (control group). This study also sought to determine whether students’ classroom motivational climate perceptions and motivational beliefs mediated the effect of the intervention on course grades. Participants were 962 college students attending a large US public university. Students self-selected into one of the biology courses were randomly assigned to the intervention or control group. Multiple regression analyses indicated that students receiving the intervention reported greater instructor support, a perception of higher expectations for understanding (academic press), and a greater feeling that the course was interesting (situational interest). They also held higher self-efficacy and value for their biology course at completion compared to their counterparts in traditional biology classrooms. Moreover, mediation analyses indicated that the effect of the intervention on course grades was better explained through students’ classroom motivational climate perceptions and motivational beliefs. Results gained from this intervention may be useful to other campuses interested in enhancing student motivation and success even when faced with large enrolments and minimal faculty and staff support.     

Direct transformation of variational problems into Cauchy systems—II. scalar-semi-quadratic case

This series of papers addresses three interrelated problems: the solution of a variational problem, the solution of integral equations, and the solution of an initial valued system of integrodifferential equations. It will be shown that a large class of variational problems requires the solution of a nonlinear integral equation. It has also been shown that the solution of a nonlinear integral equation is identical to the solution of a Cauchy system. In this paper, we by-pass the nonlinear integral equations and show that the minimization problems directly imply a solution of the Cauchy system. This second paper in the series looks at semi-quadratic functional and scalar functions.     

The impact of badminton on health markers in untrained females

The purpose of the study was to examine the health effects of 8 weeks of recreational badminton in untrained women. Participants were matched for maximal oxygen uptake (V?O_2max) and body fat percentage and assigned to either a badminton (n = 14), running (n = 14) or control group (n = 8). Assessments were conducted pre- and post-intervention with physiological, anthropometric, motivation to exercise and physical self-esteem data collected. Post-intervention, V?O_2max increased (P < 0.05) by 16% and 14% in the badminton and running groups, respectively, and time to exhaustion increased (P < 0.05) by 19% for both interventions. Maximal power output was increased (P < 0.05) by 13% in the badminton group only. Blood pressure, resting heart rate and heart rate during submaximal running were lower (P < 0.05) in both interventions. Perceptions of physical conditioning increased (P < 0.05) in both interventions. There were increases (P < 0.05) in enjoyment and ill health motives in the running group only, whilst affiliation motives were higher (P < 0.05) for the badminton group only. Findings suggest that badminton should be considered a strategy to improving the health and well-being of untrained females who are currently not meeting physical activity guidelines.     

How to Desire Differently: Home Education as a Heterotopia

This article explores the co‐existence of, and relationship between, alternative education in the form of home education and mainstream schooling. Home education is conceptually subordinate to schooling, relying on schooling for its status as alternative, but also being tied to schooling through the dominant discourse that forms our understandings of education. Practitioners and other defenders frequently justify home education by running an implicit or explicit comparison with school; a comparison which expresses the desire to do ‘better’ than school whilst simultaneously encompassing the desire to do things differently. These twin aims, however, are not easy to reconcile, meaning that the challenge to schooling and the submission to norms and beliefs that underlie schooling are frequently inseparable. This article explores the trajectories of ‘better than’ and ‘different from’ school as representing ideas of utopia and heterotopia respectively. In particular I consider Foucault's notion of the heterotopia as a means of approaching the relationship between school and other forms of education. Whilst it will be argued that, according to Derrida's ideas of discursive deconstruction, alternative education has to be expressed through (and is therefore limited by) the dominant educational discourse, it will also be suggested that employing the idea of the heterotopia is a strategy which can help us explore the alternative in education.     

The contribution of childhood emotional abuse to teen dating violence among child protective services-involved youth

ObjectiveFor child protective services (CPS) youth who may have experienced more than one form of maltreatment, the unique contribution of emotional abuse may be over-looked when other forms are more salient and more clearly outside of accepted social norms for parenting. This study considers the unique predictive value of childhood emotional abuse for understanding adolescent post-traumatic stress disorder (PTSD) symptomatology and dating violence. Further, PTSD symptomatology is assessed as an explanatory bridge in the emotional abuse—teen dating violence link.MethodsA random sample of 402 youth from the active caseload of a large urban CPS catchment area participated as part of a larger longitudinal study on adolescent health behaviors. Mid-adolescent youth across types of CPS status were targeted. CPS youth reported on lifetime maltreatment experiences, PTSD symptomatology, and past year dating experiences, using published scales.ResultsOver 85% of CPS youth had begun dating. For dating youth, some level of dating violence was common: over half of females (63–67%) and nearly half of males (44–49%). Taking into account other forms of maltreatment, emotional abuse emerged as a significant predictor of both PTSD symptomatology and dating violence among males and females. PTSD symptomatology was a significant mediator of the male emotional abuse-perpetration and the female emotional/physical abuse-victimization links, indicating a gendered patterning to findings.ConclusionsThese results indicate that: (1) CPS youth are a high priority group for dating violence and PTSD-linked intervention; and (2) CPS youth continue to experience the unique negative impact of childhood emotional abuse in their adolescent adjustment. All CPS children should be evaluated for emotional abuse incurred, and appropriate intervention attention be given as to how it specifically impacts on the child's approach to relating to themselves and to others.Practice implicationsThe present study directs practice implications in regards to: (1) the problem of teen dating violence, (2) the salience of childhood emotional abuse; and (3) the importance of targeting PTSD symptomatolgy among CPS youth. A substantial number of CPS youth report early engagement in violent romantic relationships and require support towards attaining the non-coercive relationship experiences of their non-CPS-involved age mates. The topic of dating, healthy dating relationships, and dating violence may need to be part of the regular casework, with a view towards supporting youths’ conceptualization of and skill set for healthy, close relationships. Further, this knowledge needs to be translated to foster parents and group home staff. With regard to the impact of childhood emotional abuse, CPS workers need to be sensitive to its potential for long-term, unique impact impairing relationship development. Emotional abuse is (a) unique among genders (i.e., for females, it clusters with physical abuse) and (b) uniquely predictive of PTSD symptoms and dating violence. Finally, as is consistent with theory and biopsychosocial evidence, PTSD symptomatology is a key causal candidate for understanding maltreatment-related impairment. Attention to targeting PTSD symptoms may be preventative for dating violence; attention to targeting emotional abuse experiences may be preventative for PTSD symptoms. CPS youth are an important population to involve in research, as their inclusion adds to the evidence-base to achieve evidence-informed practice and policy within child welfare.     

More like real life-Motivational methods of teaching in upper secondary school

Motivational methods of teaching are topical subjects and much discussed issues regarding schools and education. The first question of our study covers student motivation and students＇ perception of their own schools＇ teaching methods. The second question reflects on how upper secondary school teachers perceive their roles as teachers, their thoughts on acquirement of knowledge and how learning takes place. The third question treats the subject of how school and education is organized. The upper secondary school the authors chose for the case study is a school that recruits students on a national basis and is directed towards the education of fire and rescue service personnel. The programme follows the national science curriculum and gives qualification for further studies at most universities. The school started in the autumn of 1998 and is known for being successful at working with student involvement, responsibility and subject integration. The study which was conducted during the autumn of 2007 included 32 students from two of the learning groups from the same year and started on the day of introduction of a new theme and finished with their presentation of results. The authors made observations, interviewed and through questionnaires studied how students comprehended the schools＇ working methods. We also interviewed their teachers and headmaster. The theoretic standpoint is Activity Theory （Chaiklin, S. ＆ Lave, J. 1996; Knutagard, H., 2002; Vygotsky, L. S., 1986）. The conclusions are that the students are encuitured into a school＇s activities that are similar to what students perceive as that of real life. It gives meaning and motivation to learning and makes it meaningful. They identify their own responsibility and cooperative learning as the most important parts. The teachers＇ own learning process and planning work is parallel to the work forms applicable to the students. They are all interdependent of each other since all the work areas are thematic. The school can be seen as an activity system where members interplay and communication develops a common culture.     

An Integrative Perspective on Students’ Proportional Reasoning in High School Physics in a West African Context

This study examines students’ use of proportional reasoning in high school physics problem‐solving in a West African school setting. An in‐depth, constructivist, and interpretive case study was carried out with six physics students from a co‐educational senior secondary school in Nigeria over a period of five months. The study aimed to elicit students’ meanings, claims, concerns, constructions, and interpretations of their difficulty with proportional reasoning as they worked on a series of 18 high school physics tasks. Multiple qualitative research techniques were employed to generate, analyse, and interpret data. Results indicated that several socio‐cultural, psychosocial, cognitive, and mathematical issues were associated with students’ use of proportional reasoning in physics. Students’ capacity to reason proportionally was not only linked to their difficulty with the concept, structure, and strategies of proportional reasoning as a learning and problem‐solving skill, but was also embedded in the social, cultural, cognitive, and contextual elements involved in the learning of physics. The study concludes with a discussion of the implications for teaching high school physics.     

Applying the Mastery Learning Model to Sight Word Instruction for Disabled Readers

The present study evaluated the effect of applying a mastery learning model to sight word instruction for learning disabled (LD), elementary school children. A total of 48 LD children were taught 30 sight words in 9 lessons which incorporated mastery learning strategies, and a comparison group (W = 16) with methods that are typically used in the teaching of sight words. While all children could read less than 10% of the words on the pretest, the experimental group achieved over 90% accuracy on the posttest. This was higher than the average posttest performance of the comparison group (72% accuracy). Results of this investigation suggest that a majority of LD children can reach mastery on sight words within a reasonable time framework if sound remedial principles are applied consistently. The procedures described in this paper can serve both as a model of effective sight word instruction and as a diagnostic, trial-remediation technique for a disabled population.     

Focus Group Effects on Field Practicum Preferences

ABSTRACT

During the coming years the need for professionals to work with the nation's elders will increase several fold. This will place a great responsibility on university educational programs to prepare enough qualified future professionals to work in the greatly expanding field of gerontology. Prior research has identified several nonacademic and academic experiences that influence a student's decision to become gerontological professionals. One area that has been omitted from this work concerns focus groups. This article reports on the impact that observing a relatively simple and inexpensive focus group of professional geriatric practitioners can have on field practicum preferences among advanced undergraduate social work students at a large Texas state university. Findings indicate that observing a focus group significantly influences students' practicum preferences for working with elders, thereby setting them on a trajectory for a career in geriatrics.
