The effect of schooling upon understanding of selected science terms

Eight science terms were studied as to their meanings for 9-, 13-, and 17-year-old students randomly selected from a single school district in the midwest. The results indicate that the school is ineffective in increasing numbers of students who master the select terms between seventh and eleventh grade. On three of the eight terms 9-year-olds perform as well as 17-year-old students. Although there is growth between ages 9 and 13 on degree of mastery for five terms, some of these differences can be attributed to increasing student abilities to read, increases in student experiences with school science and testing procedures, maturation and development of reasoning for students across grades, and the relative emphasis of science content/terminology for the various age levels.     

Does training matter? Comparing the behaviour management strategies of pre-service teachers in a four-year program and those in a one-year program

Survey-based research was conducted with Australian pre-service teachers to identify the classroom management strategies that they would employ, their confidence in employing them, and the effectiveness of the strategies. Furthermore, the study aimed to identify significant differences in these variables between pre-service teachers in the final year of a four-year teacher training course and pre-service teachers undertaking a one-year, stand-alone teaching program. The results of this study indicate that the most frequently reported strategies by all the Australian pre-service primary teachers surveyed were rewards and initial corrections. The pre-service teachers were selective in the type of corrective strategies they would employ, with a preference for relatively less intrusive reactive strategies. All of the pre-service teachers here found rewards and preventative strategies to be the most effective. The only significant differences found between the four-year trained and one-year trained pre-service teachers were around preventative strategies. Specifically, four-year trained pre-service teachers employ preventative strategies significantly more often than pre-service teachers in the one-year teaching course. Similarly, four-year trained pre-service teachers are significantly more confident in using preventative strategies than those in the one-year course. The implications of the results for teacher education programs are considered.     

The I files,the truth is out there: science teachers’ constructs of inquiry

This article is concerned with the personal constructs of science teachers about inquiry in selected schools in the Yorkshire and the Humber region of England. While there is a large volume of existing literature which advocates the use of inquiry in the science classroom to enhance students' engagement with, and learning of science, relatively few of these studies represent teachers' voice. Therefore, we believe that it is important and distinctive to report teachers' constructs of inquiry and related concerns regarding its use in the science classroom. We identify the key constructs from 10 participating teachers and discuss these amongst a backdrop of policy implications for inquiry approaches in English secondary school science classrooms. Personal Construct Theory was used to underpin the study and frame data collection and analysis. Key findings show that the teachers identify an inquiry approach as being effective in stimulating students' independent learning and interest in science but issues such as time and confidence inhibit their deployment of inquiry approaches.     

A Developmental Model of Reading Acquisition Based upon Early Scaffolding Errors and Subsequent Vowel Inferences

This paper investigates the processes that predict reading acquisition. Associations between (a) scaffolding errors (e.g., “torn” misread as “town” or “tarn”), other reading errors, and later reading and (b) vowel and rime inferences and later reading were explored. To assess both of these issues, 50 6‐year‐old children were shown a number of CVC words, and word reading errors were noted. Children were then taught families of riming words that could serve as a basis for rime or vowel analogies (e.g., “bark”, “mark”, “dark” → “park” or “harm”) before attempting to read the CVCs a second time. Children’s reading ability was measured at age 6 and two years later at age 8. The results showed that, among word reading error groups, only scaffolding errors at age 6 were unique predictors of reading at age 8, after reading, vocabulary, and phonological awareness were controlled. Vowel but not rime inferences predicted reading at age 8. The results are used to inform a model of the role of phoneme awareness and grapheme use in early reading development wherein vowel inference‐use helps to specify precise representations of CVC words from preliminary scaffolding errors.     

Discovering frequently recurring movement sequences in team-sport athlete spatiotemporal data

Athlete external load is typically analysed from predetermined movement thresholds. The combination of movement sequences and differences in these movements between playing positions is also currently unknown. This study developed a method to discover the frequently recurring movement sequences across playing position during matches. The external load of 12 international female netball athletes was collected by a local positioning system during four national-level matches. Velocity, acceleration and angular velocity were calculated from positional (X, Y) data, clustered via one-dimensional k-means and assigned a unique alphabetic label. Combinations of velocity, acceleration and angular velocity movement were compared using the Levenshtein distance and similarities computed by the longest common substring problem. The contribution of each movement sequence, according to playing position and relative to the wider data set, was then calculated via the Minkowski distance. A total of 10 frequently recurring combinations of movement were discovered, regardless of playing position. Only the wing attack, goal attack and goal defence playing positions are closely related. We developed a technique to discover the movement sequences, according to playing position, performed by elite netballers. This methodology can be extended to discover the frequently recurring movements within other team sports and across levels of competition.     

On the Meanings of Self‐Regulation: Digital Humanities in Service of Conceptual Clarity

Self‐regulation is of interest both to psychologists and to teachers. But what the word means is unclear. To define it precisely, two studies examined the American Psychological Association's system of controlled vocabulary—specifically, the 447 associated terms it presents—and used techniques from the Digital Humanities to identify 88 closely related concepts and six broad conceptual clusters. The resulting analyses show how similar ideas are interrelated: self‐control, self‐management, self‐observation, learning, social behavior, and the personality constructs related to self‐monitoring. A full‐color network map locates these concepts and clusters relative to each other. It also highlights some of the interests of different audiences, which can be described heuristically using two axes that have been labeled abstract versus practical and self‐oriented versus other‐oriented.     

Effect of environmental constraints on multi-segment coordination patterns during the tennis service in expert performers

The aims of this study were to examine the effect of different environmental constraints on kinematic multi-segment coordination patterns during the service and its coordination with service time variability. Ten expert tennis players (Age: 34.1 ± 5.3) volunteered to take part in this study. Participants served 30 times in 3 different conditions: control, target and opposition. The order of conditions was counterbalanced between participants. A wireless 3D motion capture system (STT Co, Spain) was used to measure 7 joint motions, with a 17 degrees of freedom biomechanical model created to capture the entire service action. Results of the principal component analysis showed that 4 synergies were created; however, their roles were changed relative to the perception of the environment. The results of repeated-measures analysis of variance did not show any significant difference on total variance and individual principal components between conditions; however, one synergy pattern significantly predicted the service time variability in both control and opposition conditions. In conclusion, the findings demonstrated that expert performers reduce the joint dimensionality by creating functional synergies in different phases of service and adapt the service action according to the perception of the environment.
