Abstract This study investigated the effects of pseudoword discrimination training that either required or didn’t require selection responses upon control by stimulus elements and recombination of elements, and upon stimulus observation. Eight undergraduate students were exposed to two conditions with discriminative training and stimulus control test. Condition SEL required selecting the S+, and condition OBS only required observation. Test results suggest that selection responses did not affect control by the elements or the recombination of elements in the pseudowords. Four participants presented restricted stimulus control. This control was extended in the additional DOR condition, which required differential observation of the elements, and was accompanied by increases in S+ observation. Increased stimulus control, promoted by the DOR, should still be evaluated independently of previous teaching conditions.

Fatigue Endurance

Fatigue tests are carried out for 16MnR welded joint under constant strain control. Test results reveal that 16MnR weld metal exhibits characteristic of cyclic softening and non-masing obviously. The strain–life curve can be best described by the three-parameter equation. It shows the fatigue endurance limit in the heat-affecting zone (HAZ) of welded joint is lower than that in the weld metal.

The primary goal of the present study is to identify the problematic areas in the pronunciation of the letter “g” in English written words made by Saudi female learners of English as a foreign language, and the reasons for the weakness associated with mispronunciation of English written words which contain this letter. The population of the study was the female students (90 students) and their English language teachers (12 teachers) at the Qassim University during the academic year (2014-2015). There were two types of instruments used in this study. The first was a pronunciation test for the student participants in order to investigate the problematic areas of pronouncing “g” in different environments in different words; and the second a questionnaire for the teacher participants to provide comprehensive data about the causes of these errors of pronouncing “g” committed by EFL female students at Qassim University. Ninety female students were included for the pronunciation test and 12 teachers were asked to answer the questionnaire. Simple percentage was used for analyzing the data of recording words (pronunciation test). Results of the students’ recording words revealed that the participants mispronounced “g” before nasals (68%). According to the results of the teachers’ responses to the questionnaire suggested many factors that can cause difficulties for students in terms of pronouncing “g” in English written words. According to them, these difficulties are concerned with reading difficulties, nonstandard spellings, letters that follow “g” (many of them may become combinations), loan words, orthography (no correspondence between the English alphabets and their sounds). The researcher offers recommendations that might help teachers and students to overcome and reduce these mispronunciations of this letter in English written words.

Biological Phenomena

Research in developmental psychology has shown that deeply-rooted, intuitive ways of thinking, such as design teleology and psychological essentialism, impact children’s scientific explanations about natural phenomena. Similarly, biology education researchers have found that students often hold inaccurate conceptions about natural phenomena, which often relate to these intuitions. In order to further investigate the relation between students’ conceptions and intuitions, we conducted a study with 93 first year undergraduate students in biology. They were asked to express their level of agreement or disagreement with six misconception statements and to explain their choices in a two-tier test. Results showed a tendency for students to agree with teleological and essentialist misconceptions. However, no association was found between students’ teleological and essentialist conceptions as expressed in their agreement or disagreement with the various misconception statements. Moreover, we found evidence of a variable consistency across students’ answers depending on the misconception considered, which indicates that item features and contexts may have an effect on students’ answers. All together, these findings provide evidence for considerable persistence of teleological and essentialist misconceptions among students. We suggest future directions for thinking, studying, and analyzing students’ conceptions about biological phenomena.

This article was prepared based on qualitative research, case studied with research subjects 36 undergraduate students of mathematics education study program FMIPA UNNES in elementary linear algebra. Intended to find out students’ problem solving abilities aspects of algebraic creative thinking and to describe connections between aspects of students creative thinking in solving problems. Aspects of creative thinking include: fluency, flexibility, novelty, and elaboration. Data obtained through tests, observations, and interviews. Based on the analysis of the test results, as many as 17 students reached the minimal criteria which is at least 61, and 15 students worth under 61. This indicates that many students had difficulty in solving problems of elementary linear algebra that contain aspects of creative thinking. The creative thinking character ofstudentsinsolvingproblemsofelementaryalgebrawithaspectsofcreativethinking; based on data analysis, obtained information that students in solving problems generally tend to thought on aspects of fluency. Some students had difficulty thought intermsofflexibility.Onlyafewstudentsthoughtofthenoveltyaspect.Manystudents had difficulty thought about aspects of elaboration. In connection between aspects of creative thinking there were several sequence patterns in thought when solving problems. Only a few of the four aspects of creative thinking were patterned on the minds of students.
