In-vivo studies on the motoric activity of the receptacular complex in females of the black field cricket (Orthoptera: Gryllidae)

Motoric activity of the receptacular complex situated in the caudal part of the female abdomen was studied in detail for the black field cricket, Teleogryllus commodus (Walker, 1869). By application of the previously introduced window method the number of peristaltic organ contractions per minute was counted, whereby four experimental series (virgins, mated females, ovipositing females, post-oviposition animals) were defined, with the number of examined crickets amounting to 20, respectively. According to the results obtained from experimental work, highest activity of the receptacular complex can be attested for females standing in the oviposition phase (26.35 ± 4.99 contractions per minute), whereas post-oviposition females are characterized by lowest activity (13.95 ± 3.90 contractions per minute). Except for virgins, where the number of peristaltic contractions increases with age, no significant correlation between motoric activity of the receptacular complex and adult age could be found. It is argued that in-vivo motoric activity of the receptaculum seminis and the ductus receptaculi is associated with the female fecundity cycle reaching its peak at the 10th day of the adult life stage.

THE INFLUENCE OF PLAYING BALL TOWARD MOVEMENT ACTIVITY ABILITY TO HYPOACTIVE AUTISM CHILDREN

Hypoactive autism children were indicated by slow motoric activity so that it caused the children difficult to move. The children tended passive and they did not have any interest to do movement activity and preferred alone when they looked their friends playing. To help hypoactive autism children in enhancing movement activity ability it required a game which attracted the children’s interest to move i.e. through playing game. The purpose of this research was to analyze movement activity ability before and after giving intervention using playing ball (passing and shooting), with time allocation 10 times meeting and 8 times intervention. This research used quantitative approach with the one group pretest posttest design. The subjects were 5 hypoactive autism children. For data analysis this research used statistic non parametric formula of sign test kind and the method of data collection applied observation and test. From the research result which was then analyzed by using sign test formula, it was obtained that the value of Z counting 1,78 while the value of Z table with critic value 5% one side test was obtained 1,64 so that Z counting 1,78 was greater than Z table1,64 it meant that null hypothesis (Ho) was refused and work hypothesis (Ha) was accepted. In this way it could be concluded that playing ball influenced toward movement activity ability of hypoactive autism children

THINK PAIR SHARE: ALTERNATIF PENINGKATAN AKTIVITAS DAN HASIL BELAJAR IPA

The action research figured out about the effectiveness exploration of a new alternative in Think Pair Share (TPS); with Kemmis & Taggart Model, for science, Ilmu Pengetahuan Alam (IPA) subject. The research cycled the TPS within listening, observing, mentality, emotionality, and motoric activity. First of all, the cycle I signified that the students have lower inquiry in mentality. It had been observed on the lower frequency of asking-giving opinion portions. Secondly, the cycle II signified that there is a not slightly difference of inquiry, however, the students indicated response more than the previous cycle. The third cycle signified a response to the executed activity. It projected students’ determination and enthusiastic in asking-giving opinion within the activity. The cycles mean score estimated 65 for the first one, increased to 74 in the second cycle, and reached 85 in the last cycle. The students’ achievement stimulated the test instruments significantly. In conclusion, the action research about the new alternative in TPS; with Kemmis & Taggart Model proves effective to SD Negeri Gampong Teungoh, Kota Langsa. It is suggested to be applied in science for elementary school subjects as one of the teaching techniques. Keywords: Think Pair Share, learning Activity, and Students’Achievements.
